Pine marten DNA population study under way - BBC News

DNA samples from elusive pine martens are being collected as part of a study in the New Forest.

The rare mammals are now believed to be well-established and successfully breeding in the national park.

The elusive cat-sized member of the weasel family was previously only thought to have survived largely in the north of England.

Researchers are collecting genetic material in order to establish the health of the population in the forest.
