  Ecosystem Services
Ecosystem services are the natural processes that are responsible for clean air, clean water, healthy uncontaminated food and a host of other environmental goods that we tend to take for granted.
Ecosystem services can be damaged through ignorance, mismanagement or simply because there are no markets in which to trade particular services or their products.
The ecosystem services approach proposed in this study is an explicit attempt to measure both the biophysical and the economic implications of alternative management systems and to quantify trade-offs.

 Valuation of Ecosystem Services
Ecosystem functions are the physical, chemical, and biological processes or attributes that contribute to the self-maintenance of an ecosystem; in other words, what the ecosystem does.
Market failures related to ecosystems include the facts that: (i) many ecosystems provide services that are public goods; (ii) many ecosystem services are affected by externalities; and (iii) property rights related to ecosystems and their services are often not clearly defined.
Ecosystem services are often public goods, which means that they may be enjoyed by any number of people without affecting other peoples’ enjoyment.

 "Ecosystem Services: A Primer" from the Ecological Society of America (ESA)
Ecosystem Services are the processes by which the environment produces resources that we often take for granted such as clean water, timber, and habitat for fisheries, and pollination of native and agricultural plants.
An ecosystem is a community of animals and plants interacting with one another and with their physical environment.
Ecosystem services are so fundamental to life that they are easy to take for granted and so large in scale that it is hard to imagine that human activities could destroy them.

Ecosystem services are the transformation of a set of natural assets (soil, plants and animals, air and water) into things that we value.
Some other examples of ecosystem services that come from nature can be viewed in Chapter 7 of the Natural Assets Inventory Report.
Ecosystem services are little understood and too sophisticated for us to reproduce even with the most advanced technology, yet the important roles of these natural services are not being recognised adequately in economic markets, government policies or land management practices.

Ecosystems have a cast of characters – plants, mammals, reptiles, birds, fungi, bacteria, and other living things – each of which interact, or cooperate, antagonize, and help each other, the way people do.
The services that members of ecosystems provide also vary from place to place, be they the food we eat, medicines we discover, bats that curb mosquitoes, insects that pollinate fruit trees and crops, or trees that prevent soil from washing away.
Ecosystem services also include water purification and the regulation of the exchange of crucial elements between the ground, air, and water.

 Valuing Ecosystem Services
Some critics believe the effort to assign prices to ecosystem services is fundamentally flawed since these services can never be traded in open commerce, which is how prices of conventional goods and services are determined (Sagoff 1997).
The problem is that the value of services provided by the Earth's ecological infrastructure does not fit into current economic equations, partly because most of the benefits fall outside the marketplace.
Although the average value of wetland services may not be the same per hectare in Brazil, Indonesia, or Uganda, the very existence of the global estimates calculated in the study should broaden the context of local decision making (Pimm 1997:232).

 Natural Ecosystem Services
The goods, or products, these ecosystems provide—such as fish, wood products, and food—can be counted, and a monetary value often placed upon them (key ecosystem products are described in the production of food, fiber and water witdrawals indicator).
Some services, such as recreation, are also fairly easily quantified (see the national, farmlands, forest, fresh water, and grasslands and shrublands recreation indicators).
Since many ecosystem services are lost or exchanged for other, different, services when natural ecosystems are converted to farmland or urban/suburban use, or when wetlands are filled, tracking changes in ecosystem extent is the best way we currently have of quantifying changes in ecosystem services.
