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: 27.1 2009: 25.5 2011: 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

Water Chemistry Testing. We have been investigating the “health” of the Ramsey Brook in the following ways: Mapping Imperviousness Surveying Macroinvertebrates.
There are several different physical parameters, or measurable factors, that affect water quality. The first is temperature. In general, the cooler the.
