Greenpeace have published an interesting take on our recent paper on conserving intact peatlands here.
In an article published this month in the journal Conservation Biology, Katy Roucoux and co-authors identify and map threats to the recently-described intact peatlands of the Pastaza-Marañón Foreland Basin (PMFB) in north-east Peru. We highlight the need to protect these peatlands to avoid future degradation, and identify several key pathways for conservation.
In our study area the main threat to peatlands appears to be the expansion of commercial agriculture linked to the development of new transport infrastructure, which makes it easier for companies to access remote areas. Although some of the peatlands in the PMFB were found to fall within existing legally protected areas such as national parks, this protection is patchy, weak and not focused on protecting the most carbon-rich areas.
The article points out the considerable opportunities for conserving carbon stocks while at the same time addressing social and economic development goals in the region. The UN Green Climate Fund project in Datem del Marañón is a good example of the potential for peatlands to attract substantial amounts of money that can be used for sustainable development.
The paper’s authors are based in the School of Geography and Sustainable Development at the University of St Andrews (Roucoux, Lawson), the University of Leeds (Baker), University of Edinburgh (Mitchard), University of Reading (Kelly), Instituto de Investigacion de la Amazonía Peruana (del Castillo Torres, Honorio Coronado), Carnegie Institution for Science, Washington DC (Draper), Arizona State University (Lahteenoja), George Mason University (Gilmore), and the Field Museum, Chicago (Vriesendorp).

A new paper led by Greta Dargie and co-authored by Ian Lawson in Nature reports the existence of 145,000 km2 of peatlands in the Cuvette Centrale of the Congo Basin. We estimate carbon storage at around 31.4 Gt C. This discovery increases the best estimate of carbon storage in tropical peatlands by about 30%.
Ian Lawson has contributed to a blog post for the Journal of Applied Ecology on the impact of the ongoing destruction of Indonesia peatlands on the research community. With SE Asian peatlands rapidly diminishing, the importance of Amazonian and African peatlands as records of tropical environmental and ecological change is heightened. You can read the post here.
The floristic composition of the seasonally flooded and peat swamp forests of the Peruvian Amazon is poorly known in comparison to many other vegetation types in the region. But this lack of knowledge is not really due to a lack of fieldwork – there have been many environmental impact assessments related to the oil industry that incorporate floristic work as well as assorted inventories by different organisations. The problem is that these data remain hidden from public view and therefore knowledge does not accumulate and advance. This is the reason that this new publication by Euridice Honorio and colleagues at the Instituto de Investigaciones de la Amazonia Peruana is important: it provides open-access, baseline data on the structure and composition of Peruvian wetland forests. The availability of this information will help us to learn more about spatial variation in the composition of these ecosystems, as well as evaluate how they change over time.
Lawson et al. “Improving estimates of carbon storage and flux in tropical peatlands” is now online at http://link.springer.com/article/10.1007/s11273-014-9402-2/fulltext.html. The paper was developed by members of the UK Tropical Peatlands Working Group and reflects the group’s ambition to work more closely together, using comparable research methods, in order to improve our understanding of carbon stocks and fluxes in the tropics.
Lawson et al. “The geochemistry of Amazonian peats” is available at http://link.springer.com/article/10.1007/s13157-014-0552-z. This paper discusses new and existing geochemical data from Quistococha, Peru, and attempts to build a framework for interpreting peat chemistry. This is an important tool for understanding the processes of peat accumulation and decay, and ecosystem functioning.
A new paper by Ed Mitchard and others, using forest census plot data generated under our first NERC project, has been published in Global Ecology and Biogeography (Katy Roucoux is a co-author). You can find the paper here.
A new paper by Graeme Swindles et al. on the ecology of testate amoebae has appeared in Microbial Ecology. Co-authors include Freddie Draper, Katy Roucoux and Tim Baker. The work grew out of Graeme and Katy’s Royal Society grant. You can find the paper here.
The article, Peatlands in the Western Amazon by Tom Kelly and Freddie Draper has just appeared in NERC’s in-house scientific showcase magazine. It puts Tom and Freddie’s work on Amazonian peatlands into context. You can view it online here.
