Northern spotted owl data and analysis code, Cascade Range, Pacific Northwest, USA

These data were compiled to allow examination of northern spotted owl territorial occupancy dynamics, especially with regards to the roles played by habitat and competition with barred owl in past and future dynamics. Data are estimates of parameters derived from previous modelling of northern spotted owl territorial occupancy dynamics. These data were collected as part of monitoring of northern spotted owl demography. Associated code allows analysis of these estimates to understand the roles of competition and habitat in recent northern spotted owl declines and to predict the future of northern spotted owl under various management scenarios.

本数据集旨在支持对北方斑点鸮（northern spotted owl）领地占用动态的研究，尤其聚焦于生境以及与横斑林鸮（barred owl）的种间竞争在其过往与未来种群动态中所发挥的作用。本数据集的数据为基于既往北方斑点鸮领地占用动态建模所得的参数估计值。这些数据采集自北方斑点鸮种群统计学监测项目。配套代码可用于对这些参数估计值开展分析，以厘清种间竞争与生境因素在近期北方斑点鸮种群衰退中所扮演的角色，并可基于多种管理情景预测北方斑点鸮的未来种群发展态势。
