The objective of this activity is to assess the biodiversity in a two-meter plot sample of grass. This can be done either as a class in small groups, or as an individual activity.
|Lagoudou uses a lens to discover |
First, randomly select and measure a one-meter plot of grass.
Next, quantify how many different kinds of organisms inhabit the plot.
List as many different kinds of organisms (e.g. grasses, bugs, flowers, animals, etc.) you can find and make sure you describe and/or list the names of them and how many you find. For a basic assessment you can use simple terminology to classify the organisms (e.g. black beetle, small green grasshopper, thick sharp grass, etc.). For a more scientific approach you can use a dichotomous key (you should be able to find one in the library) and classify the organisms taxonomically (e.g. Gomphus vulgatissimus, Hesperioidea, Orthoptera, etc.).
- Which organism is most abundant in the plot?
- Draw the most common organisms on another piece of paper.
- How many different kinds of insects did you find?
- How many different kinds of plants did you find?
- What is the biggest organism found in your plot?
- What is the smallest organism found in your plot?
- Do you feel your plot of grass is biologically rich in diversity, or that it is lacking in species diversity? Why?
- What are the possible threats to your plot? What could be done to protect the biodiversity there?
