Abstract

The success of ecosystem restoration depends on a multitude of factors related to both the properties of the ecosystem and resources available for the restoration. The ecological and management characteristics of the site may influence the success of restoration, including the presence of invasive species or existing and continued management practices. Key to the ability to assess success of restoration is monitoring, which is increasingly being undertaken using remote sensing technology. In this chapter, we focus on invasive species management to restore intertidal wetland vegetation, and present a case study from North Queensland, Australia, where exclusion fences have been constructed to control feral pigs and restore intertidal vegetation. Physical vegetation sampling using quadrats and unmanned aerial vehicle (UAV) imagery were used to determine vegetation change at five sites using image classification and ground truthing. Wetlands were fenced in an attempt to prevent feral pigs accessing the sites, but was ultimately unsuccessful owing to existing management practices allowing cattle to graze in fenced wetlands, which presumably allowed feral pig access. Learnings here suggest that restoration initiatives cannot be implemented without first considering existing land management practices and how the two interact or compete with each other. While the use of UAV technology was useful for monitoring, restoration projects still need to be carefully designed with the ecological and management practices in mind in order to be successful.
