It is standard practice for regular collectors to collect a number of vouchers so that duplicate specimens can be lodged with relevant state herbaria.

RECORDING SEED COLLECTIONS Records serve the function of being able to tie the collection to a field number, herbarium voucher, and a range of information on that collection.

Delaying seed germination until 19 Australian Seeds environmental conditions are favourable for establishment ensures seedling survival and continued reproduction of the species in the environment. Seeds must simultaneously sense a number of environmental conditions and time germination and emergence to particular times and habitat locations for successful establishment and survival. Temperature is one of the major drivers of dormancy loss and seed germination. For many Australian species in temperate and Mediterranean climates germination tends to be best at temperatures associated with the winter rainfall period (approximately 15–20°C) and seeds remain dormant at lower or higher temperatures.

Having the best quality gear will mean that unexpected failures in the field are kept to a minimum. Different tools may be needed depending upon the level of sophistication and the quantity of seeds required. The checklist above is intended as a general guide to those items that are useful and those that are essential for the collector. TIMING OF THE COLLECTION TRIP Seeds should be collected when mature and at the point of natural dehiscence. At this point, the fruits and seeds are usually becoming dark in colour, material is dry and becoming woody and in many cases seeds are falling from the plant or becoming airborne.
