FW 404 Exam Review 9/18
Read white oak/red oak article
You should know:
Three ways of management
Crop tree management
Describe the pre colonial south as was written by Dixon and the other assigned reading and World of Wounds
grand savannah
What commercial thinning is, what specific parameters might be placed in the commercial context of specific wildlife species (ex northern bobwhite) and how it may interact with prescribed fire
Three to four approaches to increase biodiversity species richness in managed loblolly pine plantations
Andro et al reading on Moodle
Longer rotations, but not realistic
Plant at lower stocking densities with higher spacing
standard: 10×10
leave snags and downed wood if possible
thin early and often (pre commercial thinning)
burning
herbicides instead of fire
diversify stand ages across the landscape to diversity age class
riparian buffers, streamside management areas
Gap-phased disturbances
trees fall next to teach other to increase gap
management that mimics disturbance: group selection (not single tree, which promotes vertical structure in the stand but not horizontal structure since it doesn’t provide enough change)
Group selection increases both vertical AND horizontal structure
affects some animals since some require larger canopy reduction
Plant succession
what kinds of plants respond early to increased light?
shade intolerance, intermediate shade tolerant, shade tolerance (focus on shade tolerance: uneven-aged systems)
Bird species richness and foliage height diversity
Reasons you might observe more animals along edge habitat, more abundance/richness
Definition and distinction between seed tree and shelterwood
What determines the spacing of seed trees?
Value of residual downed woody material following a clearcut harvest
You can do forest stand improvement as much as you want, but would want to limit it because of money and economic return
Fertilizing an oak tree increases acorn
How does prescribed fire affect forb, woody competition—why does it promote more forbs?
Distinction between source patch and sink patch
Difference between ideal free dist and ideal spotic distribution
Difference between even and uneven aged stand
what are the characteristics? which one has uniform appearance—even aged. Provides more habitat for shrubland wildlife—uneven aged (because of small patches on the ground… 3-5 years after clearcut harvest. Fewer songbirds and salamanders. More browse for deer. More fruit for wildlife.)
Challenges to implementing uneven aged silvicultural system
Two components of a diversity index
Preservation vs conservation
Ultimate vs proximate factor
Select vs prefer
Species richness vs species evenness
Woodland vs forest, savannah vs prairie
woodland = 30-80% canopy cover, herbaceous (Schenck)
Clearcut vs land clearing
Edge vs ecotone
if edge has narrow ecotone, is it a soft or hard edge? Hard
Increase edge by increasing stands into smaller units or make them irregularly shaped
Inherent vs induced edge
Timber harvest in landscape makes an induced edge, where inherent edge is where forest meets lake or parking lot
Size classes
Specialist vs generalists
Pathway of energy from sun to fitness of animals
4 orders of habitat selection and define them
Distinction between territory and home ranges
territory: defend breeding spaces like nests and dens and limited food resources
Recognize Leopold’s logistic growth curve, what it looks like, responding to carrying capacity
What is single tree selection used for
Hardwood midstory removal via herbicides via helicopters
does this increase habitat for nesting songbirds? NO!
does it increase nutrition of white tailed deer browse? NO!
does it increase amount of browse? YES!
plant nutrition is the same for the same plant, not dependent on soil type, only quantity of that plant
Differences for wildlife between clearcut timber harvest and clearcut that retains hardwood understory
Herbicides, tank mixes, dist between broadcast/spot/tank application
concerns that wildlife biologists have in industrial pine plantations
Clearcut is not used in urban development, it is deforestation
What is site index?
Can group selection harvests provide habitat for shrubland wildlife?
yes but must be large, at least 1/4-1/2 acre
larger openings
patch clearcuts
intent to create even aged patch regeneration, but very small clearcut. How small? in farm bill (less than 5 acres)
Which regeneration methods are even aged or uneven aged
Site preparation, what is it, diff between chemical and mechanical, effects on wildlife (esp mechanical), how long do effects last
Decimating and welfare factor examples
Several reasons that density and abundance may not be a good indicator of habitat quality
Ideal despotic distribution
Examples of shade intolerant trees, shade tolerant trees from the slides
Definition of basal area
Understand how native americans influenced landscape prior to 1500 and beyond
examples of how animals respond to group selection harvest openings
definition of seasonality and buffer foods
pre commercial vs commercial thinning, intent behind this, financial ramifications and when it should occur
selective harvest is often used with the intent to hygrade
intent behind residual overstory trees in shelterwood harvests
to protect regeneration from too much light
shelterwood: shelter from light and extreme conditions
Seed tree intention → to seed
Can you protect trees from clearcut harvest, reserve, keep snags
is wildfire a threat to wildlife habitat in the south? no
is clearcut a threat to habitat? no
