Compared to the magnitude of the problems this investment is small, but nevertheless it is considerable for an effort especially targeted at plants. In order to maximize the effect, a major tactic from the start was to design the programme to be catalytic, so as to provide other, larger bodies with the arguments and methods to work for plant conservation. This first phase of the programme has been a success, because it has placed plants on the international conservation agenda. Three main factors lie behind this preliminary success; one, the programme was realistically formulated from the beginning, building on the principles of the World Conservation Strategy and using the lessons learned from previous programmes of IUCN and WWF, such as the one on tropical forest conservation; two, a central coordination was ensured from the headquarters of IUCN and WWF; and three, some of the leading botanists of the world agreed to become involved by joining a Plant Advisory Group, which has contributed much in intellectual and scientific guidance.
Thus if 14-28% of these plants are used as drugs, and we accept the conservative number of higher plant species on earth to be 250,000, one can estimate that 35-70,000 species have at one time or another been used in some culture for medicinal purposes. If we are to discuss the global importance of medicinal plants, it is necessary to define the term medicinal plant. e. effects that relate to health, or which have been proven to be useful as drugs by Western standards, or which contain constituents that are used as drugs.
Thus there is a need to focus international attention on the conservation and sustainable utilization of medicinal plants, and a need to outline the principles and methods for implementing suitable conservation policies. This is recognized by many countries. However, as mentioned above, the scientific and economic resources to do the job are often lacking where they are most needed; but those industrialized countries, who are gaining economically from the use and exploitation of these The IUCN-WWFPlants Conservation Programme 21 resources have an obligation to assist and collaborate in conserving the living resources and have also a self-interest in doing so.
