Cultural land-use plays a significant role in ecosystem change, especially in shaping the composition of species in a region over time. Recent research in northwestern North America focuses on how historical Indigenous land-use and forest management have created relict forest gardens dominated by edible trees and shrubs. This research combines archaeological and ecological methods to better understand the historical ecology of these forest gardens, and identifies indicator species that are culturally significant. The study also reveals evidence of pre-colonial forest management practices and emphasizes the importance of revitalizing and supporting Indigenous peoples' role in sustaining these cultural landscapes.
Cultural land-use is an important driver of ecosystem change, influencing the composition of species across landscapes and through time. Recent research in northwestern North America has shown that historical Indigenous land-use and forest management has resulted in relict forest gardens dominated by edible fruit, nut, and berry producing trees and shrubs - many of which continue to grow adjacent to archaeological village sites today. Our research combines archaeological and ecological methods to better understand the historical ecology of seven forest gardens in the Pacific Northwest. Vascular plant communities at all sites are evaluated for distinctiveness using ANOSIM, NMDS, and indicator species analyses. We identify 15 forest garden indicator species, all of which are culturally significant edible fruit or root-bearing species. We then present the results of an intensive historical-ecological study of one site in Laxyuubm Gitselasu (Ts'msyen). Paleoethnobotanical data, soil and tree ring analyses, and radiocarbon dates show that forest management in the Gitsaex forest garden of Gitselasu pre-dates settler colonialism and shows that people likely modified soils and otherwise enhanced their immediate environment to increase the productivity of desired plant species. Given the importance of Indigenous peoples' role in sustaining forested foodsheds, there is an ongoing and urgent need to support their revitalization and management and better understand the integrated cultural practices and ecological processes that result in these vast cultural landscapes.
