Protecting wildlife corridors is a common management problem in regions of industrial forestry. In boreal Canada, human disturbances have negatively affected woodland caribou populations (Rangifer tarandus caribou), which prefer to function in large undisturbed areas. We present a linear programming model that allocates a fixed-width corridor between isolated caribou ranges and estimates its impact on harvest activities. Our corridor placement problem minimizes total resistance for caribou passing through the corridor, which is protected by a prohibition on all economic activities. We link this corridor placement problem with a harvest planning problem that maximizes the net revenues from harvest minus the cost of building and maintaining forest access roads. We depict gradual expansion of the forest road network over time as a multi-temporal network flow problem. We applied our approach to explore corridor options for connecting caribou populations in the Lake Superior Coast Range, with the Nipigon and Pagwachuan Ranges in the Kenogami-Pic Forest, in northern Ontario, Canada. Our results revealed two locations where corridor placement is cost-effective. Optimal corridor placement depends on the perception of the severity of the impact of roads on caribou populations and decision-making objectives. When the negative impact of roads is perceived to be high and/or maximizing harvest revenues is important, the optimal corridor location is in the eastern part of the study area. However, it is optimal to place the corridor in the western part of the area when the negative impact of roads is perceived to be small or the shortest corridor is desired.

保护野生动物走廊是工业林业地区常见的管理问题。在加拿大北部地区，人为干扰对林地驯鹿种群（Rangifer tarandus驯鹿），它们更喜欢在不受干扰的大区域内活动。我们提出了一个线性规划模型，该模型在孤立的驯鹿范围之间分配固定宽度的走廊，并估计其对收获活动的影响。我们的走廊布置问题最大限度地减少了驯鹿穿过走廊的总阻力，该走廊受到禁止所有经济活动的保护。我们将此走廊布置问题与采伐规划问题联系起来，该问题使采伐的净收入减去建造和维护森林通道的成本最大化。我们将森林道路网络随着时间的推移逐渐扩展描述为一个多时间网络流量问题。我们应用我们的方法探索了将苏必利尔湖海岸山脉的驯鹿种群与 Kenogami-Pic 森林中的 Nipigon 和 Pagwachuan 山脉连接起来的走廊选项，在加拿大安大略省北部。我们的结果揭示了走廊布置具有成本效益的两个位置。最佳走廊布置取决于对道路对驯鹿种群和决策目标影响的严重程度的看法。当认为道路的负面影响很大和/或最大化收获收入很重要时，最佳走廊位置位于研究区域的东部。但是，当人们认为道路的负面影响较小或需要最短的走廊时，最好将走廊放置在该地区的西部。最佳走廊布置取决于对道路对驯鹿种群和决策目标影响的严重程度的看法。当认为道路的负面影响很大和/或最大化收获收入很重要时，最佳走廊位置位于研究区域的东部。但是，当人们认为道路的负面影响较小或需要最短的走廊时，最好将走廊放置在该地区的西部。最佳走廊布置取决于对道路对驯鹿种群和决策目标影响的严重程度的看法。当认为道路的负面影响很大和/或最大化收获收入很重要时，最佳走廊位置位于研究区域的东部。但是，当人们认为道路的负面影响较小或需要最短的走廊时，最好将走廊放置在该地区的西部。
