Natural disturbance

Federal, State and Regional agencies along with community groups and private landholders have all been striving to address the consequences of the bushfires of 2019-20. This Zoom webinar highlighted the insights, actions and opportunities that are occurring as the ecosystems transition with various levels of support.

Many plants have evolved with disturbances such as fire –It’s what triggers the resilience response within fire-adapted ecosystems, what prompts the plants to resprout and germinate. But immediately after a large disturbance like fire, the ecosystem is vulnerable, and further disturbance can easily destroy regenerating plants. Read More - Links First Aid for [...]

Weed affected bushland will need help to recover after fire, but resources are usually limited, and it's difficult to predict exactly what will happen over time. How can you make the most of your time and effort? This is an overview of post-fire site assessment. It’s a complex topic, particularly considering the extreme drought [...]

How can we help the bush to recover after fire? The native plants usually have the capacity to regenerate (unless the damage is particularly severe), but where weeds are involved, they probably need assistance. With the right approach, we can make a big difference. Here is an intro to post fire weed control, with [...]

How do you ensure your restoration project will be resilient in times of changing climate and increased fragmentation across the landscape? Tein McDonald discusses with Linda Broadhurst the implications of population size, the parental gene pool and the significance of pollinators in ensuring genetic diversity and countering inbreeding depression. In this expanding field, the importance [...]

Peggy Svoboda has been helping Saltmarsh to recover on the Hunter River Estuary near Newcastle in NSW. This video outlines the significant benefits of the restoration project as a Ramsar site of significance for migratory shorebirds and the process of constructing saltmarsh communities. Contouring of the landscape, Juncus acutus removal and riparian restoration in the [...]
