VTM Data Uncovers Effects of Climate on California's Forests

Posted by: Falk Schuetzenmeister 5 years, 5 months ago

Patrick McIntyre (Ecoengine postdoc) and co-authors present their article, "Twentieth-century shifts in forest structure in California: Denser forests, smaller trees, and increased dominance of oaks" in this month's Proceedings of the National Academy of Science. The authors, which include Ecoengine PIs Maggi Kelly and David Ackerly, used the newly mobilized Wieslander Vegetation Type Mapping data to examine changes in forest structure from the 1930s to 2000s. They discovered that while tree density has increased over the time period there been a decline in forest biomass, which reflects a shift from larger trees to smaller trees. Furthermore, forest composition has moved toward increased dominance by oaks relative to pines. Read the full article here.
