The term sustainable yield is most commonly used in forestry, fisheries, and groundwater applications. Sustainable yield is an important component of sustainable forest management. In the forestry context it is the largest amount of harvest activity that can occur without degrading the productivity of the stock .
What is sustained yield in forestry?
: production of a biological resource (such as timber or fish) under management procedures which ensure replacement of the part harvested by regrowth or reproduction before another harvest occurs.
How does yield management relate to forestry?
The term sustainable yield is most commonly used in forestry, fisheries, and groundwater applications. Sustainable yield is an important component of sustainable forest management. In the forestry context it is the largest amount of harvest activity that can occur without degrading the productivity of the stock .
How can forests provide a sustainable yield?
The term sustainable yield is most commonly used in forestry, fisheries, and groundwater applications. Sustainable yield is an important component of sustainable forest management. In the forestry context it is the largest amount of harvest activity that can occur without degrading the productivity of the stock.
What is meant by sustained yield forest management?
: production of a biological resource (such as timber or fish) under management procedures which ensure replacement of the part harvested by regrowth or reproduction before another harvest occurs .
What is maximum sustainable yield in forestry?
The term sustainable yield is most commonly used in forestry, fisheries, and groundwater applications. ... In the forestry context it is the largest amount of harvest activity that can occur without degrading the productivity of the stock.
What do you mean by forest management?
Forest management focuses on managing vegetation, restoring ecosystems, reducing hazards, and maintaining forest health .
What is sustained yield concept?
The term sustainable yield refers to the harvest of a specific (self-renewing) natural resource—for example, timber or fish. Such a yield is one that can in principle be maintained indefinitely because it can be supported by the regenerative capacities of the underlying natural system.
What is meant by the maximum sustainable yield?
Maximum sustainable yield (or MSY) is the maximum catch that can be extracted from a fish or other population in the long term .
How do you calculate sustainable yield?
If stock size is maintained at half its carrying capacity , the population growth rate is fastest, and sustainable yield is greatest (Maximum Sustainable Yield). K = unfished stock biomass at carrying capacity r = intrinsic rate of stock growth.
What is rotation in forest management?
The biological rotation approach determines the optimal time at which a forest stand can be harvested to maximize timber production . However, this approach ignores costs and revenues that can be obtained from the forest. The net present value (NPV) determines the value of a forest stand considering a single rotation.
What does it mean to sustain the environment?
Environmental sustainability is the responsibility to conserve natural resources and protect global ecosystems to support health and wellbeing, now and in the future.
What is the normal forest?
“A normal forest is a forest which has reached and maintains a practically attainable degree of perfection in all its parts for the full and continued satisfaction of the objects of mgt.” A normal forest is a yardstick (means standard of comparison) for our actual forest and tells us shortcomings of our forest.
Is maximum sustainable yield efficient?
The maximum sustainable yield is usually higher than the optimum sustainable yield and maximum economic yield . MSY is extensively used for fisheries management. Unlike the logistic (Schaefer) model, MSY has been refined in most modern fisheries models and occurs at around 30% of the unexploited population size.
What is growing stock in forestry?
In forestry, live standing trees in a forest are known as growing stock. ... Typically AGS includes trees that are held for future harvest and are still adding wood volume. These trees are retained for future benefit or sale.
Is it possible to reach sustainable wood yield?
Sustained yield requires delib erate and persistent management. It is not achieved easily . Central to sustained yield is the ‘rotation’, a concept that applies both to individual trees and to stands. A rotation is the period between tree establishment and the age at which the oldest tree is harvested.
