ความสัมพันธ์ระหว่างชนิดนก พันธุ์พืช และการจัดการสวนสาธารณะ เขตกรุงเทพมหานคร / วรัษยา สุนทรศารทูล = Relationships among birds, plants and park management in Bangkok / Varasaya Soonthornsarathool
The objectives of this thesis are to study the landscape management, plant species, bird diversity and the relationships between number of bird species found and environmental factors of four parks in the metropolitan area of Bangkok. They are Rommaneenart, Thonburirom, Queen Sirikit and Lumpini Parks. The parameters used are size of the park areas, number of tree species, total number of all plant species, the length of time that the parks were established, size of green areas, size of pond areas and number of visitors having activities in the park. It was found that the parks, new or old, were mainly designed and managed for the recreation purpose. The management did not emphasize on the appropriate and mutual use of man and birds. There were differences in the management of area used in term of the proportion of water area, construction area and green area among the parks. Most trees in all four parks could not serve as potential food sources and breeding sites for birds. Only 6-20% of trees could used as food for birds in some seasons and at some periods of time. The average numbers of bird species all year-round are significantly different among parks except in Queen Sirikit and Lumpini Parks. They were averaged 18 species in Rommaneenart, 25 in Thonburirom, 27 in Queen Sirikit and 29 in Lumpini parks. The diversity index of birds among the four parks is not significantly different and the linear correlation to all seven parameters are not found the results of this study could be used as a guideline and recommendation for the management of any public parks in order to increase the species diversity of birds and environment.
