Comments: <DIV STYLE="text-align:Left;"><DIV><DIV><P><SPAN><SPAN>The predicted distribution of suitable habitat of nine indicator taxa for Vulnerable Marine Ecosystems (VMEs), and associated model uncertainty layers, were sourced from Anderson et al. (2016b). VME indicator taxa modelled included: Four species of reef forming Scleractinia (stony corals) (Enallopsammia rostrata, Madrepora oculata, Solenosmilia variabilis, Goniocorella dumosa); Demospongiae and Hexactinellida (sponges); Pennatulacea (sea pens); Antipatharia (black corals); and Stylasteridae (hydrocorals). These taxa are a sub-set of the VME indicator taxa identified by Parker et al. (2009) for the South Pacific Ocean. </SPAN></SPAN></P><P><SPAN><SPAN>Location data of VME indicator taxa collated from multiple databases (New Zealand and Australian museum records, fisheries research databases, and online biodiversity databases, with additional records for the Louisville Seamount Chain from a 2014 survey (Clark, 2015)) were combined with relevant environmental predictor variables to produce habitat suitability models using two machine-learning model approaches, MaxEnt (Phillips et al. 2006) and Boosted Regression Trees (BRT) (Elith et al. 2006) which were combined into ensemble models. Predictions of habitat suitability were then made for each 1 km grid cell of the modelled area (New Zealand TS and EEZ in water depths 300-3000 m). This process was repeated 200 times for BRT, 100 times for MaxEnt allowing for mean habitat suitability estimates, as well as coefficient of variation (CV) to be produced for each grid cell in the model extent. Figure 3-2 shows an example of the habitat suitability prediction for the stony coral Solenosmilia variabilis. The ensemble models had a range of model fits (BRT AUC of evaluation data: 0.82 – 0.94; MaxENT AUC of evaluation data: 0.78 - 91), but all results provided a robust estimate of the distribution of habitat suitability for these taxa, and therefore their likely distribution, given the available input data (Anderson et al. 2016). </SPAN></SPAN></P><P><SPAN><SPAN>Raster files: Order Antipatharia (cob_cmb); Family Stylasteridae (cor_cmb); Class Demospongiae (dem_cmb); Enallopsammia rostrata (ero_cmb); Goniocorella dumosa (gdu_cmb); Class Hexactinellida (hex_cmb); Madrepora oculate (moc_cmb); Order Pennatulacea (ptu_cmb); Order Alcyonacea (soc_cmb); Solenosmilia variabilis (sva_cmb): VME probability occurrence from ensemble models (scale = 0-1) within the NZ EEZ. </SPAN></SPAN></P><P><SPAN><SPAN>cob_cv; cor_cv… etc… sva_cv: Associated uncertainty layers (measured as the coefficient of variation, CV) for the VME distribution data from ensemble models within the NZ EEZ.
