Updated December, 2025 MIGRATION CORRIDORS: A specific geographic area that facilitates movement between seasonal ranges and receives higher use than the surrounding landscape, relative to herd or population use, and loss of which would disrupt migration. Starting in 2023 and moving forward, Brownian bridge model of movement data, where available, will be included in this layer. This represents a change in the methodology from how these data had previously been generated. CSU/SSR ‐ Surface density limitation of one pad per section and less than one linear mile of routes per square mile (640 acres). If pad or route density cannot be achieved or maintained, implement offsite mitigation to offset functional habitat loss. PRODUCTION AREA: That part of the overall range of elk occupied by the females from May 15 to June 15 for calving. (Only known areas are mapped and this does not include all production areas for the DAU). TL ‐ No permitted or authorized human activities from May 15 to June 30; CSU/SSR ‐ Surface density limitation of one pad per section and less than one linear mile of routes per square mile (640 acres). If pad or route density cannot be achieved or maintained, implement offsite mitigation to offset functional habitat loss. SEVERE WINTER: That part of the range of a species where 90 percent of the individuals are located when the annual snowpack is at its maximum and/or temperatures are at a minimum in the two worst winters out of ten. The winter of 1983-84 is a good example of a severe winter. TL ‐ No permitted or authorized human activities from December 1 to April 30; CSU/SSR ‐ Surface density limitation of one pad per section and less than one linear mile of routes per square mile (640 acres). If pad or route density cannot be achieved or maintained, implement offsite mitigation to offset functional habitat loss. WINTER CONCENTRATION: That part of the winter range of a species where densities are at least 200% greater than the surrounding winter range density during the same period used to define winter range in the average five winters out of ten. TL ‐ No permitted or authorized human activities from December 1 to April 30; CSU/SSR ‐ Surface density limitation of one pad per section and less than one linear mile of routes per square mile (640 acres). If pad or route density cannot be achieved or maintained, implement offsite mitigation to offset functional habitat loss.2025年12月更新 迁移廊道（Migration Corridors）：指一类特定地理区域，可助力动物在季节性活动范围间移动，相较于种群或群体的整体利用程度，该区域的被利用强度高于周边景观，其消失将干扰动物迁徙活动。自2023年起，若可获取移动数据，将采用布朗桥（Brownian bridge）模型生成该图层数据，这相较于此前该类数据的生成方法存在方法学变更。 CSU/SSR标准：地表密度限制为每分区1个作业平台，且每平方英里（合640英亩）内的作业线路总长度不超过1线性英里。若无法达到或维持上述作业平台与线路密度，则需实施场外减缓措施，以抵消功能生境损失。 生产区域（Production Area）：指雌性马鹿在5月15日至6月15日产崽期间占据的整体活动范围中的部分区域。（仅将已探明区域进行制图，本图层未涵盖DAU的全部生产区域） TL管控要求：5月15日至6月30日期间，禁止任何经许可或授权的人类活动； CSU/SSR标准：地表密度限制为每分区1个作业平台，且每平方英里（合640英亩）内的作业线路总长度不超过1线性英里。若无法达到或维持上述作业平台与线路密度，则需实施场外减缓措施，以抵消功能生境损失。 严重冬季栖息地（Severe Winter Habitat）：指当十年中最恶劣的两个冬季的年度积雪达到最大厚度、或气温达到最低值时，物种90%的个体集中分布的活动区域。1983-1984年冬季即为典型的严重冬季。 TL管控要求：12月1日至次年4月30日期间，禁止任何经许可或授权的人类活动； CSU/SSR标准：地表密度限制为每分区1个作业平台，且每平方英里（合640英亩）内的作业线路总长度不超过1线性英里。若无法达到或维持上述作业平台与线路密度，则需实施场外减缓措施，以抵消功能生境损失。 冬季聚集区（Winter Concentration）：指在十年平均情况中的五个冬季内，同一时期内该区域的种群密度较周边冬季栖息地的种群密度至少高出200%的物种冬季活动区域。 TL管控要求：12月1日至次年4月30日期间，禁止任何经许可或授权的人类活动； CSU/SSR标准：地表密度限制为每分区1个作业平台，且每平方英里（合640英亩）内的作业线路总长度不超过1线性英里。若无法达到或维持上述作业平台与线路密度，则需实施场外减缓措施，以抵消功能生境损失。
