Media Release - International Day of Forests
In 2012, the United Nations General Assembly proclaimed the 21st of March every year as the International Day of Forests. The Day celebrates and raises awareness of the importance of all types of forests. The UN chooses a theme for each International Day of Forests and the theme for 2017 is Forests and Energy.
Bob Gordon, CEO of the Institute of Foresters said, ‘While the international theme is, ’ Forests and Energy, we have so much more to celebrate. IFA members have a proud history starting out as the ‘custodians’ of Australia’s forests but now work with the original custodians to ensure our children and children’s children can enjoy the beauty and bounty of our forests.
Australian and New Zealand forest researchers collaborate to extract information from LiDAR dense point clouds
Dr Christine Stone – Leader NSW Forest Science (Dept of Industry –Lands) and Dr Michael Watt – Research Leader Geometrics (SCION)
Scientists from several Australian research agencies and NZ’s SCION (formerly Forest Research Institute) are collaborating in a multidisciplinary FWPA project titled “Optimizing remotely acquired, dense point cloud data for plantation inventory”.
This collaborative Australian/New Zealand project brings together experts across a range of disciplines that do not reside collectively in any one institution. The project team has internationally recognised expertise in LiDAR & UAV technologies, software engineering and sophisticated modelling approaches. Participating research groups include the Forest Informatics team at SCION, the Terra Luma and photogrammetry research groups at the University of Tasmania, the Australian Centre forField Robotics at the University of Sydney and the NSW Lands Forest Science team, as well as two high profile forest service providers, Interpine and Indufor Asia Pacific.
This collaborative Australian/New Zealand project brings together experts across a range of disciplines that do not reside collectively in any one institution.
Significant progress has been made in the operational adoption of remotely acquired data, in particular LiDAR data, by plantation growers both in Australia and in New Zealand for the assessment of plantations. Two previouslyfunded FWPA projects have helped drive this paradigm shift in company awareness and their decision to integrate this new technology into their planning management systems. The modelling and data workflow processes developed in these projects utilise data acquired by established, commercial LiDAR sensors. The rapid advances in this technology present numerous, potential applications for improved cost efficiencies and assessment precision for timber plantation growers. New sensors can now generate 3D datasets with densities greater than 100 points/m2 including the Riegl VUX-1 LiDAR scanner (with 10mm survey-grade accuracy) and the Velodyne Lidar for UAV platforms (Figures 1a and b, 2 and 3). Datasets acquired by both these new sensors have been acquired for the project and future UAS acquisition campaigns are scheduled for both Tasmanian and NZ study sites.
The overall aim of this project is to develop and evaluate robust, optimal workflow solutions for the processing and analysis of dense point cloud datasets acquired from both LiDAR airborne and multi-rotor UAV systems flown over Pinus radiata plantations. An important component of this process is evaluation of the geometric precision of these dense point cloud datasets in order to determine if the point location accuracies are comparable with estimates derived from the manually measured trees.
The researchers will compare a suite of 3D visualisation software packages for their potential for on-screen individual tree assessment. As part of this process, collaboration with the University of Tasmania’s virtual reality laboratory is being considered. Another objective is to develop reconstructed 3D models of individual trees to estimate log product outturn. Programming techniques developed within the robotics sector will be explored as part of this objective. Finally by December 2017 the project intends to deliver recommendations to the plantation sector that will identify cost-effective options for the practical utilisation of this technology.
‘Why be a Forester’ Video Competition
Are you a keen and enthusiastic forester who wants to show the world what a great career you have? Do you want to provide inspiration to the next generation of foresters? Foresters are involved in a broad range of forest management activities relating to production, conservation, fire, water, carbon and policy. Help us educate people about the broad range of roles undertaken by foresters by creating a short 30-45 second video about how you make a difference in forest management and you can be in the running for some great prizes. First prize is a ticket to the Institute of Foresters Australia Conference 2017
held in the beautiful city of Cairns in Far North Queensland, and also includes a $500 travel/accommodation voucher from Flight Centre. Click here for all the details and even a video about how to make your video!
IFA VIC Division - Letter in response to GILLESPIE ET AL (2016) (The Victorian Naturalist Vol 133:128-138).
The IFA VIC Division recently sent a letter to The Editor of The Victorian Naturalist in relation to GILLESPIE ET AL (2016) “THE BIOLOGY AND STATUS OF THE LARGE BROWN TREE FROG (Litoria littlejohni
) IN VICTORIA” (The Victorian Naturalist Vol 133:128-138). Scientists within the Institute of Foresters examined the above paper and found several parts that are believed to show a lack of objective scientific rigour and fairness, or are incorrect. In view of this, the scientific merit in the paper has been compromised. The entire letter may be found by clicking the link: Letter to The Editor The Victorian Naturalist
Draft ERF Plantation Forestry Method
Recently, Dr Hilary Smith and the IFA Carbon Committee submitted an Emissions Reduction Fund draft determination: Draft Carbon Credits (Carbon Farrming Initiatve - Plantation Forestry) Methodology Determination 2016. The IFA has a keen interest in seeing new forestry plantations established in Australia to meet the country's growing demand for wood fibre and to contribute meaningfully to its carbon emission reduction targets through low cost abatement.
