A tree of dry savanna and woodland
Umbrella thorn acacias grow in dry African landscapes, including East Africa. Here, the name covers trees in the genus Vachellia, including Vachellia tortilis, rather than identifying every illustrated tree as one species.
A canopy that offers shade
An umbrella thorn acacia spreads a wide canopy, creating shade on the sunny savanna. Its leaves and branches also provide resources for animals that browse or perch.
Three things to notice
- The spreading crown gives the tree its umbrella-like outline.
- Vachellia tortilis is one species represented by the name used on this page.
- The tree's branches hold leaves that browsing animals can eat.
Who uses the tree?
Shade for a resting lion
A lion can rest beneath the canopy. The tree offers shelter from direct sunshine.
Leaves for giraffes
Giraffes reach into acacia branches to eat leaves. Their long necks let them browse high above the ground.
Food for elephants
Savanna elephants eat acacia leaves and young branches. The tree is part of their varied plant diet.
