The management strategy changed from setting an annual total allowable catch (TAC) and allowing the fishing fleet to fish until the TAC was reached. In 1990 the fishing season was only 6 days, most of the fish caught had to be frozen, gear was lost or damaged, and crews were endangered when the weather was bad. Now the individual quota system is used, so owners of fishing vessels can decide when to fish within a season that last(s) as long as 8 months.
The fishers got an increase in income and could fish in better weather, and losing less fishing gear. 2. A natural area will receive protection only if the value a society assigns to services provided in its natural state is higher than the value the society assigns to converting it to a more direct human use. 3. Ecosystem capital includes the goods and services produced by the species within an ecosystem and the interactions between the biotic and abiotic portions of ecosystems. Ecosystems are expected to produce something of economic value.
Natural resources are only those items in an ecosystem that have a monetary value and things with a monetary value are not a resource. Ecosystem capital does not require that a monetary value is known or exists. All that matters with ecosystem capital is that there is ecological value. 4. Conservation of natural biotas and ecosystems does not—or at least should not—imply no use by humans whatsoever, although this may sometimes be temporarily expedient in a management program to allow a certain species to recover its numbers.

Rather, the aim of conservation is to manage or regulate use so that it does not exceed the capacity of the species or system to renew itself. The objective of preservation of species and ecosystems is to ensure their continuity, regardless of their potential utility. Therefore, a second-growth forest can be conserved but an old-growth forest must be preserved. 5. Productive is the exploitation of ecosystem resources for economic gain. Therefore products such as timber and fish are harvested and sold for national or international markets.
Consumptive use is when people harvest natural resources in order to provide for their needs for food, shelter, tools, fuel, and clothing. Thus, people are hunting for game, fishing, or gathering fruits and nuts in order to meet their food needs, or else they are gathering natural products like firewood, forage for animals, or wood and palm leaves to construct shelters or to use as traditional medicines. 6. Maximum sustained yield is the highest possible rate of use that the system can match with its own rate of replacement or maintenance.
The problem with implementing maximum sustained yield is that we do not know the highest recruitment rate for a species with a specified ecosystem but we make decisions as if we do know. The optimal population size to obtain maximum sustained yield is one half of the size that it would be at the carrying capacity. We do not know an ecosystem’s carry capacity for various species. Additionally, the carrying capacity will vary from year to year. When the maximum sustained yield is exceeded, the availability of the resource declines. 7.
The tragedy of the commons is an exploitation of common pools of resources, which can lead to the eventual ruin of these resources. Overcutting and deforestation in forest biomes is an example of misusing a resource. To protect these, the common pool’s resources must be maintained so that it can yield benefits for both the present and future. 8. Restoration efforts are needed when a pool of resources has been damaged to the point where people must help it to recover, so that normal ecosystem integrity, resilience, and productivity return.
The Comprehensive Everglades Restoration Plan (CERP) is trying to restore the Florida Everglades. It is expected to take 36 years and $7. 8 billion to complete, and the State of Florida is working with the national government to achieve the goals set in this plan and return the everglades, which are home to many endangered and diverse species, to its former glory. 9. The major findings of the Forest Resources Assessment 2000 are: * In 2000, the world’s forest cover was 3. 6 billion hectares, which is 400 million hectares more than was reported in 1996, though this is due to more accurate coverage and a redefinition of forests in developed countries rather than actual forest growth. * Deforestation is continuing in developing countries, but forest cover is remaining stable in developed countries. * El Nino caused many droughts in the late 90s, which in turn led to fires burning down millions of hectares of forests. 1998 was called “the year the earth caught fire. * About 10% of forests are protected as national parks or reserves, with the largest percentages in the Americas and the least in Europe. * Forests have four major roles in climate change, acknowledged in November 2001: 1. They are a source of carbon dioxide when burned or degraded 2. They can be a sensitive indicator of changing climate 3. They are a renewable energy source to replace fossil fuels 4. They are a carbon sink, by taking carbon dioxide from the atmosphere and storing it in biomass and soils. 0. With even-aged management, trees of a fairly uniform age are managed until the point of harvest, cut down, and then replanted, with the objective of continuing this cycle in a dependable sequence. Clear-cutting is typically used for even-aged management, where the trees are all cut at once, and then replanted. Uneven-aged management, on the other hand, does not replant or manage trees, and simply only cuts down certain trees and lets the forest naturally replenish the trees.
The Term Paper on Forest Ecology and Management
The 3 A 3 km patches. Fig. 2 gives the periodic 11-year mean annual MODIS driven NPP across the country and demonstrates the advantage of a ‘‘space based’’ satellite driven approach that provides continuous cover in productivity of every km2 of Austrian forest land. Different daily climate data sets are available for deriving MODIS NPP estimates. Thus we next explored the impact in using different ...
This allows for a more diverse forest and requires more active management and skill, but leaves behind a functional ecosystem and is, in theory, sustainable. The sustainable forestry initiative, which has been widely adopted in the United States, focuses on: * Sustainable Forestry- getting the wood we need, but also managing and taking care of the ecosystem, including soil, air quality, wildlife, and aesthetics. * Responsible Practices- forestry practices that are economically and environmentally responsible. Forest Health and Productivity- protecting forests from wildfire, pests, diseases, and other damaging agents in order to maintain and improve long-term forest health and productivity. * Protecting Special Sites- managing forests and lands that are of a special significance in a manner that takes into account their unique qualities. * Continuous Improvement- continually improving the practice of forest management and measuring the success of the association’s members in achieving the goals of sustainable forestry. 11. Deforestation is the removal of forests and replacement by another land use.
The Essay on Controversial Role of Marine Protected Areas in Fisheries Management
Marine protected areas (MPA) refer to the zones in which human activity has been placed under some restrictions for protection and restoration of the natural environment, its surrounding waters and the occupant ecosystems, and any cultural or historical resources that may require preservation or management. They play a dominant role in protecting marine biodiversity, ecosystem function and ...
Deforestation, which is most prevalent in developing countries, is caused by a county’s need for economic development and rapid population growth, and most of the land is converted to pastures and agriculture. Encouraging trends in the developing world include sustainable forest management, plantations of trees for wood or other products, extractive reserves that yield non-timber goods, preserving forests as a part of national heritage and putting them to use as tourist attractions, putting forests under the control of indigenous villagers, remote sensing, and the World Bank’s help. 2. Fisheries are currently being overfished and overexploited, and the FAO has concluded that 47% of fish stocks are fully exploited, 18% are overexploited, and 10% are depleted, though some developed nations are trying to prevent overfishing. Aquaculture is still far below capture fisheries in terms of fish caught, but aquaculture has expanded rapidly in the past decade, whereas capture fisheries have stabled off, as their upper limits have been reached. 13.
The Magnuson act established eight regional management councils to watch over fisheries and prevent overfishing while still letting the fishing economy go strong, but as forced to take drastic measures in 1997 due to the large number of fishing boats. The Sustainable Fisheries Act gave a clear mandate for fishery management plans: Depleted fish stocks must be rebuilt and maintained at biologically sustainable levels, using IQs, buying out fishing vessels, and requiring that scientific information be employed in setting yields.
