Plant Adaptations - Your Input Needed

8 November 2007 7:43 AM

I've received the following request from Florabank.

This is a call for information to all those tuned into one of the more pithy areas of knowledge about the plant world at the moment and that is provenance. As you know, documenting our current understanding of how plants adapt and vary will help us to make the right decisions in how a species is managed. Florabank is compiling what we know and what we don't know about plant provenance for those key species commonly used in revegetation. Florabank will share this information through their website.

Plants can have adaptive variation in survival (frost, drought, fire, wind, waterlogging), growth rate, habit, salt tolerance etc. These adaptations are passed on in subsequent generations. It is this diversity in the plant world that Florabank is looking to protect. It will have important implications in the future, particularly for revegetation projects.

Have you observed significant adaptations in a species in your region? How are these differences expressed in the plant's morphology? Have you noted why there are clear differences, for example is the plant growing in a different soil/geology, climate, altitude. This may be a new plant provenance. If you are happy to share your information with everyone else, please email us at florabank@greeningaustralia.org.au

This is a list of species we are looking for feedback on so far:

Austrodanthonia caespitosa
Austrodanthonia setacea
Austrostipa mollis
Babingtonia behrii
Baumea articulata
Chrysocephalum apiculatum
Dichondra repens
Eremophila debilis (syn. Myoporum debile)
Eremophila longifolia
Lepidosperma longitudinale
Leptospermum obovatum
Maireana brevifolia
Maireana microphylla
Mallotus philippensis
Olearia viscosa
Rhagodia spinescens
Schoenoplectus validus
Xanthorrhoea quadrangulata
Xerochrysum viscosum (syn. Bracteantha viscosa)

Xerochrysum viscosum

Your contribution will make a big difference to the conservation and management of our Australian flora and help those who love Australian plants as much as you do!
