At present, Harbour Esplanade is only partially complete. The roadway south of Bourke Street is yet to be developed and parts of the Victoria Harbour waterfront remain at the original elevated level with the old wharf structures.  A functional review undertaken by VicUrban identified several issues that require consideration, including lack of weather protection and confusion between pedestrian, cyclist and tram routes.

VicUrban appointed a team of consultants lead by a joint venture between Black Kosloff Knott and Taylor Cullity Lethlean (BKK/TCL) to develop concept designs for Harbour Esplanade.
Tree Logic is working as a sub-consultant to BKK/TCL providing arboricultural information to the areas of tree selection, tree planting systems complimentary to Water Sensitive Urban Design (WSUD), tree stock assessment and procurement, and tree maintenance scheduling.
The project area comprises 700 metres of public space between Docklands Drive to the north and Bourke Street (adjacent to Docklands Park) to the south.

What is believed to be the world’s tallest hardwood tree has been discovered near Forestry Tasmania’s Tahune Airwalk tourism attraction 88km south of Hobart.  One of two giant Mountain Ash (Eucalyptus regnans) found growing together, the trees were detected in August using an airborne Light Detection and Ranging Laser scanning technology (LiDAR).  The trees were subsequently located and inspected from the ground where their heights were measured.  Details of the two trees are as follow:

Name: Centurion
Height: 100 –101 metres.  Because the sight to the very top of the tree was partially obscured by the tree’s healthy crown, it may be taller. According to Forestry Tasmania staff the head of Centurion had previously broken off and it was likely the tree was once higher.
Trunk Diameter: 405 cm

Name: Triarius
Height: 86.5 metres, Clear sight to the very top of the tree.
Trunk Diameter: 390 cm

Centurion becomes the tallest known tree existing in Australia, the tallest Eucalyptus tree in the world, the tallest hardwood tree in the world, and the tallest flowering plant in the world.  The previous tallest known existing hardwood tree was “Icarus Dream”, a Mountain Ash (Eucalyptus regnans), measured at 97 metres in the Styx Valley (west of New Norfolk) in 2005.

Centurion and Triarius have survived the major bushfire events of 1934 and 1966/67, which burnt to the west and immediately east of the trees respectively.  The trees are now afforded protection through Forestry Tasmania’s Giant Trees Policy.  This policy provides for the protection and management of all Giant Trees on Tasmania’s State forests. To qualify as a Giant Tree, trees must be at least 85 metres tall or 280 cubic metres in volume.

Despite the Giant Tree policy, “El Grande” a Giant Mountain Ash discovered in 2002 was killed by Forestry Tasmania during burning in 2003 that was part of a woodland clearance exercise.  El Grande - which stood at 79 metres (260 feet) - was thought to be the largest tree in Australia in terms of volume and grew in the Florentine Valley about 100km northwest of Hobart.  El Grande collapsed last year.  Lets hope Centurion fairs better than El Grande and other Giant Trees threatened by forestry activity.

FOR IMMEDIATE RELEASE

World Experts to head National Seminar on Sustainable Systems for Urban Trees

Two international experts on sustainable systems for urban landscapes will speak at a day long national seminar in April this year. Dr Jason Grabosky on his second visit to Australia from the Department of Ecology, Evolution and Natural Resources Rutgers State University of New Jersey joins Kim Sorvig Research professor, School of Architecture and Planning, University of New Mexico who is speaking in Australia for the first time, are keynote presenters at the Sustainable Systems For Urban Trees seminar to be held in Melbourne, Sydney and Brisbane.

The two speakers are guests of Tree Logic a Melbourne based firm of Arboricultural Consultants who regularly hold seminars for landscape construction trades, municipal and commercial arborists, landscape architects, town planners/ urban designers, horticulturists and civil engineers in the areas of Urban Forestry.

The topic of the April seminar is timely with professionals facing increasing environmental challenges combined with rapid development and calls for sustainability.

“The information from the seminar will help foster more informed approaches to introducing the principles of sustainability into our landscapes” said Stephen Frank, seminar organizer and Director of Tree Logic. “Now more than ever we need to address the ethical, environmental, and technical issues of creating sustainable urban landscapes” he said. “We are thrilled to have pioneers from the field like Grabosky and Sorvig to help us achieve this”.

Joining Dr Grabosky and Mr Sorvig on their only Australian speaking engagement, is Australian expert Dr Peter Breen from EDAW (Aust) who will share his extensive experience in water sensitive urban design. Other local guest speakers will share case studies on sustainable systems that have allowed trees in urban environments to flourish.

Seminar attendees will hear first hand about latest research undertaken by Dr Grabosky on root pavement conflicts and an update on the development and application of a load-bearing soil mix to use under pavements. Kim Sorvig who has recently co-authored “Sustainable Landscape Construction: A Guide to Green Building Outdoors” is presenting on permeable/porous pavements, application, types and construction methods.
