11 000 years of fire history and climate in the mountain hemlock rain forests of southwestern British Columbia based on sedimentary charcoal
High-resolution analysis of macroscopic charcoal from lake sediment cores, along with 102 accelerator mass spectrometry ages on soil charcoal, was used to reconstruct the long-term fire history around two subalpine lakes in the southern Coast and North Cascade Mountains, suggesting that fire regimes are linked to climate via large-scale atmospheric circulation patterns.
Ancient Clam Gardens Increased Shellfish Production: Adaptive Strategies from the Past Can Inform Food Security Today
How ancient shellfish aquaculture practices may have supported food security strategies in the past is revealed and insight into tools for the conservation, management, and governance of intertidal seascapes today is provided.
Ancient Shellfish Mariculture on the Northwest Coast of North America
While there is increasing recognition among archaeologists of the extent to which non-agricultural societies have managed their terrestrial ecosystems, the traditional management of marine ecosystems…

Indigenous marine resource management on the Northwest Coast of North America
There is increasing recognition among anthropologists that indigenous peoples of the Northwest Coast actively managed their terrestrial and marine resources and ecosystems. Such management practices…
Documenting ancient plant management in the northwest of North America 1
This review demonstrates that while finding evidence of ancient plant management can be difficult, such evidence can be found when innovative re- search methods are applied and reconstructions of past plant-management strategies are strengthened considerably.

The long-term fire regime in two forests on the south coast of British Columbia is described by means of 244 AMS radiocarbon dates of charcoal buried in forest soils to support a model of forest dynamics where fires are of minor ecological importance.
“Everything revolves around the herring”: the Heiltsuk–herring relationship through time
Pacific herring (Clupea pallasii) is foundational to many social-ecological systems of the North American coast. The indigenous people of Heiltsuk First Nation on the central coast of British…
