This data collection exercise contributes to the National Koala Monitoring Program (NKMP), a nationwide initiative that links old school ecological survey techniques with cutting-edge technology like thermal drones and the Koala Counter app. Following CSIRO guidelines, we set out to see how koalas are responding on a project site after some major works – think weed removal and native plant regeneration to reconnect patchy forests on farmed land.

As it turns out, playing Where’s Wally with koalas while lizards, cats, and possums skitter across your path is so much harder in the dark!

The double observer transect method: science meets strategy

The double observer transect method is the NKMP’s not so secret weapon for counting koalas, and it’s pretty clever. Here’s how it works:

• Two observers start at opposite ends of a set path (the transect line).
• They walk toward each other, scanning the trees like hawks.
• Each records their koala sightings independently in the Koala Counter app.
• At the end, they compare notes and resolve any discrepancies.

This method really works because it accounts for the fact that koalas are masters of hide-and-seek. By using two observers, the NKMP method ensures the data is accurate and verified, making it possible to compare today’s findings with data from a decade ago.

Why this matters: the bigger picture

Consistency is key in conservation. By using the same methods across different sites and over time, researchers can track long-term trends in koala populations. For Indigo and Tom, this means monitoring how koalas are responding to our habitat restoration efforts. Are they moving more freely? Are they using the newly planted areas? How long does it take them to use revegetated areas?

The data they collect helps answer these questions and shapes future conservation strategies.

The NKMP: Saving koalas, one data point at a time
	The goal of the NKMP is to locate koalas across Australia and figure out accurate population sizes. We know koalas are endangered, but having a clear picture of where they are persisting helps everyone target limited resources more effectively in our collective conservation efforts. Tom and Indi introduced me to the citizen science-friendly app - Koala Spotter that lets anyone log koala sightings and habitat conditions, so I downloaded it onto my phone for my future hikes.

How you can play Where's Wally with koalas in your local area

If you’re as pumped about koala conservation as I am, here’s how you can help:

1. Download the Koala Spotter app and log any koalas you spot.
2. Join a community survey—it’s a great way to meet like-minded people and contribute to science.
3. Support local conservation and Landcare groups working to restore koala habitats.
   Every bit of data and every action counts!

Remember to look up
With programs like the NKMP and passionate project managers like Indigo and Tom, there’s a real chance to protect koalas and their habitats for generations to come. So, next time you’re out in nature, look up and keep your eyes peeled for koalas. You might just spot one—and if you do, don’t forget to log it in the Koala Spotter app!

Karis’ takeaway: monitoring is key for continued success

Being out in nature, learning about koalas, and seeing firsthand the impact of conservation work was incredibly rewarding. Our work alongside many amazing landholders is not just about planting trees or pulling weeds—it’s about understanding the delicate balance of ecosystems and using local knowledge to make a real difference.

Indigo and Tom’s passion for their work was contagious, and they reminded me that conservation isn’t just for scientists—it’s for everyone. Whether you’re logging a koala sighting on the Koala Spotter app, joining a community survey, or supporting local habitat restoration by joining a Landcare group, everyone’s contributions to building a bigger picture help us manage our landscapes.
