Manoa Stream Manoa stream has a wide diversity of wildlife. The area has lots of bushy weeds and California grass but there are also beautiful ti leaf plants and small flowers. With some of the blades of California grass you can see some holes in them, also some blades have white flies on their blades. That is a good example of predation the white flies are taking in all the benefit and the blades of grass are dying getting eaten up. Also living in the stream there is an abundant amount of small fast moving fish, with the occasional sighting of a Crayfish hiding under big rocks. Some abiotic factors are defiantly the rocks in the stream. They provide excellent cover and a place to live in the stream. If there were no rocks then no fish would live in that area of the stream. One of the biggest and most obvious abiotic factors in that area has to be the bridge because there is so much shade and protection from the sun. The wildlife in the stream would more likely to live in an area with lots of rocks, overgrowing bushes and a bridge that provides lots of shade for all of the wildlife. When I visited the stream I immediately went to the water and I saw the most of the fish near or under the bridge hiding under the rocks or close to them. Also the only place where I could find a Crayfish was under huge rocks that provided lots of protection to ensure their survival in the wild. When you see the wildlife in the area you see nothing very interesting but if you walk around ground zero you can actually see some bird footprints and the plants with holes in them. This place would be good to study because it has so much life and is so alive. You can write so much about all the different kinds of predation the small fish eating the algae; the crayfish eat the dead fish and the plants getting eaten away on the land. You can also get really close and sometimes catch some of the animals in the water so it will make studying this area even easier then just observing from a distance.

One of the examples of the wildlife in the area happen to be the fish they live in the shade of the bridge or under some small rocks or leaves that have sunk to the bottom. These fish have lots of algae in there habitat and I have seen some of them with there head down moving there mouth so I thin that that is there main food source. One more predator to the fish is the crayfish; they prey of the dead fish. They live close by the small fish under huge rocks and by the upper side of the stream. So they live relatively close to the niche of the small fish. I have came once before and I have seen a crayfish eating one of the small fish so I think that is their main food source in their niche. As moved higher up the stream getting my feet wet I have found the California grass with holes in the lower blades. The as I moved my eyes up higher I have found some white flies or some thing that seemed to be eating on the blades of grass. This is an example of predation the flies have everything to gain such as a place to live and an abundance of leaves to eat. Also one hard to spot animal that may be arriving in the stream may by some kind of bird. The prints had a 3-pronged shape to them as the y walk along the bushes maybe looking for an insect to eat or maybe get a drink from the stream. This may look like a boring place but it had many examples of predation.
