To see if there
has been a more general crash of EPP populations from 2017 to 2018
into the depths of this drought I have taken a snapshot on 20 August
2019 of the EPP sightings recorded in BioNet for the years 2017-2019
for the LGAs and NPs I am licenced to operate in:
||Northen Beaches LGA
||Lane Cove NP
|2019 so far
As you can
see, recorded sightings have dropped dramatically echoing what appears
to be an EPP population crash. The EPP population may revive somewhat
if this prolonged period of insufficient rainfall breaks by autumn
next year, otherwise we may be consider placing EPPs on the endangered
list for NSW.
Note also the
1. The inceased
sightings in KCNP in 2019 largely reflect my increased activity
in that national park.For Hornsby LGA, I will extend my camera monitoring
to the more northern areas following my negative survey in Lane
Cove National Park to improve the sampling there.
2. There does
appear to be the danger of a local extinction event in Garigal National
Park (joining Lane Cove National Park in this status).
