The White House Farm Foundation owns and manages Leopold's Preserve, a 380 acre nature preserve protected by a conservation easement held by the Northern Virginia Conservation Trust (NVCT), and open to the public. It is visited daily by community residents, tourists, and educational groups who enjoy its 7 miles of walking trails, interpretive signage, observation platforms and wildflower meadows that showcase the environmental and historic features of the property and surrounding area.


The concept behind Leopold's Preserve originated from the sale and subsequent purchase of the South Market property - a 550 acre tract of land quietly nestled in the Rural Crescent of Prince William county, but planned and approved for industrial and commercial uses. By carving out just a slight portion of the land for a clustered residential community (Villages of Piedmont at Leopold's Preserve), Scott Plein was able to protect in perpetuity the balance of the land, which is enjoyed by hundreds of visitors each week. It is an award-winning model for preservation-oriented land planning and exemplifies White House Farm Foundation's commitment to the environment and ecological systems,  particularly as it pertains to finding a balance between human habitat needs and preserving our natural habitats.
