Benthic Macroinvertebrate Data from TRCA’s Regional Watershed Monitoring Program, 2013-2019
Dataset provides an overview of the benthic macroinvertebrate communities in lotic systems in TRCA’s jurisdiction for the purposes of biomonitoring and bioassessment.
"[Site Name] A unique tracking id that identifies a distinct site as distinguished by coordinates [Watershed] Name of the watershed each site is located within [Subwatershed] Name of the subwatershed each site is located within [UTM Zone], [UTM Easting], [UTM Northing] The Universal Transverse Mercator (UTM) of site location to the nearest metre [Latitude], [Longitude] The XY coordinates of site location in decimal degree units [Year], [Collection Date] The calendar year and date on which the sample was collected [Phylum] Consistent Phylum name of the taxa [Class] Consistent Class name of the taxa [Order] Consistent Order name of the taxa [Family] Consistent Family name of the taxa [BMI Taxa] Consistent unique name of the taxa at the level the taxa was identified to [Common Name] Consistent common name of the taxa at the Order or Family level [Total Count] Number of Individuals in each BMI taxa [Habitat Sampled] The micro-habitat unit targeted for sampling. Based on The Ontario Benthos Biomonitoring Network (OBBN) standard sampling protocols, targeted habits include riffles and pools: Riffle areas of fast, turbulent water, often characterized by gravel/cobble substrates, and Pool areas of slow, deeper than average water associated with deposition or the impoundment of water from a flow obstruction. [Subsample Number] The sequence of transect subsamples were collected, ranged from 1-3. This number is used to differentiate the two riffles transect subsamples. [Collection Method] The sampling device with which the sample was collected. [Lab Method] The processing method with which the sample was sorted in the laboratory. "
