Park Begins Environmental Monitoring Project
Sitka National Historical Park has begun an environmental monitoring project designed to sample and analyze various components the air and vegetation. Park users may notice special funnels designed to collect rain water and airborne particles. The 15 black funnels are located in open areas as well as attached to trees in the forest. They are called throughfall passive air samplers and yield data on atmospheric wet and dry deposition of certain compounds, including sulfates, nitrates, ammonium, and hydrogen ions. This effort will be combined with lichen sampling in the park and data from another type of air sampler which is not located in the park. This is a two year project and the samplers will be left out between May and October. They are clearly labeled and all materials related to the project will be removed in October 2009. It is important that the funnels not be disturbed during the sampling process. For more information, please contact Park Biologist Geof Smith at 747-0182.
