Hi @gis4sd,
Did you try updating the half saturation constant k? See this post here: Habitat Quality output - interpreting values.
The User’s Guide for the model mentions:
“In general, you want to set k (the half saturation constant) to half of the highest grid cell degradation value on the landscape. To perform this model calibration you will have to the run the model once to find the highest degradation value and set k for your landscape.”
Do you think you could try that and see if the values appear more reasonable?
