Boating in Ankobohobo, or The Importance of Bird Areas

Many of Earth’s plant and animal species are at imminent risk of extinction. But with the resources necessary to conserve them so sorely limited, where should efforts be focused? The term “ecological triage” has been coined for such decision-making, after the system invented by French army medics to sort patients by the urgency of their need. This borrowing of metaphor from the Napoleonic and World Wars is not accidental: in envisaging the damage done to nature by humanity, you are to think of cannonballs and scorched earth and mustard gas.

“Ecological triage” can focus attention onto the regions that hold a disproportionately large amount of diversity. Such “biodiversity hotspots” have become key to global conservation, from the Caribbean to Wallacea to New Zealand. But one country stands out as among the “hottest” of hotspots: the great island of Madagascar. I’ve written for EcoEvo before about the field season I spent there, which has just resulted in a new paper published in Scopus: Journal of East African Ornithology. The paper presents findings from a series of boat surveys in the threatened and irreplaceable Ankobohobo Wetland, home to some of the world’s rarest birds.

Comparing the biodiversity and network ecology of restored and natural mangrove forests in the Wallacea Region.

Habitat loss is the primary threat to most species, as humans convert ever more areas of the globe to intensive land uses for our purposes. While some of this is unavoidable, the unsustainable level of global habitat loss has caused great damage to biodiversity, the fight against climate change, and the local economy and culture of vulnerable communities in the poorest parts of the world. It is increasingly clear that slowing habitat loss will be not be enough to repair this damage, we must restore/rehabilitate lost and damaged habitat. This process is already happening in many areas where human use is no longer economical, such as abandoned mines, upland farms and elsewhere. However restoring an ecosystem is not a simple process, many of these projects fail, and the reasons for this are not always clear. There are no agreed standards for measuring the success of habitat restoration. However in the Newcastle University Network Ecology Group we believe that ecological networks may hold the key to monitoring and directing restoration efforts. As part of the CoReNat consortium we are seeking to use ecological networks to assess the success of mangrove forest restoration projects in remote Northern Sulawesi, Indonesia.
