Effects of land-use and hydroperiod on aboveground biomass and productivity of secondary Amazonian floodplain forests
Tropical floodplain forests are productive and diverse ecosystems for which there is scant data on biomass, carbon sequestration, and potential abiotic and human drivers. We used a regression approach to test the effects of seasonal flood duration, forest age, and livestock activity on aboveground b...

Tropical floodplain forests are productive and diverse ecosystems for which there is scant data on biomass, carbon sequestration, and potential abiotic and human drivers. We used a regression approach to test the effects of seasonal flood duration, forest age, and livestock activity on aboveground biomass (AGB) and annual biomass accumulation (ABA) in 49 plots of 0.1ha in secondary floodplain forests of the Lower Amazon over nine years. AGB averaged 226±87Mgha-1 among forests 30-120years old. An intermediate peak model explained spatial variation in AGB, peaking in moderately flooded (70-140dy-1) forests. Flood duration was the key explanatory factor for AGB across all plots. In contrast, forest age and its interaction with flood duration affected net ABA, which declined from 10.3±4.3 to -6.2±11.1Mgha-1y-1 with increasing age. Tree diameter growth comprised 95±4% of total ABA, which declined with increasing flood duration and increasing forest age. Overall, forests had a high capacity to capture carbon, accumulating 16.4±7.1Mgha-1y-1 in AGB, but had high turnover of biomass at 76±81% of AGB per year. There was no strong evidence for differences in biomass accumulation due to livestock activity. We fill a major geographical gap for ground-based data on biomass of flooded forests, which comprise 11% of the Amazon Basin, and also provide an example of community-based monitoring for carbon storage in human-dominated tropical floodplain ecosystems. © 2014 Elsevier B.V. |
