|Scientific Name:||Cupressus goveniana|
|Infra-specific Taxa Assessed:|
|Taxonomic Source(s):||Farjon, A. 2010. A Handbook of the World's Conifers. Koninklijke Brill, Leiden.|
|Taxonomic Notes:||See under varieties for synonyms.|
|Red List Category & Criteria:||Endangered B2ab(ii,iii,v) ver 3.1|
The assessment of the species as a whole is driven by that of the nominate variety (var. goveniana) as it has the greatest extent of occurrence (EOO) and area of occupancy (AOO) as well as numbers of mature individuals. This variety was assessed as Endangered under the B criterion. The area of occupancy for the species is estimated as 180 km2, with severe fragmentation. The continuing decline in area of occupancy, extent of habitat and number of mature individuals lead to this species being assessed as EN B2ab(ii,iii,v).
|Previously published Red List assessments:|
|Range Description:||This species is found in the California (USA): Mendocino, Sonoma, Santa Cruz, San Mateo and Monterey Counties.|
Native:United States (California)
|Range Map:||Click here to open the map viewer and explore range.|
|Population:||The total population of this species probably consists of fewer than 2,300 mature individuals, perhaps unless the dwarfed individuals with seed cones on the Mendocino “white plains” are also counted as such.|
|Current Population Trend:||Decreasing|
|Habitat and Ecology:||This species is found in chaparral, 'pine barrens', and open pine woodland with Pinus attenuata, P. contorta, P. muricata, P. ponderosa, P. radiata, Pseudotsuga menziesii, Arctostaphylos, Quercus, and Rhododendron, often in groves of up to 1000 trees or more; on sandstone outcrops, white or yellow sandy slopes, and leached, virtually sterile sandy 'hardpan', where it becomes dwarfed. The altitudinal range is from near sea level to 1200 m a.s.l. The climate is of the Mediterranean type with dry, hot summers, but in a narrow coastal strip cooled by frequent fog, and winter rain.|
|Continuing decline in area, extent and/or quality of habitat:||Yes|
|Generation Length (years):||30|
|Use and Trade:||Although introduced by C. T. Hartweg to England in 1848, this species soon turned out to be tender in NW Europe and its cultivation outside collections ceased. In southern Europe it is grown more widely in gardens and parks and a few cultivars are known, some with doubtful affinity to this species.|
|Major Threat(s):||Urbanization, agriculture (conversion of wild land to pasture), and changes in fire regimes are threats to this species.|
|Conservation Actions:||Some (parts of) subpopulations are within protected areas.|
