- Intervention effect Oak mean height was affected by spacing only in the third and fourth years after establishment.
- Intervention effect Later spacing differences in oak growth and quality traits were small and insignificant.
- Observation Willow and aspen regeneration was abundant at lower oak planting densities.
- Mechanism At lower oak densities, interspecies competition from regeneration replaced intraspecies competition and explained the absent growth and quality response to spacing.
- Intervention effect Wider oak spacings were economically beneficial compared with traditional densities during the study period.
- Observation Competition from natural regeneration affecting oak height growth required extensive tending.
- Recommendation The authors expect more future tending, which might reduce the initial economic advantage of wider oak spacing.
- Recommendation The authors call for longer-term study of the economic efficiency of wider oak spacing.
