Appendix A. Tables showing mean post-treatment abundances of the twenty most abundant arthropod taxa on Douglas-fir by functional group in each of the six green-tree retention treatments (Table A1) , on Douglas-fir by functional group on edge and interior trees in aggregated retention treatments (Table A2), on vine maple by functional group in each of the six green-tree retention treatments (Table A3) , and on vine maple by functional group on edge and interior trees in aggregated retention treatments (Table A4).

TABLE A1. Mean (SE) post-treatment (1999–2000) abundances (no./kg plant material) of the 20 most abundant arthropod taxa on Douglas-fir by functional group (in bold), in each of the six green-tree retention treatments.
