Paunsaugunt Recovery Unit
收藏资源简介:
This is the boundary for the Paunsaugunt Recovery Unit for the Utah prairie dog. The Paunsaugunt Recovery Unit is primarily in Garfield County, with small areas in Piute and Kane Counties. There are 15,620 ac (6,321 ha) of mapped habitat in the Paunsaugunt RU (UDWR 2010a). Approximately 30% of the mapped habitat occurs on Federal lands (Table 2), primarily the Dixie National Forest. The Paunsaugunt RU contains up to 20% of all adult Utah prairie dogs (Table 3). In any given year, 18-38% of the individual adults occur on public lands (Table 5). Spring counts vary from 654 to 2,205 adult prairie dogs (Table 3). The area experienced an increase to 1,153 prairie dogs counted in 2007, but decreased to 835 in 2010 (Table 3). Average prairie dog density in the Paunsaugunt RU was 0.34 prairie dogs per acre from 2000-2007 (USFWS 2007).

本数据集涵盖犹他州草原犬鼠(Utah prairie dog)波恩索根特恢复单元(Paunsaugunt Recovery Unit,以下简称RU)的边界范围。该恢复单元主体位于加菲尔德县,仅在皮尤特县与凯恩县分布有零星片区。波恩索根特RU内已测绘的生境总面积达15620英亩(acre, ac),折合6321公顷(hectare, ha),数据引自犹他州野生动物资源部(Utah Department of Wildlife Resources, UDWR)2010年a版报告(UDWR 2010a)。其中约30%的已测绘生境分布于联邦公有土地(见表2),核心区域为迪克西国家森林。波恩索根特RU栖息的成年犹他州草原犬鼠个体数量,最高可达该物种全球成年种群总量的20%(见表3);任意给定年份中,均有18%至38%的成年个体栖息于公有土地(见表5)。春季普查统计的成年草原犬鼠数量在654至2205只区间波动(见表3),该区域种群数量曾于2007年增至1153只,但在2010年回落至835只(见表3)。2000年至2007年间,波恩索根特RU的草原犬鼠平均种群密度为每英亩0.34只,数据源自美国鱼类及野生动物管理局(United States Fish and Wildlife Service, USFWS)2007年报告(USFWS 2007)。如需获取更多细节,请参阅2012年修订版恢复计划(链接:https://ecos.fws.gov/docs/recovery_plan/1203012_UTPD_RevisedRecoveryPlan_Final.pdf)。
