Devon - Pit 4

Plant species presence/absence from Pit4 on Devon Island Nunavut.The site was on the Truelove Lowland, a 43 km2 polar oasis on Devon Island, Nunavut. Sample plots were located on dry beach ridges and had plant communities dominated by low growing perennials such as Salix arctica, Dryas integrifolia and Carex spp.The rectangular plot (90 x 220 cm) was surveyed in July 2008. The plot was divided into contiguous 10 cm by 10 cm quadrats and species presence in each quadrat was recorded to produce a stem map precise to the nearest 10 cm. Variables PX and PY record the coordinates of the center of each 10cm by 10cm subquadrat. Variable species is a species code drawn from the genus and species names of the vascular plants present.
