The forestry industry is one of the fundamental pillars of the Canadian economy, and is a strong link to our past development. However, one of the strengths of the modern industry is the wide adoption of forest certification, which ensures for the buyers that the forests are managed in a sustainable manner. In the past there was a strong focus on what was going on in an individual forest stand, but as management overall improves, there is an increasing focus on the landscape level. While the effect arrangement and amount of unharvested forest has been examined for several animal species, it has been little considered for most plant species as they are generally not considered as dispersal limited in the boreal forest. However, many bryophyte (moss and liverwort) species are potentially dispersal limited, particularly those with specific characterisitcs, for example infrequent reproduction. This project aims to fill this knowledge gap by examining the influence of landscape characteristics on bryophyte community composition, species dispersal and genetic diversity. With these results, we will be able to develop minimum threshold values of habitat quality, amount and organisation across a forest landscape. Via the participation of industry and governmental partners, these thresholds can be integrated into forest management, facilitating forest certification and Canadian forest products brand strength on the international markets.

林业是加拿大经济的基本支柱之一，与我们过去的发展有着紧密的联系。然而，现代工业的优势之一是广泛采用森林认证，这可以确保买家以可持续的方式管理森林。过去，人们非常关注单个林分的情况，但随着管理总体改善，人们越来越关注景观水平。虽然已经检查了几种动物物种的未采伐森林的影响安排和数量，但很少考虑大多数植物物种，因为它们通常不被认为在北方森林中的传播受到限制。然而，许多苔藓植物（苔藓和地钱）物种的传播可能受到限制，特别是那些具有特定特征（例如繁殖不频繁）的苔藓植物。该项目旨在通过研究景观特征对苔藓植物群落组成、物种传播和遗传多样性的影响来填补这一知识空白。有了这些结果，我们将能够制定整个森林景观的栖息地质量、数量和组织的最小阈值。通过行业和政府合作伙伴的参与，这些门槛可以纳入森林管理，促进森林认证和加拿大林产品在国际市场上的品牌实力。
