Question 1

Sustainable forest management________.

Accepted Answer

Sustainable forest management includes varied uneven-aged management approaches to maintain ecological balance and biodiversity, rather than focusing solely on harvesting methods.

Question 2

High grading can be defined as_______.

Accepted Answer

High grading refers to the practice of selectively removing the most valuable trees from a forest for purposes such as fuel and construction, often leading to ecological imbalance.

Question 3

Allocation is_______.

Accepted Answer

Allocation refers to the management of the location and relative amounts of different forest uses, ensuring that resources are distributed and utilized effectively for various purposes.

Question 4

Complete removal of the forest canopy is_______.

Accepted Answer

Clear-cutting involves the complete removal of the forest canopy, leaving the area devoid of trees.

Question 5

Forests provide habitat for _______of all terrestrial species.

Accepted Answer

Forests are home to a significant portion of the world's terrestrial species, with estimates suggesting that they provide habitat for 60-80% of these species.

Question 6

The best approach for slowing worldwide deforestation will require_______.

Accepted Answer

A comprehensive approach involving multiple strategies is necessary to address the complex and varied causes of deforestation globally.

Question 7

Wood consumption by humans in developing countries is primarily used for_______.

Accepted Answer

In developing countries, wood is primarily used as a source of fuel for cooking and heating due to limited access to alternative energy sources.

Question 8

The seeds of conifer trees are found in _______	.

Accepted Answer

Conifer trees produce seeds in cones, which are their reproductive structures.

Question 9

Field experiments studying the effects of increased CO₂on forest growth have shown_______.

Accepted Answer

Increased CO2 can enhance forest growth, but this effect is often contingent on the availability of other essential resources like nitrogen and water. Without these, the growth benefits of elevated CO2 may not be realized.

Question 10

The establishment stage of forest development following disturbance can be described as_______.

Accepted Answer

The establishment stage involves tree seedlings germinating on the recently cleared ground after a disturbance, initiating the process of forest regeneration.

Question 11

Primary plant/tree growth is characterized mainly by_______.

Accepted Answer

Primary growth in plants is characterized by the elongation of the plant body, which occurs due to cell division at the apical meristems located at the tips of roots and shoots, leading to upward and downward growth.

Question 12

Ten thousand years ago, forests covered approximately 50% of Earth. Today, forests cover approximately 	_______of the Earth's land area.

Accepted Answer

Today, forests cover approximately 30% of the Earth's land area. This is due to deforestation and land use changes over the millennia.

Question 13

Currently, the most economically valuable non- wood commodity to be harvested from forests is_______

Accepted Answer

The answer of Currently, the most economically valuable non- wood...

Question 14

Primary forests_______.

Accepted Answer

Primary forests are largely unaffected by humans, meaning they have not been significantly disturbed or altered by human activity.

Question 15

Rotation time in a forest depends on________.

Accepted Answer

The answer of Rotation time in a forest depends on________.
...

Question 16

Which of the following is a way in which humans pay directly for the ecosystem services forests provide?

Accepted Answer

Ecotourism is a way humans pay directly for ecosystem services, as people spend money to visit and experience natural environments, thereby supporting conservation and local economies.

Question 17

Which of the following forest products would you expect to have the best potential for sustainable use?

Accepted Answer

The answer of Which of the following forest products would...

Question 18

Life of a single tree begins with a(n)_______.

Accepted Answer

A single tree begins its life from a seed, which germinates and grows into a tree.

Question 19

Which tree species is most widely used for the purpose of making paper?

Accepted Answer

Pine trees are most widely used for paper production due to their fast growth, availability, and the quality of fibers they produce, which are suitable for making paper.

Question 20

What percentage of wood harvested in Africa is consumed for fuel?

Accepted Answer

90% of wood harvested in Africa is consumed for fuel, primarily for cooking and heating purposes.
