Along the Donets River in eastern Ukraine, the ground gives way to steep, pale slopes of chalk - the compressed remains of a Cretaceous sea that covered this land tens of millions of years ago. On these bright bluffs, which rise fifty to seventy meters and pitch as steeply as seventy degrees, grows a community of plants found almost nowhere else: specialists that have adapted to root in bare chalk, in blazing sun, on soil so alkaline and thin that most greenery cannot survive. This is the Chalk Flora Nature Reserve, and its very name announces what makes it precious - a flora that belongs to the chalk itself.

The mineral-rich, alkaline, fast-draining soil demands special tolerances, and over long stretches of time distinctive chalk-loving plants evolved to meet them - low, tough, often silvery-leaved species that thrive where ordinary plant...

The chalk slopes are too steep, the soil too poor and stony, for any farmer to make a field of them. Across the fertile black-earth belt of Ukraine, one of the most agriculturally productive regio...

Public access is prohibited. Its purpose is not recreation but preservation and scientific study - to leave this fragile chalk ecosystem as undistu...
