Lemur protection

User: Heather Peacock, MSc Thesis for Dept. of Geography, University of Calgary, Alberta, Canada

Marxan was used to assess the protected area network in Madagascar for lemur conservation. This involved predicting lemur distribution with an extention of Marxan - Maxent Species Distribution Modelling software, designed an optimual reserve network for the lemurs, comparing that to the existing network, then prioritising wher the network needed expansion to meet conservation targets.

Achieving Balance

Marxan, ArcGIS and Zonation were used extensively in a spatial analysis designed to integrate the management of land, water and resources, including fish, wildlife and their habitats. First to take place was consultation with First Nations, other residents, stakeholder groups and experts to determine issues, interests, and considerations in the Peel Watershed Planning Region. Then conservation values and interests and their indicators were identified, their spatial distribution described and critical issues defined. Finally, the results of spatial analysis were distilled into sets of conservation priorities.

These conservation priorities were then compared and contrasted with other regional conservation initiatives, and their influence on the regional planning process was discussed.

Rezoning the reef & Pacific Island Conservation

GBReef morguefile CCMarxan was redeveloped in order to assist in the rezoning of the Great Barrier Reef, Australia, and was also used to quantify the tradeoffs between conservation and socio-economic factors in the Pacific Islands.

An international standard is to conserve 20% of all habitats by 2012. When planning conservation in the small Pacific Islands, the context is more unique due to their small size and heavy reliance on fishing and resources from the coral reefs. Compromises/tradeoffs are expected then, for both conservation and socio-economic /fishing. Marxan was used to be able to, for the first time, quantify these tradeoffs, and work out the optimal balance for conservation in the Pacific.

National Park Extension

Zebra Morguegile CC

Marxan was used to assess the feasibility of expanding the Mt Zebra National Park (MZNP), South Africa.

User: SANParks, Mount Zebra National Park, Africa.

The expansion has created a massive reserve for zebra, elephants, buffalo, big cats and many more animals. It also helped to connect MZNP to other parks, forming a corridor for wildlife and at the same time protecting native grassland habitats.
