    and the abundance of species indicative of fire-maintained open habitats. We found subtle increases in forest species in response to treatments, whereas most native ruderals did not increase significantly in response to the treatments over the long term. The density and competitive effect of the invasive Japanese stiltgrass increased dramatically at both sites in response to the restoration treatments. However, new patches of Japanese stiltgrass established in response to the treatments only at the site with the more recent history of agricultural disturbance. Results suggest that fire restoration treatments were effective in the absence of past agricultural disturbance and in areas lacking Japanese stiltgrass. At sites with a history of agriculture and large populations of Japanese stiltgrass, effective restoration may require eradication of Japanese stiltgrass and reintroduction or augmentation of competitive, native specialists of fire-maintained open habitats.
