Crown Dieback

Score for 2016:
--/5
Long-Term Trend:
Scores are 
As trees experience stress or decline, they begin to reduce resources to the outermost leaves and branches, leading to crown dieback. This fine-scale measurement allows for a more detailed assessment of the tree's overall vigor and is an early indication of declining health. In any one year, a species may exhibit short-term dieback due to drought or insect damage, for example; however, trends in crown condition provide an early warning sign of forest decline. Canopy dieback is estimated as the percentage of missing foliage from the upper and outer areas of a tree's crown. The current year is scored as a proportion between the long-term mean and the maximum value in the record.
