Essential ecosystem services

== Ecosystem Services ==

-David McClenaghan

Ecosystem Services are the documentation of the values and the benefits derived from ecosystems and the natural resources provided by the services. Ecosystem services are the benefits humans gain within marine and terrestrial ecology. For example, timber, clean water, food, and various cultural values. These services can be classified into four categories, provisioning services, regulating services, supporting services and cultural services.

Services of Ecosystems

Provisioning Services: These services provide the ecosystem and it's inhabitants with energy and material. They provide essential materials and energy through the output of productivity and these can be any types of useful resources, like food or water. An example of this would be in developing countries, there is a heavy reliance on natural medicinal plants and these plant materials are provided by an ecosystem. Another example of provisioning services would be the conditions an ecosystem has that allows it's inhabitants to be able to obtain food, whether this is from growing it, collecting it, hunting it, harvesting it, or from a plants perspective, producing it. The conditions an ecosystem may have would be the amount of rainfall per "wet" or "dry" season. This would directly affect the quality of soil of the ecosystem and thus affecting the type of flora and provisioning services within the ecosystem.

Regulating Services: Are the services that act as managers, maintaining the quality of air, soil, and other parts of an ecosystem. Regulating services also provide flood and disease control. An example of regulating services is Carbon Sequestration and storage. This occurs when trees and plants grow, they utilize and remove CO2 from the atmosphere. This regulates the amount of carbon dioxide in the atmosphere, provides an ecosystem with oxygen and manages change in temperature.

Supporting Services: Are the basis to all ecosystem services, they provide a place to live for plants and animals, while a strong diversity between plants and animals. An example of supporting services is maintenance of genetic diversity. This is how we conserve and protects unique species and maintain the diversity of species within an ecosystem. A large portion to maintenance of genetic diversity is documentation, because if a species is nearing what classifies as "Endangered," then action needs to be taken right away.

Cultural Services: Are the non-material benefits that humans gain from an ecosystem. This can be artistic and aesthetic inspiration, cultural identity, spiritual experiences with the natural environment and even a feeling of being at home. An example of cultural services is aesthetic and artistic appreciation. Art, culture and even science has been heavily influenced by biodiversity, natural landscapes, and ecosystems. Also, language, knowledge and our natural environment have been interconnected throughout the history of humans.

Example :Soil Formation

Soil is extremely important to an ecosystems biodiversity and plays a role in the productiveness of the ecosystem. Soil Formation is a supporting service because supporting services are the services that are fundamental to the productions of all other services. Soil is incredibly heterogeneous and varies from place to place. For example, it has different characteristics from country to country and even from town to town. An important factor to understanding soil formation, is understanding what parent material is. Parent material are rocks, that have been broken down, due to either physical, chemical or biological weathering. The important factor is that when there is parent material present, and along with dead organic matter, microorganisms, plants and animals, soil can be formed.

Hans Jenny, a major influence in soil ecology, coined the term "Pedogenesis" or soil formation. He furthered how we view soil formation and created an equation displaying factors of soil is formed and this equation is called the Jenny Equation:

-Ruth Heindel

S=f(cl,o,r,p,t,...) Soil=Formation(Climate, Organisms, Relief or Topography, Parent Material, Time, ...)

-Food and Agricultural Organization of the United Nations.

Soil Formation directly and indirectly affects other processes and benefits within an ecosystem. The chart below, gives the processes and benefits within each ecosystem service that is directly or directly affected by soil formation and these are specific to Southeast Queensland in Australia. The processes and benefits closest to "5" are the strongest relationship and can be described as occurring as a direct result of soil formation. Three benefits from ecosystem services fit within "5" or the strongest direct relationship, arable land or land that is ideal for growing crops, food products, and productive soil. Most benefits and processes are related and interconnected in some way. For example, if quality soil forms within an area, the productive natures of the soil will be high and in most cases this makes for arable land or ideal conditions for growing crops. This is why for Southeast Queensland, there is a direct relationship between soil formation and the productiveness and land use of the region. Soil formation and the rate of production in soil will always strong relationship due to the fact that they have very similar factors that mold each other.
