Air Meadows - Food for Free Part 9 - Pollarding and Pruning Tree Fodder (Part 2) | The Holistic Hen - How to raise quail, chickens and pigeons organically in a food forest

In part one of this article we looked at the rich heritage of tree fodder and how it had been used as a form of arboricultural farming for many thousands of years. In this article I want to look at the practice in detail with reference to the choice of individual species, their nutritional value and their suitability as fodder and medicinals for both poultry and other livestock. If you haven't read part One you can find it here.

Below, one of my quail snacking on the first flush of hornbeam. I noticed that the quail preferred to eat the flower buds of the tree first. When I consulted the detailed nutritional breakdown of hornbeam from the European Data Base, this gave me some insights into why that might be but more of this below.

Tree Fodder Air Meadows for Poultry & Livestock

The 17th century English Agricultural author, John Worlidge encouraged the planting of trees to be pollarded in hedgerows:

‘For Ash, Elm, Poplar, Willow, and fuch Trees that are quick of growth, it is a very great proﬁt that is made of them where Fewel is fcarce, by planting them in Hedge-rows, and other fpare places, and fhrouding them at ﬁve, fix, eight or ten years growth; they constantly bear a good head, and every time whilft the tree is in proof, the fhrouds increafe. They are out of the danger of the bite of Cattle, and require no fence’ (1669: 126).'

In France, many rural hedges still contain both ancient and newly planted pollards, now mostly for fuel rather than fodder, although this practice of using leaf fodder is now coming back with the growth of smallscale organic farming and permaculture. Pictured below in the background is a chateau driveway of ancient pollarded poplar, with a hedge of relatively new mixed deciduous pollards in the foreground field. Note the large tell-tale callouses or 'boilings' on the ancient poplars.

Tree Species Suitable for Pollarding or Pruning for Fresh Fodder or Tree Hay

I have avoided my natural aversion to pollarding by simply just pruning my trees for immediate consumption. That way I don't have to be haunted by gnarled fingers but can still supply my poultry with nutritious and readily-available forage. In a forest garden this is an absolute boon as I have no grass available for immediate consumption or of course, for hay. Any grass I have has to be brought in from neighbours' meadows and with the present increase in homesteading and food production, these 'set asides' are getting less and less common. It is worth remembering, in their wild forms, poultry rarely forage in open grass lands, they live in jungles and other wooded areas. It is also worth noting that many present day grass-fed livestock such as cattle, for example, started life as swamp and woodland dwellers, which is probably why the Neolithic farmers carried on the practice of silviculture and air meadows.

Throughout the centuries trees used and seen as excellent fodder crops in Europe were:

alder, Alnus glutinosa
ash, Fraxinus excelsior
aspen Populus tremula
beech, Fagus sylvatica
elm, Ulmus minor
hazel, Corylus avellana
hornbeam, Carpinus betulus (pictured below pruned by the poultry!)
poplar, Populus
white hawthorn, Crataegus punctata (below left)
willow, Salix

with

sweet chestnut, Castanea sativa and oak, Quercus robur mixed in with other leaves

That said specific countries, such as Norway, for example include other favourites, which they still use to this day such as:

goat willow, Salix caprea
pine Pinus
rowan, Sorbus aucuparia

Depending on your climate and native (or well-established) species of trees there are so many options to choose from when planning to grow these valuable forage crops. Researching of your local farming history should lead you to the best varieties to choose. I include below just a few examples from outside European and similar climate zones (such as parts of the USA and Canada), however, it would be really useful if you could share any experience or knowledge of good choices for trees for poultry, in the comment section, as those species included below are general livestock forages.

African small livestock farmers for example, have for centuries fed forage on a 'wild browse' basis rather than specifically cultivated leaves for such. The continent has nearly 10.000 species of trees of which 75% are suitable for livestock feeding. Just a few examples of trees popular in arboriculture for use in this respect being:

gum arabic (Acacia senegal)
whistling thorn (Acacia seyal)
yeheb nut (Cordeauxia edulis)

A few examples popular in Central America

hairy stamen leadtree (Leucaena trichandra)
red calliandra (Calliandra calothyrsu)
wild tamarind (Leucaena diversifolia)

The above are just a straw poll garnered from the net but I've included some links below to useful sites.

Poultry Specific Air Meadows?

