Temporal Changes in Land Use Dynamics and Mangrove Expansion in the Guandu Wetlands, Taipei, Taiwan

Abstract

Effective conservation of wetlands requires long-term monitoring and evaluation, yet this critical step is often overlooked. This study aims to assess the changes that occurred in the Guandu Wetlands in Taiwan by quantifying land use and land cover between 2007-2018 and 2018-2021. Investigation revealed a total change (including gains, losses, and swaps) of 57.1% from 2007 to 2018, and 32.7% from 2018 to 2021. Notably, the dynamic variations within low-density, medium-density, and high-density mangrove categories were highlighted, with high-density mangroves showing the most significant gains (28.3 and 12.6 %) across both periods. By focusing on preserving and effectively managing the Guandu Wetlands in Taipei, Taiwan, this study serves as a compelling case study that may be applicable to wetlands more widely. The dynamic nature of mangrove ecosystems emphasizes the critical importance of informed conservation and adaptive management strategies. This research contributes to advancing understanding in this field, advocating for proactive measures to safeguard wetland ecosystems.
