Name 3 basic navigation measurements and a tool to measure each -
(answers)Direction: compass
Distance: pace, tape, ruler on a map
Elevation (or change in it): altimeter (clinometer)
What bearing corresponds to an azimuth of 139 degrees?
221 degrees
N 41degrees E
S 41 degrees W
S 41 degrees E - (answers)S 41 degrees E
You run a traverse on some forest property using a Silva or Suunto hand compass
and cloth tape. How close can you be expected to read the azimuth scale on your
compass? - (answers)the smallest division of most hand compasses is 2 degrees,
so the best one can expect someone to read bearings/azimuths is to the nearest 2
degrees, maybe 1.
what are the 3 R's needed for setting up a research design for a manipulative
experiment to ensure valid statistical analyses? - (answers)randomization
representation
, 2|Page
replication
why does vegetation appear very bright in infrared photographs or images? -
(answers)healthy green vegetation is a very strong reflector of infrared radiation.
in infrared photography or imagery, sometimes called false color imagery, the
infrared energy is represented by the red color. the intensity of the red
corresponds to the amount of the infrared energy being reflected by the target.
thus, the higher near-infrared reflectance, the brighter the red color in imagery.
True or False? A two-sided (alternative) hypothesis describes departure from Ho
in one direction (e.g., H_A:q>q_o). - (answers)False, i.e., a 2-sided (alternative)
hypothesis describes departure from H_o in two directions (e.g., H_A: q doesn't
equal q_o)
Define basal area and tell why it's important - (answers)BA = cross sectional area
of the tree at breast height iin ft^2.
BA = pi * (D / (2 x 12))^2 = 0.005454 * D^2 (converts DBH (or D) in inches to BA in
ft^2)
Stand basal area = sum of individual tree basal areas in a stand
It's important b/c BA is directly related to crown surface area, BA and HT can give
an indication of wood volume, BA is one parameter used to assess a forest.
You're 200 ft away from a tree on flat ground to measure its height. The
clinometer reading to the top is 50% and to base it's 10%. How tall is the tree? -
(answers)Dist * ((Top% - Base%)/100)
H = 200 * (((50-(-10))/100) = 120 feet tall
