Synopsis
- In this article, students will read about ecological succession, primary forests, and why it's important to protect them.
- The article includes a diagram of ecological succession and an interactive map that allow students to explore where the remaining tropical primary forests exist on Earth.
Teaching Materials
Positives
- Terms and statistics used throughout the article are hyperlinked to scientific papers or websites to provide definitions, additional information, or context.
- The interactive map showing the locations of remaining tropical primary forests is a great visual tool.
Additional Prerequisites
- Students should be familiar with the terms ecology, ecosystem, and species.
Differentiation
- Students can further explore the map by clicking the link to "Explore on GFW" which takes you to a more detailed version with many layers, including different types of land cover, fire alerts, land use, and biodiversity options.
- The diagram and map could be used in lower grades when discussing geography and ecological succession.
- Higher grades could use the article to discuss the importance of old-growth forests for biodiversity.
- Cross-curricular connections can be made with math classes by challenging students to calculate the percentage of old growth/primary forests that have been lost.
Students will understand the concept of ecological succession to help in developing strategies for improved forest regeneration. The resource including mapped data points is accurate and recommended for teaching.
