In the Estero Palo Verde, located in section IV of the Cuyutlán Lagoon, state of Colima, 48 sample units (SU) were established on three types of mangrove stands: 10 SU on pure stand of Laguncularia racemosa, 25 SU on pure stand of Rhizophora mangle and 13 SU on mixed forest stand of L. racemo- sa-R. mangle. Canopy height, trunk diameter, density of adults and natural regeneration were recor- ded, also basal area and tree volume were calculated. Results indicated that density, basal area and tree volume for diameter category (DC) of 5 cm were significantly (P < 0.05) different between the pure stands of R. mangle (2500 trees·ha-1, 4.2 m2·ha-1, 22 m3·ha-1) and L. racemosa (700 trees·ha-1, 1.9 m2·ha-1, 10 m3·ha-1). In the case of DC of 20 to 30 cm, the basal area was significantly (P < 0.05) higher in the pure stand of L. racemosa (1.6 – 3.8 m2·ha-1) than in the mixed forest stand of L. racemosa-R. mangle (0.5 – 2.5 m2·ha-1). Natural regeneration was more abundant in the stand of R. mangle (138 – 270 individuals·ha-1) than in the stand of L. racemosa (70 – 80 individuals·ha-1). The highest structural values were reached for canopy height (10 m) in the stand of L. racemosa, for trunk diameter (40 cm) and basal area (14.1 m2·ha-1) in the stand of L. racemosa-R. mangle, and for natural regeneration (624 individuals·ha-1) in the stand of R. mangle.
