B.S.F. or B.Sc.F. Bachelor of Science in Forestry Forest Mensuration and Timber Inventory 2

Question 1

The USDA Forest Inventory and Analysis (FIA) program provides:

Accepted Answer

A national database of forest area, volume, growth, and mortality updated on continuous cycles

Answer

FIA is the nation's continuous forest census, remeasuring permanent plots across all ownerships to track changes in forest resources over time.

Question 2

Increment borers are used in mensuration to:

Accepted Answer

Extract a core from a living tree to determine age and radial growth rates

Answer

An increment borer extracts a pencil-thin wood core from a standing tree, allowing foresters to count annual rings and measure past radial growth.

Question 3

What is 'stand volume' as used in timber inventory?

Accepted Answer

The total wood volume of all trees in a defined area, usually expressed per acre

Answer

Stand volume aggregates the estimated wood volume of all individual trees within a given area, typically reported in board feet or cubic feet per acre.

Question 4

The 'form factor' of a tree in mensuration corrects for the fact that:

Accepted Answer

Tree stems taper and are not perfect cylinders, so actual volume is less than a cylinder of the same DBH and height

Answer

The form factor (or form quotient) adjusts the theoretical cylinder volume (based on DBH and height) to the actual stem volume by accounting for taper.

Question 5

In a fixed-radius plot design, what information is primarily collected from each plot?

Accepted Answer

Species, DBH, and height of all trees within the plot boundary

Answer

Fixed-radius plots record species identity, DBH, and often height for all qualifying trees within a set distance from the plot center, enabling volume and density calculations.
