Case Study: The San Joaquin Valley

he San Joaquin Valley is the area of the Central Valley of California. It covers 7 counties which are Kings, Kern, Stanislaus, Merced and Fresno. The San Joaquin Valley is known as the #1 producing region in California for its variety of fruits and vegetables grown in its fertile soil. The Valley is 250 miles long and bordered on the west by the coastal mountain ranges.
Even though a lot of the valley is rural there are a lot of urban cities here in the valley. I want to tell you about the five different biotic communities in the valley, how they’re made up,the quality of our air and what we as people can to due to save water.
The valley grasslands main abiotic factor come from the climate and the parental material and soil. The climate can
Riparian sediments are fine in their ability to hold nutrients. When these two environmental factors come together, there is or can be a growth in a complex vegetative community. Surrounding riparian zones are typically grasslands and they get their source of water from the groundwater in riparian streams. The temperatures in riparian zones fluctuate and are dangerous for biotic life that depends on an acceptable temperature ranges for the vulnerable individuals in the habitat. The appropriate water temperature from riparian streams comes from the morphology that play a crucial role for maintaining that temperature.
Chaparral is a mostly dry type of biotic community. In the central valley, it is dry and in the summertime, it can get to be about in the 100s, so the valley is known for how hot it can get. We hardly get rain coming into the valley and having little or no rain is a factor in why chaparral is grown. The average precipitation is no more than 30 inches a year that this biome community receives, so it is more or less
These trees typically grow in alkaline soils but they do not live long. The fog in the valley contribute to the pine forest’s ecosystem and helps it stay alive. Yellow Pine has a montane ecosystem because it is located in the mountains.
It stays in colder climates because it is in a higher elevation point. The reason why these trees are still here today is because throughout the years, they adapted to the environment and specialized in growing under certain conditions, living in areas other trees cannot survive in. During the fall and winter time, the mountain range gets cooler and these trees survive that climate change, so they have an advantage over other trees.
The reason behind all these different biotic communities and why they’re the way they are now comes from the Pacific Ocean. The hot air that moves inland towards the coastal range carries hot air that comes from the ocean onto land where it is very wet. That is why most places by the coast are cool for the most part. When that same air goes up and over the coastal range the air gets cooler. When that air is in the coastal range it will rain and when that rain stops is when that air comes down from the coastal range into the
