If an exhibit has the wrong kind of plant (i. e. desert plant in a boreal habitat) for an animal, make it so it is highlighted or something instead of having to manually searching for it. Planet Zoo has a similar system in place.

A quick way to remove all wrong plants within an enclosure is to select all plants within a biome while using the plant brush and then set it to remove foliage mode and sweep the habitat. That should delete the selected plants only, and ignore all of the other plant types.
A highlight could still be very useful addition
