Quadratic polynomial fitted to each treatment with a coefficient of determination (r2) and significance level (***  P < 0.001). PF  primary unharvested forests, AR  aggregated retention, DRI  dispersed retention under the influence of AR, DR  dispersed retention without influence of AR. Each value represents the average number of seeds per year (million ha−1 yr−1) versus its corresponding viability (%) per treatment
