There is a realization that managed forests and other natural areas in the landscape matrix can and must make significant contributions to biodiversity conservation. Often, however, there are no consistent baseline vegetation or wildlife data for assessing the status of biodiversity elements across protected and managed areas for conservation plann...

An objective multivariate technique is described for identification of individual tigers Panthera tigris from their pugmarks. Tracings and photographs of hind pugmarks were obtained from 23 pugmark-sets of 19 individually known tigers (17 wild and two captive tigers). These 23 pugmark-sets were then divided into two groups, one of 15 pugmark-sets f...

We evaluated gender discrimination of tigers (Panthera tigris) using the shape of their pugmarks. Discriminant Function Analysis (DFA) and logistic regression were used to discriminate gender of 13 known tigers from nine easy-to-obtain pugmark measurements. Both multivariate techniques were quite accurate in discriminating genders; the most accurat...

... However, in Sri Lanka pugmark and scat identification of mammals are an understudied field of research and a rare science these days (Yapa & Ratnavira, 2013;Miththapala, 2018). Pugmark analysis can reveal a lot of information about the animal it belongs to, including direction of travel, age, general physical conditions like size and weight (Sanei et al., 2011;Jhala, Qureshi & Gopal, 2011;Taylor et al., 2016;Thakur, Yadav & Jhariya, 2016;Bhagat, Yadav & Jhariya, 2017;Kabir, Ahsan & Khatoon, 2017), sex (Sharma, Jhala, & Sawarka, 2003;Gu et al., 2014;Singh et al., 2014) and even individual identity in some instances (Sharma & Wright, 2005;Sharma, Jhala, & Sawarka, 2006;Dhande & Gulhane, 2016). Scat or dropping are feces left behind by animals. ...

... However, forested habitats outside of these PAs are not given importance, because of the misnomer that these areas are not rich in biodiversity and are therefore subject to insufficient monitoring and management policies [20,21]. In India, PAs are monitored on timescale basis to understand their effectiveness in conserving biodiversity [22] but the nonprotected (Non-PA) forests or the territorial forests are managed under the working plans with the main objective of production forestry [23]. Therefore, Non-PAs do not have enough remedies and strategies to conserve wildlife species; rather attention is given to scientific ways of enhancing production of timer and carbon sequestration [24]. ...
