From: Responses in Bird Communities to Wildland Fires in Southern California
Least squares means for the most abundant bird species before and the most abundant after the fire (some remained the same), within each vegetation type at both elevations from point counts in San Diego County, California. The estimate (plus and minus one standard error displayed) is the net change in the average relative abundance (number of individuals per minute) for each. *** P < 0.001; ** P < 0.01; * P < 0.10 for individual species. Δ = the bird community structure differed significantly between non-razed and razed samples within the vegetation type at the reported elevation. Tests for changes in the relative abundance of species were only performed where there was a significant change in the community structure as indicated by the ANOSIM results. CHAP = chaparral, CSS = coastal sage scrub, GRASS = grassland. Refer to Appendix II for bird species code explanations.
