Interesting Tree Projects from Around the World - The Canopy Project

The unique and exceptionally important Canopy Project was developed by the Earth Day Network as part of their initiative to protect and preserve the environment as well as numerous natural areas for the benefit of all communities.

Rather than focusing on the extensive re-establishment of compromised forest areas, their aim is to uplift disadvantaged communities by assisting them to establish food security and developing a sustainable economy by reversing the effect of land degradation through planting trees that provide food and energy resources as well as income for the whole community.

With the increase of devastating storms and floods which often lead to massive, destructive, landslides, stabilising ground through re-introducing or increasing tree coverage over large areas is vital.

For this reason, in 2012, the Earth Day Network along with the Global Poverty Project made a commitment to planting 10 million trees over a period of five years as part of their upliftment project in disadvantaged communities worldwide.

To date, the Canopy Project has planted over 1.5 million trees in disadvantaged communities in 18 countries.

In Haiti, where earthquakes caused massive landslides some years ago, a phenomenal 500,000 trees have already been planted while in three high poverty areas of Uganda, to provide local communities with soil stability, fuel, fencing and most importantly - food, 350,000 trees have been planted.

This fantastic project is making a huge difference to countless impoverished communities all over the world including countries such as the United States, Belgium, Mexico, Brazil, Australia, France, Canada, Spain and Japan to mention just a few.

This valuable project is supported by sponsors as well as individual donations and is part of a worldwide network of non-profit tree planting organizations.

The Canopy Project works in association with the United Nations Environment Programme’s ‘Billion Trees Campaign’ where every tree that is planted counts towards ‘A Billion Acts of Green’.

How are we able to help in our own communities? South Africa has numerous reforestation projects on the go, including Greenpop which we wrote about in our newsletter a few months ago. Read about it HERE. By donating to initiatives such as The Canopy Project or Greenpop, you will be making a significant contribution to helping our fragile environment become stronger and better equipped to support people.

Olea capensis (Black ironwood)

Although the splendid Olea capensis subs. macrocarpa may grow slowly, if planted in the right place, the shade of these breathtakingly handsome trees will be enjoyed for many generations to come as these trees can reach a great age. Second only in size, to the massive yellowwoods of the forests along the Southern Cape coastline, but not having suffered the extensive exploitation of the yellowwoods, these awe inspiring trees can reach an age of between 2000 and 3000 years. In the forest they can grow as tall as 35 – 40m but will rarely achieve that height in cultivation where a maximum of about 10m can be expected. The attractive panicles of sweetly scented flowers attract a variety of insects while the fruit is relished by birds as well as other wildlife.

LANDSCAPING USES
The Black ironwood is a most rewarding and beautiful shade tree but one should carefully consider the positioning of these trees before planting as they are slow to reach maturity and become a permanent fixture in the landscape. These must surely be amongst the finest of ornamental trees to plant as a legacy for future generations so it is important to ensure that wherever these trees are planted, there is enough space to enable them to grow unhindered, so that their full glory can be appreciated for many years to come. As specimen trees, Olea capensis subs. macrocarpa are unsurpassed or if you wish to create a truly imposing avenue, these trees will provide a permanent, evergreen thoroughfare for all to admire. The bonsai enthusiast will find the Black ironwood well worth the effort and challenge.
TREE SPECIFICATIONS
Height 6 - 10m
Spread
4 - 8 m
Deciduous/Evergreen
Evergreen
Growth Habit
The Black ironwood occurs in a wide variety of habitats but is most commonly found in moist to semi-moist high forest although in some regions they do grow in drier areas and bushveld.
Bark
On younger trees the bark is pale grey but becomes darker and vertically fissured as the tree ages. If the bark is damaged the wound exudes a distinctive dark gum.
Foliage
The glossy, medium to dark green, opposite leaves are paler green underneath and are narrowly elliptic, tapering at the base of the apex. The petiole is sometimes purple.
Flowers
The small, white or cream sweetly scented flowers are borne in abundant terminal heads from November to January. The flowers are bisexual.
Fruit
The fruit which is a fairly large, fleshy, oval drupe ripens to purplish black and looks similar to large Greek olives.
Seed
The seed consists of a brownish, oval pip inside the fruit.
GROWING REQUIREMENTS
Growing regions
The Black ironwood is widespread and grows in coastal forests from the Western Cape through to the Eastern Cape, up into Kwa-Zulu Natal and further north to Limpopo.
Growing conditions
Olea capensis subs. macrocarpa will grow successfully in shade or sun. As these trees grow rather slowly it helps to provide absolutely optimal conditions for the first few years by preparing a large hole before planting and enriching the soil with plenty of compost and high nitrogen organic fertilizer. Apply a thick layer of mulch around the tree and keep well watered.
Best season
 Spring - Summer
Hardiness
Black ironwood is hardy once established and will withstand some frost as well as dry conditions.
Propagation
Propagation from seed is quite a lengthy process as the seeds can take up to six months to germinate and the saplings grow quite slowly. Soft wood cuttings taken in spring usually provide a more successful and quicker method of propagation.
Growth rate
Slow
INTERESTING FEATURES
The name ironwood speaks for itself as the timber from these magnificent trees is extremely hard and heavy. The timber is grey-brown to brown with a fine straight grain and attractive yellow, black and grey figuring. This durable wood is oily and difficult to work but is excellent for turning and gives a beautiful, smooth finish. Previously, the wood was used for railway sleepers, wagon building, bridge construction and mine supports but increasingly this fine timber is gaining popularity for the manufacture of fine furniture, veneers and flooring.

