Overview

The Brook Floater (Alasmidonta varicosa) is a stream-dwelling freshwater mussel native to the Atlantic Slope of the United States and Canada that has experienced large population declines over the last 50 years and is at high risk of extinction. This project will focus on strategies for achieving conservation for Brook Floater through multiple objectives:

  • We will develop standardized surveys that will be conducted throughout partnering states to estimate abundances and predict occupancy of Brook Floater.
  • We will develop species distribution models from the results of surveys from partnering states to inform future surveys and understand the habitat needs of Brook Floater.  
  • We will develop propagation methods and build capacity for Brook Floater propagation throughout the range to aid in for population restoration.
  • We will use structured decision making to focus monitoring design at the state and regional scale.
  • We will work with state partners to develop consistent and coordinated monitoring at the state and regional scales to understand status and changes in Brook Floater populations throughout their range.
