The Castle Hill and Walnut Mountain projects complement TNC's ongoing work to protect water quality in the Rivanna River watershed, where TNC is working to preserve forests, restore streams, retire development rights and maintain natural flows and safe drinking water.
Former owners Ray and Stewart Humiston donated a conservation easement to TNC ensuring that development will be permanently restricted on the 1,203-acre farm. They also donated 345 adjoining acres that, combined with 33 acres donated by a neighbor, created TNC's Walnut Mountain Preserve. The landowners donated another conservation easement to Albemarle County on these 378 acres. Together, these easements enhance Albemarle’s efforts to preserve its rural heritage.
