Welcome Students!

FOR 141 and 241 are introductory courses that focus on tree identification.  They each include information on ecology, principal uses, and natural history of forest trees of the United States.  They also include skills that will enable you to identify trees and shrubs not learned in class, and to answer the kinds of questions that you’re likely to encounter in the future.  One is not prerequisite to the other; in fact, it would redundant to take both.

These classes are required for students in forestry, but they’re commonly taken by students from all over campus (for example: fisheries and wildlife, range, horticulture, natural resources, business, engineering, environmental science, philosophy, sociology, anthropology, etc.).  It’s not uncommon for a class to have more non-forestry students than forestry students.  If you want to learn how to identify trees, you’re welcome in either class.  
 
Both classes include two 50-minute lectures per week, one 2.3 hour lab, and one recitation period that serves as a lab exam period (more on that later).  Labs are generally guided “field walks” around campus that facilitate “hands-on” learning.  Through multiple testing opportunities, lab exams are structured to facilitate learning, as well as to assign grades.
