Morrison Creek Lamprey Survey Data
Morrison Creek lamprey, Lampetra richardsoni variety marifuga are found only in Morrison Creek in Courtenay, BC. In 1995, this variety was designated Endangered by COSEWIC and is currently protected under the Species at Risk Act (SARA). For the years, 2011-2013 and 2015-2017, efforts were made to live trap Morrison Creek lamprey on and around spawning time. In 2014, DFO worked collaboratively with Hancock Forestry Management to assess the extent of the distribution of lamprey within the headwaters of Morrison creek on the land owned by the company. This dataset includes data for 2011 to 2017 inclusive.

Scientific survey of sea scallop (Placopecten magellanicus) and Icelandic scallop (Chlamys islandica) around the Magdalen Islands (fishing area 20A)
Since 1985, research surveys targeting scallops—primarily the sea scallop (Placopecten magellanicus) and, to a lesser extent, the Icelandic scallop (Chlamys islandica)—have been conducted by Fisheries and Oceans Canada (DFO) at one- or two-year intervals around the Magdalen Islands (fishing area 20A). The main objective of this survey is to assess the status of sea scallop stocks. The study area is situated south of the Magdalen Islands, where scallop beds are typically sampled at depths ranging from approximately 25 to 35 m. Sampling stations are randomly selected from a predetermined fixed grid, with sampling conducted along transects at these randomly assigned locations within the study area. Each station is sampled using a lined Digby scallop dredge (20 mm mesh size), towed for roughly 500 m across the seabed.This publication includes three files: the file biometriePetoncle_20, which contains detailed biometric data (species, size, weights and sex) from 1998 to 2024; the file taillePetoncle_20, which provides the size of the individuals sampled from 2009 to 2024; and the file traitPetoncle_20 which contains the abundances and densities per tow from 2009 to 2024. Data on abundances and densities per tow from 1998-2008 is available upon request.This dataset is updated every one to two years as data becomes available. A cleaning of aberrant data has been carried out. However, there is missing data in various columns of the dataset – use the data with caution. If you have any questions please contact DFO.DataManagementSAISB-GestionDonneesDAISS.MPO@dfo-mpo.gc.ca or the author. For certain time periods, associated species are identified and semi-quantitatively counted directly on the sorting table, and the results are presented in the following publications: - https://open.canada.ca/data/en/dataset/6529a4b0-f863-4568-ac71-1fa26cf68679- https://open.canada.ca/data/en/dataset/71732ad5-5c70-4dbf-916d-a94e1380c53b

Historic silviculture activities - 50k
These are the specific silviculture activities that took place within an opening in order to meet silviculture obligations after a disturbance. These activities may have been conducted over the entire opening or just a portion of the opening, and multiple activities may overlap. This database is the most current information available, but will be updated as new information is added.ACTIVITY_CATEGORY - This is the broad category of activity, such as disturbance, site preparation, planting, or survey.ACTIVITY_NAME - This is the specific activity that occurred in the opening.ACTIVITY_AREA - This is the measured within the opening that the activity occurred on.ACTIVITY_STATUS - This is the status of the activity which is either planned, started, or completed.ACTIVITY_COMPLETED_DATE - This is the date that the activity was finished.Distributed from [GeoYukon](https://yukon.ca/geoyukon) by the [Government of Yukon](https://yukon.ca/maps) .
