Columnar Growth in Western Redcedar

12:00 pm - 1:00 pm
Location: The Old Church - 3704 1st Ave Smithers, BC

About the presentation

Adriana will provide an update on her study that seeks to better understand columnar growth of western redcedar (Thuja plicata) in the Kitimat Valley. In her research, Adriana assesses the effects of industrial aerial emissions in gas exchange, foliage, and soil accumulation of contaminants like fluoride. In this presentation, Adriana will compare her previous findings from 2014 (Soderberg smelter) with data collected in 2017 (pre-baked smelter).

Relevance to Northwest BC

Thuja plicata, commonly called western redcedar, has been of great importance for the Northwest Coast First Nations and it is one of the most valuable tree species in British Columbia, considering its ecological, silvical, timber, and cultural values. Western redcedar is a tolerant species to aerial contaminants that shows clear changes in its growth pattern under industrial aerial emissions. Therefore, it might be a useful indicator species in terms of its response to air quality in the Northwest coast forest.
