Abstract In the lower Atchafalaya Basin, water tupelo (Nyssa aquatica L.) trees were cut in May and November at three stump heights to study coppice regeneration. Sprouting was extremely good after one growing season, and live sprouts grew well through the third and fourth seasons. However, some stumps began to deteriorate and sprouts die after the second growing season. After six years, only 9 percent of the stumps cut in May and 18 percent of those cut in November had live sprouts.

Abstract Cuttings of eastern cottonwood (Populus deltoides) and seedlings of sweetgum (Liquidambar styraciflua), water tupelo (Nyssa aquatica), American sycamore (Platanus occidentalis), and green ash (Fraxinus pennsylvanica) were planted on a slackwater clay (Vertic Haplaquept) in western Mississippi in two consecutive years and inundated soon after foliation. During each of the two years, survival following flooding was consistently high for water tupelo, green ash, and sycamore, low for cottonwood, and intermediate for sweetgum. With the exception of green ash, however, all species lost their leaves and died back to the root collar during flooding. Thus trees, other than ash, that were living at the end of the growing season had originated from root collar sprouts.

Abstract The volume of sound wood in red oaks dead following gypsy moth defoliation (biotically killed trees) and in mechanically girdled control trees decreased significantly as time after death increased. Bark retention, site quality, and method of death were correlated with the volume ofwood degraded. Three growing seasons after death, biotically killed trees that retained their bark had greater volumes of degraded wood than those that shed their bark. Trees on oak site class 1 had greater volumes of degraded wood than those on oak site class 2. Wood of girdled trees deterioratedfaster than that of biotically killed trees. By the end of the third growing season after death, 19% of the gross merchantable volume and 21% of the board foot volume of biotically killed trees had been degraded. In a separate population of biotically killed trees, 44% of the trees had beenwind-thrown seven growing seasons after death. Based on these studies, salvage operations for most timber uses should be completed within 2 years after tree death. South. J. Appl. For. 13(3):139-145.

Abstract Two water tupelo (Nyssa aquatica L.) stands in the Mobile Delta of Alabama were selected to test the hypothesis that mechanized felling does not reduce establishment and growth of natural water tupelo regeneration relative to traditional tree felling with chainsaws. To test the hypothesis, we established six, 2 ac treatment plots in each of two blocks on each of two sites, and randomly assigned plots to either mechanical tree felling with a tracked, swing feller or chainsaw felling. Each site was clearcut in Fall, 1992, and merchantable boles were removed by helicopter. Establishment and growth of regeneration was assessed prior to harvest and annually for 3 yr after harvest in five, 0.01 ac measurement plots located in each treatment plot. Stand harvesting promoted establishment of water tupelo seedlings such that 3 yr after treatment we recorded over 270/ac on each site regardless of felling method. Seedling height increased at a steady rate and averaged about 39 in. tall after three growing seasons. Woody competition also responded to the harvest, outnumbering water tupelo seedlings 3 yr after treatment by as much as seven to one on Site 2. Water tupelo stump sprouts developing from chainsaw felling grew well and averaged about 13.5 ft tall after three growing seasons. However, mechanical felling reduced water tupelo stump sprouting by 50% leading to a lower density of sprout clumps in mechanically felled plots (P = 0.0253). Our results indicated that mechanical felling techniques used in this study may adversely impact regeneration of water tupelo swamps where coppice is a desirable form of reproduction. South. J. Appl.

Abstract Two vegetation management methods, paper mulching and spot-spraying with glyphosate, were combined with a root-dipping treatment, Terra Sorb®, to test effects on seedling survival and height growth on a harsh site in Oregon. Survival of Douglas-fir (Pseudotsuga menziesii) seedlings was significantly higher after the third growing season when competing vegetation had been controlled with mulch or glyphosate during the first two growing seasons. Seedlings retreated with paper mulch and glyphosate before the second growing season had 36 and 25% higher survival than those that were not retreated. None of the seedlings was retreated before the third season; after this season, survival of seedlings treated twice with glyphosate was 26, 23, and 21% higher than seedlings receiving one glyphosate treatment and one or two mulch applications, respectively. There were no differences in seedling height growth among treatments. Rootdipping with Terra Sorb® did not influence survival or growth. West. J. Appl. For. 1:108-111 Oct. 86.

Several kinds of seedbed mulch were used in an experiment to study frost heaving of white spruce (Picea glauca (Moench) Voss) in a nursery. Treatments consisted of silica gravel (of three sizes), hardwood sawdust, vermiculite, shredded sphagnum, mixed silica and sphagnum, and rye straw (the regular nursery mulch). These were applied to beds sown in the fall of 1958, 1959 and I960. Shading of beds during the winter between the first and second growing seasons was also examined.During the first growing season, several counts were made of the number of trees and weeds. At the beginning of the second growing season a count was made of the trees heaved and the residual stand. At the beginning of the third growing season, samples were taken for laboratory measurements of top length, root length, stem diameter, oven-dry weight and top-root ratio.The sawdust mulch was superior in most respects. It permitted the highest germination and survival, better prevention of heaving than rye straw, and better weed control than rye straw. Although the sawdust mulch treatment produced small and poorly balanced trees this was believed due chiefly to high bed density, and compared favourably with the rye straw. The use of hardwood sawdust as a mulch offered considerable advantage over the presently used rye-straw.Heaving was found to be a minor cause of mortality over the three year period examined. Shading of the beds offered no advantage in reducing this loss.

