Development of a spatial harvest scheduling system to promote the conservation between indigenous and exotic forests
The model was demonstrated using 8 arbitrary scenarios on a 1905 ha forested area using a simulated data set. The minimum shifting mosaic areas used in these scenarios were: 650, 850, 1050 and 1250ha. The goal for maximizing interior habitat was expressed as a perimeter goal, which compared the ratio of the perimeter of the shifting mosaic area with the perimeter of a circle with equal area. Two values were used for this analysis; one was twice the perimeter of a circle with equal area while the other set the value to 3.33 times the value of a circle with equivalent area. The highest level of protection from these scenarios, a minimum shifting mosaic area of 1250 ha with either perimeter goal, produces approximately 50% less discounted net revenue than the non spatially constrained solution. The smallest shifting mosaic area, 650 ha, lowered discounted net revenue between 16% for the 3.33 perimeter goal and 27% for the 2.0 perimeter goal. These models are useful for policy makers to begin to develop the cost and benefits from various levels of biodiversity protection.
