I know a lot of people know this, but in case you don't.....
First, you need grid squares on your map. To do this, press ctrl+G. Doing it again will result in the grids being taken off the map. Get it? Got it? Good.
Okay, so now for the actual tree trick. There are a lot of trees where you can fit four of them in a single grid. The thing is, the game calculates each grid (instead of each tree) as 1% of the exhibit's foliage. For example, let's say an animal likes 5% of foliage, and its preferred tree is the mangrove tree. To make the exhibit more suitable for the animal, you could put four mangrove trees in each of the five grid squares (total of twenty trees). And yes, for most animals that like trees that take up grid quadrants, putting four trees to each grid does increase suitability...
Now, how to use this information. If the animal likes a tree that can have four trees to a grid, put a single tree in each grid until one of the animals gives a sad face. Then, delete the tree that caused the sad face. Fill all the squares with a tree in them so there are four trees to each grid. You'll notice that each time you put another tree in a grid where there was already a tree, the animal gives a happy face even though it complained about the earlier tree that was the first to be put into a grid.
Note on rocks: This does not apply to rocks. Rocks are counted induvidually, not by grids.
