Course Title:  Native vs. Nonnative Plants: Examining the Science Behind the Controversy

Delivery Method: Live Online 

Course Description: This two-hour course explores the ecological, scientific, and practical debates surrounding native and nonnative plants in landscape architecture in the Western US. Topics include definitions and terminology, the decline of native plant species and wildlife, biodiversity impacts of invasive species, and ecosystem responses to species introduction. The program also examines the actual versus perceived benefits of native plants and identifies the characteristics that make landscapes ecologically diverse.

Learning Objectives: 

Learning Objective 1: Learners will be able to define and differentiate between native and nonnative plants in ecological and design contexts.

Learning Objective 2: Learners will be able to analyze the decline of native species and evaluate the biodiversity impacts of invasive plants.

Learning Objective 3: Learners will be able to explain how ecosystems respond to the introduction of new plant species.

Learning Objective 4: Learners will be able to identify characteristics that contribute to ecologically diverse and resilient landscapes.
