Dr. Stephanie Shwiff,
Research Economist

Dr. Shwiff is the project leader of the NWRC's Economic Research of Human Wildlife Conflicts project. Her main research interests, publications and presentations involve the estimation of the economic impacts of invasive species and wildlife transmitted diseases. Other research includes determining the economic impact of wildlife damage management actions, determining value of natural resources, examining the economic efficiency of WS activities, and valuing wildlife caused damage, with an emphasis on the use of benefit-cost analysis and econometrics. Dr. Shwiff also hold affiliate faculty status at Colorado State University and Texas A&M University - Commerce.

NWRC Research Project: Economic Research or Human-Wildlife Conflicts: Methods and Applications

Current Research

Estimating the impact of bird damage to specialty fruit crops, economic evaluation of anti-microbial resistance, valuation methods for preventing bird strikes at airports, benefit-cost analysis of oral-rabies vaccination.
