The slopes of Mount Ayanganna are covered in tall-canopy lower montane forest, up to about 1100 metres.

[3] Above this elevation, there is a series of "steps" – relatively flat plateaus separated by steeper slopes.

The poorly drained plateaus support low-canopy forest or terrestrial bromeliads.

[4] Mount Ayanganna is fully within Guyanese territory and is surrounded by rainforest.

In 1966, the national flag was planted on Mount Ayanganna to commemorate Independence.
