Shawnee Forest – Heron Pond in the Cache River Natural Area, southern Illinois
This trip will take us into southern Illinois
where we will explore a variety of forest habitats. On first stop
will be the LaRue-Pine Hills Ecological Area located within the Shawnee
National Forest. This areas contains an interesting mix of habitats,
including steep bluffs, mesic and dry forests, hilltop prairies, bottomland
swamp forests, and open ponds. Perhaps the most spectacular feature of
this area is the limestone cliffs that rise nearly straight up (120 m)
from the bottomland swamp forests that border the Mississippi River. These
cliffs provide overwintering sites for the region's poisonous snake fauna,
including the cottonmouth and timber rattlesnake. On Sunday, we will
head east towards the magnificent bottomland and cypress swamp forests
within the Cache River State Natural Area. Some of the bald cypress
trees within this old-growth forest are estimated to be greater than 1000
years of age!
