## Information document concerning the results of the threat analysis

This document provides additional information to better understand and use the threat data produced as part of the integrated recovery approach. This data highlights the sectors where the impacts of threats on occurrences listed by the [Quebec Natural Heritage Data Center (CDPNQ)] (https://www.quebec.ca/gouvernement/gouvernement-ouvert/transparence-performance/indicateurs-statistiques/donnees-especes-situation-precaire) are the most important.

Threats: Threats are activities that, by their location, intensity, or time in which they occur, generate stress (see next section) that affects elements of biodiversity. In total, the available data concerns 16 threats:

* Future conversion risk: Development of residential, industrial and commercial areas;

* Ski resorts;

* Future conversion risk: Annual agriculture (field crops);

* Sustainable agriculture;

* Quarries and sandpits;

* Roads;

* Total removal of forest cover;

* Partial removal of forest cover;

* Educational treatments;

* Motorized vehicles;

* Boating;

* Drainage in agricultural areas;

* Phragmites australis;

* Rhamnus cathartica;

* Increase in predation by mesopredators;

* Nutrient load.

# #Méthode for calculating the impact rating

* The method used to calculate the impact score is presented in the document Integrated Recovery Approach for Threatened or Vulnerable Species — Development of a New Tool for Conservation Planning.

* The results are presented using a map grid in which each 10 km x 10 km plot shows the cumulative impact of a threat on the occurrences present in this portion of territory. The cumulative impact is obtained by adding up the impact ratings of all the occurrences present within the plot. This accumulation makes it possible to identify, using a color code, the “hot spots” of a threat on occurrences. The absence of color indicates the absence of calculated or listed impacts on occurrences. The color gradient illustrates the variation in the cumulative impact of this threat on all occurrences in the plot, from the lowest score (yellow) to the highest (red).

* Each threat is presented on a separate layer, while an additional layer called “Threat Compilation” shows the sum of the threats over all the occurrences present in a plot.

# #Quelle is standardized classification used for analysis?

The threats analyzed were defined according to the document Standardized Classification of Threats Affecting Biodiversity — Definitions for the Quebec Conservation Data Center (CDC) v1.0, published in 2021.**This third party metadata element was translated using an automated translation tool (Amazon Translate).**
