Estimating Changes in Habitat Quality through Land-Use Predictions: Case Study of Roe Deer (Capreolus pygargus tianschanicus) in Jeju Island

Abstract

This study predicts future land-use changes and the resulting changes in habitat quality, suggesting a method for establishing land-use management to ensure sustainable wildlife habitats. The conservation effects were verified in terms of wild animal habitat quality according to the designation of protected areas. Land-use change until 2050 was predicted using the Dyna-Conversion of Land Use Change and its effects (Dyna-CLUE) model for Jeju Island, Korea, and the change in the quality of roe deer habitats was predicted using the Integrated Valuation and Environmental Services and Tradeoffs (InVEST) model. Results indicate that, compared to 2030, urbanized area increased by 42.55 km2, farmland decreased by 81.36 km2, and natural area increased by 38.82 km2 by 2050. The average habitat quality on Jeju Island was predicted to decrease from 0.306 in 2030 to 0.303 in 2050. The average habitat quality ranged from 0.477 in 2030 to 0.476 in 2050 in protected areas and 0.281 in 2030 to 0.278 in 2050 outside protected areas. Habitat quality in protected areas was relatively high, and its reduction was limited. Areas with lower habitat quality need approaches such as expanding greenery and improving its quality. By establishing appropriate land-use plans by predicting habitat quality, wildlife habitats can be better maintained and protected, which is a primary goal of green infrastructure.

Comparative Mitogenomic Analysis Reveals Gene and Intron Dynamics in Rubiaceae and Intra-Specific Diversification in Damnacanthus indicus

“…The herbivory was pointed out as a major constraint of leaf and spine growth in D. indicus [67]. There is a different herbivore composition between Jeju Island and Kyushu [68,69]. The possible connection between change of ploidy level and phenotype [12] cannot also be ruled out.…”

InVEST model analysis of the impacts of land use change on landscape pattern and habitat quality in the Xiaolangdi Reservoir area of the Yellow River basin, China

“…Hence, the relationship between habitat quality and sources of threats to biodiversity can be established to explore the influence of threat sources on habitat quality (Sharp et al, 2018). Model assessment depends on the proximity of habitats to land used for human activities and the intensity of land use (Lee & Jeon, 2020), which indicate the influence of human activities on the surrounding environment. The more intense the human activities are, the greater the pressure on habitats and the lower the biodiversity level (Li et al, 2021).…”

Response of Spatio-Temporal Differentiation Characteristics of Habitat Quality to Land Surface Temperature in a Fast Urbanized City

“…Based on the basic situation of the study area, the InVEST User's Guide and previous research results [32,[40][41][42][43], we defined paddy field, dry land, built-up land, rural residential areas, and other construction land (quarries, mines, traffic land, etc.) as threat sources, and assigned values to the sensitivity of each habitat to threat factors (Tables 1 and 2).…”
