Serengeti road halt for wildlife

24 June 2011 Last updated at 13:07 GMT Richard Black By Richard Black Environment correspondent, BBC News Sunset in the Serengeti The Serengeti is a key destination for tourists in Tanzania Controversial plans to build a tarmac road across the Serengeti National Park have been scrapped after warnings that it could devastate wildlife.

The Tanzanian government planned a two-lane highway across the park to connect Lake Victoria with coastal ports.

But studies showed it could seriously affect animals such as wildebeest and zebra, whose migration is regarded as among the wonders of the natural world.

The government confirmed the road across the park will remain gravel.

In a letter sent to the World Heritage Centre in Paris, the Department of Natural Resources and Tourism says the 50km (30-mile) section of road across the park will "continue to be managed mainly for tourism and administrative purposes, as it is now".

The government is considering an alternative route for a major trade highway that would run to the south of the park.

This would avoid areas of high conservation value, and - although a longer route - would bring the opportunities afforded by a modern transport link to more people.

Last year, a group of scientists warned that the proposed road across the park could bring the number of wildebeest in the park, estimated at about 1.3 million, down to 300,000.

Collisions between animals and traffic would be unavoidable, they said.

And with a corridor on either side of the road taken out of the hands of the park authorities and given to the highways agency, fencing would almost certainly result, blocking movement of the herds.

If wildlife were damaged, they warned, that could also affect the local economy, in which tourism plays a major role.

'Wonder of nature'

The researchers described the Serengeti as "a rare and iconic example of an ecosystem driven by a large mammal migration".

That annual north-to-south trek involves about 1.5 million animals, including wildebeest and zebra.

As the animals travel, they dump vast quantities of urine and dung across the land, fertilising plant growth, while the trampling of hooves also prevents bush from over-growing the grassland.

An impact assessment compiled for the government confirmed the expected impact on migration, adding that the decline of wildebeest and zebra would have a knock-on effect on predators such as lions and cheetahs.

These are among the animals that tourists come to see.

Scientists also warned that the road could bring invasive plant species or unfamiliar diseases into the park, a World Heritage Site.

Last year, the World Heritage Committee expressed its "utmost concern" about the "potentially irreversible damage" that the highway could bring.

Environmental campaigners have welcomed the government's decision, with the organisation Serengeti Watch saying: "A battle has been won".

However, they warned that the region faces a number of other threats, including roads around the park and poaching.

A smart way to save wildlife

24 June 2011 Last updated at 02:51 By Ella Davies Reporter, BBC Nature Ladybird photographed on smart phone (ladybird image shown by Ingo Arndt / NPL) Wildlife, smartly recorded Modernity is often the enemy of conservation, as our 21st-Century lifestyles put ever greater pressure on the natural world.

But some modern inventions may also hold the key to saving species in the future.

On Friday, scientists at the Zoological Society for London (ZSL) announced the launch of a new "bat phone" - not a superhero's tool but a smartphone app that ordinary folk can use to track the movements of local bat species.

It is an example of how conservationists are harnessing the power of smartphones, the internet, online crowd sourcing and social networks to keep track of the natural world.

End Quote Wall Street Journal describing Project Noah, a modern wildlife recording tool Crucially, that involves encouraging the public to act en masse as field researchers, gathering data.

But can amateur natural historians, and the evidence they collect, really help save wildlife?

Rise of the net

Citizen science in not a modern phenomenon. For more than a hundred years, enthusiastic volunteers have assisted with the widespread recording of flora and fauna.

Traditionally, fieldwork performed by volunteers was overseen by a qualified expert or investigating scientist. Volunteers were friends, family, society members, passionate enthusiasts and those living and working in the survey area.

However, the internet has allowed projects to catch the public's attention as never before.

For example, the new iBat app has been developed for a global bat monitoring programme covering at least 16 countries.

Produced by an international team of experts, including ZSL and the Bat Conservation Trust, the app allows volunteers to detect and record more than 900 species of bat with the help of an ultrasonic microphone.

The rich soundscapes recorded are uploaded to a website that identifies each of the calls to build an accurate picture of bat populations, essential for future conservation efforts.

The BBC has also helped break new ground in using online mass participation surveys to record wildlife.

Springwatch and Autumnwatch, programmes with more than 2.5 million viewers, promote studies of the seasons, in particular the Woodland Trust's online survey Nature's Calendar, which has more than 50,000 participants.

For this survey participants are encouraged to submit the dates and locations of specific seasonal events, including the first bluebell blooms and the first autumn colours.

It is the largest of its kind in the UK. And since the data is used to track the arrival of the seasons, it has the potential to add to our knowledge of the local effects of climate change.

