The composition and productivity of two mangrove sites surrounding the Laguna de Terminos, Mexico, were studied from March 1979 to January 1984. Measurements were made of the tree composition, above-ground woody biomass changes, and litterfall production at a high-salinity fringing site and a low-salinity riverine site. Rhizophora mangle L. was the dominant tree at the fringing site, but occurred only at the water's edge at the riverine site. Avicennia germinans L. dominated the inland area of the riverine site. Laguncularia racemosa Gaertn. f. had a more even distribution from shore to inland and from site to site. Average diameter at breast height (DBH) was greater at the riverine site for each of the three species; however, tree density (trees > 2.5 cm DBH) was more than twice as high at the fringing site (7510 ha −1 ) than at the riverine site (3360 ha −1 ). Wood production (1206 g m −2 year −1 vs. 772 g m −2 year −1 ) and litterfall (1252 g m −2 year −1 vs. 835 g m −2 ) were higher at the riverine site than at the fringing site. Total estimated above-ground net production was 2458 g m −2 year −1 at the riverine site and 1607 g m −2 year −1 at the fringing site. |
