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:CarbonHydropowerWater purificationReservoir sedimentationManaged timber productionCrop pollination

Measures & Values

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 NatCapTimeline • 5 months, kick-off, monthly calls, final presentationTools• 4 models, 1 reportCost• Under $60,000
Results: Habitat Benefits
Risks & Opportunities: Water contamination v. purification
