Within the Forestry Sector in Canada and other countries with temperate zone forests, there is much interest in how innovative silvicultural practices could be adapted to maintain, and even enhance, biodiversity in managed forest landscapes. This quest is critical to future productivity (timber supply) and ecological features (biodiversity) of second-growth forests, particularly in an era of uncertainty with respect to climate change. In fact, the forest industry is literally crying out: "Please tell us what we can do, with conventional and innovative practices, to help maintain a future timber supply while maintaining biodiversity and sustainability in these managed forests". There is much rhetoric on what should be done, but a dearth of actual real-world (operational-scale) experiments in innovative silvicultural strategies have been established. A crucial question is: Can we maintain components of biodiversity while growing new forests as quickly as possible? A secondary question is: How do we measure the relative effectiveness of new strategies that enhance timber growth, but maintain habitat for biodiversity?

在加拿大和其他拥有温带森林的国家的林业部门内，人们非常感兴趣的是如何调整创新的营林做法，以维持甚至加强管理森林景观中的生物多样性。这一追求对次生林的未来生产力(木材供应)和生态特征(生物多样性)至关重要，特别是在气候变化不确定的时代。事实上，森林业正在大声疾呼：“请告诉我们，我们可以做些什么，用传统的和创新的做法，帮助维持未来的木材供应，同时保持这些受管理森林的生物多样性和可持续性。”关于应该做什么，有很多花言巧语，但在创新的营林策略中，缺乏实际的(操作规模)实验。一个关键的问题是：我们能否在尽可能快地种植新森林的同时维持生物多样性的组成部分？第二个问题是：我们如何衡量促进木材生长但维持生物多样性栖息地的新战略的相对有效性？