My answer to this is; observation. With a forest garden we already have a good mix of trees both native and exotic to provide a smörgåsbord of leaves, flowers and fruit as potential fodder. We also have some prolific climbers, (more of the latter in a future post) and which are certainly part of the canopy and thus the air meadow. My philosophy has always been that poultry know more about what they should be eating than humans ever will. So I let them get on with it. By noting what is readily consumed at browse height, such as rose bush leaves, beech and hornbeam, I know their preferences. Just by watching what is and conversely what isn't, consumed when pruning, also informs me on my birds' choices in leaf fodder. For example wild clematis (above top) is prolific in leaf production and I was very gratified to find my hens eating them with gusto from the prunings.

Below: photograph of a quick walk around the garden looking for 'Nibble Test at Browse Height' evidence of what is and what isn't to the taste of our poultry.

Tree Fodder Zero Waste

After the birds have eaten the leaves, buds and any other bits they fancy the twigs are then left to dry and later used in our rocket stove from which we get hot coffee and food and on a cold day (or even a hot one) under which the chickens like to 'sunbathe'.

Nutritional Value

In my previous article on the subject of leaf fodder, I actually went into quite some detail as to the nutritional value of leaves such as hornbeam and beech and you can find this linked in the related articles below. Listed at the end of this article you can also find an incredibly useful resource: European Data Base which you can use for the trees existing on your land or to give you an idea of those that would be useful fodder. Below is a screen shot of just a small part of the data sampling at various times of year for the first tree in my list - alder (Alnus glutinosa). This, to give you an idea of how useful this rich resource can be when planning your air meadow. You can also set certain parameters within the search to look at specific food values, which can inform your choice of tree or shrub.

There is also a link below to a Tropical Tree Forages List and the Forage Trees of Nepal which includes nutritional breakdowns and traditional uses. It is interesting to note also that in some countries there are still communal forests where livestock can be fed tree fodder and where branches can be cut for tree hay.

Tree Fodder as a Medicinal

Researching this subject you quickly realise that trees have a long and worldwide history of uses in medicine from heart treatments (hawthorn) and anti-inflammatory properties (Ash and Alder) to anti-bacterial (Beech) and painkilling properties (Willow). I've already mentioned sheep self-medicating for parasites, and seemingly it is the high tannin oak leaves that they choose. If you look at the uses of tree leaves in tisanes or herbal teas, again you will find a wide range of properties from poultices to the treatment of respiratory conditions. As always I observe my poultry to see what they are consuming at any given time of year because often tree leaves provide vitamins and minerals that may be lacking or scarce in other forages. For example pine needles contain a high amount of vitamin C, which is one of the first vitamins to be lost when the body is under stress (such as is caused by extremes of temperature), I have seen my poultry pecking at the needles in Winter and at the new growth pine buds in early Spring.

Small Scale Air Meadows - Maximising your vertical growing space

The other consideration in growing trees for your poultry is to remember that many of them produce not just leaves which are edible but also blossoms and fruit. However, the leaves of certain fruit trees, in particular stone fruit are viewed with caution, as in some of the literature, I have read they are considered toxic. I've found varying and contradictory reports on this however. I've even seen peach leaves mentioned as toxic and here in North Western France we make peach leaf wine. Conversely I've seen elderberry and mulberry mentioned as suitable forages but my birds will touch neither. So before you plant consider both searching for hands-on testimony and the 'Nibble test' and seek out some sample foliage.

One example of an incredibly valuable 'multi-forage' tree in our garden is Amelanchier or Serviceberry also known Saskatoon, an anglicisation of the Cree; misâskwatômina, meaning 'the fruit of the tree of many branches'. Mixed with tallow the dried berries, makes an incredible Winter survival food and as such was highly prized by the First Nations. It also has the advantage of being a very pretty tree both in blossom and in leaf, although you do not get the full idea from my image captured yesterday of the last few remaining petals.

My birds, love its petals, they eat every single one that drops to the earth and if it wasn't for the thorny Kiftsgate rose growing through it, I'm sure they would be up the tree snacking on them up there. The blackbirds however often beat both the chickens and ourselves to a major share of the berries. It's always a good gauge of the value of a plant when such fierce competition occurs. The foliage is a fodder crop both for wild deer, rabbits and livestock.

Amelanchier has not only nutritional benefits but it has been used in traditional medicine for thousands of years. It is particularly prized for its antioxidants, specifically phenolics, flavonols and anthocyanins, with the latter at a higher level than most other berry fruits. This however is just one example, use the links provided to check for more possibilities!

Here's the film:

As already expressed my intention is to continue this theme with a look at harvesting tree hay for poultry (this will be in June), before then however, another article in this series will look at climbing plants for air meadows.
