Field Notes Sketch

We are outside at Miliken mills pond and are having a break from regular school.

The problems we ran into were using the weed weasel and keeping track of all things we came with.

Its smells like a dead animal in the hot savanna wasting away, I see lushes green trees all around, murky brown water at my feet. I hear the sweet chirping of small birds and the monotonous sound of mosquitos buzzing in circles around my head.

Supporting evidence
Photo of my evidence.

This plant has leaved edges that are fork divided and are not 1-3cm apart.

Photo of my evidence.

Branches are not feather divided, and the plant has less than enough whirls to classify it as Eurasian watermilfoil.

Photo of my evidence.

Plant was submerged, but the amount of whirls did not add up and that and the stem was not a brown type color.

Feathers are not just for birds

Summer field season brings with it all kinds of unexpected challenges - mosquitos,sweaty heat and keeping track of gear and colleagues all add to the adventure. Your keen eye picked up on the forked leaves of the plant, which is a great way to tell if you have eurasian milfoil or not. The ruler in your photo helped with scale reference too. The whorl pattern though does actually match that of eurasian milfoil, so this piece of evidence is a bit less on the mark than your other notes - although good for you to look a that in your observation. Thank goodness it wasn't milfoil and I hope the weed weasel cooperates better next time.
