Reputation?

Reputation?

The Australian Broadcasting Corporation, the ABC, holds a reputation. It is a highly respected media source down under, modeled not so loosely on the British Broadcasting Corporation. On taxpayer funds it provides Australians with news, entertainment and community service online, on radio and on TV.

It’s fair dinkum.

No surprise then that the ABC news app uploaded a post providing simple steps people can take to help koalas survive in their area. Just a small but useful morsel of public service information.

Here are the eight headline steps…

  1. Tell people koalas are going extinct
  2. Share social media posts
  3. Protect habitat
  4. Plant koala food trees
  5. Watch out for koalas in trouble
  6. Drive carefully and be vigilant
  7. Contain dogs
  8. Save 24-hour rescue hotline into your mobile

I am not sure what you think about this list.

Have a read of it again.

You may find it helpful and informative just as the ABC online editor no doubt hoped. Perhaps you are a fan of the furry and cute koala, so iconically Australian that stuffed toy versions outsell kangaroos in airport departure lounge shops.

But have you seen one in the wild?

Probably not. So the logic leap is that they are rare and, as the list tells us, going extinct. No doubt they need protection.

But there is a problem.

There is no evidence that koalas are going extinct. We don’t even know exactly how many there are in the wild so it’s impossible to know if the numbers are changing towards an extinction risk.

We do know that this species is widespread, cosmopolitan and does very well in favourable habitat containing younger woody plants. It can do so well that some local populations grow rapidly and become overabundant. We also know that the habitat koalas like exist in both agricultural and natural landscapes from Townsville to Mount Gambier, a latitudinal range of nearly 3,000 km.

We also know that when we have a good way to find them, sniffer dogs ironically, they pop up everywhere, often in places where they were either not known or have not been seen for a long time.

Folks, this critter is no more likely to go extinct than the Pope. There are plenty of places for it to hang on indefinitely.

So number one on the list is a lie.

Items 2, 3 and 4 on the list are, therefore, actions based on a lie. Now we are asked to do things that will cost us time and money because some people believe it’s right even though they present no evidence to justify such a request.

This should sound familiar, we see it in politics every day. Only in that forum we allow ourselves some leeway because we know the buggers are rarely honest, it’s why we invented democracy.

Now for a spoiler alert…

species go extinct

They always have.

An average mammal species is present in the fossil record for about 1 million years. There have been extinctions and mass extinctions throughout evolutionary history, some of them catastrophic, and almost all of them occurred before Homo sapiens even existed. And after each single or mass event, evolution continued to generate even more diversity. It’s what nature does.

So, get over it people. Species are an abstract concept, invented by us to help describe nature and how it works but mainly to satisfy our peculiar need to name and classify objects.

And then, for deep psychological reasons only Freud could begin to fathom, we assign a value to the object. Not the species you understand, the objects that make up the species.

This gives us items 5, 6, and 7 on the ABC’s list.

The objects in this case being specific individual koalas, that you or your canine companion (of a single species but with enough human selected natural variation in form and behaviour for a taxonomists to describe a Family or even an Order) might come across on your travels. Noting, of course, that most people will only see a koala in a zoo because they don’t take long walks in the bush staring up at the canopy.

What these ‘object-centered’ actions do ask is for us to be good citizens. People who are careful, aware of what’s going on around us and should we see distress, offer help. Nothing at all wrong with any of these. It’s just they should be a given. I would want to do this anyway for all objects, including other people, and I would want my kids to be vigilant too. It’s the biblical golden rule from Matthew 7:12 “Do unto others as you would have them do unto you“.

Item 8 on the list is, well, it’s blatant marketing.

A hotline? Come on ABC you are supposed to be the last bastion of the precommercial world where information is the currency, not profit or popularity.

The ‘simple steps’ in this list are just an opinion.

So sorry ABC, not fair dinkum, not fair dinkum at all.

Brumby

Brumby

Recently I sent an email to Professor David Watson, an ecologist at Charles Sturt University, who had just resigned from the NSW Threatened Species Scientific Committee.

I don’t know David although he is a fellow scientist, ecologist and peer of sorts. He resigned because the NSW Government passed the Kosciuszko Wild Horse Heritage Bill 2018 that gives protected status to feral horses, the brumby, a bill that not just goes against the Scientific Committee’s advice, it’s diametrically opposite to it.

