CATS Arborist Albuquerque Tree Health & Disease Management 5

Question 1

Which tree species native to the Albuquerque region is particularly resistant to drought and heat stress compared to non-native ornamentals?

Accepted Answer

One-seed juniper (Juniperus monosperma)

Answer

One-seed juniper is native to the Albuquerque region and is highly adapted to the arid climate, alkaline soils, and temperature extremes that cause stress in non-native ornamental species.

Question 2

What is the recommended approach when a significant percentage of a tree's root zone is paved over in an urban setting?

Accepted Answer

Use vertical mulching, aeration, or structural soil systems to improve gas exchange and water infiltration

Answer

Vertical mulching, air spading, and structural soil systems create pathways for oxygen and water to reach roots under pavement, improving conditions without removing the hardscape.

Question 3

How does Albuquerque's low humidity and high UV radiation affect the incidence of foliar fungal diseases compared to wetter climates?

Accepted Answer

They generally reduce foliar fungal diseases because spore germination requires moisture

Answer

Most foliar fungal pathogens require moisture on leaf surfaces to germinate and infect; Albuquerque's arid, low-humidity climate reduces foliar fungal disease pressure compared to humid regions.

Question 4

Which symptom would most strongly suggest Armillaria root rot rather than drought stress in a declining landscape tree?

Accepted Answer

White mycelial fans under the bark at the root collar

Answer

Armillaria species produce characteristic white mycelial fans (sheets of fungal tissue) between the bark and wood at the root collar and root surface, which is a definitive diagnostic sign.

Question 5

When using the ISA Tree Risk Assessment Qualification (TRAQ) framework, what three factors combine to determine overall tree risk?

Accepted Answer

Likelihood of failure, likelihood of impact, and consequences of failure

Answer

The TRAQ framework calculates overall risk by combining the likelihood of part or whole tree failure, the likelihood that a falling part would strike a target, and the consequences (severity) of that impact.
