  1. Assessment of macrophytes and sediment depth accumulation at OX Ranch Heath Korell Jenna Davis Nick Porter Sean Taylor

  2. Outline • Rationale and study area • Methods • Results from data • Recommendations for macrophyte control

  3. Rationale • Severe overgrowth of macrophyte species • Natural Eutrophication • Could lead anoxic conditions • Potential for fish kill

  4. Methods • Sediment Sampling • K-B Corer • Creates a vacuum for the sediment • Analyzed • Biomass • Wet weight • Dry weight • Ash weight

  5. Methods Macrophyte Sampling • Large Macrophyte Sampler • Analyzed • Phosphorous Analysis • Biomass • Wet weight • Dry weight • Ash weight

  6. Types of Macrophytes we gathered Oaks Pondweed Coontail

  7. Milfoil Duckweed

  8. Site 1 core results

  9. Site 2 core results

  10. Site 3 core results

  11. Total phosphorous in pond 3

  12. Biomass

  13. Implications/Recommendations • Raking • Create macrophyte channels for habitat (Olson et. al, 1998) • $495.00 • 5 ft. Wide

  14. Use a Biological Control • Triploid Grass Carp • Herbivore • Cost • 8-9 fish • $10-$20/ fish • Permit to import carp $23.50 • Carp must be certified triploid • Certified free of Asian Tapeworm

  15. Summary • Core lengths and Macrophyte samples were collect • Analysis of core composition and phosphorus • Macrophyte genera and their biomass • Management Implications
