A Review of CFEOR Professional Workshops, 2009 (Part 2) By: Melissa Kreye, CFEOR Coordinator

In our last issue we reviewed the workshop, Biomass Harvesting

Demonstration offered April 30th, 2009 at the Osceola National Forest

(ONF) in Olustee, FL. In this issue we will re-cap the workshop, Uneven-

aged Management and the Proportional-B Method for Implementing

Selection Silviculture presented July 25, 2009 at Tate’s Hell State Forest

(THSF) in Carrabelle, Fl. Both professional workshops have been

approved by the Society of America Foresters for Continuing Forestry

Education credits. If you attended either of these workshops and

would like to receive credit please contact Melissa Kreye at

mkreye@ufl.edu.

At the uneven-aged management workshop Edward Loewenstein,

Associate Professor of Forestry at Auburn University, discussed the

history of uneven-aged silviculture, it advantages and the difficulty of

applying uneven-aged management using modern approaches.

Loewenstein stated there is an

increased demand for a wider

application of uneven-aged forest management methods that will

maintain continuous canopy cover, conserve wildlife habitat and

sustain ecosystem services. He further stated that traditional

approaches, such as diameter limit cutting (DLC), volume-guiding

diameter limit (VGDL) and basal area-maximum diameter-diminution

quotient (BDq), have long-standing disadvantages such as an

increased risk of "high-grading", are too complex therefore slow to

apply, require highly trained and experienced field staff and are more

expensive per unit area than other methods.

Lowenstein and Dale Brockway, Research Ecologist at the USDA

Forest Service Southern Research Station, presented a new method,

Proportional-B (Pro-B), which would streamline the application of

uneven-aged management procedures. Lowenstein describes the

Pro-B Method as a single-pass technique that simplifies application, yet

maintains adequate structural and compositional control of the residual

stand. It is quantifiable and produces consistent results across a range

of forest stand conditions.

The workshop focused on training attendees in the use of the new Pro-

B Method, including the new Pro-B Calculator which automatically

computes tree marking guides from basic stand cruise data. Brockway

inserted stand data from the CFEOR Signature Project, “Adaptive

Management Strategies for Ecosystems in Transition” located at THSF,

into the Pro-B calculator as an example of how the tool could be

applied. Brockway also presented photos from Goethe National Forest,

Blackwater River State Forest and other research sites that had

implemented the Pro-B method. Brockway discussed strategies and

methods for stand conversion from even-aged to uneven-aged

structures and forest type conversions for changing the dominant tree

species on sites.

Following the indoor session, attendees visited the CFEOR Signature

Project research plots, on THSF where Kimberly Bohn, Assistant Professor in Silviculture at the West Florida

Research and Education Center, University of Florida, David Morse, THSF Forester and Ace Haddock, THSF

Supervisor further discussed uneven-aged management and approaches for stand conversion. For more

information about the Pro-B method, contact Edward Lowenstein at loeweed@auburn.edu or Dale Brockway

at dbrockway@fs.fed.us. For more information about CFEOR workshops please visit our

CFEOR Updates 3

Recent Research Findings

Modeling spatio-temporal wildfire ignition point patterns

Hering, A. S.; C. L. Bell; M. G. Genton, 2009. Environmental and Ecological Statistics, Volume 16 (2) pages 225-250.

We analyze and model the structure of spatio-temporal wildfire ignitions in the St. Johns River Water Management

District in northeastern Florida. Previous studies, based on the K-function and an assumption of homogeneity, have

shown that wildfire events occur in clusters. We revisit this analysis based on an inhomogeneous K-function and argue

that clustering is less important than initially thought. We also use K-cross functions to study multitype point patterns,

both under homogeneity and inhomogeneity assumptions, and reach similar conclusions as above regarding the

amount of clustering. Of particular interest is our finding that prescribed burns seem not to reduce significantly the

occurrence of wildfires in the current or subsequent year over this large geographical region. Finally, we describe

various point pattern models for the location of wildfires and investigate their adequacy by means of recent residual

diagnostics.
