Green alder ecophysiological data and shrub patch environmental data, Trail Valley Creek, NT
- Description:
- At a low Arctic tundra site (Trail Valley Creek) near Inuvik, Northwest Territories, we measured stem sap flow, stem water potential, and productivity-related functional traits of green alder (Alnus alnobetula) and environmental predictors (water and nutrient availability and seasonal thaw depth) across a toposequence in green alder patches. These data were used to evaluate the role of topographic gradients on upland shrub productivity to understand potential constraints on tundra shrub expansion. Sampled patches of green alder spanned from the top of a hill to the bottom of a slope or drainage channel and were located on south to south-east facing slopes. Eight shrub patches were sampled in 2015 and three were more intensively studied in 2016.
