Roseburg, the mill/area its from

WWP, maybe the actual operator/mill/timber grader.

R S-Grn, no idea.

D Fir, Oregon.

Const, constuction grade
Sel Str, select grade

S-Grn - Sawn Green???

[Jedo_03]

Douglas Fir AKA Oregon Pine : Psuedosuga taxifolia
is neither a true fir
or a true pine. . .

[Toolin Around]

Roseburg - is most likely the mill in Roseburg Oregon, USA.
wwp - is the standard used to grade the timber set out by Western Wood Products Association
s-grn - over 19% moisture content at time of surfacing
D-Fir - Douglas Fir species of timber
SEL STR - Select Structural
CONST - contruction grade (not very good, warped, cracked, big knots...)

And its not suitable for posts in a wet or damp environment

The doug fir may be completely usless for structrual where damp or termites may be a problem buy it can be made to work very nicely TVM without too much effort.
cretainly worth thinking before you just hack it about.
cheers
