  1. Developing better support materials for Marxan and its future developmentsThe New Marxan Manual Jeff ArdronVice-President Pacific Marine Analysis and Research Association (PacMARA) Vancouver, British Columbia, Canada Applied Environmental Decision Analysis Commonwealth Environmental Research Facility The Ecology CentreThe University of QueenslandSt Lucia, Queensland, Australia MEBM Tool Innovation Fund project, EBM Tools Network, 12 Feb 2008 (13 Feb in Australia) Marxan Manual Launch

  2. The Team Writers:Eddie Game & Hedley Grantham Editors:Jeff Ardron, Carissa Klein, Dave Nicolson, Hugh Possingham, & Matt Watts New-user testers: Lindsay Kircher & Dan Segan Spanish translation supervisor: Jose (“Pepe”) L. Gerhartz Wiki development: Kyira Korrigan Marxan Manual Launch

  3. HistoryThe plea for a Systematic Approach... Margules, C.R., and Pressey, R.L. (2000). Systematic conservation planning. Nature, 405: 243-253. “A more systematic approach to locating and designing reserves has been evolving and this approach will need to be implemented if a large proportion of today’s biodiversity is to exist in a future of increasing numbers of people and their demands on natural resources.” Jeff Ardron, PacMARA

  4. Non-optimal Decisions in the past? --terrestrial Gonzales, E.K., Arcese, P., Schultz, R., & Bunnel, F. (2003). Strategic reserve design in the Central Coast of British Columbia: Integrating ecological and industrial goals. Canadian Journal of Forest Research. 33, 2129-2140. Jeff Ardron, PacMARA

  5. Non-optimal Decisions in the past? --marine Klein, C.J., Steinback, C., Scholz, A.J., Possingham, H.P. In review. Effectiveness of marine reserve networks in representing biodiversity and minimizing impact to fishermen: a comparison of two approaches used in California. California Marine Life Protection Act Initiative Marxan Solutions Fishermen Conservationists Mixed Solution considered Jeff Ardron, PacMARA

  6. Where site selection tools fit into the larger picture... Software & systematic planning • Scope and cost • Identify and involve stakeholders • Identify goals • Compile data • Set conservation targets • Assess existing conservation areas • Select new conservation areas • Implement conservation action • Maintain and monitor Slide Courtesy Bob Pressey

  7. Developing Good Practices www.pacmara.org Jeff Ardron, PacMARA

  10. Strengths of Marxan Flexibility / variety of options (62%) Handling of large amounts of data (30%) Near-optimal solutions (25%) Repeatability/ transparency (19%) Summed solutions (17%) Reputation (13%) Speed (13%) Explicit targets (11%) Inclusion of costs (11%) Systematic approach (11%) Ability to create graphical outputs (9%) Ease of use (9%) Slide: Natalie Ban Jeff Ardron, PacMARA

  11. Weaknesses of Marxan Insufficient guidance for adjusting settings (43%) Errors/bugs (39%) Preparing the input files (37%) Steep learning curve (16%) Converting outputs to GIS (14%) Interpreting/explaining results (14%) User interface (12%) Determining input targets/features (10%) how parameters interact (10%) Defining cost parameter (8%) Slide: Natalie Ban Jeff Ardron, PacMARA

  12. Addressing the weaknesses:Developing Good Practices (Globally) Marxan Good Practices Workshop 2-5 April 07, UBC, Vancouver, Canada • Part 1: linking EBM tools to decision-making (~110) • Part 2: Marxan BP Handbook drafting groups (~24) Jeff Ardron, PacMARA

  13. Outcomes: Revised Marxan Manual and Good Practices Handbook • Manual in partnership with U Queensland Ecology Centre, funded by Packard Foundation, thru Duke U. Feb 2008. • Handbook relying on volunteer experts to write chapters. Some funding (Moore Foundation) to pull it all together. March 2008. • Case studies: showcasing of regional projects (e.g. BALANCE) more funding needed... Hugh Possingham, Australia Gunter Forsterra, Chile Xinhai Li, China Baltic BALANCE-HELCOM Ecological Coherence Workshop, Helsinki, Oct 07 Jeff Ardron, PacMARA

  14. Marxan, where next?--Hugh Possingham, FAA • Marxan is incredibly well used • Peer-reviewed science is critical • Marxan costs us lots of money to service, maintain and develop • Lots of new things on the horizon • Great job Eddie and Hedley plus funders • Next task is to write up user-friendly case studies - needs a year of $ plus travel Marxan Manual Launch

  15. Software Development • Marxan optimised (v. 2.0.2 – free, online now) • Marxan with zones • Probabilistic treatments…threats, species distributions, etc. • Connectivity • Cluster analysis of Marxan solutions • Training courses, new website www.ecology.uq.edu.au/marxan/ Marxan Manual Launch

  16. Acknowledgements • Australian Department of Environment and Heritage • Australian Natural Heritage Trust • EcoTrust • New Zealand Department of Conservation • Ontario Ministry of Natural Resources • The Nature Conservancy • University of California • University of Queensland Marxan Manual Launch

  17. The New Manual(talk by Eddie Game & Hedley Grantham) Free pdf download web sites: UQ Ecology Centre http://www.ecology.uq.edu.au/marxan.htm (easier to just Google “Marxan”) ...and PacMARA: www.pacmara.org Marxan Manual Launch

  18. Wrap-up: Jeff Ardron • A new manual (at last!): download with software or at PacMARA site (pacmara.org) • Getting started: Ch. 2, Appendix C, & Marxan 101 http://www.ecology.uq.edu.au/marxan.htm • The PacMARA Wiki experiments: Manual (now) and Good Practices Handbook (~March) • Spanish translation: ~March • The Marxan Good Practices Handbook: being edited by Hugh and Jeff, due out in March… (Watch for it!) Marxan Manual Launch

  19. Acknowledgements Thanks to our funders: MEBM Tool Innovation Fund(Packard Foundation, administered through Duke University) Thanks to the EBM Tools Network, esp. Sarah Carr, for hosting of the launch and finding a service that could take hundreds of participants... Thanks to Natalie Ban, Carissa Klein, and Bob Pressey for the use of their images / slides. Thanks to the whole team for making it happen across three continents and 18 hours in time zones... Marxan Manual Launch
