@dianastuder please see my post here.
We just released an update to the model and we’ve gone back to using the grid approach. The maps are looking overall better to me, eg for Hibbertia dentata this the new map, which covers the coast:
In the previous model this coastal observation was not getting a Hibbertia dentata suggestion but it is now, which is good.
The Crotalus ruber map is also tighter and doesn’t go way far north out of range for the species like the last version did.
But like any model it’s still not perfect and the observation in the OP here is now again just outside the expected nearby range. We’ll keep working on improving it. I suspect a lot of the San Jacinto problems have to do with both the area’s extreme changes in elevation and an unlucky placement of grid cells in the area.
