About
Located on Redwood Mountain, Whitaker’s Forest is adjacent to Kings Canyon National Park. It lies on gentle to steep slopes in the giant sequoia/mixed conifer forest. Over 215 large giant sequoia trees occur on the property, along with fine stands of second-growth redwood. Mixed conifer forests of both mature and second-growth trees predominate on the west side of the forest and are interspersed with giant sequoia elsewhere.The soils are of granitic origin with the Shaver soil series supporting the mesic giant sequoia and mixed conifer types, while the xeric areas of ponderosa pine and brushland are underlaid by soils of the Holland series. Numerous granitic outcrops can be found on the property.Climatic data was taken on Whitaker’s Forest from 1966 until 1980. Average annual precipitation is about 1092 mm (43″) of rain and about 410 mm (16″) falling in the form of snow. Year-to-year fluctuation can be great, with variations in precipitation from 381 mm (15″)/yr to 1524 mm (60″)/yr recorded. Snowfalls have exceeded six feet in a single storm. Temperatures are moderate, with summer highs in the 80′s F and lows in the 50′s, while winter temperatures are often in the 20′s, never rising above freezing for weeks at a time.
Dominant Usage
Whitaker’s Forest has the oldest permanent plots (established 1915) in California. Studies on vegetation, breeding birds, and resident mammals indicate the rich natural history of the area. Management is focused on facilitating research that improves the understanding and management of giant sequoia forests. Whitaker’s is one of the few places where successful restoration of giant sequoia regeneration via mechanical manipulations has been accomplished. Studies of large tree responses to prescribed fire and mechanical manipulations are active, as are studies of cultural treatments that may advance recruitment of large giant sequoias. Other studies have focused on giant sequoia seedling interactions with mycorrhizal fungi as well as the light requirements for successful seedling establishment.
The primary headquarters area has one large, three bedroom house. Power and propane are available on the site. Camping may be available by researchers upon request. Primitive roads provide access to some of the forest.
