Deer Hunting on Conservation Land Bank Preserves
Both nationally and regionally, researchers have found that elevated deer populations are interfering with tree and shrub reproduction and reducing the abundance of, or eliminating, prairie and woodland wildflowers. Heavy browsing can also lead to dominance by unpalatable or browse-tolerant plant species, including introduced invasive species. By reducing available food resources and altering habitats, these changes can have cascading effects on a wide range of insects, amphibians, reptiles, small mammals, and birds. Locally, deer herbivory of island marble host plants and eggs/larvae is a major mortality factor impeding recovery of this butterfly and negatively impacting other Species of Greatest Conservation Need.
In the absence of natural predator populations, hunting is an important wildlife population management mechanism that helps maintain population levels for the benefit of the hunted species as well as other sensitive species and habitats. It also provides valuable data used to monitor game population health. For many, hunting also provides local, ethically sourced food.
Over the years, Washington Department of Fish and Wildlife (WDFW) biologists have held several public meetings in San Juan County and have advocated strongly for management of the deer population. Many islanders recall the 2021 adenovirus hemorrhagic disease (AHD) outbreak spread quickly through the islands’ high populations. Although this provided a temporary break from over-browsing and likely resulted in increased flowering on some Land Bank Preserves, harvest data suggests deer populations are recovering quickly, especially on Orcas, San Juan and Lopez islands (WDFW, August 2024).
