Rapid climate change is predicted for British Columbia’s Inland Temperate Rainforest (ITR), a globally unique ecosystem. Lichens, which may serve as effective biomonitors of ecosystem health, have been proposed for use as climate change indicators for a variety of ecosystems globally. This research presents a climate biomonitoring protocol using arboreal macrolichen communities in the inland rainforest in British Columbia. We report our initial findings of 39 lichen taxa, including a number of rare species and cyanolichens, which may be especially sensitive to climate. Comparisons of these data with future measurements will provide an indication of how the inland rainforest may be responding to climate change.
