Harvesting Final

QuestionAnswer
3 Reasons we use BMPs Improve aesthetics, protect water quality, wildlife
What is Deflection and how is it calculated? Sag/Span; Distance between tail hole and yarder = span Sag=Height from line should be to where it's at when loaded
How to increase deflection? Does more sag increase or decrease payload? more sag = payload increase Increase Defelction = add intermediate supports, make towers taller, slack the main line
Name the dirty dozen Poor Road Location, Not enough water turnouts, Grade too steep, Using SMZ soil to cover a culvert, improper crown, blocked culverts, failure to stabilize soils, logging debris blocking ditches, narrow objectives, not enough culvert soil settling time
Why aren't forestry roads benign decrease in water quality, increase land slide frequency, habitat fragmentation
5 processes of harvesting felling, primary transport, processing, loading, secondary transport
5 characteristics that define road standards grade, curves, subgrade width, ditches, cut/fill slope ratios
3 factors of a sustainable forest economically feasible, socially desireable, ecologically viable
3 forms of primary transport skidding, yarding, forwarding
3 felling methods herringbone, contour, perpendicular
Advantage of Mechanical Felling higher felling production, extraction costs reduced, sorting is possible, lower stump heights
Disadvantages of Mechanical Felling Limited range of stem sizes, Limited by slope, higher cost, potential stem damage
Maximum skid distance and favorable slope 600 feet and less than 30-35% slope
Chain Chokers Chokers could freeze, difficult to get under logs, less hazardous to handle than cable
3 harvesting Systems whole tree, tree length, cut-to-length
3 Yarding Systems Highlead, aerial, skyline
What 5 things do written plans do? 1. Help remember to consider all factors 2. Document our efforts to properly plan 3.Can minimize miscommunication 4.Information is easier to share with others 5. Need to be simpled, detailed, effective
6 Reason to have harvest plans Financial, Legal, Silvicultural, Safety, Aesthetic, Personal
12 Steps to to an Operational Harvest Plan Identify and mark SMZs, Locate and Flag Landings, Locate and mark logging road stream crossings, specify close down requirements, determine the schedule of operation and harvest pattern, specify stream crossing structures
Issues to consider when thinning stand conditions before thinning, stand conditions after thinning, thinning method, tree selection, follow-up treatments, damage to stand, BMPs
3 Main Effects of Soil Disturbance Topsoil Displacement, Erosion, Compaction
3 Ways to Assess Soil Disturbance Visual, Soil Strenght Measurements, Bulk Density
KSAR Knowledge, Skill, Ability, Risk
Forestry Impacts on Water Lower evapotranspiration, higher evaporation from soil, higher air temperatures, higher water temperatures
Opportunity Tests Switching, Attitudes, Labels, Tax Reporting, Business Structure
Harvesting Analysis Methods Empirical, Loggers Common, Regional Average
Why Analyze Forest Operations Build general knowledge of machines and systems, new machine opportunities, understand new terrain and conditional requirements, set standards for incentive programs, equipment replacement decisions,
4 Major Time Components Productive Time, Idle Time, Service Time, Down Time
3 Types of Time Studies Gross, Work Sampling, Elemental
Indirect Logging Costs Moving Expenses, Permits and Regulations, Roads and Landings
6 Cost Categories Consumable Supplies (Variable), Labor (Variable & Fixed), Equipment (Fixed), Insurance (Variable & Fixed), Contract Hauling (Variable), Administration and Overhead (Fixed)

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.
