High Brown Fritillary (HBF)
The Primary larval foodplants were Common Dog violet (viola riviana)
and hairy violet (viola hirta)
Ref: ukbutterflies.co.uk
My thoughts before visiting above site:
Where land owners did not propagate Violets by root division, and butterfly conservationists were not allowed to uproot wild flowers, because of UK laws, better awareness relationships needed to be made with land owners (which might have been Governmental Organisations).
Violet strains
The plants most frequently chosen by HBF to lay on, might have, over many generations of caterpillars, become scarcer. Some of those remaining favourites, needed to be specifically given an official propagation & growing programme by someone, away from a population of HBF, so that many more native plants could be introduced later into suitable habitat.“

Re: “Violet Slump hits rare Fritillary”
I know you cannot - quite right too - uproot wild plants. But is there a prohibition against collecting seeds?
