Question about HRA results...
Nice to meet you. I am excited to have started to use InVEST.
It is quite an impressive piece of tool!
I was willing to verify the calculation process and especially the spatially explicit risk score in shapefile, but I finally got a wrong result.
Here is the setting:
- One habitat (seagrass)
- One stressor (fishing)
In preprocessor, here are the criteria that I have selected:
- Exposure: Intensity Rating
- Sensitivity: Change in Structure Rating
- Resilience: Recovery Time (★ this criteria was modified by spatially explicit risk score in shapefile)
As you can see in the attachment, the Recovery Potential (final ourput) has changed accordingly to the shapefile. It should mean that each patch of the habitat has a different resilience.
But, when applying a stressor of constant intensity, the results in terms of risk are exactly the same. The habitat patch with low resilience should get a higher risk value I suppose. Or am I wrong?
I would appreciate if you could clarify this issue please.
