Researchers map seasonal greening in US forests, fields, and urban areas

Using the assessment tool ForWarn, US Forest Service researchers can monitor the growth and development of vegetation that signals winter's end and the awakening of a new growing season. Now these researchers have devised a way to more precisely characterize the beginning of seasonal greening, or 'greenup,' and compare its timing with that of the 14 previous years. Such information helps land managers anticipate and plan for the impacts of disturbances such as weather events and insect pests.
