## The high latitude transects span significant variation in several environmental variables and provide a network for improving our understanding of controls over vegetation dynamics, carbon dynamics and water/energy exchange in high latitudes

**The high latitude transects span significant variation in several environmental variables and provide a network for improving our understanding of controls over vegetation dynamics, carbon dynamics and water/energy exchange in high latitudes**
**Objective of studies by High Latitude Transects Working Group:  Evaluate how vegetation dynamics, carbon dynamics, and water/energy exchange are related to environmental variation spanned by the network of high latitude transects (McGuire et al., in press)**