In 2009, Springwatch asked its viewers if they could help document the decline of the cuckoo.

An impassioned response saw 12,000 people inundate the programme's blog with the locations where they had heard the bird.

The British Trust for Ornithology (BTO) helped process the audience's response, which varied from detailed co-ordinates to anecdotal approximations, while comments on the blog were used to create a map of cuckoo distribution that resembled that produced by the BTO's own Bird Atlas survey.

But public surveys of this kind have pros and cons.

Cuckoo distribution map (c) BTO The Springwatch cuckoo map: can blog comments constitute accurate data?

Online wildlife surveys can actually sever direct links between scientists and citizens. Anyone can engage with an internet-based project, so scientists that organise them must take a very hands-off approach, instructing volunteers using picture based guides or lists of FAQs.

Though more convenient, this runs the risk of unreliable data being gathered, as individuals interpret their findings differently.

The Springwatch cuckoo map, for example, did not meet the exacting standards of a truly scientific survey, says Graham Appleton, the BTO's director of communications.

"Sadly, we were unable to add the records to our database because we had no way to check the validity of each of the original reports [with] no clear chain back to the person reporting a cuckoo and because the geographical placement of some of the dots was not reliable," Mr Appleton tells BBC Nature.

In their own surveys, the BTO uses a team of local expert volunteers to double check any vague or surprising records, to keep their results at a high standard.

But efforts are being made to overcome these difficulties.

Scientists increasingly pay close attention to how they pose their questions and collect their data. And the BTO and BBC worked hard to improve their data gathering before the autumn of 2009, when Autumnwatch asked viewers to help survey tawny owl numbers.

"We learned from the cuckoo survey," says Mr Appleton. "This time, we collected precise information on location, using click and point mapping software, and information on the people who sent in records of hooting owls."

The data was suitable for inclusion in the Bird Atlas and, by inviting viewers to record owl hoots at night, the BTO was able to extend the coverage of its survey outside of daylight hours.

"We were pleased to fill in a number of the gaps in the grid of 10km squares that cover the whole of the UK," Mr Appleton tells the BBC.

Virtual collections

Getting the public to collect hard evidence about a species' location or movement can vastly improve the information gleaned by scientists.

In Kenya, the Mara Predator Project invites tourists to submit lion sightings, to help monitor populations on selected reserves.

The project's website provides an ID guide to help interpret holiday snaps, so that researchers can track prides and individuals.

End Quote Yasser Ansari Founder, Project Noah Meanwhile Project Noah is a global study that encourages nature lovers to document the wildlife they encounter, using a purpose built phone app and web community.

Launched early last year, the developers behind the project aim to reconnect people with nature, while the Wall Street Journal commented that smartphones were the "butterfly nets of the 21st Century" when it described the project.

"We've helped people learn about organisms they never knew existed and we've brought awareness to important work and research," says the project's founder Yasser Ansari.

"We've had visitors from 192 countries, nearly 94% of the world, and have photo submissions from all seven continents."

In addition to the virtual "collection" of species, Project Noah encourages citizen science by linking up with existing surveys including the International Spider Survey and the Global Coral Reef Monitoring Network.

By submitting time-stamped, geographically tagged photographs to the site, users can contribute data to official monitoring programmes and studies.

However, when it comes to measuring whether the community is genuinely improving research, it is still early days, says Mr Ansari.

"We launched our current platform just a few months ago and have received a phenomenal response, but no research breakthroughs have been made yet," he says.

"I do think that breakthroughs can be made, but only time will tell."

Bridging the gap

However, citizen science has already been responsible for some notable natural history discoveries.

In the UK, iSpot by the Open University is a natural history social network that aims to help amateurs identify anything and everything from the natural world by putting them in touch directly with experts.

iSpot did not set out to be a source of research data, but in fact we have been so successful that we have generated useful scientific data as well as introducing people to natural history”

End Quote Professor Jonathan Silvertown iSpot Project Leader Not initially designed to produce scientific results, the project has already identified two species previously unrecorded in the UK: a bee-fly (Systoechus ctenopterus) and euonymus leaf notcher moth (Pryeria sinica).

"It's important to say that iSpot did not set out to be a source of research data, but in fact we have been so successful that we have generated useful scientific data as well as introducing people to natural history," says Jonathan Silvertown, iSpot project leader and professor of ecology at The Open University.

"A dataset for shieldbugs observed on iSpot was recently validated by the expert who runs the national recording scheme for this group and it has now gone into the records of the National Biodiversity Network."

"We are sure that this is just the first of many datasets that will do this," he adds.

