Abstract

The AA. measured accumulation rates of sediment in 6 cores from marl- and sand-based marshes of northern Belize and compared biogeochemical characteristics to assess recent wetland history (- 1850 to present). Sediment depth increments were analysed for bulk density, LOI, nutrients, snail shell density and species diversity. Cores were dated. Increased sediment accumulation by human activities such as soil washout from adjacent roads was recorded in a sand-based marsh near roads. Sediment cores in the marl-based marshes display changes of marsh vegetation, apparently caused by water level changes at the end of the 1800s
