4. 1. Background
Ⅰ.Introduction
Biodiversity in forest edge is high because this area interacts with diverse ecosystems.
Particularly, ecotone connected to agriculture or grassland is important for many forest species requiring ‘open area’ as the part of habitat.
Forest edge could be buffer area of forest core.
However, development pressure is high especially at forest edge.
In many development projects, considering the conservation value of forest edge is insufficient.
Development of forest edge could harm not only itself but also diverse ecosystems interact with it.
This core of forest

5. 2. Objectives
Ⅰ.Introduction
The objective of this study is to offer the scientific basis for conserving critical area of forest edge against the development pressure.
For this purpose,
-First, habitat suitability map is conducted.
-Second, the critical ecotone is extracted.
-Finally, comprising the ecotone in the habitat suitability
map, conservation value of forest edge is assessed.

Ⅱ.Methods
Study area : SeongNam City, GyeongGi-do, Korea
Administrative district
Planned city for the population decentralization in the Metropolitan area.
Since the year 1989, this city have been developed dramatically
Research and Survey of species shoud be based on watershed. But in this paper, point data of birds is constructed on administrative district.
So, I select Seong Nam City as my study area. The portion of green and stream is over than 80 percent in SeongNam. So species inhabit SeongNam are very diverse.

22. Ⅳ. Conclusions & Discussions

23. 1. Conclusions & discussions
Based on seven factors, habitat suitability map of target species is conducted
-Applying Focal species conservation to forest edge is distinguished point.
-High value of this map is distributed in forest edge.
-This approach offer simple tool to identify habitat area of target species.
The effectiveness of habitat suitability map is evaluated.
-The 5,6,7 grades of habitat suitability map indicate high representation for
other species of Hole nesting and canopy foraging guild.
-It should be evaluated whether it could be representative of the
other forest edge species

24. 1. Conclusions & discussions
The length of forest-agriculture ecotone is comprised in conservation value assessment.
-Only the grids where ecotone length longer than 200m(grid size) are
extracted in this study.
-However classifying the ecotone length as the degree of interaction is
required in future research.
Additional conservation area could be established in forest edge based on this result.
-the result of this study could be supplementary data for existing
conservation area such as DGN or Ecological Naturalness.
