Planning reserves for ecosystem services
Ecosystem services and biodiversity map differently, so conservation plans face spatial tradeoffs.

500 ha units.
These features are allocated by “planning units,” which are the uniform spatial unit of analysis (500 ha in this analysis).
20 MARXAN runs.
In this analysis, we ran MARXAN 20 times for each service to ensure an even sampling of possible networks.
What they did
Mapped seven benefit functions across 11,272 planning units and built MARXAN conservation networks for a California ecoregion.
What they found
Services had distinct spatial patterns and low correlations; places like Salinas Valley scored high for pollination but not other services.
The limits
What it doesn't show
Does not field-test whether implementing a network delivers measured service gains.
