Factors to Consider when Collecting Seed
The site in which the seedling will be planted
This will allow you to collect seed from plants which have grown in similar soil type and
climatic condition to where you intend planting it.
Local indigenous species generally perform the best as they are naturally
adapted to their new home.
Seeds from the same species but different areas can have very different levels
of tolerance to such things as frost and drought tolerance. It is important
to try and match these characteristics.
The characteristics you are looking for in the adult plant
The final form of a tree is largely affected by its parent.
The form of the tree from which you collect can, therefore, have a bearing
on the final look of the propagated plant.
It is therefore, important to select the seed from a tree whose form is suitable
to your purpose eg timber, flower, foliage etc.
Genetic diversitySingle trees will often self pollinate, generally resulting in lower yields and the possible
dominance of a single negative influence.
To reduce the possibility of these problems it is often better to collect
from trees which have neighbours of the same species and a reduced chance
of self pollination.
If possible collect from 5 or more seed plants of the same species, spread
at least 100m apart to further maximise the genetic diversity
TimingMany species will shed their seed very quickly once it has matured so it is crucial to
know when and where the seed will be ripening.
Heavy flowering will often be a prediction of high seed yield so it is good
to be aware of the flowering times approaching seeding and identify the best
ModerationCollect only as much seed as you need.
Only 10% of the seed should ever be taken from one plant to leave a sufficient
supply for the tree and other living creatures dependent on it as food source.
So don't get too greedy!!!
HabitatTake precaution when using vehicles and on foot to minimise any damage to understorey plants
and be sure to leave all nesting sites, tree hollows and other fauna habitats undisturbed.
Disperse discarded seedHarvested twigs
and discarded seed capsules can be distributed along the roadsides or in
areas where there is a possibility of some germination.
Seeking permissionPermission must
be sought to collect native seed from:
- Local Government
Municipalities- in writing for the collection on some roadsides
and all public reserves
- National Parks and Wildlife Services- for collection in all national parks, historic
sites, state recreation areas, nature reserves,
state game reserves and aboriginal areas and for collection of protected species as defined in
schedule 13 of the National Parks and Wildlife Act 1974
- State Forests require a licence for seed collection
- Relevant authorities responsible for managing other lands
