Benefit Relevant Categories

1. Quality is sufficient Beach is wide enough for recreation

2. Complements - Capital and labor available Boat ramps make boating possible

3. Demand - Users or beneficiaries present / possible # Houses protected (not already protected by seawall)

4. Reliability of the future stream of services Adjacent land is protected

5. Scarcity and substitutability Conservation Priority / no alternative restoration sites

Property ProtectionService Indicator Example

Bridge support

Value of time saved

(?)

Change in wave height at bridge

Reduced days of bridge closure

(? days / yr)

Commuting time saved

(4,000 hr/day)

Conclusions

Potential benefits are often reflected by the relative scarcity of the ecosytem good or service

Use BRIs to:

Demonstrate a service is possible

Characterize the scarcity

Benefit relevant indicators provide context for ecological indicators

Suggest what people might be willing to pay for, given their behavior within and outside of markets
