In order to develop an efficient and effective conservation strategy using complementary in situ and ex situ techniques, we must have a clear understanding of each target species geographical distribution, its habitat preferences and requirements, its genetics, reproductive biology and taxonomy. The details of the localities where past collection have been made, the so-called passport data, associated with herbarium and germplasm collections, are a key source of information to guide future conservation activities. For example, if the passport data for a particular species indicates that it...

Conservation of globally endangered plant resources is a critical ecological, cultural and economic issue. The undertaking of ecological study focusing on the distribution, abundance and population structures of target species is fundamental to the assessment of the conservation status of wild populations. This is where geographical information systems (GIS) and their power and potential come into play. Geographical Information Systems (GIS) are one of the tools that allow the integration and analysis of large amounts of data sets. The integration of GIS in conservation programs can help...
