conflict resolution
a. change supply
b. change demand ex. pricing
c. separation in time
ex. hunting one season, skiing next season
d. separation in space
ex. skiing on one side of hill, snowmobile on other
e. equal power
3 types of compatibility between users and uses
a. complementary uses (they improve eachother)
ex. swimming and clean water
b. compatable uses (two coexist with little impact on eachother)
ex. hiking and wilderness
c. conflicting uses (cant be together b/c adverse effects)
ex. snowmobiles on horse riding trails
how does one discover what society wants/needs
a. surveys/polls
b. public meetings
c. historical use
d. govt representatives

* we also need to know the limitations of the resource (what will the land support)
4 types of logging systems
a. short wood (15%)
b. tree length (78%)
c. full tree (5%)
d. remote chipping (2%)
how is it possible to manage uses simultaneoulsy
=first understand potential outputs and know what society wants
length of plans
long- 20 year plan
medium- 5 year plan
short- annually
problem with multiple use management
=not all the uses can be managed simultaneously but had to work it with minimal conflicts
what factors does one look at when cutting a forest
-water crossings, work camps, rail needs, mapping, area to be cut, road lay out, sequence to be cut
what does cutting affect
a. tree re-establishment
b. wildlife
c. soil
d. water
e. recreation
f. aesthetics
g. grazing
reasons for cutting a tree
a. merchantable volume
b. sanitation ex. disease
c. salvage ex. burned areas
d. rights of way
ex. roads, powerlines,seismic lines
e. developments
f. fuel breaks
g. density control (thinning)
fuel breaks
=break in fuel continuity so it won't spread
ex. road, transmission line
the type of logging system used depends on
a. age/size of timber
b. product
c. harvesting limitations
(2 conditions)
d. accessibility
e. value
f. environmental restrictions
what happens when MAI is the highest?
-it determines the rotation age
multiple use mangagement
uses:
a. timber
b. water
c. recreation
d. range
e. wildlife
2 conditions of harvesting limitations
a. site conditions (need 30% slope, wet terrain, leave tree specification)
b. equipment restrictions
what must foresters do to increase the cut
a. improve growing stock
b. reduce losses (ex. fire suppression)
c. use more efficiently/completely
d. pay fair market values (buy locally)
The wood volume harvest is influenced by
a. growth potential of the site (site index)
b. existing growing stock
c. evenness of flow demanded
d. other constraints
list some other constraints that volume harvest is influenced by
a. high recreation values
b. clearcut size restrictions
c. watershed valves or problems
d. wildlife constraints
e. allocation limitations
