The Living Terra Firma, Vol.1, No.1, June 2022 Editorial Dear nature lovers, Foundation for Ecological Welfare (FEW) is a not-for-profit Foundation with a goal of bringing in ecological welfare for the human society. For bringing the ecological welfare, its main emphasis till date is to create ecological awareness and sensitization. To create ecological awareness and sensitisation towards wetlands’ importance and need of their conservation, Founding Directors of FEW had been publishing a wetland e- Magazine “Jalaplavit” (ISSN 2321-1881) since 2009. Now, after about 1.5 decades, the Founding Director has decided to start another eMagazine that will speak for importance of terrestrial
The Living Terra Firma, Vol.1, No.1, June 2022 ecosystems like forests, scrublands, grasslands, deserts, savannahs and even rural and suburban ecosystems. All these ecosystems are throbbing with living organisms of one or the other types. And therefore, this eMagazine on your computer or smartphone is aptly called “The Living Terra Firma”! Friends, this is just a beginning. The issue in front of you is the first issue. It is actually published to mark the World Environment Day 2022. But as this is a voluntary activity, there has been a scarcity of time to work on it and bring it to the final shape. That is why its soft launch is delayed by over a month’s period. But, the Founding Editor is sure that the things will come on track. It is decided that FEW will publish (only soft launch) two issues of “The Living Terra Firma” (usually on around World Environment Day and World Soil Day in December) and two issues of “Jalaplavit” (ISSN 2321-1881; usually on around the World Wetlands Day and the Wildlife Week of India). I appeal all of you not to be just good readers of this eMagazine but also to contribute as authors of research papers, popular articles, observation/miscellaneous notes, reviews etc. Photographers are welcome to contribute their photographs. I also look forward to receive your comments on the issue through your emails to [email protected]. Ketan Tatu, Ph.D. Founding Editor
The Living Terra Firma, Vol.1, No.1, June 2022 Asian Pied Starling (Gracupica contra) and its Expanded Distribution Range in India with Emphasis on Gujarat State P. S. Thakker Email: [email protected] Swarup Fullonton 5
The Living Terra Firma, Vol.1, No.1, June 2022 Jatt Mahammadhasan Usmanbhai Introduction Distribution of Asian Pied Starling (Pied Myna) in India covers the region east of a line in north-south direction from Ambala (Haryana) to Hyderabad and Masulipatanam (Andhra Pradesh); north-eastern states to Myanmar; from Himalayan foothills to the north extending towards South India up to Krishna River in Andhra Pradesh through Madhya Pradesh. In India, the bird is widespread in Eastern Ghat mountain range and the entire part of West Bengal, Bihar, Jharkhand, Andhra Pradesh and Telangana (Ali, 2012). Distribution shown by Ali & Ripley (2007) and that by Grimmett et. al. (2011) is shown in Figures 1a & 1b. Habitat of this bird constitutes open country and cultivation. Generally, the bird can be seen in the neighborhood of villages, towns and cities. The bird is seen in presence of grazing cattle, particularly on moist or marshy environs of village tanks. The Nesting season is during March to September (Ali, 2012). As per the IUCN Red List of Threatened Species, the bird is Least Concern (LC) and its population trend is mentioned as “increasing”. 6

(Source: eBird). Gupta and Maiti (2011) made habitat wise comparative assessment and assessment of seasonal patterns of abundance of Common Myna (Acridothere tristis), Asian Pied Starling (Gracupica contra) and Jungle Myna (Acridotheres fuscus) by conducting surveys twice a month. Abundance of Common Myna was found to be the highest, followed by that of Asian Pied Starling and Jungle Myna. Sinu (2011) has stated that Asian Pied Starling is one of the dominant insectivorous birds of tea plantations in North-East India. 7
The Living Terra Firma, Vol.1, No.1, June 2022 The author had seen the bird long back during 1980s in and around Bharatpur in Rajasthan and in Panna district of Madhya Pradesh during the year 2011. It was found to be a common species in the region. Dr. Jugal Kishore Tiwari had reported unusual nesting site of this species at Bharatpur, Rajasthan in the year 1992. According to Grimmett et al. (2011), the bird is resident of India, wide spread in North, Central and Eastern sub- continent. Sharma (2004) had reported the species in Jaipur, Bhilwara, Jhunjhunun, Udaipur, Ajmer city, Kishangadh & Nasirabad in Ajmer district, Badmer, Bikaner, Jodhpur, Jaisalmer, Nagaur, Sikar, Hanumangadh, Alwar, Tonk, Bundi and Kota in the state of Rajasthan. The species is found mainly in the plains and foothills up to 700 m above the mean sea level. The presence of this bird outside distribution range was reported at Mumbai in the year 1953. this species was introduced in Mumbai of Maharashtra state, India (Rasmussen & Anderton, 2005). Expanding distribution range of Asian Pied Starling in Gujarat state Late Mr. Lalsinh M. Raol had seen three individuals of this species on 18-3-1961 at Rajkot in Saurashtra, Gujarat. This might be the first record of this species in Gujarat. Later, he saw the