The tree

Musanga cecrpioides, R, Br, & Tedla is a majestic tree and spectacular family Moraceae.

The trunk is straight, vertical up to 18-20 meters. The diameter is variable depending on tree age. At the foot of the trunk, we can find common roots in piloti air, as if this tree was a regular of wetlands,

The morphology of the foliage is typical and allows remote recognition that tree: the compound leaves are palmate. Their characteristic port fan-shaped . The leaflets may be up to 50 centimeters long by 10 centimeters wide).

Origin and area expansion

Musanga cecropioides is widespread in Africa, particularly Angola, Cameroon, Cote d'Ivoire, Democratic Republic of Congo, Ethiopia, Ghana, Liberia, Nigeria, Sierra Leone, Sudan, Togo, Uganda.

The reproduction of this tree is by seed. However, it appears that passage through the gut of certain animals is necessary (in particular, elephants and other animals as well).

Properties

Contrary to the prejudices, it would seem that the qualities of this tree fibers predisposes for use in paper pulp. The wood is sometimes used as a timber. The tree itself is often used as shade plants for stimulating forest (coffee and cocoa). This shade is a problem for many crops, farmers do not consider this tree as a tree to keep (not a tree "orphan"),

Environmental Status

On the environmental front, the tree is parasolier "pioneer" after clearing and burning of forests is one of the first recruits to appear (usually with Alchornea cordata and Dillenia reticulata, at least in the forest areas of Cameroon and Gabon). Subsequently, this tree, if not stifle all other plants, will disappear.

Photography

The photograph was taken in the late afternoon sun and calm. This explains the color tones of the photograph that transcribes the fading light and reports of significant shadows. The camera is set to aperture priority mode. The sensitivity is equivalent iso-200, with a focal length of 18 mm. Given the subject distance and to have a sufficient depth of field, aperture is the lowest offered by the lens, f/11, which allows the intense sunlight of the day. With these parameters the calculated speed is 1 / 100 th of a second.
