Course Description: Silvicultural and botanical characteristics, identification, classification, range, and uses of native forest species of the United States; emphasis on plants of economic importance to forest practices in California and the western United States.  Field trips may be required.

 

Course Objectives:

After completing this course each student should be able to:

1)     Demonstrate a general knowledge of the science of Dendrology and understand its relevance to professions in forestry and natural resources,

2)    Demonstrate general knowledge of all genera of the major forest trees in the United States,

3)    Demonstrate specific knowledge of major softwood (gymnosperms) forest species in the Western United States,

4)    Demonstrate specific knowledge of major hardwood (angiosperm) tree and shrub species in California, Oregon, and Washington,

5)    Demonstrate an understanding of the concepts of dichotomous plant key design and use,

6)    Demonstrate an understanding of the interrelationships existing between soil, geology, climate, humankind and plant cover,

7)    Understand and appreciate the diversity and complexity of the California flora in relation to other western states,

8)    Recognize introduced ornamental or exotic trees in relation to native forest species,

9)    Understand the techniques of collecting, processing, and mounting plant specimens.

 

Rules:

1.     Cheating will not be tolerated and will result in immediate failure (F) for the course.

2.     Turn off your cell phone during lecture and lab.  No text messaging during lecture and lab.  Don't even look at your cell phone during class time.

Participation in lecture and lab is mandatory and will be monitored  (attendance will be taken on random days when I remember to) and figured into your final grade.

 

Exams will be in two parts.  A take home portion consisting of a choice of questions (you pick 3 of 5) will be distributed the period before the scheduled day of the exam.  This portion is worth 45 pts, is open book, and you are encouraged to use a variety of resources, but you must work alone.  You may use the take home exam during the in class portion of the exam.  The take home portion of the exam will be due the day of the exam before lab starts at 2:40 PM.  Late take-home exams are marked down 1pt/minute late.  The in class portion of the exam is worth 55 pts, and consists of short answer, multiple choice, and matching questions.  Spelling of scientific terms is very important and will be counted when your tests are graded.  Tests will cover the material discussed in lecture, activities, and corresponding text readings. The three lecture exams will not be cumulative.

 

White Mountains Field Trip: This is a required three-day field trip to the White Mountains to observe the ancient bristle cone pine in the high desert mountains of eastern California.  The dates of the field trip are October 5th through the 7th.  More details on the field trip will be given early in the semester.  This field trip substitutes for the regularly scheduled laboratories during the 1st, 10th, 12th, and 15th weeks.  The White Mountains field trip is worth 50 points.

 

Plant Collection: Each student will be responsible for submitting a collection consisting of a minimum of 25 plant species indigenous to this locale.  All specimens must be carefully mounted and correctly identified.  Instructions for preparing the collection must be followed carefully in order to receive full credit.  Collections must be submitted by the 15th week and will be accepted earlier if convenient to the student.  Worth 100 points.

 

If you have an emergency, contact me prior to an exam.  Make-up exams will be given under extenuating circumstances only and will require written documentation validating the reason for missing the exam (e.g. Doctors note).

 

Field trips:

When we go on field trips you have to provide your own transportation.  We meet at the site of the field trip.  Carpool.  Field  trips may take either lecture or lab time or both.  Longer field trips on the weekends may require not having class some week.
