Edible Forest Gardening

Edible forest gardening is the art and science of putting plants together in woodlandlike patterns that forge mutually beneficial relationships, creating a garden ecosystem that is more than the sum of its parts. You can grow fruits, nuts, vegetables, herbs, mushrooms, other useful plants, and animals in a way that mimics natural ecosystems. You can create a beautiful, diverse, high-yield garden.

If designed with care and deep understanding of ecosystem function, you can also design a garden that is largely self-maintaining.

Design

Traditional agriculture involves 10% planning and 90% work.  Permaculture involves 90% planning with intelligent design and 10% work to implement the design and then much less work in maintanence.

Permaculture

Permaculture is theory of design which uses biological and ecological systems as models to create permanent and sustainable agricultural systems.

Permaculture  is Consciously designed landscapes which mimic the patterns and relationships found in nature, while yielding an abundance of food, fibre and energy for provision of local needs.’ People, their buildings and the ways in which they organise themselves are central to permaculture. Thus the permaculture vision of permanent or sustainable agriculture has evolved to one of permanent or sustainable culture.

History

The word permaculture was coined by Bill Mollison and David Holmgren in the mid-1970’s to describe an integrated, evolving system of perennial or self-perpetuating plant and animal species useful to man.

Plants are categorized by their place in the Forest Garden

Tall Trees Layer

Typically over 30 feet (~9 meters) high. This layer is for larger Forest Gardens. Timber trees, large nut trees, and nitrogen-fixing trees are the typical trees in this category. There are a number of larger fruiting trees that can be used here as well depending on the species, varieties, and root  stocks used.
  • Alder (Alnus species)
  • Apple (Malus domestica or pumila)

  • Cherry, Black (Prunus serotina)
  • Cherry, Sweet (Prunus avium)

  • Cherry, Tart (Sour) (Prunus cerasus)
  • Chestnut (Castanea species)
  • Lime, Linden, & Basswood (Tilia species)
  • Hazelnuts or Filberts (Corylus species)
  • Juniper (Juniperus species)
  • Monkey Puzzle Tree (Araucaria araucana)
  • Mulberry (Morus species: M. nigra, M. rubra, M. alba)
  • Oak (Quercus species)
  • Pears, Asian (Pyrus species)
  • Pecans and Hickories (Carya species)
  • Persimmon (Diospyros species: D. kaki, D. lotus, D. virginiana)
  • Walnut (Juglans nigra and Juglans regia)
  • Walnut - Other species (J. cinerea, J. ailantifolia var. cordiformi, J. x bixbyi)
Tall Shrubs

Typically 10-30 feet (3-9 meters) high. In most Forest Gardens, or at least those with limited space, these plants often make up the acting Canopy layer. The majority of fruit trees fall into this layer.
  • Cornelian Cherry (Cornus mas)
  • Elderberry (Sambucus species)
  • Jujube (Ziziphus zizyphus or jujuba)
  • Medlar (Mespilus germanica)
  • Pawpaw (Asimina triloba)
  • Pears, Asian (Pyrus species)
  • Plum (Prunus subgenus Prunus species)

  • Quince (Cydonia oblonga)
  • Sumac (Rhus species)
 Shrub Layer

Typically up to 10 feet (3 meters) high. The majority of fruiting bushes fall into this layer. Includes many nut, flowering, medicinal, and other beneficial plants as well.
  • Aronia or Chokeberry (Aronia species)
  • Blueberries (Vaccinium species)
  • Bougainvillea (Bougainvillea species)
  • Elderberry (Sambucus species)
  • Goji Berry (Wolfberry) (Lycium barbarum, Lycium chinense)
 
  • Gooseberries (Ribes uva-crispa)
  • Goumi (Elaeagnus multiflora)
  • Nanking Cherry (Prunus tomentosa)
  • Roses - An Introduction to Rose Types (Rosa species)
  • Roses - Rosa rugosa (Rosa rugosa)

  • Salal or Shallon (Gaultheria shallon)
  • Saskatoon (Amelanchier alnifolia)
  • Sea-Buckthorn (Hippophae rhamnoides)
 Herbaceous Layer

