1) Describe the effect of increased carbon dioxide on forest growth. - (answer)Increased CO2 can
improve photosynthesis efficiency and increase forest growth. However heat associated with increased
C02 may lead to more extreme weather events causing more high intensity fires.
2) List three (3) conditions that demonstrate forest sustainability (note this is not simply sustained yield).
- (answer)When management decision take into account the environment, economy and society
3) What is the primary cause of long term natural (not anthropogenic) global climate change? -
(answer)The Milankovitch cycle is the natural wobble in the earth's tilt and rotation that change the
relative position and alignment between the earth and the sun leading to changes in climate. This
changes the
4) What is Tree Improvement? - (answer)Improving the specific characteristics of a tree through
controlled breeding or cultural practices
5) What is a Provenance Trial? - (answer)A planting in which population samples from stands of known
geographic origins are grown together in one or more location.
6) What is a Genotype? - (answer)An individual's hereditary (genetic) constitution.
7) List three (3) objectives of forest fuel treatments? - (answer)Reduce fuel loads to prevent stand
destroying fires
Decrease competition among remaining trees
Generate biomass
8) List three (3) effects of sawtimber harvesting on forest carbon sequestration? - (answer)Can begin the
slow release of standing carbon in living trees that are converted to lumber
Can allow for vigorous new growth if harvesting overstocked trees

9) List three (3) results of intense forest wildfire on carbon stocks? - (answer)Massive release of CO2 into
the atmosphere from sequestered carbon.
Can slow site from being capable of sequestering carbon due to hydrophobic soils
Allow for increased carbon sequestration of new stand that has not yet reached maximum growth rates.
10) What is biological diversity? - (answer)The variety and abundance of life forms, processes, function
and structure of plants, animals and other living organisms including the relative complexity of species,
communities, gene pools and ecosystems and spatial scales that range from local through regional to
global. A measure of diversity either among species, between species or of ecosystems
11) List three (3) main sources of genetic diversity in forests? - (answer)Natural selection, mutation,
genetic drift
12) What determines the extent of genetic impacts of forest management? - (answer)The phenotypic
variation of a tree species. Some trees have very similar growth characteristics across a wide variety of
genotypes and instead growth rates are more attributed to the environment. Some trees species have
widely varying growth characteristics based on genotype.
13) According to the FPRs and PRC, what is watercourse? - (answer)Any well-defined channel with
distinguishable bed and bank showing evidence of having contained flowing water indicated by deposit
of rock, sand, gravel, or soil, including but not limited to, Streams as defined in PRC 4528(f).
Watercourse also includes manmade Watercourses.
14) List three (3) potential impacts of water drafting on aquatic species. - (answer)Mechanical take of
aquatic organisms from improper pump equipment
Increased sedimentation of the water
Loss of habitat if overdrafting
Change in water temperature

Verified Test |100% Verified solutions |2026 Latest!!
15) List three (3) common mitigation measures to reduce sediment leaving water drafting site
approaches and entering watercourses? - (answer)Rock armor the road surface
Use erosion control measures like hay bales/ wattles between drafting truck and draft site
Place water drafting sites where there won't be a steep climb to draft site
16) What is the Fish and Game Code definition of "Fish"? - (answer)Any wild fish, mollusk, crustacean,
amphibian, invertebrate or part, ovum spawn of those animals
17) List three (3) common mitigation measures (other than paving) that are commonly used to reduce
the potential adverse effects of road dust. - (answer)Water the road surfaces
Chemical application to increase soil cohesion of road surface
Decrease road travel speed
18) What are three (3) uses of site indexes in forestry? - (answer)Planning for maximum sustained yield,
deciding species composition when planting.
Predicting growth rates
Comparing
19) Many forest management decision models (usually computer software aided) are commonly utilized
to support forest management decisions. Briefly describe the most common method: Linear
programming. - (answer)
20) Briefly describe the basic decision-making process used in forest management planning. -
(answer)The practical application of biological, physical, quantitative, managerial, economic, social and
policy principles to the regeneration, management, utilization and conservation of forests to meet
specified goals and objectives while maintaining the productivity of the forest. Determine objectives,
research alternatives, compare results, choose the best alternative, implement alternative, track
outcome, use result to inform the next set of decision

21) What is forest succession? - (answer)The gradual cyclical replacement of one dominating plant type
for another starting from bare ground and progressing to a climax forest and the restarting of the cycle
based on a natural or anthropogenic disturbance
22) How is biological diversity described or measured? - (answer)Measured as the range in variation
among species, between species and of ecosystems
23) List two (2) anthropogenic disturbance-recovery regimes that have affected western forests in the
USA. - (answer)Fire suppression
Change in species composition with planting and selective harvesting
24) List four (4) general abiotic characteristics used to describe a forest stand. - (answer)Slope, aspect,
climate, elevation, soil type
25) Why is it not sufficient to manage for biological diversity at the stand level alone? - (answer)Because
the cumulative impacts of management decisions across multiple stands can have an effect that is
greater than the sum of the parts and because the habitat encompassed by a stand is not sufficient in
itself to provide the needs for wild plant and animal populations.
26) Explain what a significant existing or potentially significant erosion site is. - (answer)Significant
means soil erosion that is currently, or, as determined based upon visible physical conditions, may be in
the future, discharged to Watercourses or lakes in quantities that violate Water Quality Requirements or
result in significant individual or cumulative adverse Impacts to the beneficial uses of water. One
indicator of a Significant Sediment Discharge is a visible increase in turbidity CALIFORNIA FOREST
PRACTICE RULES 21 to receiving Class I, II, III, or IV waters
27) Explain what a Significant Sediment Discharge is. - (answer)A significant amount of sediment that
has a negative effect on an aquatic ecosystem
28) What are silvics? - (answer)The study of the life history and general characteristics of forest trees
and stands with particular reference to environmental factors as basis for the practice of silviculture.
