Trees and Morels share an important relationship. The more we learn about burn morels the more we seem to learn about trees too.

This map offers tree species to select from and shows 2021 or 2022 burns for hunting in 2023. Please give this a minute to load – there is a lot of data contained in the map. Scroll down below map for detailed information on how to use it!


Some tips for using this map:

Each tree type has multiple species underneath it.

  • you must select a tree type AND at least one species
  • There is a lot of data in this map… you may need to wait a few seconds for your map to render.
  • if you see a species called “spp” it will include all the species in that tree type.
    • Basal Area” is the best choice generally (Basal area is a measurement of how much of an area is taken up by tree steps.  It is based on a sum of all the tree diameters, at breast height (DBH).
    • “Quadratic Mean Diameter” (QMD) give more weight to larger trees; use this if you are looking for forests with bigger trees.
    • “Frequency” is the frequency of occurrence of the indicated species in the given study area, or, the % chance you will find that tree species in the given sample size, which is likely an acre. 
    • Stand Density Index” is more complex and is used by foresters to tell when to thin forests.
  • if you expand the Basal Area (with the little carrot) you will get a color key.
  • click on the three elipse ot the right of the tree type to “select visibility range” and reduce the opacity so you can see the basemap under the trees.
