Tourist Sandy Beaches and the Effect on the Bird Diversity in Khao Sam Roi Yot National Park, Prachuap Khiri Khan Province

Abstract

This research aimed to compare the bird diversity at different sandy beaches with different tourism intensities in Khao Sam Roi Yot National Park, Prachuap Khiri Khan Province. The survey was conducted at 3 beaches over a period of 4 months in winter by the fixed point count technique for 20 days/beach. The collected data were analyzed to find the diversity index, evenness index, rank abundance curve as well as similarity coefficients; results were analyzed by one-way analysis of variance. The results revealed that
the diversity index of birds at Sam Phraya Beach was the highest. The similarity coefficient of each type of birds in each month at Don Ton Son Beach was the highest However, rank abundance curves of each type of the birds at Sam Phraya Beach and Don Ton Son Beach were similar; Don Ton Son Beach and Sam Phraya Beach had the same bird species with the highest similarity coefficients. The bird diversity at 3 beaches with different intensities of tourism in Khao Sam Roi Yot National Park was different when
tested at a significant figure of 0.01. Based on the above comparison, it is evident that beaches with different intensities of tourism in Khao Sam Roi Yot National Park, Prachuap Khiri Khan Province, exhibited different diversities of shorebirds.
