Freshwater ecoregions of the world
Did you know that those of us who live near the Flint River in northern Alabama and southern Tennessee are right in the middle of one of the hotspots for aquatic biodiversity? The rivers and streams here have some of the highest biodiversity in the world. Get involved in a river conservation group near you to help protect these unique resources.Freshwater species and habitats are, on average around the world, more imperiled than their terrestrial counterparts. Yet, large-scale conservation planning efforts have rarely targeted freshwater biodiversity. This inattention is due in part to the fact that, compared to better-studied terrestrial taxa, there has been a severe lack of comprehensive, synthesized data on the distributions of freshwater species. Existing worldwide species-level data have covered only the largest river basins or select hotspots, rather than all inland waters. Additionally, these data syntheses have made little attempt to describe biogeographic patterns.
Freshwater Ecoregions of the World (FEOW) is a collaborative project providing the first global biogeographic regionalization of the Earth's freshwater biodiversity, and synthesizing biodiversity and threat data for the resulting ecoregions. We define a freshwater ecoregion as a large area encompassing one or more freshwater systems that contains a distinct assemblage of natural freshwater communities and species. The freshwater species, dynamics, and environmental conditions within a given ecoregion are more similar to each other than to those of surrounding ecoregions and together form a conservation unit.

Flint River Cleanup, Saturday June 7
Slackwater Darter Workshop photos
For these workshops, we gave a brief "in class" overview of the darter, its habitat, and habitat loss in north Alabama.
Next, our volunteers headed out into the field! We took maps that identified possible habitat sites and drove to those locations. Once we found the stream, we simply visually inspected the stream to see if it looked like stream slackwater darters would like. We filled out a form to specify the water quality (is the water clear or full of sediment?), how steep each bank is, an estimated width and depth of the stream, if there was any flooding adjacent to the stream, and whether or not vegetation was growing in the stream. We also used a GPS unit to get an exact location for the site. Here are some of our volunteers surveying a stream:
Here is a FRCA board member documenting one of the more promising sites:
We've managed to visually inspect a LOT of sites during April. If you want to learn how our project is progressing, come to our June meeting! Our intern will give a presentation about this project, our results so far, and what the results mean for the conservation of this threatened species!