species on 18-3-1966 at Darbargadh at Jasdan in Saurashtra. He published his observations as “Unexpected Bird” in the “Newsletter for Birdwatchers” in the year 1966. In addition to Mr. L.M. Raol’s first record at Rajkot in 1961 and later at Jasdan in 1966, Mr. Anil Dhamelia photographed the bird at Kheda, Kheda district (Central Gujarat) on 1-1-1970. Another photographer Mr. Akshay Kumar Mathur also took photograph of this bird at Ahmedabad on 1st January 1970. As the above-mentioned birds were recorded at the sites outside the known distribution range, the birdwatchers and ornithologists of that time-frame believed that the recorded individuals could be the birds escaped from captivity. Until about a decade ago, any sighting of Asian Pied Starling in Gujarat state was considered to be a rare sighting in the state. Balar (2007), in his book “The Birds of Gujarat”, has mentioned this bird as “Vagrant” in Gujarat”. Late Mr. L.M. Raol, in his book (in Gujarati) “Weed Vagadaa naan Pankhi” has also described this bird as rare bird in Gujarat. Ganpule (2016) has also mentioned this bird as rare/vagrant in Gujarat state. But he has also mentioned that there are many isolated records and not all could be escapees. He has also mentioned breeding record in Dahod and a nest-record in Jamnagar. 8
The Living Terra Firma, Vol.1, No.1, June 2022 R. B Balar The inclusion of Dahod (Dohad) region spread of distribution range of this bird in Gujarat in the town of might have been due to the occurrence of this bird in the adjoining area/regions of Rajasthan and Madhya Pradesh, where birds occur in large population. Thus, distribution of Pied Myna is there in Eastern Gujarat. Mr. Bharat Rughani had recorded this bird at Kuchhadi near Porbandar in April 1999. He had published his observation note in “Vihang” bird magazine in the year 2000. Later, he saw this bird at Gosa Bara wetland during the year 2018. Mr. Yashodhan Bhatia and Mr. Jaypalsinh Jadeja had seen one bird at Vibhapar village on the outskirts of Jamnagar in the year 2004-05. They had also recorded a nest constructed by this bird on an electric pole. This has been reported by Mr. Prasad Ganpule in his report in the year 2016; by Monga & Navroji in the year 1983 and Chaudhary and Desai in the year 2021 in their work. Shri Ashwin Trivedi has photographed this bird at Jamnagar. Monga and Naoroji (1983) mentioned sighting of Pied Starling in Jamnagar and South Gujarat as rare / vagrant. (In: Chaudhary and Desai). Avi Base–The World Bird Data base-has shown occurrence of this species in Devbhoomi Dwaraka, Jamnagar, Morabi and Surendranagar districts. I personally contacted Mr. Chku Vora and Mr. Yogendra Shah for the records of this bird in Surendranagar district. But they had not seen this bird in this region. However, the species has been reported in the Bio Diversity Report of Wild Ass Sanctuary prepared by LEA Associates South Asia Pvt. Ltd. New Delhi. In the report, in section of avi- fauna, the Asian Pied Starling has been listed in the study area. The bird was reported in the study area during transit survey from Dhrangadhra to Kuda. Thus, in the Saurashtra region distribution of this species covers districts like Porbandar, 9
The Living Terra Firma, Vol.1, No.1, June 2022 Surendranagar, Morabi, Jamnagar, Devbhoomi Dwaraka, and Rajkot since long (about sixty years). The species is common and breeds in Dahod district in Eastern Gujarat and now considered to be a common species. I had seen the species in Dahod in the year 2008. Mr. Ajay Desai has reported breeding of Asian Pied Starling at Dahod in the year 2005 and published a note regarding it in a Gujarati newsletter “Vihang” (Desai, 2006). Mr. Juzar Boriwala and Mr. Akil Kharodawala had also seen this species on 22-6-2005. Mr. Shakir Kadiwala had published a note in the Gujarati newsletter “Vihang” (Kadiwala, 2007). In this asticle, he has mentioned that he had been seeing this species of starling in Dahod since last five years i.e., from the year 2003 to 2008. He had also mentioned the starling’s nests were present at many places in the month of June 2006. After mid-2010s, there have been reports of sightings of this species from Vadodara district. The sites of sightings include Vadodara city, Timbi Lake and Wadhvana Lake. The bird was reported from Vadodara city, Vallabh Vidyanagar, and Anand by Late Dr. B.M. Parasharya. Dr. Anika Tere has also seen Asian Pied Starling at Timbi Lake, Wadhvana Lake and at Vadodara city. Mr. Vishal Shah has taken photograph of this bird at Wadhvana Lake on 31-12-2017. Mr. Gopi Rajgopal also took photograph at Wadhvana Lake on 11-3-2018. Mr. Mayur Patel photographed the species at Timbi Lake on 23-12-2018. Mr. Bhavya Joshi also photographed this bird at Wadhvana Lake on 6-1-2019. Mr. Sahdev Zala photographed an individual of this species in Kheda town on 16-6-2019. Anish Khira photographed this bird at Timbi Lake near Vadodara on 20-12-2019, 19-1-2020, 26-9-2020 and 9-1-2022. Mr. Jay Patel photographed the species at Timbi Lake on 17-2-2021. Dr. Jitendra A. Patel, Mr. Harish Joshi and the author of this article (Dr. P.S. Thakker) saw this bird at the village tank of Chakalasi village near Nadiad in Kheda district on 21-3-2020. Mr. Anil Dhamelia had taken a photograph of the species at Dahiyap in Kheda District on 1-1-1970. Mr. Soham Brahmabhatt also had taken a photograph of the Asian Pied Starling this bird at Lambhvel village of Anand district on 20-1-2014. Mr. Tim Tucey has taken photograph at Lambhvel near Anand on 21-4-2022. Thus, in the Central Gujarat region, the Asian Pied Starling is distributed over Kheda, Vadodara and Anand districts. As mentioned earlier, Mr. Akshay Kumar Mathur took a photograph of this bird in Ahmedabad on 1-1-1970. Recently Mr. Kailash Jani has taken photograph of Asian Pied Starling on 1-7-2021 at Dantiwada Reservoir constructed on Banas River in Banaskantha district. Mr. Ayaz Mansuri had reported sighting of this bird from Polo 10
