What this Lesson Covers
Overview
So far in this course we have learned that several attributes
can be measured to describe vegetation communities. These
include:
- Density
- Frequency
- Cover
- Biomass
There are several ways that these individual attributes can be combined
to create descriptive measures of plant communities. These include:
- Dominance
- Diversity
- Composition
- Similarity
This module overviews approaches and protocols that combine individual
attributes to create a few commonly used measures to describe plant communities.
Learning Objectives
After this module you will be able to:
-
Explain
how
individual measures of density, cover or biomass can be used to calculate
composition of a plant community.
-
Calculate and evaluate common values for biodiversity in plant
communities.
-
Describe the ways
that diversity and dominance are used to evaluate plant communities.
-
Understand
how the similarity between plant communities can be used to assess and
describe habitats.
-
Explain
the concept of a "referent" used in monitoring
and assessment.
