conservation policies need to deliver on multiple criteria, including
genetic diversity, population viability and species richness as well as
ecosystem services. The challenge of integrating these may be addressed
by simulation modelling.
- We used four models (MetaConnect,
SPOMSIM, a community model and InVEST) to assess a variety of spatial
habitat patterns with two levels of total habitat cover and realised at
two spatial scales, exploring which landscape structures performed best
according to five different conservation criteria assessed for four
functional types of organisms (approximately representing trees,
butterflies, small mammals and birds).
- The results display both
synergies and trade-offs: population size and pollination services
generally benefitted more from fragmentation than did genetic
heterozygosity, and species richness more than allelic richness,
although the latter two varied considerably among the functional types.
single landscape performed best across all conservation criteria, but
averaging over criteria and functional types, overall performance
improved with greater levels of habitat cover and intermediate
fragmentation (or less fragmentation in cases with lower habitat cover).
- Policy implications.
Using four simulation models, we show that different conservation
objectives must be traded off in spatial conservation planning, and that
considering only a single taxon or criterion may result in suboptimal
choices when planning reserve networks. Nevertheless, heterogeneous
spatial patterns of habitat can provide reasonable compromises for
