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)
Case Study - Mining Effects on AnglingEstimating Demand in the Absence of Use Data
Fishing Days Demanded by Origin (DDO)
Urban days demanded Rural days demanded
= Population ∙ Participation Rates (by demographic
segment) ∙ Days per Participant (by urban/rural)

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
