Slide 7: Determinants of cost of PAN
Many factors determine the cost of setting up and running protected area networks. First amongst these is size - whilst larger protected areas are obviously more expensive, the unit cost tends to drop because of the easier functioning of the whole. The vegetation type and dominant habitat class are important factors as well, since open biomes are more expensive to manage. This is on account of their accessibility - the more people that impact on a biomes, the more expense involved in maintaining it. The extent of land transformation obviously has associated costs, since highly transformed land typically requires high restoration costs, and even though the land may be cheap to purchase, the total acquisition costs are driven up. Finally, the land use in the surrounding area is important, because of edge effects on the PAN. Thus, the engagement of neighboring communities in the conservation process through community based natural resource management is essential.
