established (numbered 4-8). Plots 4-6 were located on three, 0.64 hectare "framework species"
plantations established by the Forest Restoration Research Unit (FORRU) in June of 1998 (see
FORRU, 1998; Elliott et al., 2000 for additional site description and planting methods). Most of the
29 species of planted trees were between 0.5 and 2.5 meters tall when our perches, traps, etc. were
installed in June 1999. The ground flora of all plots was mostly herbs particularly Pteridium
aquilinum and composites, e.g. Eupatorium sp. The percent composition of these species changed
seasonally, and as a result of weeding for plantation maintenance. Planted plots were weeded every
four to six weeks in the rainy season (June - October). (Our observations also suggested that weeding
reduced the density and species richness of birds [R. Scott and S. Elliott, unpubl. Data], see Results).
