this, and maggi's comments, make me think of a tv show i saw not long ago, which attempted to retrace the journey of a tiger in india, which had been documented and filmed extensively in a tiger reserve, then left the reserve and was found killed by a train far out of the area where tigers were expected..
the filmmakers realised in the journey that in fact this was not a weird place for a tiger to have gone, but rather followed a natural corridor which should have been home to tigers, but where they had been exterminated;
at least partly as a result of the publicity of the film/story, several points along that route have been made into parks, and programs to restore tiger populations are underway/consdideration..
the relevance is that the filmakers raise the point that iconic species can be vital to conservation, since it is very difficult to excite the average person about a rodent, insect or tiny plant, but if you can get them behind the preservation of a charismatic animal, the entire ecosystem may be preserved; in this case, the fate of an entire forested region is considered to be tied to the fate of the tiger, and subsequently the fate of the watersheds and the people who live there! there are no doubt many wonderful plant species in this area which will go along for the ride--whichever way it goes!
