Topics Explored: Rangeland Ecology, Land Use, Population, Biodiversity, Data Processing and Percent Change Analysis
This case study explores the history, ecological impact, and population trends of wild horses (Equus ferus) in North America. Students are prompted to choose a management practice and use evidence and reasoning to support their position. 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.
