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

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,
