Carrying capacity The level of use that a resource, site or facility can support before suffering significant deterioration. Three types of carrying capacity. • Physical capacity - the maximum number of people able to use a resource at any one time. For example a theatre has a certain number of seats. (NB throughput capacity). • Ecological capacity - the threshold of people using a site beyond which damage to the environment will occur. For example eroded footpaths. • Perceptual capacity - the level of usage at which point the enjoyment of the leisure experience is diminished for the consumer or host community. For example the number of people on a beach that is “too crowded”. • Progressively difficult to measure. • Carrying capacity can vary due to opinion, management techniques or the nature/fragility of a resource. Explain why the physical, ecological & perceptual carrying capacities will vary for Westminster Abbey, Wembley stadium, the summit of Snowdon & Dove Cottage (Wordsworth’s home).
