The study explores the different types of trees in the different environmental ecosystems. The trees are distributed everywhere both in private and public land. There is a difference in their heights their physical appearances and even the smell or aroma which they emit. Some of the trees have bloomed and their different flowers have attracted various birds and even insects including butterflies and bees. From the different presentations and distributions, it is evident that there is an extent of variation in the types of trees across the ecological gradient. The difference lies in the species varieties, their color, heights, flowering and fruiting seasons, and the distribution both in the private and public areas. There are more than 100 species of trees within the region. A majority of them fall in the genus Eucalyptus. In as much as initially, oaks were the predominant species, the genus Eucalyptus is rather a majority within the region. The other types of trees include oaks, cones or rather cedars, Magnolia, Pine, cypress, palms amongst others. The tallest tree which is also the oldest is an Old Coast Redwood from which the town was named after. However, the redwood are very few as compared to the presumption that they would be numerous within the environmental gradient. The different types of eucalyptus have different features and also florals which bring forth the beauty of the area. The pines and other canopy trees create canopies that provides shade for humans. Eucalyptus trees consists of approximately 60 species (including E. acaciiformis,E. caesia, E. laeliae, E. maculosa amongst others) pine trees have about 30 different species(including P. eldarica, P. jeffreyi, P. mugo, P. sabiniana P.nigra amongst others) whilst the cypress consists of 7 different species which include Cupressus (C) arizonica, C. macrocarpa, C.torulosa, C. funebris amongst others. One of the hypothesis to be tested was whether human encroachment and population growth within the area affects the different types of trees within the area.
