GUEST OBSERVER
Legislation designed to protect wildlife is being rolled back or ignored in all sorts of ways in all sorts of places, according to a new global database of attacks on green tape.
When President Donald Trump was mulling over whether to pull out of the Paris climate agreement, it is hard to imagine that he was listening to the experts. US climate researchers are being so stifled, ignored or blackballed that France has now offered sanctuary to these misunderstood souls.
One might prefer to think of Trump as an outlier in an otherwise environmentally sane world. But alarmingly, there’s just too much evidence to the contrary.
A recent analysis, led by Guillaume Chapron of Sweden’s Agricultural University, reveals a rising tide of assaults on environmental safeguards worldwide. If nothing else, it illustrates the sheer range and creativity of tactics used by those who seek to profit at the expense of nature.
The assaults on environmental protections are so diverse that Chapron and his colleagues had to devise a new “taxonomy” to categorise them all. They have even set up a public database to track these efforts, giving us a laundry list of environmental rollbacks from around the world.
One might perhaps hope that species staring extinction in the face would be afforded special protection. Not in the western US states of Idaho and Montana, where endangered gray wolves have been taken off the endangered species list, meaning they can be shot if they stray outside designated wilderness or management areas.
In Western Australia, an endangered species can be legally driven to extinction if the state’s environment minister orders it and parliament approves.
Think diverse ecosystems are important? In Canada, not so much. There, native fish species with no economic, recreational or indigenous value don’t get any legal protection from harm.
And in France – a crucial flyway for Eurasian and African birds – killing migratory birds is technically illegal. But migrating birds could be shot out of the sky anyway because the environment minister ordered a delay in the law’s enforcement.
In South Africa, the environment minister formerly had authority to limit environmental damage and oversee ecological restoration at the nation’s many mining sites. But that power has now been handed over to the mining minister, raising fears of conflict between industry and environmental interests.
In Brazil, the famous Forest Code that has helped to reduce deforestation rates in the Amazon has been seriously watered down. Safeguards for forests along waterways and on hillsides have been weakened, and landowners who illegally fell forests no longer need to replant them.
In the Indian Ocean island nation of Mauritius, endangered species are protected by law, unless it is deemed to be in the “national interest” not to do so. Although an endangered species, the endemic Mauritius flying fox was annoying commercial fruit farmers, so the government has allowed more than 40,000 flying foxes to be culled.
And in Indonesia, it’s illegal to carry out destructive open-pit mining in protected forest areas. But aggressive mining firms are forcing the government to let them break the law anyway, or else face spending public money on legal battles.
<h2>Shoot the messengers</h2>
Campaigners should also beware. Under new legislation proposed in the UK, conservation groups that lose lawsuits will be hit with heavy financial penalties.
In many parts of the world, those who criticise environmentally destructive corporations are getting hit with so-called “strategic lawsuits against public participation”, or SLAPP suits.
In Peru, for instance, a corporation that was mowing down native rainforest to grow “sustainable” cacao for chocolate routinely used lawsuits and legal threats to intimidate critics.
That’s before we’ve even discussed climate change, which you might not be allowed to do in the US anyway. Proposed legislation would prohibit the government from considering climate change as a threat to any species. No wonder researchers want to move overseas.
As the above examples show, essential environmental safeguards are being conveniently downsized, diminished, ignored or swept under the carpet all over the world.
Viewed in isolation, each of these actions might be rationalised or defended – a small compromise made in the name of progress, jobs or the economy. But in a natural world threatened with “death by a thousand cuts”, no single wound can be judged in isolation.
Without our hard-won environmental protections, we would all already be breathing polluted air, drinking befouled water, and living in a world with much less wildlife.

Around the world, environmental laws are under attack in all sorts of way: Bill Laurance

GUEST OBSERVER
During summer, when a rainbow lorikeet or kookaburra visited your home, what did you do? Did you offer them a slice of apple, or simply watch until they take flight?
It brings many people joy to provide food and water for birds, to encourage them to stay a while and be given the chance to observe them more closely. But some people are reluctant to interact with birds in this way because they’re worried it might damage the birds’ health. 
In contrast with other countries, little research has been done on the effects of feeding birds in Australia. As a result, there are no established guidelines around how to feed and provide water for local birds. 
That’s why we ran the Australian Bird Feeding and Watering Study. We asked nearly 3,000 people to monitor the birds that visited their feeding areas and birdbaths. We wanted to know if there was a difference in the species that visited different types of gardens.
