Preservation of the habitat is the only logical strategy to save endangered species from early extinction. Ecological amplitudes of rare species are very narrow, so transplantation to such alien sites as botanical gardens is not a solution. Protection may not be the answer. We must learn as much as we can about the biology of the species in question, in the field and under laboratory conditions. The first steps must be to determine the distribution. This would be followed by analysis of soils by means of physical and chemical studies. Pollination ecology, associated species, phenological records, and genetic and cytological studies must be a part of the biological studies. Such studies would require teamwork by qualified botanists.
