Paper Mulch for Reforestation in Southwestern Oregon
Abstract:A survey was made in western Oregon to determine the effect of paper mulch on first-year survival of 2-0 Douglas-fir seedlings. Nine planting sites, representing three different climatic and topographic conditions, were selected. Two hundred and fifty seedlings with mulch and an equal number of seedlings without mulch on each planting site were marked in spring and their survival was checked in the middle and at the end of the growing season. The survey showed that: (1) Survival of seedlings was increased significantly by paper mulch on each planting site; (2) survival with mulch was up to five times higher than that of seedlings without mulch; (3) degree of success with mulch appeared to be related to amount of precipitation and time of application, but not to steepness of site; (4) paper lasted through the growing season, but began to disintegrate rapidly with the onset of fall rains.
