Accurate Forest Inventory

The basics of practical and efficient
timber cruising, plus a great review for the NC Registered Forester Exam

Hampton Inn RBC Center - Raleigh, NC
December 15, 2011 - Introduction to Forest Inventory and Sampling

December 16, 2011 - Advanced Forest Inventory and Sampling


About the Workshop


This workshop will give timber cruisers, forestland managers, and appraisers the information they need to design accurate and efficient forest inventories. The instructor will explain the major methods of inventory cruising, including prism, fixed plots, and strips. Participants will learn to develop statistically reliable inventories and to make informed conclusions based on cruise results. The field exercise will provide opportunity for hands-on comparison of the various inventory methods. Emphasis will be placed on practical considerations with numerous applications and examples. This course will also be a comprehensive review for those planning to take the North Carolina registered foresters’ exam. Registration includes a comprehensive notebook with material covered in the course. Familiarity with forestry terms and concepts is assumed.

The course will be broken up in to two sections so that participants can choose which portions meet their goals. Section 1 will be an introduction to forest inventory and sampling course, while Section 2 will cover more advanced topics in forest inventory and sampling. If you do not have much experience with forest inventory techniques, then it is recommended that you sign up for both sections. Return to top of page.


Who Should Attend?


This course will be valuable to forestry consultants, engineers, landscape architects, appraisers, and regulatory professionals who are responsible for acquiring and analyzing stand-level information. Attendees at this workshop in the recent past have told us it was invaluable preparation for taking the NC Registered Forester Exam. It is recommend for professional appraisers and land surveyors as well. Return to top of page.


About the Instructors


Bronson Bullock is assistant professor of forest biometrics and timber management in the Department of Forestry and Environmental Resources at North Carolina State University. Bronson has been at NCSU for six years and teaches Forest System Mapping and Mensuration I, Forest Systems Mapping & Mensuration II at the forestry summer camp, and Forest Measurements, Modeling, and Inventory in the undergraduate curriculum; he also teaches graduate level courses on Advanced Forest Modeling. Bronson has a B.S. in Natural Resources Management – Forestry from Rutgers University, M.S. in Forest Biometrics, M.S. in Statistics, and Ph.D. in Forest Biometrics from Virginia Tech. His research interests focus around traditional and upcoming techniques in forest biometrics (volume and taper equations, weight equations, growth and yield modeling, spatial statistical applications to forest inventory and modeling, etc.) Return to top of page.


Lodging and Transportation

The workshop will be held at the College of Natural Resources, NC State University in Raleigh, NC. A map with directions will be included with your registration confirmation letter. Lodging is not included in the registration fee, however, rooms have been blocked at the Ramada Inn Blue Ridge Road. To make a reservation call 919-832-4100 before December 1st and mention that you are with the group “NCSU Forestry ”. Transportation is provided to and from the nearby field site on Thursday, December 17. Return to top of page.

 

Equipment

Attendees should bring a calculator. For Thursday's field trip we will utilize hard hats, BAF 10 prism, loggers tape, D-tape, compass, and clinometer. Instructors will be bringing field measurement instruments if you don't have your own. Laptops will be provided, but students wishing to bring their own laptops may do so. Be sure to wear appropriate field attire, and bring rain gear. Return to top of page.
