Dataset for: An optimisation approach for designing wildlife corridors with ecological and spatial considerations

The fragmentation of wildlife habitats caused by anthropogenic activities
has reduced biodiversity and impaired key ecosystem functions. Wildlife
corridors play an important role in linking detached habitats. The optimal
design of such corridors considering spatial, ecological, and economic
factors is addressed in this paper. We present a novel graph-theoretic
optimisation approach and a mixed-integer linear programming model to
determine an optimal wildlife corridor connecting two given habitat
patches. The model maximises the total quality of the corridor and
satisfies pre-specified corridor width and length requirements under a
resource constraint. Compared to the corridor design models presented in
the literature, our model is conceptually simpler, and it is
computationally convenient. We applied the model to a real data set for
Eldorado National Forest in California, USA, involving 1,363 irregular
land parcels. The model can be extended to design multiple corridors that
connect two or more existing habitat patches.
