The Turtle Breeding and Rehabilitation Centre cov- ers 3.75 ha and houses various species of turtles. Before the onset of the project, the Sarnath facility had two functional enclosures (E-1 and E-2; Fig. 2) and a non-functional enclo- sure (E-3). In 2017, with the collaboration of the Wildlife Institute of India, the center was brought under the aegis of the Biodiversity Conservation and Ganga Rejuvenation (BCGR) Project to be managed by Component IV-Rescue and Rehabilitation. Initially, the facility housed multiple turtle species of dif- ferent age classes in the same enclosures, which resulted in injuries because of infighting. All animals were fed an exclu- sively vegetable diet without regard to age class or whether they were naturally carnivorous, omnivorous, or herbivorous. The limited number of basking spots led to compromises in thermoregulation and unrestricted public entry created stress for reclusive species unable to find hiding spots. The center also lacked facilities to monitor hatchlings. The water was changed almost daily, with waste water (approx. 5 million liters every day) dumped in an open area. The ponds within the enclosures were devoid of natural elements and arrange- ments for seasonal temperature fluctuation were limited, compromising the thermoregulatory behavior of the turtles. Sanitation and hygiene for the enclosures as well as ponds were not considered before the onset of the project.

The River Ganga, which flows through the entire north-ern plains of India, is considered one of the most sacred

Indian rivers, but it is not bereft of its share of threats and conservation concerns. A Turtle Sanctuary was declared at Varanasi, Uttar Pradesh in 1989 as part of the Ganga Action Plan, followed closely by the establishment of the Turtle Breeding Facility at Sarnath, Varanasi. The hope was to curb the rate at which the population of the Ganges Soft-shelled Turtle (Nilssonia gangetica) was declining and to provide head-starting facilities for turtles intended for release into the river. One prime objective of the Ganga Action Plan was for these large carnivorous turtles to serve as a biological control for pollution along the riverbanks caused by partially cre-mated bodies deposited in the river at Varanasi. The Turtle Breeding and Rehabilitation Centre, Sarnath, is situated on the outskirts of Varanasi (Fig. 1). Given cur-rently prevailing threats to fresh water turtle numbers and the sizable number of displaced animals and confiscations, che-lonian recovery stations like the Kachua Punarvaas Kendra (Turtle Breeding and Rehabilitation Centre) play a vital role in conservation management programs. The Turtle Breeding and Rehabilitation Centre cov-ers 3.75 ha and houses various species of turtles.

have been enriched with species-specific upgrades. In accor-dance with the ecology of the species, new furnishings and upgraded bio-filtration and aeration systems have been incor-porated. Diets have been adjusted to match the feeding habits of each species. The enclosures are covered on all four sides with green shade drapes (Fig. 3) to minimize interaction with humans, whereas the top remains exposed to natural sun-light for basking. Additional enclosures have been added to

accommodate age-class requirements. These include a juve-nile enclosure (Fig. 4) that holds hatchlings for a month to allow careful monitoring. A part of the previously non-functional E-3 was renovated and extended to accommodate large turtles weighing 20–50 kg (Fig. 5). Landscaping inside the enclosures includes logs for basking, aquatic macrophtyes for cover and food, water circulation units, hides, shades, and haul-out mats to improve aesthetics, provide the animals with better opportunities to exhibit natural behaviors, and reduce the stress of captivity (Figs. 6 & 7). Live fishes have also been incorporated for the carnivorous and omnivorous species for

the same purpose. For sanitation and hygiene of the enclo-sure, 20% of the total water volume is changed every three days, ponds are scrubbed clean once a month, and the prem-ises are cleaned regularly. Maintaining optimal water temperatures in captivity is challenging. Temperatures drop to as low as 4–10 °C dur-ing winters and rise to as high as 40–48 °C during summers. During winters (November to mid-February), enclosures are insulated with thick plastic sheets and water is heated to maintain ambient temperatures around 29–30 °C (Fig. 8). During summers, thatched shades and shrubs (Fig. 9) limit direct sunlight but still provide sufficient basking sites and roofs of enclosures are covered partially with thatch to prevent over-heating of water. With prior permission from the Uttar Pradesh Forest Department, turtles in the center are released when declared Fig. 9. Thatched shades and small trees in the enclosures provide shelter

during the heat of summer.

fit to survive in their natural habitat (Fig. 10), which helps to sustain viable populations in the wild. Because freshwa-ter turtles are important components of aquatic habitats, the Rescue and Rehabilitation Centre at Sarnath plays a vital role in ecological sustainability (Fig. 11).

Forest Department for their support and for granting permis-sion to carry out the project. We also extend our gratitude to Dr. V.B. Mathur, Director; Dr. G.S. Rawat, Dean, FWS; Dr. Bitapi Sinha, Research Coordinator; and Dr. Ruchi Badola, Scientist-G of the Wildlife Institute of India, for their extensive support. We also thank our field assistants, Brijesh Maurya, Ishu Verma, Pyarelal, Pintu Yadav, and Jyoti Singh, for their hard work and support for the refurbishment of the centers.