The Living Terra Firma, Vol.1, No.1, June 2022 Forest of Vijaynagar forest range in Sabarkantha district on 29-8-2021. Mr. S. V. Chaudhary and Mr. P.G. Desai had observed this species on the way to Vadnagar and at Kheralu town, Mehsana district on 5-4-2021. The observation was also published in “Species” in the year 2022 (Chaudhary et al., 2022). Thus, the distribution range of this species include the districts like Banaskantha, Mehsana and Sabarkantha in North Gujarat and Ahmedabad in Central Gujarat. Kailash Jani This species has been reported/photographed in the districts like Bharuch, Surat, Navsari, Narmada and Valsad Districts of South Gujarat. Mr. Jugal Patel has sighted the species at Adol village of Bharuch district and has reported the same in eBird. Dahya et al. (2021) has recorded the species in BKM Science college campus Valsad. Mr. Mehul Patel had collected photographic record of this bird at Kotha village, Gandevi Tauka of Navsari district on 15-11-2020. Mr. Anand Patel photographed this bird on the outskirts of Hajira, near Surat on 29-11-2020. Mr. Dipakbhai Patel took picture of the bird at Kotha village, Gandevi Taluka of Navsari district on 25-12-2020. BirdLife International has reported this bird in Narmada district. Thus, Asian Pied Starling is spread over Bharuch, Surat, Navsari, Narmada and Valsad districts in South Gujarat. Considering whole Gujarat state, the spread / distribution range of this species in Gujarat includes North Gujarat, Eastern Gujarat, Western Gujarat, Saurashtra, Central Gujarat and South Gujarat. It can be concluded that distribution range of Asian Pied Starling has expanded in Gujarat between 1961 and 2022. This range expansion might be due to the increase 11

According to him Kasambe the bird is resident of Maharashtra state and had distribution all over the state. In the past, this species was introduced in Mumbai city in the year 2005. Rajasthan The westward spread of this species in India, particularly in parts of Rajasthan has been aided by changes in irrigation and farming patterns. Recently, the species was reported from Todgarh Raoli Wild Life Sanctuary in 2020 (Purohit et. al, 2020), Delhi A pair of Asian Pied Starling was filmed near its nest in Delhi during summer months in the year 2021 by Wilderness Films India. Photograph of this bird was taken by Mr. Manish Kumar on 30-11-2012 at IIT Delhi. Punjab Ms. Navdeep Kaur and Mr. Manoj Kumar have recorded this species at Faridkot in Punjab in 2018 (Kaur and Kumar, 2018). They have reported this bird breeding in the premises of Punjab Agriculture University located in Ludhiana (Ludhiana District). The bird has also been photographed by Mr. Vivek Saggar at Hiana Kalan village in Patiala district on 11-3-2022. Haryana Mr. Alok Tewari had photographed this species in Sadhrana, Gurugram and Basai Wetland, Gurugram, Haryana. 13
The Living Terra Firma, Vol.1, No.1, June 2022 The species was known to be present in Haryana earlier, but the above- mentioned photographic documentation was carried out at Gurugram. Mr. Rahul Sharma had photographed the species at Sultanpur Bird Sanctuary on 10-4-2016. The distribution range of this starling has expanded westward and north-westward in Rajasthan and Punjab from Ambala (Haryana). Jammu (J&K) Nest characteristics and nesting success were studied from May 2013 to September 2015 in Jammu region of J & K (Kumari et al., 2018). Out of 82 nests, 55 nests were studied by Ms. Meena Kumari, D. N. Sahi and Ms. Seema Langer. Most of the nesting trees were found in vicinity of different water body viz. canals, streams, ponds and marshes. Uttarakhand Tyagi and Lamba (1984) in a report of the Zoological Survey of India (ZSI) mentioned that the Indian Pied Myna does not breed round the year. At Dehradun it was observed to have a single breeding season of about six months from late February to the end of August. Ms. Sweta Bhattacharya and her colleagues had studied the bird in Pauri district (Gadhwal Himalayas) of Uttarakhand. They published the work in the year 2021. The bird was photographed by Devang Patel at Sat tal, Nainital district, Uttarakhand on 21-5-2018. Later, the bird was reported from Dehradun on 18-9-2021. Andhra Pradesh Earlier distribution range of Asian Pied Starling in South India was up to Krishna River, but now the species is also reported from southern Andhra Pradesh. Tamilnadu The species is reported from Chennai in Tamil Nadu State recently. According to reports published in the Times of India (April 22, 2018), and The Hindu (January 1 & 4, 2022), the species is recorded on outskirts of Chennai. According to Mr. V. Santhram, the species exists at Poondi Reservoir on Chennai outskirts since the year 2010. A pair of Asian Pied Starling was seen in Pallikarnai in the month of April 2018. The first sight record of Asian Pied Starling was from near Chennai in August 2010, when Mr. Gnanshankar Keshav Bharathi and his birder friend documented the species near the Poondi Reservoir. In the year 2019, Mr. Arvind A M reported breeding 14
