Hornsby Local Government Area Remnant Trees, 2008. VIS_ID 4472

Stands of remnant trees are important for conservation of biodiversity in the Urban District of Hornsby Shire. Particularly important are the stands of Blue Gum Shale Forest, Blue Gum Diatreme Forest and Turpentine-Ironbark Forest trees, because even in the absence of a native understorey, these are recognised as critically endangered or endangered communities under the NSW legislation (but not under the Commonwealth legislation).

Two separate studies of remnant trees were carried out - the urban district and the southern rural district.

For the urban district, a total of 569 stands of remnant trees were mapped, ranging in size up to about 2.9 ha, although predominantly less than 1 ha. The total area of the stands was about 130 ha in March 2007. The stands are remnants of 15 different native vegetation communities. Three of the communities are listed as critically endangered under either Commonwealth or NSW legislation; four others are listed as endangered; one is considered significant at regional level (Sydney region); and two are considered locally significant (Hornsby Shire).

For the southern rural district, A total of 866 stands of remnant trees were mapped, ranging in size up to about 6 ha. The total area of the stands was 408.8 ha in March 2007. The stands are remnants of 14 different native vegetation communities. Two of the communities are listed as critically endangered under Commonwealth legislation; three others are listed as endangered under NSW legislation; two others are considered significant at regional level around Sydney; and two others are considered locally significant in Hornsby Shire. Two of the communities (Shale Gravel Transition Forest and Angophora-Red Mahogany Forest) appear to be represented in Hornsby Shire only by remnant trees; these communities have not been recorded in the bushland areas of Hornsby Shire.

The Native Vegetation of the Sydney Metropolitan Area - Version 3.1 (OEH, 2016) VIS_ID 4489

This layer contains digital mapping of the native vegetation communities of the Sydney Metropolitan area. Vegetation communities have been derived from the analysis of 2200 floristic sites collated for the study area. Identified vegetation communities have been related to currently listed threatened ecological communities listed under the NSW TSC Act, 1995 and the Commonwealth EPBC Act, 1999. Native vegetation communities have been mapped using a combination of detailed image interpretation, relationships between sample sites and abiotic environmental variables. The derived digital data layer includes fields that describe the vegetation community, interpreted dominant species and understorey characteristics, interpretation confidence, disturbance type and severity, NSW vegetation formation and classes and related NSW Plant Community Types. These are described in detail in technical reports OEH (2016) The Native Vegetation of the Sydney Metropolitan Area. Volume 1: Technical Report. Version 3.0. Office of Environment and Heritage Sydney. OEH (2016) The Native Vegetation of the Sydney Metropolitan Area. Volume 2: Vegetation Community Profiles. Version 3.0. NSW Office of Environment and Heritage, Sydney.
Version 3.0 of the Native Vegetation of the Sydney Metropolitan Area updates the Plant Community Type and Biometric Vegetation Type of each map unit. 

Version 3.0 replaced version 2.0 (VIS_ID 3817) and created a seamless alignment between the GIS layer and the Plant Community and Biometric Vegetation Types in the Biodiversity Assessment Method tool. These were the only significant updates from version 2.0.

Version 3.1 is a minor update. Two new attribute fields were added - PCTID and PCTName. These fields align with the Bionet Vegetation map data standard v1.0(https://www.environment.nsw.gov.au/research-and-publications/publications-search/bionet-vegetation-map-data-standard-version-1). PCTID was populated by the v3.0 attribute field, PCT_code. PCTName was populated by extracting the corresponding PCT common name from the Bionet Vegetation Classification web service (https://data.bionet.nsw.gov.au/). No other changes were made to the vegetation map.

Degree of River Regulation (Spatial Dataset)

This data summarises the results of a spatial analysis to identify significant tributary junctions in rivers, across the NSW Murray-Darling Basin, where inflows from unregulated or less regulated tributaries join heavily regulated rivers. Tributary junctions were characterized in terms of the relative change in the ‘Degree of Regulation’ (DoR) at individual tributary junctions. DoR was calculated as the ratio of the storage capacity of all upstream reservoirs relative to the mean annual runoff. Furthermore, This spatial analysis identifies potential tributary hotspots across the NSW Murray-Darling Basin (MBD).

