The Aleppo Pine Forest of Mont Boron

This entire forest exists because a 19th century engineer refused to give up on bare rock. When Nice became French in 1860, the summit of Mont Boron was heathland, stripped of tree cover by centuries of grazing and cutting. Forester Prosper Demontzey, who later became one of France's most influential figures in mountain reforestation, took on the hillside in 1862 and tried sowing Aleppo pine seed directly into the exposed ground first. It failed repeatedly. What worked was planting young pines into deep, prepared holes instead, a labour-intensive method that eventually caught, and the pine cover that established itself went on to shelter the return of olive and carob trees beneath it as the canopy matured. The forest today covers 57 hectares with eleven kilometres of marked trails, wrapping around the villas that Second Empire figures like Baron Haussmann built on the hill once it was fashionable and shaded again. No individual tree from Demontzey's original planting is identified as still standing, so any age given describes the reforestation campaign rather than a specific measured pine.
