Evolutionary and genetic knowledge is increasingly being valued in conservation theory, but is rarely considered in conservation planning and policy. Here, we integrate phylogenetic diversity (PD) with spatial reserve prioritization to evaluate how well the existing reserve system in Victoria, Australia captures the evolutionary lineages of eucalypts, which dominate forest canopies across the s...

Protected areas have mixed success in preserving forest, and it is important for conservationists ...

containing protected areas (i.e., national parks, national monuments, wildlife refuges, and wilderness areas) are growing more rapidly than counties without such areas (Rasker et al. 2004).