The Living Terra Firma, Vol.1, No.1, June 2022 of this bird near Chennai. Photograph of Pied Myna was taken B. Balaji at Coonoor in Nilgiris in Tamilnadu. Conclusion Based on the above discussion, one may infer that the spread of Asian Pied Starling (Pied Myna) has increased in Delhi, Haryana, Punjab, Uttarakhand, Jammu region and POK (J &K), Himachal Pradesh, Gujarat, Rajasthan, Andhra Pradesh, Telangana (which was earlier part of Andhra Pradesh), Karnataka, and Tamil Nadu states. These above-mentioned districts should be considered as addition to the species earlier known distribution covering Madhya Pradesh, Jharkhand, Chhatisgadh, Bihar, Orissa/Odisha, and North-East states in India.

The Living Terra Firma, Vol.1, No.1, June 2022 A “Star” on the Land Under Threat: Indian Star Tortoise (Geochelone elegans) Raju Vyas Email: [email protected] Indian Star Tortoise (Geochelone elegans) Modern man's urge for intense urbanization and rapid industrial development has put many reptilian species into trouble as these two phenomena expose them to numerous threats of varying extents. These threats lead to a series of events which negatively impact long-term survival of native reptiles, pushing some reptilians to the brink of extinction and some others vulnerable to it, like the Indian Star Tortoise (Geochelone elegans). This tortoise is widely distributed in Pakistan (east), India and Sri Lanka and is known by three discontinued populations, i.e. western, southern and island populations (Table 1; Figure 1). It is confirmed genetically too (D'Cruze et al., 2018). Indian Star Tortoise is legally protected in the native ranges of these three countries by their 18
The Living Terra Firma, Vol.1, No.1, June 2022 respective national/provincial legislations. In India, it is protected under the Indian Wildlife (Protection) Act, 1972, in Sri Lanka, the tortoise is protected by the Sri Lankan Fauna and Flora Protection Ordinance of 1938 (Amendment, 1993). In Pakistan, it is protcted by the provincial legislation of the Sind Wildlife Protection Ordinance 1972. (It may be noted that Sind Province is the only natural range in Pakistan.) The Indian Star Tortoise (IST) faces various small to significant natural and other threats in wilderness in the range countries (Table 2). The most severe threat to the species is the illegal collection of massive number of tortoises from nature and their smuggling for commercial pet markets or as on captive breeding stocks (Vinke & Vinke, 2010). It is observed that IST is the favourite pet in the world. Therefore, this species is synchronic with the wildlife trade globally. Over the last three decades (1991-2021), the gathered information from various sources (like published scientific papers, newspapers, the internet and various official raids by the state forest department, pet traders and other enforcement agencies, including customs and export departments of native and overseas countries) indicated that over a 100,000 live ISTs were smuggled from nature, an alarming and an eye-opening fact. This trade-trend is rising day by day. Most of the tortoises were confiscated at international airports. Still, there exists an unseen complex network of smugglers, other modes of transactions and its other derivatives which are unknown to us. Overall, the illegal smuggling of IST is a massive trade. It is bigger and beyond our anticipation. What we can imagine is merely the tiny tip of a gigantic iceberg. Records and figures of tortoises victimized by this trade speak of only those specimens confiscated before reaching the final destination. Still, the actual numbers of specimens collected from nature are presumably much larger. A high percentage of tortoises die during such transactions and before consignments are delivered to the target points because most of the confiscated tortoises are immature, small-sized juveniles or sub-adults (hardly a few months to 6-7 years old). It is impossible to quantify the effects and magnitude of the tortoise trade in Asia. Still, it is estimated that over 5000 individuals were annually exported. Within a decade, it is likely that 1,0000-2,0000 individuals are annually being captured illicitly from the wilderness. However, such illegal pet trade involving large 19
