Abstract Many native forage plants in the South are low quality, poor producers, and unpalatable to cattle. Replacement of these plants with more desirable species would improve the forage resource. One approach is to seed grasses during site preparation when regenerating southern pines. Following site preparation by shearing and strip-disking, Pensacola bahiagrass (Paspalum notatum) was seeded at 15 pounds per acre in the spring and longleaf pine (Pinus palustris) was row-seeded on 12-foot centers in December of the next year. The bahiagrass became established among the residual native plants and was heavily utilized by cattle grazing yearlong. A light application of fertilizer after 3 years tripled bahiagrass yields the first year and doubled it the next year compared to unfertilized plots. Fertilizer improved some nutritional qualities of bahiagrass but digestibility was lowered. Longleaf pine seedlings came out of the grass stage more rapidly and were 50% taller at age 9 with grazing than without it; and in spite of heavier mortality with grazing (36% vs. 21%), stocking was 967 trees per acre at age 11.

Survival And Growth

Abstract Benomyl applied to roots of longleaf pine (Pinus palustris Mill.) seedlings at planting significantly reduced brown-spot disease and increased survival, root collar diameter, and early height growth on two sites in Mississippi. Seedlings with half or more of all ectomycorrhizae formed by Pisolithus tinctorius (Pers.) Coker and Couch in the nursery had significantly better survival and growth; Pisolithus ectomycorrhizae did not appreciably affect brown-spot disease. The benefits of benomyl and Pisolithus ectomycorrhizae were most obvious when combined. More than 75 percent of seedlings treated with benomyl and with more than half of all ectomycorrhizae formed by Pisolithus initiated height growth after 3 years. Forty-seven percent of seedlings with only Thelephora terrestris ectomycorrhizae and without benomyl exhibited height growth. The combined use of benomyl to control brown-spot disease and Pisolithus ectomycorrhizae to stimulate early height growth may overcome the major handicaps that have limited artificial regeneration of longleaf pine in the South.

Abstract After seven annual May burns, grass-stage longleaf pine (Pinus palustris Mill.) seedling survival averaged 71 percent, significantly higher than survival on a biennial May burn, an annual or biennial March burn, or an unburned control. Seedling height growth on the annual May burn was no better than that on the biennial May burn, but both May burns significantly exceeded the other treatments in height growth. The annual May burn also provided greatest survival and growth for longleaf seedlings that had begun height growth before the study began.

An experiment was established in 1961 to determine the influence of bearmat (Chamaebatia foliolosa Benth.) competition on ponderosa pine (Pinus ponderosa Laws.) survival and growth. Ponderosa pine seedlings were planted in bearmat which was: (A) untreated, (B) sprayed with a mixture of 2,4-D [(2,4-dichlorophenoxy)acetic acid] and 2,4,5-T [(2,4,5-trichlorophenoxy)acetic acid], and (C) eliminated by a combination of herbicide, clipping sprouts, and trenching to prevent root and rhizome invasion. Ponderosa pine survival after 19 yr averaged 9%, 66%, and 90%, respectively, for the three treatments. Tree height after 19 yr averaged 1.6, 1.9, and 5.7 m for treatments A, B, and C, respectively. Soil moisture use was initially less on the herbicide-treated than on the untreated plots, but bearmat quickly sprouted after application to compete with the pine seedlings for moisture. After 19 yr the bearmat was more dense and appeared to be more vigorous on the sprayed plots than on those receiving no treatment. We estimate that 75% reduction in net wood production could result after 50 yr on this site from bearmat competition.

Survival And Growth

Abstract The purpose of this article was to determine whether natural regeneration or planted seedlings should be used in group-selection openings. The answer depends on the survival and growth rate of both types of seedlings, and that could depend on the size of the openings and the effect of trees on their edge. In this side-by-side study, the natural pine seedlings originated from the 1988 seed crop and the 1–0 nursery-grown seedlings were outplanted in spring 1989. Openings ranged from 0.01 to 0.65 ha. The plant community consisted of many species of shrubs, forbs, and grasses with manzanita having the highest density and greatest development. After 9 years, manzanita had an average density of 13,870 plants/ha, 2,050 m2/ha of foliar cover, and was 125 cm tall. From 1990 to 1997, planted ponderosa pine seedlings were taller (P < 0.05) than natural seedlings, and from 1995 to 1997, mean stem diameter at 30 cm of planted seedlings was larger than natural counterparts (P < 0.05). Development for 1 year in the nursery apparently gave the planted seedlings a growth advantage over the natural seedlings. For natural seedlings, distance from opening edge had little effect on pine height or diameter growth regardless of opening size. Planted seedlings, however, appeared to increase in height and diameter growth with both opening size and distance from edge.

Abstract Orchard stands and savannahs are forest openings that failed to regenerate after turn-of-the-century logging and have been dominated by dense herbaceous plant growth for 50 or more years. The effectiveness of herbicide application, mechanical site preparation, and fertilization on survival and growth of five species of seedlings was tested over a 6-year period. Neither site preparation nor fertilization significantly increased survival of any species above the control during the first 2 years after planting. Residues of picloram, one of the herbicides used during site preparation, reduced survival of all species, except white ash, below that of the control. Fertilization reduced survival of all species. Black cherry was the only species that grew better as a result of the treatments. Weed removal significantly increased black cherry seedling growth, but much of this increased growth was in branches, rather than the terminal shoot. Mechanical site preparation plus herbicide did not increase growth of black cherry seedlings above that of herbicide alone during the first 2 years and had the disadvantage of stimulating reinvasion by grass. Deer which penetrated the protective fence interfered with evaluation of growth after the second year. North J. Appl. For. 2:22-26, Mar. 1985.

Survival And Growth

Abstract This paper is the first general review of the affects of container volume on the survival and growth of containerized white spruce, black spruce, and jack pine seedlings. The review shows that the literature on this topic is fragmentary and inconsistent. Seedling growth in the greenhouse production phase has been more completely quantified than subsequent establishment and growth after out-planting in the field. In the greenhouse production phase, seedling growth increased from 72 to 360% when the container volume was tripled in size. After outplanting in the field, seedling growth trends were more variable. Seedling height growth increased from 34 to 84% when container volume was tripled in size. Seedling survival was more difficult to assess because of limited data. Only white spruce showed a 10% increase in survival with an increase in container volume. The indications from this literature review suggest that nursery managers and practicing foresters should become more aware of the limitations imposed on seedling survival and growth due to container volume. To maintain optional survival and growth for white spruce, black spruce and jack pine, the container volume should range from 90 to 120 cm3. North. J. Appl. For. 5:185-189, Sept. 1988.

Abstract Seedlings of loblolly and longleaf pine lifted in December, January, and February were treated with either benomyl or ridomil before cold storage. Along with an untreated control, they were planted after cold storage of less than 1 wk, 3 wk, and 6 wk. Survival was measured in mid-June after planting, and after 1 and 4 yr in the field. Total height was measured after 4 yr. The fungicide application increased survival of both species lifted in December or February and was beneficial to longleaf pine seedlings regardless of storage duration. Fungicide-treated longleaf pine seedlings had greater mean 4 yr height than the controls, but fungicides did not affect the height of loblolly pine. South. J. Appl. For. 20(1): 5-9.

The Cost

Abstract The cost of planting southern pine seedlings is influenced by intensity of site preparation, number of parcels of land included in the planting contract, site topography, whether the site is bedded, and type of planting method. Industrial foresters should carefully examine anticipated benefits before intensifying site preparation, especially before using bedding or specifying machine planting.
