A recently published review paper in Nature draws attention to the dangers of globalisation and international trade which facilitate spreading of fungal diseases. The authors collected data from all over the world and showed that fungal infections had increased, caused extinction of several species and even contributed to climate change in the last few decades. They claim that immediate action is needed to prevent devastating impacts of the spreading of fungal diseases mainly by more research and better implementation of science into policy and practice.

The scientists looked at the problem holistically and pointed out some unusual links. They state for example that fungal diseases can contribute to climate change through killing or damaging trees that otherwise would have absorbed significant amount of CO2. They also highlight that biodiversity loss is accelerated by fungal pathogens. Due to small population effects and decreased ecosystem diversity, a fungal disease can wipe out entire species as it is seen in the case of amphibians. In case of animal species, fungal infections already account for 72% of infection-related extinctions which is more than viral and bacterial caused extinctions altogether.

Fungal pathogens can even facilitate invaders’ success. In the well known case of the North American signal crayfish in the UK a fungus-like disease (Crayfish Plague) helps the invader. The signal crayfish is tolerant to the infection which is lethal to the indigenous white-clawed crayfish. By spreading the disease around and wiping out the native crayfish the invader can occupy more and more habitats.

Food security is also in danger. Fungal infections of our five main food crops (rice, wheat, maize, potatoes and soybeans) are already causing serious problems and destroy a significant amount of the yield each year. Newly emerging fungal diseases can affect agriculture directly while new pathogens affecting animals can also have an indirect effect on crop production. Estimations suggest that White Nose Syndrome which decreases bat populations in North America can cause huge extra costs ($3.7 billion) to agriculture through the lack of bat control on insect pests.

The authors point out that human behaviour (international travel and trade) is the major cause of the recently recognised expansion of fungal diseases. Therefore, they call for stronger international biosecurity by strengthening international trade regulations, quarantining more rigorously and tackling illegal trade more effectively through trade control organisations. They also emphasise that integrated research on identifying, monitoring and mitigating the impacts of these diseases is much needed to get ahead of fungal epidemics.

The Environment Secretary, Caroline Spelman, today announced the creation of 12 new Nature Improvement Areas (NIA) across England. NIAs were a flagship policy contained in last year’s Natural Environment White Paper “The Natural Choice”, which set out aims to improve the quality of the natural environment across England, halt the decline in habitats and species, and strengthen the connection between people and nature. Defra launched a competition to fund an initial 12 NIAs in July 2011, judged by a panel led by Professor Sir John Lawton. 76 applications were received and 15 applicants were invited to give presentations to the panel before 12 were selected to receive Government funding. The successful partnerships will begin work in April 2012 each receiving a share of the £7.5 million fund over 2012-2015, provided by the Defra family.

At the announcement of the new wildlife havens, Mrs Spelman said: “Each of these projects has something different to offer – from the urban areas of Birmingham and the Black Country to the rivers and woods of North Devon; from marshes, coalfields and wetlands to woodland and arable chalkland and grassland. The exciting wildlife projects are the result of different organisations all working together with a common purpose – to safeguard our wildlife for generations to come”.

