South Africa protects its national trees
15 January 2013
South Africa is home to more than 1 700 indigenous species of trees and shrubs,
some of which are threatened because of their rarity as well as the pressure of
commercial and subsistence use.
Currently, more than 70 trees and groups of trees have been declared national "Champion Trees" by the Department of Agriculture, Forestry and Fisheries,
which means they are fully protected under the National Forests Act of 1998.
Under the declaration, tree species listed as protected may not be cut, disturbed or
damaged and their products may not be owned, transported, exported or sold
without a licence. Once a tree is listed as a Champion, all trees of the species fall
under the protection of the Act.
"Listing certain species as protected is not primarily aimed at preventing the use of a tree species, but to ensure sustainable use through licensing control measures," says Champion Tree coordinator Izak van der
According to the department, such projects have been established in several countries, but this is the first of its kind in Africa.
Protecting trees of national conservation significance
The Champion Tree project of South Africa aims to list and protect trees of national
conservation significance. The project over the years has been about raising
awareness for the national tree heritage, and to promote it as an asset for tourism.
The first tree to be declared as protected under the Act in 2003 was an English oak
tree (Quercus robur
) in Sophiatown in Johannesburg. Estimated to be over a
century old, it was the only relic and landmark of the days before the residents were
forcibly relocated and the town was turned into a whites-only suburb under
The tree is of cultural significance because it was under its leafy branches that
residents and political activists used to gather for meetings.
Sophiatown oak tree was visible from several street blocks away, with a trunk
girth of 4.48 metres and a crown diameter of more than 30 metres.
The Act was materialised as an attempt to stop the destruction of the tree by a
property owner. The tree fell down in 2008 but its trunk can be seen at the Trevor

Other Champion Trees include two massive Australian Moreton Bay fig trees (Ficus
), one standing on the campus of the University of Cape Town and
the other inside the Pretoria Zoological Gardens.
Both these trees have a crown diameter of more than 40 metres, and trunk
circumference of more than 16 metres and 9 metres respectively.
In the Goudveld Forest near Knysna, Western Cape, one of the more recent
Champions has been renamed the Dalene Matthee Big Tree, as a tribute to the
author who wrote a best-seller series of historic novels about life in the
the 19th century.
Previously known as the Krisjan se Nek Big Tree, this Outeniqua yellowwood
), is nearly 900 years old and stands 40m tall.
The 1 000-year-old Wonderboom Wild Fig tree (Ficus salicifolia
), located in
Pretoria, has the largest crown of all the champion trees with a diameter of 61
metres, while in Limpopo stands the largest indigenous tree in South Africa - the
Sagole baobab tree (Adansonia digitata
) - with a trunk circumference of more
than 33 metres.
The Twin Giants of Woodbush State Forest in Magoebaskloof, Limpopo, are the
tallest of the lofty Saligna blue gum trees (Eucalyptus saligna
), and were
measured by professional tree climbers in 2008.
Africa's tallest trees
At a height of 79 metres, they tower above a 26-storey block of flats. Planted in
1926, they are the tallest trees in Africa, and according to the department, the tallest of
species anywhere in the world.
Category 1 invasive trees are dangerous species of trees that are not eligible to be
Champion trees and are therefore not protected; however, category 2 of invasive
trees, such as blue gum trees, are not dangerous and are therefore protected with
"The most outstanding find among the indigenous trees is a Lowveld cabbage tree
) towering above the canopy of a natural forest at the
Kurisa Moya Nature Lodge near Magoebaskloof," explains Van der Merwe.
This tree is about 35 metres tall and has a trunk circumference of 11.6 metres.
Another indigenous tree that has to be seen to be believed is a baobab on the farm
Swartwater in Limpopo. This tree has a trunk circumference of 24.5 metres.
The tallest indigenous tree on the list is an Outeniqua yellowwood of about 41
metres high, growing in the forests of the Blouberg Mountains in Limpopo.
However, the Outeniqua
yellowwoods of the Knysna forests draw many visitors, such
as the Tsitsikamma Big Tree, which receives more than 80 000 visitors a year.
"Exotic tree species introduced from other parts of the world tend to dominate the
Champion Tree list, with eucalypt species topping the list in terms of size," Van
der Merwe says.
"Many of these trees attain heights of more than 50 metres, such as a group
of newly listed eucalypts of various species in the KwaZulu-Natal Botanical Gardens."
According to Van der Merwe, pine trees seldom attain such heights, but a Loblolly
pine (Pinus taeda
) discovered on the Buffelsnek Forest Estate near Knysna by
tree climber Leon Visser, just about topped the 60 metre mark.
A group of false Weymouth pine trees (Pinus pseudostrobus
) was also added
to the list, growing about 50 metres tall and sporting trunk circumferences up to
Nominating trees to be protected
nominate indigenous or non-indigenous trees for Champion status.
According to Van der Merwe, trees can be listed according to size criteria like height
and trunk circumference, or according to value criteria such as historic value and
The nomination cycle starts on 1 August of each year, and ends on 31 July the
following year; thereafter the nominated trees are assessed by a panel of experts.
This panel assists the department with the shortlisting of trees, which are then published for
comment, and finally declared as protected.
Raising awareness with tree climbing
A team of international tree climbers arrived in South Africa on 4 January for a
month-long expedition to climb Champion Trees throughout the country. The aim of
this expedition is to climb about 20 of the largest and oldest Champion Trees.
They include several venerable yellowwood trees towering above the canopy of the
Knysna forests, giant baobabs such as
the iconic Sagole tree in Vendaland, the
Three Queens trio of Matumi trees (Breonadia salicina
) at Amorentia Estate
near Tzaneen, and the tallest tree in Africa, one of the Twin Giants of Woodbush
Like rock climbing, tree climbing is a potentially dangerous pastime practised by a
small and adventurous group of people, and it has caught on in South Africa too.
Local tree climbing enthusiasts like Visser will join the expedition on some of the
climbs. Stellenbosch resident Visser has in the past helped the department to measure the
height of very tall Champion Trees that cannot be reliably measured with instruments.
"Tree climbers have an ambition to climb the biggest and the oldest trees, and height
is not always the defining criterion," says Van der Merwe.
The Sagole baobab is only 22 metres tall, but a mathematic size formula determines
it as the largest indigenous tree in the country on the basis of its enormous 33
Apart from ticking off the largest trees on their tree climbing list, the team also
hopes to raise awareness of trees and the need to protect the tree heritage.
The department and the local Dendrological Society assisted with organising the tree climbing
expedition, and obtaining the necessary approval of various land owners and
