1 chain correct answers 66 ft= 100 links
1 link correct answers 0.66ft= 7.9 inches
1ft correct answers 12 inches
1 acre correct answers 43560 sq. ft= 10ch^2
Why must you always use horizontal distances? correct answers Its the true distance!
Break chains? correct answers breaks slope distance into smaller segments..bc you want
horizontal distance
How many decimals do you need when measuring in chains? correct answers 3 decimals, to be
as accurate to the nearest 1/10th
how many decimals for paces? correct answers 2 decimals to be accurate to the nearest link
Why do foresters use chains as measuring? correct answers measures longer distance than ft.....
easier to convert from ch^2 to acre
Why don't backsight or foresight match up sometimes? correct answers Operator error or too
close to large source of metal....2 degree difference is ok, more than that isn't good
declination correct answers deviation from TRUE north
1st things to do with new compass? correct answers 1) find zero
2) 10 or 20 tick marks?
Where does azimuth start? correct answers North
total interior angles= correct answers (n-2)180
What replaced the metes and bounds survey? correct answers US Public Land Survey
Quadrangle correct answers 24x24
Township correct answers 6x6
section correct answers 1x1
GIS correct answers Geographical information system
GPS correct answers Global positioning system
, DBH correct answers diameter at breast height...diameter outside bark @ 4.5'
Why breast height? correct answers standard height and is often free of butt swells
diameter classes correct answers 1'' and 2'' classes
1'' class correct answers ODD NUMBERSSSS ONLLLLYYYYY
ex: 17.51-18.5
2'' class correct answers whataaeevvvaaaaaa numbers ya don't know ¯\_(ツ)_/¯
17.01-19.0
dendrometers correct answers measure DIAMETER
hypsometer correct answers measures HEIGHT
D-tape correct answers usually overestimates (exception perfect circle)
MEASURE CIRCUMFERENCE NOT DIAMETER... (dendrometer)
Calipers correct answers always decimal....MORE ACCURATE...2 perpendicular measurements
(dendrometer)
Biltmore stick correct answers dendrometer... no difference between this and caliper..2
perpendicular measurements..standing 25'' from tree (avg arm length)...graduation formula
needed for this?
graduation formula correct answers G= D/(sq root of (1+D/A))
A= arm length
D= diameter
Basal area correct answers cross sectional area @ breast height....AREA OF
STUMP....INDICATES HOW CLOSE OR SPARSE TREES ARE
dib (diameter inside bark) correct answers dib: dob-(double bark thickness)
if tree is at a slope where do you measure it at? correct answers the uphill slope
Leaning tree? correct answers right angles to the lean of the tree
FORKSS IN TREES correct answers 1) fork is greater than 4.5'= MEASURE AS NORMAL
2) fork is less than 4.5'= MEASURE @ 3.5' FROM FORK AS TWO TREES
BUTT SWELLS correct answers 1) BELOW 3FT--- MEASURE DBH AT 4.5'
2) ABOVE 3FT--- MEASURE 1.5' ABOVE BUTT SWELL
