Rice fields support the global stronghold for an endangered waterbird

Posted on: August 5th, 2019 by Matt Herring No Comments

 

Here’s an article from The Conversation about my new paper in Agriculture, Ecosystems and Environment:

Meet the endangered Bunyip bird living in Australia’s rice paddies

Endangered species are living happily in rice fields.

The debate around the Murray-Darling Basin is often sharply polarised: irrigation is destroying the environment, or water reforms are ruining farming communities.

But there is another story. In the Riverina region of southern New South Wales, a strange waterbird is using rice fields to live in and breed.

The endangered Bunyip Bird, also called the Australasian Bittern, is famous for its deep booming call – for thousands of years thought to be the sound made by the mythical Bunyip.

It’s a sound now familiar to most rice growers. In 2012, Birdlife Australia and the Ricegrowers’ Association teamed up to learn more about bitterns in rice. The total bittern population, including New Zealand and New Caledonia, is estimated at no more than 2,500 adults.

Why a wetland might not be wet


The first question was how many bitterns are using rice crops. After surveying the birds on randomly selected farms, we crunched the numbers. Our results, just published, are staggering.

Across the Riverina, we conservatively estimate these rice crops attract 500-1,000 bitterns during the breeding season, about 40% of global population. It turns out the way rice is grown provides ideal water depths and vegetation heights for bitterns. It’s also favourable for their prey: frogs and tadpoles, fish and yabbies.

There is a growing body of global research investigating how human-made habitats can help fill the gap left by our vanishing wetlands, from ditches for rare turtles to constructed ponds for threatened amphibians. Rice fields around the world show great promise as well, with various “wildlife-friendly” farming initiatives. In California, farmers re-flood harvested fields to support thousands of migratory shorebirds and waterfowl, while in Japan consumers pay a premium for “Stork Rice” to help endangered species.

For the first time we’ve looked at every threatened bird in Australia side-by-side


However, rice fields are no substitute for natural wetlands, and it’s now clear both play a crucial role in sustaining the bittern population.

Satellite tracking has shown us that at harvest time bitterns disperse to some of southeastern Australia’s most important wetlands, including the Barmah-Millewa system along the Murray River, Coomonderry Swamp near Shoalhaven Heads in New South Wales, Pick Swamp in South Australia, and Tootgarook Swamp on the Mornington Peninsula near Melbourne.

Water efficiency might be bad news for the bittern

Rice farming in Australia’s Riverina has a century-long history. The amount grown varies greatly from year to year, depending on water allocations, and ranged from 5,000-113,000 hectares over the past decade. Around 80% is exported and it provides food for up to 20 million people each year.

Driven by water efficiency, many rice growers in the Riverina are switching their methods to intermittent flooding and not “ponding” the water – maintaining inundated fields – until later in the season.

A shorter ponding period will likely reduce opportunities for the bitterns to breed successfully before harvest. Another threat to bitterns is farmers switching to alternative crops and horticulture, none of which provides them habitat.

Around 40% of the global Australasian bittern population come to the Riverina’s rice fields.
Matt Herring, Author provided

During the 2017-18 irrigation season, there was more cotton grown than rice for the first time in the Riverina. It’s usually simple economics: irrigators will generally grow whatever gives them the best return per megalitre of water, with their choice having no net effect on the overall amount of irrigation water used in the system.

Water management in the Murray-Darling Basin is complicated, with fluctuating temporary water prices and trading between catchments. Water is allocated to either agriculture or the environment, setting up a dichotomy. But we think allocations to serve a single purpose may be overly simplistic, and the way bitterns use rice offers a case study for considering multi-purpose water use.

Working closely with growers, we are identifying ways to develop cost-effective incentive programs for bittern-friendly rice growing, where a sufficient ponding period is provided, with complementary habitat on banks, in crop edges and adjacent constructed wetland refuges. The aim is to boost the bittern population with the help of rice farmers.

Bitterns can nest and feed in rice paddies, but they depend on fields being flooded.
Matt Herring, Author provided

We are also surveying consumers about their attitudes towards bittern-friendly rice. Would you pay a premium for rice products that offset additional costs to growers for bittern conservation? How do you feel about adjusting water and conservation policies?

