Change log

Updates to enable Perceptions of Practice Survey reporting of were implemented. This means projects submitted to P2R Reporting can no longer be deleted. You can create archive folders if you wish to hide old projects.
There was also a minor update to notification emails regarding projects selected for review, where Group Admins also receive a notification in addition to project owners.

The Pesticide project type replaces the pesticide questions in the Cane project type and enables consistent reporting on Pesticides for Cane, Bananas, Grains and Horticulture. This will calculate the change in aquatic risk through changing pesticide products and/or volumes of pesticides applied including different spray methods.

New program management functionality has been implemented to support the Governance and Review of Reef Programs and a new project type ‘Other’ developed as a catch-all for those activities not currently calculated within P2R Projector e.g. wetland revegetation.

The method now automatically runs the HowLeaky model for the specified project to tailor predicted water quality improvements to the parameters of the project. All existing grains/bananas projects will require migration to the new version. P2R Projector will offer you the opportunity to download existing project details before you apply the migration. For more details see here for grains and here for bananas.

P2R Projector’s use of Cross Section observations to calculate gully and streambank geometric characteristics has been upgraded to ensure that average values better represent the number of cross section entries provided. The Cross Section component of the Projector survey allows for 5 entries, existing surveys providing fewer than 5 cross section entries will need to be recalculated to make use of the upgraded interface.

The perceptions of practice surveys’ privacy/informed consent statements have been updated

A calculation error that resulted in an underestimation of estimated  sediment saving for Streambank projects that utilise the Catchment Modelled Method has been corrected.

Reef Investor

The Reef Investor is accessible by investment program owners (Qld and and Federal Government). It provides aggregated reporting on progress of investment programs.

Project Status and Costs

Project status functionality and a more detailed breakdown of costs has been added to all projects to provide a better resolution of the project pipeline and costs in the Reef Investor.

Hillslope Erosion 

The K factor layer and the S factor layers used in the Universal Soil Loss Equation (USLE) to predict fine sediment savings from grazing management projects have been replaced by new layers developed by the Qld Government. This affects all existing grazing projects, and they will need to be recalculated before any further editing can occur.

Project Linking

Gully and streambank projects can be linked to associated grazing projects prior to submitting for external review. This allows reviewers to consider a collective gully, stream and grazing activities occurring on a property.

Perception of Practice Survey 

Perception of practice survey is now restricted to in progress and completed projects. To be able to access the perception of practice survey a project must be either in progress or completed.

Gully and Stream Erosion Control Activities

Gully and stream erosion control activities update. The fencing option has been split into 2. We now have fencing new and fencing existing.

Gully and Stream Project Review Evidence

Gully and stream project review now have 2 new evidences. Concept design report and detailed design report.

The calculation of erosion rates (and therefore sediment savings) requires each gully and streambank project to have valid soil attribute values for Bulk Density and Fine Sediment Percentage. Additionally, calculation of associated particulate nutrient savings (Nitrogen and Phosphorus) require each project to have valid data values for soil nutrient concentration. To facilitate project initiation, these soil attribute are initialised using automated data retrieval from relevant data sources. Sometimes these data sources are unavailable for interrogation. When P2R Projector encounters issues with the retrieval of soil attribute values, a default value of 0 (zero) will be entered into the computation. In most cases you can manually enter a value that you are happy with to replace the zero value, thus providing reasonable erosion estimates.

The unit attributes for particulate nitrogen and particulate phosphorus reductions in Spatial Data (pn_unit, pp_unit) and Detailed Results (Particulate N Unit, Particulate P Unit) export files have been changed to ‘kg’ from ‘tonne’. The numeric value of particulate nutrient reductions has not changed, and have been calculated and displayed correctly as kilograms in the P2R Projector interface. Accordingly, column names in exported Project level summary and Block level summary files will be updated, with Total Particulate N (t) and Total Particulate P (t) replaced with Total Particulate N (kg) and Total Particulate P (kg).

Any data downloaded between the 7^th and 15^th of November 2023 for stream and gully projects will have the particulate nitrogen and particulate phosphorus values labelled as tonnes when they are actually calculated as kilograms.

Gully and Streambank project types

The functionality of the Reef Trust Gully and Streambank Toolbox has been incorporated into P2R Projector as two separate project types (Gully and Streambank). This has resulted in removing these project types from the existing Grazing project type. The Grazing project type now handles hillslope erosion from broadacre grazing only.  Details of the new methods are presented here (https://p2rprojector.net.au/how-it-works/gully-streambank-projects/)

Revision of Grazing hillslope method

The hillslope erosion method used to determine fine sediment saving from Grazing project types has been updated to better align with Paddock to Reef catchment modelling methods. The method is described here https://p2rprojector.net.au/how-it-works/grazing-projects/.

