Pacific madrone will grow toward openings, leaning as much as 15 to 20 degrees. Pacific madrones in mixed-conifer forests provide a middle canopy story, an important element in forest structural diversity. The leaves can be used to test the temperature of pitch that is being used to waterproof canoes. * Important announcements and news An ideal plant for the small garden or as a lawn specimen, it has a neat, compact, upright growth habit, retaining its lower leafy branches close to the ground and casting little shade[245]. The bark is a rich source of tannin[46, 61, 82, 226], it is used medicinally[168]. Cruising and Harvesting Diameter at breast height and total height of Pacific madrone can be used in tables or equations to estimate total tree volume in cubic feet and sawlog volume. Pacific madrone is generally restricted to soils with good internal drainage; it will not tolerate poor soil drainage or flooding. Plumb and N.H. Pillsbury, tech. As with other fine-grain, hard woods such as birch or maple, surface scratching (cross-grain or swirls) during sanding can be a problem with Pacific madrone. There are few examples of growth and yield from managed stands. We are working on a subset of plants in the PFAF database identified as having the most potential for inclusion in such designs. Because of its high density, it should not be processed too fast (overfeed). Pacific madrone is a common associate in a variety of other major cover types in the region.