Interesting Tree Projects from Around the World - Delhi - 'The Forest City'


Since the late 1990’s, the populous city of New Delhi in India has endeavoured to make Delhi a greener and more environmentally friendly place by restoring its diminishing forests to their former glory.

The city had lost much of its original forest to rampant urbanisation as well as through vandalism and neglect, with the result that large portions of the forest area had been destroyed or had deteriorated to such a great extent as to become wasteland. The damage had reached such huge proportions that in 1997, only 26 sq. km. of green cover remained.

Through the implementation of ambitious tree planting initiatives such as the ‘City Plants a Million Trees’ campaign and the hard work of the forestry department, the Isha Foundation and The New Delhi Municipal Corporation and Parks and Gardens department, the city managed to double the extent of the forest areas from 151 sq. km. in 2001 to 296.2 sq. km. by 2011.

Every year, through sheer hard work and dedication, the forest area increases significantly. By the end of 2012 the forested area had increased to 310 sq. km. and again in 2013 literally hundreds of thousands of tree saplings were planted making this one of the largest and most dynamic environmental greening initiatives in the world.

As the forest areas increase, birds and small wildlife return to the city, in fact, Delhi now boasts some 450 bird species within the city. Only Nairobi in Kenya which borders on the Serengeti National Park hosts more bird species within the city.

The citizens of Delhi are encouraged to take part in various tree planting initiatives and the city supplies the public with free tree saplings. Areas that are to be planted are cleaned, weeded, tilled, fertilised and watered before planting takes place.

After three years, the newly established forest begins to take care of itself and after five years the maturing woodland becomes completely self sustaining, supporting wildlife and providing welcome ‘lungs’ in the city as well as shade.

Although Delhi remains a city of congested traffic and masses of people, the green initiative is growing and is gradually overcoming the destruction caused by irresponsible urbanisation and land use through education, preservation and restoration of its green heritage.

Greenpop - Planting Trees for a Greener Tomorrow


Greenpop.org is an innovative organisation that have launched a hands - on volunteer project where South Africans, as well as tourists from around the world can become involved with the upliftment and environmental education of children in under-resourced areas of Cape Town.

Their aim is to offer volunteers the opportunity to assist with the greening of the urban environment through re-forestation with indigenous trees as well as the planting of fruit trees at schools, community centres and crèches, which will ultimately help to feed the children within these communities.

Volunteers also have the opportunity to help educate the children on the importance of preserving the natural environment and the role that they can play in conservation, as well as raising awareness of climate change and other environmental issues.

This is truly a ‘hands – on’ project as all volunteers are part of a team, helping with the actual planting of the trees alongside the children and other members of the community, while also helping with the mapping and monitoring of trees.

Not only is this a wonderful opportunity for South Africans to become involved with an important and rewarding project and interacting with international volunteers, but overseas volunteers are also be able to explore the magnificent city of Cape Town and immerse themselves in our colourful and diverse South African culture and hospitality.

Any healthy person of 17 years or older may volunteer for this worthwhile project that has already made great stride in making a positive and sustainable difference to the lives of countless children and all members of these under resourced communities.

TreeCo is an official sponsor of Greenpop and we have donated numerous trees in support of this initiative. http://www.greenpop.org/our-supporters/sponsors/
If you aren’t able to volunteer, but would like to support Greenpop, feel free to sponsor a tree through TreeCo, or discover how else you can help by visiting their website http://www.greenpop.org/

Curtisia dentata (Assegai)

Curtisia dentata is a very handsome, medium to large evergreen tree with a dense, well rounded crown. In forest conditions or when grown as a single specimen in shadier areas, the Assegai grows tall and stately but when planted in full sun, these lovely trees develop a particularly dense and bushy crown. The creamy white to red, bitter fruits are attractive to fruit eating birds with the bush dove and the lourie being mainly responsible for the distribution of the seeds. Curtisia dentata is a protected tree in South Africa as the numbers throughout the country have been severely depleted due to over exploitation, as the bark is highly prized in traditional medicine.
 
