The development of 157 tanoak [Lithocarpus densiflorus(Hook. and Am.) Rehd.] and 130 Pacific madrone (Arbutus menziesiiPursh) sprout-clumps 1 to 6 yr after cutting or burning was studied on a range of sites in southwest Oregon. The width and area of sprout-clumps originating from trees ≥ 2-cm stem diameter at 1.4-m height of both species was related to the size of the parent stem and time since cutting (tanoak, r2= 0.77 and 0.75; Pacific madrone, r2= 0.84 and 0.83). The sprouting capacity of tanoak develops slowly, and 5 to 6 yr after cutting, sprout-clumps produced by small tanoak 40 to 50 yr old averaged only 37 cm in diameter. Prediction equations, along with stem-diameter distributions of these species in forest stands, can be used to estimate hardwood foliar cover up to 6 yr after cutting.

AbstractInsects were sampled in a Douglas-fir forest in California to evaluate differences among inexpensive survey methods. Sampling was done with sweep nets and with window, sticky, light, suspended cone, and two kinds of yellow pan traps. Also examined were effects of trap location in the given tree and the following tree species: Douglas-fir (Pseudotsuga menziesii Franco), canyon live oak (Quercus chrysolepis Liebm.), tanoak (Lithocarpus densiflorus Rehd.), Pacific madrone (Arbutus menziesii Pursh.), and big-leaf maple (Acer macrophyllum Pursh.). Relative abundance and faunistic similarity of the 9662 insects caught varied greatly by trap type and little by tree species or trap location. Family-level taxonomic richness differed among the diverse trap types, tree species, and trap locations.

Broadleaf species such as tanoak [Lithocarpus densiflorus (Hook. & Arn.) Rend.] and pacific madrone (Arbutus menziezii Pursh) reduced conifer growth on previously logged or burned areas of the northern California and southwest Oregon coast range. Cut-surface applications of 2,4-D [(2,4-dichlorophenoxy)acetic acid], 2,4,5-T [(2,4,5-trichlorophenoxy)acetic acid], and picloram (4-amino-3,5,6-trichloropicolinic acid) into tanoak and pacific madrone growing as overstory to Douglas fir [Pseudotsuga menziesii (Mirb.) Franco] were found to provide acceptable control for 10 years following application. Increment cores obtained from Douglas fir in treated and non-treated plots revealed substantial stem enlargement as a result of tanoak and pacific madrone control.

Diameter Distributions

Abstract Crown size and stem diameters were measured on a total of 908 sprout clumps of tanoak (Lithocarpus densiflorus), Pacific madrone (Arbutus menziesii), and giant chinkapin (Castanopsis chrysophylla). The clumps, age 1 to 16 years, were located at 23 sites in southwestern Oregon and 20 sites in northwestern California. Regression equations were developed for predicting individual-clump crown size and stem-diameter distributions of dominant sprouts from the total basal area (dm² at 1.37 m) in stems of the parent tree (PBA) and number of growing seasons since burning (AGE). Variables of PBA, AGE, and species in combination accounted for over 75% of the total variation in hardwood crown width and height and for 62% of the variation in sprout number. Variables describing site characteristics and competing vegetation abundance did not explain more than 2% of additional variation in hardwood crown size or sprout diameter distribution. On the basis of the Kolmogorov-Smirnoff test (α = 0.05), the Weibull function adequately described the reverse J-shaped distribution of stem diameters for individual sprout clumps. The goodness of fit for each of the predictive models for tanoak and madrone was verified with independent data. West. J. Appl. For. 7(4):103-108.

Abstract Broadcast, directed, and stem injection herbicide techniques were applied to 3- to 8-year-old black oak (Quercus kelloggii) and 3-year-old tanoak (Lithocarpus densiflorus) clumps (directed applications only). Broadcast applications of imazapyr at all rates to black oak and directed applications of imazapyr to tanoak performed better with the addition of an adjuvant compared to treatments without the adjuvant. However, even with an adjuvant, broadcast treatments of imazapyr at or below 560 g acid equivalent (ae/ha) only suppressed black oak growth and did not provide long-term control. Directed applications of imazapyr gave excellent control of both black oak (0.43–2.17% ae plus Sylgard) and tanoak (0.14–1.13% ae plus Hasten) clumps. Imazapyr was more effective than basal bark treatments with triclopyr (8.9% ae), and tank-mixing imazapyr with glyphosate did not improve the level of control. Stem injection treatment of black oak trees or clumps with imazapyr was very effective with nearly all rates and hack intervals, but late summer or fall applications gave greater suppression of basal re-sprouts compared to spring and early summer treatments. These results demonstrate that imazapyr is a very effective and versatile tool for the control of black oak and tanoak clumps and black oak trees. West. J. Appl. For. 19(4):268–276.
