Arroyo Toad Monitoring and Management

in progress

Project description

The USGS has been studying known areas occupied by toads since 1998 and investigating new localities. USGS will inspect all known areas occupied by toads to identify threats and stressors and in particular identify initial Management actions for implementation. Additionally disease screening and genetic samples will be collected at all sites where toads are detected for future analysis. USGS will hold a workshop for land managers to train them how to implement appropriate management during the breeding and tadpole presence period.
