Select one of the Data Layer overlays to show areas matching the areas you selected.
The highlighted areas on the map indicate areas matching all three parameters, when compared to the combinations present in your selected area.

Welcome to the climate match toolkit for PlantRight's Plant Risk Evaluator (PRE). This is designed for PRE users — plant scientists involved in the development, production, and distribution of horticultural plants, to quickly and consistently answer PRE's four climate-related questions.
This toolkit is a collaboration between GreenInfo Network, PlantRight, Cal-IPC, and Agricultural Sustainability Institute at UC Davis. Funding is provided by Sustainable Conservation. Horticultural growers or plant scientists interested in promoting exclusively non-invasive plants for regional markets are invited to join our growing PRE community. It's free.

The global match data layer (PRE Combined) shows areas in the world where three variables (Plant Hardiness, Ecozones, and Precipitation) all match the conditions found in selected search geometry.
The global match data layer (PRE Combined) was generated by merging together three input datasets (Plant Hardiness, Ecozones, and Precipitation) into a single three-band raster layer. To combine these three different datasets, they were each converted to raster format with the Precipitation dataset used as reference for cell size and extent. The three layers were combined into a single three-band raster layer using the Composite tool in Desktop ArcMap. The three-band raster was exported to .tif format for use in the web map. To generate lookup tables for the unique three-value combinations per state and ecoregion, the combined raster data was converted to point format, then joined with the states and ecoregion layers (Spatial Join tool) to generate summary tables.

To use the map, select an area on the left or by clicking the map to see global matches. You can select more than one area, and clicking an area you've already selected will deselect that area.
Use the buttons below the area lists on the left to download a report, copy a shareable link, or see specific match conditions.
The map controls on the right allow you to view the different datasets that make up the climate match, adjust data layer transparency, quickly zoom to the United States (home icon) or the globe (world icon), and view legends for selected data layers.
Each data layer will show only those areas that match the source region you selected, but for USDA hardiness, Precipitation, and Ecozones, you will still see areas colored by the appropriate values as shown in the legend.
