Birds adapted to alpine ecosystems are often sensitive to habitat and climate changes because of their niche specialization. For example, birds that are specialized to breeding in colder alpine conditions may be outcompeted by more generalist species if warmer conditions arise. Yearly data are collected at these sites using audio recorders to determine indices of bird diversity and occupancy trends to inform management.

Prior to 2021, the Government of Canada used Goods and Services Identification Number (GSIN) codes to identify generic product descriptions for its procurement activities. GSIN codes were used to connect all of the procurement information, including Tender Notices, Award Notices, Standing Offers and Supply Arrangements, and Contract History.

The GSIN CSV file published on this page is updated on an “as needed” frequency, when codes are either created or deactivated.

Please see the Mapping of Goods and Services Identification Number to United Nations Standard Products and Services Code dataset for a resource that compares GSIN codes to a subset of …

The international classification system for procurement items called the United Nations Standard Products and Services Code (UNSPSC) began to replace the Government of Canada’s Goods and Services Identification Numbers (GSIN) codes in 2021.

This page contains an open data file that maps the UNSPSC goods and services codes to the Government of Canada’s current system for classifying the Goods and Services: Identification Number (GSIN) at the highest level. The data is available in Comma Separated Values (CSV) file format and can be downloaded to sort, filter, and search information.

Please see the Finding and using UNSPSC Codes page or the …

Yoho National Park assesses the populations of American Pika using surveys of active pika hay piles at various sites throughout the park.

Yoho National Park samples 28 randomly selected potential amphibian breeding sites (out of possible 66) to determine presence or absence of amphibian species. Each of the 28 sites is visited 3 times every 2 years and all detected species are recorded.