Plants in this layer die back to the ground every winter... if winters are cold enough, that is. They do not produce woody stems as the Shrub layer does. Many cullinary and medicinal herbs are in this layer. A large variety of other beneficial plants fall into this layer.
  • Asparagus (Asparagus officinalis)
  • Borage (Borago officinalis)
  • Chicory (Cichorium intybus)
  • Comfrey (Symphytum asperum)
  • Fennel (Foeniculum vulgare)
  • Good King Henry (Chenopodium bonus-henricus)
  • Hollyhock (Alcea rosea)
  • Horseradish (Amoracia rusticana)

  • Lupine (Lupinus species)
  • Oregano (Origanum vulgare)
  • Plantain (Plantago species)
  • Ramps (Allium tricoccum)
  • Rhubarb (Rheum species)
  • Sorrel (Rumex species)
  • Stinging Nettle (Urtica dioica)
  • Yarrow (Achillea species)
Climber Layer

These vining and climbing plants span multiple layers depending on how they are trained or what they climb all on their own. They are a great way to add more productivity to a small space, but be warned. Trying to pick grapes that have climbed up a 60 foot Walnut Tree can be interesting to say the least.
  • Hops (Humulus lupulus)
  • Kiwi - Tropical and Hardy (Actinidia deliciosa, A. arguta, A. kolomikta)

  • Malabar Spinach (Basella alba, Basella rubra)
  • Maypop (Passiflora incarnata)

  • Wisteria (Wisteria species)
Ground Cover Layer

There is some overlap with the Herbaceous layer and the Ground Cover layer; however plant in this layer are often shade tolerant, grow much closer to the ground, grow densely to fill bare patches of soil, and often can tolerate some foot traffic.
  • Aronia or Chokeberry (Aronia species)
  • Creeping Blueberry (Vaccinium crassifolim)
  • Groundcover Raspberry (Rubus nepalensis, R. pentalobus, R. tricolor)
  • Juniper (Juniperus species)
  • Lupine (Lupinus species)
  • Mint (Mentha species)

  • Oregano (Origanum vulgare)
  • Ostrich Fern (Matteuccia struthiopteris)
  • Rhubarb (Rheum species)
  • Salal or Shallon (Gaultheria shallon)
  • Sorrel (Rumex species)
  • Stinging Nettle (Urtica dioica)
  • Wild Angelica (Angelica silvestris)
  • Yarrow (Achillea species)
 Underground Layer

These are root crops. There are an amazing variety of edible roots that most people have never heard of, but I hope to introduce them to you here.
  • Groundnut (Apios americana 
  • Skirret (Sium sisarum)

Liliana Usvat: Forests in Canada

Forests in Canada

I am reading a book about forests in Canada. "At the Cutting Edge The Crisis in Canada's Forests" By Elisabeth May

I am amazed by the information provided in her book.

The forests is not protected against overcuting.
Forest dependent species such as the woodland caribou, spotted owl and pine marten are in trouble due to loss of habitat.

Deforestation around the world has global implications in reducing our planet ability to cope with the ever increasing release of carbon into our atmosphere. The technology exceed the ecosystems ability to recover.

In 1990 Greenpeace ran a newspaper ad. It pictured a clear -cut running as far as the eye could see.  below was the caption "They said we could never run out of cod either" referring to the fact that overfishing in Canada depleted the oceans of cod.

Canada is the world larger exporter of wood. In 2003 exports of forest products netted $40 billions.
Over 1 milion of people were employed to cut the forests in 2003.

Forests balance the climate, protect fresh water purify the air and provide food and shelter to myriad of species.

Out of 417,6 millions of hectares 294.7 millions are considered productive or commercial forest land meaning these ancient forest will be cut for the profit of few.

Like fishery, Canada's forest are largely a public resource publicly owned. Only 7% of Canadian forest is privately held compared with 70% in USA and Sweden.
 
The industry does not own the forest it logs.
Leases are cheap. Industry never pays the amount that ever approximate the commercial value in therms of the forest it converts in cash let alone its greater value in terms of ecological service.

Short term gain - logging the forest is subsidized while long term interests the sustainability of the resource itself and all other future values are heavily discounted.

For many years there has been virtually no public oversight of forest policy.

Leases come in a profusion of categories TFL, TSA, CAAF FMA
There are two type of leases based on specific areas and on designated volume.
Volume based leases tend to go to smaller operators while area based tenure arrangements tend to go to large companies.

Alberta Government decision to grant long term leases to two Japanese companies 5.8 millions of hectares respective 2.8 millions of hectares created alarm and media interest.

Sometimes is so sad to read these numbers and think the alarming facts that you are intrigued that more people are not aware of these facts.
