BARK MULCH TRAILS SUMMARY STATUS REPORT
This report summarizes a two phase project initiated by The Soil Conservation Service to establish a series of bark mulch trails in the Pacific Northwest. The project had two objectives; to develop a beneficial use for bark, which has been a waste product of the lumber industry; and to find an alternative to conventional mulches due to the increasing cost of and occasional shortages of grain straw and grass hay mulches. Several conclusions and recommendations have been drawn from this study: for seedling survival, the most desirable depth for bark mulch is approximately 1/4 inch; seedling survival was essentiallty the same for bark mulched and straw mulched areas; Newport, Kentucky bluegrass is well suited to the Pacific Northwest; no legume seedlings were found; none of the seedlings produced sufficient ground cover during the first year to effectively control erosion; standard mulch blowing equipment, without modification, applies the bark well, but it is unsatifactory for use because of feeding problems and flying chips; and a flap to control the flying chips could be installed on the feeders of the mulch blower to allow application of smaller quantities for test plot purposes.