Professor Silvertown says organisations' hesitancy to embrace citizen research is understandable, because of the issues of interpretation and accuracy.

But he argues that involving the public in research is hugely valuable, particularly when that research is publicly funded.

Meanwhile Mr Ansari believes projects such as his own could be inspirational for the next generation of scientists.

"Think of our effort as training amateurs to become better nature observers... All scientists start off as amateurs," he says.

Wildlife warning over EU funding

21 June 2011 Last updated at 13:08 GMT Farmland in East Sussex Farmers can receive thousands of pounds for initiatives boosting wildlife on their land More than ?400m worth of funding from Europe to promote wildlife on farmland in the UK could be about to be stopped, conservationists have warned.

The RSPB fears the money provided through the Common Agricultural Policy will be the victim of EU spending cuts.

The charity said such a move would be "savage" and could threaten the recovery of many wildlife species.

The government said the initiative was good value and any cuts should target farm subsidies for food production.

Under the terms of the Common Agricultural Policy, farmers are paid subsidies for the food they produce. Officially these direct payments - the lion's share of the CAP - are known as "Pillar One".

Many farmers across Europe also receive payments which can amount to thousands of pounds for developing initiatives on their land aimed at promoting biodiversity and wildlife. These rural development payments are called "Pillar Two".

Our countryside has faced many threats, but this would be really savage. We're staggered.”

End Quote Martin Harper RSPB conservation director 'Ultimate extinction' The RSPB said it understood the European Union was considering scrapping the Pillar Two payments to save money.

RSPB conservation director Martin Harper said: "Our countryside has faced many threats, but this would be really savage. We're staggered.

"Rewarding farmers for protecting threatened wildlife has provided a lifeline to many sensitive species, which would otherwise have ebbed away.

"If the EU continues with this plan there is no doubt that wildlife will suffer, with the possible ultimate UK extinction of some threatened species including the turtle dove and cirl bunting."

The RSPB, the UK's largest conservation group, said hedges, stone walls and waterways could also be affected.

The UK's Department for Environment, Food and Rural Affairs (Defra) echoed the RSPB's concerns.

A Defra spokesperson said the CAP budget "needs to decrease very substantially - but cuts should be focused on Pillar One. We're concerned by rumours that Pillar Two may be disproportionately in the firing line.

"Pillar Two is better value for money, contributing to economic growth, supporting the environment and agricultural competitiveness, and should have a larger share of a smaller CAP budget."

Proposals for the EU's new budget will be announced on 29 June.

'Wildlife to work' survey begins

9 June 2011 Last updated at 14:15 GMT By Mark Kinver Science and environment reporter, BBC News Peregrine falcon (Image: AP) In recent years, peregrine falcons have set up homes in an increasing number of towns and cities Workers are being encouraged to make a note of the wildlife they encounter during their daily commutes.

Described as the first nationwide survey of its kind, BBC Wildlife Magazine is asking people to send in details of birds and animals they see.

It is also keen to receive details or photographs of people's memorable wildlife encounters.

The magazine plans to publish the results from the survey in a special report later in the year.

"It is not a comprehensive, scientific survey, but hopefully it will cast a light and help illuminate where our wildlife is and how it exists," explained James Fair, the magazine's environment editor.

He added that it was not necessary for people to have a detailed knowledge of birds and animals in order to take part.

"If someone knows that the bird they have seen is a juvenile, male great spotted woodpecker, then that's great as well," he told BBC News.

"But if someone else just sees a woodpecker in a tree next to the pub, that is great too."

"What we really want is to encourage people who do not usually record or talk about their wildlife sightings."

'Urban birder'

People can submit their sightings by using the form in the magazine, or visiting BBC Wildlife's website or emailing the details to the editorial team.

Respondents will be asked to list the species they have seen, in what region of the UK they spotted the creatures, and what mode of transport they were using - e.g. car or train.

"We're particularly keen to hear from people in urban and suburban areas to find out what unexpected wildlife is living in and around our towns and city streets," Mr Fair added.

"Don't worry if you're mostly seeing pigeons, squirrels or other common species though - wherever you go, whatever you spot, we want to hear from you."

Writing in the magazine, self-declared "urban birder" David Lindo encouraged people to look upwards during their trip to work.

"One winter's morning a few years ago, I detoured to see about 150 waxwings feeding on rowan berries," he recalled.

"Masses of commuters marched past on their way to work, totally oblivious to these gorgeous Scandinavian visitors."

Mr Fair said that he planned to publish the results from the survey later in the year.

"We are going to try and tease out things from the information we receive, such as the most common species," he suggested.

He added that he hoped the survey would become an annual fixture to help build up a picture of how the ecological landscape changes over the years.