The Living Terra Firma, Vol.1, No.1, June 2022 number of tortoises have a significant impact on the entire wild population. This problem escalates two possibilities and thus adversely affects the species. On one hand, it may result into fewer percentages of new recruitments in the wild population and on the other hand, it leads to a possibility of genetic pollution between inter sub-populations and accidental introduction of new pathogens. A huge number of hatchlings, juveniles and sub-adults eradicated from natural ecosystems has direct negative repercussions on the global populace, resulting in fever or no new recruitments in nature, the parental stock becoming old and further older, leading to poor breeding performance and shrinkage in the population. It finally causes the entire population to suffer from the view point of a long term survival and existence in nature. Tortoises and Turtles Are tortoises and turtles different creatures? Well, all tortoises are in fact turtles; they belong to the order Testudines or Chelonia (reptiles having bodies encased in a bony shell). But, not all turtles are tortoises. The most important thing to remember about tortoises is that they are exclusively land creatures. As far as turtles are concerned they are usually freshwater and marine creatures. However, there are some exceptions as land turtles do exist, like Box Turtles and Wood Turtles. As far as anatomical features are concerned, the tortoises differ from other turtles in having elephantine (or columnar) hind limbs and hind feet. Their forelimbs are not flipperlike, and their hind feet are not webbed. And unlike turtles, all tortoises are vegetarians! (Source: Encyclopedia Britanica) 20

The Living Terra Firma, Vol.1, No.1, June 2022 When any sizeable illegal consignment is seized, a question arises regarding the original geographical location in the wild/native of the seized IST and how the stocks should return to the native country after the necessary scientific and official procedure. But such practice is not exercised when small consignments/fewer numbers of IST are seized overseas or at a national level, especially during raids by the Forest Departments in India. The authority immediately rushes and panics about releasing the stocks of animals into any nearby habitat without any concern or opinion from any experts. In such cases, due to the shortcut practice, the local population of IST suffers genetic pollution due to the in-between sub-population. Further, the healthy sub-populations of ISTs are prone to infections from new pathogens transmitted by the release of seized stocks. These two critical issues massively deplete the wild population of IST and inflate the pet trade trend. The causes responsible for these issues are 1) No ex-situ housing facilities for maintaining large numbers of ISTs within the range countries, and 2) lacunae in forensic protocols especially for tracing the geographic origin of seized stocks and mandating their return to their origins. The IST pet trade represents a chronic failure of the management and conservation policies formulated for this species' benefit and long-time survival. This issue must be recognized as a significant lethal threat to the natives and the global populace. Thus, enforcement of law, vigilant monitoring of trade, education and awareness programmes for local communities, provisions of alternative survival strategies (with proper solutions to the socio-economic problems of poor forest dwellers living in the vicinity of habitats of this species) may ultimately discourage the harmful elements of the human society from any sort of participation in the illicit pet trade. If this multi-pronged approach is not implemented seriousy, the earth may lose her “Star” within a short period. We should also consider all the recommendations of van Dijk et al. (2000) suggested in Cambodia Workshop (Asian Turtle Trade Working Group, 2000). 22

The Living Terra Firma, Vol.1, No.1, June 2022 Grasslands: Their Origin and Management in the Indian Subcontinent Prajnyan Sarma1 and Ratul Pegu 1Email: [email protected] Origin of grasslands According to Jacobs et al. (1999) grasslands seem to have existed for approximately 15 million years. Edwards et al. (2010) suggested that tropical grasslands originated around 10 million years ago, whereas their expansion began around 2 million years ago (Lehmann et al., 2016). Paleontological documentations support the existences of C4 plants back to the Miocene period. The origin of grasslands in the equatorial regions of Asia associated with monsoon can be traced back to fragmentation of Gondwana and subsequent rearrangements of the tectonic plates across the equatorial zone (Whyte et al., 1976). The period between Cretaceous and Oligocene was characterized with rapid movements of the tectonic plates ranging between 26 cm yr-1 to 16 cm yr-1 (Blow and Hamilton, 1975). In the initial period, the Indo-Australian region was characterized by tropical evergreen forest with prominent precipitations. However, the relative position of the Western Ghats and the formation of the Himalayan Mountain ranges increased aridity in the peninsular and northwestern region of the subcontinent respectively (Singh et al., 1983). Increase in the temperature towards the end of Pleistocene facilitated the diversification and extension of the herbaceous plants (Singh et al., 1983). In the last several millennia, anthropogenic activities have led to decrease in forest covers and increase in grass covers at a global scale. Whyte (1976) speculated that in western region of Asia, where impacts of monsoon are observed, the grasslands have recently originated. The plant species in these areas either originated from the pre-existing ancestral species through the events associated with evolution or from the species present in the neighboring arid regions (Singh et al., 1983). 29
