“The Seedlot Selection Tool (SST) is a web-based mapping application designed to help natural resource managers match seedlots with planting sites based on climatic information assuming that plant populations were in the past adapted to their local climates. The SST can be used to map current climates or future climates based on selected climate change scenarios.” It is a collaboration between the US Forest Service, Oregon State University, and the Conservation Biology Institute.
This news article describes a recent study that utilized extensive tree ring data to assess the likely impact of climate change on forest growth rates throughout North America. The abstract for the research article is available here.
Major forecast findings included:
Negative impacts on forest growth rates in the interior west and positive impacts on forest growth along western, southeastern, and northeastern coasts
Shifts in sensitivity (how tree growth responds to climate) offset the positive effects of warming on high-latitude forests — no evidence for continued ‘boreal greening’
Increases in water-use efficiency due to CO2 fertilization where insufficient to reverse projected growth declines across much of North America
This report is a national assessment of peer-reviewed scientific research on the impacts of drought on U.S. forests and rangelands. It includes information about the response of forest physiology, insect and fungal pathogens, and forest biogeochemistry to current and future drought, as well as impacts of increasing drought on forest dynamics, structure, diversity, and management.
