Numerical factors |
Tree height (cm) |
Average height of trees within 5
m × 5 m plots. |
|
Perch height (cm) |
Vertical elevation of arboreal habitat utilized by
lizard, measured from ground level within 5 m × 5 m
plots. |
|
Rock height (cm) |
Average height of all rocks within 5 m × 5 m
plots. |
|
Rock size (cm) |
Average size of all rocks within 5 m × 5 m
plots. |
|
Distance from nearest water (m) |
Minimum horizontal distance from
plot to water source (including springs, rivers, and other water bodies,
without snow). |
|
Distance from nearest road (m) |
Horizontal distance from plot to
nearest road (including transporting, farming, or
grazing). |
|
Light intensity (Lux) |
Light intensity at capture point or centroid
of plots. |
Classified factors |
Vegetation type |
Main vegetation types were
determined according to the vegetation composition of each plot and were
divided into four types: Herb, Shrub and herb, Forest and herb, Forest
shrub and herb. |
|
Vegetation density |
Quantity of trees in plot with three categories:
lower (< 1 m), middle (2 - 7 m), and upper (> 8
m). |
|
Vegetation coverage |
Proportion of upper canopy coverage relative to
ground surface in plot with three categories: lower (< 20%),
middle (20% - 60%), and upper (> 60%). |
|
Substrate status |
Looseness of substrate in plot with three
categories: loose (soil), general (soil-macadam mix), firm (macadam)
(contains more than 50% of substance). |
