Seed collection techniques
If the assessment confirms that a good quality seed collection, of sufficient quantity, can be made from a population, the collector can go ahead and gather seeds.

Once the collecting team confirms that seed from the target plant species is suitable for harvesting, they collect seed from randomly selected plants at that location. For long-term conservation, seed will be collected from at least 50 individual plants. Up to 20,000 seeds may be necessary for samples to be provided for research, so we collect from many individual plants to avoid harming the plant's future survival in the wild and do not harvest more than 20% of the available seed.
