Inventorying Bats at Crater Lake National Park
Mohren SR. Inventorying Bats at Crater Lake National Park. 2017
Comprehensive bat species inventories have never been implemented at Crater Lake National Park (CRLA), however there has been a limited amount of bat research conducted within the Park. The only detailed bat survey conducted occurred in 2005 resulting in the Parks initial bat species list. This survey confirmed the presence of 9 bat species in Crater Lake National Park (Duff 2005). In 2016, the Park’s wildlife team implemented a limited amount of acoustic bat surveys in key bat habitat locations to determine the efficacy of implementing a much larger inventory project. Also beginning in 2016, the Park began a project to examine how bat communities respond to a forest restoration project (Mohren et al. 2017). As part of these efforts, three additional species were added to the Park’s bat species list Due to the general lack of information regarding bat species presence and distribution within CRLA this project was developed to fill a much needed gap of knowledge. The overall goal for this project is to improve our knowledge about bat species composition and distribution in the Park in order to provide guidance regarding management decisions while contributing to a larger-scale bat monitoring effort. The objectives include: 1) Determine the presence and absence of bat species in Crater Lake National Park 2) Examine distribution and range of bat species in Crater Lake National Park 3) Provide guidance to guide park management activities to limit negatively impacting sensitive bat species 4) Contribute to ongoing regional and national bat monitoring efforts such as NABat and the Oregon Bat Grid.
