What is it about?
The early assessment of post-fire forest regeneration should be based on reliable and objective methods such as plot-count sampling. The relative efficiency method can be easily used to devise the best plot size and shape within such a sampling frame. Early regeneration of burned Aleppo pine stands is best assessed by plots with an area of 16 m2, that is four times wider than the most commonly used one. Rectangular plots (8m x 2m) are more efficient and practical than square plots (4m x 4m) for measurements in the field

Why is it important?
Early regeneration of Aleppo pine proved to be best assessed by 8m x 2m plots, i.e. by a plot size four times wider than the most commonly used one (2m x 2m). The need for such wide plots depends upon the typical spatial arrangement of the seedlings whose clustering is associated with the presence of seed bearing trees.
Perspectives
It is necessary to know the regeneration status of burned Aleppo pine stands to make decisions for cutting a burned stand, (re)planting insufficiently stocked areas, and eventual thinning woody species in competition with Aleppo pine. It is crucial to devise suitable methods of postfire regeneration assessment. This experimental study shows that in the environment investigated the early postfire regeneration of Aleppo pine is assessed best by a plot area four times wider than the one most commonly used.
