SpeciesHundreds of tree species could potentially be grown in Queensland, but a great many would not be practical in urban environments and/or are not readily available on the commercial market. The folllowing selected genera contain some of the more popular tree species for ornamental purposes in Qld. Follow the links for more information. Please note, however, that many species referred to on these pages will nevertheless be unsuitable for small gardens, so please do your research before planting. See also Shrubs (some larger shrub species can be trained as small trees).

More shade for Brisbane pathwaysBrisbane City Council has declared that its footpaths and cycleways will be cooler and greener in the future as a result of its Neighbourhood Shadeways initiative. The aim is to increase the city's street tree population by 35000 by 2026, taking shading along residential footpaths and cycle ways to 50% from a current 35%. A range of native shade tree species will be used. Council is encouraging residents to let them know where they would like more trees planted More information: Lord Mayor's growing plan to shade Brisbane streets (October 2012) New woody weed control developed in QldA new biocontrol agent developed by the University of Queensland could mean a simple and safe way to control woody weeds. Developed from fungi which already occur in the Australian environment, the treatment is delivered as a capsule inserted into the trunk of the tree. In addition to killing the inoculated tree, the fungi could persist to kill seedlings that subsequently emerge in the area, or even untreated mature trees nearby. Commercialisation of the "bioherbicide" for control of Parkinsonia is underway, but it has the potential to control many types of other woody weeds. More information at the University of Queensland website: Australia's first bioherbicide approaching release (August 2012) Toowoomba tree plan takes trophyThe Toowoomba Street Tree Master Plan has won the Sustainable Initiatives Category in the national Parks and Leisure Australia Awards of Excellence A bloomin' great effort bags national awards (September 2012) Tree replacement won't let poisoners winIt has been confirmed that a dead Casuarina glauca on the Golden Beach foreshore was poisoned. Unfortunately, it will have to be removed. Sunshine Coast Council will promptly replaced it by a new specimen of the same species, with a high level of protection and monitoring during its establishment. Anyone convicted of poisoning a tree could face very heavy fines.

There are plans to increase tree planting in London and the rest of the country, and the methodology used in the study could with help with species selection and location of planting with respect to this form of pollution and its asssociated human health effects.

A more modest design will be implemented at the small school. Source: Theebine's School Trees Saved (April 2011) Planting guide for cyclone regions Associate Professor Betsy Jackes has written a guide based on almost 40 years of observations to help residents of north Queensland and Darwin select and cultivate trees with safety in mind. No tree is totally cyclone-proof, but factors such as the leaf type, branching structure, type of root system, conditions at planting and subsequent pruning can also affect their performance in a cyclone. You can find the guide at the Jame Cook University website here: Choosing Plants for Areas Prone to Cyclones. (March 2011) High-rise nitrogen fixation A new significance for old-growth trees in some ecosystems has been discovered in North American coastal temperate rainforests. It was already known that cyanobacteria in mosses on the forest floor fixed nitrogen, but it was found that they were more abundant in mosses growing high in the canopy. As mosses take a long time to accumulate, nitrogen input into the system can be affected by the density of very old trees. (February, 2011) Laws on neighbours' trees to receive update A draft copy of new laws designed to make disputes over trees and fences easier to resolve has been released for community consultation. It's hoped that the new laws will be better suited to the 21st century, with people today living in such close proximity. The draft bill includes clarification of the responsibilitites of the tree's owner.

A National Register of Big Trees is now being established to collect such information for Australia. Members of the public will be able to nominate native or exotic trees of significance in parks and gardens as well as natural habitats.

Source: Knowledge planted at UQ (November 2009) Can trees reduce your electricity bills? A study of homes in Sacramento, California have shown that well-positioned shade trees can reduce summer electricity use by 5 percent, but unsuitable placement can actually increase it. Further studies in other cities of the world, and in wintertime, are needed to see how trees affect electricity use across geographic locality and season. However, urban trees have potential to reduce atmospheric carbon both by reducing electricity demand and incorporating of carbon in their wood as they grow.

The good news for residents and wildlife is that after cutting back of branches and poisoning (to prevent regrowth), the trunk will be retained as a nesting site. A replacement shade tree will also be planted nearby.

In spite of the unromantic common name of "Ear Tree" (due to the shape of the seedpods), the old tree was a popular site for weddings. Staff intend to plant another one soon. Meanwhile, anyone who has a booked a function at the Ear Tree should contact the Gardens.

Free shrubs and groundcovers are to be eliminated, but shade trees will continue to be offered. The planned Residential Tree Scheme and Street Tree Scheme are part of the Council's strategy to create Australia's "most attractive and shaded city". More information at the Council's website here: Free Tree Scheme to Green the City Avenues of Honour The Avenue of Honour Project 1915-2015 aims to document, preserve and restore trees planted to honour servicemen and women in the last century, in addition to planting new ones, in time for the Centenary of the Anzac in 2015. Many coummunity groups and government bodies (including Brisbane City Council - More information about their participation HERE) are collaborating with the RSL and TREENET on this project. If you have any information about memorial trees in your district, or you would just like to learn more about the project, visit the website: TREENET Avenues of Honour Project Trees increase property values Research indicates that the top five suburbs in Brisbane (rated by median house price) are all well furnished with street trees. In contrast, some of the poorest performing areas have few trees. Read the Real Estate Institute of Queensland (REIQ) media release Feature Article
Safetree: "powerline friendly approved"A collaboration betweeen ENERGEX and Greening Australia, the Safetree program aims to encourage responsible planting under and near powerlines. This includes the powerline connected to your home. To help homeowners select appropriate tree and shrub species, a list of over 100 "Safetrees" has been developed. "Safetrees" share the following characteristics:
- suitable for south east Queensland- grow less than 4 metres tall - reasonably long lifespan - low susceptibility to pests and diseases - don't tend to shed material excessively - not poisonous - readily available The list includes native and exotic species. Some are bird attracting. Others provide shade, flowers or fruit. You're sure to find something to suit your garden in the Safetree Planting Guide, which you can download from the ENERGEX site in PDF form: www.energex.com.au/pdf/network/planting_guide_LR.pdf Alternatively, look for plants with Safetree tags and signage at participating garden centres.
