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.

The revolutionary technology allows wind power to be harvested in waters too deep for current turbines.

Tories urged to look at onshore windfarms which can be built as cheaply as gas plants and deliver the same power for half the cost of Hinkley Point, says Arup

Onshore windfarms could be built in the UK for the same cost as new gas power stations and would be nearly half as expensive as the Hinkley Point C nuclear plant, according to a leading engineering consultant.

Arup found that the technology has become so cheap that developers could deliver turbines for a guaranteed price of power so low that it would be effectively subsidy-free in terms of the impact on household energy bills.

Plans to bring the wild cats back to Northumberland have prompted concerns from farmers, but – from beavers to red kites – rewilding in the UK has generally been a success

More than a millennia has passed since lynx roamed Britain, and now the Lynx UK Trust – a community interest company formed in 2014 by conservationists and scientists – wants to reintroduce them into Kielder Forest in Northumberland. The trust’s plans have received opposition from the National Sheep Association, which says: “The consultation process adopted by Lynx UK Trust appears flawed and misleading.”

Robot spots suspected debris of melted fuel for first time since 2011 earthquake and tsunami destroyed the plant

Images captured by an underwater robot on Saturday showed massive deposits believed to be melted nuclear fuel covering the floor of a damaged reactor at Japan’s destroyed Fukushima nuclear plant.

The robot found large amounts of solidified lava-like rocks and lumps in layers as thick as 1m on the bottom inside a main structure called the pedestal that sits underneath the core inside the primary containment vessel of Fukushima’s Unit 3 reactor, said the plant’s operator, Tokyo Electric Power Co.

Comins Coch, Aberystwyth I was looking forward to seeing the ramshackle structure for myself. Then the anxiety began

A month or so ago, a friend casually mentioned that they thought red kites were starting to nest near their house. Very near, in fact; actually in the garden. Even in the hills beyond Tregaron, where kites wheel and dive in such abundance as to be almost unworthy of comment, having a nest within view of your kitchen window is unusual.

On the boundary of the property, the crook of a sycamore tree provided an apparently suitable spot for the pair to set up home; occasional bulletins told of the progress, albeit slow and halting, of nest building. It seemed the birds were in no great hurry – limiting their activity to the odd twig or two each day – but eventually they had assembled a slightly ramshackle structure that managed to support the weight of a sitting bird.

Gosh! How clever we have all become. Fifty years ago, only the top 2% of the population went to university and about 10% of them got firsts, so 0.2% of the population. Now, 30% go to uni, and 25% of them get firsts (Number of UK degree students receiving firsts soars, theguardian.com, 20 July), making 7.5% of the population. The universities say there is no grade inflation so we must be more than 30 times cleverer! Impressive or what?

Gove’s vision for the environment is undoubtedly ambitious but it is at odds with much government action – making it real will be a gargantuan task

Who knew? Environment secretary Michael Gove, arch Brexiter and seen just months ago grinning and thumbs up in eco-villain Donald Trump’s lair, turns out to be – in words, at least – a deep green.

His first major speech railed against “corporate greed and devil-take-the-hindmost individualism”, “extractive and exploitative political systems” and the “selfish agenda” of vested interests.
