Lord Howe Island

LORD HOWE ISLAND in Australia This island paradise is like a giant garden, with more than 240 indigenous plant species living in its rainforest­s, grasslands and other ecosystems, writes LIANI SOLARI

Lord Howe Island is so extraordin­ary it is almost unbelievab­le,” wrote Sir David Attenborou­gh of his 1998 visit to the World Heritage-listed isle located 600km east of the Australian mainland. A biodiverse paradise, the ancient volcanic island was untouched by humans until its discovery in 1788 by First Fleeters, who thought they’d chanced upon “the Golden Age as described by Ovid”. It’s a comparison echoed today in references to the 15km2 island as “the last paradise on earth” and “Australia’s own Garden of Eden”.

Since the isle’s discovery, a number of indigenous species of flora and fauna have been threatened, even decimated, by human activity, weeds and exotic pests, and a giant black nocturnal stick insect has become the improbable pin-up for conservati­on efforts to protect the island paradise. Dubbed the tree lobster, the Lord Howe Island stick insect (Dryococelu­s australis) was assumed extinct for 80 years until it was rediscover­ed in 2001 on Ball’s Pyramid, a barren sea stack 23km offshore. This ‘Lazarus species’ was saved by a plant: the single tea tree (Melaleuca howeana) on which the flightless creatures were found clinging to life, the shrub itself defying death on the sheer, exposed rock face.

While the insurance population of the world’s rarest insect waits to be reintroduc­ed to its ideal forest habitat, there’s nothing stopping you from exploring the two-thirds of the island

covered in natural forest, including oceanic rainforest­s dominated by banyans (Ficus macrophyll­a subsp. columnaris), forky-trees (Pandanus forsteri) or the endemic kentia palm (Howea forsterian­a) that became all the rage as an indoor plant in Victorian Europe.

You can navigate much of the forest yourself via well-marked walking tracks graded from Class 2 (no bushwalkin­g experience required) to Class 4 (suitable for experience­d bushwalker­s). Several easy and intermedia­te walks start from the middle of the island, where the homes

and tourism businesses of the 350 residents are concentrat­ed. Other habitats to explore include maritime grasslands and white-sand beaches, swamp forests, saltmarsh, and the shrublands of coastal rock shelves and cliffs.

For very experience­d hikers, the

Class 5 rope-assisted walk to the peak of Mount Gower (875m elevation) takes 8–10 hours with a licensed guide. It’s the only way to see all four of the island’s native palm species on the one walk, as the critically endangered little mountain palm (Lepidorrha­chis mooreana) grows exclusivel­y at the summit.

When you reach the gnarled mossy cloud forest at the top of Mount Gower, take in a breath of moist, cool air, along with the remarkable fact that most of the vascular plant species at the island’s highest point occur nowhere else on earth. On a clear day you can see the entire island. But if your view is obscured by clouds, know that the moisture-dependent plants at the summit, such as the delicate epiphytic orchid Dendrobium moorei, are in their happy place.

From March to October, the upper slopes of Mount Gower (and adjacent Mount Lidgbird) are virtually the only breeding places in the world of the migratory providence petrel. Unafraid of humans, these wild seabirds will come to you when called. And you won’t miss out on seeing them if you don’t scale the mountain, as the Little Island Track is a flat walk to the base, via a light-speckled kentia grove, where you can also summon the birds. Paradise found.

NEED TO KNOW

Lord Howe Island is a two-hour QantasLink flight from Sydney or Brisbane, or an Eastern Air Services flight from Port Macquarie. There’s no mobile phone coverage, but public phones and internet are available in town. Accommodat­ion includes lodges, guesthouse­s and apartments. Most amenities are within walking distance, but there are bicycles and some rental cars for hire. Before you visit, read The Australian Geographic Book of Lord Howe Island by Ian Hutton with the foreword by Sir David Attenborou­gh (1998), and watch the 2013 animated short film Sticky (vimeo.com/76647062) about how the Lord Howe Island stick insect was saved from extinction.
