As several species are added to the list of threatened species every year due to loss of habitat, it is important to understand the role of unmanaged landscape for sustenance of amphibian diversity. In this study, 28 amphibian species were recorded from diferent modifed habitat including 19 new records for Dampa Tiger Reserve (DTR) and its surrounding areas. Further, six species, Amolops indoburmanensis, Limnonectes khasianus, Microhyla mukhlesuri, M. mymensinghensis, Raorchestes rezakhani, and Sylvirana lacrima are new distributon records for the state of Mizoram and out of these, two species, Raorchestes rezakhani and Sylvirana lacrima, are new country records for India. Amongst the recorded species, four species are Data Defcient, two Vulnerable, 14 Least Concern, and eight species are not assessed as per the IUCN Red List. Within the core and bufer areas of DTR, we found that natural perennial stream, puddles, canals, natural ponds, fsh ponds, roadside, primary forest, secondary forest, paddy felds, and human setlement areas are excellent microhabitats for amphibian populaton and need to be conserved for their rich ecological niches. Keywords: Conservaton, microhabitat, protected area, Raorchestes rezakhani, recovery, secondary forest, Sylvirana lacrima.

J TT INTRODUCTION diversity in the modifed ecosystems around the reserve. Change in matured forest lands into modifed landscape through agriculture and other human MATERIALS AND METHODS actvites had resulted in severe loss of biodiversity. Herpetofauna that contributes for over 48% of the Study area terrestrial vertebrates is one of the most threatened The study was carried out in the modifed or groups of animals due to habitat loss, environmental secondary forested areas around Dampa Tiger Reserve, polluton, internatonal trade, and agroforestry (Palacios Mizoram, India. DTR is situated between 23.324–23.413 et al. 2013; Jayakumar & Nameer 2018; Prasad et al. °N & 92.131–92.272 °E and encompasses a core area 2018). As per IUCN, of the 8,126 described amphibian of 500km2 and a bufer zone of 448km2 (Figure 1). DTR species, about 2,202 amphibians are categorized as consists of undulatng and medium hills and slopes of threatened species (Frost 2020). In the past 20 years, mostly bamboo forest. Flat mainlands and patches of the number of Critcally Endangered species has also grasslands with lofy and evergreen run in parallel along increased from 25 in the year 2000 to an alarming 587 the rivers (Pawar & Birand 2001). The climatc conditon species by 2020 (IUCN 2020). Dampa Tiger Reserve in DTR ranges 10–35 °C and receives an annual rainfall (DTR) in Mizoram, northeastern India, is a biodiversity ranging 2,000–2,500 mm between the months of May hotspot that falls within the Indo-Burma region, and is to August (Pawar & Birand 2001). The area remains also greatly afected from shifing cultvaton and other mostly moist due to presence of several small perennial anthropogenic actvites (Pawar et al. 2004). About streams thus forming an ideal habitat for biological 80% of the State’s populaton practces slash and burn assemblages for diferent groups of species. The region method of agriculture that are highly dependent on has a rich and diverse faunal diversity including Malayan forest resources, resultng in clearing of large areas of Sun Bear, Clouded Leopard, Marbled Cat, Golden Cat, matured forest lands every year (Sat & Rinawma 2014). Hoolock Gibbon, Phayre’s Leaf Monkey, King Cobra, and While most researchers have mostly emphasized on Burmese Python (Gouda et al. 2016; Singh & Macdonald the conservaton of faunal diversity in protected and 2017; Gouda et al. 2020a). Previous studies on the matured forest, the importance of secondary or modifed herpetofauna in DTR include works of Pawar & Birand habitats has gained recognized in recent tmes (Dunn (2001), Pawar et al.
