Announcing the 2019
Variable Probability Sampling Workshop
March 25 - 29, 2019
Oregon State University
The Variable Probability Sampling course is offered as a service to
foresters. Two popular methods of timber cruising will be covered in
detail: variable-plot sampling and 3-P sampling (Probability,
Proportional to Prediction). The course is suitable for relative
beginners as well as those with experience who like to brush up on the
principles and up-to-date computation techniques using hand calculators
and microcomputers. Field exercises using both techniques are an
important part of the course.
Participants are invited to submit problems they have encountered in
either field application or office computation in variable-plot sampling
for a special session during the first part of the program. All such
questions may be submitted in advance to the short course director, Dr.
James Kiser, before March 1, 2019.

2018 Variable Probability Shortcourse
This year was the first without John Bell running the short
course at OSU. John did, however, come to say hello at the
beginning and end of the course.
Here are the winners of the "best crew" for the Variable Plot
and 3P field exercises. (While some thought that they were just
lucky, at least one crew differed in opinion) At any rate, they
were a handsome bunch.
Congratulations to the winners, and we hope all of you had an
interesting time in Corvallis. We thank Jeff Penman for the
photos and his help at the course.

JOHN BELL RETIRES FROM THE OSU SHORT COURSE
At age 93, John Bell has decided that it is time to turn
over the short course at OSU to some younger instructors.
This year was the 60th anniversary of the short course.
People born that year are getting ready to retire.
When John and Lu Alexander started the course in 1957,
they could hardly have imagined how long it would last.
Since they doubled sessions in some years, there were 67
courses at OSU, and Kim Iles and John also put on more than
20 at various places around the world, totaling more than
2,000 timber cruisers attending.
There was a great crowd at the short course in this final
year. Jim Kiser will be taking over the program chairmanship
at OSU, and is well qualified to do it. He has lots of
experience in practical work in forest inventory, and is a
great teacher. The conference office at OSU has been
wonderful to work with, and will continue to do the
paperwork and site operations – probably at the OSU LaSells
Stewart Center while the forestry building is under
We hope that the course will continue to offer the same
practical advice to future timber cruisers. If you want to
email John, you can do so at
firstname.lastname@example.org. If you have any comments about
what should be changed or retained in the short course, we
would be happy to hear such comments. We will have a lot to
live up to.

Jim Kiser (Instructor of Forest Engineering,
Resources, and Management at Oregon State University) has just
published a handy forestry reference book. The book is
distributed by John Bell and Associates. From the preface:
"the text is meant to serve as a reference
for practicing foresters and other natural resource
professionals who work with field measurements as a part of
their job requirements. Although primarily focused on timber
and timber stand, the book also serves for typical
engineering of forest forad layout with an added section on
curve layout formulas and tables. The intent of this book
was not to provide an inclusive set of forester's tables,
but to pull together the more common tables necessary to the
day to day activities..."

Kim Iles has published his third book, “The
Retread, The Reject and the Tower Statistician”. 417
pages, bonded leather cover, $45 plus shipping. The style is
very similar to his second book. The same “OH” character from
the second book and the chapter six memos from his first book
(Sampler of Inventory Topics) is continued. It has 61 short (4-5
pages) chapters, mostly about solutions to real problems with
some practical psychology and statistical theory woven into
them, with suggestions about professional development.
If you are interested, you can check out the details at his
website : http://www.island.net/~kiles/
In regard to the Sampler of Inventory Topics
many of you have received at the OSU short course:
Any errors that have been noted in the first two editions
have all been updated and are on Kim’s website. When the Relascope spreadsheet
was first done (with the first
edition) there was a small error with some combinations of
bars for the very first books sold. Kim tried to trace down
all the owners who had that on their book CD, but if you own
the first printing (grey color) download the one that has
been here on the John Bell website for many years, and
replace the one you have - just in case.
