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
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 [email protected] or Dale Brockway

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.
