Forecasting sap flow in birch trees and green-up in the boreal forest of Interior Alaska
April 27 @ 10:00 am to 11:00 am AKDT
Speakers: Jan Dawe, Research Assistant Professor
School of Natural Resources and Extension
Rick Thoman, Alaska Climate Specialist, ACCAP
Two milestones in the progression of spring in boreal Alaska are the start of sap flow in birch trees and later green-up, that time when leaves burst forth from deciduous trees. These events have important implications for the seasonal ecology, society, and even meteorology in the state. This joint presentation by Rick Thoman with ACCAP and Jan Dawe with the OneTree Alaska (UAF Agricultural and Forestry Experiment Station) will highlight ongoing efforts to forecast the timing of these important events and ways this information can be used by Alaskans to plan their spring activities.
