Anatomical anomaly data for Alnus alnobetula and Salix spp. collected from the Inuvialuit Settlement region, 2022-2024

This dataset contains categorical records of blue ring and frost ring anomalies identified in cross sections from sampled living tundra shrubs, Alnus alnobetula and Salix spp., from riparian sites along a latitudinal transect. Data were collected in the Inuvialuit Settlement region during field campaigns in 2022, 2023, and 2024. Each column represents an individual shrub, and each row corresponds to a calendar year. Years of anomaly occurrence result from ring growth width crossdating following established shrub dendrochronological methods. Entries record the presence, type, and relative intensity of intra-annual ring anomalies. The dataset enables comparisons of growth disturbances and climate related stress events constraining shrub growth in Low Arctic tundra. These data were collected as part of the Beavers and Socio-ecological Resilience in Inuit Nunangat (BARIN) project. Funding was provided by the UK Research and Innovation Canada Inuit Nunangat UK Arctic research programme (CINUK) grant NE/X002578/1.
