50 shades of green in an electrifying Easter

There’s nothing black and white about being a farmer like me; there are about 50 shades of green. For this greenie farmer has a big problem that is not widely appreciated outside farming circles and, in fact, denied altogether by greenies of a different shade. It’s a kangaroo problem.

The side of the farm that adjoins state forest hosts about 300 kangaroos and wallabies every day and they’re quite literally eating us out of house and home. Last year, we and the cows harvested around 10 tonnes of dry matter per hectare (DM/ha) on the non-forest side compared to just 5 tonnes DM/ha on the half of the farm that sits next to the forest. The bottom line: it’s not even paying its share of the mortgage.

How could a few hundred macropods make such a dent in the farm when researchers say they don’t compete with cattle? First of all, the research was done in semi-arid land, which is not comparable to dairy farm pasture.

Rye grass, the dominant dairy farm pasture species, is sweet, much lower in fibre and easy to snip off at ground level if you have upper and lower teeth. Cows don’t – they only have one set of teeth and wrap their tongues around the grass to eat it – which limits how short they can eat the grass.

Kangaroos and wallabies have wonderful teeth for eating really tough native grass that also make it possible to raze less fibrous grass to ground level, which is exactly what happens on our farm.

You could host a lawn bowls championship on our pastures closest to the bush, year round. Rye grass just doesn’t cope with that kind of pressure. It needs rest time between grazings so it can replenish its energy stores enough to push out new leaves and grow healthy roots.

Just a couple of years ago, we discovered that not even a vigorous fast-growing crop like oats can outrun our kangaroo population.

So, what are our options? We got a licence to cull 40 kangaroos a year but never fired a shot. It would be like trying to push back the tide and I have no appetite for creeping around in the chilly dawn air with a gun every week. I find it gut-wrenching enough to euthanase a suffering creature, let alone stalking Skippy.

Next, I tried the great Maremma experiment. Charlie and Lola have turned out to be fantastic livestock guardians but they’re almost too good. When a threat approaches their calves, Lola stays with the poddies while Charlie ventures out to see whatever it is off the premises. They are effective for about a 50 metre radius of the calves but not hundreds of acres.

I even investigated spraying dingo urine around the boundary and all manner of sonic deterrents but found them either ineffective or impractical.

It’s come down to a cracking great electric fence. I’ve taken out a new mortgage to install it with real regret because we’ve had to remove trees to put it in and I know we’re committing ourselves to a lifetime of intensive maintenance.

The fence is only halfway around the boundary so far but I’ve already got a taste of what it takes to make it work. It will take more than one nasty shock to convince our visitors to dine elsewhere and kangaroos prefer to go under rather than over fences, so I have to keep the fence fired up all the way down to the wire that almost scrapes the ground. Longish green grass is enough to sap power from the system and have the roos squeezing under again.

I’ve spent a lot of time with my fence fault finder this Easter and I have a suspicion the fun is just beginning.

So, being an ethical farmer is not as clear-cut as you might think. If I carried on as we have been, we would be providing a great breeding ground for hundreds more roos than the bush can sustain and saved the felling of what I’m guessing was a thousand trees.

Building the fence means a more resilient farm that no longer relies on fodder bought in from across the state. It also means that I might finally be able to extend our program of planting 1000 trees a year to add to our 27 hectares of native forest on that side of the farm without the seedlings being wiped out.

Most importantly, if I am being honest, it secures the farm for our children. What would you do?

  1. Remind me not to pull over and take a water break on your fence any more then…would light up the skyyyyyyyyyyyyyyyyyyyyyy and wake up the neighburhurhurhurhurrrrrs.


    • No market for organically grown grass (and oat) fed macropod Marian? (ie bring in a commercial shooter?)

      Always amazes me what farmers have to do just to stay afloat. The Brumpton’s in Qld had to build a 50km, 6 foot high fence around their property to control the wild dogs (and roos).

  2. Your roos sound like our deer here. Beautiful creatures, but can really destroy crops. We had to put up 8 ft deer fencing around the pinot noir, and use Deer-Off repellent on the table grapes. They will nip new shoots back to the trunk of the vine. Later in the season we stop the deer-off, as the canes are too woody to be of much interest to them at that stage, and anything the do eat is less canopy management. People with dogs have less of a problem. Elk can make a mess of a vineyard as well.

    Bears and beehives – the bee club used to send photos around of what a beeyard looks like after bear attack. They are 4-legged tornadoes. One club member who used to pollinate crops commercially used to sleep amid his hives with a loaded 45. Some have tried electric fence, using a section of hog fencing as a foot plate the bear steps on first.

    All in all, we don’t have too many problems here as we don’t have livestock. Our main worry now is water. The winter has been too warm and dry.

  3. Just off this week to teach some units of Cert IV Conservation & Land Management. OK to use your article (50 shades of green…) as a management issue example for the class ? If so, I will let yo know if they come up with any revolutionary but practical ideas.
