In 2010 the Barred Owl Branch study was not conducted.

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

 How has the Stewardship of Harford Glen impacted its environment?

 To what extent has the water quality of Barred Owl Branch changed compared to prior data collection?

 Water quality will slightly improve because of establishment of new vegetation  Habitat will have improved from last data collection

 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

 Phosphates  Temperature  pH

GPS Points pH Level

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

GPS Points Temperature In Celsius

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

GPS Points Phosphate Levels

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

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

Habitat Assessment is a test that measures the health of the habitat. 2008: : : 25 The Habitat Assessment Scores for the past three years have been decreasing slowly.

Year Biotic Index Score

 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

 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

 Continue monitoring Barred Owl Branch  Observe whether buffer zone is in place
