Data collected approximately from 15:00 to 17:00 on October 3, 2016 at the York University Keele Reservoir. Conditions were cloudy, mild temperatures. Two transects were used to encompass a 50m distance. 25 quadrats were placed in each habitat, distanced apart by 2 meters from the last, while also alternating left and right of the transect. A measuring tape was used to approximate distance more accurately at times. Woody plant abundance and other similar data were collected every 2 meters along the transect. They were approximated values. In terms of measuring abundance of vertebrates, etc., the observer walked counter-clockwise around each habitat for 15 minutes. The transect aided in visualizing the 50m observation range. Any vertebrate directly above observer were not counted. Humans in vehicles were not counted, and humans that made multiple appearances were also not counted. There was no minimum time for a human to be considered in a habitat, just so long as they remained in range for the observer to make note. 6 pan traps were placed of alternating colors (placed at 15:00 at Grasslands, picked up at 16:06, and placed at 16:30 in Disturbance Area, and picked up at 15:30). The pan traps were distanced along the transect, 3 meters apart from the last. 10 sweep nets traveled the transect distance to capture invertebrates. 5 sweep nets on each side of the transect. Tools: 1 Quadrat 2 Transects 1 Measuring tape 1 Jug of soap water 2 Sweep nets 12 Pan traps Hypothesis: The grasslands will demonstrate a greater diversity of life, in terms of abundances, vegetation, and flowers. Predictions: 1. There will be greater canopy coverage in the grasslands than in the disturbed area 2. The disturbed area will have a reduced invertebrate/vertebrate abundance 3. There will be more humans in the disturbed area.
