1 Progressive strip clear cut system: A silvicultural system in which, clear felling is done in the form of strips which progress successively in one direction across the regeneration area. 2  The crop produced is even-aged considering each strip as a compartment.lear felling system. The clear felling system is a silvicultural system in which equal or equiprodcutive areas of mature crop are successively clear-felled in one operation to be regenerated most frequently, artificially but sometimes naturally also.
