Woodlands/ Chaparral

Eden Caruso & Abbie Ruth Period 8

Woodlands/ Chaparral

Chaparrals can be found from 30° to 50° N and 30° to 40° S latitudes. The chaparral climate occurs in central and southern coast of California; the coast areas of the Mediterranean Sea; coastal western and southern Australia; the Chilean coast in South America, and the Cape Town region of South Africa.

Abiotic Factors

In the winter the Chaparral climate, also known as the Mediterranean climate, is mild and moist, but not rainy. During the summer it is very hot and dry. The temperature is usually mild but it can get very hot or nearly freezing. The temperature range is between 30° and 100° F. This biome only gets about 10-17 inches of rain all year, and most of it comes in the winter.There are many fires in the chaparral because of the heat and dryness. Chaparrals exist in a mid-latitude climate and lie in a belt of prevailing westerly winds. This is why chaparrals tend to be on the west sides of continents. It is classified under Köppen's climate classification system as Cs. The C stands for warm temperature climates, where the average temperature of the coldest months is 64° F. The s stands for a dry season in the summer of the hemisphere it is in.

Climatogram of Chaparral

As temperature rises to its peak the precipitation level is at its lowest. As the temperature cools precipitation levels rise.

5 major autotrophs, 5 major heterotrophs, and 3 decomposers and/or scavengers

Autotrophs: Big-berry manzanita (Arctostaphylos glauca), Ceanothus (Ceanothus tomentosus), Scrub oak (Quercus berberidifolia), Chamise (Adenostoma fasciculatum), and Silk-tassel bush (Garrya flavescens).

Heterotrophs:American coyote (Canis latrans), gray fox (Urocyon cinereoargenteus), Roadrunners (Geococcyx californianus), valley quail (Callipepla californica) , and Bighorn sheep (Ovis canadensis).

Decomposers/ Scavengers: Desert pack rat (Neotoma sp), Tent caterpillars (of Malacosoma), and the California mantis (Stagmomantis californica)

Describe the state of the particular biome area you are researching in terms of its preservation, degradation, or environmental status in general. Is it an area with deforestation problems? Are there national parks or nature preserves in the region? Are there specific dangers for the region that likely to be seen in the future? Are there any current environmental problems that are problematic for the region today?

Deforestation is the permanent destruction of indigenous forests and woodlands. In the Woodlands, there are many national parks such as Parks Victoria and Woodlands Waterfront Park. Also, the woodlands have a variety of nature preserves such as George Mitchell Preserve, Montgomery County Preserve, Old Riley Fuzzel Road Preserve, etc. An example of a environmental issue the woodlands face is an estimated 200,000 hectares of forests and woodlands are cut down each year due to tobacco farming. The main problematic issue in the woodlands today is cutting down trees, which affect the animals and their way of living.

Research and list any programs or groups that are taking a proactive role in helping to preserve the biotic or abiotic resources of your biome of study. These programs or groups may be very localized grassroots efforts, volunteer groups, privately funded preservation groups, or even government backed programs.

There are many programs that are taking a proactive role in helping the woodlands region. For example, Sonoran Desert Network Inventory and Monitoring Program, which helps this region preserve the abiotic and biotic resources and makes sure that the region continues to be out of harm and provide for the organisms in the area.
