  1. Measuring Biodiversity

  2. What Is Biodiversity? • The term biodiversity comes from the words biological and diversity. • It refers to the variety of life, and includes all living things (plants, animals and micro-organisms) and their unique characteristics. 1. What is this bird?

  3. What Is Biodiversity? • It can mean the variety of habitats, living communities and ecological processes in an ecosystem. • It can mean the diversity of genetic characteristics within a species. • It can mean the variety of species in a given area. 2. What plant is this?

  4. Why Is Biodiversity Important? • Ecosystems depend on the combined contributions of the individual organisms within them. The loss of any species can prevent that ecosystem from operating the way it should. • An ecosystem with a high level of biodiversity is more resistant to environmental change. 3. What kind? 4. Male or female?

  5. What does biodiversity mean to you? What does it mean to our Restoration Project? Why should we preserve biodiversity?

  6. Biodiversity Index 5. What kind of butterfly is this? • A biodiversity index is a way of measuring biodiversity. • Scientists use different biodiversity indices to measure diversity. • For some conservation questions, more than one measure may have to be used.

  7. Biodiversity Index • Brainstorm at least one idea of how to measure biodiversity in the prairie here at Chatfield? • Species Richness • The total number of species in an area (add them up!) • The most common type of biodiversity index is species richness, which refers to the number of species in a particular place. This measure is commonly used because most people have an idea what “species” means. • It is also commonly used because species keep their genes more or less to themselves, and to that extent have their own unique history. • Species Evenness • How evenly the species are represented in the area. • E.g., Do most of the individuals belong to one species?

  8. What is Conservation? • Supervision of rivers, forests, and other natural resources in order to preserve and protect them through management. • How is conservation related to biodiversity? 6. What kind of grass is this?

  9. Conservation Questions • Which measure—species richness or species evenness— is more important to conservation? • How is conservation related to our Restoration Project? • Develop your own way to apply conservation of biodiversity to the Chatfield prairie. 7. What bird is this?
