ด้วยเวลาจำกัด ลองหาอ่านคร่าวๆ จาก http://www.nrdc.org/land/wilderness/fbios.asp

In order to be designated a biosphere reserve, a candidate ecosystem must be nominated by a national government and approved by the UNESCO's Man and Biosphere Programme. In order to satisfy UNESCO's program requirements, each biosphere reserve must contain three elements:

Core Areas: These areas are securely protected sites for conserving biological diversity, monitoring minimally disturbed ecosystems, and undertaking non-destructive research and other low-impact uses (such as education).

Buffer Zones: These areas must be clearly identified, and usually surround or adjoin the Core Areas. Buffer Zones may be used for cooperative activities compatible with sound ecological practices, including environmental education, recreation, ecotourism and applied and basic research.

Transition, or Cooperation, Zones: These areas may contain towns, farms, fisheries, and other human activities and are the areas where local communities, management agencies, scientists, non-governmental organizations, cultural groups, economic interests, and other stakeholders work together to manage and sustainably develop the area's resources.

ไม่แน่ใจว่า Hanifaru Bay จะถูกจัดให้เป็นพื้นที่ (zone) ไหน
ถ้าเป็น core area ผมว่าโอกาสที่จะจำกัดจำนวนนักดำน้ำมีความเป็นไปได้สูงแน่นอนครับ
