eDNA results for november 2023
In November 2023, 51 sites were sample across the Wollombi catchment between 8th-13th November, and with over half of those monitored by local volunteers and landholders. A wonderful effort by all the community!
Results from the eDNA sampling were:
6 locations were positive for playtpus DNA (Orange Tick)
8 locations were equviocal for platyus DNA (Orange with white dot). This means DNA was found but not enough to be confident of presence..
1 location had Rakali DNA as positive - (Purple tick)
Green marker pins mark a site sampled but with no result for this sampling round.
eDNA results for april 2024
In April 2024, 54 sites were sample across the Wollombi catchment between 3rd-11th April. Another phenomenal effort by everyone involved with more than half the sites monitored by volunteers! Thank you everyone!
For Round 2, we got double the positive results and equivocal results than we had from November 2023 sampling (Round 1) for platypus, and more positive locations for Rakali. The catchment was fairly low in flow prior to getting 80-100mls of rain over the weekend of 5th-7th April. Samples were collected on both sides of this rain event.
See the map below for the results from the eDNA sampling were:
12 locations were positive for platypus DNA (Orange Tick)
17 locations were equivocal for platypus DNA (Orange with white dot). This means DNA was found but not enough to be confident of presence. (5 of these matched with positive results)
5 location had Rakali DNA as positive - (Purple tick)
2 locations were equivocal for Rakali (Purple with white dot)
Green marker pins mark a site sampled but with no result for this sampling round.
