From: Variation in irradiance, soil features and regeneration patterns in experimental forest canopy gaps
Mean values and standard deviation of variables per gap position (A, B, C and D) for the year 2004: gap position A - plots located along the gap edges with less sun exposure; gap position B - plots in the gap centres with the highest irradiance; gap position C - plots under the forest canopy, which correspond to the lowest ISFs and DSFs; gap position D - plots along the sun-exposed edges of the gaps. Variable descriptions: DSF direct site factor (%), ISF indirect site factor (%), ROCK surface covered by rocks (%), GRAVEL gravel content (%), O thickness of Of and Oh horizons (cm), A depth of A horizon (cm), B + E depth of B and E horizons (cm), M depth of mineral component of soil (sum of A and B + E horizons) (cm), VEGE ground vegetation cover (%), SM MAX maximum soil water content in 2003 and 2004 (%), SM MIN minimum soil water content in 2003 and 2004 (vol%), SM AVG average soil water content in 2003 and 2004 (vol%)
