| 説明 | Hood County, Texas, USA9 December 2007 Jim Eidson, Clymer Meadow Preserve Manager for the Nature Conservancy of Texas, visited this area and provides a clear characterization of the plant community represented in photos p216-p224: "...of conservation interest is the ashe juniper-- sideoats/hairy grama (Juniperus ashei -- Bouteloua (curtipendula, hirsuta) woodland *(G2/G3). The herbaceous component expresses as a sparse vegetation within the ashe juniper woodland interstices, and disappears as juniper canopy trends toward closure".It is interesting to note that red-berry juniper is also lightly sprinkled within this same community as well as an abundance of Yucca pallida and what appears to be Yucca rupicola (needs confirmation). Both of these Yuccas are endemic to Texas and have found a secure refuge in this conservation easement. *G2 = 6-20 populations known globally; imperiled and very vulnerable to extinction throughout its range. G3 = 21-100 populations known globally; either very rare and local throughout its range or found locally in a restricted range (e.g., a single state or physiographic region), or because of other factors making it vulnerable to extinction throughout its range. |