Protecting the world’s wetlands: 5 essential reads


Bitterns are not the only threatened species that use the Riverina’s rice fields. The endangered Southern Bell Frog and Australian Painted Snipe have also adapted to rice crops, and it’s likely there are significant populations of other species too.

With 61% of Australia managed by farmers, the need to incorporate wildlife conservation on farms has never been greater. We hope our work will help address the divisive, sometimes toxic debate around water use in the Murray-Darling Basin, uniting irrigators and environmentalists.The Conversation

Wah Wah Wetland Management Guides

Posted on: June 26th, 2016 by Matt Herring No Comments
In the Wah Wah region, north of Hay, major changes to how stock and domestic water is delivered are underway. To generate water savings, channels and ground tanks are being replaced with pipelines and troughs. Since 2011, Murray Wildlife and Murrumbidgee Landcare have been working closely with local landholders to address their concerns about the loss of habitat associated with the replacement of the old system. The focus has been on the ground tanks but the region also contains significant natural wetlands. Thanks to a $9000 grant from the Norman Wettenhall Foundation, five management guides have been developed for some of the most important Wah Wah wetlands.
These management guides have been developed by the landholders, in conjunction with Wildlife Ecologist Matt Herring, as a key first step in facilitating positive future actions. They highlight the significance of each site and incorporate a range of ideas to benefit wildlife and native vegetation, from the removal of impediments to flow and delivery of environmental water, to fencing for grazing management and weed control programs. A field day showcasing the proposed works is being planned for later this year.

Paddock Tree Film In Production

Posted on: December 29th, 2015 by Matt Herring No Comments

 

We’re very pleased to be producing a new short film with Murrumbidgee Landcare, thanks to funding from the NSW Environmental Trust. It’s all about paddock trees; their values and the issues they’re facing. It showcases some of the great work landholders are doing to stem the tide of paddock tree loss in rural landscapes. We’re working with Nathan James Productions who helped us produce Farm Dam Blitz.

Recently, we were out near Goolgowi, north of Hay, and were thrilled to get footage of nesting Major Mitchell Cockatoos. They were in a big, old Belah. The footage will be a great addition to the film, which includes a ‘behind-the-scenes’ / ‘the-making-of’ component; a comedy of errors perhaps. The film will be launched in 2016. Stay tuned …

Reimagining Rice Farms: Yielding Bunyip Birds & More

Posted on: April 8th, 2015 by Matt Herring 1 Comment

 

Matt Herring

*This article was first published by the Cumberland Bird Observers Club in February 2015.

The marriage of farming and wildlife conservation is as captivating as it is necessary. It’s what drives the Bitterns in Rice Project, now in its third season, and it was a key motivation behind the humbling support we received during the Tracking Bunyip Birds campaign in spring last year.

The Australasian Bittern is one of our country’s most threatened birds. They are considered nationally and globally Endangered, perhaps with just two or three thousand remaining. They are also among our most poorly known bird species. The association between the legendary Bunyip and the booming call of breeding males is no coincidence. The sneakiness and near-mythical nature of the species was perhaps best illustrated in 2012 when John Weigel broke the national birding record, held for a decade by Sean Dooley. He travelled extensively and found a whopping 745 species, but he did not find a Bunyip Bird.

IMG_3282 - Version 2            IMG_3199

A trip to the rice crops of the NSW Riverina would have produced the goods. For decades we’ve known that bitterns use these rice crops, yet only now as a result of extensive surveying are we beginning to appreciate the significance of the population. We continue to crunch the numbers and expand our surveys of randomly selected rice farms, but it’s evident that in most rice growing seasons a population of somewhere between 500 and 1000 descend on the rice in late spring, approximately two months after sowing. We’ve also learned that there is widespread breeding. Encouragingly, from the nests found so far, it appears that there is sufficient time for the chicks to fledge before harvest, which normally peaks around April.

I’ve been chasing bitterns in wetlands across the Riverina since the late 1990s and I’m still coming to grips with the fact that my best results by far have come from agricultural wetlands; completely constructed habitats that produce food and support an impressive biodiversity. I wouldn’t be nearly as excited about the prospect of farming and wildlife conservation working together here if it involved just this one species. However, it doesn’t take much surveying of Riverina rice fields to realise their value for others. Notably, Glossy Ibis and Whiskered Tern occur in their tens of thousands. More familiar waterbirds, such as White-necked Herons and Pacific Black Ducks, are there in big numbers too. Less obvious are the populations of Baillon’s Crakes and Golden-headed Cisticolas, again extending well into the thousands. There are migratory shorebirds like the Sharp-tailed Sandpiper and Latham’s Snipe that also make widespread use of rice fields.

