AUGUSTA, Maine — A new report from the Maine Department of Agriculture, Conservation and Forestry has determined that there are 145 different species of spiders on and around Mount Katahdin, including five that had not previously been found on the mountain.
According to a Department of Agriculture, Conservation and Forestry press release, the report published by the Maine Forest Service is based on scientific research done by scientists Daniel T. Jennings, Charles D. Dondale and James H. Redner. The report provides specific information that can be used to provide a baseline for studies on habitat and recreational use effects in the park.
According to the release, none of the 145 species of spiders was poisonous — Maine has no native poisonous spiders. The five previously unidentified spider species are unique to the North American alpine environment found on Katahdin. Some of those spiders have also been found on Mount Washington in New Hampshire and in Quebec.
Some of the Katahdin specimens are available in the Maine Forest Service insect collection; others are being stored at the Harvard Museum of Comparative Zoology.
According to the news release the Maine Forest Service frequently publishes technical reports on a variety of scientific subjects ranging from invasive insects to silviculture as a way to support Maine landowners, forest managers and business people.
