Background:
The field site in Bokspits is the first of several sites we’ll be camping at in order to investigate root systems and structures.
Situation:
We’ll be excavating several different tree species at the Bokspits site in order to examine what role they play in water and carbon cycles here in the desert. We’ll be excavating or taking samples from the following trees:
|

Northern Range |
Central Range (% BA) |
Southern Range |

Pandamatenga |
Shrub: Rhus tenuinervis
Tree: Acacia erioloba |
Shrub: Combretum hereroense
Tree: Baikea plurijuga (~15%) |

Shrub: Grewia flava
Tree: Boscia albitrunca |

Shrub: Acacia. melifera
Tree: Acacia haematoxylon (~50%) |
Shrub: Grewia flava
Tree: Boscia. albitrunca |
Assignment:
Help to research several of the tree species that we’ll be excavating so that I’m aware of any potential factors that might influence the outcome of the research or help make collecting data a little easier. Also, if you can help to create a webpage that we can attach to this one about one of the plants, we’ll be able to give researchers a clearer view. Choose a plant from the list above and create a webpage that we can link to this one that shows:
- Pictures of the leaves, bark and flowers (if possible)
- Latin and common names that local folks have for this plant
- Any distinguishing characteristics that might help us to identify it
Hunter sondeen here. here are some quotes about the I.D. i found with a google search for th acacia mellifera from wikipedia: Acacia mellifera can manifest itself either as a multi-trunked bush up to seven meters high with more or less a funnel-shaped crown, but also as a small single-trunked tree, which can reach a height of up to nine meters. from www.worldagroforestrycentre.org: A. mellifera is a commonly occurring shrub on rangelands throughout the savannah in western, eastern and southern Africa. The terrain preference is rocky hillsides with rainfall along seasonal watercourses, mixed with other trees. If left unattended, especially if grazing is heavy and no fires check its spread, it may form dense, impenetrable thickets, 2-3 m high and sometimes hundreds of metres across for some reason, the two websites show two different height.
hey its hunter here is awebsite i found for the kuke shrub grewia flava http://www.sigridleger.de/book/index.html?/book/plants/pl_054.html
Stacy Here: I chose to look us the Acacia erioloba, and it used to be reffered to by the Acacia giraffae, because only giraffes would be able to graze on the hard to reach succulent leaves. A common name for it is the Camel thorn, because it has huge throns that grow from it, but i dont know where the camel part comes from. It can reach a hight of 17 meters, and it is a very dense and strong tree. The bark is a reddish brown colour, and it is a very extremely drought hardy plant. The seed pods that grow from it are ear shaped, and cattle usually graze upon that.

| cass- Grewia flava- Dense multi-stemmed shrub, up to 2 m tall, occasionally a taller small tree. Bark dark grey-brown; young branches velvety, becoming dark purple-black. Leaves alternate, often held upright, elliptic to oblanceolate-obovate, up to 7 × 2.5 cm, 3-veined from the almost symmetric base, grey-green above, paler below, finely hairy on both surfaces or more so below; margin finely to somewhat coarsely toothed. Flowers yellow fading to orange-brown, 1.5 cm in diameter, solitary or in few-flowered axillary heads. Fruit spherical or 2-lobed, c. 8 mm in diameter, reddish-brown when ripe, edible. | flava: yellow, referring to the flower colour, which is also yellow in many other species. |
| In dry deciduous woodland, often on Kalahari sand. | native to;
