Record snowfall in the Snowies and these fellas are loving it! Benefits of data collection in Kosciuszko
I have started a Masters level research project into characterizing scavenger guilds in Australia’s rare Alpine environment. This truly unique and valuable ecosystem is home to some incredibly rare flora and fauna which makes this all the more exciting.
It was a lovely day at Wolgan Valley in the Blue Mountains seeing some site setups for my upcoming research in Kosciusko NP. Got lucky with this display from an Eastern Bearded Dragon
I recently went on a trip with the Desert Ecology Research Group to their Ethabuka site to assist in some field studies. I got to say this was an amazing experience driving out into the loneliness of the Outback.
It’s really been a great exhibition of different land and livestock management. People out here own HUGE amounts of land measured in the hundreds of thousands of hectares and outlined by their fencing. Each barrier creates an ecological experiment and window into the risks of poor management choices. It becomes quite obvious who is treating their land well with an eye towards sustainable agriculture and who would prefer to liquidate any sort of productivity as they graze their land into oblivion. Even out in a place where as little as 30ml of rain and an average low temperature of 30C the landscape was never meant to be completely barren.
In places where the cattle are restricted or not at all there are beautiful slow growing gidgee tree and spinifex which play host to countless diversity of reptiles, amphibians, mammals, and birds. It’s hard to imagine that such an intensely harsh environment is jam-packed with life.
Life in the outback is just different than what we know as a western culture. We have been conditioned to be able to do anything when and where we want without consequences but life here operates as a powerful reactive force; the boom and bust cycle. Life out here knows that it must wait until times are good to flourish. Desert amphibians are just one superb example of this hibernating beneath the sand dunes for years until the slightest bit of rain awakens them. On any other day of the year you would never expect the sun-scorched dunes to be covered in so much semi-aquatic life.
But unfortunately the outback is under attack by misguided agricultural practices. Huge areas of land have all but been annihilated due to intense overgrazing, their surface more resembling the barren deserts of Mars than our own world. Farmers leave their cattle on these decimated landscapes for years propped up by artificial watering holes with the business model of: “the rain will save me next year”. But in arid-Australia that’s not how life works and agricultural land is steadily losing all it’s productivity
There is hope though and it comes from bringing an ecological prospective into the agricultural industry. Like a thought that’s been pushed to the back of your mind everyone knows it but refuses to acknowledge it; who knew that treating your land well is better for your future and your profits. Slowly but surely some livestock owners are adopting ecologically minded practices and reaping the benefits of them.
Angus Emmott is among them as a beef farmer who has decided to not shoot and poison bait Dingos and as a result receives less grazing competition from kangaroos. This benefit is very apparent as evidenced by his greater vegetative productivity. This free ecosystem service this top carnivore provides creates a landscape of fear in the kangaroos and some cattle moving them more in the pastures and relieving grazing pressure on plants. This agrigated precious time regained by the foliage allows more nutrients to stay in the topsoil which in turn allows for more plants. More Dingos leads to more plants leads to more food for animals.
Greater productivity in the outback can also be seen in lands that have been allowed to rest between flooding events. Absent of people, outback fauna are largely scarce until large booms of green-up brought on by chance rains. Animals out here have learned to utilize the good times and become scarce in the bad. So why do livestock owners leave their animals out in the harsh landscape in times of drought? Most operations appear to make a profit when it rains. Wouldn’t they favor letting the land rest and allow for greater vegetative build-up so they can have more profits more often?
So maybe the future of an agricultural outback needs the support of natural patterns to thrive. Understanding these boom and bust cycles is essential to insure a healthy Outback for nature and livestock. The alternative of relentless grazing pressure is far worse than letting it recover. No one wants to see these farmers graze themselves and their communities to oblivion which is what is currently happening.
This isn’t anyone’s particular fault though and a lot of why things are hard to change are because state and federal rules regarding agriculture have not been given any incentive to change. From a country commerce level the difference of managing your land responsibly vs utter destruction is purely on the output of livestock. There is no widely accepted way to quantify the resilience and the sustainably these animals come from and what matters more to the future of the industry. This is where governmental power can really shine and where foresight can make so many lives that much better. Unfortunately for Australia no political official in recent history on the state or federal level has stepped up to challenge this blight of poor agricultural policy and has instead opted for the cowardice of inaction. As a nation the position is open for someone to be brave and act accordingly with the science and the small farm communities to incentivize sustainable practices. We know they work so why not make them more effective.
There are ways to responsibly use some Outback that allows for some grazing without the annihilation of icon desert species. This might take:
- Allow for the recovery of Dingos and wild dogs (ecologically they do the same thing) and prevent further baiting programs. Carnivores manage grazers and land better than people can.
- Reduce some grazing pressure in times of drought. Vegetation begets vegetation.
- Government incentives need to change from anti-carnivore productivity liquidation to policies that reflect how ecology works. Compensate farmers on their losses not encourage them to burn up the tool which they use to live.
Right now some of these farms run a deficit each year there is no rain but it’s too expensive to change their current operation. Farmers may be locked into a certain way of doing things on land that continually declines until it becomes entirely unusable. No one wants to see these economic hardships so that’s why it is imperative we change and reinforce sustainable practices so we can thrive into the future.
Nature and people can live together and we want to work with each other do do so. It just takes the trust that changing to an eco-friendly is a better option.
A while back I created a map to help out the WIRES call center operators more quickly identify associated veterinary practices around incoming wildlife rescue calls. Although they may have moved on to different technology since then, here is a public version of the map I’ve created. Who knows this may still help any interested member of the public identify nearby triage centers if they’ve found any injured Australian wildlife in New South Wales they’d like to help out.
The map includes the WIRES regions as well as other wildlife rescue organizations that operate in tandem. Vet practices have been organized into categories of hours of operation as well as specialty. The full-size version includes the all important search function which allows the user to pinpoint a location using Google Maps and helps identify the closest center around with the corresponding layers.

I’ve compiled our data we collected at One Tree Island into this video and sped it up. Its kind of mesmerising watching the schools of fish dart in, out, and between the corals.
Science question: Do the Whitetail dascyllus (humbug damselfish) prefer acropra sp. or isopora sp. and can it be quantified?
Went to One Tree Island Reef, a small coral cay in the southern portion of the Great Barrier Reef to study habitat preferences of fish on corals. It’s a beautiful ecosystem that I believe everyone should get to see in their lifetime. Definitely a place worth protecting and the reason why people should care about anthropogenic climate change.
This sly laughing kookaburra was putting on a show and didn’t seem like he minded the media attention. Found him at the University of Sydney’s Crommlin Research facility in Pearl Beach.
Quite the photographic birdy.
Found this fella out at Royal National Park, NSW. Was kind enough to post for a portrait.
