USFS Seedlot Selection Tool

The U.S. Forest Service, Oregon State University, and the Conservation Biology Institute have launched a free web-based decision-support tool to help natural resource managers match seedlots (seed collections from a known origin) with planting sites based on climatic information.

The climates of the planting sites can be chosen to represent current or future climates, based on selected climate change scenarios. The tool allows the user to control many input parameters, and can be customized for the management practices, climate change assumptions, and risk tolerances.

The website describes the need and purpose of the tool: Populations of trees and other native plants are genetically different from one another and are adapted to different climatic conditions. Therefore, natural resource managers must match the climatic adaptability of their plant materials to the climatic conditions of their planting sites. Typically, this has been done using geographically defined zones (e.g., seed zones or breeding zones) or seed transfer rules that specify a geographic or climatic distance beyond which populations should not be moved. However, current climate models can now be used to define zones based on climate, rather than geography.
