# Urban Bat box translocation for Vespertilio sinensis conservation

## TL;DR

This study explores using artificial bat boxes to help Vespertilio sinensis adapt to urban environments and reduce human-bat conflicts.

## Contribution

The study provides empirical data on bat box translocation effectiveness for urban bat conservation.

## Key findings

- Translocated Vespertilio sinensis showed declining use of the bat box over time.
- Activity levels of other bat species decreased initially but recovered the following year.
- Long-term monitoring showed limited success in sustaining bat populations in artificial roosts.

## Abstract

Bats are vital for ecosystem stability, yet their natural habitats are increasingly threatened by urbanization, resulting in marked population declines. While some species have adapted to artificial structures as roosting sites, public fear and prejudice often lead to bat displacement, exacerbating human-bat conflicts. Therefore, exploring feasible solutions to increase bat roosting habitats in urban areas is urgent. On July 25, 2019, 40 individuals of Vespertilio sinensis (20 adults and 20 subadults) were artificially translocated from residential areas in Changchun, Jilin Province, to a new building using bat box. Over the 114-day observation period, the population dynamics of V. sinensis roosting in the bat box exhibited five distinct phases, characterized by a gradual decline in total bat numbers. In the year of installation, activity levels of Pipistrellus abramus and Hypsugo alaschanicus substantially decreased but returned to pre-installation levels the following year. Continuous monitoring from 2020 to 2022 indicated that although the activity levels of V. sinensis increased, not many V. sinensis individuals continued to use the bat box. The results of this study provide foundational data for the establishment of artificial bat roosts in urban areas and offer scientific insights for mitigating human-bat conflicts and promoting harmonious urban ecosystem development.
