Detection of critical densities associated with pinon-juniper woodland ecotones

The interfaces between piñon-juniper canopies and grasslands in the south-western USA present an opportunity to use the modern theory of spatial phase transitions as a formal characterization of ecotone structure. The theory requires an estimation of a critical value of tree cover at which the woodl...
