Blackwater pools - Scott River - Blackwood River
The blackwater pools near East Augusta have large numbers of Galaxiella nigrostriata (might write more about them in a future thread), but also, literally thousands of tadpoles, dragonfly nymphs and small koonacs and gilgies (seeing them so much, instead of actual fish can get irritating ). Lepidogalaxias salamandroides are recorded to occur there, but I didn't see any. I might have more luck with them in summer, when the pools are smaller.
Speaking of the pools, I do not believe they dry out completely in summer, otherwise no aquatic plants would grow
Also saw a turtle, which was cool. No introduced fish or invert species, the pools are completely disconnected from any tributary that might permit introduced species to enter the pools.
I was surprised by all the native plants, there were a few species of fully aquatic macrophytes (I know one of them was Triglochin procerum but I'm unsure of the others), even lilies. I doubt they're feral species.
Gingin Brook - Moore River
I mentioned this one in a separate thread, but I completely forgot to write about it here.
The upper Gingin Brook is dominated heavily by introduced plant species (not surprising though, seeing as how there is farmland on either side of the brook), but in contrast, there are no introduced fish and invert species, only natives, probably because of the presumably completely zero salinity. There is a single aquatic macrophyte, not sure on the species but it's similar to vallis.
The water flow is moderate.
There are Nannoperca vittata, Galaxias occidentalis (which are in lower numbers), Palaemonetes australis, Pseudogobius olorum, Afurcagobius suppositus (which I've seen attain huge sizes; around ten centimetres long), Cherax quinquecarinatus (C. tenuimanus also occur there, though I haven't seen any; C. preisii appear to be absent), Galaxiella munda and Bostockia porosa.
