While mild, short-term droughts are not an uncommon event in Vermont, with higher temperatures resulting from continued climate change, we may see more severe or longer-duration droughts. Lack of water, particularly during the growing season, can result in short-term changes in our forests, for example, a tree will halt photosynthesis and growth until there is sufficient water. But droughts can also result in more serious consequences to forests, like lack of a viable seed crop or large die-offs of vulnerable species, locations, or age classes. Seedlings are particularly vulnerable to drought due to their shallow root systems. Further, droughts can increase the chance of forest fire -- to which many of our tree species are not adapted. Insect pest outbreaks can also be more destructive when they occur with or following drought.
