  1. Water Quality of Barred Owl Branch Nicholas Notaro ,Patrick Robbins, Jordyn Reese, Caroline Marr Caleb Riley

  2. In 2010 the Barred Owl Branch study was not conducted. Event

  3. Problem Water Quality effects the animals that live in Barred Owl Branch.

  4. Issue • How has the Stewardship of Harford Glen impacted its environment?

  5. Research Question • To what extent has the water quality of Barred Owl Branch changed compared to prior data collection?

  6. Hypothesis • Water quality will slightly improve because of establishment of new vegetation • Habitat will have improved from last data collection

  7. Prior data • The Barred Owl Branch study started in 2007 and continued through 2009 • 2007 Northern White Pines were clear cut • Stream was slowly increasing health from 2007 to 2009

  8. Data Collection Tools • Vernier Lab-quest • Kick seine • Tally Sheets • Ice cube trays • GPS • Chemical Kit

  9. Chemical Tests • Phosphates • Temperature • pH

  10. pH Data 2011 pH Level GPS Points

  11. pH Averages pH determines how acidic or base a substance is • 2008: 6.5 • 2009: 7.31 • 2011: 7.19 Over the three year period the results have stayed in the neutral range

  12. Temperature In Celsius GPS Points

  13. Temperature Averages Temperature affects the dissolved oxygen the stream can hold • 2008: 25.00°C • 2009: 16.45°C • 2011: 21.71°C Runoff and canopy cover can affect temperature readings

  14. Phosphate Levels GPS Points

  15. Phosphate Averages Phosphate is a nutrient that encourages plant growth • 2008: 3 ppm • 2009: 1 ppm • 2011: 1 ppm Phosphate has stayed in the healthy range, but it still has room to improve

  16. Habitat Assessment • The Habitat Assessment tests the: • Water Color • Bank Erosion • Stream bank Vegetation • Stream Cover • Water Odor • Stream Bottom • Flow Level • Habitat Variety

  17. Habitat Assessment Comparison • Habitat Assessment is a test that measures the health of the habitat. • 2008: 27.1 • 2009: 25.5 • 2011: 25 • The Habitat Assessment Scores for the past three years have been decreasing slowly.

  18. Species Quantity of Macros

  19. Sensitivity at the 2011 way points Quantity of Macros GPS Points

  20. Index Score GPS Points

  21. Biotic Index Map

  22. Tolerance Comparison Quantity of Macros Year

  23. Biotic Index Score Year

  24. Conclusion • Quality of the water has increased since 2007 • Habitat score of Barred Owl Branch is slowly decreasing • Biotic Index has improved over the four years of collection

  25. Inferences • Water quality improved due to newly established vegetation filtering runoff • More runoff in watershed caused by more impervious surfaces • Biotic Index will continue to steadily improve

  26. Action Plan • Continue monitoring Barred Owl Branch • Observe whether buffer zone is in place

  27. Acknowledgements • Ms. Murray • Mr. Cromwell • Juliane Caughron • Mr. Pritchard • Mr. Burley • The rest of the staff at Harford Glen
