Black River

Black River State Forest encompasses approximately 68,000 acres of pine and oak forest in Jackson County, Wisconsin, representing one of the largest state forests in Wisconsin's system. Established in 1957, the forest lies at the edge of the glaciated central plains, east of the unglaciated Driftless Area. The landscape features dramatic sandstone buttes, castellated bluffs, and the two forks of the Black River winding through sandy plains dotted with wetlands and pine barrens. This vast wilderness provides exceptional opportunities for camping, hiking, hunting, fishing, canoeing, and all-terrain vehicle recreation across its extensive trail networks. Perhaps most remarkably, the forest serves as one of two locations in Wisconsin where elk have been successfully reintroduced after being absent for over 125 years, making wildlife viewing here a genuinely unique experience in the Midwest.

Black River State Forest supports an extraordinary diversity of wildlife across its varied habitats of pine barrens, wetlands, oak forests, and riparian corridors. The forest gained national attention through the elk reintroduction program, with 73 elk released in 2015 and 2016 as part of an agreement between Wisconsin and Kentucky. By 2023, the Black River elk herd had grown to approximately 160 animals, thriving in the aspen, pine forests, and forest openings that provide ideal habitat. Beyond elk, the forest is home to black bears, bobcats, white-tailed deer, beavers, raccoons, and gray wolves that have naturally recolonized the area. The Dike 17 Wildlife Area within the forest provides critical habitat for waterfowl and hosts endangered species including bald eagles, ospreys, the Karner blue butterfly, and the eastern massasauga rattlesnake. Wild turkeys, woodcock, yellow-billed cuckoos, and eastern fox snakes add to the remarkable biodiversity.

The vegetation of Black River State Forest reflects the complex interplay of sandy soils, fire history, and glacial legacy that characterizes this transitional landscape. Extensive pine barrens dominated by jack pine and red pine occupy the sandy uplands, maintained historically by wildfires that swept across the landscape. Oak forests of black oak, white oak, and red oak provide important wildlife habitat and spectacular fall color. The forest understory includes blueberries, sweet fern, bracken fern, and other species adapted to acidic, sandy soils. Wetland communities range from sedge meadows to tamarack swamps, while riparian forests of silver maple, cottonwood, and willow line the Black River and its tributaries. The Castle Mound Pine Forest Natural Area preserves an exceptional example of the region's native plant communities, showcasing the ecological character of this unique landscape position between the Driftless Area and glaciated central Wisconsin.

Black River State Forest showcases a fascinating geological story written in sandstone, sand, and glacial deposits. Protruding above the sandy plains are remnants of eroded Cambrian sandstone, approximately 400 million years old, forming dramatic buttes, knolls, ridges, and castellated bluffs. Castle Mound rises 180 feet above the surrounding plain as a narrow, weathering butte with exposed sandstone cliffs up to 30 feet high along its central backbone ridge. The Wisconsin Glaciation strongly influenced this landscape, depositing vast quantities of sand and creating the outwash plains that characterize the forest floor. After the glaciers retreated but before vegetation established, nothing held the sandy surfaces in place, resulting in extensive sand dunes and blowouts visible today. From the summit of Castle Mound, visitors can observe the former bed of glacial Lake Wisconsin, a massive meltwater lake that once covered this region.

Black River State Forest experiences a humid continental climate with cold, snowy winters and warm, humid summers typical of west-central Wisconsin. Winter temperatures frequently drop below zero degrees Fahrenheit, with annual snowfall averaging 40-50 inches, creating excellent conditions for cross-country skiing, snowshoeing, and snowmobiling on the forest's extensive winter trail system. Spring arrives gradually with wildflowers blooming through May and full leaf-out occurring by late May. Summer brings comfortable temperatures with average highs in the upper 70s to low 80s Fahrenheit, though afternoon thunderstorms can develop quickly across the open landscape. Fall foliage peaks in late September to early October, with the oak forests providing spectacular color against the backdrop of evergreen pines. Annual precipitation averages approximately 32 inches, supporting the diverse forest and wetland communities that characterize this landscape.

