Field Notes
35 people, 11 kayaks, 1 adirondack guide boat, and 5 motor boats! WOW! The Lovell Invasive Plant Prevention Committee (LIPPC) and Kezar Lake Watershed Association (KLWA) joined forces for their first ever Eyes on the Water community-wide effort to monitor lakes and ponds in the Kezar Lake Watershed for invasive aquatic plants. Boats left the landing and returned an hour later with plant samples that were found by bucketscope, snorkel, and by just looking around. Some mucked around the dock and used the weed weasel to reach submersed plants. Upon return, samples were placed in large bins according to key identifying characteristics. We're pleased to report we found no suspicious plants! It was an incredible day on the water with so many people motivated and excited to steward this special lake. The next community-wide effort will be on August 8. Details about this event are in the Field Missions section: http://vitalsignsme.org/kezar. Join us!

Supporting Evidence
Photo of my evidence.
We think this is native watershield because it has oval, unnotched, floating leaves. There is clearly just one leaf per stem (go native floaters!). Stems attach to middle of the leaf (cool).
Photo of my evidence.
There was an interesting thick, clear goo completely encasing this immature leaf. Goo was on undersides of a few mature leaves too. Egg casings? Something else?

Here's a photo of the small population of watershield located on the lefthand side of the boat launch. It was found elsewhere on the lake as well. The goo was only found on the plants near the boat launch.

Comments

You have nice clear pictures for your evidence. But yeah you found the watershield.

Yep, you've found watershield. Right now is high season for most aquatic plants, so there's plenty of this and other species to discover! Most lilies should be in flower around now too. Tho it's hard for me to be certain with just a picture, I think your observation that your goo is an egg casing is a good one.
