The major aims of this contribution are to describe the state of vegetation and flora in the period 1989 to 1991 and to re-assess the development of both over the last ten years in comparison with data from earlier surveys. In addition, the paper

The three Krakatau islands in Indonesia were completely denuded by the great eruption in 1883. One century after the eruption, the vegetation of Rakata on the one hand and of Panjang and Sertung on the other are quite different. In this paper
, the A. describes two cases of long-existing vegetation in the course of a succession, and seek out the mechanisms of the long existence.

space puts restriction on population sizes, and time, together with isolation, is setting limits on the evolution of diversity. The paper gives examples by comparing vegetation processes in the Krakatau islands with those in Hawaii.

Ten years of quantitative studies of forests on Krakatau demonstrate the vegetational difference resulting from multiple successional pathways. Multivariate analysis of the forest data indicates strong statistical separation of forest types within

Photographs of the vegetated North and East Forelands of Anak Krakatau, which emerged from the sea in 1930 and was totally devastated by volcanic activity in 1952/53, provide some evidence of rate of change of plant cover from grassland to woodland
between 1971 and 1991. The series of photographs demonstrate that vegetational stages of the two forelands have not been synchronous and suggest that the North Foreland is lagging the East Foreland by about 12 years.

Species assemblage data from the Krakatau Islands are presented for the period 1883 to 1989. With the exception of the strand-line, no component of the Krakatau flora or vegetation has yet approached a stable composition. Both floral and faunal
