Great to hear Mélanie,
- If agriculture is a threat, is it correct to get agricultural data to extract data from the current land use raster and to make a new raster “agriculture”, that will be used as a threat raster?
That sounds like the right process to me.
- It is not clear to me how we must interpret the outputs maps depending on the scenario chosen:
Current and future land use scenarios will allow comparison between current and future habitat quality and degradation. Adding in Baseline LULC will compute Habitat Rarity maps for current and future scenarios. Documentation for Habitat Rarity.
- What is accoridngto you the most interesting scenario?
I won’t be much help with this question, I’m just a software engineer! This will really depend on your study area and the research questions you’re trying to answer. If by chance you are referring to question number 2, then I think just comparing a current and future landscape and threats is a great place to start.
- If I use baseline and/or future land use maps, I should have set of threat rasters associated to each time (one group for baseline, one for current, oen for future). However, I was able to run baseline + current model with only threat maps for current (but not for baseline) and it works. If I dont include these set of threat rasters, what is the consequence on the outputs? Is it stil relevant to run the models witrh a baseline and/or future maps?
Baseline does NOT require associated threat rasters. If no threat rasters are found for Baseline then only Rarity outputs will be generated. If threat rasters are found for Baseline, then Habitat Quality and Degradation are also computed for the Baseline LULC. A future scenario LULC and associated threat rasters will allow you to compare against a current scenario. If Baseline is included then Rarity will be computed for current and future scenarios.
- If I use baselin/andor future land use maps, how to get the data for the threat rasters? Is the method I mentioned in point 1 would be appropriate (reclassify baseline map in differnet threat rasters for agricture, mining, etc for instance?)
I think that makes sense. If you have a baseline and future LULC maps then generating the threat rasters from them seems reasonable. Please refer to the Data Needs section of the Users’ Guide for information on Baseline LULC codes.
