Underwater visual census (UVC) at inner and outer reef sites within both recreational and sanctuary zones (SZ) were undertaken from North West Cape SZ to the Turtle SZ at the southern end of NMP. In total, 132 lobsters from five species were counted from 265 transects and 18 separate locations (58 sites) along the entire coast of the NMP.

Sub-tidal surveys on snorkel and SCUBA were used for octopus surveys and were done simultaneously with lobster surveys. In addition to these, inter-tidal surveys were conducted in December 2008 providing total coverage of octopus habitat across a reef profile. In total, just 28 octopus from a single species (Octopus cyanea) were counted from 410 transects (265 subtidal and 145 inter-tidal) and 59 separate sites along the entire coast of the NMP. The specific objectives of this project were: 1) A report on stock status for targeted invertebrate species along the length of Ningaloo Marine Park including octopus and lobster. 2) A characterization of habitats associated with high numbers of targeted species. 3) A comparison of stock abundance in relation to differing levels of visitor access.

In addition, a further 6 related questions had been put forward as important to the management of the NMP: 1) What is the species diversity of invertebrates at representative habitats in the NMP? 2) What is the relative abundance of these species and how do they compare with the 'natural' abundance of these species on comparable reefs? 3) How does the abundance of these species change over a gradient of historical and human pressure? 4) Are current fishing regulations appropriate? 5) What should management targets be? 6) What species should be monitored regarding these species?

The crayfish records in this dataset are fom three main sources. 1) Records were submitted to the Biological Records Centre as the result of a project funded by English Nature (formerly the Nature Conservancy Council) and the Environment Agency (formerly the National Rivers authority). The project was carried out at Nottingham University by Dr David Holdich, David Rogers and Ian Reeve. This dataset includes field records and records derived from published sources. They cover the period 1900 to 1996. The records have been verified by Holdich and his co-workers and subject to routine validation by BRC. 2) Records were collated from the Enviroment Agency by Peter Sibley in 2003. Records were extracted from EA files that had been collected during crayfish surveys by Agency staff, and from other sources. Records were also extracted from the EA macroinvertebrate database of samples collected by Agency staff in the field. This dataset covers the period 1900 to 2003. Records were verified by Agency staff and have been subject to routine validation by BRC. 3) A small additional dataset of Environment Agency records from the EA Northumbrian Region has been added. Uploaded 14th July 2004.

Records were compiled from a number of events primarily led by staff of the Vermont Institute of Natural Science (VINS) and White River Partnership (WRP). In 2005, VINS environmental citizenship program director Jenna Guarino worked with Vermont Department of Environmental Conservation (VTDEC) aquatic biologist Jim Kellogg and 6 local ‘Teen River Stewards’ to conduct the first sampling of portions of the White River mainstem and some of its major tributaries. After finding nearly 85% of the trapped crayfish were non-native rusty crayfish (Faxonius rusticus, formerly Orconectes rusticus), primarily from the mainstem of the White (rather than tributaries) the teen stewards worked with VINS, WRP and VTDEC staff to conduct an educational outreach and training at the White River National Fish Hatchery in Bethel.

In 2010 VTDEC aquatic biologists partnered with watershed education consultant Jenna Guarino to offer a workshop to White River watershed teachers who wanted to help track the spread of rusty crayfish. Six teachers participated in the workshop and implemented at least one day of trapping with their students. A first known occurrence of Bigwater crayfish (Cambarus robustus) in the White River watershed was documented during the workshop (several more occurrences have been documented since then). Quality-assured data collected by schools was shared with state biologist Jim Kellogg, who built a Vermont crayfish species database and distribution map.

They are a critically endangered species - http://www.dpi.nsw.gov.au/fisheries/species-protection/conservation/what-current/critically/fitzroy-falls-spiny-crayfish. The methods used to create the predicted current distribution of Fitzroy Falls spiny crayfish are described fully in: NSW Department of Primary Industries (2015), NSW Fish Community Status 2015 - Final Report. Purpose The dataset has a number of primary functions including but not limited to; * spatially representing the status of fish communities at river reach scale across NSW * providing additional support to strategic planning frameworks to ensure they effectively integrate biodiversity considerations into planning and decision making processes Dataset History This data and its metadata statement were supplied to the Bioregional Assessment Programme by a third party and are represented here as originally supplied. All available records of the species were collated and assessed for accuracy. For current distribution, only records after 1 January 1994 were used. Within the framework of the Australian Hydrological Geospatial Fabric V2 surface hydrology network, the records were associated with attributes from the National Environmental Stream Attributes Database and River Styles® geomorphology. The Australian Hydrological Geospatial Fabric V2 surface hydrology network (Geofabric) is a fully connected and directed stream network based a 9 second DEM. It allocates a unique stream segment number to each river reach in Australia. The Environmental Attributes Database is a set of lookup tables supplying attributes describing the natural and anthropogenic characteristics of the stream and catchment environment that was developed by the Australian National University (ANU) in 2011 and updated in 2012. The data is supplied as part of the supplementary Geofabric products which is associated with the 9 second DEM derived streams and the National Catchment Boundaries based on 250k scale stream network. 30 Stream variables were assessed for the modelling. River Styles® provides a high resolution categorical classification of river character within a nested hierarchy of criteria based on valley setting, channel planform, geomorphic units, and bed material. The NSW Office of Water compiled a spatial dataset of River Styles® classifications for a large number of the waterways of NSW. From 65 River Style® categories we generated two new fields representing Planform (34 categories) and Substratum (8 categories) for each stream segment. River Style® planform and substratum categories were then assigned to each Geofabric segment. MaxEnt 3.3.3 is a widely used species distribution modelling program that utilises presence records to generate probabilities of occurrence based on a suite of environmental variables quantified across the area of interest. It was used to model the current geographic distribution of each listed threatened freshwater aquatic species or population. We utilised logistic output to plot the predicted distribution of each species. This output equates to a probability that the species will be observed in each river reach, given the environmental conditions that exist there relative to the environmental conditions where the species is known to occur. For this mapping, above 33% probability was considered predicted presence. In addition, predicted separate populations were connected by manual interpretation. The predicted values for each river reach were converted from the Geofabric framework to the higher resolution 2013 NSW Strahler Stream Order Hydroline.
