STARRY STONEWORT UPDATE July 27, 2022.

 

We spent time at the starry stonewort colony site scuba diving to monitor populations. Starry stonewort is an invasive plant that was first seen in Geneva Lake in 2018. These plants are solely male and spread by releasing bulbils, that act as seeds, growing wherever they land. Movement such as hand-pulling is believed to actually stir up these seed-like bulbils and cause more damage by promoting spreading. Through routine dive checks on known population sites we are able to see how these plants are growing. While starry stonewort hasn't gone away, we haven't seen too much growth and believe our native species have been doing a good job at keeping this invasive plant at bay.

SWIMMERS ITCH

How to stay safe this summer

Swimmer's itch is caused by flatworm larvae that can unintentionally latch onto human skin when looking for a waterfowl host and cause irritation or itchiness. They like warm water at around 72°F. When your skin dries, the larvae will burrow into the skin and eventually die, but this typically results in some uncomfortable itchiness.

WAYS TO TREAT
Don't scratch! Use an antihistamine lotion. Don't panic, swimmers itch is rarely serious and will pass in a couple days