Rivers often experience major discontinuities in ecological function due to dams, whereby the timing and volume of flow and water chemistry can be significantly altered from upstream to downstream of the dam, impacting ecosystem productivity and aquatic food webs. Tributary inflows from such unregulated catchments can play an important role in mitigating changes in water chemistry below large dams, thereby overcoming the so-called serial discontinuity effect, which describes the impacts of large dams on longitudinal gradients in water chemistry. Because tributary inflows can be rich in nutrients and dissolved carbon, they can lead to ‘priming’ effects, in which biogeochemical processes and ecosystem productivity are enhanced below confluences with more heavily regulated rivers. Yet, there have been few attempts to identify potential priority tributaries that may play a larger role in driving biochemistry and ecosystem function below dams. This spatial analysis identifies significant tributary junctions in rivers, across the NSW Murray-Darling Basin, where inflows from unregulated or less regulated tributaries join heavily regulated rivers.

Spatial Layer of HEVAE Vegetation Groundwater Dependent Ecosystems Value in NSW

NSW DoI Water has adopted the Guidelines for Identifying High Ecological Value Aquatic Ecosystems (HEVAE) framework developed by the Australian Commonwealth Government. In the current assessment for NSW, the HEVAE consists of four key criteria which include diversity, distinctiveness, naturalness and vital habitat. Therefore, the HEVAE vegetation GDE value layer is a combination of four individual criterion layers. The final or overall HEVAE score was determined for vegetation PCT polygons which has a high probability of being groundwater dependent. This was calculated by adding together the final scores for each criterion (Naturalness, Diversity, Distinctiveness and Vital Habitat). This score was then standardised by dividing by the maximum combined HEVAE score for a whole catchment’s vegetation GDE polygons to provide an even spread of score outcomes between 0 (lowest) and 1 (highest). For ease of data modelling and management, the dataset was divided into the following catchment management areas; Border Rivers-Gwydir, Central Tablelands, Central West, Hawkesbury-Nepean, Hunter-Central Rivers, Lachlan, Lower Murray Darling, Murray, Murrumbidgee, Namoi, Northern Rivers, Southern Rivers, Southern Tablelands, Sydney Metro and Western Division (MDB and far west subdivided further into the IBRA Sub regions).

Vegetation, Northern Hawkesbury LGA (Draft) 2008. VIS_ID 4167

Vegetation mapping of the northern part of Hawkesbury LGA. For more information see DECC (2008). This report describes the outcomes of a joint project between the Hawkesbury-Nepean Catchment Management Authority (HNCMA) and the NSW Department of Environment and Climate Change (DECC) to deliver a consistent and seamless vegetation map for the northern Hawkesbury Local Government Area (LGA). The project has been designed to provide the HNCMA and DECC with baseline data on vegetation communities to facilitate the implementation and reporting of biodiversity targets and objectives set out in the Hawkesbury-Nepean Catchment Management Plan. The major driver for this project was recognition that the study area was without consistent classification and mapping data that covered private lands and crown land tenures between the mapping available for the Cumberland Plain and the Yengo, Wollemi and Parr reserve systems. The study area covers around 28,000 hectares of land around the Hornsby Plateau in north-western Sydney. It encompasses the interface between the extensive shale deposits of the Cumberland Plain and the dissected sandstone plateaux. It is a zone that is undergoing rapid transformation in land use with rural holdings being transformed to hobby farms and urban subdivision expanding into rural-urban zones. VIS_ID 4167

Water Modelling-Modelled Data-Long-term average annual extraction limit (LTAAEL)-Macquarie

Long-term average annual extraction limit (LTAAEL) is a regulatory limit set on annual water extractions from a river system. It ensures that average extractions over the long term are sustainable, and thus help prevent environmental degradation.

In NSW these limits are defined by water sharing plans (WSPs). Every WSP outlines how the water in a river system will be shared over a 10-year period. They also define:

• how LTAAEL compliance is to be assessed for each river system

• what conditions will trigger noncompliance action

• what compliance action can be taken.

The Natural Resources Commission regularly reviews all WSPs to ensure extractions from each river system are within the limits set, and the Murray-Darling Basin Authority reviews sustainable diversion limit (SDL) compliance each year.

To assess compliance, we model LTAAEL using a model that has been configured to represent the development and management rules defined by a system WSP (this refers to as LTAAEL model). We then compare this modelled LTAAEL with the modelled under current conditions long-term average annual extractions (LTAAEs) (which are usually those modelled by the annual permitted take, or APT, model). Although, the LTAAEL includes multiple types of water use, the compliance assessment is based on the total. We do this annually using the best available models, and the outcomes are published on the DPE website.

