Sadly, in the case of any life form that is either very rare or near extinction, there are always some B*****ds who will collect it for their own pleasure. It's not just the amateur enthusiast that is to blame, so called professional naturalists do it as well. E.G. A friend of mine owns a good number of acres of land in the Derwent Valley which forms the boundary between Northumberland and durham. This land is posted as Private and there is no public right of way over it or Bridle paths.
As it happens a very rare Helliborine existed on this land and it was the only known plant of this species known in Northumberland. He was asked to lead a very small party of botanists from a Local Natural History Society on a walk over his land. He did show them this particular plant, he emphasised it's scarcity and asked these people not to reveal its location. (It was in a difficult position to find). Two days later he went to examine this plant and found that it had been 'dug up' and removed. Only one of the people who had been shown its location could have found it.
This only goes to show, that where a rare species of any life form is found, it pays to keep it secret. Show people photographs by all means, but never ever reveal the location.
Plants are not 'my bag', I am an entomologist, after ten years of research I have, in my home county of Northumberland located 165 sites where the Large Heath Butterfly can be found breeding. This total is four times larger than all the known sites of this species in the rest of England and Wales.
I, when asked where this species can be found, will only give the names of sites that are already in the public domain. I have been accused of elitism because of my attitude, but, if I took the time and the trouble to get off my backside to go out and find these sites, others can do the same if they want to see this insect.
I'm afraid I have no time for 'twitchers' of any variety, I have learned from bitter experience, that not all 'so called' naturalists are to be trusted. If you have a rarity in your area, keep it to yourself, that way it may survive. Tell someone, and it's likely that whatever you have found, will soon be gone.
Sadly the old joke of the big Game hunter, on being told that the White Rhino was becoming very rare, ordered his butler to book a safari immediately, exclaiming, "I have to bag one before they become extinct". Unfortunately this attitude does not only apply to Big Game Hunters.
