Australia’s new marine parks plan is a case of the Emperor's new clothes

The Conversation - Mon, 2017-07-24 15:40

The federal government’s new draft marine park plans are based on an unsubstantiated premise: that protection of Australia’s ocean wildlife is consistent with activities such as fishing and oil and gas exploration.

Under the proposed plans, there would be no change to the boundaries of existing marine parks, which cover 36% of Commonwealth waters, or almost 2.4 million square kilometres. But many areas inside these boundaries will be rezoned to allow for a range of activities besides conservation.

The plans propose dividing marine parks into three types of zones:

  • Green: “National Park Zones” with full conservation protection
  • Yellow: “Habitat Protection Zones” where fishing is allowed as long as the seafloor is not harmed
  • Blue: “Special Purpose Zones” that allow for specific commercial activities.

Crucially, under the new draft plans, the amount of green zones will be almost halved, from 36% to 20% of the marine park network, whereas yellow zones will almost double from 24% to 43%, compared with when the marine parks were established in 2012.

The government has said that this approach will “allow sustainable activities like commercial fishing while protecting key conservation features”.

But like the courtiers told to admire the Emperor’s non-existent new clothes, we’re being asked to believe something to be true despite strong evidence to the contrary.

The Emperor’s unrobing

The new plans follow on from last year’s release of an independent review, commissioned by the Abbott government after suspending the previous network of marine reserves implemented under Julia Gillard in 2012.

Yet the latest draft plans, which propose to gut the network of green zones, ignore many of the recommendations made in the review, which was itself an erosion of the suspended 2012 plans.

The extent of green zones is crucial, because the science says they are the engine room of conservation. Fully protected marine national parks – with no fishing, no mining, and no oil and gas drilling – deliver far more benefits to biodiversity than other zone types.

The best estimates suggest that 30-40% of the seascape should ideally be fully protected, rather than the 20% proposed under the new plans.

Partially protected areas, such as the yellow zones that allow fishing while protecting the seabed, do not generate conservation benefits equivalent to those of full protection.

While some studies suggest that partial protection is better than nothing, others suggest that these zones offer little to no improvement relative to areas fully open to exploitation.

Frydenberg has pointed out that, under the new plans, the total area zoned as either green or yellow will rise from 60% to 63% compared with the 2012 network. But yellow is not the new green. What’s more, yellow zones have similar management costs to green zones, which means that the government is proposing to spend the same amount of money for far inferior protection. And as any decent sex-ed teacher will tell you, partial protection is a risky business.

What do the draft plans mean?

Let’s take a couple of examples, starting with the Coral Sea Marine Park. This is perhaps the most disappointing rollback in the new draft plan. The green zone, which would have been one of the largest fully protected areas on the planet, has been reduced by half to allow for fishing activity in a significantly expanded yellow zone.

Coral Sea Marine Park zoning, as recommended by Independent Review (left) and in the new draft plan (right), showing the proposed expansion of partial protection (yellow) vs full protection (green). From http://www.environment.gov.au/marinereservesreview/reports and https://parksaustralia.gov.au/marine/management/draft-plans/

This yellow zone would allow the use of pelagic longlines to fish for tuna. This is despite government statistics showing that around 30% of the catch in the Eastern Tuna and Billfish fishery consists of species that are either overexploited or uncertain in their sustainability, and the government’s own risk assessment that found these types of fishing lines are incompatible with conservation.

What this means, in effect, is that the plans to establish a world-class marine park in the Coral Sea will be significantly undermined for the sake of saving commercial tuna fishers A$4.1 million per year, or 0.3% of the total revenue from Australia’s wild-catch fisheries.

Contrast this with the A$6.4 billion generated by the Great Barrier Reef Marine Park in 2015-16, the majority of which comes from non-extractive industries.

This same erosion of protection is also proposed in Western Australia, where the government’s draft plan would reduce green zones by 43% across the largest marine parks in the region.

Zoning for the Gascoyne Marine Park as recommended by the Independent Review (left) and the new draft plan (right). http://www.environment.gov.au/marinereservesreview/reports and https://parksaustralia.gov.au/marine/management/draft-plans/

Again, this is despite clear evidence that the fishing activities occurring in these areas are not compatible with conservation. Such proposals also ignore future pressures such as deep-sea mining.

