Natural Capital Project Goals
1. Quantify and value the full set of goods and services from ecosystems under alternative land use scenarios

NEEDED• region/landscape scale
• spatially explicit• multiple services
Appropriate scale for land use decisions
– How would a proposed dam or logging project affect different ecosystem services and biodiversity?
– What landscape pattern would optimize ecosystem services now and under likely scenarios?
– How should corporate landholdings be managed to maximize return on assets?
– Who should pay whom under a proposed PES program?

InVEST
1) what is InVEST?2) how is a large private
landowner using it?3) how can it inform
incentives?
• Multiple services• Spatially explicit• Flexible and transferable• Biophysical and economic terms• Driven by future scenarios
InVEST Integrated Valuation of Ecosystem Services & Tradeoffs
InVEST 1.0 Beta can map
Biodiversity
Crop pollination
Carbon storage & sequestration
Water pollution regulation
Managed timber production
Avoided reservoir sedimentation
The next version of InVEST will add
Irrigation
Flood mitigation
Agricultural production
Hydropower production
Open access products (NTFPs)
Tourism and recreation
Management– Water release schedule– Fertilizer application rate
Climate Change– Land cover change – Precipitation and temperature
Population Growth– Land cover change– Increased demand

But, what should this landscape look like in the future to meet all these goals?

What is the flow of ecosystem services on today’s landscape?
How might these service flows change in the future?
