Table 2. Results of a logistic regression model, estimating how the probability of finding O. europaea depends on ontogenetic stage (adults [reference level], sapling, seedling) and environmental conditions and human disturbance (logging intensity) in Hugumburda dry Afromontane forest in northern Ethiopia.

The table shows parameter estimates and associated standard errors for a binary generalized linear model, where the response had two possible outcomes Y (empirical observation) = 1 and Y (simulated observation) = 0. Simulated observations were generated by random relocations of the empirical observations of O. europaea in 70 sample plots. Figures in bold are statistically significant at P < 0.05.
