Since trees are the dominants here, it was necessary to increase the size of the quadrat to 10 meters on a side. This quadrat, therefore, equals in area 4 of those in other localities. A summary, as far as the dominants are concerned, is given (fig. 6): Clumps. Stems. Quercus agrifolia 6 6 Arbutus menziesii 2 8 ^Esculus californica 2 2 The specimens of Quercus and JEsculus are all single-stemmed individuals. Those of the latter species are of little importance, being but and cm. in diameter. The oaks range in diameter from to 36 cm., four being 10 cm. or larger. The eight Arbutus stems are in two clumps of large stump sprouts, a very common habit of the species. The diameters of the individual stems range from 10 cm. to 18 cm. The area is shaded and controlled by the.
