Best Reforestations Techniques

By Liliana Usvat    
Blog 351-365


“A society grows great when old people plant trees, knowing that they will never sit in the shade of those trees.”  Based on an Ancient Greek proverb.

Reforestation on a grand scale is desperately needed in many places all around the world.  


Reforestation projects can create new patches of indigenous vegetation and/or increase the size of existing remnant patches of vegetation, and provide a buffer around them, as well as create linking corridors (particularly important for the dispersal of wildlife) between vegetation patches.


Usually only indigenous plants are used in reforestation .

Ideally, propagation materials are collected from within a few kilometres, but in practice seeds, cuttings, etc. are collected from within the same catchment, or within about 15 kilometres (a largely abitrary figure, although honeyeaters will travel around 15 kilometres, dispersing pollen in the process, Lindenmayer 2012). In the USA, propagation material is collected from up to 80 kilometres away (also an abritary figure?), which provides much more flexibility . 


In some places, the nearest remnant vegetation may be further away than that, so propagation material will have to come from the nearest practical source, and perhaps a few sources to provide sufficient biodiversity, and a wide gene pool. Some suggest that as a strategy or insurance against possible climate change, seeds could be sourced from both north and south of the area.

Degraded soils

Deep ripping of compacted degraded soils, or subsoil, can be helpful (using a tractor and ripper, or draft animals). Sometimes the soil is degraded as well as weed infested, in which case some of the species and techniques used in mixed improved fallows may be appropriate to improve the soil, shade out weeds, and kick start reforestation – see the “Fallows, Green Manure, Succession” page (click on the button at the top of this page), and the AID article on the “Articles” page. Livestock can also be used to partially control weeds and improve degraded soils.

Planting Trees

Nearly all reforestation projects involve planting mainly trees, grown in small square plastic tubes called tube stock (see photos below), into larger hand-dug holes (or an auger may be used), which are then watered in, usually with a little or no fertilizer added, and then mulched with “council” or “municipal” mulch (a composted mix of chipped wood and leaves, sourced from local government pruning of street trees, which has been at least partially composted, and which closely matches natural mulch/leaf litter in a natural forest).

 The mulch would normally be about 5 cm or more thick (2″ or more thick), and arranged in a circle around the plant, without touching the stem, about a metre/yard in diameter, or preferably the whole area is mulched. 


Direct seeding – utilizing livestock for reforestation/re vegetation


“Seeds and fruits are the chief, sometimes the only, food of many forest-inhabiting rodents.

Livestock and/or wildlife can be used to disperse seeds, providing a “work smart not hard” reforestation method for large areas, with treatments repeated over time. Livestock can also be used to restore degraded soils, or enhance the fertility and structure of average soils, through their manuring and urination.

Seeds can also be broadcast by hand or machine (but this is more labour and energy intensive), and then trodden into the soil by the animals, to enhance the germination and establishment of many plant species.

The Canopy Project

As part of its mission to protect natural lands and preserve the environment for all people, Earth Day Network developed The Canopy Project. Rather than focusing on large scale forestry, The Canopy Project plants trees that help communities - especially the world's impoverished communities - sustain themselves and their local economies. Trees reverse the impacts of land degradation and provide food, energy and income, helping communities to achieve long-term economic and environmental sustainability. Trees also filter the air and help stave off the effects of climate change.

Permaculture Reforestation

A forest plays an important role in ecological stability by serving as a natural water reservoir as well as a habitat of our wildlife and the indigenous tribes there within. Since our forests are mostly degraded, rehabilitating them is a lifetime activity. 


Regenerating a natural forest (Philippine Mahogany, Apitong, Lauan, Molave Narrra, Dao, and other indigenous species etc.) is usually done through seeds and wildlings, along with the knowledge of the local people. 

The development program follows something called the framework species concept, wherein the forest is planted with a select number of starting species which encourage the return of birds, animals, insects and provide the ecosystems services which set the stage for the natural regeneration of a truly diverse and healthy forest. 

A forest planted in this way can start with 30 varieties and see over 150 varieties of trees growing in less than 10 years. Our focus is not on the success of the trees themselves, but on the forest in general.


Logging

Stopping logging companies to destroy in a planned way the forests would be another help to the environment and climate change.

Trees of Mexico Red Gumbo Limbo Medicinal Uses for Skin affections Pain Colds Flu Sun Stroke, Blod Purifyer

Blog 350-365


Red Gumbo limbo (English), Chakah or Sip' che' (Maya), Bursera simaruba, Burseraceae family. Red Gumbo Limbo is native to the Americas; a deciduous tree most notable for it’s peeling deep reddish bark, and soft wood, nowadays use by Maya carvers.  Chaca's small white bloom clusters grow in spring and winter. 















This Gumbo limbo can be propagated by just planting young branches to the ground, Maya people use it as posts for fencing their parcels that with time become mature trees.  The Red Gumbo limbo or Chaca tree has a high salty soil tolerance and many medicinal qualities used by Maya healers in tea fusions, oils and anti-inflammatory ointments.

This large deciduous tree is most notable for it’s peeling reddish bark.
 
People use its resin as glue, varnish, water-repellent coating, and incense. Gumbo-limbo is considered medicinal nearly everyplace it grows.