Interface functionality

The interface and workflow of the P2R Projector has been updated to allow for the incorporation of the new project types. Videos demonstrating the new interface can be found here  https://p2rprojector.net.au/support/tutorials/.

Project type – Collection mapping

Collections now only handle a single project type. That is, all Projects within a Collection must be of the same project type.

A recent update implemented autodetection of the industry type for an imported collection and the popup to to allow users to select the industry type was removed as part of that update. This created a problem for importing spatial files that were yet to have an industry associated with them. The import popup has been re-instated to confirm industry type selection. Additionally, the interpretation of attributes when importing of Grazing industry collections has been broadened.

User Management

In anticipation of upcoming functionality to allow external project review, the interface to allow user management setting and user management roles has been updated to make user role management clearer.

Detailed results download

The detailed results download has had the calculated management practice grade fields returned. These fields had been dropped from the output in a previous update. However, some users were relying on these fields and requested that they be returned.

The number of files created for detailed results download has been reduced to only produce a file for each industry/project type that exists for the collection being downloaded.

The Perceptions of Practice (AKA social survey) survey developed by the Office of Great Barrier Reef, Human Dimensions team has been implemented within P2R Projector. Perceptions of Practice surveys can be conducted from within P2R Projector at two project stages ‘Initial’ and ‘Implemented’ .

The previous release (04 November 2022), constrained the upper and lower limits of stream sediment generation, resulting in some large reductions in predicted sediment saving from riparian management. The constraints on the upper and lower limits of sediment generation have been expanded, but still exclude unrealistically high sediment generation rates.

A minor fix has also been applied where the donor inkind time field for a project was populated with the inkind cash value when a project was re-opened. The correct mapping now applies.

Sugarcane
Changes for the Sugarcane industry in this version:

• The method of predicting the nitrogen reduction has changed to a nitrogen use efficiency approach for selecting the underlying modelling simulation
• Predicted nitrogen savings are more sensitive to changes in nitrogen application rates.
• The application of mill mud no longer impacts the project scale nitrogen balance. That is, changing the mill mud application rate in the management practice survey will not result in a predicted change in project level nitrogen saving.

Grazing

• For stream bank related sediment saving predictions, we have revised down the sediment savings from large streams to be the same as for medium streams.

Grain

• The soils layer for grain has had a very minor update to add a missing soil code to a small number of soil polygons.

Other Improvements
We have implemented:

• the ‘spatial wrangler’ functionality to help handle large collections with overlapping projects and multiyear reporting.
• a ‘change layer’ functionality to help handle projects that overlap with projects from previous years.
• another export option for those with large collections to report aggregate changes in practice across catchments.
• minor changes to export field formatting to improve compatibility with related data systems.

First version of grazing industry functionality released. Including pasture management, streambank management and gully management via input of results from the gully toolbox.

Additional functionality changes included in this release that apply across all industries:

• A higher resolution zoom to allow more precise mapping.
• Labelling of submitted project collections with the group they came from.
• Better support for importing of partially completed surveys (e.g. when only the before questions have been answered)
• Explainer page for Delivery Ratios

Paddock modelling simulations for the Grain and Banana industries are not conducted for all soils and management practice combinations in all regions. In order to allow a result to be calculated, P2R Projector maps the next most similar soil type where a simulation exists. No-results cases can still occur where there is not a suitably similar soil type with a modelling simulation.

When anything changes that should require a recalculation at the industry level, then the ‘survey version’ of projects is incremented. The activities that may require a recalculation are revisions in simulations, or changes to soil or climate mapping or management practice survey or weighting changes or delivery ratio changes. When opening or importing a collection, if the ‘survey version’ of any projects in a collection do not match the current ‘survey version’, then a popup will appear, requesting a recalculation.

Grain industry

First release of the grain industry. Covers the Burdekin and Fitzory regions only. Includes fine sediment generation only.

Banana Industry V2

Banana industry version 2 release. based on revised paddock modelling simulation to reflect updated management practice adoption survey. All existing Banana industry projects will need to be migrated to the new version. This migration occurs via an automatic detection of version when a collection is selected. A popup prompts migration.

Sugarcane Schema alignment

Question 13 of the sugarcane management practice survey was inconsistent with the numbering schema used in the Collector App. Specifically, P2R Projector had no Q13.2 response.

App Version 3

P2R Projector has been completely rebuilt and released in this major version update.

Delivery to reef

All reported water quality savings are savings at end of system. This is achieved by applying a constituent specific delivery ratio for each underlying SORCE subcatchment.  The delivery to stream values can still be determined from the detailed results download which includes the constituent delivery ratio which can be used to back-calculate the delivery to stream.
