Introduction

Research Question

To What Extent does Hamo Beach, Jeju Island, Show a Typical Psammosere Model.

Background Knowledge

This investigation explores the characteristics of dunes in the Hamo beach as a psammosere. Psammosere, which refers to a vegetation development on sand dunes, is an example of ecological succession – specifically the primary succession. It links to ‘Option B: Oceans and their coastal margins’ of the IB Geography syllabus, focusing on the formation and development of sand dunes.

Referring to ​Figure 1.1, primary succession is an area that initially had little or no biological heritage but develops to establish a whole new ecosystem over time. Sand dune comes into this category as they have an arid, salty, and exposed environment, and it is a bare land with no protection for plants from strong winds sweeping from the sea, which leads to a lack of nutrients.
