Experimental design
To assess how shade, water availability and plant-plant interactions
influence annual plant fitness, we manipulated water availability and
interaction neighbourhoods in four open (0-12% canopy closure) and four
shaded (58-100% canopy closure) blocks across the reserve. We measured
demographic responses of nine common annual plant species that represent
a variety of annual plant strategies (Table 1).

by family and their origin (native or exotic).
