Australian trees: exotic and native in the National Arboretum



Canberra, the capital of Australia, has marine west oceanic climate with four distinct seasons (summer, autumn, winter, and spring). Amid this climate, Canberra is well-known for its trees.

The National Arboretum Canberra, previously called the Canberra International Arboretum and Gardens, is located six kilometres from the city centre on a 250-hectare site in the Greenhills Forest, west of the Tuggeranong Parkway and Lake Burley Griffin, near the National Zoo and Aquarium. On site, trees, shrubs, and herbaceous plants are cultivated for conservation, scientific and educational study, display, and preservation. It displays trees from around the world, in addition to native trees of Australia.

The Arboretum’s forest plantings of endangered native and exotic species is a key component of the local government’s commitment to the One Million Trees initiative and is a contribution to the government’s Climate Change Strategy 2007-25: Weathering the Change. Plantings of exotic trees include: Californian Fan Plant, Chinese Tulip Tree, Persian Ironwood, Giant Sequoia, Judas Tree, Moroccan and Saharan Cypress, Norway Spruce, Taiwan Trident Maple, Canary Island Madrona, Pecan, Turkish Pine, Japanese Pagoda tree, Lebanese Cedar, and Chilean Myrtle. The Australian plantings include a variety of ironbark, gum trees, birches, and wattles.

Two of the Arboretum’s most spectacular displays are the 5,000 Himalayan Cedars and the 80-year-old Cork Oak plantation.

5000 Himalayan Cedar Plantings

Few of the thousands of cedars planted in Canberra did not survive the 2003 bush fires. The Arboretum’s planting is a living legacy to the Himalayan Cedar (deodar in Urdu – said to be a derivative of “goddess wood”). Unlike the Atlas Cedar which comes from North Africa with branches that turn upwards, or the Cedar of Lebanon with horizontal branches, the Himalayan Cedar (Cedrus deodara) has drooping branches. Indigenous to Pakistan, Afghanistan, Kashmir, and Nepal, the Himalayan Cedars have a fragrant wood with strong, straight grain. The fragrant wood is like a moth repellent, which is why it was used to construct storage chests and to make incense sticks. Unlike elongated, light pine cones, the ripe cones of the cedar are hard and shaped like barrels (7-11cm in length). The cones shed winged seeds, but the cockatoos in Canberra love to eat them – therefore there are very few self-sown seedlings. They have the ability to withstand periodic droughts in their monsoonal homelands.

80-Year-Old Cork Oak Plantation

The historic Cork Oaks (Quercus suber) are fire tolerant, hardly producing any litter. The bark provides heat protection to the trunk and the foliage does not burn easily, so they are well suited to Canberra’s climate – with the existing trees surviving the 2003 bush fire. There are two plantations of cork oak in the city and may have been planted in 1955, sourced possibly from a tree planted in 1861 near Duntroon in Canberra. The plantations have dark brown acorns set in beige cups with scales that are fringed at the rim. The leaves are glossy dark green above, and paler grey-green and hairy below, and bear five small teeth on each side.

The Arboretum continues its construction, since its establishment in 2004, and therefore there is no access on Monday to Saturday. In the future, it proposes to accommodate a bonsai pavilion, artworks, a café/restaurant, and a reflective pavilion. It is open to the public on the second Sunday of each month. However, every Sunday during the Floriade flower festival (25 September to 14 October), there are additional bus tours to the Arboretum.


Bookings are required. Please see Friends of the Arboretum website for details: www.arboretumcanberra.org.au

2016 update on Rike Park, Tbilisi: from construction to busy park

From a flat patch of uninteresting dirt, Rike Park in Tbilisi, Georgia, has transformed in four years (from 2014-2016) into a busy park full of trees, flower beds, sculptures, fountains, and events. Rike (Rikhe) Park is on the left bank of the Mt’k’vari River (the Kura River) near the Old City of Tbilisi. The Peace Bridge links the right bank to Rike Park. Rike Park is below the hillside Presidential Palace and, via cable car, it is the starting point for the ride to Sololaki Ridge (with the Narikala Fortress and the Mother of Georgia statue). The glass box-shaped cable car terminus was opened on 23 June 2012, and since then the park has continually developed into a ‘people’s park’ where people can walk around, eat at the nearby restaurants, sit next to the statue of American president Ronald Reagan, climb the steps to Avlabari district, and access the sights of Meidan Square, the Peace Bridge, the Metekhi Church, the Old City, the waterfall, the sulphur baths, and t...

The acacia thorn trees of Kenya

There are nearly 800 species of acacia trees in the world, and most don’t have thorns. The famous "whistling thorn tree" and the Umbrella Thorn tree of Kenya are species of acacia that do have thorns, or spines. Giraffes and other herbivores normally eat thorny acacia foliage, but leave the whistling thorn alone. Usually spines are no deterrent to giraffes. Their long tongues are adapted to strip the leaves from the branches despite the thorns. The thorny acacia like dry and hot conditions. The thorns typically occur in pairs and are 5-8 centimetres (2-3 inches) long. Spines can be straight or curved depending on the species.
