GB/T 45140-2025 Technical guideline for monitoring and effectiveness evaluation of mangrove ecological restoration
1 Scope
This document provides a guideline for workflow for monitoring and effectiveness evaluation of mangrove ecological restoration, data collection and analysis, determination of ecological monitoring and effectiveness evaluation indicators, ecological monitoring plan, and restoration effectiveness evaluation.
This document is applicable to the monitoring and effectiveness evaluation of mangrove ecological restoration within the sea areas under the jurisdiction of the People's Republic of China.

3 Terms and definitions
For the purposes of this document, the following terms and definitions apply.
3.1
mangroves
a plant community mainly composed of mangrove plants, distributed in the intertidal zone of tropical and subtropical regions
3.2
mangrove ecological restoration
process of promoting the formation of a stable ecosystem with similar ecological functions to the original mangroves through measures such as eliminating stress factors, improving habitat conditions, and artificially introducing mangrove plant propagules/seedlings in areas where mangroves have degraded or been lost
3.3
survival rate
percentage of the number of surviving seedlings in the restoration area to the number of seedlings initially planted
3.4
preservation rate
percentage of the number of seedlings that still grew normally during the monitoring period after the successful planting of seedlings in the restoration area to the number of seedlings initially planted
4 Workflow
4.1 The monitoring and effectiveness evaluation workflow of mangrove ecological restoration includes four steps, namely, data collection and analysis, formulation of ecological monitoring and effectiveness evaluation plan, implementation of ecological monitoring, and restoration effectiveness evaluation, as shown in Figure 1.
