Biodiversity

by St. Supery on August 13, 2010


What is Biodiversity? The variety of plants and animals and other living things in a particular area or region. Biodiversity is important because plant and animal species interact and depend upon one another for food, shelter, oxygen, and soil enrichment.

St. Supery’s Dollarhide Ranch is a 1500 acre property in the north eastern hills of the Napa Valley. With just over 470 acres planted to vine, the rest of the ranch is unplanted due to specific chemical and physical characteristics of the soils, these habitats are nutrient-poor and not suitable for vinous growth. This unique soil has led to the establishment of a highly specialized and diverse flora. It has been estimated that serpentine endemic plant species represent 10 percent of the California Floristic Province’s endemics.

California and, especially, the location of Dollarhide Ranch is a hotspot of native weeds, plants and insects. Because Dollarhide’s terrain is so diverse with 12 different soil types that make up mini eco-systems for native floral and fauna. Loam, clay and sandstone soils provide ideal growing conditions for our vines. Serpentine soils are mostly left for wildlife and native plants. The property also includes seven lakes that are home to thousands of bass and several species of waterfowl.

Our vineyard manager has also incorporated new plantings to increase the eco-culture at Dollarhide. The ranch is home to over 1000 fruit trees—a part of our commitment to preservation is to plant heirloom and raise heritage varieties of fruit and fowl that existed long ago but are no longer abundant.

The Audubon Society conducts an annual bird count at Dollarhide.