The Black River region has attracted human activity for thousands of years, with Native American peoples utilizing the river for travel, fishing, and access to the abundant game of the surrounding forests. The Ho-Chunk Nation maintains strong cultural connections to this landscape. European-American settlement in the 19th century brought the logging industry, which dramatically transformed the forest as virgin pine was harvested and transported down the Black River to sawmills. The city of Black River Falls developed as a lumber town, serving the industry that stripped the original forests by the early 1900s. Following the logging era, attempts at agriculture largely failed on the sandy soils, leading to land abandonment and eventually state acquisition for reforestation. The Civilian Conservation Corps contributed to forest restoration during the 1930s, planting trees and constructing facilities that formed the foundation of today's state forest.

Black River State Forest was officially established in 1957, though state land acquisition in the region began earlier as abandoned agricultural lands reverted to public ownership. The forest developed through decades of careful management aimed at restoring ecological health to lands damaged by logging and failed farming attempts. Reforestation efforts replanted pine across extensive areas of sandy barrens, while natural regeneration restored hardwood forests to other sites. The development of recreational facilities proceeded gradually, with campgrounds, trails, and access roads expanding the forest's public use over time. The elk reintroduction program, initiated in 2015, marked a milestone in ecological restoration, returning a keystone species absent since the 1880s. Today, the forest continues to evolve through management that balances timber production, wildlife habitat, watershed protection, and outdoor recreation, serving as a model for sustainable forestry in Wisconsin.

Black River State Forest offers an exceptional variety of trails and natural attractions across its vast acreage. The Castle Mound Hiking Trail climbs to the summit of this dramatic sandstone butte, providing panoramic views of the former bed of glacial Lake Wisconsin, the unglaciated Driftless Area buttes, and the surrounding forest landscape. The forest features 33 miles of ATV and UTV trails winding through pine forests and sandy terrain, while 48 miles of trails are groomed for winter recreation including snowmobiling and cross-country skiing. The Black River provides outstanding opportunities for canoeing and kayaking through remote wilderness sections. The Dike 17 Wildlife Area offers exceptional birdwatching and wildlife viewing, including opportunities to spot the reintroduced elk herd. Multiple campgrounds including Castle Mound, East Fork, and Pigeon Creek provide bases for exploring this extensive forest, while numerous flowages and streams offer fishing for bass, panfish, and trout.

Black River State Forest provides comprehensive facilities supporting diverse recreational activities throughout the year. Castle Mound Campground offers developed camping with modern amenities, while East Fork and Pigeon Creek campgrounds provide more rustic experiences. Backpack camping sites are available for those seeking wilderness solitude. The forest features multiple boat launches providing access to the Black River and various flowages for fishing and paddling. Designated ATV staging areas serve the extensive off-road trail system. Warming shelters and trail connections support winter recreation. The forest is located near Black River Falls, accessible via Interstate 94 and State Highway 54. Black River Falls offers full services including lodging, restaurants, fuel, and supplies. The forest office provides maps, permits, and current information about trail conditions and elk viewing opportunities. Annual state forest vehicle admission stickers or daily passes are required.

Conservation at Black River State Forest balances multiple objectives including wildlife habitat restoration, sustainable forestry, watershed protection, and outdoor recreation. The elk reintroduction program represents a landmark achievement in large mammal restoration, with the herd successfully established and growing through natural reproduction. Habitat management maintains the mosaic of pine barrens, oak forests, and wetlands that support the forest's exceptional biodiversity. The Karner blue butterfly, a federally endangered species, benefits from management of the oak and pine barrens where its larval host plant, wild lupine, grows. Prescribed fire has been reintroduced to maintain fire-dependent plant communities and reduce wildfire risk. Timber harvests follow sustainable forestry practices that maintain forest health while producing wood products. Water quality protection in the Black River watershed benefits downstream communities and aquatic ecosystems. The forest serves as living laboratory for research on forest ecology, wildlife management, and climate adaptation.
