Vegetation of Guyra 1:100,000 VISID_561

Alternative title(s)

guyra_rbg_VISmap_561

Abstract

The remnant natural vegetation (excluding native grasslands) of the Guyra 1: 100 000 map sheet area was sampled by way of 312 20 m � 20 m plots in which all vascular species were recorded using a modified Braun-Blanquet abundance rating. Sampling was stratified to cover the environmental factors of substrate, topographic position and altitude. Floristic analyses used the Kulczynski coefficient of dissimilarity in an agglomerative hierarchical cluster analysis and multidimensional scaling ordinations. Twenty-one plant communities were selected from the cluster analysis. The contribution of species to these groupings was investigated using a fidelity analysis. Another three communities were distinguished from aerial photographs and field traverse. These 24 plant communities are described and all except riparian vegetation are mapped. Their extent was mapped using aerial photography and ground traverses. The vegetation map was digitised at a scale of 1: 25 000 but has been reduced to 1: 100 000 for this publication. The minimum area mapped is 1 ha.; ; Cunninghamia 6(3): 747-872.; ; VIS ID 561; ; ANZNS0263000190

Lineage

Lineage:; Vegetation sampled in 312 sites, each 20m by 20m, sites grouped using PATN statistical analysis program. Numerically derived floristic groups mapped at 1:25,000 scale from aerial photographs with extensive ground truthing in February 1998. API data transferred to 1:25,000 map sheet films using a transfer scope and then digitised into Environmental-Resource Mapping System (ERMS) GIS. Errors corrected using ERMS prior to conversion to ArcView shapefile using wpo2shp.exe program. Published in Cunninghamia 6(3).; ; Positional accuracy:; Precision: GIS data accurate to 25 metres. Determination: Deductive estimate. Comparison with 1:25,000 layer data indicated good correlation but with errors of the order indicated above in terms of position.; ; Attribute accuracy:; The 'name' field indicates the floristic vegetation classifications included in the mapping. These have been derived from statistical analysis, interpreted from aerial photographs, ground truthed and described by botanists from the Royal Botanic Gardens. Information on structure, weediness and disturbance is also included.; ; Logical consistency:; The GIS package ERMS was used to perofrm a topological consistency check to ensure all polygons are closed, nodes are formed at the intersection of lines, all polygons are labelled once and there are no duplications.; ; Completeness:; The dataset is complete with reference to range and field verification. Area of smallest polygon is 1 Ha. Riparian shrubland (community 23) is restricted to narrow strips along watercourses and is not shown on the maps. Small clumps of isolated trees in land >70% cleared are not delineated, also native grasslands remaining after the removal of woody canopy species are not shown on the map.
