Once again in 2021 we were able to take advantage of the pandemic, which allowed us to work at the site on 60 days accumulating 462 hours of actual management, and our volunteer mileage in 2021 of 6,653 miles was used to provide the WDNR’s – Bureau of Natural Heritage Conservation with matching dollars to acquire additional funding for their program.

We continued our control of exotic plants as usual from spring through early fall on the Natural Area and on adjacent private lands where we have landowner permission.  During April through July we pulled or treated Japanese Hedge Parsley (Torilis japonica) Spotted Knapweed (Centaurea maculosa) and Garlic Mustard (Alliaria petiolata).  

We continued our efforts again in 2021 to reduce stem densities of three Sumac (Rhus spp.) clones.  We are now four years into our treatment of these clones and we are seeing progress.     We will be taking a different approach to managing these clones in 2022.  We did not take photos of Sumac in 2021.

Wood Turtle Program

We modified three of our existing nest sites in 2021where numerous Common Snapping Turtles were incidentally digging up Wood Turtle eggs while digging their own nests.  The modified design will be used in the future as warranted.  Camera monitoring showed that the sites excluded Common Snapping Turtles but not Wood Turtles.

We installed two new nest sites in 2021.

We also conducted weed management on all 30 nest sites in 2021, 28 were managed four time and the two new sites were managed twice.

The severe drought in much of northern Wisconsin in 2021 appeared to have significantly impacted hatching success.  Monitoring of post-hatched nests showed an increase in embryo mortality.  This was anticipated, but unfortunate.  One of our sites had 10 Wood Turtle clutches laid, but only one nest hatched.  No nest predation was observed at this site.
