DISPERSIÓN DE SEMILLAS DE Pseudotsuga menziesii EN POBLACIONES DEL CENTRO DE MÉXICO Pseudotsuga menziesii SEED DISPERSON IN POPULATIONS OF CENTRAL MÉXICO

Pseudotsuga menziesii is a valuable tree in silvicultural production around the world. In Mexico it is found at the southernmost limit of its natural distribution, but its capacity to disperse seed, which helps in its regeneration, is unknown. In this study, quantity and period of seed dispersion was studied in four contrasting natural populations of P. menziesii (Douglas fir) in
