The firebreak need be wide enough to contain the flames during the application of the back fire. When the head fire is applied, its flames are blown away from the firebreak into the areas to be burned. It is proposed that a firebreak of 4 to 8 m wide be maintain around the property boundary. The existing road infrastructure can be used as efficient firebreaks and should be sufficient in stopping a fire. No additional firebreaks are required. BURNING PROCEDURE The National Act on veld and forest fires (Act no 101 of 1998) has in mind that government bodies, property owners, institutions and association be collectively held responsible for the prevention and management of fires. It is thus, in the interest of individual property owners that they or a representative be actively involved with a local fire prevention association. It is recommended that the local fire prevention unit be informed before implementing a burn and their co-operation obtained in controlling the fire. The following rules should be kept in mind to prevent a fire from getting out of control: Make and maintain effective firebreaks on the borders of the area. Inform residents and neighbours before burning a boundary firebreak. It is preferable to plan and burn boundary firebreaks in co-operation with neighbours. The neighbours’ presence must be insisted upon when burning on the boundary. Wait for suitable weather. On a windy day fires can easily get out of control. Burn the firebreaks before the grass becomes so dry that it becomes a fire hazard. Never light a fire where it cannot be controlled. Do everything possible to prevent a fire from spreading. Never leave a fire unattended before it is fully extinguished. Any burning operation should start along a firebreak as a back burn. The back burn should be allowed to burn for a sufficient distance to ensure the safety of the area downwind of the fire. Once this have been done, a fire line is set along the upwind margin of the paddock, so that the greater proportion of the area is burned out by a head fire. A dip torch is a useful tool for setting such fire lines. Recommendations for Marloth Park A mosaic pattern of veld burning is often applied on farms to maintain a sound species and habitat diversity in the vegetation. The main reason for burning on any property is for the removal of unacceptable material. The type of fire, which is therefore required, is a low intensity fire. © Ecological Associates/ Marloth Park 107
A low intensity fire will be achieved by burning when the following environmental conditions are present in the area to burn: the air temperature should be below 20 ºC, the relative humidity above 50 percent and the soil moist. This means that burning must preferably take place during the morning before 11h00. The fuel load must also be at least 2000 kg/ha for the fire to be carried. Fuel loads for each management unit must be determined annually before implementing a burn. All plant communities, with exception of the Dichrostachys cinerea – Tragus berteronianus Low bushland has sufficient biomass to sustain a burn. However, burning in Marloth Park is not recommended due to the high risk of property damage. As fire is only recommended to reduce biomass and remove moribund plant material, it is recommended that an alternative method be applied to simulate the same action. Although the Leitner box method can be used, this method is labour intensive. The box consists of a rectangular structure that can be manually moved from section to section, after burning the vegetation inside the box. The best alternative is to slash the vegetation manually. It is recommended that herbaceous biomass production be measured annually and priority areas identified that require a slashing programme. Property owners must be convinced of the necessity of removing the excess material, not only for the health of the vegetation but to reduce the risk of natural or accidental fires that can damage or destroy their residence. As property owners generally do not have the equipment, labour or time to implement such a programme, it is recommended that an independent consultant be contracted to achieve the desired results. Although burning of Marloth Park during the 2006 season will not be required, it is recommended that a proactive system be implemented that will be able to deal with excessive biomass production. Based on the high rainfall experienced in the 2005/2006 seasons it can be expected that the effects on the vegetation will be most noticeable in the next 2 years, pending seasonal follow-up. SOIL EROSION Degraded ranch land is highly susceptible to soil erosion because of their low basal grass cover and their slow recovery rate in terms of grass cover. Especially those wildlife areas that start as a trampled livestock ranch face problems of soil erosion. Soil erosion leads to the loss of fertile soil, depositing of unproductive soil on fertile land, desiccation of soil in the vicinity of gullies due to excessive drainage and the undermining of infrastructure facilities and roads. Furthermore, erosion ditches disturb the pristine appearance of the landscape, reducing the areas tourism potential. Soil erosion is a natural process and cannot be prevented. © Ecological Associates/ Marloth Park 108
