description: Variables<br><br>Census - week number the data was collected.<br>Calendar date - date data was collected.<br>Campus - university from where data was collected.<br>Group_ID - identification tag of group that collected the data.<br>Lat - latitude approximated using Google Maps.<br>Long - longitude approximated using Google Maps.<br>Elevation - approximated elevation.<br>Rep - data collection number.<br><br>abundance.native.plants - number of native plants<br>abundance.exotic.plants - number of exotic plants<br>total.number.flowers(quadrats) - flower abundance measured by quadrats<br><br>abundance.woody.plants - number of woody plants<br>canopy.cover - approximated percentage sky is covered by canopy<br>ground.cover - approximated percentage ground is covered by vegetation<br>total.flower.numbers(transect) - flower abundance measured by transects<br><br>abundance.vertebrate - number of vertebrates<br>vertebrate.species - number of species of vertebrates<br>abundance.human - number of humans<br><br>abundance.invertebrates.pantraps - number of invertebrates measured by pantraps<br>abundance.invertebrates.sweep - number of invertebrates measured by sweep nets<br><br>Methods:<br>Methods<br><br>Data was collected across four observers and later compiled into a single digital document.<br>Data collected approximately from 15:00 to 17:00 on October 3, 2016 at the York University Keele Reservoir. Conditions were cloudy, mild temperatures.<br><br>Two transects were used to encompass a 50m distance.<br>25 quadrats were placed in each habitat, distanced apart by 2 meters from the last, while also alternating left and right of the transect.<br><br>A measuring tape was used to approximate distance more accurately at times.<br>Woody plant abundance and other similar data were collected every 2 meters along the transect. They were approximated values.<br><br>In terms of measuring abundance of vertebrates, etc., the observer walked counter-clockwise around each habitat for 15 minutes.<br>The transect aided in visualizing the 50m observation range.<br>Any vertebrate directly above observer were not counted.<br>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.<br><br>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).<br>The pan traps were distanced along the transect, 3 meters apart from the last.<br>10 sweep nets traveled the transect distance to capture invertebrates. 5 sweep nets on each side of the transect.<br><br>Tools:<br>1 Quadrat<br>2 Transects<br>1 Measuring tape<br>1 Jug of soap water<br>2 Sweep nets<br>12 Pan traps<br><br>Hypothesis:<br>The grasslands will demonstrate a greater diversity of life, in terms of abundances, vegetation, and flowers.<br><br>Predictions:<br>1. There will be greater canopy coverage in the grasslands than in the disturbed area<br>2. The disturbed area will have a reduced invertebrate/vertebrate abundance<br>3. There will be more humans in the disturbed area.<br>
