Imperiled Species

The diversity of freshwater mussels (family Unionidae) in the United States is unmatched in the rest of the world, yet this biodiversity is highly vulnerable, with more than 70% of recognized species considered to be either endangered, threatened, or of special concern. Most species inhabit limited ranges and have small (and/or often unknown) dispersal abilities due to reliance on specific host...

Coastal cactus wren populations have declined in southern California over the last three decades. In San Diego County, this decline has been especially noticeable in the Otay area, which in 2014 supported 14 territories on conserved lands. In the past, there were 25-53 active territories reported for this same area, with the highest estimate in 1992. There is also concern the number of active...

Dwarf wedgemussel is a federally endangered freshwater mussel with a historic range spanning the Atlantic coast. However, populations have dramatically declines over the last 30 years. Therefore, knowledge of current population distribution and abundance is critical to resource managers in order to monitor the species over time and to guide recovery actions. Manual survey efforts (snorkel or scuba...

We are working closely with multiple partners to provide updated information, model potential outcomes, and identify key uncertainties relevant to amphibian and reptile species proposed for listing in the northeast US. We also provide timely science to partners to assist in recovery of listed species, which may involve field research, data analysis, or decision support.

Commercial beekeepers have been bringing their bees to the Northern Great Prairie (NGP) for many decades due to the availability of nectar and pollen-rich plants in abundant grasslands.
