Trade-off between tree planting and wetland conservation in China

Y. Xi, S. Peng, et al.

This study reveals how tree planting in China from 2000 to 2016 has led to significant wetland loss, particularly in the dry northern and western regions. Researchers Yi Xi, Shushi Peng, Gang Liu, Agnès Ducharne, Philippe Ciais, Catherine Prigent, Xinyu Li, and Xutao Tang underscore the importance of spatially optimizing tree planting efforts to protect vulnerable wetland areas while still enhancing carbon sequestration.

Abstract
This study investigates the impact of tree planting on wetland dynamics in China from 2000-2016 and projects potential impacts for 2017-2035. Using satellite data and a land surface model, the researchers find that historical tree planting over wetland areas has resulted in a net wetland loss. The dry northern and western regions show higher sensitivity to wetland reduction from tree planting than the moist southern regions. Continuing tree planting scenarios are projected to lead to significant wetland loss in protected wetland reserves. The study highlights the need for spatial optimization of tree planting to balance carbon sequestration and wetland conservation.
