Provides public access to station metadata of hydrometric monitoring locations active and discontinued ; 2. Provides public access to the hydrometric station index listed in stream order beginning with the most upstream stations and extending to the most downstream stations.

This dataset contains blended (gauge and satellite estimates) pentad mean precipitation rates (unit: mm/day) at a one degree spatial resolution over Canada. The data can be used for hydrometeorological, agricultural, forestry modelling, for numerical weather model and climate model verification,...

The North American Breeding Bird Survey (BBS) is a road-based, long-term, continental survey that focuses on measuring breeding bird abundance at 50 stops along roughly 40-km long transects. This collection houses PDFs of active BBS route maps, which are grouped by province or territory. These...

The 2012 Canadian Nature Survey is part of a series of national surveys on the importance of nature to Canadians. The purpose of the survey is to provide reliable, current information about Canadians’ awareness of nature related concepts, their decisions related to nature, and their involvement...
