However, these mountains erupt to the time when the human population is still very small. Meanwhile, when Krakatoa erupted, the human population is quite dense, science and technology has evolved, the telegraph was invented, and the submarine cable is installed. Thus it can be said that the current information technology is growing and developing rapidly.
Noted that the eruption of Krakatoa was the first major disaster in the world after the discovery of the underwater telegraph.

But in the area can be found pioneer plants such as reed (Saccharum spontaneum) that symbiosis with Azospirillum lippoferrum. At the bottom of which has been overgrown with reeds in a process of weathering of sand around which later grew kinds Melastoma affine and other types of plants. Based on existing records, there are currently some 206 plant species as there are fungi, 13 species Lichenes, 61 species of ferns, and 257 kinds of Spermatophyta.
