1. Survey Objectives |
|
 |
Nurtured by the ages, big trees and forests symbolize Japan. They provide habitat for animals and sublime scenic vistas. They furnish regional symbols and nourish the soul. They are an extremely important natural resource that must be preserved. The objective of this survey was to determine the state of big trees throughout the country. |
 |
2. Survey Content and Methods |
|
 |
The survey was conducted targeting, in principle, trees with a trunk girth of 3m or more at a height of about 1.3m from the ground. Species whose trunk girth tends to be less than 3m (camellia, spindle tree, etc.) were subject to the survey even if they did not reach the 3m mark. The 6th survey involved a follow-up study targeting big trees confirmed in the 4th survey, and a new study targeting big trees confirmed in subsequent surveys. A field survey was conducted with respect to the following items.
(1) General: Location, tree age, species, trunk girth, height, etc.
(2) Preservation: Preservation designation, etc.
(3) Ecology: Surrounding conditions, health, etc.
(4) Cultural Associations: Religious beliefs, tradition, legends, etc.

3. Survey Results |
|
 |
In the 4th survey, the trunk girth of 55,798 big trees across the country was measured and reported, including individual trees, forests and groves. Big trees were most commonly found in forests. In particular, groves preserved in shrine precincts were found to have retained a natural environment, although small in area, and played an important part as a habitat for big trees.
In the 6th survey, responses were received from 1,661 municipalities and members of the National Big Tree Club (response rate: 51%). According to the reports, 11,572 big trees were newly-identified, and 1,660 big trees were lost due to death or logging. Big trees subject to the survey totaled 64,479 nationwide. In the 6th survey, there were many reports from mountainous regions and isolated islands which had a low profile in the previous survey (4th survey). The nation$B<><%<>Big Tree Photographs)
