A. Even-aged
management
1.
tends
to favor edge species initially
Clearcuts and seed-tree systems remove most of the food
and cover for forest species, but create opportunities for openland species.
Shelterwood cuts create edge and diverse structure
in the forest during the initial cuts, but result in more uniform structure
with less edge after the final harvest.
2.
may
favor edge or interior species as forest matures
B...
Uneven-aged management
1.
may
favor interior species
2.
results
in fewer changes in the understory
Single tree selection results in very little change
in the structure of the stand relative to wildlife food and cover.
Group selection created more openings in the canopy and more shrub and herbaceous vegetation at ground level.
C. Of what
value is dead wood?
1. Snag - any dying or dead tree that is at least 4" dbh and
20' tall
2. Stages of snag succession
Stage 1 –
Live tree beginning to deteriorate
Stage 2 –
Only a few live branches, tree mostly dead
Stage 3 –
Tree totally dead, but branches and bark intact
Stage 4 –
Bark begins to loosen
Stage 5 –
Bark stripped clean and limbs fallen
Stage 6 –
Top breaks off and snag is soft (bole is rotten)
Stage 7 –
Rotten stump standing
a.
Provide
different structure
b.
Provides for a variety of
wildlife food and cover
3.Goal:
minimum of 2 snags/ac
4. Downed wood provides the same benefits as snags
but at ground level
Proper forest management and management for wildlife
can be compatible or incompatible, depending on the techniques being used and
depending on the goals for the forested land.
