Issues concerning habitat conservation and protection are strikingly varied, such as climate change, habitat integrity, habitat biodiversity, and habitat sustainability. Risk assessments typically start with an issue related to a condition (i.e. remaining types of natural habitats, extent of protected areas), and then determining the stressor factors (i.e. what land use caused the condition? how fast and where is land use conversion happening?) that are associated with the conditions. Finally, responses (i.e. actions that have been taken or could be taken) to improve conditions or mitigate the stressors are assessed. Various types of perspectives and scenarios can, and should, be analysed using the model of conditions, stressors and responses.

Habitat risk assessments are dependent on the key concerns, available information, and perspectives that people (i.e. decision makers, analysts) have. Any of these factors can shape the outcome. Therefore, the process of developing models of habitats at risk should be considered a way to learn, share views, and examine options with a view to sustaining key habitat areas.

Wildlife Habitat Canada has commonly used provincial, national, and international ecosystem classifications/maps/descriptions as a means to assess the risks and opportunities associated with wildlife habitats. This encourages a more integrated and ecosystem based approach to habitat assessment. The following links will take you to more detailed information about:
