ITEX COMMUNITY DATA - WORKSHOP Data from AUDKULUHEIDI and THINGVELLIR sites in Iceland From: Borgthor Magnusson Agricultural Research Institute, Keldnaholt, 112 Reykjavik Iceland. tel: 354-577-1010, fax: 354-577-1020 email: borgthor@rala.is File descriptions: There are two separate EXCEL-files, each containing on separate sheets, a data and a species file from each site. The file names are: IAUDKULU and ITHINGVE At both sites Canopy and Bottom layers were recorded separately, 1 hit in each layer. An ITEX frame 75x75 cm was used, except for Thingvellir in 1995, when a 50x50 cm frame was used. IAUDKULU-file At AUDKULUHEIDI the methods outlined in the ITEX Manual were followed in the sampling of the data, except for REPEAT, which was not recorded consistently. The REPEAT COLUMN has therefore been deleted in the data file. The ITEX experiment at AUDKULUHEIDI was started in 1996 when CONTROL and OTC plots 1-5 were set up, in an area protected from sheep grazing (NOGRAZE) In 1997 CONTROL & OTC plots 6-10 were set up in the protected area (NOGRAZE) Also in 1997, 10 CONTROL plots were set up in the adjacent grazed area (GRAZE). In 2000 all plots were sampled again for the first time. ITHINGVE-site At THINGVELLIR the sampling was limited to recording of species. There CANOPYHT, MICROTOP, WOODY AND REPEAT were not determined. These columns are therefore not included in the file. The experiment at Thingvellir was set up in 1995, CONTROL and OTC plots 1-10. Sampling of the plots was repeated in 1996, 1998 and 2000.
