Spread of Lyme Disease in Michigan

New evidence suggests Lyme disease is present in Washtenaw County (MLive, July 29, 2016) and it's not easy to eradicate once it's here.

In a healthy population, female deer can breed as fawns, producing a single fawn at 1 year and continuing through 15 years with 2 to 3 fawns annually.

It is the consensus of natural area managers that controlling excessive deer populations is critical to the long term health and viability of the native ecosystems that these animals are a component of.

The Audubon Society says: "You have to protect yourself, your family, and native ecosystems from the most dangerous and destructive wild animal in North America, an animal responsible for maiming and killing hundreds of humans each year, an animal that wipes out whole forests along with most of their fauna.

Interview with Tom -Rawinski, respected botanist and conservationist, first broad cast on WPKN on August 13, 2014

August 17, 2015, City Council approved the establishment of a deer cull program for the next four years on City of Ann Arbor property beginning in the winter of 2016. In addition, City Council directed city staff to continue to explore an experimental deer fertility control program with the Humane Society of the United States. The deer management program aims to decrease the deer population in order to reduce deer-human negative interactions. City staff will begin work on a culling proposal that will require Michigan Department of Natural Resources approval. Many more details need to be worked out. Communication with residents will continue throughout the cull development process.

From White-tailed deer (Odocoileus virginianus) browse damage in Ann Arbor, Michigan Bird Hills Nature Area, Winter 2015

This survey of 142 tree saplings (less than 2 meters tall) and shrubs in Bird Hills Nature Area shows that 80% have been browsed by deer, and 51% have half or more branches browsed. This level of browsing could interfere with forest regeneration and diminish the flowers and fruit available for birds, butterflies, and bees. Further monitoring would be necessary to track mortality, to reveal whether particular tree and shrub species of concern are browsed in future years, and to assess whether wildflower species are also being heavily browsed.

From Status Report: Deer Population Trends and Impacts in County Parks, February 2014, Washtenaw County Parks and Recreation

Deer are a normal part of the forests and fields of Michigan, but their numbers have grown to unnaturally high levels due to lack of predators. The deer population in Washtenaw County has been steadily increasing over the last 15 years.

Scientists have shown that habitats and deer are most healthy when deer density ranges between 15-20 deer per square mile. Recent aerial studies have shown the density in Ann Arbor to be up to 76 deer per square mile. When the number of deer exceed the "healthy" density level, the plants they depend on begin to disappear. Deer pose a direct threat to the diversity and sustainability of wildlife habitat within Washtenaw County Parks And Recreation Commission natural areas.
  From An Evaluation of Deer Management Options, Northeast Deer Technical Committee, April 2008

In the absence of predation or hunting, this kind of reproduction can result in a deer herd doubling its size in one year. This fact was illustrated on the 1,146 acre George Reserve in southern Michigan where biologists at the University of Michigan have been studying the deer population since 1928. The deer herd grew from six deer in 1928 to 162 deer by 1933. More recently, the George Reserve herd grew from 10 deer in 1975 to 212 deer in 1980.

We have talked to City Council members, met with County Commissioners and the Washtenaw County Parks & Recreation Commission, and we are available to talk to your group.

The WC4EB.org website is set up as an educational site providing information on deer biology, overabundance, and management, especially in urban areas.