Professor Watson’s resignation letter said he had better things to do with his time than provide advice that is ignored. Fair enough.

So my email was of support for an important personal decision by someone I don’t know and, for me, that is not something that happens every day.

So why reach out?

Well, the Committee had a draft determination to list wild horses as a Key Threatening Process. This means that there is sufficient scientific evidence that feral horses have a detrimental effect on native plants, animals and ecological communities, especially in alpine regions. In other words, horses are a degradation driver contributing to biodiversity loss.

Horses are like many other exotic species, they are not compatible with the objectives of protected areas. Instead, they make it much harder to protect native species because they are an unusual disturbance, one that the native plants and animals have not evolved alongside. In this instance grazing and hard-hooved trampling that alpine plants in Australia had not previously been subjected to in their recent evolution.

Think about this reality for a moment.

Everywhere that humans go they introduce species. Many of these introductions bring an evolutionary pressure not previously or at least recently present in the native communities of plants and animals. It changes the balance of evolutionary and ecological pressures. Some species benefit, for others, existence and reproduction can become more difficult. In time they are predated, eaten or competed out of the mix.

If the NSW Scientific Committee were looking at listing feral horses as a threatening process, this means there is enough research evidence that wild horses are doing this in NSW national parks, enough to see some native plants and animals at greater risk of extinction than before.

The bill, however, legislates for protection of wild horses. Passing the bill means NSW will have an Act to protect a key driver of biodiversity loss alongside a Biodiversity Act that is supposed to protect native plants and animals from the very same drivers.

It seems very odd to be so contrary, even for politicians. So why do it? It is politics of course.

Many of the wild horse in NSW occur in national parks in bellwether electorates. Seats that often swing hard at state and Federal elections and politics is sensitive just now, perhaps more so than for a while. NSW is about to enter an election, the Federal government has by-elections to worry about and is not long off its own visit to the polls. Then there is the more general turmoil around the world making a mockery of the neo-liberal political norms we have just gotten used to. The politics of horses becomes about those folk who like them for the frontier icon of rural solidity that, to many, they have always been. No matter that they trample a few native plants under-hoof. At this time the sensibility falls towards those folk with an Akubra and a whip and not the dreadlocked ones.

Unfortunately for Professor Watson, his understandable stand for sense over sensibility will only be a gesture, more important to him than anyone else. This is despite the fact that the government has just made a law to protect a driver of biodiversity loss.

It’s all desperate… and rather sad.


Positive future

Scenarios with pragmatic outcomes

Human beings continue to make illogical decisions that hasten the collapse of the natural world that supports us. Most of us die.

After several hundred years, with only a few million humans reduced to ancient style hunting, gathering and skirmishing, nature shows signs of recovery with greenery more verdant than before and wildness returning to the earth.

After a thousand years, the humans have settled into a less prolific growth cycle than before, perhaps learning from their own ancient history.

A new normal has emerged that allows evolution a bit more space to breath. New species evolve to fill the gaps left empty by the millions of species that humans eradicated.

Nature recovers from the sixth mass extinction just as it recovered from the previous five. It takes time of course, but that is nature.

Biodiversity and conservation are not the same thing

Biodiversity and conservation are not the same thing

Surprising as it may seem, biodiversity and conservation are not the same things. Most importantly biodiversity does not mean biological conservation.

Biodiversity does not mean rare or endangered either and it is not a synonym for an environmental value of your choice.

As the original international Biodiversity Convention agreed way back in 1992, the formal definition of biodiversity is

the variability among living organisms from all sources including, inter alia, terrestrial, marine and other aquatic ecosystems and the ecological complexes of which they are part; this includes diversity within species, between species and of ecosystems.

Rather than be so cumbersome, most biologists define biodiversity as the

totality of genes, species and ecosystems of a region

or more simply still, from the title of Ed Wilson’s 1992 book…

The Diversity of Life

though these definitions are very clear – biodiversity is about variety – the term has morphed in the eyes of the public and the media to mean conservation of rare things or just conservation, period.

This shameless hijacking of one technical term to mean something else in order to promote a specific agenda is all too common and I have lamented on this general topic many times before…

I even went on about it in Awkward News for Greenies and Missing Something

Lack of objectivity has become the bane of modern society that grows as each day of staring down at our devices passes, but I digress.

