Bishnoi communities are well known for the sacrifices they have made to protect nature. The Bishnois consider trees as religious but they protect the entire ecosystem, that exists in their villages. Animals like blackbucks and chinkaras, and birds like vultures, partridges, peacocks find the Bishnoi village a safe haven. The Bishnois protect them from poachers, allow them to graze freely in their farmlands; keep stone vessels near their home, that are always filled with water; and even hang water-filled pots from the branches of trees for the birds to drink from
So, the correct answer is 'Bishnois'
