Overview

Ecosystem services are naturally occurring. They range from goods that are bought and sold to feelings of wonder and enjoyment. If damaged, they are difficult to return back to normal and could have economic as well as ecological ramifications.

Supporting

These services are necessary for other services to function. Photosynthesis allows plants to grow and therefore provide habitats and food. The biogeochemical cycles move the elements and molecules in order to support the existence of the ecosystem.

Provisioning

Think of the word provisions. Many of these services can be traded in markets or used in households. Services include food, water, shelter, medicine, energy, and timber (used for lumber).

Regulating

These services are often taken for granted because you do not see them in action. They are considered to be ‘behind the scenes’. Examples:
Air quality
Carbon sequestration
Natural disaster control
Pollination
Biological control
Erosion prevention
Water flow
Wastewater treatment

Cultural

Happy thoughts and feelings are provided by these eco-services. Many national/state/local parks are used for tourism, recreation, or aesthetic beauty.
