Free Bachelor of Forestry Forest Production Management Questions and Answers — Questions and Answers

Question 1: The two main categories of methods for determining the allowance reduction are area control and ____ .

volume control (Correct answer)
numbers of trees
marking goal

Correct answer: volume control

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:

17 percent (Correct answer)
15 percent
19 percent
10 percent

Correct answer: 17 percent

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:

18 percent
20 percent
49 percent (Correct answer)
40 percent

Correct answer: 49 percent

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:

timber inventories (Correct answer)
land capability surveys
streamflow gauging
wildlife surveys

Correct answer: timber inventories

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:

erosion is prevalent
in need of immediate reforestation
supporting a logging business
supporting a multipurpose dam and in need of reforestation (Correct answer)

Correct answer: supporting a multipurpose dam and in need of reforestation

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.

Question 6: Planning for land use entails:

land capability evaluation
land suitability classification
land-use allocation
all of these choices (Correct answer)

Correct answer: all of these choices

Land use planning is a comprehensive process that involves several key steps. It begins with evaluating the inherent capabilities of the land (land capability evaluation) to understand what it can sustainably support. This leads to classifying its suitability for various uses (land suitability classification), considering both biophysical and socio-economic factors. Finally, based on these evaluations, specific uses are assigned to different areas (land-use allocation) to optimize resource management and achieve desired objectives.

Question 7: The following vertical expose is made into a sizable photogram that resembles a single print by cutting, matching, and pasting several together:

aerial map
photomosaic (Correct answer)
photographic map
aeril photo

Correct answer: photomosaic

A photomosaic is created by assembling multiple individual aerial photographs, often taken with some overlap, into a single, continuous image. This process involves cutting, matching, and pasting the prints to eliminate overlaps and create a seamless representation of a larger area. The resulting mosaic provides a broader perspective than a single photograph, useful for mapping and land analysis.

Question 8: According to the selective logging methodology, healthy residuals should be:

located along cableways
concentrated along the setup boundary
concentrated around the spar tree
distributed around the spar tree (Correct answer)

Correct answer: distributed around the spar tree

In selective logging, the goal is to harvest mature or defective trees while leaving healthy, vigorous trees to continue growing and regenerate the stand. Distributing healthy residuals around the spar tree (or logging setup) ensures that the remaining forest structure is maintained evenly across the harvested area. This promotes natural regeneration, minimizes soil disturbance, and preserves biodiversity, contributing to sustainable forest management.

Question 9: A technique for taking live specimens of a certain animal species while doing a wildlife inventory-

quadrat method
trapping (Correct answer)
rapid visual survey
shooting

Correct answer: trapping

Trapping is a common and effective method for capturing live animal specimens during a wildlife inventory. This technique allows researchers to collect data such as species identification, age, sex, health, and to mark animals for future identification without harming them. The captured animals are typically released after data collection, making it a valuable tool for ecological studies and population monitoring.

Question 10: TSI's objectives are to:

Improve site quality
produce high-quality (Correct answer)
improve water yield
prevent the incidence of pest

Correct answer: produce high-quality

TSI stands for Timber Stand Improvement, which refers to forestry practices aimed at enhancing the growth and quality of desirable trees in a forest stand. The primary objective is to produce high-quality timber by removing undesirable trees (e.g., diseased, poorly formed, or competing species) and promoting the growth of healthy, commercially valuable trees. This leads to a more productive and valuable forest over time.

Question 11: The Bureau of is in charge of dividing public domain lands into forestlands and alienable and disposal areas.

Fisheries
Soils
Forest Development
Lands (Correct answer)

Correct answer: Lands

In many countries, the Bureau of Lands (or a similar land management agency) is primarily responsible for the administration and disposition of public domain lands. This includes the crucial task of classifying and delineating these lands into categories such as forestlands (which are typically inalienable) and alienable and disposable lands (which can be privately owned or disposed of). This classification is fundamental for land use planning and resource management.

Question 12: The following one cannot be used to gauge the financial or commercial worth of forest resources or land

Net present value
Internal rate of return
Benefit- cost ratio
Consumer index (Correct answer)

Correct answer: Consumer index

Financial valuation methods like Net Present Value (NPV), Internal Rate of Return (IRR), and Benefit-Cost Ratio (BCR) are standard tools used to assess the profitability and economic worth of investments, including forest resources and land. The Consumer Price Index (CPI) or similar consumer indices, however, measure changes in the price level of consumer goods and services over time. They are indicators of inflation and purchasing power, not direct measures of the financial or commercial worth of specific assets like forest resources.

Question 13: "Log" in a timber inventory means:

the lenght of a standing tree
a felled tree
5-meter section of log (Correct answer)
a standing tree

Correct answer: 5-meter section of log

In timber inventory and forestry measurements, a "log" often refers to a standardized section of a felled tree, typically measured in specific lengths for commercial purposes. While the exact length can vary by region or industry standard, a 5-meter section is a common unit used for calculating timber volume and value. This standardization simplifies inventory calculations and trade.

Question 14: A group of trees with adequate consistency in terms of composition, age, and spatial arrangement:

setup
forest stand (Correct answer)
ecosystem
forest community

Correct answer: forest stand

A forest stand is a contiguous group of trees that possesses sufficient uniformity in species composition, age class, structure, and spatial arrangement to be distinguishable from adjacent groups. This consistency allows foresters to manage it as a single unit for silvicultural treatments, harvesting, and inventory purposes. It is a fundamental unit of forest management.

Question 15: Land that has been claimed as ancestral by:

kaingineros
shifting cultivation
cultural communities (Correct answer)
upland farmers

Correct answer: cultural communities

Ancestral lands are territories traditionally owned, occupied, and utilized by indigenous peoples or cultural communities, often for generations, based on their customs, traditions, and historical ties. These claims are rooted in their cultural identity and traditional resource management practices. Recognizing ancestral domains is crucial for protecting indigenous rights and cultural heritage.

Question 16: Natural stream configuration on a watershed is known as:

drainage basin
aspect
drainage network (Correct answer)
watershed discharge

Correct answer: drainage network

A drainage network refers to the pattern formed by the streams, rivers, and other water bodies within a watershed or drainage basin. This natural configuration is shaped by topography, geology, and hydrology, dictating how water flows across the landscape. Understanding the drainage network is essential for watershed management, flood control, and water resource planning.
