North Temperate Lakes LTER: Sparkling Lake Macrophytes 2001 - 2010
Macrophyte cover in Sparkling Lake sampled in late July from 2001 to 2010 from the waterline to a depth of 4 meters.
Macrophyte cover in Sparkling Lake was assessed in the third or fourth week of July from 2002-2004 and from 2007-2010. Eight transects were selected to correspond to trap survey sites for rusty crayfish and represent the range of macrophyte communities in the lake. These transects stretched from the waterline to a depth of 4 meters, running perpendicular to shore. Circular quadrats (1m2) were placed along each transect at 1 m longitudinal intervals, and observers using SCUBA estimated visually the percent cover of each macrophyte species within the quadrat. The sum of percent cover of all species within a quadrat does not necessarily add to 100; rather, this sum reflects the percentage of bottom substrate covered by macrophytes.