We examined the numbers and types of birds visiting:
<ul>
<li>birdbaths where no food was provided</li>
<li>birdbaths where food was provided</li>
<li>bird-feeders where birdbaths were provided</li>
<li>places where only food was provided.</li>
</ul>
The early results from the winter stage of the Australian Bird Feeding and Watering Study suggest that if you provide food and water, you will get more birds in your garden. But the species you attract will depend on what exactly your garden has to offer. 
Granivores
Granivores are seed-eating birds. They include species such as parrots, crested pigeons, sulphur-crested cockatoos, crimson rosellas and galahs. 
We noticed a spike in the number of granivores in gardens where both food and birdbaths were provided. But when food was on offer, fewer granivores chose to use the birdbath. We don’t yet know exactly why this is, but it could be because these seed-eaters need less water, or they can get it more easily from other sources than they can food.
Also, most of the bird food sold in shops is seed-based. People who buy these products will naturally attract more seed-eating birds to their garden.
We were, however, surprised to see crested pigeons visiting gardens where food was provided. These birds are only recent urban arrivals, and were previously restricted to semi-arid environments as opposed to the more urban areas where most of our citizen scientists lived. But crested pigeons are very adaptable and now compete fiercely for food and territory with the introduced spotted dove in some Australian gardens.
<h2>Nectarivores</h2>
“Small” nectarivores are nectar-eating birds that weigh less than 20 grams. The main birds in this group are New Holland honeyeaters, eastern spinebills and Lewin’s honeyeaters. 
The early results of our study suggest small nectarivores prefer gardens with birdbaths more than their granivore and insectivore friends. In fact, it seems that these small nectarivores like birdbaths so much, they will choose birdbaths over food when both are provided. 
“Large” nectarivores are nectar-eating birds that weigh more than 20 grams. These species including noisy miners, rainbow lorikeets and red wattlebirds – seem to prioritise food over birdbaths. This may be because they’re looking for a source of protein that they can’t easily find in their natural environment. 
Honeyeaters – such as Lewin’s honeyeaters, blue-faced honeyeaters and noisy miners – will forage on nectar but will eat insects as well. They switch from one to the other, but once they have found their meal they will defend it vigorously from other birds. 
<h2>Insectivores</h2>
Insectivores feed on insects, worms, and other invertebrates. Some insectivore species include superb fairy-wrens, willie wagtails and grey fantails.
Insectivores are most attracted to gardens where both food and water are provided. While superb fairy-wrens were frequently found in gardens where food was provided, willie wagtails and grey fantails preferred to visit gardens where only water is provided. 
<h4> </h4>
Many people have told me how confident fairy-wrens and willie wagtails can become around houses and gardens. These tiny birds can be bold and aggressive, and can work together to get what they want. A mum and dad fairy-wrens will conscript their older children into looking after younger ones – and siblings who refuse to help find food and defend territory may even be kicked out of the family. So these tough breeds have a competitive advantage in their new urban environments, and aren’t afraid to mix with or even chase off bigger birds.
You may be wondering exactly what type of seed to put out to attract which granivore, or which meat attracts a carnivore like a Kookaburra. I’m afraid we can’t yet say for sure, as we are yet to analyse the data on this question. Watch this space.
<h2>Could birds become reliant on humans for food?</h2>
Many people worry that birds will become reliant on humans to provide food for them. But this mightn’t be as big a concern as we once though.
The birds turning up at feeding areas and birdbaths are species that are highly adaptable. Many Australian birds live long lives, and relatively large brains when compared to their European counterparts. Some experts have argued that some Australian birds have evolved a larger brain to cope with feast and famine conditions in the Australian environment.
<h4> </h4>
Many Australian bird species can switch easily between estates and gardens in one area, be semi-nomadic, fully nomadic or seasonally migratory. This ability to adapt and switch between diets makes Australian bird species very resourceful, innovative and adaptable. 
Of course, Australia also has birds that have highly specialised diets or habitats, and they’re the ones usually most threatened or limited to one territory – birds like the regent honeyeater or ground parrot. In this study, we’re concentrating on birds that are adapting to urban areas and turning up at birdbaths and feeding areas in gardens. 
<h2>Building our knowledge of bird feeding behaviour</h2>
We plan to develop guidelines around providing food and water for birds in a way that has the highest conservation value for our feathered friends. But before we can do that, we need more data from you. 
So please take part in the summer stage of the study and pass the word around to others who may wish to be involved.
The summer survey will run for four weeks, beginning on January 30 2017. Visit feedingbirds.org.auto download the complete report on our early findings or to register to take part in our summer study.
