As habitat conservation is arguably the most important aspect of species 
conservation, the 101 species of conservation concern were assigned to 
the habitats on which they mostly depend. These data are presented in 
Table 3. Broadly, this shows the importance of the highlands (in which 
most of the endemics occur), the uncultivated areas of the Tihamah, and 
the offshore islands which are the home of breeding seabirds. Unlike 
many other parts of the world, freshwater wetlands are relatively 
unimportant, but where they occur they act as a magnet for wildlife 
simply because they are at a premium. 
I do not wish to comment further at this stage. One of the aims of the 
OSME survey of southern Yemen in spring 1993 is to collect data to 
enable further examination of this provisional list.
