in the Tropics?

The Challenge: Reduction of biodiversity loss by 2010
• Reduction of biodiversity loss by 2010 is amongthe most ambitious targets of the Johannesburg 2002 summit.
• The European Union is most ambitious by aiming at a total halt of biodiversity loss

The Challenge: Reduction of biodiversity loss by 2010
• Reduction of biodiversity loss by 2010 is amongthe most ambitious targets of the Johannesburg 2002 summit.
• The European Union is most ambitious by aiming at a total halt of biodiversity loss
• The European Union does comprise tropical areas

Good News
• Political target:
Ecologists and Environmentalists are not alone

Good News Bad News
• Political target:Ecologists and Environmentalists are not alone
• How do we measure loss?Where is the baseline?
• Implementation:Even if we know loss: how do we stop it?

The Extraterrestrial Consultant:
The Martian aks about:
Purpose of monitoring,
Magnitude and distribution of benefits,
The Martian finally concludes that benefits from Biodiversity are large.
22/02/2007 Gtoe 2007
The Extraterrestrial Consultant:
The Martian did not ask a fundamental question:
How many species on earth?
Do we have a list?

The Martian did not ask a fundamental question:
How many species on earth?
Do we have a list?
Or an illustrated catalogue?

The Problem:
Diversity in the Tropics is overwhelming
(gu)estimates from canopy studies:
30 million Erwin
80 million Stork
Consensus:
appr 5 million

Good News Bad News
• More than 5 million species on Earth
• „only“ 1.8 million described
• Taxonomic impediment
• Unprecedented species loss: many species probably disappear before they are described
22/02/2007 Gtoe 2007
Good News
• A well-established assessment scheme by the IUCN Red List

Good News Bad News
• A well-established assessment scheme by the IUCN Red List
• IUCN criteria not applicable to many tropical species only known from singletons
• Actual rate of species loss is a (gu)estimate,
• …but definitely around 1000 times higher than natural extinction rates

Global Amphibian Assessment
The GAA assessed threat status and distribution for each of the
5,743 amphibian species known to science.
More than 520 scientists from over 60 countries contributed to the three-year study.
Results provide a baseline for global amphibian conservation, and will be used to design strategies to save the world’s rapidly declining amphibian populations
The Panamanian golden frog is one of roughly 110 species of harlequin frog (Atelopus), many of which are dying out. Although this species still
survives, its numbers have fallen significantly.

RAP, CAMP & TEAM & (ATBIs)
RAP scientists gather and report information about:
•Vegetation structure and richness•Birds•Mammals•Reptiles•Amphibians•Selected insect groups
RAP conducts terrestrial biodiversity surveys in Central and South America, the Asia-Pacific region, and Africa.

The LPI is the average of three separate indices measuring changes in abundance of
555 terrestrial species,
323 freshwater species
267 marine species
around the world.

Good News
• Sufficient information is available for clear recommentdations to reduce biodiversity loss:
- protect primary forests- connect forest fragments- Implement sustainable tropical agriculture
22/02/2007 Gtoe 2007
Bad News
• Main drivers of tropical diversity loss continue or increase:- dams,- biofuel- climate change- biological invasions
• International Conventions not binding (CBD) or limited to few species (CITES, CMS)
22/02/2007 Gtoe 2007
Conclusion
There is societal consensus for „halt biodiversity loss“ by 2010
This is a unique opportunity to find new mechanisms to implement what we know
(for the politicians), for the scientists this means to find new and more efficient ways to overcome the taxonomic impediment and to open for a more dialogue
