UT DWR Greater Sage-Grouse Occupied Leks 2025

The Utah Division of Wildlife Resources coordinates and conducts leks counts annually to track greater sage-grouse populations. Each spring division staff, university researchers, federal agency personnel, and many others aim to visit each known lek three times to count sage-grouse on their breeding grounds termed “leks”. Leks locations are consistent year to year and counts reflect population numbers. Leks are typically open areas within nesting and brood rearing habitat used by sage-grouse hens. The leks contained in this data set are leks that have been categorized as “Active” meaning that there were two or more male sage-grouse counted in that location in at least two out of the last 10 years. This file is not meant to represent a survey grade location, nor are the intended to be the final authority for habitat delineations, but a guide to areas in the state that should be evaluated for impacts to greater sage-grouse when planning and implementing a project. Leks are represented as points, but are in fact areas of active breeding behavior. Parties should consult with UDWR to determine the precise delineation of habitat for any particular development proposal. If in the review of a proposal or other action, differenced between the maps and the on-the-ground situation become apparent, the on-the-ground habitat delineation shall be the authoritative resource.犹他州野生动物资源局（Utah Division of Wildlife Resources，简称UDWR）每年协调并开展求偶场（lek）计数工作，以追踪大艾草榛鸡（greater sage-grouse）的种群数量。每年春季，该局工作人员、大学研究人员、联邦机构人员及其他相关人员会前往每一处已知求偶场开展三次计数，统计其繁殖领地（即“求偶场”）内的榛鸡数量。求偶场的位置常年保持稳定，计数结果可反映种群规模变化。求偶场通常是大艾草榛鸡雌鸡筑巢及育雏栖息地内的开阔区域。本数据集收录的求偶场均被归类为“活跃”求偶场，即过去10年中至少有2年在该区域计数到2只及以上的雄性大艾草榛鸡。本文件并非用于提供符合勘测精度的位置信息，也不作为栖息地划定的最终权威依据，仅作为该州内相关区域的参考指南——在规划和实施项目时，需对这些区域开展大艾草榛鸡影响评估。数据集中的求偶场以点要素形式呈现，但实际上它们是活跃繁殖行为发生的区域。相关方若需针对特定开发提案确定栖息地的精准划定范围，应咨询UDWR。若在提案或其他行动的审查过程中，发现地图标注与实地情况存在明显差异，则以实地的栖息地划定结果作为权威依据。
