There is so much Water Primrose this last year at Jarramlee Pond it appears to have brought in more wildlife. The landcare group's annual bird survey is showing up a couple of extra water bird species but more importantly they are sticking around. Same occurrence but to a lesser extent at neighboring Fassifern Pond. Thanks for posting.
I would be a bit cautious about attributing numbers of waterbirds to occurrence of Water Primrose. My observations after travelling around Southern Tablelands this autumn looking at plants in dams and wetlands are that most waterbodies have more waterbirds present than expected: i suspect waterbirds are responding at to physical or weather conditions way beyond ACT.
