Eurasian watermilfoil: long-term trends in unmanaged populations The Wisconsin Department of Natural Resources conducts and supports a variety of projects that improve our understanding of aquatic invasive species (AIS) and the ways we manage them.
Harvest trends are provided and summarized by Deer Management Unit (DMU). Harvest within each DMU is tracked by the type of harvest (antlered vs antlerless), land type (public vs private), and by weapon type.
The primary objective of Long Term Trend (LTT) Lakes monitoring is to document long-term trends in lake water chemistry. This data set also provides context for water chemistry in other lakes in terms of intra and inter-annual variability.
Population Statistics & Trends Fawn to doe ratios and yearling buck percentages are used to help estimate the deer herd size annually and is the starting point for setting antlerless harvest quotas.
