Rhode Island Department of Environmental Management.
The Rhode Island Department of Environmental Management (DEM) today announced that the longhorned tick, an exotic pest from Asia, has been found for the first time in New England. Working in cooperation with the Animal and Plant Health and Inspection Service (APHIS) of the US Department of Agriculture (USDA), DEM is asking livestock producers and wildlife rehabilitators to observe animals for the presence of the tick.
Serves as a central repository for accurate and spatially referenced biogeographic accounts of nonindigenous aquatic vertebrates and invertebrates. Provided are scientific reports, online/realtime queries, spatial data sets, regional contact lists, and general information for aquatic vertebrates and invertebrates occurring outside of their native range. The geographical coverage is the United States.
These maps were created to help assess impacts on nonindigenous aquatic species distributions due to flooding associated with storms. Storm surge and flood events can assist expansion and distribution of nonindigenous aquatic species through connection of adjacent watersheds, backflow of water upstream of impoundments, increased downstream flow, and/or creation of freshwater bridges along coastal regions. These maps will help natural resource managers determine potential new locations for individual species, or to develop a watchlist of potential new species within a watershed.
