Abstract:

Conventional assessment of wetland conservation/restoration effects usually involves monitoring of multiple variables and requires interdisciplinary expertise in biology, environmental sciences and socioeconomics. As China is putting huge efforts into restoring degraded wetlands, fast and cost-effective methodologies for quantitative assessment of the conservation effects are crucial and in great need. For three years, we studied a former paddy field that was recently rehabilitated to a forested wetland in Yunqiao, southwest China. Floristic Quality Assessment Index (FQAI) was used as an ecological indicator to monitor rehabilitation progress with repeat yearly samplings of plant species information along four parallel fixed line-transects in the wetland. The conservative values were calculated for each species based on evaluation of all wetland plants in the floristic area. The results showed that both the mean coefficient of conservatism (CCmean) and the FQAI increased significantly, while no clear trends were presented by the species diversity indices (Shannon-Wiener index, Simpson index, Pielou index) over the three year sampling period, suggesting FQAI is a promising and effective ecological indicator for rapid and quantitative measurement of vegetative rehabilitation effects in wetlands.
