Welcome to the Global Treeline Expansion Experiment

G-TREE is a globally distributed collaborative project aimed at testing the generality of mechanisms driving treeline position. Using a straight-forward experimental design with seeding and substrate-altering treatments, we will be able to disentangle seed versus substrate limitations on treeline recruitment. Participating researchers from Canada, the United States, and Europe have begun implementing the field experiment in 2013 at arctic and alpine treeline sites. This initiative will provide empirical data on where, and under what circumstances, treeline expansion can occur globally.

This is the home of the Global Treeline Range Expansion Experiment (G-TREE), a global research network.

what is a treeline?

We use the term treeline to describe the ecotone where forest transitions to non-forested ecosystems. In arctic and alpine systems, treelines occur where trees reach the limit of their climatic tolerance. Treeline ecotones are important reservoirs of biodiversity, provide wildlife habitat, and important ecosystem services such as carbon storage. For more information on treelines, take a look at this great overview on altitudinal (alpine) treelines by the Nature Education Knowledge Project.

Who are we?

Our research network includes university and government researchers, post-docs, graduate students, and undergraduates. We hope to engage community participation at some of our long-term monitoring sites in the future. Do you want to participate or learn more? Please contact us!
