Botanical Identification
Ecology
The ecology of Sclerocarya birrea is characterized by its adaptability to diverse landscapes, spanning a significant altitudinal gradient from as low as 5 m to a maximum of 1700 m AMSL. It thrives within a variety of specialized environments, commonly inhabiting wooded grasslands, riverine woodlands, and dense bushland situated on rocky hills. This broad distribution across varying elevations and distinct vegetation types allows the species to occupy multiple ecological niches within its range.
- Elevational range max:
- 1700 m AMSL
- Elevational range min:
- 5 m AMSL
- Habitat :
- wooded grassland, riverine woodland, bushland on rocky hills
Life history
The life history of Sclerocarya birrea is characterized by its existence as a perennial species, ensuring its long-term presence within its ecosystem. As a phanerophyte, its reproductive buds are elevated well above the ground, typically supported by a robust woody structure. The plant exhibits a deciduous nature, shedding its foliage periodically as part of its seasonal survival strategy.
- Deciduousness :
- deciduous
- Life form :
- phanerophyte
- Lifecycle :
- perennial
Morphology
The morphology of Sclerocarya birrea is characterized by its growth form as a woody tree. It is a terrestrial, self-supporting species that functions as an independent organism, rather than acting as a parasite or an epiphyte. The plant exhibits significant vertical development, with a height that ranges from a minimum of 3 m to a maximum of 18 m, maintaining an average plant height of approximately 12.5 m.

- Parasite :
- independent
- Plant height max:
- 18 m
- Plant height mean:
- 12.5 m
- Plant height min:
- 3 m
- Woodiness :
- woody
Physiology
The physiology of Sclerocarya birrea is characterized by a standard C3 photosynthetic pathway, which facilitates carbon fixation through the direct carboxylation of ribulose-1,5-bisphosphate by the enzyme RuBisCO. This metabolic process is typical for many woody subtropical species, allowing the plant to optimize gas exchange and energy production under its native environmental conditions. Furthermore, the species does not function as a nitrogen fixer, meaning it lacks the symbiotic relationship with nitrogen-fixing bacteria required to convert atmospheric nitrogen into bioavailable forms, instead relying on the uptake of nitrogenous compounds directly from the soil through its root system.
- Nitrogen fixer :
- no
- Photosynthetic pathway :
- C3
Reproduction
The reproduction of Sclerocarya birrea is characterized by the production of drupe-type fruits that are indehiscent, meaning they do not split open at maturity to release their contents. The plant exhibits a reproductive strategy where self-fertilization is absent, suggesting a reliance on cross-pollination to ensure genetic diversity. The seeds produced vary significantly in size, with a recorded minimum mass of 0.43155 g and a maximum mass of 5.7 g, resulting in a mean seed mass of approximately 2.609025 g. Furthermore, the dispersal of these seeds follows a zoochorous syndrome, indicating that the plant relies on animals to aid in the movement and distribution of its seeds within its environment.
- Dehiscence :
- indehiscent
- Dispersal syndrome :
- zoochorous
- Fruit type :
- drupe
- Seed mass max:
- 5.7 g
- Seed mass mean:
- 2.609025 g
- Seed mass min:
- 0.43155 g
- Self fertilization :
- absent
