Field Notes
Purple Loosestrife We investigated in a field area which is also very swampy. The latitude of the swampy area is 43.581752 degrees North. The longitude is -70.702696 degrees West, while the elevation is 97 meters. We believe we did find Purple Loosestrife in this area because our plant is very similar to Purple Loosestrife. One our questions were “Does it have hairs?” because the plant was small and could only find tiny hairs but we weren’t exactly sure. The leaves exactly like leaves (6-10 long, whorled). The stem is square and sort of tiny hairy. I saw people and plants in the field/swamp ,hear crickets and birds, and smell a very stinky swamp. The scientific name for Purple Loosestrife is Lythrum. Purple Loosestrife is a Pollinator (plant), there are 1-10 plants known in the area. When we went back on our latest trip to the pond we discovered that the plant was mostly dead except for 1 part of the plant that looked pretty much eaten.

I think that your field notes and photography was fan I have a concern about your field notes. I request better spelling and grammar. But on the upside, I'm impressed on how you made the description in the field notes. How you made the pictures to match exactly how it shows and puts the image in your head about the descriptions you shared. Well done.