The Living Terra Firma, Vol.1, No.1, June 2022 According to Singh (1976), the grasslands of India, Nepal, Pakistan and Sri Lanka are anthropogenic in origin with the alpine grasslands being exceptions. However, Joshi et al. (2018) mentioned that the generalized concept of grassland origin through anthropogenic activities is not uniformly applicable as the Shola-grassland mosaics in southern India are the remains of the vegetation from Pleistocene era. The existence of these mosaics’ dates back to more than 20,000 years (Sukumar et al., 1993). According to White et al. (1983), grasslands are naturally extended in those areas which are subjected to sufficient moisture availability and environmental conditions that specifically inhibit the growth of trees and shrubs. Over the years of existence, the grasslands often undergo contractions and expansions due to changes in the climatic conditions such as precipitations, droughts, temperatures, etc. The distribution of the plant species in grassland ecosystems are found to be highly influenced by temperature, aridity and CO2 level as they affect the physiologies and responses of C3 and C4 plants (Bond and Midgley, 2000; Lehmann et al., 2016). Besides climatic and factors, physical barriers like distances between neighboring grasslands also play key role in the distribution of species. Management of grassland Grasslands are important as they play an important role in carbon sequestration as a large portion of the grassland biomass is below ground. According to White et al. (2000), the high latitude grasslands have highest below ground carbon sequestration (271- 303 t C/ha) whereas the low latitude grasslands have the lowest (91-131 t C/ha). However, the carbon sequestered by grasslands throughout the world is often found to be comparable to forest due to their extensive distribution around the globe (Gibson, 2009; Boval et al., 2012). Carbon sequestered by the grasslands is influenced by the types of grasses and herbs present in the area along with rainfall, temperature, humidity, insolation, decomposition and practices adopted for management of the grasslands. Since grassland patches are often formed due to the occurrences of disturbances, it is often seen that recurrence of disturbances are necessary to prevent secondary successions in grassland patches. The disturbances can either be exogenous (e.g., drought, flood, fires, etc.) or endogenous (e.g., natural eradication of dominant plant 30
The Living Terra Firma, Vol.1, No.1, June 2022 species due to disease outbreak or overgrazing, etc.) on the basis of their initiation with respect to the community. Disturbances can also be categorized as biotic (e.g., herbivory, diseases, etc.) and abiotic (e.g., fire, drought, etc.). According to Veldman (2015), tropical grasslands are adversely affected by establishment of woody tree species and non-native invasive species either due to suppression of disturbances like fire and grazing or conversion of the grassland patches for agriculture, mining, afforestation, etc. These changes may later act as self-reinforcing and can subsequently lead to alterations of the ecosystem’s composition and structure. For the conservation and maintenance of grasslands, several techniques have been used such as grazing, mowing, haying, herbicides, fertilizers and fires. The main purpose of these techniques is to prevent or reduce the establishment of woody plant species further leading to the establishment of climax community. The implementation of these techniques is often constrained by several factors like vegetation type, seasons, accessibility as well as the vertebrate and invertebrate faunal species associated with grassland biomes. Herbicides: The applications of herbicides, both selective (e.g., 2,4-D, MCPP, dicamba, etc.) and non-selective (e.g., gulfosinate, paraquat, glyphosates, etc.), have been found to be quite useful in management of grasslands as they control and prevent the establishment of unwanted plant species. For the management of grassland patches, selective herbicides such as 2,4-D are often used as they target the broad-leaved plants. The utilizations of herbicides have low to negligible impacts on various organisms associated with the grassland ecosystems as the chemical compounds present in herbicides tend to dispel rapidly and gets readily excreted from the bodies of organisms thereby lowering the chances of bioaccumulations and biomagnifications. Fertilizers: The use of fertilizers to increase the yield of palatable species in the grasslands is termed as agricultural intensification. This approach is commonly implemented in the managed grasslands. The main cause behind the shortage of nitrogen, phosphorus and potassium in grassland ecosystems is the removal of vegetations through grazing. Nitrogen is often the limiting nutrient and external applications can increase the forage 31
