The future for biodiversity conservation isn’t more national parks

Today we begin a series on Australia’s endangered species and how best to conserve them. The series will run each Thursday, and begins with this excerpt from Tim Flannery’s Quarterly Essay, After the Future…
Invertebrates can seem alien and “other”, but the world can’t get by without them. Thomas Shahan

Ignoring invertebrate conservation is simply spineless

Invertebrates are all around us – crawling, squirming and buzzing about their business. From forests canopies to ocean depths, they form about 80% of the known species on Earth. By virtue of their sheer…
There are sound ecological reasons for introducing grazing animals to some wild areas, but this shouldn’t act as a cover for non-scientific grazing. Richard Lehnert

Can livestock grazing benefit biodiversity?

Grazing by livestock (mainly sheep and cattle) has irreversibly degraded many natural ecosystems in Australia. Consequently, stock are usually removed from public land when new conservation reserves are…
Ants might be a pain … but they play a vital role in maintaining the variety of plant life we see around us. mraandrews

In defence of the humble ant, champion of biodiversity

You’d be hard pressed to find many people who hold ants in high regard. That might be due to their destructive behaviour towards lawns, their ability to infest your house in no time at all, or a willingness…

Competition: warming and its effect on biodiversity

In 2008, I and my colleagues published a study which appeared to confirm that current global warming could cause large losses of species and a loss of biodiversity. Four years later and a new approach…
A new CSIRO report calls for a rethink on national parks management in the face of climate change. AAP

Climate change requires national parks rethink: CSIRO

The government must consider expanding the network of protected national parks and reserves in order to address a climate change-driven loss of biodiversity, argue the authors of a new report from the…

Amidst all the heat and noise of the Rio+20 Conference on Sustainable Development, the release of WWF’s Ecological Footprint analysis for Australia in May went largely unheralded in the general media…
No simple matter: logging and conservation are not polar opposites, and controlled harvesting can fund the protection of forests. AAP/Greenpeace/Jeremy Sutton-Hibbert

Can forest conservation and logging be reconciled?

Is there a role for logging in ensuring the future of the world’s tropical forests and their rich diversity of plants and animals? For many this idea is absurd, because timber production achieving conservation…
Extinct: the Christmas Island Pipistrelle. Lindy Lumsden

Threat of extinction demands fast and decisive action

When it comes to mammal extinctions, Australia’s track record over the last 200 years has been abysmal. Since European settlement, nearly half of the world’s mammalian extinctions have occurred in Australia…

Seeing the wood for the trees: Kiwi lead in biodiversity conservation

In 1992-93, 168 countries including Australia and New Zealand signed the Convention on Biological Diversity (CBD) acknowledging an urgent need to halt ongoing decline in the planet’s biodiversity. In its…

Ecology is failing and needs to be freed from our limitations

The splendour of nature diminishes day by day despite the strenuous efforts of ecologists and all manner of scientific understandings and interventions. Biodiversity is in decline, and crucial resources…
Hard numbers: less than 1% of the world’s oceans are protected but marine scientists think 20% should be off-limits to fishing. AAP/Lloyd Jones

Marine parks: cause for optimism, but devilish details

As a marine scientist, I welcome Senator Burke’s brave decision today to roll out Australia’s marine park system. This puts us on a par with other leading nations like the US and UK who have established…
Darkness visible: we’re driving animals to extinction, burning through resources, and throwing out natural balances, yet consumption still reigns. Flickr/NASA's Marshall Space Flight Center

State of the future: challenge one; sustainable development and climate change

State of the Future 2012, a quick introduction What is the “state of the future”? How successfully are we tackling global challenges threatening our collective future? These questions are asked annually…