Abstract Shade-tolerant Engelmann spruce (Picea engelmannii) is a difficult species to reforest successfully in the high-elevation spruce-fir forests of the Rocky Mountains. This study investigated the use of plastic tree shelters as a form of shade protection and a means to improve the growth and survival of planted Engelmann spruce seedlings in southwest Colorado. A total of 1500 seedlings were planted into a 48 ha clearcut site at an average elevation of 3273 m. Treatments included four different colors of tree shelters and a control where seedlings were planted using the traditional shading method. This consisted of shading the seedlings using logging slash, stumps, and vegetation within the site. After two growing seasons, survival was 58% for the control treatment and ranged from 95 to 99% in the lighter three shelter color treatments. The darkest shelter color resulted in 95% mortality after the first growing season. Both height and diameter growth of surviving seedlings were significantly greater in the lightest two shelter color treatments as compared to the control treatment. These results indicate that tree shelters may provide an effective method of improving high-elevation Engelmann spruce reforestation programs. West. J. Appl. For. 16(3):114–120.

The effects of a preseeding application of the nematicide carbofuran (2,3-dihydro-2,2-dimethyl-7-benzofuranyl methylcarbamate) and the fungicide benomyl (methyl-1-(butylcarbamoyl)-2-benzimidazole carbamate), alone and in combination, on birdsfoot trefoil (Lotus corniculatus L.) were determined in the field. The nematicide and fungicide + nematicide treatments controlled root lesion nematodes (Pratylenchus spp.) in soil and roots for two growing seasons and increased forage yield for the same periods. The reduction in the number of root sections with Fusarium spp. was comparable for the nematicide and fungicide treatments and greater for the fungicide + nematicide treatment for two growing seasons. Nematode numbers were greater in fungicide-treated plots and forage yields were lower for two growing seasons. The nematicide and fungicide had no effect on forage yield, nematode numbers or fungus recovery in the third growing season. Plant persistence was not affected by the nematicide or fungicide, alone or in combination.

Abstract To optimize the growth of a hybrid poplar coppice plantation, a thinning trial was established in eastern Ontario. Four treatments were investigated: (1) thinning stools to one dominant sprout with residuals clipped at a height of 1 m (to increase operational efficiency of thinning), (2) thinning to one dominant sprout with residuals completely removed, (3) thinning to three dominant sprouts with residuals completely removed, and (4) no thinning. All treatments were performed at the beginning of either the third or fifth growing seasons (timing treatment one and two, respectively). When the 7-yr-old data were analyzed (i.e., 5 growing seasons after timing treatment one and 3 growing seasons after timing treatment two), thinning did not increase dominant sprout growth and significantly larger quantities of wood fiber were produced with lower thinning intensities or no thinning because of the greater number of sprouts per stool. Results of this trial suggest there is no advantage to thinning hybrid poplar coppice after the beginning of the third growing season. North. J. Appl. For. 8(4):166-168.

AbstractSmooth brome and Kentucky bluegrass are introduced cool-season perennial grasses known to invade grasslands throughout North America. During the fall of 2005 and spring of 2006, we implemented a restoration study at six native prairie sites in eastern South Dakota that have been invaded by smooth brome and Kentucky bluegrass. Treatments included five herbicide combinations, a fall prescribed burn, and an untreated control to determine the potential of each for renovation of invaded native grasslands. Herbicide treatments tested were sulfosulfuron, imazapyr, imazapic + sulfosulfuron, and imazapyr + imazapic, and were applied in late September 2005 and mid-May 2006. Untreated control plots averaged 64% (± 3.1) smooth brome cover and 38% (± 5.5) Kentucky bluegrass cover after the third growing season. Smooth brome cover in herbicide treated plots ranged from 6 to 23% and Kentucky bluegrass cover ranged from 15 to 35% after the third growing season. Smooth brome cover was 20% (± 2.9) and Kentucky bluegrass cover was 19% (± 4.0) in burned plots after the third growing season. Spring and fall treatments had similar native plant cover after three growing seasons. Spring and fall application of 0.33 kg ai ha−1 imazapyr and 0.10 kg ai ha−1 imazapic + 0.16 kg ai ha−1 imazapyr had ≤ 10% smooth brome cover and increased native species cover after three growing seasons. Herbicides were effective at reducing cover of smooth brome and Kentucky bluegrass, and can be incorporated with other management strategies to restore prairie remnants.

Variability in growth rates during the first three growing seasons of cod (Gadus morhua) in the southern Gulf of St. Lawrence was investigated by back calculation of length at a particular age from a body–otolith relationship. The data suggested that cod year classes partially recruited to the commercial fishery had larger back calculated l1 lengths than did fully recruited year classes. There was no relationship between length at the end of the first growing season and length at the end of either the third or fourth growing season. Growth compensation occurred in the second and third growing seasons. Size of age 0 cod was inversely correlated with biomass of spring-spawning herring (Clupea harengus) and not significantly correlated with year-class abundance of cod.