The Living Terra Firma, Vol.1, No.1, June 2022 productions accompanied with the dominance of grasses. This may lead to prolongation of the grazing periods. The second most limiting nutrient is phosphorus. Addition of phosphorus to the soil also helps in increasing the yield of the grasslands. The application of phosphorus is more effective in the areas where the soil is slightly acidic or neutral as it remains soluble for a longer period. Potassium is another nutrient that is more susceptible to leaching as compared to other cations. Its addition leads to increase in productivity as a portion of the applied potassium is readily absorbed by the plants while the remaining part is lost due to leaching. However, the overall responses of the plant species to the application of fertilizers are determined by both physiological factors (i.e., species-specific) and environmental factors (i.e., temperature, rainfall, soil moisture, soil acidity, etc.). Mowing: This method of is often used in the absence of disturbances like grazing and fire. Although this method is not species specific, it helps in controlling the establishment and growth of woody plants and facilitates the growth of grasses and low prostrate growing forbs. The intervals between subsequent mowing are often objective driven. When mowing is accompanied with haying or silage making (i.e., removal of clippings), it leads to nutrient reduction in the grasslands. However, this approach may fall short as a management technique because the growth of invasive plant species (e.g., Chromolaena odorata), along with native plant species, that are able to complete their flowering and seed maturation before the yearly mowing are also facilitated. Grazing: In the grassland ecosystems, herbivores play important role in preserving the grasslands and maintaining nutrient cycles. Studies have shown that in grassland ecosystems, organic carbon content of soil is higher than that of plants and animals such as grazers and browsers. Nevertheless, the soil nutrients accumulated by the plants for their growth is released back through the processes of grazing and excretion by the herbivores. Through the processes of grazing and browsing, deposition and decomposition of plant materials form a significant part of the nutrient cyclic pathways. However, the release of nutrients back into grassland biomes is also affected by the distribution of herbivores’ excreta and several other processes like leaching, 32
The Living Terra Firma, Vol.1, No.1, June 2022 mineralization and volatilization. Apart from the nutrient cycles, various groups of animals based on feeding habits and dietary preferences such as bulk grazers, concentrate selectors and intermediate feeders also helps in the maintenance of grasslands’ plant species diversity. Fire: It is one of the most common age-old techniques for the management of grassland patches. Prescribed burning has often been used to maintained both natural and managed grassland ecosystems with objectives ranging from reduction or elimination of wildfires to maintenance of ecological diversity. In the absence of fire, there is a trend of gradual increase in heterogeneity within the grassland ecosystems which further decreases over time as invasions by plants lead to biotic homogenization henceforth altering the structures and functions of the ecosystems. Prescribed burnings often help in reduction of invasions by invasive and unwanted woody plant species. Apart from maintaining plant species diversity, burnings also play prominent roles in nutrient cycling. The occurrences of fire rapidly release the nutrients present in the plant materials thereby increasing rates of mineralization and their availability for the plants. In the post burning stage, there is also an increase in soil organic carbon owing to the generation of charred materials from the plant biomass and litters. The production of ashes from plant biomass also enables the release of cations (K+, Ca+, Mg+) into the soil. Although burning of grassland is a widely used old technique however its necessity varies among regions such as compared to arid and semi-arid grasslands, the moist grasslands require more frequent and planned burnings for maintenance. Since time immemorial, humans have depended on grasslands for different purposes like forage and livestock. Presently, with the increase in population, grasslands are often subjected to conversions into settlement areas and agricultural fields. Moreover, changes in climatic conditions such as alterations in rainfall patterns and increase in temperatures facilitate establishment of invasive species and degradation of grasslands. Therefore, in the present scenario, it is important to emphasize on the conservation and management of grasslands because with extensive distributions throughout the world, they can be compared with forests and provide multiple ecological services like nutrient 33

