Natural Resources
Renewable or non renewable
Natural resources can be divided into two categories renewable and non renewable. Resources in the non renewable category are menireal resources such as iron, copper, lead, uranium and aluminium and fossil fiels such as oil, coal and natural gas. While we may have an ample suplly of hese non renewable resources for many years to come, they are a finite resources. A non renewable resource is one which, once the available supply has been used cannot be replenished. Conversely renewable resources are those which with proper management and care can be utilized indefinitely.
Forest, wildlife, water and soil are renewable natural resources. However all renewable natural resources are vulnerable to abuse. For example once a wildlife species’ habitat becomes fragmented (that is broken up into small isolated pockets) and its numbers drop below a certain number, it is almost certainly doomed to extinction. An example of this would be the passenger pigeon mentionen. Unfortunately dozens of other species have already gone the way of the passenger pigeon. However, wildlife is a renewable natural resources. With proper management of wildlife and wildlife habitat, we can enjoy an abundance of wildlife for generations to come. Forest resources or timber are also renewable resources. If we manage our forest in such a way as to plant as many or more acres than we harvest, then we will continue to have a bountiful timber harvest.
Over 90 countries now participate in the Convention on International Trade on endangered species of wildlife fauna and flora _CITES. This is an international treaty designed to prevent the exploitation of rare wildlife from commercial trade.

Some of the habitat management practices that directly benefit wildlife include
a. Food plot and planting known to be used by wildlife. This is benefiacial for most wildlife
b. Half cutting brush or building brush piles This benefits species such as rabbit which will use structures for shelter.
c. Artificial nesting structures. This benefits species such as wood ducks and geese.
d. Controlled burns. This promotes the growth of new grasses and forbs used by such species as white tailed deer
e. Timber cutting, if dones as smaller clear cuts or selective cutting. This opens up the forest floor, allowing grasses, scrubs and other species as turkeys, elk and white tailed deer
f. Grazing by livestock. If done in moderation it cuts back or slows plant growth, allowing growth of browse plant and easier travel for ground dwelling wildlife such as bobwhite quil
g. Providing water sources
h. Mechanical alteration (meminda) of habitat. This promotes weed growth that attract insect.
i. Farming .provides food and cover. Beneficial to many ground dwelling species such as field mice, pheasant and meadowlarks (sejenis burung di padang rumput…)
