<1972 Webber IBP Plot Data Barrow Metadata.txt> This file contains meta-data for file <1972 Webber IBP Plot Data Barrow.txt>. Contains data collected on species and land cover and abundance from Webber's IBP plots in 1972 at Barrow, Alaska. GENERAL INFORMATION PI/DATA CONTACT= Webber, Patrick J (MSU)/ Tweedie, Craig E FUNDING SOURCE AWARD # = NSF OPP 9906692 DATA COVERAGE = START: 19720701; STOP: 19720831 UTC PLATFORM/SITE = Barrow, Alaska (71o19'N 156o37'W); INSTRUMENT = Tape measure and 1m2 sampling quadrat. DATA VERSION = 1.0 (12 December 2001), PRELIMINARY [likely to contain errors] CONTACT INFORMATION Craig E. Tweedie 100 North Kedzie Hall Michigan State University East Lansing, MI 48824-1031 Voice: 517 355-1285 Fax: 517 432-2150 Email: tweedie@msu.edu DATA COLLECTION Most plots consisted of 10 1m2 contiguous sub-plots. Some plots consisted of 1m2 arranged in a 10m2 area. For each sub-plot, the presence of all land cover types and all vascular, bryophyte and lichen species were recorded. In 10cm by 1m strips along each sub-plot, the cover of all land cover and plant types listed above was estimated. Some species were lumped if investigators were unsure of their taxonomy e.g. Draba spp. The following texts have been used to standardize nomenclature between 1972 sampling of these plots and sampling in 1999. Vascular Plants Hulten, E. 1968. Flora of Alaska and Neighboring Territories A Manual of the Vascular Plants. Stand University Press. Stanford, California pp. 1008. Lichens Esslinger, T.L. and R.S.

META-DATA FORMAT The following prefixes have been used to designate data type. str - indicates string (text) data dtm - indicates date time data num - indicates numeric data mem - indicates memo data FIELD DESCRIPTIONS for <1972 Webber IBP Plot Data Barrow.txt> strPlotId - Plot identification number strSubPlot - Sub-plot number. strSpp - Species/land cover code strStatus - Status of species/land cover L=Live, G=Ground, O=Other numCover - Cover in a 10cm x 1m strip in sub-plot numPresence - Indicates where species/land cover type is present in sub-plot. memComments - Lists additional comments for record entry. NOTE Patrick Webber, Sue Vetter and John Batty collected 1972 Data. Craig Tweedie performed data entry, quality checking and management. The strStatus class 'O' refers to species and land cover classes measured at the whole sub-plot level only.
