Wild Food & Natural Resources Course - May - Set One

Firstly, apologies for the delay. I hope you find this set another delicious addition to your wild food and natural resources knowledge base. Spring is still upon us with flowers blooming and buds bursting. I hope you are continuing to take note of the progress of all other species we have covered to date. So without delay, here we go.

Plant - Three Cornered Leek (Wild Onion)


Another of the Allium (garlic & onion) family, the Three Cornered Leek has a fantastic flavour with complements Wild Garlic both cooked and raw. At this time, it should be in flower and is hence easily identified from a distance. The white flowers and long stems and leaves make them appear like pale bluebells, with which they can often grow. The leaves, though subtly distinct are similar, but the cross section of the stems is the real give away. Now you can see how it gets its name.


Tree - Oak


I'm quite sure you know the leaf of the oak as well as the distinct acorns, however, there are other aspects of trees which are to be noted at this time, in addition to habitat, these are most notably bark and branch structure which as we discussed, are the purest of forms of identification, since they don't rely on leaf, bud or flower. The problem with learning this method is a requirement to have positive identification in the first place. Often, autumn leaves are left scattered at the base of trees, but with wind can take move them around and in crowded woodland, mistakes can be made.

Here is a clue to positive identification, a cluster of leaves forming from nobbly buds which may still be visible and worth noting for future identification. The leaves are curled and pale, but identifiable as those of an oak at closer inspection. 

Once noted, start taking paces back and widening you view to that of the branch and tree structure which you will note as distinct and familiar. The branches are gnarled and twisted. The tree is sometimes wider than it is tall and has an air strength and age about it.

As a climax forest tree, when mature, it often stands in its own ground with little around it. It can also be found alone in field or meadow, being much older than the grassland which surrounds it. You should be able to spot oaks at a distance and also when young, since the leaves at this stage are of a quite distinct colour. Once this identification has been established, start taking note of the bark.

Oak is an excellent firewood, but heavy and the calorie expenditure of carrying over large distances should be take into consideration. Though a strong building material, the branches are seldom straight and if others are available, it's better served as firewood for heating and cooking. 

The acorns are nutritious, but riddled with tannins, and are thus inedible unless treated. Boiling with multiple changes of water until it stays clear is one method, and boiling is another. Personally, I think acorns taste a bit rubbish, but make a worthy addition to a stew if crushed or powdered and provide fats and protein. 

Fungus - Fairy Ring Champignon


We've previously covered quite distinct fungi, but now that summer is drawing closer, things start to get a bit more interesting, with more and more species available there are more to be confused with and so more care has to be taken. It is now that we have to start learning some of the characteristics of fungi and with the an ability to distinguish between the good guys and the bad which to the untrained eye can look rather similar. 

Let us take the delicious Fairy Ring Champignon and rather deadly Fool's Funnel. They are both the same size and grow in the same habitat (grass) at similar times of year. Although champignon tend to grow in rings, this can be invaded by funnels and so one might lead to another. Both have similar (well, not really) caps and both have a rather long, thin, bare stem (or stipe). Both have thin flesh and similar looking gills and both spore white (more on this in another article). So what are the distinguishing characteristics? 

The Fool's Funnel is slightly depressed in the centre making it a little funnel shaped (no, really?) as compared to the Champignon which is flat to convex and when mature, has a raised spot (umbo) in the centre. The funnel is a dirty white and and the champignon is more of a tawny cream or ochre. The gills of the champignon are pronouncedly wide and the funnel gills can be slightly decurrent, that is to say that they draw down to stem a little, though the champignon gills do touch the stem.Now here is the challenge. From the above descriptions can you picture the two mushrooms, and importantly, mentally highlight the differences. Read back a couple of times before clicking on the following links to take a look.

Fairy Ring Champignon
Fool's Funnel

How did you do? Do you think you can identify both of these with 100% confidence? If not, then like any other edible, do not eat them and clearly don't eat the inedible ones. It is imperative that you are without doubt before consumption. Take some time to identify, photograph and double check the mushrooms you find and with time you will gain confidence.

One final note on Fairy Ring Champignon; they absolutely MUST BE COOKED as like Morels, they are poisonous otherwise. The stems are tough; to be discarded and the caps can be wind dried if you have an excess.

Happy foraging and keep an eye out for complementarity articles.


REMEMBER: Do no pick or eat anything you can't positively identify as safe and legal. 


NOTE: This article was written from a UK perspective and identification will almost certainly differ in other places around the world. Seek local advice to confirm positive identification.

Wild Food & Natural Resources Course - April - Set Two

Welcome back to the fourth set of plants, trees and fungi in what is turning out to be quite a popular course. If you've missed anything so far, take a look back through the archive and see what you can find. This set is a little bit late because my chosen fungi, the St George's Mushroom has decided to come out late and so I was unable to get a photo. Thankfully, fellow forager, Alan Smylie, was able to find some on his local site and has dropped me down a picture. So let's just get on with it, shall we.

Plant - Ramsoms (Wild Garlic)

Ramsoms (budding) and Nettles
Wild garlic has been out for a couple of weeks here, but has not flowered. It has distinctive leaves with a flat surface and unlike Lily of the Valley, with which it can be confused, it has no definite ribs. The petals are also pointy (not shown), as opposed to bell-like. The most distinctive distinguishing characteristic, however, is that is SMELLS LIKE GARLIC!

We can eat all of this plant raw or cooked from the leaves, stems, buds, flowers to the bulb. I personally prefer it to cultivated garlic as it has a fresher taste which does not linger.

