Experimental Ponds

The 13 experimental ponds are located on the South Campus of the University of British Columbia. Each pond is 23 x 23 m2 with a bottom that slopes gradually from 0 m at the edges to 3 m deep in the center. The ponds were constructed in 1991 and then seeded with plants and invertebrates from Paxton Lake, Texada Island, British Columbia, an 11-ha lake that is the source of limnetic and benthic stickleback species used in pond experiment. The ponds are lined with polyethylene overlaid with 0.25 m of sand, and are bordered with limestone extracted from surface mines on Texada Island. Apart from their construction, initialization, and use in prior experiments, the ponds are unmanipulated environments.
