The "Prairie Agricultural Landscapes (PAL)" datasets identify areas of the agricultural portions of the Canadian Prairies with similar land and water resources, land use and farming practices. They are represented by vector polygons. Based on selected attributes from the Soil Landscapes of Canada (SLC) and the 1996 Census of Agriculture, the Prairies were classified into 13 (thirteen) classes of Land Practices Group and five (5) Major Land Practices Groups. Typical attributes used to define the Land Practice Groups include: land in pasture, land in summerfallow, crop mixture, farm size and the level of chemical and fertilizer inputs. The five (5) Major Groups were devised to help better understand the relationships between the groups.

Forests cover large areas of Canada but only some of these forests are actively managed. The Map of Forest Management in Canada provides a generalized classification of forest management in Canada, including: protected areas, Treaty/Settlement Lands (including Treaty Lands identified in Final Agreements, Land Claim Agreements and Settlements), Indian Reserves, other federal reserves (including military training areas), provincial and territorial reserves and restricted use areas, private lands, short- and long-term Crown forest tenure areas and areas with no current Crown timber dispositions. The Managed Forest Map of Canada dataset provides a wall-to-wall classification of lands in Canada. It does not differentiate areas of forest from non-forest. The Managed Forest Map of Canada differs from maps defining the area designated as “managed forest” for greenhouse gas inventory reporting purposes and does not replace those maps. Instead, the Managed Forest Map of Canada shows areas that are currently managed, as of June 2017, and provides generalized management type classification for those areas. Collaborating agencies plan to update the dataset periodically as needed, and remain open to receiving advice from experts concerning refinement priorities for future versions.

This publication contains thirteen (13) maps of different biogeochemical and soil properties of forest ecosystems of Canada’s managed forest.

Catch, effort, location (latitude, longitude), and associated biological data from groundfish multi-species longline surveys in British Columbia. Introduction This is a set of long-term and coordinated surveys that together cover most of the nearshore, hard-bottom habitat of coastal British Columbia. The objective of these surveys is to provide fishery-independent abundance indices and associated biological data for the assessment of nearshore rockfishes and other groundfish species that live on untrawlable, hard bottom habitats. The surveys use standardized “snap and swivel” longline hook gear set on the ocean floor. The surveys follow a random depth-stratified design and the sampling units are 2 km by 2 km blocks. The Inside Hard Bottom Longline (HBLL) Surveys are conducted by Fisheries and Oceans Canada (DFO) and take place on the Canadian Coast Guard Research Vessel Neocaligus. The Inside surveys cover the inlets and protected waters east of Vancouver Island (Pacific Fishery Management areas 12 – 20 and 27- 29). The survey area is divided into a northern and southern region, which are surveyed in alternating years. The Inside North region includes Johnstone Strait and Broughton Archipelago. The Inside South region includes Desolation Sound, the Strait of Georgia and southern Gulf Islands. The Inside HBLL surveys use size 13/0 circle hooks, baited with frozen squid. The Outside HBLL Surveys are conducted by DFO in collaboration with the Pacific Halibut Management Association (PHMA) and take place on several chartered commercial fishing vessels each year. The Outside surveys cover most of the British Columbia coastline, excluding the inlets and protected waters east of Vancouver Island (i.e. excluding Pacific Fishery Management areas 12 – 20 and 27- 29). The survey area is divided into a northern and southern region, which are surveyed in alternating years. The Outside North region includes the mainland coast north of Milbanke Sound, Dixon Entrance, and the east and west coasts of Haida Gwaii. The Outside South region includes the mainland coast south of Milbanke Sound, Queen Charlotte Sound, and the north and west coasts of Vancouver Island. The PHMA provides the chartered commercial fishing vessels and field technicians, while DFO provides support for running the surveys, including survey design and equipment. The Outside HBLL surveys use size 14/0 circle hooks, baited with frozen squid.

