Locating potential historical fire‐maintained grasslands of the eastern United States based on topography and wind speed

open access: yesEcosphere, 2022
Historically, grasslands with limited tree presence were embedded in a matrix of predominantly open oak and pine forests in the eastern United States. These open ecosystems mostly have been lost to other land uses, particularly agriculture, and also to ...

Weed Control as a Rationale for Restoration: The Example of Tallgrass Prairie

open access: yesEcology and Society, 2003
The potential weed control benefits of ecological restoration are rarely cited and largely unstudied. Nevertheless, the nature of many restoration target communities, i.e., diverse, late-successional communities, suggests that restoration may control ...
