TITLE. Imnavait Creek grid point quadrat measurements: 1989, 1995, and 2001 Plant species composition, canopy structure, and microtopography data. ABSTRACT. Permanent 1-m^2 plots were established beside each of 72 out of the 100 Imnavait Creek grid stakes in 1989. The grid points are spaced 100 meters apart. Plots are numbered according to row and column, beginning with 203 at the northeast corner of the grid. Plot 810 is located at the southwest corner of the grid. Each plot was located within 2 m of the grid stake, but always in the same vegetation type as that associated with the stake. The distance and direction from them were randomly selected, and thus varied from plot to plot. Point quadrat measurements are to be made every 5 years to quantify species composition, canopy structure, and microtopography. The point-quadrat technique used was identical to that described by Auerbach (1992): The point-quadrat method was used for estimating canopy stratification and plant cover. Aluminum point-quadrat frames were 1-m^2 in size, with double-layer filament spaced 10 cm apart to make a 10 x 10 cm grid for a total of 100 sample points per plot. Before sampling, the point-quadrat frame was leveled and plots were permanently marked in the following manner. Aluminum tags were nailed into the ground so that a frame could be repositioned in the same location from year to year; i.e., tags with a hole in the middle were used to define the locations for the point frame legs and four tags with a "X" stamped on them (positioned somewhere inside each of the frame corners) were used to define alignment of the frame by positioning the string crossings over these "X"s. Distances from the frame to a top canopy plant hit and to a surface layer plant hit were measured to the nearest 0.5 cm and recorded. Note that this measurement does not give canopy height from the ground, but from the point quadrat frame. Plant genus and species were also recorded at both hits at each point. CITATIONS.

DATA SET OVERVIEW: This file contains plant species composition, canopy structure, and microtopography data for the point frame data collected at the Imnavait Creek Grid from 1989, 1995, and 2001. The grid is part of the International Tundra Experiment network. The goal of this project is to assess potential changes in tundra plant communities in response to global climate change. This file can be used in conjunction with Pointframe_species file to determine species names from the numeric species code found in this data file.

POINT_ID: point identification number given to each point 2. YEAR: year of data collection (YYYY) 3. PLOT: plot number 4. X_COORDINATE: X coordinate of point frame grid (cm) 5. Y_COORDINATE: Y coordinate of point frame grid (cm) 6. Top_Species: top hit species code 7. Top_Quality: top quality 8. Top_Condition: condition of top hit 9. Top_Woody: location of top hit 10. Bottom_Species: bottom hit species code 11. Bottom_Quality: bottom quality 12. Bottom_Condition: condition of bottom hit 13. Bottom_Woody: location of bottom hit DESCRIPTION OF SELECT VARIABLES: POINT_ID: point identification number given to each unique point *_Species: numeric species code given to the species hits. The file Pointframe_species.csv have the full species name represented by the number. *_Quality: Hit codes are 1 ("bulls eye" hit) and 0 (mediocre hit). A single "hit" was always defined as being both a top-layer hit and bottom- layer hit. *_Condition: Species condition codes are 1 (live), 2 (standing dead), 3 (dead), and 4 (other). Species condition code 4 was used for all non-vegetation hits (e.g., soil, litter, rock, bare). *_Woody: Woody (1) or non-woody (0) conditions were also recorded for each species.

Each plot can contain comments they are included below. 205,no carbig 207,check 89 photo for ERIANG 210,moss wires at A and D indicate no growth since 1990 and A cross tag moved north about 1/4 cm and point 25-85--DACARC is correct--species may have been misidentified in 1989 as DACMAD 304,aulpal present but not abundant 305,no erivag 306,change sphrub to sphwar on 1989 data sheets 307,for Dicranum-up to now and including this plot--what we have called DICSCO may be DICANG (was id'd in this plot in 1989) and abundant liverwork (ANAMIN?) growing in DICELO on hummocks 310,need to look up Nephroma 403,change rubellum to warns.? 1989 point 25-45=ERISCH--should this be carrot? what we base id on? check photo 404,betnan is at edges of plot but in the watertrack (and in the plot) is Betula glandulosa 407,"bletri" collected 606,start seedling catyegory here 607,change 89 data sheets SPHRUB to SPHNEM 706,point 55-55 id'd as dicang in 89 but looks like ??? 708,check whether we need CLASTE or CLAMIT 807,possibly sphrub is SPHWAR based on fact TOMNIT is growing there but stem leaf look like SPHRUB 905,no markers and no standing water--leg depths are to permafrost 910,check 1989 photo for presence of ERIANG which is now quite abundant 1007,some problems on 89 data sheet w/ sphagnum corrections 1008,appears to be physical damage to this plot--tussock is cracked as if walked upon Each plot can contain other species that were found in the plot but were not actually hit.
