[katie lautar] so, springfield woods is a 100-year-old forest, uh, which we are standing in with a spring this woods wouldn't be here without the community that cares for it. they reached out to us. in 2012, then we started lending our, uh, environmental expertise to helping the community reach its goals in the forest. so, when we work with community leaders in the forest, we treat them like the landowners of that space. and they make all the land management decisions and we support them. prior to that, we had only protected community gardens and pocket parks, and we understood what we needed to know in order to do that. so, we worked with our partners at umbc, and our partners at the u.s. forest service; all helped us to come up with what is it, we would need to look at in order to understand the health of a forest patch. so, we created a forest health research protocol that we since published. we performed this health protocol in over 50 forests. and what we've learned is that baltimore's tree canopy is more than 80 percent native, actually closer to 85 percent and up in some forests. f
