What is Parks?
A. Natural areas, small exploitation by human because of beauty of their landscapes.
B. Contain diversity of flora and fauna.
C. Provide the scientific values for education, aesthetic, ecological processes, recreational areas.
D. Conservation areas which habitat for only endemic and/or endangered tropical plant species.
Why do we need to conserve?
B. Natural sources have been seriously depleted.
C. Sustain the natural resources for the future generation.
D. Management of nature for scientific purpose.
We need to conserve because natural sources have been seriously depleted. This means that our natural resources are being used up at a faster rate than they can replenish themselves, leading to scarcity and potential environmental damage. Conserving these resources ensures their availability for future generations. Additionally, managing nature for scientific purposes is important as it allows us to understand and study the natural world, leading to advancements in various fields.
What is scientific values of Parks?
D. Surveys and inventories of parks are essentially important.
The scientific values of parks are important because they allow for surveys and inventories to be conducted. These surveys and inventories help in understanding the natural and cultural significance of the protected areas. They provide valuable data and information that can be used for research, conservation, and management purposes. By conducting surveys and inventories, scientists and researchers can gather data on biodiversity, ecosystem health, and cultural heritage, among other things. This information is crucial for making informed decisions and taking appropriate actions to protect and manage the parks effectively.
According to IUCN (1996), protected areas is defined as "An area of land and/or sea especially dedicated to the protection of biological diversity and natural and associated cultural resources that managed through legal or other effective means".
The given statement is true. According to the International Union for Conservation of Nature (IUCN) in 1996, protected areas are defined as areas of land and/or sea that are specifically dedicated to the preservation of biological diversity and natural and associated cultural resources. These areas are managed through legal or other effective means. This definition highlights the importance of protecting and conserving the environment and its resources through designated areas that are managed and regulated to ensure their preservation.
Benefits provided by protected areas
A. Soil regeneration
B. Control of biological pest
D. Provision of clean air
E. Nutrient cycling
Protected areas provide a range of benefits. They contribute to soil regeneration by preserving natural ecosystems and preventing soil erosion. They also help control biological pests by maintaining the balance of predator-prey relationships and preserving natural habitats for beneficial organisms. Protected areas offer opportunities for recreation, allowing people to enjoy nature and engage in outdoor activities. They also contribute to the provision of clean air by preserving forests and other vegetation that absorb carbon dioxide and release oxygen. Additionally, protected areas support nutrient cycling by maintaining diverse ecosystems that facilitate the recycling of nutrients through decomposition and nutrient uptake by plants.
According to UN (2008), sustainable forest management (SFM) is characterised by 7 elements, such:
Why it is important to evaluate resources for natural resources planning?
A. Understand the common financial criteria used in forest resource management for making decision.
B. Understanding the basic concept of estimating future and present values.
C. To review implementation of natural resources projects.
D. Understanding the plethora of biological measures for evaluating the structural conditions of a forest before and after planned management activities.
It is important to evaluate resources for natural resources planning in order to understand the common financial criteria used in forest resource management for making decisions. This helps in making informed choices regarding the allocation of resources and the financial viability of the project. Additionally, understanding the basic concept of estimating future and present values is crucial for effective planning and resource allocation. Evaluating resources also allows for the review of the implementation of natural resources projects and ensures that they are being carried out effectively. Lastly, understanding the plethora of biological measures for evaluating the structural conditions of a forest before and after planned management activities helps in assessing the impact of these activities on the ecosystem.
What are the structural evaluation of forest resources?
A. Tree per unit area
C. Stocking and density
D. Canopy cover
E. Basal area
F. Average diameter of trees
The structural evaluation of forest resources involves assessing various aspects such as the number of trees per unit area, the amount of biomass present, the stocking and density of trees, the extent of canopy cover, the basal area (cross-sectional area of tree trunks at breast height), and the average diameter of trees. These parameters provide valuable information about the health, productivity, and overall condition of the forest ecosystem.
The use value can be divided into three (1), (2) and (3). For example (2) is ecosystem functional benefits such as watershed protection and timber protection.
The use value can be divided into three categories: direct value, indirect value, and option value. Direct value refers to the immediate benefits that can be obtained from a resource, such as the use of timber for construction. Indirect value refers to the ecosystem services provided by a resource, such as watershed protection and timber protection. Option value refers to the potential future benefits that can be derived from a resource, such as the use of medicinal plants for future medical discoveries.
