Property Description

Fox River Park (262 acres) is part of the Waukesha County Park System and is located southwest of the city of Waukesha along the Fox River. Habitats include a variety of wetlands (riverine wetlands, ephemeral ponds, and wildlife scrapes), river, and a mature mixed-oak woodland.

Interesting Discoveries

    • State-threatened fish species: Northern Sunfish (Lepomis megalotis).
    • Three new county records:
      • Two daggar moth species (Acronicta spp.), known from northern MN;
      • Second-ever WI record: millipede species (Apheloria virginensis), and previously only collected once before from Milwaukee Co.
    • Very diverse insect community:
        • 135+ Butterflies and moths (not including micromoths still in need of ID);
        • 123+ Beetles including 5 firefly genera.

    • Very healthy forest community: Given that 163 homes border the park, it was encouraging to see a diverse understory with mixed-age trees.
