IMAGES of environmental damage by feral goats and deer feature among the winning entries in the annual Centre for Invasive Species Solutions photo competition.
The winning images of the annual photo competition have captured the dark side of pest animals and weeds; showcasing infestation, damage and death, and emphasising the need for coordinated management to create positive outcomes.
This year the winning images, encompassing all corners of Australia, highlight the dramatic damage caused by pest animals and weeds. However, each image also tells a unique story of how communities and landholders are fighting back to tackle these big problems.
The image of goats dancing on a Malleefowl nest was taken by Fiona Gray who monitors the threatened bird species as part of her role as Regional Landcare Facilitator for the South Australian Department of Environment, Water and Natural Resources.
“We were monitoring the nests as part of a collaborative feral predator control campaign in the South Australian Mallee, which involves landholders, the local Green Army and Landcare coordinators.
“We were trialling the use of Canid Pest Ejectors in the region, and had remote cameras set up to see if feral predators, such as foxes or feral cats, would activate the ejectors,” she said.
“To my shock, as I was going through the images, instead I see feral goats jumping ‘and dancing’ around right on top of the nest, where the Malleefowl eggs were laid.
“I showed the image to one of the local landholders who took it upon himself to trap and remove the feral goats using our mobile goat yards – I am pleased to say the Malleefowl did return to the nest,” Ms Gray said.
Red deer damage photo was a winner
An image of a red deer destroying a paperbark tree with its antlers was entered by James Gummer who captured the image with his trail camera, set up in the Murray Shire of Western Australia.
“While deer numbers may be low and isolated in the region, they are certainly having a negative impact on the local wetlands they inhabit.
“We see evidence of deer trampling protected plants, muddying areas used by native frogs as homes and ring barking trees by rubbing their antlers against them – which as my image showcases, causes severe defoliation and even death of the trees.
“Deer can be a major problem in these protected areas, so I am glad to see that deer are now being managed accordingly,” Mr Gummer said.
This year we also opened our competition to weed photos, and were looking for an image which showcased severe infestation.
Creepy Cats Claw Creeper photo
The winning image of Cats Claw Creeper taking over the banks of the Timbarra River, near Drake NSW, was taken by Mandy Craig.
“Cats Claw Creeper is extremely deceptive – it looks harmless, pretty even, but they can form a dense mat and smother large native trees until they die.
“The impact is two-fold – as the tree dies and collapses along the river, it can also cause severe erosion and instability around the river banks, impacting the whole river ecosystem,” she said.
“Landcare has been undertaking control of this weed in this area for a number of years and has now established a containment line.
“In the past nine years, when funding is available, we have used contractors who manually remove the weeds. However, when it gets to this stage, like in the photo – it is extremely hard to eradicate.”
Ms Craig said the local Landcare group is now considering biological controls as a course of action, and we are seeking further expert advice on this.
Ms Craig reiterated that while some weeds can look pretty, when they get to infestation level, they are extremely damaging to our native environment.
“The Cats Claw Creeper flourishes as a yellow flower which many people think are native, however I do recommend that anyone who thinks that they might see Cats Claw Creeper in their area to alert authorities so that appropriate action can be action before it is too late”.
Centre for Invasive Species Solutions chief executive officer Andreas Glanzig emphasised how one image can paint a very detailed picture.
“These winning images show the devastating consequences of invasive species, and I am extremely pleased to hear that in all cases, local coordinated action is being undertaken to tackle these problems, and new and innovative tools are being used as part of the management solutions,” he said.
