A bird blind is located near the beginning of the sanctuary and loon and goose nesting platforms and bird boxes have been built and erected by members of the Penokean Hills Field Naturalists, volunteers who generously maintain the park for all residents and tourists alike.

Many forms of animal life are being successfully protected in this area. We have a great variety of waterfowl, wading and other smaller birds nesting on site. Mammals such as mink, beaver, otter, and groundhogs live and raise their families in this sanctuary. There are also many species of reptiles and amphibians. Up to a dozen different species of frogs can be heard and seen in the marsh habitat. There are at least 14 species of native orchids growing at Sherriff Creek along with hundreds of other native herbaceous plants, shrubs and trees. A species list is being developed by the naturalists to inventory all wildlife, both plant and animal, on the site.
