Prescribed Burn to restore C-C Grasslands

Courtesy of the BC Wildfire Management Branch:

The Ministry of Forests, Lands and Natural Resource Operations advises that an ecosystem restoration burn is planned south of Riske Creek between April 8 and May 1, 2015, weather conditions permitting.

About 120 hectares south of Riske Creek, around Bald Mountain, will be treated to help restore native grassland ecosystems. This controlled burn is managed under the Ecosystem Restoration Program within the ministry’s Range Branch. It will be conducted with the assistance of staff from the Wildfire Management Branch’s Cariboo Fire Centre.

Historically, grasslands in the Cariboo-Chilcotin were renewed through frequent, low-intensity ground fires. Such fires prevented tree encroachment, rejuvenated understory plants and helped maintained more open grasslands and forests with large trees.

The reintroduction of managed, low-intensity ground fires to these grasslands is intended to restore and maintain the traditional grassland plant communities that are native to these areas. These managed fires also reduce the amount of combustible material (fuel load), which helps decrease the risk of catastrophic wildfires.

These fires are part of an ongoing ecosystem restoration program administered by the provincial government through the Cariboo-Chilcotin Ecosystem Restoration Committee, in consultation with First Nations, local ranchers, local forest licensees, outdoor organizations, the Fraser Basin Council, the B.C. Wildlife Federation and the Cariboo-Chilcotin Conservation Society.

FACTSHEET 

Prescribed burning used as a fire management tool

• Fire is a normal, natural process in many of British Columbia’s ecosystems. Many species of plants, birds, insects and other animals depend on fire for its regenerative properties.
• Fire helps control insects and the spread of disease in forests. It also contributes to forest regeneration, as younger trees replace older trees. Having trees of various ages in a forest helps create biodiversity. 
• Prescribed burning is one of the tools used by forest professionals to achieve land management objectives. For example, fire can be used to enhance habitat and improve forage for cattle, deer, bighorn sheep and moose. A controlled burn also can reduce fuel loads (combustible material such as underbrush and dead wood) and reduce the risk of wildfire in interface areas (where urban development borders on rural areas).
• The size and intensity of prescribed burns are carefully planned and controlled to meet management objectives for fire-maintained ecosystems. Prescribed burns are only ignited when weather conditions are favourable and when the fire will not create excessive smoke. Important factors that are used to determine the date of a burn include the venting index, temperature, humidity and wind conditions.
• The venting index is a measure of how quickly smoke will disperse under specific conditions. Prescribed fires may only be ignited on days when the forecast for the venting index is “good”.
• All prescribed burns must comply with the Environmental Management Act and the open burning smoke control regulation. This helps minimize the amount of smoke generated.
• A prescribed burn is ignited and continuously monitored by trained firefighting crews to ensure that the fire does not get out of control. The fire crew supervisor (the “burn boss”) is responsible for ensuring that the initial burn conditions are favourable and that the fire is extinguished once the prescribed burn is completed.
