Outline of Discussion ► Environmental and social impacts of deer overabundance ► Description of management area ► Management Plan: Implementation Monitoring and assessment Brief budget and timeline
Proximal Causes of Deer Overabundance
Lyme Disease White-tailed deer appears to be the primary reservoir, but rodents have also been implicated Statistics: Since 1995, the number of Lyme disease cases reported in Fairfax County have risen and in 2007 there were 158 reported cases Loudoun County, which has a large deer population, has the highest per capita incidence of Lyme Disease cases reported in the commonwealth Suggests a strong upward trend in incidence where there are large populations of white-tailed deer
Vehicle Collisions Increased deer populations can become a safety hazard for drivers Virginia had the eighth highest total number of deer-vehicle collisions in the United States over the time period Statistics: During : 4,000- 5,000 deer vehicle collisions occurred resulting in an average property damage of $1,982 per vehicle That is around 9.9 million dollars/year
Ornamental Plant Damage ► Ornamental Plant damage is estimated to be over 1 million dollars annually in Fairfax County ► Planting less palatable plants has been ineffective
Biodiversity Impacts ► Lack of regeneration of canopy trees ► Altered forest shrub layer ► Diminished herbaceous plant species ► Diminished ground and shrub nesting bird species ► Diminished small mammal habitat
Hemlock Overlook ► 426 acres within 5,000 acres of Regional Parkland along the western border of Fairfax County ► Jointly operated with George Mason ► Thousands of acres of private land adjacent to the parkland
Field Observations ► Ample deer sign ► Current deer management: Deer fence located on one property Authorized for sharpshooting
Management Plan: Monitoring ► Monitoring deer populations Spotlight and camera surveys ► Monitoring habitat Exclosures ► Pre and Post Assessment
Management Plan: Implementation ► Herd Reduction Recreational hunts Sharpshooting
Management Plan: Implementation ► Education Program Lectures Education materials Field Education
