Table 1. The proportion of species pairs significantly departed from Heterogeneous Poisson model and the proportion of no fine-scale species interactions cross life forms.

	All species	Arbor	Shrub	Arbor-Shrub	Deciduous	Evergreen	Deciduous - Evergreen
Total pairs	2550	930	380	1240	870	420	1260
Proportion of no effect	52.8%	34.0%	81.6%	58.1%	49.1%	56.9%	54.0%
Proportion of attraction	27.8%	49.2%	11.6%	16.7%	28.8%	24.8%	28.1%
Proportion of repulsion	19.4%	16.7%	6.8%	25.2%	22.1%	18.3%	17.9%
Proportion of significant pairs	47.2%	66.0%	18.4%	41.9%	50.9%	43.1%	46.0%

Goodness-of-Fit tests were used to test the overall fit of the Heterogeneous Poisson model over 0−30 m distance interval with the 0.05 error rate under 199 simulations; Arbor-shrub indicates the fine-scale species interaction between arbor species and shrub species; Deciduous-Evergreen indicates the fine-scale species interactions between deciduous species and evergreen species.
