This study aimed to compile an iventory of remnant old growth trees that were planted along the border of homesteads as windbreaks, and to explore the conservation status of these old growth trees, Two survey sites in the southernmost part of Okinawa Prefecture, Japan, were selected. We found that the tree line at the north and east sides of the homes have been protected and were better conserved than the tree line at the south and west sides. The average tree density was approximately 0.8± 0.32 (SD) trees per meter for well-preserved tree belts. The conservation and maintenance of old growth trees within the homestead depends on natural and human factiors. Exposure to thyphoons and monssonal wionds are among the most important natural factors that contribute to tree damage. However, human factors are also important in terms of tree cutting or conservation. The resident’s awareness on tree conservation determined whether trees were preserved or felled.
