Mid-Atlantic Field Guide to Aquatic Invasive Speices

The Pennsylvania State University, Pennsylvania Sea Grant, and the Mid-Atlantic Panel on Aquatic Invasive Species (MAPAIS) recently released a new field guide to aquatic invasive species of the Delaware, Maryland, West Virginia, Virginia, North Carolina, New York, New Jersey, and Pennsylvania region.  This guide contains nearly 100 species, including 20-30 that are new species of concern to the Mid-Atlantic.  Funding was provided by MAPAIS’s Grants Competition.  Be on the look out for MAPAIS’s call for 2017 project proposals soon!

Electronic copies of the Mid-Atlantic Guide to Aquatic Invasive Species (low and high resolution .pdfs) are available on both the MAPAIS and Pennsylvania Sea Grant websites.

“In addition to attracting earthworms, the Barberry creates a perfect, humid environment for ticks. Williams recites the numbers. ‘When we measure the presence of ticks carrying the Lyme spirochete (Borreliaburgdorferi) we find 120 infected ticks where Barberry is not contained, 40 ticks per acre where Barberry is contained, and only 10 infected ticks where there is no Barberry.'”

EbannerCongratulations Charter School of Wilmington Team B for winning the 2016 Delaware ENVIROTHON on April 28!  Although it was a cold and rainy day, about 20 teams of high school students from across the state came out to test their knowledge of environmental topics.  DISC board members, many of whom are heavily involved in planning the competition, were on hand to help with testing- which included sections on invasive plant, insect, and aquatic species.  DISC was proud to sponsor this year’s competition at the GOLD level, in an effort to help raise awareness of invasive species.
