At the beginning of the 20th century, the Kaibab Plateau was witness to an interesting experiment in what some might call population engineering. The plateau’s pre-1905 population of deer was estimated to be around 4,000. The average carrying capacity of the land was unknown, in part because this concept was not widely used by naturalists at the time. This activity asks students to graph the number of Kaibab deer on the plateau after predators were removed. Predators were removed as a way to increase deer populations, but may have had the opposite effect. Students read about the background of the Kaibab plateau, graph data, and then analyze the data. Follow-up discussions link the case to previous lessons on keystone species and carrying capacity.

I am a Biology teacher and I was looking for the answer key of The Lesson of Kaibab. Is it possible to share that with me?
I have that one posted at Teachers Pay Teachers. https://www.teacherspayteachers.com/Product/The-Lesson-of-the-Kaibab-Key-3804533
