CPW Lesser Prairie Chicken ECMC SB181 Shapefile Download

Updated December, 2025 ESTIMATED OCCUPIED RANGE (EOR): An area which encompasses all known seasonal activities within the observed range of the lesser prairie chicken. This does not include historic range. The purpose of this layer is to indicate suitable range within Colorado for the Lesser Prairie Chicken based on suitable habitat present. Lek surveys if area not surveyed; If a lek is identified within 2.2 miles, LPC Lek Site recommendations apply. FOCAL AREAS: Mapped polygons designating high priority habitat, Focal Areas (CHAT 1) as defined in the Lesser Prairie Chicken Rangewide Plan. No Lease (Leasable Minerals only). If leased: Lek surveys if area not surveyed. NSO/NGD (year‐round) within 1.25 miles of an active lek; CSU/SSR in remaining focal area with seasonal timing limits on permitted and authorized human activities from March 1 to July 15; CSU/SSR ‐ Surface density limitation of one pad per section and less than one linear mile of routes per square mile (640 acres); Noise not to exceed 49 dB as measured 30 feet from the source; Structure design that limits perch locations for raptors. CONNECTIVITY AREAS: Mapped polygons designating high priority habitat, Connectivity Areas (CHAT 2) as defined in the Lesser Prairie Chicken Rangewide Plan. Lek surveys if area not surveyed; If a lek is identified within 2.2 miles, LPC Lek Site recommendations apply. LEK SITE: Lek sites typically, although not always, are located on open ridges, grass knolls, or slight rises in topography where vegetation is sparse. Active and Inactive Status (NOT 'Historic' or 'Unknown') LPChicken Leks buffered 1.25 miles. No Lease within 1.25 miles of active lek (Leasable Minerals only). If leased: NSO/NGD (year‐round) within 1.25 miles of an active lek; CSU/SSR ‐ Within 2.2 miles of an active lek with seasonal timing limits on permitted and authorized human activities from March 1 to July 15; Surface density limitation of one pad per section and less than one linear mile of routes per square mile (640 acres); Noise not to exceed 49 dB as measured 30 feet from the source; Structure design that limits perch locations for raptors.更新时间：2025年12月（东部标准时间） 预估占用范围（Estimated Occupied Range, EOR）：指涵盖小草原榛鸡（Lesser Prairie Chicken）观测范围内所有已知季节性活动的区域，不包含历史分布范围。本图层旨在基于适宜栖息地情况，标识科罗拉多州境内适合小草原榛鸡栖息的范围。若区域未经过求偶场调查，则需开展相关调查；若在2.2英里范围内发现求偶场，则需遵循小草原榛鸡求偶场场址相关规范。 FOCAL AREAS（焦点区域）：依据《小草原榛鸡全范围保护计划》划定的高优先级栖息地多边形映射区域（CHAT 1）。仅可租赁矿产资源，不得租赁土地。若区域已被租赁：若该区域未经过求偶场调查，则需开展相关调查；在活跃求偶场1.25英里范围内实施全年非地表扰动/非地质扰动（NSO/NGD）管控；在剩余焦点区域内实施CSU/SSR管控，且对获批及授权的人类活动设置季节性时间限制，时限为每年3月1日至7月15日；CSU/SSR管控要求包括：每平方英里（640英亩）内仅可设置1个钻井平台，且道路总长度不得超过1线性英里；噪声限值为距声源30英尺处不超过49分贝；建筑设计需限制猛禽停留栖息的位置。 CONNECTIVITY AREAS（连通区域）：依据《小草原榛鸡全范围保护计划》划定的高优先级栖息地多边形映射区域（CHAT 2）。若区域未经过求偶场调查，则需开展相关调查；若在2.2英里范围内发现求偶场，则需遵循小草原榛鸡求偶场场址相关规范。 LEK SITE（求偶场场址）：通常（但并非总是）位于植被稀疏的开阔山脊、草甸丘或地势微抬区域。区分活跃与非活跃状态（不包含“历史”或“未知”状态）；以活跃的小草原榛鸡求偶场为中心，划定1.25英里缓冲区。活跃求偶场1.25英里范围内不得租赁土地（仅可租赁矿产资源）。若区域已被租赁：在活跃求偶场1.25英里范围内实施全年非地表扰动/非地质扰动管控；在活跃求偶场2.2英里范围内实施CSU/SSR管控，且对获批及授权的人类活动设置季节性时间限制，时限为每年3月1日至7月15日；每平方英里（640英亩）内仅可设置1个钻井平台，且道路总长度不得超过1线性英里；噪声限值为距声源30英尺处不超过49分贝；建筑设计需限制猛禽停留栖息的位置。
