Why do we need to inventory forest stands?
Management, Money, Policy, and Research
What is the main difference between sampling forest stands and sampling wildlife or fisheries populations?
Fish and wildlife move, making it more difficult to sample than tree
I just bought a new 100 ft logger's tape. What do I need to do before using it?
Check units & where 0 is.
If my pace is 12.4 paces/chain, how many paces do I need to cover a distance of 5.32 chains?
65.97 paces
If my pace is 13.1 pace/chain, and if it took me 145 paces to cover a distance AB, what is that distance in chains?
11.07 chains
I measured a distance and found it to be 25.81 chains by pacing, and 26.453 chains with the use of a measuring tape. What is my error percent in pacing?
2.4%
I paced a distance and calculate it in chains. How many decimals should I present the result? Explain.
2 decimals to the nearest link because pacing is an estimation

You found later that the declination on this compass was set at 0°, instead of 5°W which was the current declination at your locality. If the reading was N3°W, what is the true bearing?N2°ESuppose you want to measure direction, what are the first few things you have to do when you pick up a new compass?Check azimuth or bearing & declinationIf you are walking in the direction of S35°W, and now you want to turn 90° left, what is the bearing of the new direction?S55°EIf you are walking in the direction of S35°W, and now you want to turn 180° left, what is the bearing of the new direction?N35°EWhat is the name of the device used to measure map area?PlanimeterWhat are the drawbacks of "metes and bounds" surveys?It is a description rather than actual measurementsWhat is the name of the survey system that replaced the metes and bounds surveys?US Public Land Survey SystemWhat are the dimensions of a tract, township, and section?24x24, 6x6, 1x1 (miles)Given that the dot grids contain 25 dots per square inch, and that the scale of the map is 4 inches to the mile, compute area in acres of a tract covering 450 dots.720 acres
