I have already mentioned the various plants that can be enjoyed at the Fullerton Arboretum. There are other things that can be observed and studied by students and other people as well. There are different animals and insects that make the arboretum their home or just come to visit. On my visit here I observed ducks swimming in the water and sunning themselves on the grass. I took a picture of a squirrel that was digging a hole in the ground. There were also squirrels climbing and jumping from tree to tree. This was interesting to watch because the squirrels can jump fairly large distances. More than once as I was walking around the plants and trees I found myself walking into large spider webs. There are also different types of birds and butterflies flying in the arboretum. By taking students on a fieldtrip to this location they can observe these animals and maybe more!
