Plant functional trait responses to experimental flooding and warming in tundra heath, Yukon-Kuskokwim Delta, Alaska, USA (2024)

This dataset contains species-level measurements of plant functional traits collected from a field experiment manipulating flooding and warming in tundra heath ecosystems of the Yukon-Kuskokwim Delta, Alaska, USA (United States of America), during the 2024 growing season. Traits were measured on all dominant vascular plant species within experimental plots subjected to factorial combinations of flooding and warming treatments. The dataset includes morphological, structural, and leaf economic traits commonly used to characterize plant resource-use strategies. Measurements were collected during peak growing season following three years of treatment application. Data are provided at the species-by-plot observation level and are intended to support analyses of intraspecific trait variation and plant functional responses to environmental change.
