Nature Conservancy

Conservancy as a Mission

In addition to its focus on entrepreneurship, the foundation is committed to environmental conservation and preservation of our property. Many of the environmental standards for the property were developed by our founders and are deeply ingrained in the organization’s culture.

Managing resources to achieve the best possible balance between sustaining the many diverse ecosystems and species and improving their health is both exciting and challenging.

Big Rock Valley’s broad variety of habitats supports an unusually diverse species population. Underway for several years now, species inventories continually uncover new, rare species on the property, many of which are listed as threatened or endangered.

The foundation’s environmental management philosophy guides us to be good stewards and caretakers of the property. We maintain as many self-sustaining, diverse native species populations as practical, giving special attention to listed species. We also give great consideration to the potential consequences of our actions, knowing that any enhancement program to improve the environment or habitat for certain species could have a negative effect on other species — or possible long-term collateral effects for the property.
