Numbat survey at Boyagin Nature Reserve with Project Numbat

My buddy Jimmy had been talking for a while about the annual numbat surveys he helped with, for Project Numbat and Parks & Wildlife Service (part of DBCA).  I had been interested for a while but with little kids it’s a huge ask to leave my wife with the kids all weekend, this year the ever gracious Mel was happy for me to join the team.

Jimmy had been instrumental in my first sighting of numbat and it wasn’t an ordinary quick glimpse but an extended viewing of a pair just before mating.  It was my 4th time trying to see them which gives an idea of the rarity and how difficult they can be to find.

Project Numbat survey both Boyagin Nature Reserve and Dryandra Woodland once a year.  Project Numbat are a not for profit group with a focus on community awareness and conservation of the numbat.  The type of survey we would be conducting was a digging survey as just visual surveys can miss animals and they leave distinctive markings when they forage for termites which persist.

Jimmy and I headed down once I had the kids mostly ready for bed.  We would be staying at the lovely Lions Dryandra Woodland Village and travelling to Boyagin daily which is about 30 minutes away.  We got there after dark and couldn’t help but go for a spotlight – we were hopeful for Pygmy possum that Jimmy had seen in some flowering bushes a year earlier and also after a couple of trips Jimmy had made earlier in the week.  Unfortunately it wasn’t the evening for Pygmy’s but we found a couple of lovely Woylie (Bettongia penicillata) in the area.

We headed back to Lions Village to get some sleep as we had a full day of surveying the next day.

We got up and had breakfast with the other volunteers.  Also joining us was Dr Tony Friend from Parks & Wildlife – Mr Numbat himself!  We had six of us in total and split into 2 parties and headed out to Boyagin to make a start for the day.  My group comprised of Tamara (President of Project Numbat) and Jimmy. 

First task of the day was to practice in identifying numbat diggings – they are quite small, not too deep, discrete diggings without a mound of dirt.  These are left after exposing termites in their galleries just beneath the surface and licking them with their long tongues – they are also often grouped in a run as the numbat follows the food in the galleries – see below photo.  Other diggings that need to be ruled out are the following:

  • Woylie (deeper v shaped hunting for underground truffles) – often earth left mounded
  • Quenda (funnel shaped)
  • Rabbits (often with scat present)
  • Echidna (messy often covering a large area)

The survey consisted of driving to pre-defined locations and then the group surveying an area of 100m radius for a period of 10 mins.  If diggings were found others confirmed or disagreed.  Once located, a quick search was also made for numbat scat – hard, quite heavy black with shiny bits of termite exoskeleton inside.   The locations are spread out throughout the blocks of Boyagin and allow year-to-year comparisons of numbats.  Records were kept on Project Numbat Toughbooks in a GIS application.

It was rewarding to find evidence of numbat foraging and also noting how you can tell if a site habitat was more ‘numbatty’ depending on the vegetation and fallen trees present.

We saw plenty of Gould’s sand goannas (Varanus gouldii) crossing the tracks and also got a glimpse of a black-headed monitor (Varanus tristis) but it didn’t stay for photos!

We came together for morning tea & lunch and it was nice to hear how the other group were getting on.  They, like us, had some sites with repeat records of numbats from previous years, some had new records where they hadn’t been found before, and some sites that previously had diggings but didn’t this time.  Such is the way of scientific survey.

We finished off the day’s surveys feeling like we had made great progress – setting ourselves up well for the next day. Tamara cooked an amazing green chicken curry with rice which went down a treat after all the work of the day. Just before dinner one of the team mentioned they had seen a Gould’s goanna just outside our cottage.

That night the rest of the team were going to settle in for a relaxing night and enjoy some well earned beverages, but Jimmy & I we wanted to see more wildlife. We headed out as it got dark going back again to our Pygmy possum spot – with still no luck! We had a very nice viewing of a Tawny frogmouth that just stayed put. We also saw the usual collection of Woylies, Brushtail possums and Western grey kangaroos. We also spotted a nice Western spotted frog. Highlights were spotting a couple of Chuditch – in a couple of hotspots that seem to have animals every visit – no photos as the animals were skittish that night.

We headed to the sandalwood plantation previously mentioned to see if we might see Red-tailed phascogale, and it’s always good for Woylie. Many woylie were seen and Jimmy saw an Echidna that I didn’t see. Hitting the carpark I found this beautifully marked Wheatbelt stone gecko (Diplodactylus granariensis) – a new species for me. We headed back knowing we had another full on day tomorrow.

The second day Jimmy & I were with Tony Friend (numbat guru). We changed plan this day deciding not to meet for morning tea but would meet for lunch at one of the dams. Discussions with Tony were great and I learnt lots about many topics!

At one point we were just heading for a corner where two tracks met and Tony calls “Numbat! and I would like to catch it”! It bolted, as did Jimmy, who hadn’t seen it from the back seat but was doing his best to find it… Unfortunately it was too fast and this was our only sighting of the weekend. Tony will sometimes attach radio collars or make an assessment of the general condition of the animal, so not just catching for fun.

I learnt heaps from chats with Tony and totally enjoyed the day. We caught up for lunch and learnt that the other team had seen a carpet python which Jimmy had been dying to see – but no luck for him this weekend! We headed out after lunch completing the last few sites before finishing for the day around 2pm. We took some team photos before we headed back to Perth. A great weekend all round – I learnt heaps, met amazing new people and had lots of time in the bush!
