Slide 13: Operating cost per various park sizes
This graph shows the relationship between the operating costs per km2(X-axis) and the park size. From the graph it can be seen that smaller areas clearly have a higher operating cost compared with larger areas. This is due to economies of scale, which carry over into many facets of park management, Furthermore, areas within larger parks are often more inaccessible, which means that there is less human impact and therefore less management required for these areas. Ecological monitoring is essential in smaller parks, since change can occur very rapidly over a small area, whilst the concomitant costs are greatly reduced for larger parks. Thus there is a need to identify optimal park size.
