Wildlife Habitat Benefits Estimation Toolkit Spreadsheet-based valuation models Value databases & peer-reviewed studies of ecosystems and species Recreation use model Technical reports & user’s manual

The WHBE Toolkit ₊ Increases in property value from nearby open space ₊ Outdoor recreation associated with wildlife ₊ Conservation of threatened & endangered species ₊ Some ecosystem services, using ‘benefits transfer’ = Total conservation value of a site for wildlife + habitat

How the Toolkit works: pros & cons Pros Synthesizes information from many studies Straightforward data needs Useful for rapid assessment, cheaper than new studies Cons Requires some technical expertise Not specifically designed for business applications Values derived from other study sites can be inaccurate

Natural Capital Project: InVEST Integrated Valuation of Ecosystem Services and Tradeoffs Family of models that enables users to quantify, map and value the ecosystem service impacts of alternative decisions. Maps, tradeoff curves, balance sheets

Lands and waters: Carbon Hydropower Water purification Reservoir sedimentation Managed timber production Crop pollination Oceans and coasts: Wave energy Coastal hazards Aquaculture Aesthetic views Biodiversity Ecosystem Services

Measures & Values Supply of service Demand/use of service Valuation Market valuation Avoided damage costs Production Economics

How InVEST works: pros & cons Results Pros Spatially explicit results comparing options Good for addressing multiple benefits & risks Cons Requires technical expertise, data & time Not specifically designed for business applications Without reliable, precise input data, values derived can be inaccurate

Project Work Flow Project team 3 technical team, 2 reporting team, 2 Lafarge team, review from NatCap Timeline 5 months, kick-off, monthly calls, final presentation Tools 4 models, 1 report Cost Under $60,000

Results: Habitat Benefits
