Abstract

Adaptive management theory has attracted substantial interest in recent years, in natural resource management in general and also for invasive alien species management. However, whilst many theoretical and conceptual advances have been made, documented cases of practical applications are rare. Coupling invasive species management components with adaptive feedback processes is not without challenges, requiring a substantial change in the thinking and practice of all those involved. Drawing on a decade of experience in South African National Parks, we suggest an approach to implementing adaptive management for controlling invasive alien species. Whilst efforts have been made to advance components of the overall management strategy, the absence of a framework for decision making and feedback mechanisms, inflexibility in the system and shortcomings in the governance structure are all identified as barriers to learning and knowledge integration for the purposes of effective invasive alien species management. The framework provided here, encompassing documents, committees and processes, is aimed at addressing these shortcomings. Conservation implication: Adaptive management theory offers a robust tool for managing inherently complex systems. Its practical application, however, requires distilling the theory into useable functions. We offer a framework to advance implementation of strategic adaptive management for the control of invasive alien species using experiences gained from South African National Parks.

Highlights

Ecosystems are dynamic, changing in both space and time and over multiple scales (Pickett, Cadenasso & Benning 2003)
Strategic adaptive management (SAM), as applied in SANParks, encompasses the general Adaptive management (AM) process, but differs by focussing more explicitly on (1) developing a mutual understanding and appreciation by stakeholders of the way ecosystem goods and services are valued, (2) building an understanding of the social, technological, economic, environmental and political context and (3) establishing an adaptive assessment process for defining spatially and temporally explicit monitoring programmes that assess the response of ecosystems to management actions (Biggs & Rogers 2003; Roux & Foxcroft 2011)
We suggest that greater focus on the governance structure of invasive alien species management is required for improved utility of the framework we present

Summary

Introduction

Ecosystems are dynamic, changing in both space and time and over multiple scales (Pickett, Cadenasso & Benning 2003). Frameworks for implementing SAM for alien species management have been proposed (Bestbier et al 2000; Freitag-Ronaldson & Foxcroft 2003), emphasis has been largely on developing specific TPCs to date.
