What this subject covers

How forest fires start and spread, their ecological roles and impacts, and how fire is prevented, detected, suppressed and used deliberately.

In the exams: ICAR AICE-JRF 59 Unit 8 (forest fires: causes, types, impacts, control); IFoS Forestry Paper II Section B (forest protection); NWCG qualifications (USA)

What State Forest Service asks from it

State Forest Service, Range Forest Officer and Forester exams, India

Fire lines and their maintenance, controlled and early burning, fire watchers and organisation, the fire season and types of fire.

10 practice questions, worked

Choose an answer, then open the working. Each explanation says why the right answer is right and why the others are not.

1 · Fire triangle and combustion · easy

The three elements of the fire triangle are:

  1. Fuel, wind and slope
  2. Water, soil and sunlight
  3. Fuel, oxygen and heat
  4. Trees, grass and people
Answer and working

C. Fuel, oxygen and heat

Remove any one and the fire goes out. Fuel, weather and topography form the fire behaviour triangle.

2 · Fuels: types, loads and moisture · medium

Which dead fuels belong to the 1-hour timelag class?

  1. Branches about 2.5–7.6 cm in diameter
  2. Logs about 7.6–20 cm in diameter
  3. Stumps, buried roots and logs over 20 cm
  4. Grass, needles and twigs under about 0.6 cm
Answer and working

D. Grass, needles and twigs under about 0.6 cm

1-h fuels respond to humidity within hours and drive fire spread.

3 · Types of fire: ground, surface, crown · easy

The most common type of forest fire in India is the:

  1. Crown fire
  2. Ground fire
  3. Surface fire
  4. Independent crown fire
Answer and working

C. Surface fire

Most Indian forest fires burn litter, grass and undergrowth.

4 · Fire weather and fire danger rating · medium

In most of India, fire danger peaks during:

  1. The peak of the monsoon
  2. The hot, dry pre-monsoon months
  3. Mid-winter fog
  4. The retreating monsoon in October
Answer and working

B. The hot, dry pre-monsoon months

Roughly March to May, with dry litter, low humidity and strong winds.

5 · Fire weather and fire danger rating · medium

Fire danger ratings are used mainly to:

  1. Measure the timber volume burned in each compartment
  2. Classify soils after fire
  3. Set readiness, restrictions and warnings
  4. Count wildlife after fire
Answer and working

C. Set readiness, restrictions and warnings

They guide preparedness, burning bans and resource positioning.

6 · Fire prevention and fire lines · medium

Why are fire lines in India cleared and burned before the fire season?

  1. To create ash that fertilises the forest for next year
  2. So the cleared strip cannot itself carry fire
  3. To attract wildlife away from roads
  4. To mark compartment boundaries for felling
Answer and working

B. So the cleared strip cannot itself carry fire

Burning the debris removes fuel from the strip.

7 · Detection: lookouts, satellites, early warning · easy

Lookout towers locate fires by:

  1. Measuring the temperature of the smoke plume
  2. Counting burned trees
  3. Weighing ash
  4. Cross-bearings from two or more towers
Answer and working

D. Cross-bearings from two or more towers

Intersecting bearings fix the position.

8 · Suppression methods and organisation (Incident Command System) · easy

Direct attack means working:

  1. Far ahead of the fire
  2. Only from aircraft
  3. Only at night
  4. At the fire edge
Answer and working

D. At the fire edge

Suitable for low-intensity fires.

9 · Suppression methods and organisation (Incident Command System) · medium

Mop-up means:

  1. Clearing fire lines before the fire season
  2. Measuring the burned area
  3. Putting out remaining burning material
  4. Planting trees after fire
Answer and working

C. Putting out remaining burning material

It prevents re-ignition.

10 · Community-based fire management · easy

Community-based fire management mainly involves:

  1. Only aircraft and professional crews from the city
  2. Banning all people from forests
  3. Burning forests every year
  4. Local people in prevention, detection and suppression
Answer and working

D. Local people in prevention, detection and suppression

Communities are present, knowledgeable and interested in forest products.
