A new method was devised to model factors affecting the emergence of conifer seeds. For this, large monoliths of forest soil, including litter and one or two mineral horizons, were collected and used intact under greenhouse conditions. The monoliths were subjected to simulated fires, which yielded various depths of burn, and they were seeded with seeds of conifers. To model the effect of drought and shade the monoliths were subjected to various watering and shading regimes.
