I am new in cp. I am a Colombian Biologist working in biotechnology, and 
although dealing at present with passionflowers and tree ferns, my main 
interest focuses on biotechnological means <examples, case studies, 
special reports> to conserve threatened tropical plants such as some CP <I 
suppose there must be some>.
Some body told me that some years ago there used to be a very common cp in 
the Colombian Andes, above 3500 m in elevation, until an exotic grass, 
Pennisetum clandestinum <in spanish called Kikuyo>, was introduced.
This grass grows sow quickly and invades in such a way that the cp went 
almost extinct.
Does somebody know what am I talking about _
