Wood frog heads for winter cover in South Haven

September 21, 2026

was recorded on 2026-09-20 in South Haven, the most recent vertebrate sighting in the past 30 days. Wood frogs breed in vernal pools in spring and summer, then disperse in fall to overwinter in forested areas. Late September sightings track their movement toward winter habitat in leaf litter and woodland refugia.

Threatened Northern Leopard Frog returns to Cottonwood Creek

July 6, 2026

appeared in Cottonwood Creek on June 24th — a sighting worth documenting given how rare they have become on the west slope. These frogs are skin-breathers, highly sensitive to chemical and sediment contamination, and their presence signals something about water quality. Once common across this region, the species has retreated to fewer and fewer refuges. Yet the creek itself carries a federal impairment listing, and the situation is being actively made worse upstream. **The gravel pit operation ran 226% over its selenium permit limit in the first quarter of this year** — the fourth consecutive quarter it has violated its discharge limits. That leopard frogs have found their way back here, even briefly, is remarkable. Whether they can establish and persist depends now on whether the upstream contamination is brought under control.
