Help monitor the invasive insect species of adelgids that attack both hemlocks and Fraser firs (the most popular Christmas Tree in North America). Although barely visible to the naked eye, adelgids and their effects on trees can be detected by citizen scientists. Data collection is easy once you have identified an area that contains hemlock or Fraser fir, and you can submit your observations online. Not only are both tree species valued for their beauty, but because of their numbers, they provide wildlife habitat and are an important source of lumber. Your help can help researchers find potentially resistant trees and aid in developing genetically resistant trees to restore forests.
