Range Extension For Burrowing Crayfish Procambarus (Girardiella) Gracilis (Bundy), Joan P. Jass

Field Station Bulletins

The range of Procambarus (Girardiella) gracilis (Bundy) runs in a fairly narrow band southwest of Wisconsin through Illinois, Iowa, Missouri and Arkansas to the eastern edges of Nebraska, Kansas, Oklahoma and Texas. It extends into Wisconsin only in the southeastern corner of the state, having been previously reported only as far north as Milwaukee County. Within this range Hobbs and Rewolinski (1985) have described its habitat to be regions that were originally prairies.

Seedbanks And Vegetation Of Disturbed Urban Soils, Lynn Young Janik, Forest Stearns

Field Station Bulletins

The composition of urban seedbanks differed considerably from that of the established vegetation. Annuals were more abundant in the seedbank than in the vegetation, while perennials were more abundant in the vegetation. Many species were present in the seedpools and not in the vegetation, and the converse was also true. Seed dispersal and/or longevity was demonstrated by the presence of ten species, not growing in the vegetation, that emerged from the seedbanks of five or more of the six sites. In the vegetation, as in the seedbanks, introduced rather than native plants were the most common, including: bluegrass (Poa pratensis), …

Purple Loosestrife (Lythrum Salicaria): Its Status In Wisconsin And Control Methods, James A. Reinartz, James W. Popp, Margaret A. Kuchenreuther

Field Station Bulletins

Data were gathered in 1984 on the distribution, size, and habitat of populations of purple loosestrife in Wisconsin. Lythrum salicaria was found throughout Wisconsin, but most populations were still small and amenable to eradication with spot applications of herbicide. We compared the effectiveness of three dosages of glyphosate herbicide for eradicating small populations of purple loosestrife. High dosage treatments killed a slightly higher percentage of loosestrife than low dosage, but also caused much greater destruction of desirable perennial vegetation. The increased disturbance associated with high dosage, led to a high density of purple loosestrife seedlings in the following year. Low …

The Distribution Of Sarracenia Purpurea (Pitcher Plant) In Southeastern Wisconsin Fens: The Influence Of Ph And Nutrients, Teresa A. Golembiewski, Forest Stearns

Field Station Bulletins

Temperature, pH, alkalinity, total-N, total-P, K, Na, Ca and Mg levels were measured in groundwater at the Pickerel Lake and Ottawa Lake calcareous fens and the Cedarburg Bog patterned fen. The two calcareous fens were similar in all chemical characteristics. Alkalinity, pH and Mg were significantly lower in the patterned fen when compared to the calcareous fens, while the other chemical parameters were similar. Each of these southeastern Wisconsin fens supported Sarracenia purpurea (pitcher plant). When the characteristics of the groundwater of the areas that supported S. purpurea were compared with those of areas that did not support S. purpurea, …

Effect Of Time And Depth Of Planting On Survival And Growth Of Loblolly Pine (Pinus Taeda L.) Seedlings In Texas, M. Victor Bilan

Faculty Publications

Loblolly pine seedlings were lifted from a nursery bed in two-week intervals (November 4-April 21) and were immediately planted in an open field. Each planting included seedlings planted at the root collar (A), one-half of shoot buried (B) and most of the shoot buried except for the one-inch terminal (C). Average mortality during the first year was 10%, 13% and 16% for the A, B and C planting depths, respectively; the corresponding values for the second year mortality were 2%, 3% and 5%. Average first year mortality by the planting periods ranged - 24% with the highest values for April …

Management And Pest Management Considerations On Droughty Soils: Four Year Results, David Kulhavy, Kenneth G. Watterson, James Kroll, James R. Meeker

Faculty Publications

Four year survival of pines on droughty (Typic Quartzips~mments) soils was best for longleaf pine and Terr-Sorb -treated loblolly pine. Pest considerations include town ants and Nantucket pine tip moths on loblolly pine. Untreated loblolly pine had reduced leader and total height growth anH increased tip moth infestations, compared to Terra-Sorb and clay-slurry treated loblolly pine. Soil texture averaged less than eight percent silt and clay combined in the treatment areas.

