Biomass distribution in declining sacred-fir seedlings

In the forests located west and southwest of Mexico City, declineof sacred-fir Abies religiosa (H.B.K.) Schl. et Cham. hasbeen observed for the past 25 years. Characterization of thephenomenon from different viewpoints is important if knowledgeof the problem is to be increased and viable solutions p...
