Field Notes
We were happy because we were outside in the sun. It looks like the invasive species isn't here. We hear leaves rustling and cars passing. We can see wind on water and smell the damp soil. Fall colors are around us. We are not surprised that we didn't find our species because we are in a conservation backyard. We wonder where a good place is to actually find the species? Also, what makes this invasive as opposed to non-native?

This is a GREAT observation from sketch to sneakers! Glad to hear you did not find loosestrife. I do see on the map that it was found close-by, so keep an eye out.
