Hi Joe!
In our facilitation, we often use participatory-mapping-esque exercises where stakeholders can share their priorities, concerns about a proposal, proposed changes, or their knowledge of a landscape (e.g., social trails here, trash dumping here, etc.). We very often do this for recreation planning exercises, but we have done this in other contexts as well. We've done this in-person with printed maps, sticky dots, and printed datasheets for folks to fill out or online using virtual platforms like Miro, Jamboard, and ArcGIS Online.
I also recently went down a participatory mapping rabbit hole and have some other resources to share:
I have also noticed that many of the resources on participatory mapping focus on international efforts. It would be great to develop one that is more specific to collaborative conservation in the US.