Probably of most interest to birders are the Eastern Grass Owls that we documented roosting in rice crops last season. There were at least five of them. Previously only expected in the north-east of the state, subsequent anecdotes from rice growers suggest these owls may have also been overlooked in rice crops until now. I’m certainly hoping to turn up some more this season. Funnily enough, one was found roosting within metres of a bittern nest and I feared the worst: bittern chicks on the menu. Fortunately, I needn’t have worried, with two ~18 day old chicks relocated on a bank, already 50 metres from the nest. Beyond waterbirds, and speaking of threatened species eating each other, rice crops in parts of the Riverina, such as Coleambally and Wakool, support significant populations of the nationally Vulnerable Southern Bell Frog (also known as the Growling Grass Frog). Peter Menkhorst watched an Australasian Bittern eat 17 of them at Werribee so it’s a reasonable assumption that they’re an important food source for bitterns in some rice crops.

IMG_7564 - Version 2          Australian Painted Snipe in fligth over rice field MHERRING          Australian Painted Snipe in flight over rice field MHERRING

Perhaps just as surprising as the owls has been the use of rice fields by the Australian Painted Snipe (APS), our only other waterbird species considered Endangered at the national and global level. For wader enthusiasts and others interested in more detail, see the forthcoming issue of The Stilt. In a nutshell though, during the 2012-2013 rice season, a total of 87 APS were recorded at eight widely distributed Riverina rice fields. It’s highly likely that they were indicative of many more, probably at least several hundred, because of the limited survey effort and coverage.

So on top of the largest known population of the endangered Australasian Bittern, it’s easy to see the potential for agriculture and conservation – two traditionally separate schools of thought – to work together here. Protected areas like national parks, and the most intact parts of the landscape are vital to conservation, but it’s clearer than ever that alone they’ll be vastly inadequate in waving off the forecast extinctions. The challenges ahead are enormous, and with about 200 000 extra mouths to feed each day on our pale blue dot, population growth and food security are good places to start. Concerted efforts in family planning, the retention of girls in school, reduced meat consumption and food waste, and more food production in urban areas, will all help reduce demand. However, we’ll still need much more food as this century rolls on. Modern history has shown that increased food production almost invariably equals less biodiversity, but this needn’t be the case.

One of the major outcomes of the Bitterns in Rice Project to date has been the development of our first edition of Bittern Friendly Rice Growing Tips. They are based on our key findings so far, such as the preference for early, aerially-sown crops, as opposed to combine/drill-sown crops that have dry phases and delayed permanent water. The tips have been widely distributed and a heartening, growing number of rice farmers are incorporating them into their management. Thanks to the generosity and goodwill of one particular grower this season, we’ve begun a pilot study to test the effectiveness of some of the tips across five 3-hectare bays. One is pesticide free; two with only minor early treatment for bloodworm and barnyard grass; and two with management as normal. We’re looking forward to expanding these trials to include the necessary replication of treatments. Plans are also underway to trial dedicated habitat bays incorporated into a rice field that can be managed independently and beyond the rice growing season. The bitterns are our priority, although we’re mindful of the potentially conflicting habitat preferences of different species. For example, sympathetic management of barnyard grass on the banks between bays may provide roaming bittern chicks with cover and improve breeding success, but be bad news for shorebirds including the APS.

IMG_4550     IMG_4496     IMG_4463

Now let’s get back to the burning question: when these approximately 750 bitterns descend on the rice crops for a summer of breeding, where do they come from, and after harvest, where do they go? Thankfully, following the success of the Tracking Bunyip Birds campaign, all will soon be revealed. Surveys during the off-season last year suggested some stay locally and are quite mobile during these colder months, however it appears the majority of the population leave the Riverina. Soon we’ll have a dedicated Bitterns in Rice Project website, and from here people across the world will be able to follow the movements of “Vin”, “Julia”, “Bully”, “Robbie” and the rest of the gang. We’re hoping to be able to begin tracking our first bitterns before this present rice season finishes, pending permits, approvals and transmitter availability, but we may have to wait until next season. In any case, it’s going to be very interesting and downright exciting. Among other things, we’ll learn which wetlands are important for this significant population during the non-breeding season, and whether or not bitterns recorded in areas like south-western Victoria are the same birds that use the rice.

