Description: On many thousands of acres of cut-over timber lands in California, brush of various species has gained such control of the soil that the success of natural reproduction is problematical. This condition is particularly serious in the high site quality sugar pine-white fir and sugar pine-ponderosa pine types, where the maintenance of sugar pine in the stands is a silvicultural objective. This study was designed to determine whether clearing the brush from unstocked areas during a good sugar pine seed year would foster natural regeneration of sugar pine and to compare the effectiveness of three methods of establishing reproduction: natural seeding, seed spotting, and planting on the cleared areas.
