Appendix A. Description of the study site vegetation in Dry Chaco woodland (Argentina, lat-lon: -33.5; -66.5).

Table A1. Relative frequency of species present in transects grouped by layers (herbaceous, shrub and tree) according to their height based on Canfield lines (three 36-meter lines for each layer). Other species present in the study site, but not intercepted by transects, are the trees Geoffroea decorticans and Bulnesia retama.
