PRESCRIBED BURNING
By K. Sookee, forestry-mauritius
I
was delegated by the Forestry Service, Ministry of Agro Industry & Food
Security to follow a five-day intensive course on prescribed burning at
NELSPRUT, SOUTH AFRICA from 17th to 23rd July 2017. The course was sponsored by the SADC in
collaboration with the KISHUGU Academy and JICA, in SOUTH AFRICA.
I
wish to share the experience I gained from the workshop with my colleagues of the
Forestry Service. The lecture sessions were conducted at the KISHUGU academy
whereas the practical and the post monitoring were held in the BREAKTHROUGH
Academy.

First
of all, I would like to define the term prescribed burning. It is
a desired fire ignited by persons intentionally burning specific fuels
according to approved plans for a specific area to achieve resource management
objectives. It is a crucially important tool currently in use both
internationally and throughout Africa in plantations, grasslands and fynbos.
Prescribed
fires differ from wild fires. Prescribed fire is any non-structural fire
deliberately ignited in vegetation or natural fuels. In contrast a wild fire is an unwanted
fire. Prescribed fire in South Africa
may provide multiple benefits. It can reduce fire hazards by reducing fuels,
improving habitats for diverse wild life species, reducing competition. The
advantages of prescribed burning are that it improves wild life habitat,
manages competitive vegetation, control insects and diseases, improves forages
for grazing, enhances appearance and access to Ecotourism. It also contributes to pasture managements
through removing moribund grasses, recycle nutrients, reduces the level of
mechanical or herbicide treatment needed.
However, it has also some disadvantages on human health and welfare. The
smoke may have some negative effects on health of inhabitants and may also have
impacts on the survival of wild life.
The
lectures were conducted by experienced tutors. During the workshop a prescribed burning plan
was implemented under favourable weather conditions on a farmer’s land at NELSPRUT.
An authority was sought from the fire protection association for the
clearance of setting the fire with consideration given to the fire danger index
as set in the table below:-
The speed of the
wind, temperature, relative humidity and the wind direction were considered for
a good fire behavior. A training was given for the use of fire equipments such
as fire bats, knap sacks, drip torches, etc.
Use of Fire Bats and Protective Equipments |
After all the conditions were met, the
fire was set on the farmer’s land. Before doing so, fire-breaks were opened all
across the farmer’s land in order to avoid any escape fire. A drone was used to scrutinize the area to
see all the hazards that may be encountered such as slopes, moribund grasses,
serpents, wild life, and sensitive areas.
Use of Drone to survey the Area |
Strip burning techniques were adopted to burn
the farmer’s land. A fire team was established by the fire expert tutor
comprising of a unit leader for execution of the burning plan. The
area, some ten hectares of grass, was burnt in blocks. Drip torches were used
by a competent Officer for ignition and all equipment properly established on
site to mitigate any mishaps or any recurrence of fire. After the operation
done a post monitoring was carried out by the tutor to see if there had been any
shortcomings or discrepancies and if so, what are the future measures to
improve. The prescribed burning plan was a success.

These steps include the preliminary precautions and techniques used to ensure the success of a prescribed burning operation.
