Trace Threats to a Wetland's Biodiversity
Written by Adi Ackerman, Head Teacher
"Trace Threats to a Wetland's Biodiversity" is written for 7th Grade (Ages 12-13), and it covers NGSS MS-LS2-4. A 6th grader who is already steady on ecosystems can use it too, and an older student can use it as a short review.

7th grade science worksheet: graph species counts over 30 years at a model marsh and link drops to a road, a reed and drought. Answer key included. Part of our biomes and biodiversity ecosystems collection. Aligned to NGSS standards.
How do I use this worksheet?
Use the mangrove sheet to practice sorting parts of an ecosystem, then the wetland and services sheets for evidence based claims. The wetland in the data sheet is made up as a model.
What students will practice
- Students will plot the number of bird, amphibian and fish species over 30 years.
- Students will mark four events on the graph and name the type of threat each one is.
- Students will write claims that use the species counts as evidence.

FAQ
How do I use this biomes and biodiversity worksheet?
⌄
Use the mangrove sheet to practice sorting parts of an ecosystem, then the wetland and services sheets for evidence based claims. The wetland in the data sheet is made up as a model.
What does this worksheet teach?
⌄
Graph species counts over 30 years at a model marsh and link drops to a road, a reed and drought. The directions on the page read: Read the record of the marsh and study the table. Then use both to complete page 2. An answer key is included.
Can I use this biomes and biodiversity worksheet for homeschool or classroom?
⌄
Yes, both. We made it for 7th grade ecosystems, and it works the same at home or at school. At home, a student can work through it alone and then go over it with you, which shows quickly what is solid and what needs another look. In class it works as independent practice, homework or a warm-up, and you can print one copy or a full set.
What threatens biodiversity?
⌄
The wetland sheet traces a road that splits habitat, a nonnative reed and a drought. Students link each event to a drop in species counts.
What are ecosystem services?
⌄
They are benefits that ecosystems give people, such as pollination, clean water, healthy soil and medicines.
What lives in a mangrove swamp?
⌄
The fact file describes salt tolerant trees with prop roots, along with consumers and decomposers. Students sort what they read into an organizer.
