SITE DATA FIELDS (#marks fields)

#site
TEXT
TREND site identification code: the general location of a set of 5 replicate plots (see ‘plot’)

#plot
TEXT
TREND plot identification number. First 3 letters of property or locality plus 1/2 if >1 set of replicate plots at locality; A-E to signify replicate plot number, e.g. REM1-A = replicate plot A from site 1 in Mount Remarkable NP.

#latitude / longitude
NUMERIC (decimal degrees)
GPS (WGS84), accuracy ± 3 m, taken at SW corner marker.

#altitude_mASL
NUMERIC (m ASL)
Read from GPS at SW corner.

#establishment_date
TEXT in date format
Date plot pegged and surveyed.

#property
TEXT
Name of property plot located within.

#locality
TEXT
Free text brief identifier of general locality for plot.

#location
TEXT
Free text description of more specific location of plot.

#observers
TEXT
Initials/surname of observers at plot establishment.

#photo
TEXT
Photo numbers that match file names. Photo taken from SW corner of plot facing NE, sometimes moved if large bush in the way at corner etc.

#photopoint_disc
TEXT
Number on S.A. Government photopoint tag wired to plot marker (doesn't appear in the plot photos, it's just a plot marker).

#aspect /  aspect_text
NUMERIC (degrees)/ CATEGORICAL
Measured with a standard compass, in degrees, also with text description (e.g. 90º, E). Observer faces downslope to take reading.

RANGE: 0 to 360

CATEGORIES:
"N"", "NNE", "NE", "ENE", "E", "ESE", "SE", "SSE", "S", "SSW", "SW", "WSW", "W", "WNW", "NW", "NNW", "N", where N=north, E=east, S=south, W=west

#slope
NUMERIC (degrees)
Estimated with aid of a digital level measure rested on representative, evenly sloped spot on flat object (e.g. dowel). Estimated accuracy ~±5º

RANGE: 0 to 90

#outcrop
NUMERIC (%)
Visual estimate of percent cover of outcropping rock.

#surface
NUMERIC (%)
Visual estimate of percent cover of surface stones.

#sand
NUMERIC (%)
Percent sand by volume in settled sample.

#NH4
NUMERIC (mg/kg)

#NO3
NUMERIC (mg/kg)

#P
NUMERIC (mg/kg)
Colwell P

#K
NUMERIC (mg/kg)
Colwell K

#conduct
NUMERIC
E.C.(dS/m) [electrical conductivity]

#pH_CaCl2
NUMERIC (0 to 14)

#disturbance_notes
TEXT
Free text description of disturbance evident, e.g. fire scars, tracks. Grazing detected through evaluation of leaf damage, spp. identified visually from scats (i.e. kangaroos), tracks and burrows (e.g. rabbits).

#distance_to_nearest_nonuniform_vegetation:
NUMERIC (m)
Visual estimate taken from the SW corner. Conservative estimate, especially where visibility low. Intended for remote sensing and other applications of data. Could also be used as general indicator of landscape heterogeneity.

#landscape_position_notes
TEXT
Free text description for context describing plot location relative to landscape features nearby (e.g. is it at the base or ridge of a gully?).

#general_notes
TEXT
Free text.

#association
TEXT (structured)