TRIBAL AND HERBAL MEDICINE USES


Rosita Arvigo reports that the bark is a common topical remedy in Belize for skin affections like skin sores, measles, sunburn, insect bites and rashes. A bark decoction is also taken internally for urinary tract infections, pain, colds, flu, sun stroke, fevers and to purify the blood.
 
 A strip of bark about 4 -5 cm x 30 cm is boiled in a gallon of water for 10 minutes for this local remedy and then used topically or drunk as a tea.

When someone sprained an ankle or pulled a muscle, gumbo limbo resin was applied to the affected area.  I guess you just spread the sap on your skin and stick some leaves to it, twice a day, with meals.



WORLDWIDE MEDICAL USES
Bahamas for aches(back), debility, hunger, impotency, rashes, strains; as an aphrodisiac
Belize for colds, blood cleansing, fevers, flu, insect bites, measles, rashes, skin sores, sun stroke, sunburn, urinary tract infections
Dominican Republic for cystitis, intestinal problems, nephritis
Guatemala for aches(stomach), bite(snake), gangrene
Haiti as an antiseptic diuretic, insect repellant; for calculus, diarrhea, nephritis Sore, Vulnerary
Mexico for asthma, bite(snake), colic, dropsy, dysentery, enterorrhagia, fevers, stomachaches, swelling, venereal diseases, yellow fever; as an diaphoretic, diuretic, expectorant, purgative
Peru as an analgesic, blood purifier, diaphoretic, expectorant, insecticide; for rheumatism
Venezuela for cancer(stomach), corns, debility, hernia, rheumatism
Elsewhere for aches(stomach), muscle fatigue, obesity, renitis, rheumatism, tumors, venereal diseases, wounds

Reforestation

One reason the tree is so commonly encountered is that it's a tough, adaptable species able to endure many abuses. Just poke a stick of it into the ground, it roots, and makes a new tree. 


Cut off a branch, stick it in the ground, and it will grow.  People still make photosynthesizing fences by planting a row of branches.
 
Propagation is by seed which germinates readily if fresh but, most often, gumbo-limbo is propagated by cuttings of any size twig or branch. Huge truncheons (up to 12 inches in diameter) are planted in the ground where they sprout and grow into a tree. 

Be sure to properly prune and train a tree grown in this fashion, since many sprouts often develop along the trunk after planting. A tree left to grow in this manner usually develops weak branches which may fall from the tree as it grows older. Space major branches out along the main trunk to create a strong tree. It is probably best to plant seed-grown trees or those propagated from smaller, more traditionally-sized cuttings.

Trees of Mexico Guadalupe Palm

By Liliana Usvat    
Blog 349-365















Guadalupe Palm, Brahea Edulis, Arecaceae family. An endemic palm to Mexico, this lush small fan palm has shiny green fan-shaped leaves, usually with indentations along the midrib. Guadalupe palms grow to 9 meters high showing a highly fissures trunk 1-1/2 feet in diameter. Endangered in its own native habitat in Mexico, the Guadalupe Island, this beautiful palm is grown successfully nowadays in many palm farms, specially in the United State as an ornamental palm.
 
Named “edulis” for its edible fruit.

Brahea edulis (Guadalupe Palm, Palma de Guadalupe) is a palm endemic to Guadalupe Island, Mexico; a few stands have been planted elsewhere. It is a fan palm which grows 4.5–13 meters tall. It grows between 400 and 1000 meters above mean sea level. 
 
The entire native population consists of old trees with little successful recruitment for 150 years or so. Until recently, Guadalupe Island supported a large goat population (estimated at 100,000 in 1870, and 5,000 in 2000). 

The presence of these goats prevented regrowth of the native trees, including B. edulis, and as a consequence, the ecosystem was drastically altered: the once verdant island turned into an almost barren rock, with weeds replacing the former forests. Below 800–900 m ASL, the palm is essentially the only remaining tree, occurring in a major sub-population and scattered groups in sheltered locations.
 
 Above that, there used to be a band of mixed woodland where the palm was accompanied by Island Oak and Guadalupe Pine. This habitat has now all but disappeared due to the other trees becoming pushed back into higher regions. 

The species was probably declining slowly since the mid-19th century. Its range might even have expanded a bit until the mid-20th century however; part of it was shared with other trees as noted above; especially the pine, it's a towering species that presumably grew in many sites now occupied by the palm. 
 
In addition, a forest of Guadalupe Cypress and California Juniper shrubland existed in the palm's present range; the cypress forest was eventually destroyed by the goats and the juniper is nowadays completely absent from the island. Although endangered in the wild, B. edulis is cultivated, especially in California.  

Reforestation



Trees are quite wind and salt hardy. They thrive in drier subtropical conditions and don't do as well with constant humidity. Grow in almost any soil type, water is need infrequently, and once established, the plants need little or no care. Propagation: By seeds, which take 3-6 months to germinate. 
 
Guadalupe palms grow amidst indigenous Monterey pine, Pinus radiata var. binata; toyon, Heteromeles arbutifolia; sword fern, Polystichum munitum; California juniper, Juniperus californica; and members (some endemic) of such typically Californian genera as Cupressus (cypresses), Eschsholzia (California poppies), Ceanothus (California lilac), Arctostaphylos (manzanita), and Eriogonum (buckwheats).

To be accurate, Guadalupe palms used to grow with these plants, but many became endangered or were extirpated by more than a century of feral goat browsing. The destruction has now ended with the removal of the goats as part of a restoration project, and plants are responding with rapid growth.
