Amount of forage added = 500 lb/acHarvest Rate = 50% -$4.06 NPVForage Value = $14/AUM -0.19% IRRTreatment Cost ($/Ac) = $22/Acre 0.82:1 B/C RatioDiscount Rate = 7%Treatment Life (years) = 5 Years

What the traditional Economic Analysis Shows• Forage production increases 3 to 5 times
• Livestock production benefits alone do not economically justify the majority of range improvement projects– NPV generally negative
– Livestock production pays for about 50% to 80% of total treatment cost
– Cost share treatments
Major Change in Emphasis
• Millions have recently been spent on restoration cooperative efforts – Land agencies
– Private individuals
– Conservation groups
– NGOs
• Individuals and agencies seek ways to realize non-grazing benefits from rangelands

Restoration and Rangeland Health
New Mexico State University
• Many cooperative efforts for rangeland restoration– Sage grouse habitat
– Fire prevention and fuels management
– Healthy Rangelands
Restore New Mexico is a Cooperative Effort lead by New
Mexico BLM
New Mexico Quail, Inc.

The NRCS Conservation Effects Assessment Project (CEAP) - 2011
• Literature Review
• Assess and quantify the effects of conservation practices– Prescribed Grazing
– Prescribed Burning
– Brush Management
– Range Planting
– Wildlife Habitat Improvement
– Weed Control

CEAP Project Economic Findings
• Benefit/Cost Assessment:– Societal benefits from ecosystem services and
multiple uses are an increasing priority influencing public land use decisions
– Economic consideration of nonmarket ecosystem services is essential for improved investment decisions for conservation programs
New Mexico State University
We know very little about the economics of rangeland ecosystem services for Multiple Uses• Wildlife habitat improvement
• Watershed benefits
• Carbon sequestration
• Reduced fire hazard

Sparrowk Livestock Conservation Efforts
• Stream Restoration• Willow Restoration• Timed grazing of Riparian areas
Conservation Practices
• Water Quality• Wildlife habitat• Aquatic Habitat
Benefits
• How much more?• How does society value the change?
• Can SparrowkLivestock economically benefit?

Putting an economic value on ecosystem services
Two types of information needed:1. Changes in rangeland output levels
(resource effects, weak link)
2. People’s valuation of those outputs

Procedures for Valuing Ecosystem Services• Market value and productivity
• Contingent valuation and choices– Ask people their willingness to pay
– Scenario preferences
• Travel cost method
• Replacement cost– Cost of removing sediments
• Hedonic pricing models
Some Ecosystem Services provided from rangeland improvements are major
• Livestock benefits
• Improved wildlife habitat and numbers
• Reduced sediment and runoff
• Weed control
• Landscape scenic appeal

We know little about the economics of ecosystem services
We are implementing restoration projects because decision makers think it is the right thing to do!• Economic justification is very
limited and not forthcoming

We know little about the economics of ecosystem services
The failure to economically value ecosystem services means we undervalue the net benefits of investments in conservation
