Within DIDMS the term Phytophthora cinnamomi is referred to as Pc.
The data in DIDMS is suitable for general overview, general scoping, broad scale planning (>1:100,000), and educational purposes.
The data is NOT suitable for operational or environmental impact assessment purposes.
It is the responsibility of the DIDMS user to acquire permission from the custodian/owner of the data presented within DIDMS to use beyond the conditions outlined in this disclaimer.
The data within DIDMS may NOT be comprehensive, up to date, vary in scale and quality.
Phytophthora Dieback disease Information is considered current up to 12 months within its survey date capture.
If a User zooms beyond a datasets scale view setting within DIDMS it will DISAPPEAR from view to part protect the data being used beyond its accuracy of scale capture.
Areas that have not been mapped MAY still be infested, until stated otherwise by a “Registered Phytophthora Dieback Interpreters”.
The professional standard of Phytophthora Dieback disease mapping is set by Department of Parks and Wildlife’s Forests and Ecosystems Management Division and applied by “Registered Phytophthora Dieback Interpreters”.
Pc disease status data will not meet Department of Parks and Wildlife standards unless it has been collected by a registered Phytophthora Dieback Interpreter.
The ONUS of data quality is with the DIDMS User when uploading data.
It is the responsibility of the DIDMS user to acquire permission from the client and/or landholder prior to uploading Phytophthora Dieback disease data collected on their clients, or first party’s behalf.
Ownership and custodianship of uploaded DIDMS data is the responsibility of the DIDMS user to define.
“Disease Points” Data:
It is important to note that “Pc negative” sample points do not necessarily confirm the absence of Pc (Refer to Point 5a, 6 and 7).
There is a degree of uncertainty in “Pc negative” sample points which can result in a “false negative”.
“False negative” uncertainty is reduced, but not eliminated, when a registered Phytophthora Dieback Interpreter undertakes the sampling (refer to Points 6, and 7).
The chances “Pc positive” samples resulting in a “false positive” are less likely than a “Pc negative” result when appropriate sampling techniques and hygiene are applied.
“Disease Confidence Mapping Pc to June 2008” DIDMS Baselayer Data:
The Phytophthora disease boundaries and categories portrayed in this dataset are a composite of survey data collected at varying times over 30 years.
The dataset comprises various scales of survey intensity and should be used according to Points 2 and 3.
The extent of infestations are underestimated, as not all areas have been surveyed and disease boundaries are likely to extend into mapped disease free areas since surveys were conducted (Refer to Point 5a).
Disease Confidence Mapping should be viewed with the overlayed DIDMS “Pc points on Public Lands” dataset.
