Some plants, such as Acacia or Kennedia, dehisce over a number of weeks, meaning collecting times can be staggered to suit a programme. Many species will not produce healthy seeds if the rainfall throughout the growing season has been inadequate. Woody shrubs such as Acacia may abort their seeds if conditions are bad. Thus, although general collecting times can be set for a species, given the vagaries and seasonal variation throughout Australia these must be fairly flexible. Maintaining long-term observations of plant populations and variations in seed set from year to year will improve decision-making on when seeds are best collected.

The best of these are light canvas sheets used by painters. These are essential for collecting seeds from many acacias. All collections should be labelled with (at the very Acacia seeds collected on drop cloths in calico bags. least) a unique field number and preferably a field number, date and the name of the species. Material that is damp should be packed more loosely and placed in a drying environment as soon as possible. Wear appropriate protective clothing and eye protection. Some groups, such as grevilleas, can produce allergic reactions.

Set goals about how much material you need so as not to waste time collecting too much or too little. • Make clear judgements about the material. If it is not mature, then leave it for a later time. PLANNING A COLLECTION TRIP Thorough research and planning before leaving on a trip is crucial. Field-based collecting can be an expensive undertaking and it is important to get the maximum benefit from fieldwork. A well-organised programme with realistic targets is the best way of using time effectively.