As a bulb species, they can be found in patches and normally speaking, if you find one, you'll find hundreds. Favouring partial shade, they can be found at the edges of woodland. A good indicator species for Wild Garlic is Bluebells, which needs similar growing conditions. Bluebells are often more prolific, so you're likely to see them first, not only because of their distinct colouration. Like Bluebells and other bulb species they come and go quickly because the newly forming canopy of the woodland soon restricts the sunlight.

Tree - Silver Birch

Arguably the method of tree identification which applies all year is that of bark identification. Without buds or leaves, branch structure and bark are the only characteristics available to us. As with other trees and plants, over time we get used to the less distinct features, but in some cases, we don't have to, as they are quite distinct already. That is the case with the Birch.

Silver Birch
Birch is that white one with the bark that comes off in horizontal strips. There are really no other trees in temperate woodland that look like it. At this time of year the leaves are either not showing or they are small and indistinct, however, even at a distance, this tree sticks out like someone has painted it white and can be seen clearly at a distance. You don't generally find these as a majority occupier of woodland, rather that they pop up here and there amongst other deciduous trees.

The sap, which rises in early Spring, is a source of fluids and sugars, can be extracted by tapping. There are a billion videos on youtube, but be warned, it's not the elixir people make it out to be. It's a lot of effort for slightly sugary water.

As a relatively hard wood, with a straight, limited branching structure, Birch is an excellent construction material as well as a good firewood.

In addition, the bark is steeped in oils which are superb for fire lighting and almost impervious to rain water and are hence a favourite amongst bushcrafters. When stripped or roughed, it takes a spark easily. Taking the bark is simple and does not need a knife. See the article Birch Bite for my moan about people killing Birch by cutting and peeling the bark aggressively. The oils within the bark can  be extracted as tar which has been used as an adhesive, waterproofing agent, tanning agent and disinfectant. As a useful resource, it's worth removing all of the bark from branches you intend to burn, not only because it burns with an annoying black smoke. If removed in large sheets, the bark can be used to make containers and if really quite big, a canoe or coracle.

Fungus - St. George's Mushroom

Still early season for mushrooms and other Fungi, the St George is the first of the really tasty ones. As a proper looking mushroom, however, it's time to get a but more strict on identification. Thankfully, this early in the season there are not many confusion species. St. George's only grows in Spring, around St George's Day, so if you think you've found on in October, you've not. It is absolutely imperative that you do not eat any fungi you can't 100% positively identify.

St. George's Mushroom
The many gills are on the underside of a rounded, mostly white/pale, mostly smooth cap which can measure between 5 and 15cm. The stem is largely smooth and widens towards the base. The spore print is white. That is to say it if you leave a cap on a black piece of paper for a few hours, it'll leave a print of white spore. It also smells of grain, or say leather or cucumber.

It is important when learning new fungi of this nature, that we follow all of the steps to identifying the mushroom. Only with constant repetition of this process will we gain confidence in identification.

St. George lives on the ground, in the grass forming rings, many feet wide. My foraging friend, who also supplied the photo, pointed out to me that the ring has another characteristic; it affects the grass, which appears darker green. As this mushrooms forms a symbiotic relationship with trees, it's is found exclusively close by to them; normally Ash, which we know from a previous article. Other indicator species are Ramsoms and Bluebells. This whole package makes finding them a lot easier than simply looking everywhere.

As Spring continues, there are other treats available. It would be folly for me to publish them all, as it would be as overloading as a book. Keep your eyes peeled and remember all that we've learned. Repetition and confirmation are the key.

Happy foraging and keep an eye out for complementarity articles.

REMEMBER: Do no pick or eat anything you can't positively identify as safe and legal.

Birch Bite

You know what pisses me off? People who don't know how to get hold of birch bark properly.

YOU DON'T HAVE TO USE A KNIFE

The Birch naturally sheds its bark and there is a simple rule you can use to harvest birch bark:

IF YOU CAN'T TAKE IT OFF WITH YOUR FINGERS, LEAVE IT ON THE TREE

I was working in some woodlands recently which was open to use by a number of groups. I hadn't been there for over a six months. I arrived with a party of clients and was absolutely speechless when faced with what is basically Birch Rape.

Just to put things into context, this mixed woodland spans some 30 acres and there are more birch trees than you can count. I stood in the middle of an open area and lost count of the number of trees which had been stripped this way. Then I started to count the dead ones.

That's what happens to trees if you strip the bark off of them, they die.

The bark not only protects the tree from disease, but the inner bark, or phloem, is responsible for transporting nutrients around the tree, and particularly to the roots. Without this transport mechanism, the tree simply dies.

This process in agriculture is known as girdling and is used to force nutrients to fruit at the expense of a branch, but not a whole tree. It would be false ecomony to grow a tree for years, just to kill it for one season of fruits.

In nature, trees can die this way when deer, say, strip bark. This is why you see those protective plastic strips around new trees. Sometimes, entire fences are erected.

This is an issue that really gets on my nerves because it's senseless. You don't need an A4 sheet of bark to light a fire, the outer stuff that is being shed lights easier than the tough layers which need preparation and there is always plenty of bark on a single tree, let alone multiple trees. So there is no need to get the knife out and gouge off chunks of bark, save that for the Birch which has already fallen. You'll find, however, that it's far easier collect a little that's been shed from a live tree. So easy, in fact, that a child can manage it.
