Prescribed burn followed by herbicide application to be tested as invasive grass species control at San Juan Islands NHP

San Juan Island National Historical Park plans to conduct a prescribed fire on Young Hill between late September and early October 2017, when weather permits. As part of post-burn operations, herbicide will be used in selected areas – less than one acre total – to minimize regeneration of non-native species.

The park has concluded that burning and thinning on Young Hill over the past decade has resulted in a reduction of native species composition and an increase of invasive species, specifically grasses.
