Supplemental Information

Relationship to other Datasets: This layer reflects planning decisions which are based on a number of other layers, primarily PLM25, base topographic layers, and a large number of more specific layers covering flora and fauna, landscape, historic sites, etc. Spatial and data content errors in these layers may affect the accuracy of FMZ100. Historic Areas and Regional parks woth Limited timber harvesting is based on a draft layer called DRAFT.FMZ_PL_HARVEST. This layer provides the correct FMZ categories and boundary. Current Design Issues: The principle reason for creation of this layer is to facilitate forest management planning. In this context, the layer must be able to support both analysis and map production. Layer design must be able to support the requirements of forest conservation planning, RFA reviews, timber release plan checking, allocation order development, and forest management decision making in general. The layer supports analysis and is used for the creation of area statements. Minimum polygon size is set at 1000 m2. From this layer, a generalised layer can be derived which is used soley for map production. The generalised map product has small SPZ and SMZ areas (< 10-20ha) not shown. . Future Design Issues: To be replaced by a FMZ100 layer with boundaries adjusted where possible to 25,000 scale land tenure boundaries. Related Documents: None Current layer design is not adequate to support planning and systematic maintenance. A major review of the layer is being undertaken, with several FMAs undergoing an updated zoning process. The FMZ attribute fields describes the use in relation to timber harvesting. GMZ - General Management zones are areas where timber harvesting is permitted SPZ - special Protection Zones are areas where excluded from timber harvesting SMZ - Sepcial Management Zones

Conceptual Consistency

FMZ are the classisfication of land use into general categories for forest management. FMZ contains the forest management zone category used for conducting analysis. It includes small SPZ areas and Code of Forest Practice (CFP) exclusions. These small areas and CFP exclusions are filtered out for map production. This generalisation is reflected in FMZ_MAP. FMZ_NO identifies each SPZ and SMZ with a unique identifier that is list in the zoning scheme register of each of the Forest Management Plans. MAP_NO is the number identifying SPZ and SMZ zones that are listed in the zoning scheme register and are used in map production only. A zoning scheme register was not established for the West RFA. SPZ and SMZ numbering was identified for the draft zoning scheme published in the West RFA Consultation Paper (Jan 2000). Where polygons in the West RFA are the same as those in the West RFA Consultation Paper, the West RFA Consultation Paper numbering system has been adopted for reference to that report. Additional area of SPZ and SMZ appearing in the West RFA (but not in the West RFA Consultation Paper) may have a number assigned (identified with an asterix) but there is no published document that outlines the values protected within those zones. "Forest Management Zoning in the East Gippsland FMA does not indicate Code of Forest Practice exclusion areas. These are currently considered a wholly independent operational harvesting dataset which is no longer modelled or maintained by DSE. Since 2011 Forest Management Zone numbering in East Gippsland follows this syntax: Zone - Forest Management Block (which contains the polygons geometric centroid) - polygon number (starting at 01 for each zone / block combination). For example P-811-03 would be the third separate polygon of SPZ with its centroid in block 811. The FMZ_EG_DETAIL dataset, including all its fields has been merged into FMZ100. The idea is to maintain only one dataset for the forest management zoning. This appendix is now reflected in two items of the fmz100 layer called DESC1 and DESC2. These items contain the explaination of why the particular SPZ or SMZ area has been reserved. 

Missing Data

Once a Plan is completed, zoning will be reviewed on a yearly basis with updates being made if necessary. Changes to the layer may occur more frequently if required to facilitate forest planning. Forest management zones currently exist in a SDE layer. Forest management zones have been identified for areas where an RFA and FMP has been completed. Areas for which an RFA or FMP have not been completed, has not had forest management zones identified. A simplified map product also exists for the same area. For the Mildura FMP zoning was not completed for the whole FMA, but for a defined floodplain area, the remained of the FMA has been zoned GMZ. AREA DIFFERENCES BETWEEN FMZ100 AND THE PUBLISHED FOREST MANAGEMENT PLANS. CENTRAL HIGHLANDS - Code exclusions were not included in the area summary in the published plan. Slope exclusions were part of GMZ (GMZO: 16,000ha) and stream buffer exclusions were part of SPZ (SPC: 29,000ha). These become the 45,000 ha of Code in FMZ100. The categories OPR and OPL in the plan correspond to the categories OPR, OPL, OPT and PLT in FMZ100. A 700 ha discrepancy between the total area is due to edge match differences with the Dandenong FMA. EAST GIPPSLAND - Area statements in 1995/99 East Gippsland Forest Management Plan are now completely out of date and should not be used. GIPPSLAND - OPL category in the Plan includes the historic reserves (HRB,HRM,HRO & HRT) which are treated separately in FMZ100. All other differences (total area, waterbodies, parks and private land) are explained by the inclusion of offshore islands and large inlets in the Plan but not in FMZ100. 

Attribute Quality

Data accuracy is estimated to be GT 95%. Polygon attributes are checked several times both visually and via data values before committing to the library . Output is checked by planners and field staff during the layer definition stage. 

Positional Accuracy

Precision: 10m to 100m Determination: Based on accuracy of input covers, primarily base topographic layers. 

Lineage

Statement

Dataset Source: Majority of datasets used in the compilation would be current corporate or other library data, or would be collected during the planning process. The majority of data would be from within DSE. Source layers that led to the creation of Forest Management Zones will be entered in the Forests Zonal library at a later stage. Public Land boundaries were tied up to the new PLM25 dataset in 2012. FMZ classification of public land (PRK, PPK, OPL, etc.) were still used and PLM categories were dissolved to FMZ categories. Overlays such as remote natural areas, natural catchment areas, wilderness zones & reference area boundaries have also been updated and classified as Conservation Parks and Reserves in FMZ100 if it falls within state forests. Dataset Originality: Primary & Derived
