Planting

Caption

Planting Abies religiosa (Sacred fir) seedlings under the shade of pre-existing shrubs (Senecio cinerarioides, narrow green-greyish foliage) as protective “nurse plants”. Large trees on background are adult Pinus hartwegii, the pine that reaches the timberline. Abies religiosa is completely absent in this site at 3800 m of elevation, northeaster slope of Nevado de Toluca volcano, central Mexico, because it is too high in elevation. Planters personnel are locals of Native Indian origin.
