Spanning over 1,400 square miles, Yorkshire's two national parks are vibrant enclaves of natural beauty year-round. In springtime, the dales and moorland burst into life, with both animals and plants preparing for the long year ahead. As the seasons change, so do the lives of the parks' inhabitants. Throughout all four seasons, cameras capture intimate moments tucked away from human sight as the untouched nature reserves teem with life, even though the parks see some 20 million visitors every year.
