摘要

We identified the habitats where Murree Hills Frog (Nanorana vicina) and Hazara Torrent Frog (Allopaa hazarensis) are most likely to occur in Pakistan, and examined how their occurrence at a particular stream or water body is influenced by site and survey covariates. Although these two frog species are listed as Least Concern in the Red List of Threatend Species by the International Union for Conservation of Nature, major conservation threats to these species in Pakistan include habitat degradation, urbanization, and climate change. We made visits to 69 sites during the 2-y study period (June 2016 to July 2018) in three forest types of Islamabad Capital Territory, District Rawalpindi (Province Punjab) and District Abbottabad, (Province Khyber Pakhtunkhwa), Pakistan. We found Murree Hills Frog at 51% of sites, and Hazara Torrent Frog at 30% of sites. Our logistic regression model explained 78.0% of the variance in Murree Hills Frog occurrence and correctly classified 87% of the cases. Increased elevation and availability of permanent water were associated with an increased likelihood of occurrence of this species. The logistic regression model explained 51.0% of the variance in Hazara Torrent Frog occurrence and correctly classified 70% of the cases. Both species were more likely to be found at sites with Sub-tropical Pine and Moist Temperate Forest compared to Sub-tropical Broad-leaved Evergreen Forest. Our results will help biologists design survey methods for future abundance estimation and population monitoring and will benefit wildlife managers in improving conservation management strategies.
