NATURAL REFORESTATION Reforestation can occur naturally if the area is left largely undisturbed. Native forests are often resilient and may re-establish themselves quickly. Conceptually, it involves taking no active role in reforesting a de-forested area, but rather just letting nature take its course. MANAGED REFORESTATION One debatable issue in managed reforestation is whether or not the succeeding forest will have the same Biodiversity as the original forest. If the forest is replaced with only one species of tree and all other vegetation is prevented from growing back, a Monoculture forest similar to agricultural crops would be the result. However, most reforestation involves the planting of different seedlots of seedlings taken from the area. More frequently multiple species are planted as well. Another important factor is the natural regeneration of a wide variety of plant and animal species that can occur on a Clearcut . In some areas the suppression of forest fires for hundreds of years has resulted in large single aged and single specied forest stands. The logging of small clearcuts and or prescribed burning, actually increases the biodiversity in these areas by creating a greater variety of treestand ages and species. Reforestation need not be only used for recovery of accidentally destroyed forests. In some countries, such as Finland , the forests are ''managed'' by the wood products and Pulp And Paper Industry . In such an arrangement, like other crops, trees are replanted wherever they are cut. In such circumstances, the cutting of trees can be carefully done to allow easier reforestation. In Canada , the wood product and pulp and paper industry systematically replaces many of the trees it cuts, employing large numbers of summer workers for Treeplanting work. CONTRASTED WITH TREE FARMING See Also: Plantation Reforestation is controversial when plantations are established in place of natural forest. In tropical American nations such as Costa Rica and Panama, many thousands of acres of ex-cattle Pasture are being planted with economically valuable tropical Timber species, often with the help of generous local government incentives. Unlike in the US and Canada, where plantations are established for wood pulp and paper, in Costa Rica and Panama and other nations in Central America, plantations are being established to grow timber. For example, in just 20 years, a grow slower than teak in Tropical America but are also extremely valuable. Faster growers include Pine , Eucalyptus , and Gmelina . Reforestation, if several native species are used can provide other benefits in addition to financial returns, including restoration of the soil, rejuvenation of local flora and fauna, and the capturing and sequestering of 38 Tonne s of Carbon Dioxide per Hectare per year.
