Document Summary
Initial logging caused both short term and long term effects on the diversity in the forests. Secondary effects caused a surge in an otherwise rare disease in moose. Key theme: ecosystem interactions (ie. what affects what) are often very complex and not easily anticipated until after damage has already been done this lecture. We look to continue our understanding of complex interactions within ecosystems. We will focus on more examples of population disturbances within an ecosystem. We will also start to look at industry and its effects on the environment. Two modern methods of logging are currently employed at algonquin. Sadly, each forestation case causes loss of species diversity, and other damages not immediately apparent. Wherever you see elk, you see wolves. 1800"s settlers brought cattle into the yellowstone area. Humans exterminated most if not all wolves in order to minimize loss of cattle. By 1930 no known population of wolf remained in the yellowstone area.
