Restoration in fragmented landscapes – The importance of genetics :: Linda Broadhurst, CSIRO :: AABR Forum 2016

The million dollar question of 'provenance' is eloquently described by Linda Broadhurst within the context of habitat fragmentation and climate change impacts. The talk simply explains the role of genetics in understanding inbreeding depressions and how they can arise from small population sizes or reduced parental numbers. A must see video for anyone who collects [...]

 

Genetics and Restoration :: Linda Broadhurst and Tein McDonald :: Discussion 2016

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 [...]

 

Using the Atlas of Living Australia to assist provenance selection for restoration plantings under climate change :: Trevor Booth, CSIRO :: AABR Forum 2016

How do you work out what plants are suitable to grow in a climate changing world? Trevor Booth outlines a process using readily available web tools, the Atlas of Living Australia along side the Climate change in Australia website, which enables a variety of climate change scenarios to be considered and the location of potential [...]

 

Local provenance and more distant seed sources; fragmented landscapes and climate change :: Nola Hancock :: Seminar 2013

,

Nola Hancock’s talk on local provenance and more distant seed sources tackled the big question. Does seed from the local site perform better? Nola’s conclusion is that mixing seed sources are best. In addition the disadvantages of local provenance were that due to the fragmentation of the landscape, population sizes are smaller which increases inbreeding [...]

 

Goals and logistics of restoring grassy understoreys on mined land in the Hunter :: Tim Berryman :: Seminar 2014

, ,

Tim Berryman is at the coalface of restoration, developing strategies and processes to reinstate grassy understory local plant assemblages on mine rehabilitation sites. This presentation outines the who, what, where, when, why and how of grassy understory restoration. Tim discusses the importance of partnerships and the need to push the boundaries in order to develop [...]

 

Cumberland Plain Seed production facility, Greening Australia. Paul Gibson-Roy. Field day 2015

, ,

Greening Australia’s Cumberland Plain seed production facility is a real eye opener. You can see how they set up a low cost facility that allows for efficient harvesting and promotes genetic diversity. This protects remnants from over-exploitation and allows for much greater quantities of seed to be harvested more economically. Topic Mins: seconds Purpose [...]

 

Mount Annan Cumberland Plain seed production area, Australian Botanic Garden :: Peter Cuneo, Jordan Smith and Gavin Phillips :: Field day 2015

,

The Mt Annan seed production facility is focussed around growing native grasses for revegetation. The video covers the learning that has evolved to understand the process behind the establishment of the seed production areas. Topic Mins: seconds Purpose 00:18 – 00:47 Species, densities and area 00:47 – 2:30 and 9:17 – 9:32 Site preparation [...]

Seed and plant production areas & genetic issues

,

These resources explore the issues around species selection and provenance within the context of a fragmented landscape in a climate-changing world. The fact sheet provides a summary of Principles 1 and 3 and Appendix 3 from the National Restoration Standards. The student worksheets investigate establishing seed production facilities and provenance selection to optimise species’ resilience.
