Invasive species are expected to increase in the dry calcareous forest, woodland, and glade ecosystem.

Invasive species are also common in this forest ecosystem, and climate change is expected to promote establishment and growth of invasives, resulting in increased competition with the high number of rare native plants in this ecosystem. Increases in invasive species such as cheat grass, stilt grass, and bush honeysuckles could increase fire fuels in this type, leading to potentially more intense fire when it does occur.
