Getting the knowledge: the top 25 easy to forage wild foods

Clare Cremona and children - ready to forage — Clare Cremona and children – ready to forage

Foraging for wild food is a world away from the trolley-push through the supermarket.

Those brightly-lit aisles barely cut it when you imagine gathering wild garlic in springtime, blackberries from late summer hedgerows, or sweet chestnuts as the tired old year begins to cool.

Clare Cremona wants to remind us how easy foraging for wild food can be, and it’s perfectly possible to start at home. “You would be surprised what is coming up on a bare patch of earth in your back garden,” she says.

And as an unusually mild winter slowly gives way to spring, she adds: “Right now there is actually quite a lot about. I think everything is coming out quite early, like pennywort, that is very good in a salad.”

Pennywort – the distinctive round leaves at their best and juiciest before flowers appear, usually in May – is just one of the wild foods she has chosen in the most recent of the Field Studies Council’s handy fold-out charts.

Guide to foraging: top 25 edible plants, written by Cremona, with illustrations by Lizzie Harper, highlights some of the easier wild foods to forage for, chosen to span most of the year.

“I agonised over the 25, that was the hardest thing,” she says. “Twenty-five is not very many, that took longer than actually writing it, deciding what to leave out.”

Among those that made the cut are common sorrel, one of the earliest green plants to appear in spring; jack-by-the-hedge, another harbinger of spring, which can be used to make a slightly garlicky sauce for lamb; wood sorrel, a woodland plant, once recommended by John Evelyn as suitable for the kitchen garden; fat hen, a very old food plant, its remains have been found at Neolithic settlements throughout Europe; and wild garlic, a good addition to salads and soups.

There are hints on when and where to look for each plant, identification notes, and suggested uses.

Several of the well known favourites that need no introduction are there, such as blackberry. As is the customary health warning – never eat any wild food unless you are absolutely sure you have identified it correctly.

Cremona includes a few poisonous plants that could be confused with the edible ones, such as hemlock water dropwort, extremely toxic and probably responsible for more fatalities than any other foraged food, and dog’s mercury, highly poisonous, common in woodlands, and easy to inadvertently pick with other foraged plants.

There is a conservation issue too. She advises only picking what you need, never uprooting a wild plant (an offence without the landowner’s permission under the Wildlife and Countryside Act, 1981), and never pick a protected species, such as cowslip, even if you’ve found an old recipe book with the most tempting of recipes.

Cremona, a Forest School and Wildlife Watch leader for the Field Studies Council and Devon Wildlife Trust, says: “Generally people have a go and test something, people generally don’t strip the land of everything.

“For me it is far more important people know what they are seeing, if they don’t we are not going to look after them. And we are losing the knowledge of what you can and what you cannot eat.”

Which brings us neatly to cooking. Cremona makes her first nettle soup of the year at Easter time – it has become a family tradition – and includes a recipe for nettle soup here, and some others, including a mouth-watering wild garlic pesto.

A seasonal tradition in parts of the north of England is to make bistort pudding – sometimes called Easter-ledge pudding, dock pudding, passion pudding, or herb pudding – where foraged bistort leaves are cooked with onions, oats, butter and eggs, although recipes vary from place to place and sometimes other hedgerow leaves go into the mix.

The resulting partly-foraged and wholly distinctive savoury pudding is served as a side dish with lamb at Easter, or with bacon and eggs at other times. Competitions are held to find the best tasting, including the annual World Dock Pudding Championships, at Mytholmroyd, in the West Riding.

So perhaps this Easter is the time to have a go at foraging for wild food?

How bird atlases swept the world… with a little help from their friends

The bird atlas movement that has swept the world in the last 40 years is surely one of the great recent achievements of citizen science.

More than 400 have been published since the 1970s and it is possible more people have been involved as volunteers than in any other form of biological data collection.

But it was not birders but botanists who pioneered the biological atlas, with the now familiar grid-based dot-maps. The Botanical Society of Britain and Ireland’s Atlas of the British flora was a revelation when it appeared in 1962; half-a-century later American ornithologist Walter Ellison would describe it as the “great-grandfather of the hundreds of natural history grid-based atlases that were to follow in the next few decades as the atlas movement swept over the face of the Earth”.

