Each site was represented by full floristic vegetation plot that forms part of the OEH Vegetation Information System (VIS) database. All sites were assigned a Plant Community Type (PCT) as part of the new East Coast Vegetation Classification (ECVC).  Monaro is represented by the RCP group R4.42E (Monaro -Central-Tablelands frost hollow grassy woodland), which is historically linked to SCIVI Vegetation Types m31/p220 and UMC types m31/u118). Conversely, the Werriwa is represented by the RCP group R4.141 (Werriwa frost-hollow grassy woodland) which is linked to the SCIVI Vegetation Type p24. As part of the development of the ECVC, the floristic data of individual sites were checked and vetted, and sites strongly influenced by disturbance removed.  Additional sites that are assumed to represent the CEEC\u2019s were also added. These sites came from surveys conducted by OEH threatened species ecologists and other experts that were not included in the ECVC. They include most, but not all sites identified by the Scientific Committee as representative of the TEC . \r\n3.\tCEEC presence modelling\r\nA presence-absence (PA) distribution modelling approach was used to create an initial indicative (potential) distribution map of the CEEC\u2019s. A total of 84 sites were included in the models as presence sites for Monaro and 59 for Werriwa (Fig 1). While these sets contain an adequate spread of sites over the presumed range of the TECs, the models are strongly influenced by the number of absence sites ascribed to PCTs that are not related to R4.42E and R4.141.\r\nThe modelling methodology is described in detail in OEH (2016). The Random Forest (RF) technique was used to predict the potential extent of the communities in terms of their probability of occurrence across the South Eastern Highlands and South East Corner Bioregions. \r\nAll models were run with 10-fold cross validation, using held-out data to calculate performance measures which are used to select optimum model parameters and final model fit. Statistics were derived from a confusion matrix, calculating overall accuracy, user and producer accuracies and standard deviations.\r\nResponse curves for each predictor to determine if the effect of the variable on the response makes ecological sense reran multiple iterations of models to look at the effects of sequentially removing predictors in an attempt to generate a more parsimonious model. The models show a continuous probability of occurrence surface which varies between 0 and 1. \r\nA sensitivity = specificity threshold, which balances the risk of making commission and omission errors, was used to determine the area of the core candidate CEEC. This was subject of further investigation by API. The sensitivity = specificity threshold is 0.4 for the Combined model, 0.48 for the Monaro-only model and 0.33 for the Werriwa only model.\r\n4.\tPattern derivation\r\nThe binary core modelled extent was pulled into a net of existing vegetation linework for finer scale manual interrogation and attribution. A multi-resolution segmentation algorithm was used to create image objects with low internal variation. Image objects represent patches of vegetation that can later be classified based on attributes such as crown cover, spectral response, or soil type. The segmentation parameters and scale were derived iteratively based on visual inspection. Vegetation recognised in high spatial resolution imagery (ADS40 \u2013 50cm) were used as a reference point. This process provided the line work for subsequent PCT attribution.\r\n5.\tFine scale mapping and Aerial Photo Interpretation\r\nHigh resolution expert aerial photographic interpretation (API) was then used to assess CEEC spatial presence within the core extent.  Some locally adjacent areas where the community was found to occur were also included.  This process referenced 50cm 3-D ADS40/80 imagery. Polygon attribution utilised two software packages, ArcGIS Dektop 10.7 and DAT/EM Summit Evolution \u2013 Lite Edition (a photogrammetric package enabling 3D stereo viewing of ADS40 imagery).\r\n6.\tExtension of CEEC presence to adjacent candidate native grasslands\r\nAfter rigorous 3-D API, the spatial extent of the CEEC was extended by default into adjacent candidate native grassland as attributed by2-D 50cm ads imagery. This extension was constrained by lot boundaries. Please the technical notes for further details on the manual stage decision logic.\r\n", "maintainer": null, "maintainer_email": null, "metadata_created": "2020-07-02T04:37:53.034059", "metadata_modified": "2025-10-23T01:07:02.626273", "name": "ceec-monaro-and-werriwa-tablelands-cool-temperate-grassy-woodlands-v1-4", "notes": "The Monaro and Werriwa Tablelands Cool Temperate Grassy Woodlands (respectively Monaro and Werriwa) have been nominated by the NSW Scientific Advisory Committee as Critically Endangered Ecological Communities (NSW Threatened Species Scientific Committee (2019).
