Hi @elin -
That does seem like a pretty small area to model, but I’d say it should be ok, if you have very fine-resolution information on the land cover and threats. What is the resolution of your input layers?
As for threats in particular, we do recommend making sure that your threat layer covers as large of an area as is necessary to include everything that might impact the area of interest. In such a small area, are you able to include all of the towns, agriculture, roads, or whatever else is a threat? As an example, if one of your threats is towns, and towns have an impact radius of 5km, you should be including towns that are up to 5km outside of your area of interest. Similar with roads etc.
