What this Lesson Covers
Plant density and frequency are relatively easy to measure
and can give a land manager a good idea of how the plant
community is changing. However, it is often important to
know what plants are actually controlling the resources on a
site and covering the soil. Plus, it is often necessary to
measure a plant attribute that will allow comparison of plants
across species and growth forms. The solution to these
challenges is the assessment of Vegetative Cover.
In this module, we will explore different types of Cover and overview
guidelines on how to apply several techniques designed to asses cover.
And, yes, there will be a few tips to assist with analysis.
After this module you will be able to:
the value of measuring plant cover to describe ecosystem function and assist
in making land management decisions.
the difference between ground, basal, foliar, and canopy cover.
the basic approaches to point-, line-, and plot-based methods for assessing
Summarize cover data
to compare plant
communities over space and time.
