EXPLORE the Great Barrier Reef with this slideshow, check the location map and get all the facts and information below.

Slideshow Description:  The slideshow ‘tells the story’ of the Gondwana Rainforests of Australia with a portfolio of photos by Peter Howard from a visit to the Border Ranges and Lamington National Parks in January 2018. It starts in the Border Ranges, where a scenic drive provides unique access to the pristine interior of the rainforest, through a range of different vegetation communities featuring an abundance of palms, ferns and other relict flora.  The road reaches the spectacular Pinnacle Lookout on the edge of escarpment, overlooking the prominent volcanic mountain mass of Wollumbin/Mt Warning (considered to be the best preserved erosion caldera in the world; see also the satellite image in the Google Earth link alongside).  From the lookout the road continues a short distance to a beech glade nature trail, where ancient trees of Antarctic Beech (Nothofagus moorei) are found in the cool temperate climate of the escarpment rim.

Descending out of the hills of the border ranges, much of the landscape has been cleared of trees and converted to pasture.  Three quarters of the rainforest that existed in Australia at the time of European arrival has been cleared in this way.  In the surrounding lowlands (and the drier parts of the Gondwana Rainforests world heritage site), Eucalypt forest replaces the closed rainforest communities and these are areas where Australia’s iconic mammals – the koala and echidna (an egg-laying monotreme) – might be encountered.

The slideshow continues with a series of photos illustrating some of the key flora and fauna in Lamington National park, centred on the Green Mountains Section of the park and the facilities around O’Reilly’s Rainforest Retreat.  Here there is a superb ‘Tree Top Walk’, which enables visitors to walk through the rainforest canopy (and even climb out into the high branches of an emergent tree for far-reaching views over the wider landscape).  In this part of the park, the courtship grounds of bower birds can be found (perhaps, as in the photo here, decorated with blue bottle tops and plastic straws rather than more natural items!) and a wealth of other rainforest birds from brushturkeys to parrots are easily observed.  Trails lead through the rainforest where vaste Hoop pine (Aruacaria cunninghamii) and fig trees are encountered and scenic spots around splendid waterfalls (such as the Elabana Falls) provide opportunities to stop and observe life in the rainforest.

Conservation Status and Prospects.  According to IUCN’s Conservation Outlook Assessment (2017) the conservation status of the Gondwana Rainforests of Australia is ‘good with some concerns’. The IUCN report notes that ‘The Gondwana Rainforests is a serial property composed of 41 component parts, ranging in size from 36 hectares to 39,120 hectares. Each of the component parts conserve different values and are faced with different threats and management responses. In general, the values for which the site was inscribed on the World Heritage List in 1986, with a large extension in 1994, have been mostly maintained apart from a decline in some significant species. While management has so far been effective in addressing some challenges, further management responses will be required to address some increasing threats, particularly those posed by invasive species and pathogens and climate change.’

Location and Values: Australia’s Great Barrier Reef is located off the country’s north-east coast and is the world’s most extensive coral reef system.  Most of the reef lies within the world heritage area, making it by far the largest world heritage site globally – significantly larger than the whole of Italy (which, incidentally, had 54 world heritage sites within its 301,000 km2 area by 2018!).  The Great Barrier Reef stretches for more than 2,000 km along the Queensland coast (corresponding with 14o of latitude), and includes some 2,500 individual reefs up to 250 km offshore.   Biologically, the area is one of the richest and most complex ecosystems on earth, with a vast mosaic of reefs, islands and coral cays that have evolved over the millennia through four glacial-interglacial cycles.  The structure and biological wealth of the present-day reef is the result of sea level changes that have periodically exposed, flooded and shaped the underwater world, which now supports an exceptionally rich marine fauna including a large number of endemic species.  This is a place where exceptional natural phenomena occur, including the annual mass spawning of corals, migration of whales, communal nesting of turtles and seabirds, as well as spectacular aggregations of spawning fish.