Not satisfied with pinching the term biodiversity for nefarious purposes, it would seem that another appropriation is afoot.

The technical term ‘natural resource management’, or more commonly the acronym NRM, is not familiar outside the cadre of land and environmental managers who work with the way nature can support a wide range of values that humans find useful, from production of food and fibre to clean water and a myriad of other ecosystem services.

There is no settled definition of NRM but this one would pass muster with most specialists…

the management of natural resources such as land, water, soil, plants and animals, with a particular focus on how management affects the quality of life for both present and future generations

NRM is about people and how they interact with landscape, the complex interplay between nature, production and values. Technically this makes it about land use and land use planning, land management, water management, biodiversity and biodiversity conservation, but also the many industries that are based on the production of food and fibre from fisheries to forestry. It is about understanding how the many complex values that people need landscapes to deliver can be realised, even maximised, now and into the future.

In short, NRM is applied ecology.

Lately I have noticed a lot of definition creep with this term. More and more it is being used to mean the environmental value of conservation, especially the protection of remnant native vegetation.

In many landscapes developed for agriculture, remnants of native vegetation are small, isolated and infrequent, often increasingly so as production takes precedence. Remnants are perceived to be where the rare and endangered hang out, the last places where conservation values can be found. Through this association remnants of native vegetation have, for many people, grown in value and importance. Many NRM decisions have become about how to protect these patches and control the drivers, especially  weeds and pests, that degrade them.

In a few short steps, this focus on native vegetation as being NRM, makes it a simple surrogate for saving species.

NRM = conservation.

Some people feel good about this appropriation. After all they are in the minority and need all the tools at their disposal to protect the conservation values that they hold dear. In a way it is important that they do this for the majority of people are staring down at their phones blissfully unaware and unconcerned that biodiversity is crashing down around us. Somebody has to hold the torch.

The problem I have is that NRM is supposed to be a holistic concept, one that considers all values at the same time and tries to understand the consequences of resource use decisions for all of them. This requires great technical breadth, a moderate mindset, and a pragmatic view of the human landscape interaction.

Almost by definition, this is not how the conservation-minded think.

If this trend for ‘NRM = conservation’ continues it would be a great shame. NRM should be about the challenging decisions needed to balance resource use for multiple outcomes. We have to grow food and fibre but it makes so much more sense if we do this without destroying other environmental values.

But if NRM becomes yet another synonym for conservation, then immediately there is a bias away from achieving a balance of values at sites and across the landscape in favour of conservation.

 

Positive future

Scenarios with pragmatic outcomes

Natural resource management becomes the dominant paradigm in rural landscapes.

Every land management decision is made with knowledge of the implications from resource use trade-offs, with the overall objective of achieving long-term balance in all values – utility and preservation.

Native vegetation is cleared only when it enhances production values and as a last resort after all other options for production efficiency on existing agricultural land are exhausted or where there is likely to be excess of environmental value that is easily recovered through restoration or rehabilitation. Even then any clearing is compensated with an increase in management actions that enhance either production efficiency or landscape health.

Resource conversion becomes governed by understanding value trade-offs and the implications for current and future ecosystem performance. There is no need for heavy regulation because everyone understands that to follow smart NRM decisions is the only way to maintain and enhance all values.

There is also no need to hijack the term NRM because everyone knows what it means.

Values again

Values again

What do you value most?

Your loved ones, your health, Sheba the cat, your favourite cashmere jumper or even, perhaps, your screen time.

If you think about it, even for a moment, lots of things are likely to be on your list of valuables.

Alloporus has discussed this kind of thing before. And in thinking about how we perceive value, concluded that value is always relative and personal.

The question here is how far down the list of things we value is nature?

You know, all the plants, animals, hills and streams, the flowers that bloom and bees that buzz, the cute and the cuddly, and even the icky bugs and slugs, together with all the vitality that they bring.

I side with’ is a website aimed at increasing voter engagement in issues of the day. It’s ‘popular issues’ page lists 100 most popular issues filtered from, they claim, a million unique survey answers per day.

When I had a look at the site a few months ago, just 8% of the issues listed were nominally about the environment and none were directly about nature (note that this is an active polling site, so the current lists may differ substantively).

