Oxford University Press.  \nPreface  \nScope and Aim  \nThis manual is intended to equip readers with the basic knowledge required to use Marxan version 2.43 and above (Ball et al., 2009) . We cover all the necessary data inputs, as well asthe steps required to successfully execute the program and interpret the results. We focus on the practicalities of using Marxan rather than the principles of reserve system design and optimization algorithms that solve the reserve system design problem. Some of this information is available in the appendices. In other cases, we attempt to direct readers to the appropriate sources. We provide some guidance to the sorts of problems Marxan can solve. It is important, however, to understand how Marxan works in order to avoid solving the wrong problem or misinterpreting the solutions. Marxan can be a very powerful tool, but if misused, it can provide misleading advice and undermine the credibility of systematic conservation planning.  \nCom plem entary Literature  \nWhere this manual seems light on detail or lacking in specific direction, additional information may be found in the Marxan Good Practices Handbook, available for download at [https://marxansolutions.org/](https://marxansolutions.org/ and)[ and](https://marxansolutions.org/ and) [https://pacmara.org/mgph-v2](https://pacmara.org/mgph-v2. This manual)[. This manual](https://pacmara.org/mgph-v2. This manual) and the Marxan Good Practices Handbook should be used together. This Manual and the Handbook provides the resources needed to undertake highly skilled and defensible analysis using Marxan. In addition, we strongly suggest reading some of the many peer reviewed articles that use Marxan in conservation applications. These articles demonstrate what types of questions Marxan is able to answer, how conservation problems are set up, the kinds of data that can be used, and how different objectives and constraints influence the resulting reserve solutions.  \nAcknowledgements on the update  \nFunding for this update to the Marxan manual was provided by a grant to The Nature Conservancy from Margaret A. Cargill Philanthropies to advance spatial action mapping and planning in conservation decision-making.  \nStanding Acknowledgem ents from 2018 version  \nPreparation of this version [version 1.8] of the Marxan manual has been as much a compilation exercise as a writing exercise and as a result, we owe a great deal of thanks to a large number of people.  \nFirst and foremost, a huge amount of credit must be given to Ian Ball and Hugh Possingham, the original developers of Marxan and authors of the previous manual. It is through their manual that both of us [E.T. Game and H. S. Grantham], and many others, have learned to use Marxan. Much of their original manual has been incorporated into this version, especially in the technical appendix.  \nWe also wish to acknowledge the significant contribution of Jeff Ardron.
