Hi good people.
Those South Australian Birds in Backyarders who are interested in attracting native birds & other wildlife to their gardens & properties might be interested in this website: http://saseedbank.com.au/.
I've been browsing through some of it today & it's one of if not the best website of its type I've ever encountered. As well as telling which species in the database grow where in SA it has great photos of seeds, fruits, plants etc to aid in identification. There's a plethora of information about plants including how to treat seed to aid germination.
The website is still a work in progress so it's not comprehensive but the folk in charge seem to be moving towards making it so.
