Lessons on the Lake -> Chapter List -> Chapter 2 -> Activity: Where have all the Wetlands Gone?


During the last 200 years, we have lost 50% of our nation’s wetlands.

Louisiana’s coastal wetlands are vanishing at a rate of 20,000 to 25,000 acres per year. If this rapid loss continues, the Gulf of Mexico will be thirty-plus miles closer to New Orleans, and more of our bountiful marshes will become open bays of water. In this exercise, we'll discuss wetland loss and it's relationship to other issues in order to come up with some possible solutions.


  1. Copies of student handout
  2. Butcher Paper
  3. Pencils
  4. Markers

Procedure: (in groups)

  1. Each student in the group will complete the handout “Where Have All the Wetlands Gone?”. (see below)
  2. Students compare answers with group members and reach a consensus.
  3. Each group of students should make a large copy of the completed chart on butcher paper.
  4. Completed posters should be hung around the room as each group presents its results to the class.
  5. After a discussion period, a class consensus can be developed for a bulletin board display.

The use of pesticides in the U.S put pelicans on the endangered species list. Fortunately, they are now recovering.
