What better way to have welcomed spring than with the arrival of American shad! Shad are an anadromous species, meaning they live in the oceans and migrate into freshwater rivers and streams to spawn. Other well known anadromous species include Striped Bass and Salmon. After spawning, adult shad return to the ocean and the juveniles remain in the freshwater until autumn when they swim to the ocean where they will live for a few years until mature. Shad begin their migration once the river temperatures reach the mid-50s, which typically happens sometime at the end of March. This year the winter was unusually long, so the shad run did not begin until mid April.
Some say grocery store plastic bags are the #1 trash item. Others say plastic bottles, while still others say styrofoam. What is really the number one trash item found?
A short answer to this question is it depends on where you are and how data is collected. Another short answer is that all statements are correct.
When you walk along a tributary to a larger river such as the Anacostia River, you will likely see plastic bags and assume this is our #1 trash item. Plastic bags are easily snagged by vegetation such as tree branches, so they are often seen in and along tributaries. Jim Collier and Cynthia Collier, contractors for the AWS, conducted a survey and wrote a report on trash in 2008 titled ANACOSTIA WATERSHED TRASH REDUCTION PLAN. According to their survey, approximately 47% of trash pieces that were counted in streams were plastic grocery bags-- the #1 category.
Wildlife in the Urban Jungle, the Resilient Red Fox
By: Maryn Foreman, Spring Stewardship Intern
Red foxes are everywhere, maybe even in your backyard! The red fox has become accustomed to an urban habitat by using sheds for nests, eating exposed garbage and mice. Since mice are abundant in cities, the fox offers great rodent control. It has been documented that fox even live longer in urban environments. The coyote and bald eagle are some other natural predators native to this area, but they do not adapt as well to the urban environment, giving the fox a competitive advantage.

Due to the frustration of both AWS and volunteers who have been picking up trash over and over along our river’s shores, I was given a project in 2008 to design and install a trash trap in a small stream called Nash Run that flows through parts of Prince George’s County and the northeast area of Washington, D.C. The goal is to catch the trash around the mouth of the stream before it is carried into the tidal portion of the Anacostia via Kenilworth Marsh especially during heavy rains.
Joining the efforts of many in returning the Anacostia River to an ecologically healthy state, the District Department of the Environment (DDOE) is once again taking the lead on the issue of contaminated sediments, but this time on a much larger scale. DDOE recently announced that it will conduct a remedial investigation and feasibility study (RI/FS) of the sediments in the entire stretch of the Anacostia River!
Green Waters, Nasty Waters
As spring arrives and the accompanying rains begin to fall, our attention might be drawn to all the water flowing over the impervious surfaces and into the storm drains surrounding us near our homes, offices, and everywhere else we look. The storm drains are not much to look at in most places -- but my capstone project, which I am undertaking as part of my position as a Chesapeake Conservation Corps volunteer, seeks to change that in the city of Mt. Rainier, MD.
I first heard of storm drain paintings when I was an undergraduate at the University of Kentucky in Lexington, KY. Colorful patterns and designs started popping up all over the storm drains in downtown Lexington but, beyond a simple artist’s mark, there was no indication of what the project was about.

When you hear about pine barrens you think about New Jersey, but we actually have pine barrens here in the Anacostia watershed! An excellent description of this and other ecosystems present in the watershed can be found in the journal of the Maryland Native Plant Society, Marilandica. For more information click on this link and scroll down to the Spring 2008 issue of the journal and you will find the article entitled "Conservation Priorities and Selected Natural Communities of the Upper Anacostia Watershed" by Simmons et al.
The 225-acre Greenbelt Forest Preserve was officially established in 2003 after many years of struggles by a local group of residents of Greenbelt to preserve this important forests located right north of the beltway.
