Summary Author: Dale Hugo
Crabtree Nature Center in Barrington Hills, Illinois has several
ponds this one, the Sulky Pond, is covered with duckweed
fronds, a fast-growing, aquatic plant. It spreads by clinging to the
feathers of migratory birds and can quickly cover a small pond.
It's not pond scum or algae. And yes, the ducks love it. It
provides cover for fish and amphibians, but its role in oxygen
production isn't that useful. Many view it as a pestiferous plant. Cold
weather will quickly kill it off, but next year it'll be back growing
quickly in late summer into the fall.
This scene also shows the branches of a dead oak, marginal water
plants, and the beginning of fall colors. A 1.4-mile (2.25 km) trail
encircles Sulky Pond. Note that Crabtree covers over 1,000 acres of
natural, glaciated terrain that's being restored to its pre-settler
glory. Photo taken October 8, 2020.
