I received a letter from 'Trees For Life' - an organization of which I'm a member:

"Dear Seed Collector,

Enclosed is your seed collection permit for the coming season.
...
I like to ensure that members who attend a seed collection workshop have a permit for more than a year.
..."
Okay, I attended a workshop in June. It was winter and freezing cold. The room where the introduction took place was not heated and I was not able to follow the lecturer. I only concentrated on my feet. How blue they may be and how they are slowly turning black. And when I will take off my shoes how the necrotic feet will fell off. It was a torture. So I left the (very good!) presentation an hour later - 5 hours earlier than expected. Now I have not really an idea how to collect seeds.
[Excerpt of the list of seeds needed for the seedbank:
Acacia argyrophylla, Acacia ligulata, Acacia nyssophylla, Acacia oswaldii, Acacia pygnantha, Acacia retinoides .... Senna artemisioides, Vittadinia blackii, cuneata or gracilis]
