Dr Frans Vera (born Franciscus Wilhelmus Maria Vera; Amsterdam, 4 June 1949) is a Dutch biologist and conservationist. He has played a key part in devising the current ecological strategy for the Netherlands. He has hypothesised that Western European primeval forests at the end of the Pleistocene epoch did not consist only of "closed-canopy" high-forest conditions, but also included pastures combined with forests, a hypothesis variously addressed as the Vera hypothesis or the wood-pasture hypothesis.