Crucially, the Bitterns in Rice Project has the support of hundreds of rice growers across the Riverina. They feel the habitat values of rice fields are finally being recognised, and many are delighted with the idea of producing food and conserving threatened wildlife at the same time. Again, the marriage of farming and wildlife conservation is as captivating as it is necessary. The false dichotomies of farming and the environment, the economy and nature, us and them, greenies and farmers, urbanites and country folk, humans and biodiversity, all stymie the path to sustainability and deny the existence of a single superorganism: life on Earth. We’re all in this together.

2014-2015 Season Update: First Chicks, Tracking Plans & More

Posted on: January 21st, 2015 by Matt Herring 12 Comments

 

We’re barely half way through and it’s already been a superb summer for the Bitterns in Rice Project. There is much to report. We’re well on our way to achieving great things. The growing interest and support for our work is particularly encouraging. We extend our thanks to all of you, especially the hundreds of rice farmers that are central to the success of the project.

IMG_3282 - Version 2       IMG_3199

Thanks to funding from the Riverina Local Land Services, we’ve established almost all of our 80 core study sites (23-30 hectares each) for this season. We’ve randomly selected rice farms in the Murrumbidgee and Coleambally Irrigation Areas, giving us a powerful base on which to extrapolate our results. Once again, we’re targeting the aerial/spreader/dry-sown rice, which bitterns show a strong preference for, rather than direct-drill/sod/combine-sown rice. We still have many surveys and much number crunching ahead but it’s safe to say there are currently somewhere in the vicinity of 750 Australasian Bitterns in the rice crops of the NSW Riverina. That’s 19-50% of the world total. Amazing. It’s a compelling case to unite agriculture and conservation, and we’re onto it. But like the Amazon and the deep ocean, the secrets of the Bunyip Bird are well kept. Uncovering them will help provide us with the information we need to ensure a healthy marriage between farming and conservation.

IMG_3227       IMG_4282

Two weeks ago we discovered our first nests for the season; one in rice and one in a Cumbungi swamp. Surprisingly, they were at similar stages, suggesting the rice season doesn’t necessarily delay breeding. It was to be a tantalising comparison of diet, chick survival and so on, albeit with a sample size of only one each. Unfortunately though, the Cumbungi nest failed, with predation the likely cause. The rice nest is still going strong and chicks could be hatching as you’re reading this. We’ve begun using sensor cameras with the aim, among other things, to determine the prey fed to chicks. The videos we’ve retrieved so far are astounding, a goldmine of new information and an incredible insight into the secret lives of Bunyip Birds. Below is a single-frame taste (stay tuned).

IMG_4066    IMG_3962     Screen Shot 2015-01-21 at 7.40.14 pm

Last week saw the discovery of our first chicks for the season. In what was easily one of my most memorable days of bird surveying, three nests in three adjacent rice bays were found. Polygyny (a mating system where males have multiple female partners) is more apparent than ever, with this site appearing to support only one booming male and three females. But we have much to learn. There are nine chicks altogether, and as I’m sure many of you will no doubt agree, they are among the cutest, most precious non-human critters on Earth! And you’ve got to love their green skin.

IMG_4642     IMG_4700

There are signs that the key survey window (when we have the best chances of hearing or seeing them) is already closing, with males beginning to quieten and much of the rice above 80 cm in height. If you get the chance to put in some time over the coming weeks, just remember that dawn and dusk will give you the best chance, and there’s always the reward of a nice sunset or sunrise, like this one that featured a thin layer of mist to complement the booming male.

IMG_4242 - Version 2      IMG_4125

Our first four satellite transmitters were ordered last week. We’re still hoping to deploy them before harvest this season, pending various permits and approvals. Special thanks to Inka Veltheim for her expertise in helping decide which units we’ll trial first. It shouldn’t be long before we begin to unravel the mystery of where the approximately 750 bitterns that descended on the rice in late spring and early summer came from.

Our Bitterns in Rice Project website is set for its launch soon. This is where future updates like this will be posted. It will provide an information hub for our work and offer people around the world with the opportunity to follow the movements of bitterns once we begin tracking.

