Assessment of macrophytes and sediment depth accumulation at OX Ranch Heath Korell Jenna Davis Nick Porter Sean Taylor
Outline • Rationale and study area • Methods • Results from data • Recommendations for macrophyte control
Rationale • Severe overgrowth of macrophyte species • Natural Eutrophication • Could lead anoxic conditions • Potential for fish kill
Methods • Sediment Sampling • K-B Corer • Creates a vacuum for the sediment • Analyzed • Biomass • Wet weight • Dry weight • Ash weight
Methods Macrophyte Sampling • Large Macrophyte Sampler • Analyzed • Phosphorous Analysis • Biomass • Wet weight • Dry weight • Ash weight
Types of Macrophytes we gathered Oaks Pondweed Coontail
Milfoil Duckweed
Implications/Recommendations • Raking • Create macrophyte channels for habitat (Olson et. al, 1998) • $495.00 • 5 ft. Wide
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
Summary • Core lengths and Macrophyte samples were collect • Analysis of core composition and phosphorus • Macrophyte genera and their biomass • Management Implications
