Data Analysis & Interpretation
Data analysis and interpretation are part of the evaluation aspect of adaptive management, the process for conserving, protecting, and, where appropriate, restoring lands, waters and other resources in a protected area. Adaptive management is often defined as a system of management practices based upon clearly identified outcomes, where monitoring evaluates whether management actions are achieving desired results (objectives). Adaptive management is a decision process that promotes flexible decision making that can be adjusted in the face of uncertainties as outcomes from management actions and other events become better understood through data analysis and interpretation.
Adaptive management accounts for the fact that complete knowledge about fish, wildlife, plants, habitats, and the ecological processes supporting them may be lacking. The role of natural variability contributing to ecological resilience also is recognized as an important principle of adaptive management. It is not a “trial and error” process, but rather emphasizes learning while doing based upon available scientific information and best professional judgment considering site-specific biotic and abiotic factors in protected areas. Adaptive management results in effective monitoring and evaluation of a protected area management plan.
For many protected area practitioners, data analysis and interpretation can be a daunting task. Often, resources and training are provided on the practical aspects of monitoring without much guidance on how to analyse and interpret the data for adaptive management. However, there is little point in collecting data unless you have plans to use that data for communication and/or adaptive management purposes and it is therefore very important to acquire some skills in this area.
Below are some key resources that can be used by practitioners prior to designing monitoring programs right through to the process of adaptive management. For those who have time and are truly invested in understanding data analysis, Houk’s (2010) guidebook is highly recommended. Beneath the data analysis guidebooks are a short list of references for statistical analysis.
U.S. Department of the Interior. 2009. Adaptive Management: The U.S. Department of the Interior Technical Guide.
The purpose of this technical guide is to present an operational definition of adaptive management, identify the conditions in which adaptive management should be considered, and describe the process of using adaptive management for managing natural resources. The guide is not an exhaustive discussion of adaptive management, nor does it include detailed specifications for individual projects. However, it should aid protected area managers in determining when and how to apply adaptive management.

CoReMo software was developed by ARVAM with support from the French Overseas Ministry, Réunion Regional Council and the EU, and in close collaboration with the WorldFish Center, Penang, Malaysia. The software is fully interoperable with ReefBase and FishBase.
CoReMo 3 is designed to help users enter and analyse data collected using the methods and protocols outlined in Methods for Ecological Monitoring of Coral Reefs.
Feinsinger, P. 2001. Designing Field Studies for Biodiversity Conservation. Island Press.
This book explains how to undertake field studies to guide conservation work and is for anyone working in conservation regardless of their professional or scientific background. The methods and procedures of scientific inquiry are explained in a step-by-step manner. The author wants to make the process of doing science accessible and effective. The purpose of this book is not only to offer information, but primarily to catalyze the process of good thinking, so that readers can learn how to think and understand the importance of broad inquiry, no matter what the conservation project.
Pomeroy, R.S., Parks, J.E., Watson, L. M. 2004. How is your MPA Doing? A Guidebook of Natural and Social Indicators for Evaluating Marine Protected Area Management Effectiveness. IUCN Gland, Switzerland and Cambridge, UK.
Chapter 3 (pages 30 – 35) of this handbook contains a description of managing MPA data once it has been collected. It discusses the various steps of data coding, storage, entry and runs through the various types of exploratory statistics that are possible. There are brief descriptions of further analysis options. The chapter concludes with a discussion of the importance of ascertaining internal and external evaluation of results.

Reef Check provides excel spread sheets with built in macros for carrying out preliminary data analysis. Pages 31-36 of their manual have illustrated instructions for how to correctly complete the spreadsheets with explanations of the output data.
There is also a chapter discussing data analysis that explains how to interpret the results including the meanings of the standard error and the standard deviation.
Wilkinson, C., Hill, J. 2004. Methods for Ecological Monitoring of Coral Reefs. A Resource for Managers. Australian Institute of Marine Science, Townsville, Australia and Reef Check, Los Angeles, USA. 117pp.
There is a section on data handling and storage of results on page 14 of this resource. It covers data storage, analysis and reporting. There is also a discussion of the importance in involving the public in the dissemination of the results which can be a key factor in determining the success of protected areas.
