A new cost-distance model for human accessibility and an evaluation of accessibility bias in permanent vegetation plots in Great Smoky Mountains National Park, USA
Jobe RT and White PS. 2009. A new cost-distance model for human accessibility and an evaluation of accessibility bias in permanent vegetation plots in Great Smoky Mountains National Park, USA. Journal of Vegetation Science. 20:1099-1109
This study concerns how much accessibility bias is present in the vegetation monitoring plots accumulated over the last three decades in Great Smoky Mountains National Park. Results show the bias in plot locations suggests using a least-cost model to test for bias in cases in which human accessibility is confounded with other sources of ecosystem variation.
