Dataset Overview

Proportion of trees (greater or equal to 5 inch DBH) with poor crown health of 20% dieback or greater for New Hampshire, New York, and Vermont.

See Full Dataset Documentation


Crown dieback is assessed by visually inspecting the leaves and crown of trees. When trees experience stress, they begin to reduce resources to the outermost leaves and branches, and these areas will die. This fine-scale measurement allows for a more detailed assessment of the tree's overall health and vigor and is an early indication of declining health. While dieback can vary from year to year based on weather or insects, trends over time can indicate more subtle issues in overall health.
