Haida Gwaii
All species are below average, with chum, coho, and pink salmon showing the most dramatic declines
The outlook for salmon on Haida Gwaii is bleak. All species for which we had reliable data are currently below the long-term average, with short-term and long-term trends either stable or declining. The current state for Chinook and steelhead are unknown due to a lack of recent data for both species.
Unlike other regions where pink salmon have been doing relatively well, pink salmon are well-below the long-term average in Haida Gwaii and have a negative long-term trend. Pink salmon are currently doing worse than any other species in Haida Gwaii. However, pink salmon abundance tends to fluctuate widely and Haida Gwaii pink salmon had above-average spawner abundance as recently as 2020.
Chum salmon are of significant conservation concern. They are well-below the long-term average and have a negative long-term trend. Declines in spawner survey effort of chum salmon in Haida Gwaii since the 1980s means that this assessment may not even be capturing the full picture of chum salmon declines, including the loss of critical genetic diversity.
State of Salmon - Haida Gwaii
OUR APPROACH
There are different ways to measure the state of salmon, and each approach tells us something unique about how salmon are doing.
CURRENT STATE is the spawner or total abundance over the most recent generation as a per cent anomaly from the long-term average and provides information on how abundant salmon are now relative to past years.
TRENDS measure the direction of change, either over the short-term (most recent three generations) or long-term (all available years). This is complementary information to the current state, and a species that has a declining trend may be a conservation concern even if the current status is above average.

Arrows indicate if the trend in abundance is increasing or decreasing
A horizontal line indicates if the trend in abundance is stable
A question mark indicates an unknown current state or trend due to a lack of readily accessible data

Well-above long-term average. No conservation concern.
Above long-term average. Current outlook is good.
At or near long-term average. Precaution is warranted.

Unknown current state due to a lack of readily accessible data.
REGION PROFILE
Haida Gwaii
Conservation Units are irreplaceable groups of salmon that have unique genetic and life-history traits. Maintaining multiple Conservation Units within a region strengthens the resilience of the species as a whole and helps it withstand and adapt to changing conditions. The number of Conservation Units provides a good indication of the salmon biodiversity in the region.

Major Salmon-Bearing Rivers
Haida Gwaii is an isolated archipelago of more than 200 islands covering 10,180 square kilometres. Hecate Strait separates Haida Gwaii from mainland British Columbia by about 100 kilometres. Salmon-bearing watersheds on Haida Gwaii range from small streams scattered along the coastline to larger well-known salmon rivers such as the Yakoun and Tlell Rivers. Often called the “Galapagos of the North”, it is home to ecologically diverse temperate rainforest and freshwater wetlands which supports a diversity of spawning and rearing habitats for all species of Pacific salmon and steelhead.
Decades of industrial logging have profoundly impacted the structure and function of salmon ecosystems across Haida Gwaii. Although the legacy of logging will take decades to repair, steps have been made to protect and restore Haida Gwaii’s ecosystems[21]. In 1993, the Gwaii Haanas National Park Reserve and Haida Heritage Site was established to protect 1,500 square kilometres of the archipelago and, since 2012, logging rates have been significantly reduced under co-management by the Haida Nation and the provincial government.
Recreational and commercial fisheries in the region typically intercept salmon on their migrations to other spawning areas. Although the numbers of salmon that actually spawn on Haida Gwaii are relatively small, salmon are a mainstay of cultures and communities in this remote island region. Most streams have a strong return of pink salmon during even calendar years only. Sockeye populations are smaller and are mainly harvested in First Nations food, social, and ceremonial fisheries.