There are a few collective nouns in use like a ‘freeze of bitterns’ or ‘siege of bitterns’. One siege which brought nothing but delight was a siege of four, some pictured below. An excited and persistent male chased an eventually submissive female while two others of unknown sex watched on. It was very interesting.

IMG_3336 - Version 2         IMG_3391 - Version 3

Our paper on the use of rice fields by the globally endangered Australian Painted Snipe was recently published. You can read it here but in a nutshell, and much to our surprise, rice fields can also support hundreds of Australia’s equally most threatened waterbird, further highlighting the potential for wildlife-friendly food production on rice farms.

So far this season we’ve recorded the usual significant numbers of species like Glossy Ibis, Whiskered Tern and Baillon’s Crake (pictured). Around Coleambally it was nice to see the Southern Bell Frogs breeding. We’ve had migratory shorebirds from the northern hemisphere at a few sites, usually Sharp-tailed Sandpipers (pictured) and Latham’s Snipe (pictured), but occasionally something different like a Common Greenshank.

All the best for a big booming year ahead.

THE USE OF RICE FIELDS BY THE ENDANGERED AUSTRALIAN PAINTED SNIPE (ROSTRATULA AUSTRALIS): A RARE OPPORTUNITY TO COMBINE FOOD PRODUCTION AND CONSERVATION?

MATTHEW HERRING1, ANDREW SILCOCKS2

We document widespread use of rice fields by the globally endangered Australian Painted Snipe (Rostratula australis), highlighting the potential for ‘wildlife-friendly’ food production in Australia. A total of 44 Australian Painted Snipe from five of 93 surveyed rice field study sites, and an additional 43 Australian Painted Snipe from three other rice fields, were recorded during the 2012-2013 rice-growing season in the Riverina region of New South Wales. The overall total of 87 birds at these eight widely distributed sites was likely to be indicative of at least several hundred Australian Painted Snipe using the 113 500 ha of rice fields during that period, particularly given the limited survey effort. This is remarkable given the most recent estimate of total population size for the species ranges only from 1 000 to 2 500 birds. The birds were primarily recorded using the shallow edges of rice fields, along banks and channels. Future research should focus on (1) determining if significant numbers of Australian Painted Snipe use rice fields regularly, (2) whether or not rice fields provide suboptimal habitat, (3) the extent to which Australian Painted Snipe breed in these habitats, and (4) optimal rice-growing practices that benefit Australian Painted Snipe without hindering conservation management of the Endangered Australasian Bittern (Botaurus poiciloptilus), which also occurs in these habitats. There are clear environmental costs of extracting water from rivers for irrigation and rice fields are no substitute for natural wetlands. However, given the recognised need for food production and the large area where rice is still grown, targeted management of rice fields to benefit Australian Painted Snipe and other species may be important in complementing traditional conservation measures like protected areas and ecological restoration.

First Ever Bittern Friendly Rice Growing Trials Underway

Posted on: November 16th, 2014 by Matt Herring 4 Comments

 

This is a very exciting. On the back of our successful crowdfunding campaign, it’s a splendid start to the season for the Bitterns in Rice Project. Thanks to the goodwill and generosity of Coleambally rice growers Bernard & Samantha Star, the first ever bittern friendly rice growing trials are underway!

They have donated a total of 15 ha in 5 bays. One will be pesticide free, while two will only receive minor treatment for bloodworm and barnyard grass in the early part of the season. These three aerially sown bays are adjacent to two other bays that will be managed as normal. 

IMG_2213

We’ll be monitoring the frog and waterbird populations, as well as any bittern activity, throughout the season. It will be very interesting to see what differences there are. After harvest, we’ll be able to compare the all important yield data too. This is a taste of things to come. In the future, with the necessary replication of different treatments, we’ll be able to fully test the effectiveness of our bittern friendly rice growing tips.

Special thanks are due to SunRice Grower Services for donating the seed and to Coleambally Irrigation for their general assistance in making the trial happen.

It’s been great to see some more early bitterns this week too. The rice is looking better by the day, especially at these more advanced crops. Perhaps these early birds are the ones that stay locally over winter, rather than those that move away after harvest. The first booms are imminent. Thanks to Peter Sheppard for this great shot from earlier this week.
