Summary

There are two fundamentally distinct conservation strategies, in situ and ex situ that are distinguished based on whether the target taxa are conserved where they are found or are sampled and moved to a secondary location to be conserved. Within the two strategies there are a range of in situ and ex situ techniques, each of which aims to maximize the range of plant genetic diversity maintained. There are advantages and disadvantages associated with each strategy and technique. The two strategies for conservation, in situ and ex situ, complement each other and the mixture of strategies and techniques employed to conserve a target taxon will vary from taxon to taxon depending on its characteristics and the resources available to conserve that taxon.
