Riparian Stand Management

Pertinent Data taken
from Biometrics study 2008


compiled for Pete Cafferata by Kate Sullivan

Data from model runs from yet another biometrics
model for estimating effect of management
scenarios on wood recruitment to streams.



From Jun 2008 Draft report, Chap 4


Biometrics Inc, Seattle WA.

Scenarios shown (more were computed):

1) Report Name: ALT03

described something like bank
stability zone + management to encourage large trees in
middle then economic mgt in outer zone >100 ft.

2) No Action: self explanatory

3) Report Name: FFR Option 2>10 ft. This one is described
as current WA forest practice rules that allow no harvest in
near stream and middle zone up to 100 feet or so and
economic mgt in outer band. I call this the DFC scenario
(desired future conditions)
