The maintenance of Tasmania's rich and unique plant biodiversity is dependant on maintaining the ecological processes that support our species, vegetation types and their distributions in Tasmania. Any significant changes to the environment, which reduces the chances of survival, can be considered a threatening process. Such threats to Tasmanian's plant biodiversity come in many varied forms - from slow acting and widespread threats such as climate change and weed invasion through to fast acting and localised threats like minor earth works or firewood cutting. Threats may also be the result of direct human intervention such as from land clearing or as a result of indirect human intervention such as the incidental spread of plant pathogens on vehicles.
The Department addresses the management of threatening processes at a number of levels. Firstly, at the
where legislation and practical controls reduce the risk of new pests, weeds and diseases being introduced to the state. Should pests, weeds or diseases succeed in establishing in the state, DPIPWE has incursion response plans and processes in place.
Secondly, legislative controls, such as the
Threatened Species Protection Act 1995
management plans and environmental impact review processes control human actions that may threaten plant species and communities.
Lastly, the Department is engaged in monitoring and research to identify and understand threatening process and provides practical management advice to land managers.
Managing Threats to Vegetation
Pest and Diseases
A range of measures is required to effectively protect vegetation including in-situ measures such as the creation of areas set aside for the protection of vegetation and ex-situ measures such as a seed bank for insurance against extinction in the wild.
On Site (In-Situ) Protection
To ensure the full range of vegetation and communities is protected requires that areas or publicly owned and privately owned land are set aside and protected and managed for conservation via a range of measures including perpetual reservation and land management agreements of various kinds.
