''Agave shawii'', with the common names coastal agave or Shaw's agave〔Engelmann, Georg. Transactions of the Academy of Science St. Louis 3:314, t. 2-4. 1875.〕 is a species in the genus ''Agave''. ==Distribution== The plant is native to California coastal sage and chaparral habitats, along the Pacific Coast of northern Baja California state of Mexico and southwesternmost San Diego County of California. The remaining population within California that was confirmed as naturally occurring was located near Border Field State Park, until destroyed by the Federal Government using the Department of Homeland Security's national security policy. It allowed the habitat destruction to build the fence and adjacent cleared open area designed to attempt preventing immigrants illegally entering the U.S. Local native plant ethusiasts and nurserymen acted quickly to remove and rescue as many of the plants that could be saved within a very limited timeframe. Plans are to reestablish the population post development with the wild collected plants. There is another listed population located at Cabrillo National Monument. There is speculation as to whether this is a relict population or was planted there at some time in the past. Genetic studies have not been conducted to determine if the population is related to either the Border Field population or those farther south in Baja California, Mexico. The geographic separation of the two California population sites is approximately 15 miles. There are also approximately three on either side of the border fence next to each other inside the "cactus" garden which is one of the sub-themed gardens of the binational friendship garden of native plants located exactly on the border divide between San Diego and Tijuana inside Friendship Park, total of 6 that were trans-planted from nurseries in March of 2012. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Agave shawii」の詳細全文を読む スポンサード リンク
