Northern Coastal Grasslands
California coastal prairie, also known as northern coastal grassland, is a grassland plant community of California and Oregon in the temperate grasslands, savannas, and shrublands biome. It is found along the Pacific Coast, from as far south as Los Angeles in Southern California to southern Oregon. Description California's coastal prairies are the most species-rich grassland types in North America (Stromberg et al. 2002) with at most, 26 species present per square meter. Coastal prairie is also the single most urbanized major vegetation type in the US; 24% of the habitat has been lost to pavement. Wind, salt spray, fire, and grazing are evolutionary disturbances which affected shrubs and tree growth maintaining more open grasslands. In the absence of grazing and/or fire, many areas of coastal prairie are being lost to shrub and tree encroachment. The accumulated organic matter from centuries produce a rich, dark prairie soil (''mollisol''). Coastal prairie often forms a landsc ...

Endangered Species
An endangered species is a species that is very likely to become extinct in the near future, either worldwide or in a particular political jurisdiction. Endangered species may be at risk due to factors such as habitat loss, poaching and invasive species. The International Union for Conservation of Nature (IUCN) Red List lists the global conservation status of many species, and various other agencies assess the status of species within particular areas. Many nations have laws that protect conservation-reliant species which, for example, forbid hunting, restrict land development, or create protected areas. Some endangered species are the target of extensive conservation efforts such as captive breeding and habitat restoration. Human activity is a significant cause in causing some species to become endangered. Conservation status The conservation status of a species indicates the likelihood that it will become extinct. Multiple factors are considered when assessing the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Western Blue-eyed Grass
''Sisyrinchium bellum'', the western blue-eyed grass or Californian blue-eyed grass, is the common blue-eyed grass of California and Oregon in and west of the Sierra Nevada, its range extending south into Baja California. In parts of its range, western blue-eyed grass has previously been classified as ''Sisyrinchium eastwoodiae'', ''S. greenei'' and ''S. hesperium'', but these names are now considered synonyms. ''Sisyrinchium bellum'' grows as a perennial plant in open places where there is some moisture, particularly grassy areas, though it can also be found in woodlands and at altitudes up to . Like other species of blue-eyed grasses that are locally dominant, it is generally known simply as "blue-eyed grass" within its natural range.

Bracken
Bracken (''Pteridium'') is a genus of large, coarse ferns in the family Dennstaedtiaceae. Ferns (Pteridophyta) are vascular plants that have alternating generations, large plants that produce spores and small plants that produce sex cells (eggs and sperm). Brackens are noted for their large, highly divided leaves. They are found on all continents except Antarctica and in all environments except deserts, though their typical habitat is moorland. The genus probably has the widest distribution of any fern in the world. The word ''bracken'' is of Old Norse origin, related to Swedish ''bräken'' and Danish ''bregne'', both meaning fern. In the past, the genus was commonly treated as having only one species, ''Pteridium aquilinum'', but the recent trend is to subdivide it into about ten species. Like other ferns, brackens do not have seeds or fruits, but the immature fronds, known as ''fiddleheads'', are sometimes eaten, although some are thought to be carcinogenic. Description an ...
