I want to solve the problem of habitat quality degradation that has always been zero
Welcome to the forum @glance -
It would be helpful to know more information about your model run and results. Does the quality_c.tif output also have values that are all 0? Does the map for deg_sum_c_1980,tif show any visible difference in values, even though the legend says that it’s all 0?
And please upload the log file that is created in your Workspace. The filename is long and ends in “.txt”, and has additional information that might help us troubleshoot. Thank you.
