Question 1

The two main categories of methods for determining the allowance reduction are area control and ____  .

Accepted Answer

volume control

Answer

In sustainable forest management, the 'allowance reduction' or 'allowable cut' refers to the maximum volume of timber that can be harvested from a forest over a specific period without compromising its long-term productivity. The two primary methods for determining this sustainable harvest level are area control, which regulates the size of the area harvested, and volume control, which directly regulates the quantity (volume) of timber removed.

Question 2

Slope is a fundamental factor in determining how to classify land. The maximum gradient often permitted for disposable and alienable lands is:

Accepted Answer

17 percent

Answer

Land classification systems, particularly in the Philippines, often define maximum slope gradients for different land uses to manage erosion risk and ensure sustainability. A slope of 17 percent typically falls within the permissible gradient for 'disposable and alienable lands,' meaning areas that can be privately owned or disposed of by the state, as steeper slopes are generally classified for forest protection or other restricted uses.

Question 3

According to government laws, the highest gradient of areas that can be used for grazing is:

Accepted Answer

49 percent

Answer

Government regulations for land use often specify maximum slope gradients to prevent soil degradation and erosion. While 49 percent (or 50 percent) represents a steep slope, certain types of extensive grazing can be permitted on such gradients, provided that appropriate soil conservation measures are implemented. Steeper slopes are typically designated for strict forest protection to maintain ecological stability.

Question 4

Aerial images are excellent for:

Accepted Answer

timber inventories

Answer

Aerial images, including satellite imagery and drone photography, are invaluable tools for timber inventories. They allow foresters to efficiently assess large forest areas, identify different tree species, estimate stand density, and even approximate tree heights and crown diameters. This remote sensing capability significantly reduces the time and cost associated with traditional ground-based surveys.

Question 5

When a water is crucial, it means that:

Accepted Answer

supporting a multipurpose dam and in need of reforestation

Answer

A 'critical watershed' is one whose ecological health and hydrological function are essential for supporting vital downstream resources, often including a multipurpose dam that relies on consistent water flow for power generation, irrigation, or water supply. Such watersheds are typically degraded and therefore require immediate reforestation and other conservation efforts to restore their functions and protect the dam's longevity and the resources it provides.
