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
