Dudleya nesiotica is a very rare succulent plant known by the common name Santa Cruz Island liveforever.
 This dudleya is endemic to Santa Cruz Island, one of the Channel Islands of California.
 This is a squat plant growing in mats on the rocky, exposed ground of the windswept island.
 It is a federally listed threatened species.
Dudleya virens, the green liveforever or bright green dudleya, is an uncommon species of perennial, succulent plant in the family Crassulaceae, native to several coastal southern California and Baja California locations.
Myrsine is a genus of flowering plants in the family Primulaceae.
 It was formerly placed in the family Myrsinaceae before this was merged into the Primulaceae.
 It is found nearly worldwide, primarily in tropical and subtropical areas.
 It contains about 200 species, including several notable radiations, such as the matipo of New Zealand and the kōlea of Hawaiʻ i (the New Zealand "black matipo", "Pittosporum tenuifolium", is not related to "Myrsine").
 In the United States, members of this genus are known as colicwood.
 Some species, especially "M. africana", are grown as ornamental shrubs.
Myrsine juddii is a rare species of flowering plant in the primrose family known by the common name cloudswept colicwood.
 It is endemic to Hawaii, where it is known only from the Koolau Mountains of Oahu.
 There is a single population made up of about 3000 individuals.
 Like other Hawaiian "Myrsine" this plant is called kōlea.
 It is a federally listed endangered species of the United States.
Dudleya gnoma is a rare species of succulent plant in the stonecrop family known by the common names munchkin liveforever and munchkin dudleya.
 It is endemic to Santa Rosa Island, one of the Channel Islands of California, where it is known from one single population containing about 3200 plants.
 The population was discovered in the 1950s and assumed to be a relative of "Dudleya greenei", a plant also occurring on the island which is similar but larger and contains the same number of chromosomes.
 The plant was not described to science until 1997.
 The population is protected from nearby grazing cattle by a fence.
 It still faces threats from deer, which can get past the fence, a limited gene pool, and the fact that a single severe event such as a drought, could eliminate the single population.
 Though rare in the wild, this dudleya is kept in cultivation by gardeners and enthusiasts of succulents, and a cultivar called 'White Sprite' is popular.
Dudleya is a genus of succulent perennials, consisting of about 45 species in southwest North America.
Dudleya stolonifera is a succulent plant known by the common name Laguna Beach liveforever.
 This is a rare plant which is endemic to the coastline of Orange County, California.
 It is known from only about six populations in the vicinity of Laguna Beach, totalling about 30,000 individuals.
 It is federally listed as a threatened species of the United States.
Myrsine linearifolia is a rare species of flowering plant in the primrose family known by the common name narrowleaf colicwood.
 It is endemic to Hawaii, where it is known only from the island of Kauai.
 There are 12 populations remaining, for a total of fewer than 200 plants.
 Like other Hawaiian "Myrsine" this plant is called kōlea.
 It is a federally listed threatened species of the United States.
Rapanea is a genus of plant in family Primulaceae.
 It has often been placed in synonymy with "Myrsine", and many species have been moved to "Myrsine".
The Potrero Ridge Open Space encompasses eastern parts of the Potrero Ridge in the southwestern portion of Newbury Park, CA and the Conejo Valley.
 The open-space area contains a total of 203 acres, and is owned and operated by the Conejo Open Space Conservation Agency (COSCA).
 It is adjacent to the Dos Vientos Open Space in the west, which provides further access to the Santa Monica Mountains National Recreation Area by Satwiwa, as well as the Alta Vista Open Space, Los Vientos Open Space, and Los Robles Trail which leads to Los Robles Open Space in Thousand Oaks, CA and further into Westlake Village.
 Conejo Valley’s longest creek, the Conejo Creek (Arroyo Conejo) runs through the western parts of the Potrero Ridge Open Space.
 Some of the fauna here includes mountain lions, bobcats, coyotes, mule deer, golden eagles, American black bears, and reptiles such as the Western pond turtle and freshwater fish species in the Arroyo Conejo.
 There are more than ten trailheads to access the open-space area, and some of the flora includes oak woodlands, coastal sage scrub and chaparral.
 It is home to a wide variety of rare or endangered plant species as well, including Verity's dudleya, Conejo Dudleya, and Conejo Buckwheat.
