HIGHLAND TREE SPECIES
Flood Plain Acacia. Moist areas, medium sized 2-15m branching from base. Grows from 1,500-2,500min wooded grasslands and river valleys. Fast growing with green/yellow bark on young trees brown on old ones. Fuelwood, charcoal, tea from the bark and the pods are fodder for livestock and wildlife. Also an excellent source of forage for bees.
Flood Plain Acacia
Derivation of name and historical aspects
Eragrostis comes from the Greek eros meaning love and this possibly refers to the heart-shaped spikelets; agrostis means a grass. The species name superba is the Latin for splendid and is probably descriptive of the spikelets.
Perennial up to 1 m tall, erect or lower culms (stems) bent; inflorescence variable as it is either a contracted (narrow) or open panicle, when open, then branches long and flexuous. The common names are very descriptive of the spikelets which are large, being up to 16 mm long, flat, have jagged edges, green, often flushed purple and when mature, break off as a complete unit. Flowering time is from August to May.
Distribution and habitat
This grass is found from the Free State and Kwazulu-Natal northwards to the Sudan usually on sandy or gravel soils occasionally on clay. Found mainly in disturbed places in the veld and roadsides, also grows on termitaria.
Fever Tree or Naivasha Thorn. Acacia xanthophloea is a large tree, 15-25 m tall, with a crown that is somewhat spreading, branching fairly up the trunk. Bark smooth, slightly flaking, yellow to greenish-yellow.
Naivasha Thorn/Yellow Fever
Alkaline and volcanic soils, drought resistant, slow growing hardwood and large when mature. 5-21m tall, dark brown fissured bark. Amboseli and similar semi-arid environments.
Cenchrus ciliaris L
A small to medium-sized tree, growing to 17 m tall and a characteristic feature of the tree is its rust-coloured powdery bark. Grows well in arid and semi-arid areas. (Sidenote; the wood was used by ancient Egyptians to make the Pharaohs’ coffins).
Distribution and habitat
It occurs in the more arid parts of southern Africa and tropical Africa, the Mediterranean areas, and in Arabia to India. Introduced to Australia and other hot, drier areas of the world where it has been imported as cultivated pasture. Foxtail buffalo grass grows in dry, warm parts. It grows in all types of soil, but mostly in sandy soil and other well-drained soil types. It is often found along roadsides where it utilizes the additional runoff rainwater.
Derivation of name and historical aspects
Cenchrus is derived from the Greek word kegchros which means a kind of millet. The species epithet ciliaris is Latin and means like an eyelash, or short hairs, possibly alluding to the hairy bristles surrounding the spikelets. The genus Cenchrus has 22 species, tropical and warm temperate; 1 species indigenous and 3 species naturalised in southern Africa; C. ciliaris is the only widespread species.
Common in hot dry areas, especially on sandy soils where it is often ruderal (grows in waste places), and also often on termitaria, on all types of soil. Cenchrus ciliaris is wind-pollinated. It is adapted to fairly heavy grazing and a wide variety of conditions.
Cenchrus ciliaris is a palatable species with a high leaf production. It is one of the most popular cultivated pastures, especially in the more arid parts, with many commercially available cultivars. Foxtail buffalo grass can endure trampling.
A small tree, growing to about 2-6m high, occasionally becoming taller under optimal climatic conditions. The plant is usually low branched with a short stem and many upright twigs that form umbrella-shaped crown. The grey-barked Acacia senegal, which is a thorny leguminous tree produces the highest quality Gum Arabic.
A perennial shrub or tree, 2.5–10 (–20) m tall. Branches spreading, forming a dense flat or rounded crown with dark to black coloured stems. Bark thin, rough, fissured, deep red-brown. Thorns thin, straight, light-grey in young trees, mature trees commonly without thorns. Flowers prolific & golden yellow. Used as forage during drought, foliage and seeds are eaten by a wide range of herbivores. Highly valued as fodder and fuelwood in regions of semi-arid Africa and India. Used as a pioneer species in land rehabilitation and as a barrier to desertification. Non-forage/timber uses include gum/resin, tannin /dyestuff & traditional medicine.
Grows to 15 m tall, less frequently remaining as a shrub. Has deep roots; trunk to 20–30 cm in diameter; bark rough and fissured, grey to blackish brown or black; crown flat, umbrella-shaped or irregular, usually narrow and open. Thorns are paired abd grey, usually up to 1.5 cm long. Flowers are white or cream & scented. The bark can be used for making rope and twine, the leaves and pods are eaten by livestock. Acacia gerrardii is considered a useful tree in grazing land as it provides only light shade and does not depress growth of the fodder species beneath. The thorny branches are used to make fences for livestock enclosures (‘bomas’). The wood is used as timber, for carvings, small furniture, poles, posts, tool handles, for charcoal production, and as fuelwood. A soup is made from the bark. Honey bees feed on the flowers.
DRYLAND TREE SPECIES
SEEDBALLS from Kenya for East Africa
Indigenous tree & grass species suitable for East Africa
A common and wide-spread low and spreading Acacia species valued for charcoal, browse (both wildlife and domestic animals) and honey production. Acacia mellifera is commonly called Blackthorn or Wait-a-Bit thorn due to distinctive curved 'cats claw' thorns, useful as security barrier along fence-lines. It's considered a robust dryland tree, rarely exceeding 7m in height. Seeds are relatively large, germination and early growth is rapid.
Acacia abyssinica, known as the 'Paperbark acacia' is a mid to highland species (500-1800m) within semi-arid areas of East Africa. Is is a tall Acacia, up to 20m with flaky red to yellow bark, and is useful for wildlife browse, as well as wood and charcoal fuel. The white 'pompom' flowers are are favoured by bees. Abyssinica is quick to germinate with the onset of rains and co-exists well with other species of trees in a semi-arid environment.
Dombeya is a fast-growing highland hardwood, native to areas within East Africa between 1500 to 3000 m altitude. It's profuse seasonal flowering is of value to bees and the honey industry. Dombeya wood is used for fuel including charcoal, and a variety of traditional tools, including bows. Seeds germinate quickly upon distribution after the onset of rainy seasons and establish quickly. Dombeya trees are important for stabilizing soil in hilly terrain.
Please Note - The number of Seedballs per kilo in each bag will depend on the seed type. Some seeds are tiny, some much bigger.
A tufted perennial about 90 cm high and inflorescence about 15 cm long. Occurs at 0 – 1800 m Above sea level. It’s frequently found in bushed lands/dense bush. Prefers loose sandy loams and loams, but will grow on alluvial silts and rocky soils. Rainfall of about 575mm per annum. Drought tolerant. It prefers loose sandy loams and loams, but will grow on alluvial silts and rocky soils. Rainfall of about 575mm per annum. Drought tolerant.
Due to high germination capacity, the species fully covers the ground within a few seasons, and it It can be planted in mixtures with other range grasses such as Cenchrus ciliaris. It is highly palatable and is normally commonly overgrazed due to high
preference by livestock