TREE DETAILS
Botanical Name
Curtisia dentata
Common Name
Assegai
Genus

LANDSCAPING USES
The magnificent Assegai is a truly excellent addition to the landscape. These superb trees can safely be planted in any built up or paved area as the roots are totally non-invasive. Another major advantage of planting these trees in an urban environment is that they create hardly any leaf litter while the tough branches ensure that they can withstand severe wind without any damage. These trees make superb specimen or shade trees while a tough, dense leafy screen or hedge can be created by planting a row along any sunny boundary or fence line. Where a landscape is being developed from scratch, Curtisia dentata will provide quick, long lasting and rewarding results.  
TREE SPECIFICATIONS
Height4 – 18 m
Spread
3 - 6 m

Growth Habit
Curtisia dentata is found growing naturally in coastal as well as montane forests throughout South Africa and Swaziland.
Bark
The bark on young trees is grey or reddish and smooth becoming dark as the tree matures with deep, somewhat squarish fissures.
Foliage
The mostly ovate leaves are simple, opposite, thin, leathery and without stipules. Young leaves are bronze and velvety while mature leaves are smooth, dark green above and grey green covered with red brown hairs below. The margins are sharply and strongly toothed.
Flowers
The small creamy flowers are inconspicuous and are borne in terminal sprays from October to March.
Fruit
The round to oval fleshy fruits, are roughly pea sized and are usually white, cream or reddish in colour. They are crowned with the remains of a persistent calyx.
Seed
The fruits contain a small, four chambered nut each of which usually contain a small seed.
GROWING REQUIREMENTS
Growing regions
The Assagai tree is found in the Western Cape and up along the east coast to the Eastern Cape, Kwa Zulu Natal, Mpumalanga, Limpopo and inland towards Swaziland.
Growing conditions
Curtisia dentata grows well in full sun or light shade. Plant in a deep hole to which generous quantities of compost and organic fertilizer have been added. Cover soil around the tree with a deep layer of mulch. Water generously for the first three years.
Best season
 Spring - autumn
Hardiness
The Assegai will withstand moderate drought once established. Very young trees are sensitive to frost and may lose their leaves but more mature trees will tolerate some frost.
Propagation
The seeds germinate readily. Remove the fleshy part of the fruit and sow the nut while still fresh. Keep warm and moist and the seeds should germinate within 3 – 4 weeks.
Growth rate
Fast, from 500mm to 1m per year.
INTERESTING FEATURES
The strong, durable timber of the Assegai tree is fine grained and has a reddish colour similar to mahogany. Over the years, this has led to the overexploitation of these magnificent trees as the wood was widely used for wagon making, floors, rafters and tool handles including assegais, as well as fine furniture and other household items. The bark is widely used for medicinal purposes such as the treatment of diarrhea, stomach ailments and as a blood purifier.

A Three Year Project of Note - The Reforestation of Africa


South Africa hosts many tree planting initiatives throughout the country annually, so it is interesting to see what is being done in other parts of Africa and the rest of the world, with regard to re-forestation and conservation programs.

Botanic Gardens Conservation International otherwise known as BGCI, is a UK based organisation that has become known as the largest plant conservation body in the world.

Their aim is to save the most threatened plant species in the world (some 8,753 tree species in 1998 and this will certainly have increased by now), through initiating conservation action and support for sustainable use, as well as educating local communities on the need for conservation and methods of propagation and replanting.
Aside from their numerous valuable projects throughout the world, BGCI has launched an important 3 year forest restoration and threatened tree species conservation initiative in Africa.

The aim is to promote the use of indigenous species while increasing the role of African botanic gardens in forest restoration.


Forest restoration using indigenous and threatened species will enhance biodiversity and will also benefit local communities by supplying food and medicine.

Most of the tree planting initiatives in Africa, focus on exotic species that deplete nutrients in the ground as well as compromising water supply. Through education and restoration of indigenous species, these issues can be resolved.

To provide a sound basis for extending re-forestation projects throughout Africa, Brackenhurst Botanic Garden in Kenya and Tooro Botanical Gardens in Uganda, both of which already have considerable experience in re-forestation projects, will be supported through training and education programs and the development of guidelines, which can be replicated in other African countries.

By forming partnerships with the private sector, NGO’s and governments, BGCI are making an invaluable contribution towards the prevention of extinctions and the re-forestation of the planet.
