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 new web-based mapping application, called the Seedlot Selection Tool (SST), can be used to map either current climates or future climates based on selected climate scenarios.

These resources, including a long-term management calculator, handbook, and factsheet are designed to help practitioners calculate how to budget for lasting conservation outcomes for restoration sites.