‘Environmental regulation’ makes the front page but you have to scroll down to find ‘mining water use’, and further still to ‘foreign land ownership’, ‘plastic product ban’, and ‘nuclear energy’. Way down the list we get ‘whaling’, ‘fracking’, ‘GMO foods’, ‘coal seam gas’, and ‘nuclear waste’.

More popular than environmental regulation when I looked were equal pay, gay marriage, abortion, mandatory vaccinations, terrorist citizenship, LGBT adoption rights, and welfare drug testing.

Let’s just pause a moment for this to sink in.

Nature, the cornucopia of organisms, services and wonder that gives us clean air, fresh water, food, and any number of raw materials that collectively provide us with the opportunity to contemplate values, does not make the list of 100 most popular issues of the day.

This is not an isolated finding.

Nature languishes way down on many lists of environmental issues even though aspects of nature are implicit in so many of our most acute challenges, not least in providing solutions.

Somewhere along the way we have become so disconnected from what nature does for us that we do not even think it is important.

This is quite remarkable.

I’m going to give in to my incredulity and harp on this one.

Our collective term for the very thing that sustains us, the place we evolved into and shaped our characters, beliefs and our psyche, is not even on our intellectual or moral radar.

Let’s just consider one of the things that happens in nature each and every moment of every day and what would happen if it stopped.

Decomposition is the process by which complex organic material is broken down into its constituent parts. These chemicals become available for recycling by plants back into organic matter or, if you like, food for heterotrophs including people. Bacteria, fungi and a host of invertebrates in soil and leaf litter are responsible for this natural process that only keen gardeners and farmers are likely to notice.

What if decomposition stopped? In a short time we would be knee deep in dead things. None of the carcasses would smell of course because the process of decomposition releases the odorous gases of decay. Instead they would just pile up along with the dead plant material.

In dry periods the most likely outcome would be fire. A sobering proposition given the heavy fuel load of dry biomass.

But this is not the half of it.

Without nutrients there are no building blocks for plants. Once the burst from nutrient stored in the seed is over, seedlings would simply stop growing. Deciduous trees would not flush and evergreen plants would become dormant.

Photosynthesis would shut down and oxygen production would slow to a halt. Oxygen deficits would compete with starvation as the means to kill off all the animals.

In just a few months most of nature would be changed forever. Humanity would not survive.

Of course this is not going to happen because it is impossible to stop decomposition. Bacteria and fungi are way too pervasive for that.

And maybe this is it.

We believe that nature is unbreakable. It has so much built in resilience and redundancy we see it as a perpetual motion machine that can never stop.

But human actions can slow nature down by drying out soil, changing vegetation, over-exploiting the soil nutrients, reducing soil organic matter or through pollution.

Our actions also channel nature into delivering the products we need. Nature becomes fields, farms, plantations and reservoirs. Places where we convert nature into commodities. This reduces overall redundancy and resilience because so much of the energy and nutrient flows are directed into things that humans need.

We value these things of course, only not in quite the same way as we value nature. Commodities are literally valuable because we convert them into cash. Land is valuable because it can be used to generate commodities. Soon we are down with the dollar.

The reality is that the economic focus is with us, stuck like araldite to our present and future. There is no credible alternative or, more significantly, no credible way to transition to an alternative, that can give us back a focus on nature without looking through a commercial lens.

So, for now at least, we do not value nature. It’s not on our radar and that is a big problem.


Positive future

Scenarios with pragmatic outcomes

The global wheat crop is decimated by a fungal disease that is immune to all attempts to control it. After three years of next to no wheat anywhere, there is a food crisis that affects everyone, even those who shop for their food in supermarkets. No bread, no pasta, no cake and no wheat beer. All the gluten free alternatives are consumed by the rich.

In a remote part of Australia, an organic farmer called Bruce is the only producer still growing wheat. His crops remained healthy even after all his neighbours went out of business. Soon he was spending way to much time describing his methods to a succession of scientists and media. The world got into the way Bruce did things, his pasture cropping approach, his decades long attention to building soil carbon and his attention to slowing down runoff all across his landholding.

Bruce became a new kind of celebrity. He was world famous as the saviour of bread but he stayed calm and matter of fact about it all. He kept growing wheat even when there were many other easier and more lucrative options.