The 12 NIAs will be:
•Birmingham and the Black Country Living Landscape: includes urban, wetland, river and heath habitats. It will create heathland on brownfield sites and 40 hectares of new native woodland;
•Dark Peak: includes moorland and woodland in the Peak District National Park. It will restore habitats such as upland heathland and create 210 hectares of native woodland;
•Dearne Valley Green Heart: is mostly on farmland and former mining settlements with woodland and wetland. It will restore the River Don floodplain and create new wetlands and woodlands
•Greater Thames Marshes: includes agricultural marsh and urban habitats. It will create and enhance grazing marsh, salt marsh and mudflat habitats;
•Humberhead Levels: straddling Yorkshire, Lincolnshire and Nottinghamshire, it is mainly wetland, lowland and peat habitats. It will create or restore at least 1,427 hectares of wetland habitat;
•Marlborough Downs: this is predominantly a farmer-led partnership looking to restore chalk and grassland habitats and increase the numbers of farmland birds as well as creating a network of traditional clay-lined dewponds to act as wildlife havens;
•Meres and Mosses of the Marches: incorporates wetlands, peat bogs and ponds in Cheshire. It will aim to reduce diffuse pollution by working with farmers, improve peatlands and restore wildlife areas around the River Perry;
•Morecambe Bay Limestones and Wetlands: the most northerly NIA, this consists of limestone, wetland and grassland habitats. It will restore coast and freshwater wetlands and create 200 hectares of woodland, planting 10,000 native trees and develop habitat for six species;
•Nene Valley: within the River Nene regional park, this project will work with farmers to restore habitats and restore tributaries and reaches of the River Nene;
•Northern Devon: this incorporates river, woodland and grassland. The project will recreate and restore 1,000 hectares of priority habitat and restore the River Torridge so that it can support the critically endangered freshwater pearl mussel;
•South Downs Way Ahead: encompasses key chalk sites of the South Downs National Park. The NIA will restore 1,000 hectares of chalk grassland and encourage the return of the Duke of Burgundy butterfly and several species of farmland birds; and
•Wild Purbeck: is a variety of river, wetland, heath and woodland habitat as well as the largest onshore oil field in Western Europe. This NIA will introduce livestock to manage heathland , restore wetland and create or restore 15 ponds as well as creating 120 hectares of new woodland and a new seven hectare saline lagoon.

Kennedy Warne, author of “Let Them Eat Shrimp: The Tragic Disappearance of the Rainforests of the Sea”, answered a few questions, posed by The Ecologist, about the importance of mangroves, the devastation caused by shrimp farming and his experiences researching his book.

You call mangroves the “rainforests of the sea”. While most people know about rainforests, most don’t know about mangroves. Why is that and why are they important?

Kennedy Warne: Mangroves tend to be associated with mud, and most people don’t like mud. (With the possible exception of potters). They also tend to harbour mosquitoes, and very few people (apart from entomologists) like mosquitoes. So there are a couple of reasons straight off the bat why mangroves have been maligned and disrespected – or simply ignored. While terrestrial tropical rainforests aren’t exactly fun places to be, with their torpid heat, abundance of bugs, high rainfall and other challenging attributes, people still recognise their importance and endorse efforts to prevent their destruction. Why aren’t mangroves higher on the environmental priority list? I don’t know. Their contribution to the planet and to humankind is immense. As I write in the book, they serve as coastal barricades and land stabilizers; they supply nutrients to the sea and nursery grounds for marine life; and they provide homes and livelihoods for millions of people across the tropical world.

In the book you detail the devastation caused by shrimp aquaculture. How has the western taste for massive amounts of this “luxury” food at a cheap price played a role?

The problem with shrimp aquaculture is that in the industry’s pioneering years, during the 1970s and 1980s, the ideal site for a shrimp pond happened to be at about the same position on the shore that mangroves flourish: low enough to get occasional tidal flow, but high enough not to be affected by tides all the time. Because mangrove forests tended to be public lands occupied by subsistence communities, they were readily appropriated by a combination of commercial aggression and governmental compliance.

Governments in developing countries became keen backers of shrimp farming because shrimp fetched a high price in the West, and was therefore a reliable source of foreign exchange. It was relatively easy for aquaculture corporations to clear mangroves and build shrimp ponds, the land was cheap to rent and there was plenty of it, so the cost of farming shrimp was low. Probably the most odious part of the early years of shrimp farming was that when one pond was nutritionally exhausted, the company would abandon it and bulldoze some more mangroves to build a new one. So the forests gave way to ever-expanding swathes of ponds. And all the while, consumers in the West couldn’t believe their luck, that such a tasty seafood was flooding into supermarket freezers and on to restaurant menus for such a cheap price. They never made the connection between cheap shrimp and disappearing mangrove forests.

