Appendix A. A table reporting the drainage size, hydrologic characteristics, vegetation structure, and soil respiration for 15 sites distributed across the Sycamore Creek catchment.
TABLE A1. Summary data for sites used in the spatially extensive survey of soil respiration. Where appropriate, values are averages (±SE). Symbols are as follows: CA = catchment area (km2), U = upland, R = riparian, EP = episodic, E = ephemeral, I = intermittent, and P = perennial. Plant cover data are from line transects; volume data are from 15 plants selected along transects at each site.
