To whom it may concern,
I write as an Irish forestry student undertaking research in the
field of optimal bucking of forest stands.
In reviewing the literature on this topic I obtained papers and
references concerning several different optimal bucking systems
(Please see extensive bibliography below).
Some were developed, initially at least, as purely instructional tools.
Others were intended for use at stump or skidsite to assit
motor-manual bucking i.e BUCK (Sessions et al, 1988) and HW-BUCK
(Pickens et al, 1993). The MARVL system(s) (Deadman, 1990;
Deadman and Goulding, 1979) and the programs
compiled by Eng et al (1986) and Sessions et al (1989b) were devised
to predict optimal product output from whole stands based upon pre-harvest
inventory and log specifications, and with volume constraints.
I would appreciate any information (literaure references) and
opinions on the current status and level of use of the above systems.
Of particular interest:
Whether or not AVIS (Geerts and Twaddle, 1984; Twaddle and Goulding, 1989)
and VISION(modified) (Lembersky and Chi, 1984) were adopted for actual use
on-site like BUCK (Sessions et al, 1988) and HW-BUCK (Pickens et
al, 1993)
If the programs of Eng et al (1986) and Sessions et al (1989b) received
practical implementation and are used in the way MARVL is.
The fate of STUMP (Brisbin et al, 1988) and TREE VALUE SYSTEM
(Briggs, 1989)
Whether additional systems exist for or other papers have been written
on approaches to optimising individual stem and stand bucking (not
listed below)
Many thanks in advance,
Yours sincerely,