Where river system’s LTAAE exceed LTAAEL, the system is considered noncompliant. If the noncompliance trigger conditions in the WSP are met, noncompliance action is taken.

The data set provided contains flows at several gauges in each river system, as simulated by the annually extended LTAAEL model. Notwithstanding the model’s inherent limitations, these are a fair representation of those we would expect under WSP operation and development conditions. They can be compared with flows simulated by other key scenario models, such as annual permitted take (APT) model or without development (WOD) model.

Walking count surveys

Twice a year we carry out walking count surveys to give us a picture of walking trends across the local area. The counts take place at around 100 locations from 6am to midnight in fair weather conditions, on a weekday and a day on the weekend in March and October. The survey locations were selected based on the Liveable Green Network, such as locations of interest or where change is occurring or expected.    View this dataset in our walking counts app.  For more information on walking counts, visit the City of Sydney website.

Kangaroo Management Zones

This polygon boundary layer contains 15 Kangaroo Management Zones relating to the commercial kangaroo harvest management program in the western part of the State. A "Non Commercial Zone" extends across the Eastern Seaboard.

The commercial harvest of kangaroos in New South Wales is restricted to distinct kangaroo management zones. Kangaroo management zones are used to allocate and issue harvesting quotas. These quotas limit the number of kangaroos of each species that may be harmed commercially in any kangaroo management zone.  Annual harvest quotas for each management zones are established using population estimates calculated from annual population monitoring and reporting.

The attribute table contains both the full area hectares and square kilometres as well as the values of those two fields with NPWS Estate subtracted ie. where there is no harvest.

NB. In 2020 the zone boundaries were modified in the southern part of the State:

•   the former single Griffith zone was divided into Griffith North and Griffith South and the southern Griffith Zone was extended east

•   the South East Tablelands zone was extended slightly east into the non commercial zone.

The 2020 version remains the current one.

Climate Vulnerability Assessment: Wine Grapes Warm Region

The <strong>Climate Vulnerability Assessment</strong> was designed to provide an overview of the impact of future climate change on all stages of production for the commodities and biosecurity risks assessed. The project used multicriteria analysis (MCA) models to produce assessments for the commodities and biosecurity risks in a consistent and comparable way, and a framework was developed to provide a rigorous, flexible and transparent process for assessing vulnerabilities and opportunities to climate change. Details of the approach and the climate data used in the assessments can be found in the <a href="https://www.dpi.nsw.gov.au/dpi/climate/climate-vulnerability-assessment/publications-and-reports">Methodology Report</a> which also details model exclusions and assumptions.

Assessments were undertaken on commodities grouped into 6 nodes: <em>Horticulture and Viticulture</em>, <em>Broadacre Cropping</em>, <em>Forestry</em>, <em>Extensive Livestock</em>, <em>Marine Fisheries</em>, as well as for a set of biosecurity risks related to these primary industry sectors. The <a href="https://www.dpi.nsw.gov.au/dpi/climate/climate-vulnerability-assessment/publications-and-reports">Summary Report</a> gives details of the chosen commodities and biosecurity risks and summarises the high-level results.

Results Reports for each commodity and biosecurity risk are being released. Visit the <a href="https://www.dpi.nsw.gov.au/dpi/climate/climate-vulnerability-assessment">project's web pages</a> to access these reports and for further information.

This dataset contains maps of modelled climate suitability for the <strong>warm-region wine grapes</strong> model in the Horticulture and Viticulture node of the DPIRD Climate Vulnerability Assessment. Maps are provided (in GeoTIFF format) for each element of the model: the overall climate suitability, climate suitability maps for each phenophase and also for each phenophase/climate variable combination in the model. Data is provided for each of the eight global climate models (GCMs) used in the project, as well as the climate suitability derived from historical observations, along with the ensemble median for each map.

Fire Extent and Severity Mapping (FESM) 2017/18

Fire severity is a metric of the loss of biomass caused by fire. In collaboration with the NSW Rural Fire Service, DPE Remote Sensing &amp; Regulatory Mapping team has developed a semi-automated approach to mapping fire extent and severity through a machine learning framework based on sentinel 2 satellite imagery. The statewide severity map has standardised classes to allow comparison of different fires across the landscape. The FESM severity classes include: unburnt, low severity (burnt understory, unburnt canopy), moderate severity (partial canopy scorch), high severity (complete canopy scorch, partial canopy consumption), extreme (full canopy consumption).

This dataset represents the 2017/18 fire year, including wildfires &gt;100ha with fire start date between July 2017 and June 2018.