As you travelled, you say first-hand the devastation caused by shrimp aquaculture and massive coastal development. How has this impacted both the environment and the local communities?

When you read statistic of how much mangrove forest individual countires have lost – 50 per cent, 60 per cent, 70 per cent – it can be very hard to get a picture of what those coastlines would have looked like if they had been left alone. But then you go to a place like the Sundarbans, the largest tract of mangrove in the world, and it starts to dawn on you the magnitude of what has been lost. And because mangroves are among the most biologically diverse forests on earth, you also realise that many species that rely on mangroves have disappeared too. Australian writer Tim Flannery wrote a book called A Gap in Nature, and that is what mangrove clearance caused: a very large, unfillable gap in nature.

Initially, my interest was focused on the natural history of mangroves. But then I started to meet people whose lives had been disrupted – more than most, catastrophically damaged – by mangrove deforestation, and I started to turn my attention to the impact mangrove loss was having on coastal communities. They were losing a physical resource, of course – source of timber, thatch, medicine, food – but they were also losing a defining part of their identity as forest dwellers. It would be like living next to a river and waking up one morning and finding the river was gone. They plight affected me deeply.

A healthy natural environment is the foundation of a sustainable future with prospering communities. In the UK and elsewhere, pioneering projects are exploring new ways of managing land and sea environments and the benefits people derive from them. In particular, they are reflecting an ‘ecosystems approach’: a holistic and inclusive approach to promoting the sustainable use of natural resources and taking better account of the values people hold for the environment. A new network has been sponsored by Defra with the aim of sharing experience from projects taking an ecosystems approach. Entitled the Ecosystems Knowledge Network, it will stimulate knowledge exchange and practical learning across the country. It will assist organisations and groups to understand how an ecosystems approach can help build sustainable communities. The Natural Capital Initiative, one of the Society of Biology’s Special Interest Groups, is developing the network in an independent partnership involving the NERC Centre for Ecology & Hydrology, Fabis Consulting, the University of Exeter (Centre for Rural Policy Research) and Countryscape.

The Ecosystems Knowledge Network is free to join and open to anyone with an interest in an ecosystems approach.

A staggering 1060 new species have been discovered over the past ten years on the pacific island of New Guinea according to a new report by WWF. Around 260 new species of vertebrate, 580 species of invertebrates and 220 new species of plants were discovered during the course of the study which was carried out between 1998 and 2008. The report titled ‘Final Frontier: Newly discovered species of New Guinea (1998 – 2008)’ forms part of WWFs 50th anniversary celebrations drawing attention to the loss of biodiversity.

Approximately two species were discovered per week throughout the study. Many new species of mammal were discovered including a new species of dolphin, a group in which new discoveries are very rare. Many new species of birds, amphibians and insects were also discovered. The study serves as a reminder of the undiscovered diversity of earth. Dr Mark Wright, conservation science adviser at WWF, said “The world is full of fantastic and fantastical creatures, of quirky and improbable lifestyles. The more we look, the more we find. But this exuberance of nature is under threat. Despite the best efforts of groups like WWF, it is clear that we will not save all we would like to.”

The island of New Guinea has an area of only 0.5% of the earth’s landmass but it has been estimated that it contains around 6 to 8% of global species, and remains relatively understudied despite this fact. The country also has extraordinarily high levels of endemic species. However the forest ecosystems of New Guinea are under threat from deforestation cause by rapid development and conversion of land to agriculture, particularly for the production of palm oil. 99 of New Guinea’s vertebrate species are on the IUCN red list of threatened species. It has been predicted that forest cover could be reduced to just 50% of its original area by over the next 10 years. Mangroves and coral reefs are also at risk from development in costal regions.

It is hoped that Reducing Emissions from Deforestation and Degradation and certification of sustainable palm oil through the Roundtable on Sustainable palm oil could provide a solution to some of the problems both people and nature are facing in the country.
