然而，这个国家仍然有数百万英亩的土地适合海狸居住，在目前的诱捕法和禁渔期下，海狸正在逐渐增加。至于未来，将海狸视为该地区最宝贵的自然资源之一并非不合理。需要进行良好的管理，以长期维持这一资源。要想管理成功，我们需要知道的两件事是，现有的食物和水可以养活多少海狸，以及我们如何管理这些资源，使它们满足动物的需求。为了改善管理的基础，作者在1936年秋天开始研究海狸与森林的关系，以期找到以下问题的答案：

As to the future, it is not unreasonable to visualize the beaver as one of the most valuable natural resources of the region. Good management will be needed to maintain this resource on a permanent basis. Two of the things we need to know to make a success of management are how many beaver can be supported on the food and water available and how we can manage these resources so that they will meet the needs of the animals. In order to improve the basis for management, the writer in the fall of 1936 began a study of beavers in relation to the forest with the view of finding answers to the following questions:
