Collection of systematic status & trend data improves our effectiveness to:

• Track and assess trends in the status of biodiversity

• Assist in demonstrating impact of actions and investments on biodiversity

• Justify and direct future conservation, policy and investment decision making

• Communicate successes and failures of conservation strategies to government agencies, investment bodies, industry and society as a whole.

• Better understand the dynamics of biodiversity components and threats and adapt accordingly.

• Contribute to international biodiversity status reporting, e.g. Convention on Biological Diversity and the Millennium Ecosystem Assessment.



Indicators, defined regionally for Madagascar, are globally transparent measures that contribute to CBD recommendations and the Millennium Development Goals.

• Core Indicators:– Change in Red List status of threatened species– Protected status of Key Biodiversity Areas– Change in habitat cover of Key Biodiversity Areas– Fragmentation of habitat in corridors

• Additional intervention measures:– Number of safeguarded key biodiversity areas with governance structures &

management plans– Percentage of globally threatened species that have ongoing studies that focus

on ecology, population, or distribution & monitoring in place

Change in Protection Status of Conservation Priority Areas: Key Biodiversity Areas, including Alliance for Zero Extinction Sites

Trends in the total percentage of the defined key biodiversity areas (KBAs) and AZE

sites under some form of legal protection for the time period 1996 – 2006.



Protected status of KBAs

GREEN = Protected KBAs (n=50)

RED = Unprotected KBAs (n=114)

2006: 30.5% of all 164 KBAs including 11 of 15 AZE sites (73%) benefit from official safeguard status

164 Key Biodiversity Areas identified by CI and partners based on multiple taxonomic groups (IBAs, IPAs, KBAs)

Decision-making:

How can biodiversity information be best utilized by government and investment decision makers to guide strategic conservation & sustainable development planning?

• What scale of conservation decision making (site, regional & national) and by whom?

Reporting:

Can a subset of selected CBD indicators recommended for measuring the 2010 target be adopted to track & report progress at national and regional scales?



Establishing National/Regional Monitoring networks to ensure consistency and sustainability in data collection and reporting.

Monitoring systems held together by five components:

• Key stakeholders with defined technical roles & responsibilities

• Complementary indicators with standardized measurement protocols

• Centralized & compatible data housing and analysis infrastructures

• Collaborative dissemination efforts (workshops, publications)

• Fundraising strategy driven by multiple partners
