Overview

Understanding the impacts of land use/land cover (LULC) changes on ecological processes is essential for addressing biodiversity loss, habitat fragmentation, and climate change. This study analyzes the effects of LULC changes on habitat quality and landscape connectivity in İzmir, Turkey’s third-largest city, using the Integrated Valuation of Ecosystem Services and Trade-offs Habitat Quality (InVEST HQ) model, Conefor 2.6 connectivity analysis, and Circuitscape 4.0 resistance-based modeling. This study relies on Coordination of Information on the Environment (CORINE) Land Cover data from 1990 to 2018. Findings indicate that artificial surfaces increased by 82.5% (from 19,418 ha in 1990 to 35,443 ha in 2018), primarily replacing agricultural land (11,721 ha converted). Despite this expansion, high quality habitat areas remained relatively stable, though habitat fragmentation intensified, with the number of patches rising from 469 in 1990 to 606 in 2018, and the average patch size decreasing from 394.31 ha to 297.39 ha. Connectivity analysis highlighted Mount Nif and the Urla–Çeşme–Karaburun Peninsula as critical ecological corridors. However, resistance to movement increased, reducing the likelihood of connectivity-supporting corridors. These findings emphasize the importance of integrating spatial modeling approaches into urban planning and conservation strategies to mitigate future habitat loss and fragmentation.