The overall effect is summarised neatly by Frydenberg’s statement that the government’s plans will:

…increase the total area of the reserves open to fishing from 64% to 80% … (and) make 97% of waters within 100 kilometres of the coast open for recreational fishing.

Building ocean resilience

Science shows that full protection creates resilience by supporting intact ecosystems. Fully protected green zones recover faster from flooding and coral bleaching, have reduced rates of disease, and fend off climate invaders more effectively than areas that are open to fishing.

Green zones also contribute indirectly to the blue economy. They help support fisheries and function as “nurseries” for fish larvae. For commercial fisheries, these sanctuaries are more important than ever in view of the declines in global catches since we hit “peak fish” in 1996.

Of course it is important to balance conservation with sustainable economic use of our oceans. Yet the government’s new draft plan leaves a huge majority of Australia’s waters open to business as usual. It’s a brave Emperor who thinks this will protect our oceans.

So let’s put some real clothes on the Emperor and create a network of marine protection that supports our blue economy and is backed by science.

A village in slow peril on the sea

The Guardian - Mon, 2017-07-24 14:30

Hallsands, South Devon New grass on old roofs, confusing ruined masonry with cliffs – this is what natural reclamation looks like


The sound is gulls, silence, the thin chatter of house martin chicks in lintel-nests. And the sea below, though at all tides it is a breathing, rather than a pervasive growl. By day you see Start Bay arcing many miles beneath the cliff. By night the lighthouse softly lights every sou’western-facing wall with a slow, silent rhythm.
Benign. But then, not. This coastline restlessly resists permanence, even on human clocks, and the sea that will be the end of this place. Again.
On a single night a century ago, Hallsands fell into the sea. The natural defences protecting the coast from winter storms had been pillaged and dredged for decades by industrialists: the shingle beach, the Skerries Bank. Pleadings from subsisting villagers were ignored or shushed. Then, on 26 January 1917, the waves clawed the village from the cliffs.

Surrey meadow slowly comes to life: Country diary 100 years ago

The Guardian - Mon, 2017-07-24 07:30

Originally published in the Manchester Guardian on 28 July 1917

SURREY, JULY 26
At daybreak this morning a white mist was so thick as to dim out the sight of the cattle in the meadow. They came lowing to the gate, waiting to be milked, and, passing through when it was open, were lost in the lane just as birds began to rustle in the hedge. Then the light spread and made the tall ragwort glisten – yellow colour seemed to shine everywhere. The stems of goatsbeard straightened, the fringes of nuts in clusters appeared of a new pale green, a farm boy clambered into the copse and came out whistling with a big bunch stuck in his button-hole, a pair of jackdaws flew noisily from an oak and went down to the village to search in the vegetable gardens.

Linear parks and the drive to ease congestion

The Guardian - Mon, 2017-07-24 06:30

If building new roads and fast traffic lanes does not cut traffic, can it work the other way round?

You would think that ending a traffic restriction would improve journey times, but the sudden termination of Jakarta’s high-occupancy vehicle (HOV) lanes had the opposite effect. To use these lanes drivers required two passengers, but a trade in hiring people bought the lanes to an abrupt end last year. The traffic could spread across all lanes, but journey times and congestion increased. In fact, traffic worsened over the whole network almost immediately. Even on roads with no HOV lanes, at times when the lanes had not operated, delays increased by up to two minutes per km. The US embassy measures air quality from its roof in Jakarta. It is too early to see the changes, but we can be sure that it did not get better.

On the tail of the uncommon lizard

The Guardian - Mon, 2017-07-24 06:30

They are widespread in the British Isles and could be found almost anywhere, but often aren’t, which is a bit of a mystery

The common lizard, Zootoca vivipara, is at its most numerous and active at this time of year. In late July it is giving birth to between three and 11 young at a time. They emerge from an egg sack that breaks during birth or immediately afterwards. That is why it is sometimes called viviparous lizard, meaning bearing live young, an unusual trait in reptiles.

Viviparous might be a better name in any case, as this lizard is not common at all in many places and some people may go for years without seeing one.

Hugs, drugs and choices: helping traumatised animals

The Conversation - Mon, 2017-07-24 06:09
Interspecies relationships can help traumatised animals form healthy attachments. Sugarshine animal sactuary, CC BY-SA

Rosie, like a real-life Babe, ran away from an organic piggery when she was only a few days old. She was found wandering in a car park, highly agitated, by a family who took her home and made her their live-in pet. However, after three months they could no longer keep her.