1962 Atlas of the British flora - the great-grandfather of all natural history atlases — 1962 Atlas – the great-grandfather of the natural history atlas

The story is nicely told in C.D. Preston’s paper Following the BSBI’s lead: the influence of the Atlas of the British flora, 1962-2012. Planning had begun in 1950 and from the start it was intended to be a scientific exercise. The atlas in fact had little impact on science, which had to wait until computers that could analyse the amount of data atlases generate became widely available, but it did have an immediate impact on conservation – leading directly to the first British Red Data Book.

Speaking at the atlas’ launch, Max Nicholson, then head of the Nature Conservancy, described it as a great leap forward. And – we can imagine the great Twentieth Century conservationist had his tongue firmly in his cheek – suggested the ornithologists had been put to shame by the botanists.

Tony Norris, another of Britain’s conservation greats, responded when he and members of the West Midland Bird Club produced the Atlas of the Breeding Birds in the West Midlands in 1970.

The first grid-based bird atlas, modelled on the format pioneered by the botanists, covered the English counties of Staffordshire, Warwickshire and Worcestershire, and inspired the Atlas of Breeding Birds in Britain and Ireland, organised by the British Trust for Ornithology (BTO) and the Irish Wildbird Conservancy, published in 1976.

The 1976 bird atlas was followed by The Atlas of Wintering Birds in Britain and Ireland (1986), The New Atlas of Breeding Birds in Britain and Ireland (1994), and, bringing things right up to date, the Bird Atlas 2007-11: The Breeding and Wintering Birds of Britain and Ireland (2013). The fieldwork led to any number of county and regional atlases to various parts of Britain and Ireland – a recent post on the Devon Bird Atlas 2007-2013 prompted this look at bird atlases.

Dawn Balmer, the BTO’s head of surveys, guesses at least 60,000 volunteers have contributed in Britain and Ireland alone over the last 40 years, 40,000 on the most recent atlas. Some take holidays in remote places in order to fill gaps, some make expedition-like trips to remote islands, some embark on marathon mountain bike journeys to record birds in inaccessible parts of the Scottish Highlands.

She said: “The atlas only gets finished because people do amazing things. Every time there is a new atlas you are engaging people in citizen science… it is quite addictive, people become atlas addicts.”

By the turn of the 21st Century there were also British atlases to butterflies, moths, bryophytes, reptiles and amphibians, spiders, dragonflies, molluscs, leeches and ticks. Freshwater fish followed soon after, and after that fleas, the latter the product of a 50-year labour by schoolteacher and wartime Spitfire pilot Bob George.

All stemmed from the Atlas of the British flora, which perceptive contemporary reviewers recognised had a significance beyond the British Isles.

Grid-based dot-maps were promoted by the European Ornithological Atlas Committee, formed in 1971 – the idea of using grid squares, for many years a solely military pre-occupation, had originally come from the Netherlands.

Bird atlases for France and Denmark appeared in 1976. The first American bird atlas, to Vermont, was published in 1985; by 1990 all the Atlantic coastal states from Maine to Virginia had completed fieldwork for bird atlases.

At the last count there were more than 400 national or regional bird atlases from nearly 50 countries, the majority in Europe and North America. There were fewer covering Africa and the Pacific, where all but one come from Australia, and only a handful from Asia, the Middle East and South America.

The original Atlas of the British flora contained another gift: it included pre-1930 records – not as far away in time then as it appears to be now – of uncommon species as open circles and contemporary records as black dots, making it immediately clear many species were in decline.

A standout feature of the 1994 New Atlas of Breeding Birds in Britain and Ireland was a huge reduction in the breeding range of farmland birds since fieldwork for the earlier atlases had been done. The 2013 atlas revealed upland birds and wading birds – according to Balmer the extent of the latter’s problems came as a particular shock – were under far more pressure than previously recognised.

“It is about the bigger picture and you only get that from having these large scale surveys periodically,” Balmer said. “It really helps you identify species which are showing the greatest change over time and it can highlight groups that are real conservation challenges.”

Doomsday for Devon’s birds?

My Atlas of Breeding Birds in Devon has a pale blue cover, a black-and-white picture of a stonechat on the front, and a price tag of £1.50. It is more than 40 years old.

The atlas, based on fieldwork from five breeding seasons, spanning 1968 to 1972, was described, somewhat inevitably, as an ‘ornithological Domesday Book’, from which changes in the status of the county’s breeding birds could be measured.

So how does the data, published in 1974, measure up to the new Devon Bird Atlas, published this year?

Devon Bird Atlas 2007-2013 — … This year’s model

Cuckoo and starling were recorded everywhere in the old atlas, yellowhammer everywhere except Lundy. All three are now missing from large parts of the county.

The skylark was abundant throughout Devon then. Today it is scarce or absent from large areas, mainly farmland.

The skylark’s modern strongholds are Dartmoor and Exmoor and the new atlas says: “If present trends continue… the glorious song-flight will become less and less familiar in intensively farmed areas.”

The plight of the lapwing is even more pronounced. In the old atlas it was a widely distributed breeding species, despite a decline that had been noted since the 1930s; the new atlas records lapwing breeding in only three places, two of them at the RSPB’s Exe estuary reserves, the other on the southern fringe of Dartmoor.

Grey partridge was recorded breeding almost everywhere in the old atlas; now it is confirmed in only two places.

Dr Humphrey Sitters edited the old atlas, and in the preface to the new one says more agri-environment schemes are needed, but will only be put into effect if people who know what is going on “present the data we have collected and batter the politicians and bureaucrats into submission.

“Therefore, ultimately, if we lose our breeding birds it is as much our fault as everyone else involved.”

Species whose numbers have increased include siskin, Dartford warbler, Cetti’s warbler and great crested grebe.

Cetti’s warbler was not in the old atlas, the first British breeding record is from Kent in 1973 – it may now be present at all suitable sites in Devon.

There was little evidence great crested grebe bred in Devon in the late 1960s and early 1970s. Numbers have since expanded, although it is doubtful more than 15 pairs successfully bred between 2007 and 2013, the years when data for the new atlas was collected.

The old atlas does not map where peregrine was breeding. During the fieldwork years only one or two pairs managed to rear young and the bird’s future, then blighted by pesticides and egg collectors, was too uncertain to risk identifying nests.

Today it is recorded as ‘possible, probable or confirmed’ almost everywhere, although in small numbers. Persecution is still with us, however, and the new atlas again tries to mask the actual nesting sites.

The sorriest story is possibly the curlew’s. It was breeding in more than half of Devon in the old atlas, although in small numbers – curlew had still not recovered from the historically cold winter of 1962/63, a trait then shared by many other species. Now breeding pairs are down to single figures, and the new atlas says the “future of the curlew as a breeding species in Devon looks bleak”.

The great landscape historian and great Devonian W.G. Hoskins described a Blackdown Hills parish, in the east of the county, as “a country of deep, winding lanes running from one ancient farmstead to another, haunted by buzzards in the valleys and by curlews on the heaths above, and full of flowers”.

The buzzards are still there but will we again be able to hear the curlew?

The old atlas grew from the BTO/Irish Wildbird Conservancy Atlas Project 1968-72, the new Devon Bird Atlas from the BTO’s Bird Atlas project 2007-11, which resulted in Bird Atlas 2007-11: The Breeding and Wintering Birds of Britain and Ireland. A large number of other regional and county bird atlases are also available and NHBS has prepared a list showing upcoming titles.

Andrew Branson: the voice at the pulsating heart of the British wildlife movement

Andrew Branson talks to NHBS about how the UK’s biodiversity fared during his British Wildlife magazine years…

You don’t expect Andrew Branson to begin a review of how the UK’s wildlife has fared in the last quarter-century by quoting Margaret Thatcher.

Responding to emerging worldwide concern about climate change in 1990, the then Prime Minister said that as well as needing cooperation and imagination to tackle the threat, ‘We shall need statesmanship of a rare order’.

“Sadly, that is just what we don’t have,” Branson says, tweaking the message to embrace the natural world as a whole.

The previous year Branson had founded the magazine British Wildlife, described by one writer as the ‘pulsating heart of the British wildlife movement’.

The magazine, along with British Wildlife Publishing books, made Branson, according to a 2014 article in The Independent, the thinking conservationist’s candidate to rank alongside Sir David Attenborough as the person in Britain who has done most for the natural world in the last 25 years.

Many of the big issues of the late-1980s, including planting conifers on peat bogs, grubbing-up hedgerows, and river pollution, to name just three, were high on the agenda of the Government’s own conservation bodies.

But those organisations are shadows of their former selves and are unlikely to have the same influence today, Branson said. They have been cut and restructured to such an extent that they can no longer speak to Government with a strong or independent voice and are now more about delivery and process.

During the same period membership of conservation NGOs, such as the Wildlife Trusts and RSPB, has mushroomed, although none has the same statutory clout as the Government bodies.

For Branson, the rise of the NGOs is one of the period’s success stories. They are better informed than they were, he said, and better at applying scientific research on the ground. Indeed, he makes special mention of the scientists, who have done some “fantastic work on species and habitats”.

Branson uses the bittern as an example, where over the last quarter of a century numbers of ‘booming males’ have risen from around 20 to more than 150 in 2015.

“That is a powerful example of conservation action for a particular species. They have put in the research, put in the ground work, and come up with a result.”

The flip-side is that beyond protected sites, wildlife is in trouble. According to the 2013 State of Nature report, around 60 per cent of species have declined.

Branson says: “The statistic that really hits you is that the UK has lost 44 million breeding birds since England last won the World Cup in 1966, and these losses are down to the general countryside being more intensively farmed, to loss of habitat, and the effects of aerial and water-borne pollution.”

On his local riverside walk in 1989 he would regularly see turtle doves and water voles. Now they are gone. The turtle dove is at risk of becoming extinct in Britain.

“These changes can be subtle. People see cattle grazing in a grassy field and think ‘that is fine’. But a while ago that same field may have held 50 or 60 species of plant, whereas now it may have only four or five.”

Generally, the public’s understanding of the problems is now greater than in 1989 but politicians need to wake up, he said. The current government, in particular, appears to have little clue when it comes to wildlife and the countryside. Time for some real ‘statesmanship’ he muses.

Branson sold British Wildlife Publishing two years ago, but is still busy working with wildlife groups in his home county of Dorset.

Trees in Winter: another way of seeing

Winter woodland has a bare, skeletal charm all of its own, and a walk in the woods is a good time to try to put names to those familiar trees.

Suddenly leafless but not as anonymous as we sometimes think, with a little practice it is surprisingly easy to begin to place those barren winter twigs.

Here is a quick, and by no means definitive, guide to identifying six of the UK’s more common deciduous trees in winter, chosen at random on a midwinter ramble in my local woods.

Oak (below): A rugged twig with fat, oval orange-brown alternate buds, and a characteristic cluster of buds at the tip. The twig of the sessile oak is less rugged than pedunculate oak, but be careful the two species often hybridise and it can be tricky to tell the difference.

Ash: A twig that looks as if it means business, with black buds in opposite pairs and an unmistakable, fat terminal bud covered in black scales.

Beech: A slender, rather delicate twig with long, alternate and markedly pointed brown buds. Hornbeam is very similar but the buds hug the twig rather than point outwards, and the twig is noticeably more zigzagged.

Hazel: The twig is downy all over – although you may need a hand lens to see this clearly – with alternate, pale green to reddish-brown, smallish buds. Catkins are not at the end of the twig, unlike in birch species.

Field maple: Hairy twig and buds – again a hand lens is useful – with tiny reddish-brown buds, always in opposite pairs. The terminal bud often has smaller buds on either side, sometimes appearing to be a triple end bud.

Sycamore: Another sturdy twig, with plump pale green buds in opposite pairs. The large green bud scales on the terminal bud are easy to see.

I use an elderly copy of the Forestry Commission’s Know Your Broadleaves for Christine Darter’s fabulous drawings of winter twigs; David Streeter and Rosamond Richardson’s similarly dated Discovering Hedgerows has a useful key.

The stand out work is Dominic Price and Leif Bersweden’s Winter Trees: A Photographic Guide to Common Trees and Shrubs one of the Field Studies Council’s AIDGAP Guides, which covers 36 of the common broadleaved tree and shrub species likely to be found in the UK, as well as a few rarer ones. With pictures of bark as well as twigs, and notes on habitat, winter tree-ID suddenly seems much easier. Author royalties from the book go to the Species Recovery Trust.

For those wanting a guide to even more tree species, Bernd Schulz’s Identification of Trees and Shrubs in Winter Using Buds and Twigs covers over 700 species. Containing more than 1,400 colour illustrations, as well as detailed descriptions and identification keys, this guide is comprehensive and easy to use.
