About the course

This course helps you to measure the risk of fire in grasslands.

It consists of 6 short videos, with a total screen time of 33 minutes.

The course should take about an hour to complete.

There are multiple-choice quizzes embedded in the course, so you can track your progress.

This course is helpful if you want to:

  • Understand your grassland fire risk
  • Turn your knowledge into useful data for emergency services
  • Help fire agencies manage the risk of grassland fire.
Who is the target audience?
  • Farmers and graziers
  • Firefighters
  • People who live near grasslands and wish to monitor their fire risk
  • This course originates in Victoria, Australia, but we welcome participants from anywhere!

Introduction
2 Lectures 06:53

In a major incident, grassland curing data was used to:

  • Predict fire risk in the days before the outbreak.
  • Predict fire behaviour on the day.
  • Generate warnings that went out to the public.

The Chief Officer and personnel guide you through this event.

Introduction
02:55

What we do:

Measure how dry our local grass is, once a week.


When?

During the grassland curing season, each summer.

How long does it take?

Just a few minutes.

Some resources to help you
3 Lectures 00:31

There are two resources, which are mailed to grassland curing field observers:

1. The field card

2. The field guide.

Field card

The field card is robust enough to take into your grassland. To use the field card, just fill it out with the whiteboard marker (also supplied) and once you've sent in your results, simply wipe it off for next time.

A couple of features of the field card:

1. It's colour coded.

Height is always blue, and cover % is always red. This is to avoid confusion when using the fuel load table on the reverse side.

2. It's a complete report.

If you fill out the card, you will have everything you need to make a grassland curing report.

2 pages

Field guide

This is the field guide. You can read in-depth information about grassland curing, including:

  • Fire behaviour in grasses

How do fires burn in the different curing stages? Read all about the research that's been done in this area.

  • Seed head stages

Close-up images of seed heads from different species as they go through the curing cycle.

  • Larger photos

Half-page photos of crop, native and pasture grasses at all stages of curing.

The field guide is a great resource to have at home.

Measuring your grassland
3 Lectures 14:18

What we're looking for.

To measure grassland curing, we look for the dominant grass colour, and then refine the estimate based on features like seed heads, texture and landscape features.

4 questions

Fuel loads are measured by height and cover.

Height

Measure the average height of the seed heads in the field.

Cover

This is an estimate of the density of the grass.

How much of the field card can you see through the grass?

How the map is made
1 Lecture 04:56

We now combine grassland curing data from observers with satellite data.

Satellites detect grassland curing using:

The colour of the grass

The infrared signature of the grass.
