  1. Economic Impact of Cogongrass on Private, Non-industrial Forest Owners in Florida NandkumarDivate Agribusiness Dr. Michael Thomas Dr. Moses Kairo Dr. David Harding Dr. Kome Onokpise

  2. Introduction • Native to southeast Asia • Infests nearly 500 million acres worldwide • Found on every continent • Except Antarctica • Tropical and subtropical areas, limited spread to northern temperate regions • Considered to be one of the worst weeds

  3. Introduction to U.S. • First appearance • Grand Bay, Alabama • Escape from crate packing in 1912 • Intentional introduction • Mississippi as a possible forage in 1921 • Florida introduction 1930s and 1940s • However, little economic (forage) benefit

  4. Worldwide Distribution The general distribution of Imperata cylindrica throughout the world, depicted byareas of white. (Based on information fromHolm et al., 1997.)

  5. Cogongrass infestation in the southeastern United States Points of introduction

  6. Statement of Problem

  7. Objectives • Develop an instrument to survey owners of private, non-industrial forestland in Florida and conduct a statewide sample of private, non-industrial forest owners in Florida. • Use the sample results to document the direct impact of cogongrass on; • - lost forest inventory and reduced forest regeneration and productivity, • - and the direct economic impact of control efforts. • Apply these estimates of direct economic impact to an input/output economic model and extrapolate the indirect and induced effects of these losses to the economy at large.

  8. Methodology • A mail survey was designed and sent to 2800 forest owners • It asked forest owners about their knowledge of the spread, impact, and control techniques of cogongrass. • The instrument has four sections.

  9. Survey Instrument

  10. Methodology • Economic impact of cogongrass will be estimated with input/output (IO) • IO analysis tracks direct, indirect and induced economic effects from • lost forest productivity and • expenditures use to control cogongrass. • Results are reported regional and statewide • Extrapolate the indirect and induced effects to the economy at large.

  11. Data • Source for List of Private non industrial forest owners • Institute of Food and Agricultural Sciences, School of forest research and Conservation, University of Florida • 2832 woodland owners in Florida. Targeted Survey Population

  12. Survey Results Source: Survey questionnaire

  13. Reason For Owning Woodland Source: Survey questionnaire

  14. Cost share Program Participation • 57% respondents cost-share program. • 52 % Used in last five years. Source: Survey questionnaire

  15. Relative importance of common weeds found in Woodlands Mean on the index of 1 to 5

  16. Source of information about Cogongrass • 51% respondents are familiar with cogongrass. Source: Survey questionnaire

  17. Cogongrass

  18. Cogongrass control • 78% Tried to control • Average cost of control $81.56 per acre. • Major chemical – Roundup (83%). Source: Survey questionnaire

  19. Demographic responses

  20. Private non-industrial forest owners area distribution in Florida. Source: Florida division of forestry’s, forest inventory and analysis factsheet (2007).

  21. Cost of control model • Regional cost of control (RCi) can be calculated as follows RCi = ƒ (Ii, Ai, Pi, Ci) (1) Where: Ii = Cogongrass infestation rate for region i. Ai = number of acres of woodland owned by private non- industrial individuals in the region i. Pi = proportion of woodland owners trying to control cogongrass in region i. Ci = average cogongrass control cost for region i. (For region i, i = northeastern, northwestern, central & south)

  22. Input for IMPLAN analysis

  23. IMPLAN analysis • State wide average Impact $14,933,490. Source: IMPLAN analysis results

  24. Detailed IMPLAN analysis Source: IMPLAN analysis results

  25. CONCLUSION • Cogongrass was ranked by Private Non-industrial Forest Owners as the most common forest weed across the state of Florida. • Private Non-industrial Forest Owners are more willing to control Cogongrass using Chemical control rather than Mechanical control. • With Cogongrass’s continued spread, it will likely generate more economic losses to the woodland industry.
