NAFI Guide Booklet available
There is now a how-to guide for the NAFI website. The booklet explains how the site works beyond just viewing maps of fire information, and describes how best to use the data for fire management. It's a useful guide to the information behind the website and how to use the site through the course of the fire season. You can get a downloadable PDF copy using the link below:
Landsat Mapping Subscription Service
The NAFI team is developing a service designed to increase the effectiveness of mitigation burns by providing high resolution burnt area images to subscribers. At the landscape management scale, many smaller but operationally important early dry season burns are not effectively captured by the 250m scale mapping that NAFI provides. Landsat imagery is less frequently available but, at almost ten times the resolution is more appropriate for assessing mitigation activities.
In the example below, the image on the left shows an incendiary line appearing clearly in red on a 30 m Landsat image. Importantly, what is also clear is where there are breaks in the burn line that wildfires could move through. None of this is clear on the 250 m resolution MODIS imagery used by the NAFI maps (right), and therefore does not provide the required information for management.
The service would provide subscribers with Landsat image maps optimised for burnt area visualisation.

Methodologies and SavBAT Updates
The Darwin Centre for Bushfire Research (DCBR) has recently returned from a field trip in the western Kimberley region studying the ‘Pindan’ vegetation and its response to fire. This region forms a transition between the more monsoonal forests to the north and the semi-arid desert to the south, and consists largely of low open woodland and Acacia shrublands. The Pindan vegetation type has been ineligible as a fuel type under the Savanna Burning methodologies; the trip was undertaken to fill gaps in the knowledge of the vegetation and its fuel components.
Results of the analysis of the Pindan vegetation fuel types data need to be published internationally and peer-reviewed before assessment to enable modification of the methodology of the Savanna Burning Determination. Once this has taken place, areas of Pindan vegetation will be eligible under the Savanna Burning methodologies of the Carbon Farming Initiative.

Check out this great resource from the Central Land Council
Fire Management in Central Australia: a learning resource for Aboriginal community rangers
This pdf explains why people burn country, how fire behaves, how it is affected by the weather and how the different landscapes, plants and animals of Central Australia are affected by fire - and what has changed, It also covers how to plan and implement burning operations - who to talk to and what tools you can use, safety advice and burning techniques. There's even a guide to useful online resources and books. Everything you can poke a stick at when it comes to managing fire in the arid country of the Centre.
There's also this video from the Northern Land Council
Using the Garmin VIRB GPS Camera
This is one of a set of videos on how to use practical tools for on ground fire management that also includes the Garmin Rino 650 hand held GPS unit, and basic computer software. The videos were put together by Xavier Espiau of the Northern Land Council for their Land Air Sea Toolbox. The videos can be viewed directly here:
Or to see all the videos you can go to the Northern Fire Manager website www.firemanager.org.au and search for “toolbox”.
And this this website
Earth :: website for viewing wind conditions
The Earth :: website displays a global map that displays near-real-time wind flows, ocean current flows etc. as swirling, animated streaks. It can be useful for visualising wind strength and direction at a broad, landscape scale.
