Understanding the macroinvertebrate fauna of your stream can provide valuable insight into a stream's current state of health and how it recovers from stressors. Stressors such as sedimentation, AMD, excessive nutrients, and acid rain can upset the delicate balance of life in a stream. Sampling techniques, basic macroinvertebrate taxonomy, the effects of various types of pollution, and indicator organisms are just some of the topics to be touched on in a presentation designed for both the newcomer and those who would like to review.


With over 20 years of professional experience in the fields of Benthic Ecology (ecology of bottom-dwelling critters) and Water Pollution, Andy has worked throughout the Eastern half of the U.S. and abroad examining how bottom-dwelling invertebrates in marine, estuarine, and freshwater ecosystems react to and recover from many forms of pollution. Andy has worked in the private sector as well in academia and government and is a former Water Resource/Watershed Specialist in Dauphin County, PA. He is now the Watershed Coordinator at the WPCAMR office in Greensburg, PA.
