ENVS605 Australian Futures Environmental Essay

Question:

Which vegetation communities have been mapped as having an adverse fire regime?

What fire management strategies and activities could you put in place to achieve an optimum fire regime?

Answer:

Introduction

The Lane Cove Bational Park is beautiful pocket that has a pocket of bushland and it is located on either side of the Lane Cove River. The national is locatd not far from the Sydney’s city centre and is a perfect spot for school excursion and family day out. Due to the combination of vegetataion, topography and climate the Sydney is a bushfire prone area (nationalparks.nsw.gov.au 2018).

The vegetation communities that are mapped as having the adverse fire regime are the freshwater wetlands (Rushland), Grasslands (no particular community is represented in the reserves), heathlands (shrubland/ closed shrubland), Shrubby dry sclerophyll forests (Malllee open woodland/Open woodland/ Sydney Peppermint Woodland, Red Bloodwood, E. paniculata, E.piperita, E. haemastoma, Turpentine forest or Blackbutt, E. globoideam, A. costata), grassy dry sclerophyll forests, Sclerophyll grassy woodlands, semi-mesic grassy forests, wet sclerophyll forests (Blue Gum high forest- weed growth & dense mesic fern), saline wetlands (Mangrove), Saline wetlands (Grey mangrove low closed forest), rainforest communities (Coachwood simple rainforest) (environment.nsw.gov.au 2018).

The first and important step prior to suggesting any strategy regarding the fire management for the vegetation communities is to designate the fire interval status of the vegetation. The various levels that can be formed are: over 50 percent of the community is burned (if over 50 percent of the vegetation community is over burnt), over burnt (if the community is burnt less than the minimum levels of threshold of two or more times in succession), vulnerable (if a particular vegetation community has experienced a one interval less), recently burnt (vegetation community that has recently experienced fire), within threshold (if fire occurs this vegetation will get burnt instantly), long un-burnt (the vegetation communities have not burnt for several years) (environment.nsw.gov.au 2018).

It is important to note that the bushfires are bound to occur due to the unplanned human ignitions, fires start accidentally from the machinery, power lines, and abandoned campfires. Thus, it is always the best option to manage fires in a multi-pronged way.


Bushfire prevention strategies- the fire investigators can work along with the NSW FB, RFS and the local police to effectively investigate all the suspicious activities that are occurring within the reserves; in order to stop fire from spreading within the reserves, the best option is to close part of the reserves or parts of the reserved can be banned to prevent damage occurring from the extended fire; Al the major public entrances must have the fire danger signage in order to promote public awareness during the days of extreme fire danger; patrolling the reserve area to search the perimeter of ant wildfires during the onset of the extreme seasons; fire trails gates can be installed and the wherever necessary and the key registers can be maintained in order to control access of the organizations and agencies into the reserve premises (Bond and Mercer 2014).

Bushfire suppression strategies- annual RIPs can be prepared to maintain a contact of the NPWS staff database along with the other fire support agencies and the organizations involved with the management of the bushfires; emergency management plans can be prepared for the visitors to the reserves and clear direction can be marked for speedy evacuation, the plan will also include the provision to locate the visitors in the remote places of the reserve; demo drill can be conducted with the multiagency management team that will review the strategies with respect scenarios involving high risks (Lord et al., 2012).

Bushfire response strategies- the most important part is to take into account the fire suppression activities in the reserves. It must be ensured that the whole process is carried out with respect to the standard operating procedures; develop the public relations and the media relation strategies that will take into account the role of local community supporting the bushfire management; bushfires must be controlled according to the incident control systems that ensure the safety of the firefighters as well as the community; aircrafts can be used to access the inaccessible fires where the vital assets are at risk; remote firefighting teams can be formed that are identified through the aerial reconnaissance to minimize the fires and protect the assets; the bushfire information management system can be used to report about the fire suppression activities, the NPWS geographic information system can also be used for recording fire activities; the work programs can be modified depending on the levels of fire danger and also reduce the response time from ignition (Salmon et al., 2014).

Bushfire recovery strategies- after the operation winds down, the rehabilitation work can proceed after the suppression activities; wherever necessary, rehabilitation plans can be made in order to promote the recovery options arising from the fire operations that have significant impacts; also it is important to include the pest management controls so that the invasive pests can be controlled from spreading (Walters and Mair 2012).
