The Hakai Institute Marine Habitat Mapping Program is focused on documenting the spatial changes and drivers in coastal marine ecosystems (kelp and eelgrass) at various spatial scales in British Columbia (local, regional and coast-wide). To study regional scale trends we are developing and refining methods for mapping species-specific kelp extent and biomass using high-resolution aerial imagery to inform the long-term collection of kelp distribution in British Columbia.    

Canopy-forming kelps are a critical component of many nearshore marine ecosystems, including those of British Columbia. The canopy kelps Nereocystis luetkeana (bull kelp) and Macrocystis pyrifera (giant kelp) form complex, three-dimensional habitat that supports a diversity of fish, invertebrates and marine mammals. Canopy kelps are also amongst the most productive primary producers on the planet, serving as an important source of carbon to coastal food webs. 

Like many other kelp species, canopy-forming kelps show high seasonal and interannual variability as their recruitment, growth and survival are influenced by a number of abiotic (e.g. temperature, salinity, nutrients, light) and biotic (e.g. grazing, intraspecific competition) drivers. As a result, kelp populations are expected to change in response to shifts in underlying environmental conditions associated with climate change. They may also shift in response to changes in the biotic community (e.g. sea otter recovery, sea star wasting disease) or human activities (e.g. sea urchin harvest, kelp harvest). 

Surveys conducted by the Hakai ACO are targeted to collect imagery during summer low tides when kelp biomass is at its highest. Low tide imagery is also necessary for mapping other nearshore habitats such as eelgrass. The high resolution of the aerial cameras permit the discrimination of different kelp species.

The Seagrass Site-Level Production dataset is a component of Hakai Institute’s Nearshore research and monitoring program, designed to determine the drivers of change in seagrass ecosystems. 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.

This data package contains seagrass (Zostera marina) primary production observations collected from May 2015 to Feb 2019, at long-term seagrass meadow monitoring sites on British Columbia’s Central Coast. SCUBA divers collected data from 9 sites annually and 1-3 sites seasonally along permanent 30m transects. Primary productivity data was collected during two concurrent, but separate surveys (i.e., different parameters, methodologies, and sample designs). The data files included in this data package are: 1) ‘Habitat’ surveys, focused on landscape-level habitat variables (e.g., substrate type, subdominant vegetation, adjacent habitat types, seagrass patchiness), and 2) ‘Density’ surveys measuring seagrass specific variables at a finer scale (e.g., seagrass shoot density, and canopy height). Data included here are a subset of the Hakai Institute’s seagrass monitoring dataset.

This data package is freely available to everyone, following the principles of equitable access and benefit sharing. However, we expect all data users to give attribution to the data providers (read our data license) and the use of these data should happen in the light of fair use, i.e.: 1) respect the data providers, and provide helpful feedback on data quality, and 2) communicate and/or collaborate with the providers if you are considering using this dataset for manuscripts or other forms of reporting.

The team of the Comité ZIP Sud-de-l'Estuaire, in collaboration with the municipality of Notre-Dame-des-Neiges, carried out a characterization of the hydro-sedimentary unit of the area des Grèves. The main objective is to determine a potential site for restoring fish habitat as part of a project funded by Fisheries and Oceans Canada. Biological and geomorphological characterization was carried out in the summer of 2018.

The characterization of the territory made it possible to obtain a global and current portrait of the study area. The areas of ​​the saltwater marsh and the eelgrass bed have been mapped. Despite degradation in specific sectors, these seem to be in good health. Inventories of flora and fauna have given an idea of ​​the species present in this sector. To limit the phenomenon of erosion and improve the resilience of the environment, a transplant project in the marsh, a sedimentary recharge, and a planting of native species adapted to the conditions are planned for the summer of 2019.

This is a polygon layer mapping kelp canopy extent for the McNaughton Group islands, Manley Island, and Serpent Group Islands.

Kelp canopy extent was mapped from imagery taken using an unoccupied aerial system (UAS). McNaughton Imagery was taken in late May 2017, the Manley images were captured in late July 2017, and the Serpent Group images were made in early July 2016. The images were captured using a DJI Phantom 3 professional UAS equipped with a commercial grade 4k RGB (See attached UAS methods). Kelp bed polygons were drawn manually in ArcGIS 10.5.1. Only beds containing greater than ~3 fronds were mapped. Beds were considered connected when less than ~5m separated them. Single fronds and single frond outliers were not digitized. Vertices were placed every 4m or less (more vertices were used on complex shapes). The attributes in this table are limited to the perimeter length (m) and area (m^2) of each kelp bed polygon. Area was determined in the NAD_1983_CSRS_BC_Environment_Albers projection. Species and bed density were not recorded for this dataset.

The impacts of fisheries activities in the St. Lawrence are evaluated using DFO fisheries logbooks program. While logbooks are not mandatory for all fisheries in the St. Lawrence, they still provide a very thorough overview of the spatial distribution and intensity of fishing activities in the St. Lawrence. The data we used spans 6 years from 2010 to 2015 and details 218323 fishing events (approximately 36387 fishing events per year). There were 31 targeted species and a total of 53 caught species in the dataset.

Fishing activities are performed using a variety of gear types: trap, trawl, dredge, driftnet, hand line, longline, scuba diving, purse seine, seine, beach seine and jig fishing. Intensity of fishing activities was divided among gear types and based on their respective types of environmental impacts. For example, traps and trawls have very different effects on a system. Gear classification was done using the classification presented in [Halpern et al. (2008)](https://www.science.org/doi/10.1126/science.1149345) and [Halpern et al. (2015a)](https://knb.ecoinformatics.org/view/doi:10.5063/F1S180FS) and is broken down into 5 distinct classes: demersal destructive (DD), demersal non-destructive low-bycatch (DNL), demersal non-destructive high-bycatch (DNH), pelagic low-bycatch (PLB) and pelagic high-bycatch (PHB). This categorization therefore divides the fisheries data into 5 distinct driver layers characterizing fishing activities. Gear types can also be further classified into fixed or mobile engines based on their mobility. We used these two mobility classes to generate a buffer of impact around each fishing activity coordinates to consider potential spatial uncertainty associated with locations and the fact that mobile engines can be tracted over several kilometers during fishing activities and that we do not have the beginning and end points of mobile fishing events. Buffer sizes for fixed and mobile engine was of 200 and 2000 meters, respectively. To characterize the intensity of fishing activities we used a biomass yield density index. We multiplied the total annual biomass captured in each grid cell, regardless of species, by the proportion of fishing area in each grid cell.
