Some Information About the Mpingo Tree The African blackwood tree is a member of the rosewood family, with taxonomic classification in the family Leguminosae, genus Dalbergia, species melanoxylon.

Its name refers to the dark color of its heartwood, which appears black and is derived from the Greek mela, or melanos, which means black. The Swahili language used in Tanzania gives it the name mpingo.

Historically, it seems that mpingo is the African ebony of antiquity, referred to in records dating to Egyptian times.

In today's terminology the name 'ebony' is commonly used for a different species, Diosporos spp. Apparently, it is only in the last several centuries that the name ebony has been associated with Diosporos spp.

African blackwood is also referred to as Grenadilla in the woodwind instrument trade, though this name of Spanish origin likely refers to a wood of Central American origin. Cocuswood, from the Caribbean, was the wood of choice for woodwind instruments until aboutwhen it was effectively logged out as a commercial species and the alternative found to replace it was East African Ebony, or African Blackwood.

Robert Lamb, who was a consultant on the "Tree of Music" video and appeared in the film, writes about this confusion between ebony and African blackwood, "A sunken vessel was found somewhere in the Eastern Mediterranean with a cargo of among other things wooden billets that were analysed as blackwood.

The key thing is that the cargo manifest was also found with the vessel carved on a clay tablet in Egyptian hieroglyphics, listing ebony as part of the cargo. The hieroglyphics transliterate as HBNI and the etymology of "ebony" is from Egyptian via Greek, so this is fairly solid evidence I think.

Tomb artifacts from pyramid burials are mpingo in every case I've heard of where they checked this out with spectography. It is found in the drier parts of the country, apart from desert scrub, and can be frequently found in mixed deciduous forest, but less so in Western miombo lowland woodland country.

Its leaves provide fodder for the great migrating herds along the Serengeti plain; its roots have a nitrogen-fixing effect and so serve to increase the soil's fertility. The more mature trees have the ability to survive the sweeping grass fires which occur in the area.

An mpingo seed which has recently sprouted its first primary leaves is shown in the photo at left.

Mpingo does not grow in thick stands or under closed cover but prefers a more solitary existence, often taking hold in rocky and infertile soils where other plants cannot survive. This characteristic seems to derive from its inability to compete successfully with other plants.

During its early years it develops an extensive system of roots to sustain its life during the long months of the African dry season. Its growth is incremental; it takes years to attain a usable size.

Most trees do not exceed a height of 9 m. Some prize specimens have been reported with a 1 m.

Most blackwood is harvested from these two countries. Smaller stands are also found in southern and eastern Africa: Because of the recent long civil war in Mozambique, much of the mpingo harvest has come from Tanzania over the last 20 years.

Now that the war has ended, it is expected that an increased tourist trade will create a greater demand for carvings made of the wood, and stands of mpingo in Mozambique will again be utilized for commercial purposes.

In Tanzania, most of the information available suggests that the occurrence of the species is becoming more scattered and its abundance is decreasing. Once considered plentiful in the s, carvers now have to make extended journeys from their local villages in order to find suitable mature trees large enough for their work.

There are reports that woodcarvers in Malawi and Kenyafinding it increasingly difficult to obtain adequate supplies of wood, are now importing it in some cases. International companies which log the wood for the instrument industry are having to travel longer distances for suitable wood as well.

Botanists are concerned that, with consistent logging of only large trees with a straight bole, the genetic strain itself is becoming inferior since seeds from such prime specimens are increasingly less available.

These economic realities simply increase the danger of illegal felling in protected areas. It is a protected species in Tanzania, but the country lacks the resources to enforce the laws limiting its use. Despite these numerous signs of its decline there have been few initiatives attempting to regulate trade or to plant sustainable forests.Environmental Awareness - Naturalist Intelligence Environment is the area in which we live and grupobittia.com thin layer of air that surrounds our planet that supports grupobittia.com are the only kind of life that we know of that exists in our universe.

Besides Sphaeropsis (Diplodia) tip blight, common pine diseases found in the Chicago area are pine wilt, Dothistroma needlecast, and Lophodermium needlecast. Pine wilt is a serious disease caused by the pinewood nematode, Bursaphelenchus xylophilus. The Sweet Gum tree is the sand spur of the forest.

You painfully find them with your feet. The vicious seed pods have impaled many a forager and has done much to ruin the Sweet Gum’s reputation. Perhaps it is time for some rehabilitation. The only edible part of the tree is the dried sap [ ]. Arbor Day (or Arbour; from the Latin arbor, meaning tree) is a holiday in which individuals and groups are encouraged to plant trees.

Today, many countries observe such a holiday. Though usually observed in the spring, the date varies, depending on climate and suitable planting season. The most recent National Prescription Drug Take-Back Day was Saturday, April 28, , to provide a safe, convenient, and responsible means of disposing of prescription drugs, while also educating the general public about the potential for abuse of medications.
