Quadrats

Can you count all of the trees in your yard? How about all of the flowers? All of the blades of grass? It would take a really long time to count each individual plant. Instead, scientists take samples of a small area in order to estimate the distributio(n of a species over a large area. One device that scientists use to analyze the number of organisms found in an environment is called a quadrat. Ecologists use a quadrat, traditionally a square shape, to count the number of plant and animal species in a particular area. For example, rather than counting all of the crabs on the rocky coast, just a few samples taken with a quadrat can help scientists estimate the number of crabs on a particular beach. By comparing multiple samples, scientists can track how species populations change over time. Quadrats are also a good tool to use in order to zoom in on a particular area in order to observe nature, and make comparisons between different locations. Learn more about how to use a quadrat, and how to create your own, with Program Coordinator, Emma:

Now, create your own science experiment! Use your new quadrat to collect data and answer a question about your environment using the Backyard Scientist: Quadrat guide. Share a picture of your quadrat, or any exciting plant or animal species you find in your explorations to e.carey@sscnh.org to be posted on our social media.
