New England Leaf Out Project - Special Campaign

Are trees in the New England region leafing out earlier than they did in the past? Do tree species leaf out at different times? These are questions that researchers at Boston University are trying to answer. You can assist them in this aim by tracking the leaf-out of ten deciduous tree species.

Maples, Oaks, and Poplars - Special Campaign

Help scientists and natural resources managers track the “green wave” —the flush of green that accompanies leaf-out –over the course of the spring season, and the spread of seasonal color across the country in the autumn. Observations of individual plants, taken on the ground, can help decision makers develop forecast models and early warning systems for use in forest management and public health administration via pollen forecasting.
