CALIFORNIA RPF UPDATED PRACTICE EXAM QUESTIONS
AND SOLUTIONS RATED A+
✔✔Currently, what is the status of the California's FPRs as BMPs under section 208 of
the Clean Water Act? - ✔✔California's FPRs are certified by the State Water Resources
Control Board as BMPs under Section 208
✔✔Briefly describe the distinctions between effectiveness monitoring and
implementation monitoring. - ✔✔Implementation monitoring is whether a project was
installed properly (according to specifications), while effectiveness monitoring is whether
the project achieves its stated objectives. Example: implementation monitoring would be
checking whether a culvert was installed properly, effectiveness monitoring would be
monitoring the culvert's effect on fish passage.
✔✔The Golden Spotted Oak Borer (Agrilus auroguttatus), an invasive wood-boring
beetle recently located in California, is responsible for the mortality of over 80,000 trees
in southwestern California. Name two of the three species that are currently
experiencing high rates of mortality in California from GSOB infestation. - ✔✔Coast live
oak (Quercus agrifolia), canyon live oak (Quercus chrysolepis), and California black oak
(Quercus kelloggi).
✔✔What type of tax is levied per unit of value harvested to enable the property owner to
postpone the taxes normally due until such time as income is received from the
property? - ✔✔Yield tax
✔✔A written analysis of preharvest and postharvest timber stand conditions and a
description of the silvicultural practices and systems to be used in lieu of the standard
methods is called - ✔✔Alternative prescription
✔✔As the RPF retained by the plan submitter to provide professional advice throughout
timber operations, you discover a previously unreported potentially significant historic
archaeological site. According to the FPRs, list your responsibilities in this matter. -
✔✔Halt operations, provide a no ops buffer, contact CALFIRE, identify the site, develop
mitigations, and amend the submitted plan.
✔✔Both Oregon and California predominantly use the Scribner Dec. C log rule. Briefly
describe the main difference in how the rule is applied in each state. - ✔✔????
✔✔The total assimilation of energy and nutrients by an organism or plant community
per unit of time is called - ✔✔Gross Primary Production
(vs. NPP, which is GPP minus biomass used in respiration)
, ✔✔What is the coefficient of variation used to measure in mensurational sampling? -
✔✔The coefficient of variation measures dispersion around a mean - it is used to
describe the amount of variation among different plots.
✔✔Which of the following tree species are NOT susceptible to white pine blister rust: -
✔✔Yes susceptible
Pinus monitcola = western white pine (5 needle)
Pinus lambertiana = sugar pine (5 needle)
Not susceptible
Pinus ponderosae = ponderosa pine (3 needle)
Pinus sabiniana = ghost pine (3 needle)
Pinus attenuata = knobcone pine (3 needle)
Pinus contorta = lodgepole pine (2 needle)
✔✔What is the term for a timber sale in which the buyer and seller agree on a total price
for marked standing trees or for trees within a defined area before the wood is removed
- note the timber is usually paid for before harvest begins? - ✔✔Lump sum sale
✔✔Dying Trees, as defined for use in the FPRs, means trees which exhibit one or more
of certain conditions. List three of the accepted conditions that would define a dying
tree. - ✔✔1. 50% + of foliage-bearing crown is dead or fading in color from green to
yellow or brown
2. Successful bark beetle attacks (dead cambium, brood development around the bole)
3. 75% + of circumference of lower bole girdled by wildlife
4. Trees designated by an RPF as likely to die within one year
✔✔What is the radius of a 1/3 acre inventory plot? Round to the nearest tenth. -
✔✔Area = Πr^2
R = square root of Area/Π
43560/3 = 14,520
√14520/3.14 = xx
✔✔Define the term marginal revenue. - ✔✔This is the additional amount that you earn
with each additional unit sale.
✔✔The genus Accipiter is a group of birds of prey in the family Accipitridae. These birds
are slender with broad rounded wings and a long tail that helps them maneuver in flight.
They are commonly found in forested, wooded, or shrubby areas. Name a sensitive
species of Accipiter that is mentioned in the FPRs. - ✔✔Hawks - one is northern
goshawk
✔✔Today, forest managers generally recognize that large woody debris is important in
influencing the biology and habitat values of streams in temperate ecosystems. List four
