Ⅰ. Introduction


Establishing a conservation area by habitat and landscape matrix analysis

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.

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

  • Selection Conditions

  • 1: Almost forest area within administrative boundary is under forest edge.

  • 2: Existing conservation area is limited core area of forest.

  • 3: The gradation of urban-agriculture-forest is represented well.

  • 4: There are critical habitats of 55 bird species in this gradation.

Ⅲ.Results

Forest-agriculture ecotone

  • Extracting forest-agriculture ecotone

  • Mapping the length of the ecotone by 200mgrid

  • The longer length of ecotone is, the more interaction between ecosystems is caused.

  • The forest patches larger than 2ha(MVA) are comprised in this analysis

Ⅳ. Conclusions & Discussions


Establishing a conservation area by habitat and landscape matrix analysis

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


Establishing a conservation area by habitat and landscape matrix analysis

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.
