Note alder in foreground. Mile- square cutting unit, Maybeso Experimental Forest. Dense salmonberry brush, sometimes togeth- er with logging slash, was the second most com- mon surface condition on nonstocked plots. Salmonberry brush occurred on gently sloping alluvium at scattered locations but was most common on flat, well-drained Tonowek soil along Maybeso Creek on good sites subject to periodic high water table and recurring floods (fig. 15). Dense brush patches were often lo- cated near a good spruce and hemlock seed source. Tree seedlings appeared to be confined largely to raised microsites on or beside stumps, on rotten logs, or on hummocks. Leaders of spruce seedlings were often abraded by sur- rounding brush. Before the logging operation, these alluvial soils supported open stands of spruce and hem- lock with a dense understory of salmonberry, elderberry, thimbleberry, and devilsclub. Many of the original trees were stilt-rooted, having germinated on down logs or upturned roots. Being along the creek, the areas were near the periphery of high-lead settings where ground.
