A database of verified tornado occurrences across Canada has been created covering the 30-year period from 1980 to 2009. The data are stored in a Microsoft Excel spreadsheet, including fields for date, time, location, Fujita Rating (intensity), path information, fatalities, injuries, and damage...

This polygon outlines the basic area included in the survey counts. This area is the best approximation of the mudflat that can be surveyed from shore and is exposed at tide tide height of 3.5 m, based on tidal predictions at Point Atkinson, British Columbia.

This line outlines the basic survey route included in the survey counts. This route is the best access to areas that can be surveyed from shore.

Hotspots represent active wildfires. Natural Resources Canada Canadian Wild Fire Information System identifies them by processing Infrared satellite images. This layer contains the hotspots that are selected to be used as input for the Regional Air Quality Deterministic Prediction System FireWork...

Grids surveyed is a polygon feature class containing the 5’ latitude by 5’ longitude grid cells surveyed for all seasons combined including the grids that were surveyed but where no species were seen. In order to produce maps for a specific season a selection for these grids must be performed.

Average grid cell density is a polygon feature class containing the average density value for each grid cell per species/groups and season.
