Topics Explored: Ecosystems, Population, Percent Change, Gather-Reason-Communicate with Evidence
This case study explores the the decline and rise of the American black bear (Ursus americanus) population in New Jersey, their interactions with people in America’s most densely populated state, cultural carrying capacity, and the dilemmas faced by the New Jersey Division of Fish and Wildlife. Answer key included.

(1 Teacher Edition and 1 Student Edition)Next Generation Science Standards (NGSS):
HS-LS2-1. Use mathematical and/or computational representations to support explanations of factors that affect carrying capacity of ecosystems at different scales.
HS-LS2-2. Use mathematical representations to support and revise explanations based on evidence about factors affecting biodiversity and populations in ecosystems of different scales.
HS-LS2-6. Evaluate the claims, evidence, and reasoning that the complex interactions in ecosystems maintain relatively consistent numbers and types of organisms in stable conditions, but changing conditions may result in a new ecosystem.
HS-ESS2-7. Construct an argument based on evidence about the simultaneous coevolution of Earth’s systems and life on Earth.AP® Environmental Science Learning Objectives:
