Woodland Watch – Week 17 – 10/07/2013

This week, I thought we would have a bit of a change…Its summer, the sun is out, the skies are blue and the woodlands and hedgerows are full of wild foods. It’s so easy in the modern world to walk into any supermarket and pick up fruit and vegetables, but our natural environment is absolutely bursting with a wealth of wild food that the supermarket shelves cannot boast.

Last week, we looked at the elder and the battered fritters that you could make. The summer months are an odd time for foraging. The fresh burst of green salad and herb leaves have turned bitter and mature, but the wealth of autumn fungi and fruits are not yet ready to eat…So what can we eat at this time of year?

Lets go for a walk in the woods and find out.

One of my favourite wild food recipes has to be comfrey fritters. A hairy plant generally found on damp ground beside rivers and ditches and on roadside verges and waste ground, it does not immediately attract the forager. It has become an important plant for organic gardeners, providing a rich fertiliser and used as a composting aid…but what could possibly turn this hairy leaf into an appetizing snack?

Well, when in doubt, in my opinion, most foods can be improved with a bit of batter!!! I know its not exactly healthy, and believe me I’m the first to advocate healthy eating…But comfrey leaf fritters dipped in sweet chilli sauce is a must try wild food!

Ok, lets try and move towards something a little more healthy! Last week we looked at elderflower fritters, but there’s a huge array of recipes for food and drink that use these wonderful flowers. While they’re still available freely all over the hedgerows, why not try your hand at making some refreshing summer drinks?

Have you been to the supermarket recently and purchased elderflower cordial? It’s such an easy drink to make and can keep the flavour of summer alive in your kitchen all through the winter.

So, take a look at this recipe for elderflower cordial:

And when you’ve mastered this one, why not look into its alcoholic sisters. There’s a wealth of options from elderflower wines and champagnes to elderflower beer. The flowers are coming to the end of their lives this season, but if you’re quick you might still have a chance. If you’re too late, you’ve got plenty of time to plan your recipes ready for next summer.

Another plant still growing strong all over the countryside and still present all over our woodland, providing a wide range of foraging opportunities, is the nettle. Another foragers’ dream plant, nettles provide a huge array of wild food and drink opportunities. So, following on from the elderflower beverages, lets have a look at nettle beer!

Nettle Beer

Nettle Beer

Now making an appearance on supermarket shelves, nettle beer is proving a popular novelty ale, but there’s no need to buy it in the shops. Everyone can identify a nettle, they’re abundant all over our countryside, so why not make use of them?

When you collect the nettles you should only take the tops as there are many insects who benefit from the plant and you will be taking away their habitat if you take the whole nettle.

Have a look at these recipes to start making your own nettle beer:

Now, moving on to another less well known plant, lets take a look at sorrel. There are two distinct types of sorrel, they look different, require different growing conditions and are found in different locations. They share a sour, lemony flavour and both were once used much as lemons are today. Sorrel can be found from spring until autumn and the most common varieties are sheep’s sorrel and wood sorrel.

For tips on identifying sorrel, have a look at this link:

http://wildandslow.com/wp-content/uploads/2011/03/WILD_SORREL_FINAL.pdf

So, what can we do with sorrel? As with the other foraged foods we have looked at, sorrel has many, many uses. It can be used in everything from soups to salads and everything in between. Here we’re going to look at sorrel pesto, but just search around and you’ll come across a wide range of other recipes.

Look for wild sorrel among meadow grasses and flowers in spring and summer. Pick only fresh young leaves – older ones can taste bitter. Then take a look at this recipe for sorrel pesto along with a range of other sorrel recipes on this page:

You can’t possibly think about summer wild food recipes without touching on the wild strawberry. Summer is a wonderful month for sweet berries and with recipes ranging from tarts and fruit puddings to ice creams and pancakes a summer foragers recipe collection cannot possibly be complete without the wild strawberry.

Much smaller than its cultivated relatives, the wild strawberry packs a phenomenal amount of flavour into its small package.

We could go on and on with so many wild food recipes inspired from our own walks in the woods. We hope that this mini taste of wild foods helps you to get into looking around you when you go for your own walks, whether you’re in the woods, on the river banks or in the meadows. Wherever you are, the British countryside is bursting with a wealth of foods which put the supermarket shelves to shame…You just have to know where to look and what to do with the foods you find.

Happy foraging and don’t forget…If you’re not 100% sure what it is, don’t eat it until you are sure! Let us know how you get on and we’ll keep you posted on our own foraging recipes.

Join us again next week for another walk in the woods.

Woodland Watch – Week 16 – 03/07/2013

Another week in the sunshine! What a wonderful day for a walk in the woods…So lets see whats changing this week.

Crossing the little wooden bridge into the woodland copse, the ditch along the woodland boundary which was running with deep water over the winter and early spring is now completely dry.

The ditch on the boundary of the woodland copse, completely dried up

Along the banks of the ditches, there is an abundance of vegetation which has grown up since the spring. One of the most common plants along the ditch edge is Cow Parsley (Anthriscus sylvestris).

Cow Parsley growing on the banks of the ditch on the woodland boundary

Cow parsley grows in sunny to semi shaded locations, therefore it is well suited to locations such as this on the boundary of the woodland copse. It is sufficiently common and fast growing to be considered a nuisance weed and its ability to grow rapidly through rhizomes and to produce large quantities of seeds which has meant that it can be considered an invasive species. Cow parsley is beneficial for a range of wildlife, including bees as long as it does not take over and become a monoculture. As in most cases, growing as part of a varied ecosystem, cow parsley is a valuable native species.

Sticking with the theme of white summer flowers, we will move on to look at the elder. Earlier on in the year we looked at the Jews Ear fungus growing on some of the elder in the woodland, but now the focus is on the flowers. Like blackberries, Elder is one of the most commonly foraged for wild foods and it is abundant in hedgerows and verges at this time of year.

Elder is one of those really useful native species which is often undervalued. It provides good foraging for wild game such as deer and is classified as nesting habitat for a range of birds. The flowers provide nectar for pollinating insects and later in the year a wealth of elderberries will provide food for birds and small mammals. It also provides good lower level cover in a woodland habitat.

Aside from its wildlife value, elder has also been used through out history into the present day as a culinary plant, although it is worth noting that all of the green parts of the plant are poisonous, containing cyanogenic glycosides. The berries can be eaten raw when fully ripe, but are mildly poisonous in their unripe state. Elderberries are most commonly used in cooking to make jam, jelly, chutney and used to infuse alcoholic drinks.

The flower heads are commonly used to make elderflower cordial which is diluted with water before drinking. Additionally, the flowers can be used to make alcoholic drinks including elderflower wine and champagne.

One of the nicest culinary uses for elderflower that I have come across was a batterred elderflower fritter served with homemade strawberry ice cream. The flower heads were left attached to the stalk and the whole head was dipped into a batter mixture, then into hot oil to make it crisp. The finished result looks like this:

And sticking with the theme of blossoms and berries, the last time we took a look at the hawthorn it was in full blossom. Now only a few weeks later, the blossom has gone, replaced with young haws which will develop over the coming months to a deep red fruit.

The Treecreeper Arborists Guide to Looking After Your New Tree

Thank you for coming to talk to us at North Nibley Music Festival and here’s your guide to planting your new tree!

Following the expert advice you have been given in selecting your sapling, you should have a suitable species for your chosen site. Remember, trees are like children – you have to nurture them to help them grow up big and healthy.

Ok, you have your little sapling clutched firmly, and you want it to become a successful tree, so after all the work you will put into it over the next few years it will result in a nice patch of shade to relax in.

Relaxing under a tree

Relaxing under a tree

Firstly, make sure that the roots don’t dry out. We have gone to great lengths to ensure there is minimal disruption to the root system, but there is inevitably some damage to the very fine roots which do all the hard work like taking in water and dissolved nutrients in the soil. These are really important, and each time the tree is moved, more damage occurs to these roots.

At this time of year, the trees are using a fair amount of water, with moisture evaporating from the stomatal pores in the leaves which pull water up from the roots via capillary action. This means the water demand is really important. Ideally, trees should be moved over the winter, when the water demand is much lower, and the tree can cope with the shock more easily.

So in order to ensure the roots have their best chance of survival (and therefore the tree), we must give it the optimal growing conditions. This means digging a hole. It doesn’t have to be too big, as a rule of thumb you can work on around about four times the size of the root ball. You won’t have to dig deep either, as burying the roots too deep will kill or severely weaken the tree. Make sure when you settle the tree in the hole that the point where the roots start to spread out from the stem is at ground level.  Your hole should have gently sloping sides, which if your soil is clay based may become glazed by the back of the spade.This creates a barrier to the roots spreading out, so just loosen the soil all around the edge of the planting pit a little with the edge of the spade.

Digging the hole for your tree

Digging the hole for your tree

Put a bit of nice soft soil or compost in the bottom of the hole, enough to raise the tree to the correct height. While you can still see the roots, and want to use a stake (or a cane) now is the time. Push it down, making sure the roots are missed.  Now fill the rest of the hole with your nice soft soil, and give your tree a bit of a jiggle up and down, which will make sure all the little nooks and crannies are filled with soil. Firm the soil lightly as you go, until you reach the correct height. Stand up, admire your work.

Now, you can give your tree in its new home a good watering, until there is a bit of standing water on the surface of the soil. Depending on whether or not you feel like it, put a bit of mulch around the base. This both keeps the weeds down around the tree so it has less competition for nutrients, and also helps to retain moisture in the soil, so when we have our next hosepipe ban (you know, just before the flooding starts) there is a bit less watering to do. For mulch, just about anything will do. A bit of woodchip, grass cuttings, straw, bits of cardboard or even offcuts of carpet.

Now you have successfully planted your tree we hope it gives you many years of pleasure.  Remember, the best time to plant a tree is twenty years ago. The second best time is now . . .

Woodland Watch – Week 15 – 26/06/2013

Summer seems to finally be here and although it is neither as warm or as predictable as we would like, at least it is not as cold as it has been! This week my walk in the woods was overcast, but warm and I hope you will join me to have a look at what is going on this week.

The grass in the meadow approaching the wood is getting taller and taller but closer to ground level you can see lots of little purple clover flowers.

Clover growing in the hay meadow

Clover growing in the hay meadow

This red clover (Trifolium pratense) is a native, herbaceous perennial plant which can grow 20-80cm tall. The genus is so named because of the leaf structure consisting of three leaflets, known as trifoliate leaves. Clover is an interesting plant, widely grown as a fodder crop and highly valued for its nitrogen fixing capabilities which increase soil fertility.

Nitrogen fixation is the process by which nitrogen in the atmosphere is converted into ammonia. In the atmosphere nitrogen exists as a diatomic molecule (the atoms go around in pairs, like oxygen). In this inert state it does not easily react with other chemicals to form new compounds. Nitrogen fixing nodules in the clover plant frees up the nitrogen atoms from their chemical diatomic form (N2) to be used in other ways.

Before the establishment of science, when peopled looked to religion and magic for medicinal cures, red clover was already playing a part in people’s lives. To early Christians, it was a sign of the Trinity while during the Middle Ages, it was regarded as a charm against evil. A mutation resulting in the well-known four-leaf clover is considered good luck when found, even to this day.

Heading into the woodland, the first difference that was immediately apparent was how dark the wood was compared to previous weeks. The canopy has now almost completely closed over with a hazel lower canopy and an upper canopy made up of a range of other broad leaf trees including oak and horse chestnut.

The woodland was noticeably darker now the canopy has closed over

One of the lower level tree species that we haven’t yet touched on but which I have noticed on my walks is the holly (Ilex aquifolium). An evergreen shrub which most people can easily recognise it can grow 10-25m tall with sharp spiney leaves which last around 5 years. What many people don’t realise, and to the relief of tree surgeons such as ourselves, is that leaves on the upper branches of mature trees do not have spines as they are well out of the reach of grazing animals and do not require this particular defense mechanism. 

Lower leaves of a mature holly tree

Holly is dioescious which means there are male and female plants, unlike the hazel which we saw developing the male catkins and female flowers on the same trees. The sex of the plants cannot be determined until they begin flowering, usually between 4 and 12 years of age. Between October and November, the flowers on the female plants will grow into red fruit which is eaten by birds and rodents.

Interestingly in the Irish/Gaelic ogham alphabet holly is called Tinne, a word believed to have originally meant ‘fire’. From this was derived the word ‘tinder’, referring to dry, inflammable matter used for kindling fire from a spark. This association between holly and fire has been known since ancient times when charcoal made from holly wood was used by armourers to forge swords and axe heads.

The holly will remain fairly constant through the changing of the seasons, but it is a highly valuable woodland species.

Sticking with the theme of trees, another species to note is the English elm. Once a classic English tree like the English Oak, the elm all but disappeared from our countryside after Dutch Elm Disease reached Britain in 1927.

Now, these small elm saplings around the edge of the wood, although relatively common at this stage of their lives, are unlikely to reach maturity.

English Elm saplings

English Elm saplings

The current DED epidemic is caused by the fungus Ophiostoma novo-ulmi which is dispersed by various elm bark beetles within the Scolytus genus. The fungus blocks water conduction, resulting in wilting and eventual death of the foliage.

The first signs of the disease are often yellowing/browning of foliage tips as the affected branches are gradually starved of water.  When the leaves fall, the remaining twigs often turn down to form ‘shepherds crooks’ which can be valuable for disease detection in winter.

The diagram below shows how the disease progresses.

Dutch Elm Disease

Dutch Elm Disease

Although the English landscape has certainly lost the majority of its mature English elms, the Ulmus procera species has not disappeared completely from the landscape. This is because the elm bark beetles require bark to be of a certain thickness for breeding to be successful.

When an English Elm is killed by the disease, some roots remain alive and new elms regenerate from these. This means that for every mature elm killed by DED, many more are able to replace it. We may not have many large elms, but there are millions of young elms growing all over the English countryside, such as these young saplings in our wood.

That’s it for this week. Join us again next week for another walk in the woods.

Woodland Watch – Week 14 – 19/06/2013

It seems as fast as I get used to warm spring/summer weather everything turns around and its back to miserable grey again! This week wasn’t great weather for a walk in the woods, but me and the dog made it out anyway and here’s what we saw this week!

Despite the dreary looking sky and cold, blustery wind that felt more like early spring than early summer, the meadow approaching the woodland was still beautiful, covered in buttercups and a wide range of flora.

Stormier skies than in previous weeks as we approached the woodland

The buttercup family is comprised of about 2,252 species, including wildflowers and ornamentals, such as larkspur, marsh marigold and clematis. It used to be thought that the rich yellow of the buttercup made better butter from cows feeding in buttercup-rich meadows. This is a myth however, as we now know that the stem and leaf are actually toxic, especially to cattle, and the animals avoid eating it.

The meadow is full of a wide variety of flowers, herbs, grasses etc and I am the first to admit that my meadow species identification needs a lot of work, so please feel free to correct any mistakes!!! Species such as the common plantain and clover are widespread among the buttercups.

Ground level vegetation in the meadow approaching the woodland

Inside the wood, the woodland floor has changed again. The green bluebell leaves from previous weeks have turned yellow and collapsed as they come to the end of their life for this year. The stems and seed pods are still upright, bare looking without their foliage.

While these areas of the woodland look bare now that the bluebells have died back, other areas are overrun with weeds. On entering the woodland area there are large patches of young brambles which will continue to dominate the vegetation where they can through the summer months.

Although generally considered a woody week and certainly difficult to eradicate once they become established, brambles are a very useful plant to a wide range of wildlife. Hundreds of creatures use brambles at different times of the year: Insects visit the flowers for pollen and nectar, including bumblebees, honey bees, hoverflies, wasps, butterflies, moths, flies and lacewings.Spiders spin webs to catch the bounty of visiting insects. Moths such as buff arches, peach blossom and fox moths lay their eggs on bramble as it is their larval foodplant. Blackbirds, thrushes, chaffinches, starlings, robins, pheasants, foxes, mice and other small mammals eat the fruits. Robins, wrens, thrushes, blackbirds, warblers and finches will nest in bramble and small mammals use it for protection from predators.

A weed the bramble may be, but it is certainly a very valuable woodland plant as long as it is not allowed to out compete other valuable vegetation. The key to any habitat is variety.

That’s it for this week. Join us again next week for another walk in the woods.

Woodland Watch – Week 13 – 12/06/2013

Welcome to another week and another walk in the woods. I have been amazed watching this woodland week by week, seeing all the changes and this week was just as exciting. So, here we go!

One of the standard trees in this woodland that we haven’t really looked at yet is the oak. There are several oak trees around the site, both young and mature specimens. This year, with the cold start to spring it took the oak trees a while to come into leaf. As you can see now, the oaks are properly in leaf and their vibrant green leaves provide a beautiful upper canopy to a few areas of the wood.

Looking up through the oak canopy

Looking up through the oak canopy

Of all our native trees, the oak is probably one of the most commonly recognised by people. Widespread in fields, hedgerows and woodlands it is arguably one of the classic English trees. There are over 400 species of oak worldwide including trees, shrubs, deciduous and evergreen varieties and they can live up to 700 years old, outliving all other trees in the UK except the yew.

In this woodland we have the native English Oak. Male catkins appear on the tree with the leaves in April and become long, pollen-filled pendulous by May. Then the female catkins open as upright flowers which await the touch of fertilising pollen from the males. They hold the seed vessels which will become acorns, the fruit of the oak tree.

I will look out for these in the coming weeks. For now, here’s another beautiful picture of the leaves of a young oak tree, bright and vibrant with new life.

Bright young oak leaves

We already noted last week the dramatic change in the colour of the woodland floor. Only a couple of weeks ago it was covered in the vivid blue of the bluebell flowers. Last week we saw the change to green as the flowers disappeared and the leaves started to wilt.

Bluebells reproduce through propagation by seed using sexual reproduction. They are usually pollinated by insects and after fertilisation occurs, the seeds are produced and dispersed. In the woodland, now that the flowers have disappeared you can clearly see all of the seed pods still standing on the upright stalks. Right now the seeds are still green, but they will turn darker as they mature before they are ready to disperse.

Bluebell seed pods

Going back a few weeks, before the hazel leaves burst into life we looked at the male catkins and female flowers and how the hazel reproduces. Now that this has happenned and the female flowers have been fertilised, the male catkin has fulfilled its purposes and drops off, leaving the female to produce the nuts that we will see in autumn. Walking around the wood, you can see many of the used, male catkins on the woodland floor.

Male catkins drop off once they have fertilised the female flowers, leaving them to develop into nuts ready for autumn.

And sticking with the theme of reproduction, the hawthorn has also just come into flower. Later than in most years but making a beautiful sight, especially around the boundaries of the wood where this photo was taken.

Hawthorn flowers coming into bloom on the edge of the wood

These blossoms contain both male and female reproductive parts and are fertilised by passing insects. By summer the seeds will grow into small green berries which will turn dark red by autumn to attract birds who will eat the berries and propagate the seeds. We will watch the hawthorns in the woodland as they move through this cycle.

And that’s it for another weekend of woodland watch. Join us next week for another walk in the woods!

Woodland Watch – Week 12 – 05/06/2013

This week, I decided to focus on the coppice. There’s such a lot going on in the woodland at the moment now that the weather has finally warmed up, but over the last 11 weeks we have takes a lot about the “coppice woodland” and never really elaborated on what this means.

So, here we go. Lets go for a walk in the woods and take a look at one of the earliest forms of woodland management.

Coppicing is a traditional method of woodland management which takes advantage of the fact that many trees produce new growth from the stump or roots if they are cut down. Coppice stools have multiple stems growing out of previously cut stools which arise from dormant buds on the stool. The resulting structure looks like this.

Regrowth from a coppice stool

Most frequently coppiced species are oak, hazel, ash, willow, field maple and sweet chestnut. In this woodland, most of the coppice is hazel but management has lapsed and many of the stools are in need of management to bring them back into the coppice cycle.

Stools such as this one have been allowed to regrow for too long.

Coppicing allows for the production of a large quantity of fast growing, sustainable timber products without the need for replanting. Although trees can be grown from seed, coppicing allows the tree to regrow from a fully established root system.

Different species respond differently to coppicing. Some species such as alder and beech coppice poorly, while species such as hazel and willow respond very well, quickly sending up vigorous, straight growth which can be utilised in a range of ways.

Most notable in this woodland is the way that the coppice affects the general feel of the woodland area. In traditional broad leaf woodland, the canopy is usually quite high and the understorey more sparse than in a coppice woodland. Here, especially now that the leaves are out, there is much more vegetation at eye level than you would usually find in non-coppiced woodlands.

Looking up through the coppice canopy

We have said before that the structure of this woodland is “coppice with standards”. This means that there is a coppice understorey with scattered larger standard trees. These standards need to be sufficiently spaced apart to avoid shading the coppice.

The standards in this woodland are primarily oak and horse chestnut, however in some areas these trees have been allowed to grow too large and too close together and the coppice understorey has disappeared, out competed and overshadowed by the larger standards.

Hopefully, some of these lapsed coppice stools can be brought back into a coppice cycle in the near future.

If you would like to learn more about the fascinating history of coppicing which dates back to neolithic times, take a look at these links:
