This dataset consists of digitized surface canopy extent for two species of canopy forming kelp – giant kelp (Macrocystis pyrifera) and bull kelp (Nereocystis luetkeana) – for regions on the Central Coast of British Columbia, Canada. These data were collected as part of the Hakai Institute Habitat Mapping Program which includes long-term observations in canopy kelp extent. Spatial datasets of kelp canopy were derived from high resolution aerial imagery (10 cm) collected from fixed-wing aerial surveys flown in 2020, 2021 and 2022. The survey regions included (1) northwest Calvert Island, (2) Goose Group and McMullin Group, (3) Simonds Group to Triquet Island, and (4) Athlone Island to Stryker Island. 
Survey windows were considered based on obtaining imagery during maximum kelp extent and during a low tide cycle therefore survey windows were planned between July through early September during tides of less than +2.0 m (mean low low water).
Imagery Capture: Four-band imagery (red-green-blue-near infrared) was collected using two high resolution cameras aboard the Aerial Coastal Observatory (a fixed-wing aircraft). Imagery collection and orthomosaic processing is described in associated reports linked in this record.
Kelp delineation: Surface kelp canopy is represented by polygons which were digitized using a blue-near infrared image index. Classification of polygon features was completed manually by a trained analyst. Datasets were reviewed by a secondary analyst for quality analysis/quality control purposes.

The Colombier coastline is one of those rare environments that are still relatively unvisited. It also contains two of the 20 main coastal habitats of interest on the north shore of the St. Lawrence Estuary, namely the Îlets Jérémie, an area of exceptional ecological wealth, and the western shore of the Betsiamites River estuary, a fragile sandy area subject to repeated all-terrain vehicle traffic. During the workshops on coastal habitats held in September 2004, three other sectors
de Colombier were identified as habitats of interest, namely the Baie des Plongeurs at the western limit of the municipality, the Blanche River estuary and Cap Colombier. 

The main objective pursued in carrying out this plan is to propose actions for the conservation and development of the Colombier coastline through an integrated approach that takes into account both the community, environmental and economic aspects of the region while emphasizing the preservation of sensitive ecological sectors.

Ancestral sea gardens supported human settlements for at least 3800 years on the Northwest Coast of North America, Les jardins marins ancestraux ont soutenu les établissements humains pendant au moins 3 800 ans sur la côte nord-ouest de l'Amérique du Nord.

Keywords: dating-methods, gis, niveau-de-leau, archaeology, seasurfaceheight, northwest-coast, oceans, autre, niveau-eau, other, traditional-marine-management, clam-gardens, sea-level
Temporal coverage: 2016-05-29/2022-06-30

The relationships between clam gardens and human settlement throughout the millennia reflects the inseparable links among human demographics, marine management systems, and the social-ecological contexts in which they are embedded.  However, it can be difficult to assign causation between the initiation and development of eco-cultural innovations like clam gardens and the proliferation of human societies due to the temporal uncertainties associated with both.  Here, we bring together data on the shape of the local relative sea level curve, clam garden wall elevation as determined by GIS and drone imagery, radiocarbon dates of clam garden walls, and ecological and archaeological field observations, to assign proxy ages for the clam garden walls of different tidal heights in Kanish and Waiatt Bay on northern Quadra Island.  These data, combined with our mapping and dating of settlement sites, demonstrate a temporal relationship between clam garden building effort and the densification of human settlements.  In Kanish Bay, where we have high resolution data, clam gardens begin to be constructed in significant numbers at least 3800 years ago; this corresponds to a time of increased establishment of large human settlements.  The corresponding increase in settlements and clam gardens reflects both the need to increase sustainable food production and the larger number of people who could sustain the ecological and social foundations of the production system.  The correlation between number and area of clam gardens and the number of new, large settlements continues until ~2000 years ago.  After this time, existing settlements increase in size, but no additional large settlements were established. New clam gardens continue to be built but in seemingly lower numbers. This shift in settlements and clam gardens suggest that a threshold in social-ecological carrying capacity may have been reached in this land and seascape. In the last few centuries, there is a dramatic decline in the number of clam gardens and evidence of human settlement, corresponding to social and ecological changes associated with European colonization.  Taken together, these data demonstrate the strong linkages among Indigenous peoples, their lands and seas, and resilient food systems over the millennia.

Thirteen residents or migratory species of marine mammals generally border the St. Lawrence Estuary. This is why several initiatives have been undertaken to protect marine mammals in the St. Lawrence Estuary. A number of governmental, municipal and community actors have acquired particular expertise there and are currently working in this field. This is why the actions proposed in this intervention plan are mainly focused on aspects that have not been addressed by other organizations and for which the ZIP Committee and its partners have the necessary expertise. Thus, following a preliminary analysis and meetings between the members of the guidance and support committee, two fields of intervention were identified: 

- Marine observation activities between Baie-Comeau and Pointe-des-Monts and boating on the north shore of the St. Lawrence Estuary

- The development of the Maritime Trail on the north shore of the estuary (The Blue Whale Route).

The project “Cleaning illegal garbage dumps located along the coastline in the MRC de la Haute-Côte-Nord” aims to clean the region (from Tadoussac to Colombier) of existing illegal dumps, as well as to raise awareness among the local population (“young people” in particular, but also all people in municipalities as well as in the indigenous community of Essipit) to the problem of illegal dumps in order to avoid: refill them after cleaning. 

The main objectives include organizing a campaign to clean up sites where clandestine waste deposits are found; organizing a campaign to raise awareness among the population adapted for each municipality to environmental damage and the risks of this type of pollution on human health; applying approaches to directing people to official landfill sites; and taking care of cleaned sites.

Temporal coverage: 2016-06-27/2018-11-24

The barnacle dynamics dataset is a component of the Hakai Institute’s Nearshore research and monitoring program, designed to capture change in rocky intertidal habitats. The overarching objective of Hakai Nearshore research is to investigate the role of habitats and their associated communities, in the face of stress and disturbances from global climate change and local coastal perturbations. 

The barnacle community was assessed from 2016-2018 at three coastal sites along the northwest edge of Calvert Island on the Central Coast of British Columbia. All three sites were exposed rocky shorelines with contiguous zones of substrate dominated by species of barnacle. The abundance and diversity of the barnacle species within these zones was surveyed using point-intercepts within permanent plots. The sites were surveyed on an approximately monthly basis from May-September, and two winter surveys in November and February.  Six surveys were conducted in 2018, 5 in 2017, and 3 in 2016.
