  1. Katrina’s Impact on the Green Industry in South Mississippi • Commercial Horticulture • (greenhouse and nursery production and retail) • 84 respondents (out of 800 surveyed) • $9.98 million in reported losses • Reported an estimated $17-19 million loss for the nursery industry • Most losses were crops losses, equipment and structural damage Data collected and summarized by Mississippi Nursery and Landscape Assoc.

  2. Katrina’s Impact on the Green Industry in South Mississippi • Commercial Turf (data summary ongoing) • Many of the 22 courses on the coast are open for limited or full play • Lawn care services have lost market • Reduced market for all sectors of the turf industry (golf, lawn care, ag. sales) • Sample losses: • Lawn care service >$200,000 losses

  3. Data collected be Stewart, Wells, Collins, and Held, October 2005

  4. Will hurricane-related stress tip the scales in favor of borers? Data from Held and Hughes, Feb. 2005

  5. Recovery of Live Oaks following Hurricane Katrina • Julie Dobbs, Ph.D. student • Monitor tree health following three health care regimes • Document the microfauna associated with live oak recovery

  6. Larra bicolor research • New state record published in FL. Entomologist • USGA-funded project for 3 years L. Buss L. Buss

  7. Known distribution of Larra bicolor in coastal MS indicates sites where Larra bicolor have been observed or collected

  8. Earthworms Damage to Home Lawns? “Before the publication of Darwin's account of the activities of earthworms (Darwin 1837, 1881) it was commonly believed that earthworms feed on living plants, and they were widely regarded as plant pests…” K.E. Lee 1985. Earthworms: Their ecology and relationship with soils and land use.

  9. Earthworms Damage to Home Lawns? • Not documented by any of the turfgrass entomology textbooks • Kansas State Horticulture Newsletter no. 9, March 2002 • “April showers not only bring May flowers but also may bring bumps in the lawn. If you have mounds of soil in your lawn that make it hard to mow, nightcrawlers may be the cause.”

  10. First account (Gautier 2004) St Augustine grass lawn Mole cricket damage No mole crickets present Earthworms abundant

  11. Long Beach and Gulfport (2005) • Residents complained of surface mounds • Lawn care technicians report earthworm damage • Four areas sampled for pests and soil characteristics

  12. (Percent of area covered by turf in the 1 m x 1m plot)

  13. Soil characteristics

  14. Soil characteristics

  15. Calcium, water content high in samples with more worms • Earthworms do not prefer strongly acidic soils (pH 6.2- 7.2) • Abundant organic matter at all sites