What did happen that nobody expected was that his style and his humility touched people. What was happening on his paddocks went viral. Everyone became aware of how important it was to grow food with empathy for nature.

Instead of ignorance and apathy people paid attention to where their food came from. They asked questions about how food was grown. Did the farmer do it like Bruce? They paid realistic prices for produce because it was obvious that cheap meant mining the nutrients and water out of the system just to break even. It was a tsunami of change.

The wheat cropping system recovered but the health benefits of going without wheat meant that most consumers stayed with alternatives.

What happened though was that organic became mainstream because everyone now knew it was about carbon and not yoga and dreadlocks.

Insects

Insects

All around the world there are entomologists, people who study insects. We should be very proud of these fine folk for without their understanding it would be harder to manage many diseases transmitted by insects, resolve many pathogens, figure out how to assist insects pollinate crops and, most importantly, support insects and their invertebrate cousins maintain soil fertility.

Then there are insect people you might know about. The pest control folk who make sure the fly spray kills the flies and not us.

Sounding a bit posh and, dare we say a little ivory tower, ‘entomologist’ usually refers to the researchers who gather the data and sift through it to find evidence for the good, bad and ugly on the insects that share our spaces. So we can listen to them with some confidence. Not only are they spending their days with ‘bugs’, yuck, they are also the right kind of skeptic using the numbers to find inference.

Lately the number of insects observed by entomologists are in decline. This is not because the entomologists are getting lazy, spending more time watching TV than setting malaise traps or peering down microscopes, but because there are fewer insects around to be studied.

A recent publication confirmed from long-term trapping data in 63 German nature reserves, what many have casually observed in many parts of the world. Insect numbers are going down. And not just by a little bit, they are plummeting.

Hallmann C.A., Sorg M., Jongejans E., Siepel H., Hofland N., Schwan H., Stenmans W., Müller A., Sumser H., Hörren T., Goulson D., de Kroon H. (2017) More than 75% decline over 27 years in total flying insect biomass in protected areas. PLoS ONE, 12(10), eo185809

Three quarters in a generation.

If such a collapse had happened to the Dow Jones the sky would have fallen in. Imagine trying to survive on a quarter of your wages you earned when you started out. Heaven forbid if the defence budget from the 1990s was reduced by all those billions, how scared and vulnerable would we feel?

“Not a problem” the observant reader cries out. “The crawling insects will simply fill the space left by the loss of the flying ones, that’s what you ecology types tell us all the time.”

Perhaps.

Equally a loss in numbers does not necessarily mean a loss of function. Pollination only needs one bee to transfer pollen from stamen to stigma. Fewer mosquitos has to be a good thing and those beetle larvae can’t be doing that much to soil when we have fertilisers.

It is always very easy to play the ostrich. Only they are remarkable and very dumb birds.

When an observation so dramatic and material to so many key ecological processes becomes known we dismiss it at our peril. If we ignore these numbers just because we like the idea of fewer midges at summer evening picnics without looking deeper to find out what is going on, we increase risk to our already precarious food security.

We need to enable our entomologists to find out why the numbers went down and if the decline is going to affect the key ecosystem services we rely on.

Or, of course, we could ignore them and buy more submarines.

Tuppence a bag

Tuppence a bag

Should you feed the birds?

Well, they are wild animals, more than capable of feeding themselves.

Of course, if they fly around and don’t find food they go hungry. If this foraging fail continues for too long they either starve or are too weak to nest and rear chicks. Those that find enough food pass their genes on into the next generation – bog standard natural selection.

The presence of my house and suburb is, of course, a huge disturbance to the natural habitat. It alters the outcome of natural selection drastically favouring those species that like what houses and gardens offer over the resources available in the bush that was there for millennia before westerners.

Feeding the birds is only a tiny blip in this dramatic habitat change. Trees and shrubs to paved roads and gardens is way more important than a few seeds or apple cores on a bird table. Throw in an Indian or a noisy myna bird that come along with the houses and, well, feed all you like, the aggressive mynas will still be there to chase the passerines away.

Feeding the birds is only ever going to affect wild birds at the margins. In time of extreme heat, cold or drought it might keep a few specimens alive a little longer, enough to get through, but this would be the exception not the rule.

