Our Proposals:
Strategy 1:
30,000 hectares of land will be separated into 4 quadrants by road. There will be a three street running E-W through the land (Rt. 22). There will also be a road (sawmill road) that runs N-S; the northern part of the sawmill road will be closed from public access. The Northern portions of the land will be separated into approximately 10,000 ha each. The southern portions of the land will be separated into 5,000 ha each. 70 birds will be placed on each portion of land that is 10,000 ha and 30 birds will be placed on each portion of land that is 5,000 ha. In initial year of operation, we will cut down 2550 m3 of wood (not trees) from edges of quadrants containing 10,000 ha (cutting smaller amounts of tree during the non-breeding season that in breeding season) and 53,950 m3 of wood from quadrants containing 5,000 ha. The total number of trees cut will be restored with 3/4 of those being 100 yr rotation mahogany trees and 1/4 being eucalyptus trees. The mahogany trees will be grown for 80 yrs (after 80 yrs, only 1/4 of these trees harvested in the 1st yr of operation will be used for timber. With the technique of individual-selection harvesting, we allow mahogany trees to grow into maturity
Advantages and disadvantages
Placing the parrots in the middle of the quadrant will allow additional wood to be cut down and allow prevent birds from being hurt during deforestation. This can protect the parrots from major catastrophes such as a fire, causing a border to be set and help the fire to be contained within the area. However, it may be difficult to determine which trees (non-breed, breeding) were harvested at any time. Since bird dispersal cannot be properly controlled, birds may indeed be killed during deforestation and habitats may be destroyed also. The bird population may also increase, limiting the amount of space for each bird and causing the carrying capacity to be overshot.
Sawmill
Strategy 2:
30,000 ha will produce about 6,000,000 ha of timber annually. With this knowledge, the forest will still be separated into 4 quadrants, with the exception of the fenced parrot habitat along the north end of the land. The 200 parrots (100 breeding pairs) will have about 24,000 ha of breeding and non-breeding area. Instead of a three street running E-W through the land, there will be a 4 street land.. Two long roads will from E to W will be separated by the sawmill in the southern road.
The area in the N-S end will have two short roads; the N end will allow forest managers access to the parrot habitat and the S end will allow for both parking and wood transfer. With the remaining 6,000 ha of forest, the remaining quadrants of the land will be separated as follows: W 2,000 ha, E 2,000 ha and S 2,000 ha. In each quadrant, the outline of the deforestation areas will contain eucalyptus trees while in the center, mahogany trees.
Advantages and disadvantages
With
the parrot habitat properly controlled and gated, this can prevent poachers and
other unauthorized people from entering into the land and also prevent harm done
to the animals during deforestation. This insures the cockatoo safety within the
forest. This border with an even dispersal of the trees, allows the birds in
various age sets to easily migrate from one place to the next. This also
prevents parrot habitat from fire and other disturbances throughout the year.
This however may not allow the animals enough space to evenly disperse, and may
cause intraspecific competition within the habitat. This also provides
difficulty in prescribed burning, making open canopies within the forest and
allowing mahogany seeds to grow into maturity.
