Neilson Spearhead Nature Preserve
Our Story
A Legacy of Stewardship
A Land with a Long Story
The land now known as the Neilson Spearhead Nature Preserve has a history that stretches back thousands of years. People lived, hunted, fished, and cared for these forests, wetlands, and lakes long for millenia. Their knowledge and stewardship shaped the land and ecosystems that we enjoy today.
The Neilson Family Chapter
In the 1920s, George W. Neilson began purchasing plots along Spearhead Lake. Over the next two decades, the family acquired nearly all of the surrounding land. In 1958, George transferred the final 40 acres to his daughter, Katharine Neilson Cram, who spent summers and later lived on the property full-time. In 1978, Katharine deeded the land to The Nature Conservancy, ensuring its long-term protection.
Modern Stewardship
Today, the preserve is owned and managed by the Mississippi Headwaters Audubon Society (MHAS), a local chapter of the National Audubon Society. MHAS maintains the land, protects birds wildlife, and provides educational programs that connect people to nature, including:
Habitat restoration projects
Citizen science and bird monitoring
Guided walks, camps, and educational events
Protected Forever
The Mississippi Headwaters Audubon Society (MHAS) recognizes the Neilson Spearhead Nature Preserve as an irreplaceable natural treasure worthy of permanent protection. To safeguard its future, on April 6, 1999, MHAS placed the NSNP under a perpetual conservation easement with the Minnesota Land Trust.
This legal agreement ensures that the preserve, still owned by MHAS, will remain protected for generations, regardless of any changes in future land ownership. MHAS provides all management, upkeep, and maintenance for the preserve, covering operational costs and organizing programs and activities in alignment with our bylaws and mission.
Education & Recreation
The Neilson Spearhead Nature Preserve is a living classroom and a place of discovery in every season. Year-round programs invite children, families, groups, and lifelong learners to explore, ask questions, and deepen their connection to the natural world. These hands-on experiences spark curiosity, foster environmental understanding, and help cultivate the next generation of conservation leaders.
Beyond organized programs, visitors can enjoy four seasons of outdoor recreation. Miles of trails wind through forests and wetlands, perfect for hiking, skiing, or snowshoeing, while Spearhead Lake provides opportunities for paddling in summer and ice fishing in winter. Whether learning, exploring, or simply soaking in the quiet beauty of the forest, the preserve lets everyone connect with the rhythms of nature.
Wild & Wonderful
NSNP is home to over 200 documented plant species, including rare and endangered varieties, as well as habitats that support birds, mammals, reptiles, amphibians, and fish. From the haunting call of loons across the lake to the shaded, quiet paths of intact woodlands, the preserve offers a sanctuary for both wildlife and people alike.
Our Commitment
As trustees of this land, we acknowledge that the preserve exists within the homelands of Indigenous peoples who have cared for these waters and forests for millennia. We honor their resilience and continued presence, and we commit ourselves to advancing justice, equity, and respect in our work.
