What are the key factors influencing soil compaction? - Soil texture, moisture content, and traffic
intensity.
How does soil compaction impact tree health? - Compacted soil restricts root growth, reduces oxygen
availability, and disrupts water infiltration.
Define cambium and its role in tree growth. - The cambium is a layer of cells in trees responsible for
secondary growth, producing new xylem and phloem.
Explain how trees resist wind loading. - Trees resist wind loading through flexibility, crown structure, and
trunk taper.
Name three characteristics used in tree identification. - Leaf shape, bark characteristics, and
reproductive structures.
What factors should be considered when selecting trees for urban environments? - Climate suitability,
soil conditions, and space availability.
What are the best practices for planting a tree? - Dig a wide planting hole, place the tree at the correct
depth, and water thoroughly.
How can mulching benefit newly planted trees? - Mulching conserves soil moisture, suppresses weeds,
and moderates soil temperature.
Define three types of pruning cuts. - Heading cut, thinning cut, and reduction cut.
Why is proper pruning important for tree health? - Proper pruning promotes structural integrity,
reduces risk, and enhances aesthetic appeal.
What are common signs of tree stress? - Leaf discoloration, premature leaf drop, and dieback.
, How can you differentiate between abiotic and biotic tree disorders? - Abiotic disorders result from non-
living factors, while biotic disorders are caused by living organisms.
Name two methods for controlling insect pests on trees. - Biological control and integrated pest
management (IPM).
How can you promote tree health through fertilization? - Conduct a soil test and apply appropriate
nutrients based on the results.
What factors contribute to tree risk? - Decay, structural defects, and environmental conditions.
How can you assess tree risk? - Conduct a visual inspection, consider tree species and history, and use
diagnostic tools if necessary.
Explain the concept of soil aeration and its importance for tree roots. - Soil aeration refers to the
presence of air in the soil. It is crucial for tree roots as it ensures the availability of oxygen, necessary for
root respiration.
Describe the benefits of incorporating organic matter into soil. - Organic matter improves soil structure,
water retention, and nutrient availability. It also encourages beneficial microbial activity.
Discuss the process of photosynthesis and its significance for trees. - Photosynthesis is the process by
which trees convert sunlight into energy, producing oxygen as a byproduct. It is essential for tree growth
and carbon dioxide absorption.
What is transpiration, and how does it contribute to the movement of water in trees? - Transpiration is
the process of water movement through a plant and its evaporation from aerial parts, such as leaves. It
creates a negative pressure that pulls water upward in the xylem.
Name three tree species that are commonly used as street trees in urban environments and explain why
they are suitable. - Examples could include Ginkgo biloba (tolerant to pollution), Acer platanoides
(urban-tolerant), and Quercus robur (hardy and adaptable).
