What are the three things that can happen when light hits something?
Ans: The light can be REFLECTED back, ABSORBED, and TRANSMITTED straight
through
Ans: in lower wavelengths (visible light), we see PIGMENTS. In near-infrared,
we see CELL STRUCTURE. in shortwave infrared, we see WATER ABSORBTION.
What is the red edge and what does its shift represent?
Ans: The reflection of red light compared to the rest of visible light in plants.
shows how healthy the foliage is?
What is NORMALIZED DIFFERENCE VEGETATION INDEX?
Ans: The readings of VISIBLE LIGHT and NEAR INFRARED which shows us
health of a plant in terms of its foliage
What is PHENOLOGY?
Ans: Observing the timing of biological events in relation to changes in
season and climate, such as when leaves fall and bloom on a tree.
What is SITE? What is SITE QUALITY?
Sunday, 02 March 2025
,Ans: The ABIOTIC environment in which a stand in growing. Variables include
soil, topography, and climate. SITE QUALITY refers to the "potential
productivity" in forestry.
What is teh "PHYSICAL FACTORS APPROACH"? What are the pros and
cons of this?
Ans: accuratre but expensive. use direct measurements of site quality, such
as nutrient content
What is the indicator species approach for determining site quality?
Ans: uses indicator species to determine site quality. quick assesment
possible in certain locations, but understory flora gets complicated as you
move south
What is the tree growth site quality approach?
Ans: Because height growth is very dependant on site quality (and not really
dependent on competition), you can guess
What is a STATISTIC?
Ans: Characteristics of the sampled subset. There will always be a degree of
uncertainty, because you didn't measure everything.
What does SAMPLING uncertainty depend on?
Ans: SAMPLING DESIGN. GOAL: Maximize precision for least cost, without
compromising accuracy.

, What are the different kinds of "plots"/SAMPLING UNITS?
Ans: Fixed area, variable radius
What are EQUAL PROBABILITY sampling units?
Ans: The plot has the same contents as the population; if you scale up what
you find in a fixed area plot, it should be similar to the whole population.
What are UNEQUAL PROBABILITY sampling units?
Ans: Sampling units which skew the sampling compared to the population.
Variable radius plots favor larger trees.
What is a SAMPLING FRAME?
Ans: List or diagram of all possible sampling units, such as a map of all
possible plot locations
What is a CENSUS?
Ans: A measuring of everything in the SAMPLING FRAME
What does increasing plot size tend to do in terms of variability? What
can you do to have this same effect without an increase in cost?
Ans: Increases variability WITHIN plots, and decreases variability BETWEEN
plots. You can also simply STRETCH the plots.
What are the methods of selection?
