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

    In the Alaskan Tundra, abiotic factors include wind, temperature, and sunlight. Abiotic factors are nonliving things that influence or affect the ecosystem and the organisms in it. Factors such as wind, temperature, and sunlight can have a lasting effect on an ecosystem such as an Arctic Tundra. In the Alaskan Tundra, strong and persistent winds rush through the air.…

    Being a coniferous area of woodland the main tree species are: pine, larch, birch and spruce. Some of these trees (spruce and pine) are adapted to the climate by having smaller, prickly leaves with waxy cuticles to reduce water loss and do not defoliate in winter. The advantage of this being that the trees may take in all the available sunlight for photosynthesis. The branches on such trees tend to be slightly elastic and bend under the eight of snow causing it to fall off and expose the leaves to the sun. The trees also have very shallow roots due to the continuous permafrost that restricts growth and also slows down the nutritional development of the soil.…

    Because of the short summer of the Arctic tundra and harsh conditions, the Arctic tundra has very few plants and trees. Because the summer is short, the trees are unable to grow larger. The strong winds damage the trees and the permafrost makes it hard for trees to create a strong support base. The plants and trees that can be found in the tundra are lichens, mosses, and small shrubs. The plants that can survive in the tundra are short and grouped together to resist winds and to be protected.…

    These grasslands have hot summers and cold winters. Summer temperatures can be well over 100 degrees while winter temperatures can be as low as -40 degrees. They typically have between 250 and 850 mm of precipitation a year most of it occuring in the late spring and early summer. Grasses are the dominant vegetation in this biome there are few trees and shrubs due to Seasonal droughts, fires and grazing by large mammals all keep large vegetation number down. Temperate grasslands have a low diversity of wildlife, but a high abundance of wildlife.…

    The natural vegetation regions and soil regions are interconnected in numerous ways. Soil regions as the Tundra soils, or dry climate soils have the potential to affect the type of vegetation that can be grown. Where you would find cold temperatures as the Tundra, you can expect limited vegetation to grasses, mosses, and shrubs. Because the ground has an active layer of permafrost, growing conditions are not suitable for plants and trees. Areas with moist soil as the wet-climate regions, you are expected to find trees and plants resembling the mixed forests, boreal and taiga forest, as well the deciduous forests. The Grasslands are located in the dry climate soils situated in the Prairie Provinces. Due to the dry temperatures there are very insufficient amount of trees, and consisting of large rolling terrains of grasses. To conclude location is a dependent factor on the type of vegetation a region will come to…

    Drylands are characterized by water scarcity stemming from the conjunction of low water offer (i.e., precipitation) and high water demand (i.e., water lost to the atmosphere as water vapor from soil via evaporation and from plants through transpiration). Drylands ' precipitation is highly variable through the year and occurs in infrequent, discrete, and largely unpredictable events. In turn, the high evaporative demand of the atmosphere, resulting from high air temperatures, low humidity, and abundant solar radiation, determines that water availability is the dominant controlling factor for biological processes such as plant growth and herbivore productivity. Thus drylands, though not barren, are ecosystems of low and highly variable productivity capable of limited human settlement and vulnerable to anthropogenic disturbance.…
