Catalog Description Also known as AGRI 0163 Advisory: Eligibility for ENGL C1000 Hours: 108 (54 lecture, 54 laboratory) Description: Study of the botanical characteristics, taxonomy, and physiology of major trees and shrubs of the Western United States, with emphasis on California. Covers plant community relationships, geographic ranges, and human impact on forest ecosystems. Includes identification of specimens in the field and use of herbarium samples. (CSU) Course Student Learning Outcomes CSLO #1: Use dichotomous keys and field guides to identify the family, scientific, and common names of major tree and shrubs in California forests. CSLO #2: Evaluate the ecological requirements of common forest trees in North America, with an emphasis on California. CSLO #3: Describe and differentiate the value, uses, and geographic distribution of common trees and shrubs in the Western United States. CSLO #4: Explain the relationships of forest species to the evolution and ecology of global forest ecosystems. CSLO #5: Classify plant species to develop a curated plant collection.

Identify morphological features of trees and shrubs for classification and binomial nomenclature. 2. Describe the ecological requirements of common forest trees and shrubs in North America, with emphasis on California. 3. Recognize distinguishing characteristics of common forest community types in the Western United States, focusing on California. 4. Explain the relationships of forest species to forest successional history. 5. Compare the value, uses, and geographic range of common trees and shrubs in the Western United States, with emphasis on California. 6. Analyze human impacts on forest ecosystems. 7.

(Lecture Objective #3) Identify and describe the ecological requirements of 5 trees in the lower mixed conifer forests. (5 points - 1 point per described tree) Skill Demonstrations Example: 1. (Lab Objective #3) Using the dichotomous key, identify the unknown species at your lab table, detailing all of the steps you took in order to come up with your identification. (10 points for correct identification, 1 point for every correct step in the dichotomy) Repeatable No Methods of Instruction Laboratory Lecture/Discussion Distance Learning Lab: Using live stem/leaf specimens, the instructor will demonstrate how to identify plant characteristics and assign proper botanical terminology. Students will observe 15 specimens and record appropriate terms on a reporting form. For example: Leaf type, shape, base, tip, margin, venation, attachment, arrangement. (Lecture Objective 1, Lab Objective 1) Lecture: Instructor leads discussion of environmental characteristics associated with various forest communities or ecosystems. Following the discussion, using herbarium or live samples and prior knowledge of tree/shrub species, students work collaboratively in small groups to determine which species are suited to each ecosystem. Groups will explain how they derived their answers. Lecture objectives 2, (Lab Objectives 3 & 6) Distance Learning Following an online lecture on the uses of common trees and shrubs in the Western United States, students will debate ideas on a discussion board with their colleagues. They will also post evaluative papers to the board and critique papers posted by their colleagues. Students will be required to respond to a minimum of 2 other students’ initial responses. The instructor will create accessible content. Instructor will incorporate engaging tools to facilitate content delivery, keeping student equity, success and accessibility as the foundation for tool selection. (Lecture Objective 3) Typical Out of Class Assignments Reading Assignments 1. Read field guides and practice using dichotomous keys to reinforce knowledge of plant terminology and assist in the identification of plants. 2. Read current research on the effects of climate change on forest species distribution. Synthesize the information and summarize in a logically developed essay. Writing, Problem Solving or Performance 1. Read a current research article pertaining to negative human impact on forest ecosystems. Summarize the research, and list the pros and cons of potential solutions or mitigation strategies pertaining to the problem. Present an oral summary before the class and answer questions. 2. Field notebook: Identify plants and key characteristics in the field using proper taxonomy and terminology; record site elevation, location and plant community type; determine successional stage; assess plant diversity and density; list evidence of human impact; identify invasive species, pests/diseases, and other indicators of forest health. Other (Term projects, research papers, portfolios, etc.) Students will create a herbarium of 50 plant specimens identified throughout the semester. Accompanying text will include proper taxonomy and habitat specifics.