Catch, effort, location (latitude and longitude), and associated biological data from the Hecate Strait Multispecies Assemblage Bottom Trawl Surveys in Hecate Strait, British Columbia. Introduction The Hecate Strait Multispecies Assemblage Bottom Trawl survey series consists of twelve surveys that were conducted from 1984 to 2003 by the Pacific Biological Station, Fisheries and Oceans Canada. The main objective of this survey series was to collect detailed catch and biological data on species assemblages in order to develop an ecological basis for mixed species stock assessment in Hecate Strait. These surveys also provided abundance indices for individual species and were a source of information on recruitment. The surveys were conducted using a combination of charter vessels and two Canadian Coast Guard Research Vessels, the R/V G.B. Reed and R/V W.E. Ricker. To determine haul locations, a grid of 19 km² (10 nautical miles²) blocks were used with an attempt made to establish one trawl site within each 18 metre depth interval within each block. The 1984 survey involved one chartered and one research vessel; all other surveys were single vessel surveys. The Hecate Strait Multispecies Assemblage Bottom Trawl survey series surveyed Pacific Fishery Management areas 4, 5, and 101 to 106. A total of 1,111 number of tows were made with a Yankee 36 trawl net. This survey series is the predecessor for the present day Hecate Strait Synoptic Bottom Trawl Survey and represents one of the longest running time series of fisheries independent groundfish surveys on the west coast. For further details about the Hecate Strait Multispecies assemblage bottom trawl survey series, a list of reports can be found in the supporting documents section. Effort This table contains information about the survey trips and fishing events (trawl tows/sets) that are part of this survey series. Trip-level information includes the year the survey took place, a unique trip identifier, the vessel that conducted the survey, and the trip start and end dates (the dates the vessel was away from the dock conducting the survey). Set-level information includes the date, time, location, and depth that fishing took place, as well as information that can be used to calculate fishing effort (duration) and swept area. All successful fishing events are included, regardless of what was caught. Catch This table contains the catch information from successful fishing events. Catches are identified to species or to the lowest taxonomic level possible. Most catches are weighed, but some are too small (“trace” amounts) or too large (e.g. very large Big Skate). The unique trip identifier and set number are included so that catches can be related to the fishing event information (including capture location). Biology This table contains the available biological data for catches which were sampled. Data may include any or all of length, sex, weight, age. Different length types are measured depending on the species. Age structures are collected when possible for species where validated aging methods exist and are archived until required for an assessment; therefore, all existing structures have not been aged at this time. The unique trip identifier and set number are included so that samples can be related to the fishing event and catch information. Biomass This table contains relative biomass indices of species that have been captured in every survey of the time series. The coefficient of variation and bootstrapped 95% confidence intervals are provided for each index. The groundfish data synopsis report (Anderson et al. 2019) provides an explanation of how the relative biomass indices are derived.

Catch, effort, location (latitude and longitude), and associated biological data from groundfish multi-species longline surveys in the northern portion of the inlets and protected waters east of Vancouver Island, British Columbia. Introduction The Inside North Hard Bottom Longline (HBLL) survey is one of a set of long-term and coordinated surveys that together cover most of the nearshore, hard-bottom habitat of coastal British Columbia. The other surveys are the Inside South HBLL survey, Outside North HBLL survey, and Outside South HBLL survey. The Inside North HBLL survey was first conducted in 2003, and repeated in 2004 and 2007. Starting in 2008, this survey has been repeated every second year, in alternate years to the Inside South HBLL survey, with the exception that no surveys were conducted in 2017. The survey was not impacted by the COVID-19 pandemic. The objective of these surveys is to provide fishery-independent abundance indices and associated biological data for the assessment of nearshore rockfishes and other groundfish species that live on untrawlable, hard bottom habitats. The surveys follow a random depth-stratified design and the sampling units are 2 km by 2 km blocks. The surveys use size 13/0 circle hooks, baited with frozen squid. The Inside North HBLL Survey is conducted by Fisheries and Oceans Canada (DFO) and takes place on the Canadian Coast Guard Research Vessel Neocaligus. This survey covers the northern portion of the inlets and protected waters east of Vancouver Island, including Johnstone Strait and Broughton Archipelago in Pacific Fishery Management areas (PFMAs) 12 and 13. Effort This table contains information about the survey trips and fishing events (sets) that are part of this survey series. Trip-level information includes the year the survey took place, a unique trip identifier, the vessel that conducted the survey and the trip start and end dates (the dates the vessel was away from the dock conducting the survey). Set-level information includes the date, time, location and depth that fishing took place, soak time, hook spacing, and numbers of hooks counted. All successful fishing events are included, regardless of what was caught. Catch This table contains the catch information from successful fishing events. Catches are identified to species or to the lowest taxonomic level possible. From 2003 to 2016, all catches are counted, and most catches are weighed; some catches are too small (“trace” amounts) or too large (e.g. very large Big Skate) to weigh. From 2019 onwards, catches are recorded as counts only. The unique trip identifier and set number are included so that catches can be related to the fishing event information (including capture location). Biology This table contains the available biological data for catches which were sampled. Data may include any or all of length, sex, weight, age. Different length types are measured depending on the species. Age structures are collected when possible for species where validated aging methods exist and are archived until required for an assessment; therefore, all existing structures have not been aged at this time. Tissue samples (usually a fin clip) may be collected for genetic (DNA) analysis for some individuals of particular species. Genetic samples may be archived until required for analysis; for more information please see the data contacts. The unique trip identifier and set number are included so that samples can be related to the fishing event and catch information.
