General Environmental Science Science Fair Project

The Impact of Plant Communities

The Impact of Plant Communities | Science Fair Projects | STEM Projects
Are you curious about how the environment around us is affected by the plants we choose to grow? In this project, you will explore the impact of different plant communities on biodiversity.


The hypothesis is that biological communities that contain a greater variety of plants will have a higher biodiversity in the form of species richness.

Method & Materials

You will identify two very different biological communities, measure three plots of land in each, and take an inventory of all the species within the boundaries.
You will need a tape measure, string/yarn, sticks, a camera or sketchpad, and a magnifying lens.


After completing the experiment, you will have a better understanding of how different types of plants can affect the biodiversity of a region. One observation that stands out is that plants are often critical components of communities because they form the base of the food web, as well as provide living structures and microclimates for other organisms in the community.

Why do this project?

This science project is interesting and unique because it allows students to explore the impact of different plant communities on biodiversity in their own environment.

Also Consider

Variations of this experiment could include measuring the biodiversity of aquatic environments or measuring the biodiversity of different types of soil.
