Awapa Recovery Unit
收藏资源简介:
This is the boundary for the Awapa Recovery Unit for the Utah prairie dog. The Awapa Plateau Recovery Unit encompasses portions of Garfield, Piute, Sevier, and Wayne Counties. There are 27,195 ac (11,005 ha) of mapped habitat in the Awapa Plateau RU (UDWR 2010a). Approximately 68% of the mapped habitat occurs on Federal lands (Table 2). The Awapa Plateau RU contains approximately 10% of all adult Utah prairie dogs (Table 3). In any given year, 30-70% of the RU’s individual adults occur on public lands (Table 4). Spring counts on the Awapa Plateau have varied since 1976 with low counts of 201 adult prairie dogs in 1976 and 1982 and a high count of 1,145 adult prairie dogs in 1989 (Table 3). From 2006-2008, the spring counts showed an increase from 343-769 adult prairie dogs, but decreased to 614 in 2010 (Table 3). Average prairie dog density in the Awapa Plateau RU was 0.06 prairie dogs per acre from 2000-2007 (USFWS 2007).

本内容为犹他土拨鼠(Utah prairie dog)阿瓦帕恢复单元的边界划定说明。阿瓦帕高原恢复单元涵盖加菲尔德县、皮尤特县、塞维尔县及韦恩县的部分区域。该恢复单元内已测绘的栖息地总面积为27195英亩(11005公顷),数据源自犹他州野生动物资源局(UDWR)2010年报告a版(UDWR 2010a)。其中约68%的已测绘栖息地分布于联邦公有土地上(见表2)。阿瓦帕高原恢复单元内的成年犹他土拨鼠个体数量约占该物种成年种群总量的10%(见表3)。任意年份中,该恢复单元内30%至70%的成年个体均栖息于公有土地上(见表4)。自1976年起,阿瓦帕高原的春季种群调查数量波动显著:1976年与1982年的调查最低值为201只成年犹他土拨鼠,1989年的调查最高值达1145只成年犹他土拨鼠(见表3)。2006年至2008年间,春季调查种群数量从343只增长至769只成年犹他土拨鼠,但2010年该数量回落至614只(见表3)。2000年至2007年间,阿瓦帕高原恢复单元内土拨鼠的平均种群密度为0.06只/英亩,数据源自美国鱼类及野生动物管理局(USFWS)2007年报告。更多详细信息可参阅《2012年修订恢复计划》(https://ecos.fws.gov/docs/recovery_plan/1203012_UTPD_RevisedRecoveryPlan_Final.pdf)。