She was relocated to the Sugarshine animal sanctuary, outside Lismore in New South Wales. Kelly Nelder, Sugarshine’s founder and a mental health nurse, described her as “highly strung” and “needy”. It’s not surprising that Rosie, after the loss of two primary care attachments, was unable to bond with the other pigs; she was traumatised.

I met Rosie when I visited Sugarshine, investigating the similarities between human and animal trauma. I spent 20 years as a clinical and forensic psychologist, but as an undergraduate I studied zoology.

My zoology lecturers told us not to anthropomorphise – that is, not to project human qualities, intentions and emotions onto the animals we studied. But now there is a growing recognition of animals’ inner life and their experience of psychopathology, including trauma.

At Sugarshine, traumatised animals are given freedom to find solitude or company as they wish. Interspecies relationships are encouraged, like a baby goat being cared for by a male adult pig, or a rooster who sleeps alongside a goat.

Rosie has been at Sugarshine for a few months now and is more settled, roaming its gullies, farmyards and shelters, although according to Kelly she’s still anxious. She prefers the company of the bobby calves, wedging herself between them as they lie on the ground, getting skin-to-skin contact, falling asleep, and beginning the reattachment process.

I first made the connection between human and animal trauma on a visit to Possumwood Wildlife, a centre outside Canberra that rehabilitates injured kangaroos and abandoned joeys, wallabies and wombats. There I met its founders, economics professor Steve Garlick and his partner Dr Rosemary Austen, a GP.

When joeys were first brought into their care, Steve told me, they were “inconsolable” and “dying in our arms”, even while physically unharmed, with food and shelter available to them.

But this response made sense once they recognised the joey’s symptoms as reminiscent of post-traumatic stress disorder in humans: intrusive symptoms, avoidant behaviour, disturbed emotional states, heightened anxiety and hypervigilance.

Researchers at the University of Western Australia have developed non-invasive means for measuring stress and mood in animals and are now working with sheep farmers to improve the well-being of their animals. PTSD has been identified in elephants, dogs, chimpanzees and baboons, for example.

Safe, calm and caring

To rehabilitate from trauma, humans and animals need to feel safe and away from cues that trigger the individual’s threat response, deactivating the sympathetic nervous system (the fight-flight response). They also need a means of self-soothing, or to gain soothing from another, activating the parasympathetic nervous system (the rest, digest and calm response).

Progress, from then on, requires the development of a secure relationship with at least one other accepting and caring person or animal. Often, this “other” is someone new. In mammals, including us, this activates our affiliative system: our strong desire for close interpersonal relationships for safety, soothing and stability. We enter a calmer, receptive state of being so that the reattachment process can begin.

Possumwood uses three stages for trauma rehabilitation. Young animals are first kept in a dark, quiet environment indoors to reduce noises or sounds that might trigger their fight-flight response. Here they have the opportunity to develop new kin friendships of their own choosing.

Sedatives (Diazepam and Fluphenazine) are judiciously used in the early stages. Then, the principal carer spends as much time as possible feeding and caressing them to build a new bond.

Kangaroos are social animals, unable to survive in the wild unless part of a mob. So joeys are moved next to a large garage, and then finally to an outdoor yard, gradually being exposed to more kangaroos and creating social bonds. Once a mob grows to 30 or so healthy animals, they are released into the wild together.

The fundamentals are the same

The similarity between animal and human trauma is not surprising. Mammalian brains (birds also appear to experience trauma) share the principal architecture involved in experiencing trauma. The primates, and certainly humans, have a greater capacity for cognitive reflection, which in my clinical experience can be both a help and a hindrance.

My observations of trauma rehabilitation at Sugarshine and Possumwood emphasises the universal fundamentals:

  • A sense of agency (freedom and control over their choices)
  • To feel safe
  • To develop a trusting, caring bond with at least one other creature
  • Reintegration into the community at the trauma sufferer’s own discretion.

For those experiencing social isolation and shame around their trauma – such as returned soldiers or the victims of domestic violence – these principles could not be more pertinent. And for our non-human cousins, like Rosie, we would do well to remember that they do feel, and they do hurt.
