The importance of maintaining high species diversity

What potential ecological risk is associated with breeding American elms with Asian elm species?

The hybrid trees might become invasive and disrupt ecosystems

What does sustainable forest management aim to achieve?

Balancing environmental, social, and economic needs

Which statement best describes the genetic diversity of American chestnut trees before the blight?

They had low genetic diversity, making them vulnerable to the blight

What is clearcutting in forestry?

Removing all trees from an area at once

1. What is the primary role of forests in the Earth's ecosystem?

Supporting biodiversity and regulating climate

Which of these is a key theme of sustainable forest management?

Maintaining biological diversity

How did the evolution of Dutch elm disease complicate efforts to breed resistant American elms?

It created multiple strains, making resistance to all strains difficult

When we calculated with a ruler the height of our trees, why did it not take the last 15-20 feet?

The top few feet are not used for loggers

What challenge did the hypovirus treatment face in the Wisconsin chestnut stand?

The hypovirus didn't spread effectively to other trees

How did the introduction of chestnut blight affect the ecosystem of Eastern American forests?

It disrupted the food web and altered forest composition

How do forests contribute to water quality?

They filter pollutants and regulate water flow

The effectiveness of introducing non-native species
The benefit of clear-cutting to prevent disease spread
The importance of maintaining high species diversity
8
What potential ecological risk is associated with breeding American elms with Asian elm species?
The hybrid trees might be sterile and unable to reproduce
The hybrid trees might become invasive and disrupt ecosystems
The hybrid trees might be more susceptible to disease
The hybrid trees might grow too slowly to be viable
9

Eliminating all human activity in forests
ncreasing timber production only
Balancing environmental, social, and economic needs

They had low genetic diversity, making them vulnerable to the blight
genetic diversity was irrelevant to their susceptibility to the blight
They had high genetic diversity, making them vulnerable to the blight
They had the same genetic diversity as Asian chestnut species
11
What is clearcutting in forestry?
Planting new trees in bare areas
Selective harvesting of mature trees
Removing all trees from an area at once
Thinning out underbrush
12
Which forest management technique involves carefully selecting which trees to cut?

Providing lumber
Supporting biodiversity and regulating climate
14
Which of these is a key theme of sustainable forest management?
Encouraging urban sprawl
Promoting single-species plantations
Maintaining biological diversity
Maximizing logging output
15
How did the evolution of Dutch elm disease complicate efforts to breed resistant American elms?
It made the disease only affect older trees
It made the disease less virulent over time
It caused the disease to spread more slowly
It created multiple strains, making resistance to all strains difficult
16
When we calculated with a ruler the height of our trees, why did it not take the last 15-20 feet?
It was operator error

It had no significant impact
It improved soil quality
19
How do forests contribute to water quality?
They have no impact on water quality
They increase water temperature
They filter pollutants and regulate water flow
hey reduce groundwater recharge
