Proposed Special Conservation Area (SCA) for the Lakewood

and Laona Districts of the Nicolet National Forest

Jeanette Jaskula, Monica Hauck-Whealton, and Sarah Wielgus

What is the importance of a Special Conservation Area?

To maintain:- undisturbed water, soil, and air- diverse plant and animal communities- habitat for threatened or endangered species dependent on large, undisturbed areas of land- undisturbed reference landscapes

SCA Goals

• Preserve 10,000 acres within the Lakewood and Laona Districts of the Nicolet National Forest as one patch or multiple patches

• Include areas that can be converted to roadless areas

• Include old-growth forest stands and riparian areas

Importance of ForestRiparian Buffers

• Trap sediment and associated nutrients (road construction can be the largest source of sediment in forestry operations)

• Moderate stream temperatures• Provide cover and important organic debris

used as food by stream invertebrates• Reduce the impacts of downstream flooding by

reducing upstream flow

Generalized Forest Types

• Conifers – Pine, Balsam Fir, Hemlock, Cedar, Tamarack

• Lowland Hardwoods – Ash, Elm, Maple

• Upland Hardwoods – Birch, Basswood, Beech, Maple

• Aspen/Birch

• Nonforested areas – sedge meadows, shrub swamps, bogs, marshes
