Check out these sites.

http://www.extension.umn.edu/yardandgarden/ygbriefs/h140perennialdivide.html

These websites provide information about different aspects of plant population density and overcrowding in plants. The first link is from the Oregon State University Extension website, specifically their catalog on plant diseases. While plant diseases may not directly address overcrowding, it can provide insights into the effects of overcrowding on plants' health.

The second link is from the University of Minnesota Extension and provides brief information on perennial plants and how to divide them. Although it does not directly focus on overcrowded plants, it discusses dividing perennials, which can be a practical solution for managing overcrowded plants.

To find a website specifically dedicated to plant population density and overcrowded plants for middle schoolers, you may want to consider doing a more targeted search using a search engine like Google or Bing. Use specific keywords such as "middle school plant population density website" or "educational resources on overcrowded plants for middle schoolers."

Make sure to review each website's content to ensure it is relevant to what you are looking for and appropriate for your audience.
