   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.
