Abstract
Indigenous peoples’ legacies of plant cultivation and management can have profound effects on contemporary forest structure and species composition long after cultivation has ceased. Despite rich ethnographic accounts of practices like orcharding and fruit tree management in the Pacific Northwest, archaeological and ecological research documenting these practises have been lacking. To investigate ancient and historical land-use and cultivation in Nuchatlaht (Nuu-chah-nulth) territory, we undertook a multidisciplinary study combining archaeological surveys on Nootka Island and ecological analyses of seven anomalous plant communities found adjacent to former village sites. Fifty-seven archaeological sites were inventoried, and 16 previously recorded sites were updated, including six notable village sites. Intensive botanical surveys were subject to indicator species analysis, NMDS, and ANOSIM analysis, which suggest that three putative orchard sites were highly enriched for culturally important and edible fruit and root plants, such as Pacific crabapple (Malus fusca), saskatoon berry (Amelanchier alnifolia), salmonberry (Rubus spectabilis), and wild rice root (Fritillaria camschatcensis), and are highly distinctive compared to nearby sites and regional floristic patterns. Four shell midden sites were characterized by plant communities distinct from both orchard sites and control sites. Our archaeological and ecological analyses, alongside ethnohistorical data, strongly suggest a pattern of ancient and/or historical cultural landscape modification by Nuchatlaht peoples to produce food-bearing plant communities in their territories. This compliments findings in other literature, and what Indigenous peoples have long told researchers, that plant resources were routinely encouraged and harvested across their inhabited landscapes.
