The Build Soil forum is organized by ecoregion. For people in North America, we use the level II EPA ecoregions to determine location categories.
You can use our interactive map to find your ecoregion.
Our hope is that this method of organizing is more helpful than dividing locations by state, because some states vary wildly in terms of climate and ecology. Organizing by ecoregion allows us to group people who will likely have similar experiences with their plants. When people figure out what works in their area, they can share tactics with folks who are working in similar conditions.
Your city may not have its own forum board. We've tried to divide regions by what makes sense ecologically (group members should all experience similar growing conditions) and what's feasible in terms of travel (members of a group should be able to convene without excessive travel).
