Question 1
Which of the following best describes the primary distinction between municipal
arboriculture and urban forestry?
A) Municipal arboriculture focuses exclusively on tree pruning, while urban
forestry addresses all vegetation types
B) Municipal arboriculture is a specialized field dealing with trees on public land,
while urban forestry encompasses all greenspaces within a city
C) Municipal arboriculture pertains to private residential trees, while urban
forestry addresses public trees only
D) There is no meaningful distinction between the two terms
Answer: B. Municipal arboriculture is a specialized field of arboriculture and
urban forestry that deals specifically with the management of planted and
naturally occurring greenspaces on public land in communities. Urban forestry,
by contrast, encompasses all greenspaces within a city, including both public and
private lands . Arboriculture itself focuses on tree care activities applied to
individual trees and small groups of trees.
Question 2
What is the minimum passing score required for the ISA Certified Arborist
Municipal Specialist® examination?
A) 70 percent
B) 72 percent
,C) 76 percent
D) 80 percent
Answer: B. The current passing score for the ISA Certified Arborist Municipal
Specialist® examination is 72 percent . This is lower than the 76 percent passing
score required for the ISA Certified Arborist® credential. The examination
consists of 115 multiple-choice questions, and candidates have 120 minutes to
complete the test.
Question 3
Which of the following is a prerequisite for taking the ISA Certified Arborist
Municipal Specialist® examination?
A) A bachelor's degree in forestry or horticulture
B) Five years of experience in any tree care position
C) Must be an ISA Certified Arborist® in good standing
D) Completion of an accredited urban forestry internship program
Answer: C. To be eligible for the ISA Certified Arborist Municipal Specialist®
credential, candidates must be an ISA Certified Arborist® in good standing and
have a minimum of three additional years of documented and verifiable work
experience in a position managing the establishment and maintenance of urban
trees . The credential represents a specialty within the arboriculture profession.
Question 4
The Urban Forest Effects (UFORE) model is designed to quantify which of the
following?
A) The number of trees that should be planted annually in a municipality
B) The amount and value of atmospheric contaminant removal, carbon storage,
and energy conservation provided by trees
C) The economic impact of tree-related infrastructure damage
D) The optimal species diversity index for urban forests
Answer: B. The Urban Forest Effects (UFORE) model uses field data to provide
information on the amount and value of atmospheric contaminant removal,
carbon storage, and energy conservation. It uses real-time, standardized field
,data from randomly located plots and local hourly air pollution and
meteorological data to quantify urban forest structure and numerous urban
forest effects .
Question 5
Which of the following describes the "10-20-30 rule" commonly used in Urban
Forest Management Plans?
A) 10 percent of trees should be replaced every 20 years, with a canopy cover goal
of 30 percent
B) 10 percent of the canopy should be comprised of native species, 20 percent
should be mature trees, and 30 percent should be street trees
C) 10 percent of the tree population should be removed, 20 percent should be
pruned, and 30 percent should be planted each decade
D) 10 percent of the canopy should consist of young trees, 20 percent of medium-
age trees, and 30 percent of mature trees
Answer: B. The 10-20-30 rule is a common UFMP target that sets canopy
composition goals to promote diversity and resilience: 10 percent native species,
20 percent mature trees, and 30 percent street trees . This rule helps guide
species selection and age distribution to create a more sustainable and resilient
urban forest.
Question 6
Biogenic volatile organic compounds (BVOCs) produced by some trees can
contribute to the formation of which atmospheric pollutants?
A) Particulate matter and sulfur dioxide
B) Ozone and carbon monoxide
C) Nitrogen oxides and methane
D) Chlorofluorocarbons and carbon dioxide
Answer: B. Some trees produce biogenic volatile organic compounds that
contribute to the formation of ozone and carbon monoxide . While trees
generally improve air quality by absorbing and intercepting atmospheric
contaminants, the production of BVOCs represents a trade-off that municipal
arborists must understand when selecting species for urban environments.
, Question 7
For maximum energy conservation benefits in warm climates, trees should be
planted on which sides of buildings?
A) North and south sides
B) East and west sides
C) South and west sides
D) All sides equally
Answer: B. To maximize energy benefits in warm climate areas, trees should be
planted on the east and west sides of buildings . This strategic placement
provides shade during the morning and afternoon hours when solar radiation is
most intense, reducing cooling costs while avoiding excessive shading that could
increase heating costs in winter.
Question 8
The Council of Tree and Landscape Appraisers recommends which two primary
methods for valuing plants?
A) Market Value Method and Income Capitalization Method
B) Replacement Cost Method and Trunk Formula Method
C) Comparable Sales Method and Cost Approach Method
D) Depreciated Replacement Cost Method and Net Present Value Method
Answer: B. The two methods of valuing plants recommended by the Council of
Tree and Landscape Appraisers are the Replacement Cost Method and the Trunk
Formula Method . These methods provide standardized approaches for
determining the monetary value of trees, which is essential for legal
proceedings, insurance claims, and justifying urban forestry program funding.
Question 9
Which of the following is NOT considered a direct environmental benefit of trees
in urban areas?
A) Reducing stormwater runoff and erosion
B) Mitigating global warming through carbon sequestration
C) Increasing property values
D) Reducing smog production by lowering temperatures