The Living Terra Firma, Vol.1, No.1, June 2022 Chestnut-headed Bee-eater in Gujarat- A Likely Range Extension Rajni Trivedi & P.S. Thakker1 1Email:[email protected] Rajni Trivedi The Chestnut-headed Bee-eater Merops leschenaultia belonging to family Meropidae, is a resident breeder in the Indian sub-continent and adjoining regions. It ranges from the east of India to Southeast Asia. The species is distributed over the Western Ghats south of Belgaum, the Himalayan Terai from Dehradun to east Assam, Orissa, Bangladesh, Ceylon and Burma (Ali, 1972). As per Ali (2012), the species is found in Himalayan foot hills from Kumaon to Arunachal Pradesh, Eastern and Western Ghats, south to Kerala, Bangladesh, Sri Lanka and Andamans. Its IUCN conservation status is Least Concern (LC) (BirdLife International, 2016). A Little About its Natural History: The Chestnut-headed Bee-eater is recorded in habitats including sub-tropical, open wood land regions that are close to wetlands or water bodies. The bird is also common to high lands. The species occurs patchily and locally in fairly well-wooded country intermediate between the moist evergreen and the dry deciduous type forests. Large gatherings collect at nightly roosts in their favourite leafy trees. The bird lacks the two elongated central tail feathers possessed by most of its relatives. The bird is gregarious and nests colonially in sandy banks. 36
The Living Terra Firma, Vol.1, No.1, June 2022 They create a comparatively long tunnel to fit 5-6 eggs. There can be around 10–100 nests in a colony. The bird lay eggs around February–June. Both sexes incubate the eggs. These birds may hunt together in a group, by wheeling flight and catch insects one after another without returning to the perch. Populations that breed along the Himalayan foothills leave the area during winter. Where they go is still a mystery but some evidence suggests that they may be moving to hill forests in South India. Both in autumn and in spring, Chestnut-headed Bee-Eaters are seen in passage in the plains of South, Central and North India, indicating considerable north-south movement (Bird-count India). An animated migration map was created by e-Bird from the observations uploaded by the birders, received by e-bird till the year 2020. Observations, debate and current findings: The second author (Dr. P. S. Thakker) observed 5-6 birds in the year 1980, which were perching on a wire of telephone line located at the back side of the C.N. Vidyalaya school-campus in Ambawadi area of Ahmedabad. The observation note was published in the Newsletter for Birdwatchers (Thakker, 1980). This was challenged by Khachar (1981), who is known to be the authority on birds of Gujarat. Dr. Thakker clarified and the answer was also published in the Newsletter for Birdwatchers (Thakker, 1981). Dr. Thakker was not able to photograph the bird as he did not have camera and he saw the birds during a morning walk. In those days even mobile phones were not available. So, he could not photograph the birds. Later, Monga (1983) reported this bird from Rajpipala forest and Ganpule (2016) included this bird in the checklist of the birds of Gujarat. The first author (Rajni Trivedi) observed and photographed a sizeable flock of Chestnut-headed Bee-eater (Merops leschenaulti Viellot 1817) at Meshwo Reservoir (23º 40´ 19´´ N; 73 º 23´ 22´´ E) near Shamlaji of Sabarkantha District, Gujarat on 28th January 2008. There were more than 35 birds on tree top during morning hours. This was the only occasion he had seen the species in Gujarat and that too in such a big flock. This observation was published in Newsletter for Birdwatchers (Trivedi, 2017). The photograph taken by the author was also published on the cover page of that issue(Fig.1). Recently the author (Mr. Rajni Trivedi) observed the bird on the way from 37
The Living Terra Firma, Vol.1, No.1, June 2022 Ambadungar village to Hamph village in Chhota Udepur district of Gujarat, in the vicinity of Narmada Reservoir at the tri-junction of Maharashtra-Madhya Pradesh and Gujarat border. Though the species is found along the foot-hills of the Himalayas from the northern plains, the only report for the northern plains appears to be from Delhi (Waraich, 2017). Sharma (2018) observed two adult Chestnut-headed Bee-eater at Jhalna Safari Park (26.86 ̊ N, 75.83 ̊ E) Jaipur, Rajasthan, on 29th September, 2018. He was able to photograph the birds. Mr. Sharma knew that the species was photographed four to five times at Jaipur, during almost six weeks in August– September by Mr. Harkirat Singh Sangha. There are no other published reports from Rajasthan. Fig. 2 shows the distribution of the bird in India and Fig. 3 shows the distribution map prepared by Bird Life International across its range. The distribution map prepared e-bird also does not show the distribution of this bird in western states like Rajasthan and Gujarat. Photographers who have uploaded pictures on e-bird are mostly from Nepal and Thailand. Fig. 4 shows the distribution of Chestnut-headed Bee-eater in the country prepared by e-bird. The only two pictures we could find were from Karnataka in India. The photographer is Mr. Raghavendra Pai and pictures were taken from Goilekatte in Udupi district Karnataka on 5th May 2021 and 3rd February 2022. Thus, looking at the observations of the past and recent, the record in Chhota Udepur District confirms an addition of Chestnut -headed Bee-eater to the avifauna of Gujarat.

They are characterized by high altitude, varying degrees of steepness and rocky constitution. They form the ecosystems that may contain different climatic zones within limited distances and altitudes. Mountains, often have assemblage of heterogeneous ecosystems that may exhibit a range of micro-habitats with great biodiversity. This heterogeneity, in turn, leads to good and often unique biodiversity. 42
