Effects of Logging on Understory Plant Diversity in Northern Hardwood Forests

Project Period: August 1, 1999 through August 1, 2002

Description:

Objective:

The goals of this research project are to: (1) document community patterns of vascular plant diversity in logged and unlogged forests; (2) describe how different species groups, defined by life history attributes, respond to logging; and (3) test hypotheses to explain why certain species groups are negatively affected by logging.

Approach:

Botanical surveys have been conducted on numerous logged stands and adjacent unlogged mature forest stands on the Menominee Indian Reservation in northeast Wisconsin. These include stands that have been subject to different silvicultural techniques ranging from single tree selective harvest to small scale (5-10 hectare) clear-cuts. Ongoing work includes sampling stands before and after logging to more precisely document the type and rate of changes in the plant community and experiments to explain the response of certain species.

Expected Results:

This study should improve understanding of why ant-dispersed species are less common after logging.
