Virtual fence saving hundreds of kangaroos

Wildlife rescuers say virtual fence saving hundreds of kangaroos on Victoria's Surf Coast.
Removing wildlife carcasses from the road is a usual morning for Jason Cichocki but he says a new technology has more than halved the number of animals colliding with vehicles.
there are also other ways to reduce collisions, some even similar with less tech, e.g.
reflectors, which reflect headlights to create an optical illusion of a fence and alert deer to oncoming vehicles, have been reported to reduce deer/vehicle collisions by 60 to 100% [humanesociety]posted by HearHere at 7:52 AM on November 16 [2 favorites]
What's next?
Experts say more research is needed to evaluate the effectiveness of virtual fences and the best solution is for road users to slow down.
"Every heartwarming human interest story inamerica australia is like "he raised $20,000 to keep 200 orphans kangaroos from being crushed in the orphan kangaroo-crushing-machine" and then never asks why an orphan kangaroo-crushing machine exists or why you'd need to pay to prevent it from being used."
but he says a new technology has more than halved the number of animals colliding with vehicles.
If we want to reduce the number to zero, I know of a few simple and cheap technologies for slowing down cars, with varying degrees of permanence.

Great idea that appears to work...
Aaargh! what's this BS?
"We need both more data on these virtual fences to determine whether or not the claims that are being made about their effectiveness are correct"
I've worked with nature since 1990 and continually hear this, and when I raise concerns about lack of action the most common reply is 'we're building a database', and yet every wildlife person within 50km knows whatever the thing is it's a serious growing problem. And multiple times I've seen that process become so serious it is "too costly to solve". The anmoying thing about the scientific model is that merely having a science degree and practicing what one has learned gives no legitimacy to mere field officers and contractors.

The same article goes on to say
A three-year trial on Phillip Island between 2019 and 2022 compared roadkill numbers in fenced sections with unfenced sections and found there was no significant effect of the virtual fence on roadkill rates.
Ultrasonic roo shoo things that you attach to a vehicle have been around for decades and are the type of snake oil that people buying and selling them seem to really believe in but with no great evidence behind them actually working very well. This seems a lot like that.

Yes, well, until the day your glorious revolution arrives, I’m glad there are also people working on more immediate and practical solutions.
