A software programme distributed by the National Coral Reef Institute that uses the Habitat Equivalency Analysis (HEA) method and provides an efficient means of calculating the amount of compensation required to provide services that are equivalent to the interim loss of natural resource services following injury. The programme accepts input of parameters necessary to determine long-term service loss from the injury (injured area size and degree; times of injury, functional shape, and equilibrium; post-injury recovery); parameters to determine long-term service gain from compensatory restoration actions (times of restoration beginning and equilibrium; maximum service level; service gain function shape); and general programme parameters (relative value of lost and gained services, baseline level of lost and gained services, discount rate).