So, the reason to feed them is for my benefit.

I get to see them up close and squabble amongst themselves on the feeder. The pecking order between and amongst the species is a fascination as is their choice of the morsels offered. There can be half a dozen brightly coloured specimens parading at any one time. It is quite a sight.

Then the sulphur crested cockatoos glide in and spoil the party. They are big, brash and more than capable of taking a chunk out of the hardwood balustrade when they get bored. I sometimes chase them off which is bizarre given I got them to come over in the first place.

And if I forget to put out a fresh supply of ‘wild bird seed’ the cheeky buggers line up on the outdoor furniture, peering into the house at any movement with a chirp and a forlorn look.

In a pique I refuse to replenish the supply. After a few days the lineup dwindles to nothing and normality is restored until, in a moment of weakness, I put some seeds out again to repeat the cycle.

Yes, it’s OK to feed wild birds in your garden – so long as it’s the right food

As you probably gathered I live in Australia. There are conservation minded folk here who dislike, even detest, my bird feeding behaviour. That I should feed birds at all is bad enough, that I do so intermittently borders on the criminal. Wild should be wild they say. What right do I have to cause obesity in lorikeets by feeding them the wrong seeds?

Instead all I need to do is plant some wild bird friendly plants in my garden and enjoy the wild birds from a distance.

Only here is the thing.

Those aforementioned noisy mynas arrived in our yard about 5 years ago. They took up residence en mass and now patrol the airspace chasing away everything but the butcherbird, the kookaburras and the cockatoos. All the smaller species, the treecreepers, whistlers, wagtails, scrubwrens, and the like that I used to marvel at from my office window are nowhere to be seen or heard. They have retreated to safer habitat.

If I planted, it would be like trying to win a battle on the ground without first dealing with superiority in the air. Any bird trying for a feed at the bottlebrush blossom would just be hounded away before they took a sip.

It is actually rather sad. There was once a wonderful distraction when I glanced up from my computer screen toward the gum trees. But not any more.

The only hope is that we have a drought. For then the garden might be attractive enough for more species to brave the myna harassment long enough for me to view them again.

Meantime I will make do with feeding the bigger birds and not feel guilty because the damage is already done by me. Not because I feed the birds, but because I chose to live in a suburb carved out of the bush.

Incredulous

Here is a recent headline from an ABC online article, a reputable publicly funded media source

Bush stone-curlews popping up in suburbs as bird once extinct in ACT makes a comeback

Nice you might think given that headlines containing good news are like threatened species themselves, rare and at risk of being lost forever.

Here is the problem.

The IUCN lists the conservation status of the Bush stone-curlew as “least concern”. In other words, its not under any immediate threat of extinction in the wild.

In fact, the species has a broad habitat preference throughout Australia pitching up in open forest, eucalyptus woodland, rainforest edges, grassy plains, arid scrubland and along inland watercourses across much of the vast continent. It is a common species in the cities of Brisbane, Cairns and Townsville and is abundant in the tropical and subtropical north. In other words, it’s not a rare species at all.

I’m told there are pubs up north where you can sup on a stubbie alongside a foraging stone-curlew.

To use the word extinction, the termination of a lineage, where the moment of extinction is generally considered to be the death of the last individual of the species, is a lie.

This bird is not extinct.

Placing a geographic limit so as to use the term is disingenuous. Strippers are extinct in the Vatican is about as crazy a statement.

So is this fake news?

I think it is. The bird species is not actually extinct. It’s not even at risk unless you specify a discrete subset of its natural range. And when we learn that the Canberra specimens were almost certainly taking a wander from a nearby reserve artificially stocked with a few pairs to “reintroduce” them to the local scene, then the implicit hope in the story takes a huge dive.

I know that there are feeds to feed in this modern age of lightning fast news cycles. And I also know that there are good reasons for at least trying to be upbeat when, for the conservation minded, the world appears to be crashing down. But, like cricketers crossing the line, there are consequences for cheating on the truth. In the end people do not respect you, they dismiss everything you say even when you are actually being honest.

So my call to myself, and everyone who is in the business of information, let’s be as honest and as truthful as we possibly can and leave the spin alone when it comes to the facts.

This is easy to say and not at all easy to do but we all have to try.
