The Tree Walk held in the Crocodile River Reserve offered an insightful and easy to understand introduction to the day, starting with the structure of leaves and how to use this to identify a tree. What followed was a walk through the beautiful veld of the Reserve during which we identified a variety of trees – such as the fascinating underground tree Lannae Aedulis, the Diospyros Lycioides (Blue Bush), the common but beautiful Acacia Karroo (Sweet Thorn) and the Protea Caffra Trees but to name a few.
Trees and Shrubs of the Crocodile River Reserve
The ripe fruits of the Ximenia Caffra or Sourplum are eaten by birds such as barbets, bulbuls and starlings and mammals such as giraffe, impala, kudu, grey duiker, steenbok, bushbuck and eland enjoy eating it’s leaves. The larvae of a number of butterflies feed on the leaves, some examples being the Bush Scarlet butterfly, Natal and Silvery bar, Bowker’s and Saffron sapphire and the Brown playboy.
Lannea edulis has shiny green leaves that are hairy when young and leathery when matured, with creamy white flowers from August to October. It bears bright red ovoid berries from October to December that become purplish black when they become ripe, which have a juicy and pleasantly sour flavour and are eaten by mice, birds and humans.
The Buffalo Thorn Tree is widely used for magical and medicinal purposes because of the spines or thorns, which are paired; One is hooked, and the other is straight. According to Nguni legend, the thorns of the Ziziphus tell us something about ourselves – that we must look ahead to the future (straight thorns) but we must never forget where we have come from (hooked thorns).
