The food web in Richmond is very small. Due to the lack of wildlife, there is not very many, if any predators in the area. The largest predators are domestic cats, there are no snakes, deer, foxes, wolves, or any other predators that roam free in large, open areas like Novato. The most dominant decomposers in Richmond are worms. They have a very strong presence in my garden, and in the gardens near our house. The insects that dominate are aphids, which are then eaten by the ladybugs. There are also dragonflies, beetles, bees, wasps, and the occasional preying mantis in the garden as well. The birds feed on all of the different types of insect, and sometimes a cat will kill and eat a bird. The biodiversity in Richmond mostly comes from plants, not from animals. There are many, many different types of plants in the area that are native, and non-native as well. Compared to the amount of biodiversity that the california floristic province had, Richmond is a very disappointing city. There are not lots of different trees, or animals like the CFP has. Humans have had a profound effect on the biodiversity in Richmond. The removal of all of the wild plants during the industrialization made many species rapidly disappear from the city, leaving only the animals that were fit to survive still in the area. We have also had a large effect on the CFP. The way that we have treated such fertile land has lead to it being really tough to restore it to its natural state.
Native plants are very helpful to an ecosystem. Plants native to any area support the wildlife that is native, giving the animals food and shelter in a plant that they are familiar with. When an area has lots of native plants, the area usually thrives because of the natural balance that the plants and animals have with each other. Plants and animals that are both native to a certain area easily coexist, so the area thrives. On the contrary, non-native plants are often invasive. This means that the plan spreads extremely quickly, and often kills off native plants and animals by taking the sun, and root space from the plants, leading to the death of the native plant. This eventually will kill the native animals because they do not have shelter, and cannot quickly adapt to a new environment. The only naturally occurring body of water near my house is the Pacific ocean. But one body of water has a large effect on my town, and the surrounding areas. I live about 10 minutes away from the
San Pablo Reservoir. This reservoir supplies water for Richmond, and most of the rest of the east bay as well. The reservoir's levels had been very low for the last four, or five years, but with the heavy rains of late 2010, and early 2011, the reservoir overflowed for the first time since 2006.
