Habitat Quality: Accessibility to Threats

I was wondering if you could please clarify whether the accessibility layer refers to the current land cover or the future one in the model. For example, I am working on a case study where the zoning access has been changed between, say, 2000 and 2007. If my current land cover is for year 2000, should I use an accessibility layer for year 2000 or one for 2007? Does the model account for a changed zoning?

    Hi Francesco,  The Habitat Quality model assumes that the accessibility layer does not change between the current and future scenarios.

    To run the model with different accessibility for each scenario, you could run the model with the land cover from year 2000 as the current scenario, and then again with the land cover and accessibility vector from year 2007 as the current scenario.
