“…Moreover, conservation planning for species with different requirements can be effective if several ecoprofiles are implemented. This conservation planning has been applied in eco-network evaluation and planning (McHugh and Thompson, 2011). Least-cost model has been developed to simulate the functional connectivity route quantitatively (Vuilleumier and Prelaz-Droux, 2002;Adriaensen et al, 2003).…”

The protecting requirements and functional connectivity of species in isolated habitat patches are crucial factors of eco-network planning. This study aimed to improve the method of eco-network planning for species conservation. Ecoprofiling was used to group the species by similar behavior types, namely, choice of ecosystem, area requirement, and short distance dispersal abilities. A least-cost model was used to simulate the optimal corridor location to maintain functional connectivity. A combination of ecoprofile and least-cost model was hired to develop an eco-network that promoted species conservation. A case study was also conducted in Beijing, China. In addition to the required ecosystem, habitat area is an important parameter for habitat extraction. Habitat area can remove noise habitat patches because of lacking area. Short-distance dispersal can be used to identify corridor requirements and avoid unnecessary building requirements. Species with various dispersal abilities exhibit significant differences in terms of corridor length and location requirement. Habitat isolation is the main threat for weakly mobile species, and habitat loss is the major risk of mobile species protection. Different species groups also exhibit distinct landscape pattern demands for an eco-network, and the eco-network planning based on specific species can not protect other species. We proposed that a combination of ecoprofile and least-cost model improved the efficiency of species conservation by eco-network planning.

“…The term spatial ecological networks appeared initially in Europe as part of nature conservation policy and is broadly defined as a network composed of ecological components, e.g. core areas, ecological corridors, and buffer zones (Jongman et al 2004;McHugh and Thompson 2011). Greenways can be viewed as networks designed and managed for ecological, recreational, historical, aesthetic and cultural purposes.…”

Context Ecological networks are systems of interconnected components that support biodiversity, ecological processes and ecosystem services. Such structures play a crucial role for nature conservation and people well-being in anthropogenic landscapes. Assessing connectivity by using efficient models and metrics is a sine qua non condition to preserve and improve appropriately these ecological networks. Objectives This study aims to present a novel methodological approach to assess and model connectivity for species conservation (Bufo calamita; the natterjack toad) and human recreation in the city. Methods The study used a combination least cost and circuit models to identify priority corridors in the City of Liège, Belgium. Green areas, habitats and relevant movement parameters were derived based on existing studies around (i) the occurrence, ecology and biology of the natterjack toad and (ii) human behavioural studies on urban pedestrians. Combining the two models allowed the assessment of connectivity for both species via two different metrics visualised using priority corridors on maps. Results The connectivity assessments identified lack of connectivity as the potential route to extinction of natterjack toads at one of the source sites. Conclusions This study provides examples of how combining least cost and circuit models can contribute to the improvement of urban ecological networks and demonstrates the usefulness of such models for nature conservation and urban planning.

“…Opdam et al [17] proposed a spatial indexing approach to analyze the conservation potential of landscapes for different species. McHugh and Thompson [18] studied an ecological network model for conservation planning using eco-profiles of species. Ferretti and Pomarico proposed an effective tool for spatial planning by integrating GIS with multi-criteria analysis [19].…”

The determination of protected area (PA) boundaries and the level of restrictions is very important for sustainable conservation, and such decisions must involve biodiversity data and assessment. In a PA, the consensus of the government and the locals is crucial to ensure protection–use balance. The PA restrictions constrain legal human activities, and the boundary determination and the restrictions should be based on various scientific analyses to achieve consensus. In this study, a GIS-based approach is proposed to utilize the biodiversity data for efficient conservation and land use planning in Kas-Kekova PA, which is among the most important PAs in Turkey. Spatial analysis methods, i.e., kernel density estimation, natural breaks classification and integrated density index, were performed for the assessment of the habitat networks using georeferenced biodiversity datasets, and the results were evaluated with respect to the actual land use data and the land ownership pattern. The developed spatial analysis approach is efficient to produce the conservation base maps required for regional land use planning, for defining sustainable conservation strategies, and to provide a widely accepted base for land use planning and biodiversity monitoring in the PA; although careful investigations and expert opinions are still required for data deficient areas.