Basic Mathematical Programming Applications To Weed Control In Forestry, Steven H. Bullard, R. H. Richardson, Thomas J. Straka

Faculty Publications

Many studies document herbicide performance for Heed and hardwood control in forestry. Few studies, hoHever, attemp t to develop optima l application strategies. Stand-level optindzation is presently limited due to lack of groHth and yield information. Forest-level optimization is possible, however, and has great potential to aid in planning forestry weed control prog rams.

State Cost-Share Programs For Nonindustrial Private Forestry Investments, Thomas J. Straka, Steven H. Bullard

Faculty Publications

Fourteen states provide cost-share assistance for approved forestry practices. Host programs are intended to increase forest productivity. Funding is typically from state appropriations and/or taxes on primary forest products. Cost-share rates range up to 80 percent, but most programs are at the 50 percent level. All programs require an approved forest management program. Eligible practices are generally reforestation, site preparation, and timber stand improvement.

Structural Analysis Of The Pacific Northwest Lumber And Plywood Industries, James G. Strathman, Anthony M. Rufolo, M. Hossein Haeri

Center for Urban Studies Publications and Reports

The lumber and plywood industries in the Pacific Northwest were particularly affected by the 1979-1982 construction recession. A subsequent recovery in output has occurred, but employment levels have remained relatively depressed. The potential for a planned reduction in the amount of timber sold from the national forests in the region also exists, giving rise to some uncertainty about the future prospects for these industries. This paper identifies the major structural factors affecting the performance of lumber and plywood producers in the region. It then proceeds to develop and simulate a set of alternative scenarios covering the 1986-1990 period to examine …

Vexar Seedling Protectors Did Not Reduce Nutria Damage To Planted Baldcypress Seedlings, William Conner, John R. Toliver

Publications

Vexar seedling protectors were tested for preventing nutria damage to baldcypress (Taxodium distichum (L.) Rich) seedlings planted in Louisiana
swamp forests. Five areas were planted with 1-year-old baldcypress seedlings. Half the seedlings in each area were protected with Vexar seedling protectors. The protectors slowed down the rate of destruction in some areas, but after 3 months, 85% of the guarded seedlings and 87% of the unguarded seedlings were destroyed.

Forest Conservation In Nepal: Encouraging Women's Participation, Augusta Molnar

Poverty, Gender, and Youth

This issue of SEEDS focuses on ways in which women have been involved in a government forest conservation and restoration program in Nepal. As is common with many large-scale projects with a general impact, women were not a direct focus of the project's original design. As activities got underway, however, both the Nepali staff and their expatriate colleagues quickly realized that the direct involvement of women was crucial to the success of the project's participatory strategy. Over the initial five years, 1980 to 1985, a number of approaches to addressing women's needs and generating their active participation were tried. The …

Characteristics Of Successful Competitors: An Evaluation Of Potential Growth Rate In Two Cold Desert Tussock Grasses, Eissenstat D. M., Caldwell M. M.

Aspen Bibliography

Within the first few weeks after seedling emergence, Agropyron desertorum, a more competitive tussock grass, had a much higher mean relative growth rate (RGR) than Agropyron spicatum, a very similar, but less competitive species. However, beyond the early seedling stage, the two grasses had a remarkably similar whole-plant RGR in hydroponic culture and aboveground RGR in glasshouse soil, if root temperatures were above approximately 12° C. At soil temperatures between 5 and 12° C, A. desertorum exhibited a 66% greater aboveground RGR than A. spicatum (P < 0.05). Both species responded similarly to warming soil temperatures. In the field, however, tiller growth rates were generally similar. Neither species showed marked tiller elongation until a couple of weeks after snowmelt, by which time soil temperatures, at least to a depth of 10 cm, were above 12° C for a significant portion of the day. Above-ground biomass accumulation over a three-year period indicated that both grasses had similar potential growth rates whereas Artemisia tridentata ssp. vaseyana, a common neighbor planted in the same plots, had a much greater potential growth rate. The greater competitive ability of adult A. desertorum, as compared to A. spicatum, cannot be attributed to appreciable differences in potential growth rates.

Aspen Sucker Damage And Defect In Colorado Clearcut Areas, Thomas E. Hinds, W.D. Shepperd

Aspen Bibliography

Substantial acreages of aspen in the Rocky Mountains are being regenerated by clearcutting; however, there is little information on the quality of the suckers that reestablish in these areas. Whether the new stands will be more or less defective than their predecessors is unknown.
