Rationale

Quercus hondae Makino, which distribution is restricted in southern parts of Kyushu and Shikoku, is designated as an endangered species (IB). In Miyazaki prefecture, southeastern Kyushu, this species usually appears in secondary (semi-natural) forests dominated by Castanopsis cuspidata Schottky. In this study, we aim to suggest a conservation strategy for Q. hondaeon the basis of forest ecology, tree ecophysiology, and forest genetics.

Project aims

  1. To clarify natural distribution and habitats
  2. To examine eco-physiological and reproduction trait
  3. To evaluate genetic diversity
  4. To suggest appropriate conservation strategy

Work plan (1999-2002)

To analyze of natural distribution, population structure and phytosociological characteristics
To determine the habitat
To evaluate tolerance to shade and moisture stresses
To evaluate genetic diversity and gene flow under topographic constraints
To evaluate reproductive traits
To estimate potential habitats based on topography map on GIS
To construct conservation strategy and field practices
