Otters Den Tree List

Otters Den trees


One of the special features of Otters Den is its great diversity of magnificent trees.  The soil varies from deep alluvium where towering jackalberries, quinine trees, natal mahogany and weeping boer bean form a closed canopy.  Next to the rapids, where bedrock dominates, evergreen trees including matumi,  water pear and waterberry form a dense gallery. Further from the water's edge, the riverine forest gives way to a transition zone with tamboti, apple leaf and ana trees.  Even further inland, one reaches dry woodland characterised by marula, leadwood, umbrella thorn and knob thorn. 

The list of indigenous trees of Otters Den was initiated by John Rushworth and Jason Stewart in 1995 when they catalogued 100 tree species in two days on the 50 hectare island. The list has since grown to 113 and observant treespotters may find a few more. For comparison, consider that in all of the British Isles one can only find 39 indigenous tree species.
