Riparian plant communities, though small in overall area, are among the most valuable natural areas in the Southwest. The causes of degradation of southwestern riparian zones range from excessive cattle and elk grazing in montane watersheds to invasive woody exotic species and lack of natural flooding in the cottonwood forests, "bosque," of low elevation river valleys. Goals of riparian restoration include erosion control, channel stabilization, runoff reduction, and enhancement of wildlife and fishery habitat. Plant species and stock types selected for restoration efforts must be appropria...

The application of municipal wastewater to land for treatment and disposal, or "land farms," was one of the earliest forms of wastewater treatment technology. There has been renewed interest in using these systems in arid regions worldwide to supplement and reuse dwindling water resources. However, arid regions present complex challenges to the use of land application systems. Many arid regions (for example, Egypt and US/Mexico border) are located in areas that lack infrastructure support and cannot afford expensive treatment technologies. A slow-rate, land application system offers a...

Long tubes are a new stock type developed specifically for restoration of challenging sites such as disturbed riparian areas. Constructed out of polyvinyl chloride plastic pipe, long tubes have a Vexar lining to promote good root growth and easier extraction. The expandable stinger is a new invention that was developed to outplant long tubes. The stinger is attached to an excavator, which hydraulically operates a metal beak that holds the long tubes in place while they are planted. The expandable stinger has been used to plant stream gravel bars and road cut and fill slopes, but has other...

A variety of treatments have been employed to restore riparian areas affected by wildland fire on the Six Rivers National Forest in northwestern California. The Megram Fire began as a series of lightning strikes on August 23,1999, eventually burning 125,040 acres. Specific treatments have included contour felling of dead trees, straw mulching, placement of straw wattles, helicopter seeding of non-native, non-persistent barley, planting trees and shrubs, and introducing and/or reconfiguring woody debris designed to enhance stream channel stability. In addition, lessons learned from several...

Of the original tidal salt marshes around the San Francisco Bay, only about 5% remain. There have been many mitigation projects undertaken in this bay over the last 10 years. Depending on funding, projects have simply regraded the mudflats to provide habitat and some projects have included seeding or planting of native halophytic plants. However, most of these projects in which planting was done have included only the 8 or 10 most common species. The intact remnant marshes contain a diverse flora of 30 to 35 species. Monitoring of these projects has shown that the other uncommon but...

Menominee Tribal Enterprises (MTE) is located in northeastern Wisconsin on the Menominee Indian Reservation, which includes ten townships of mostly forested land. Past fires, windstorms, and logging all have affected the composition and structure of this forest, which brings us to why regeneration on the forest is very important. Stands are regenerated with tree planting or through natural regeneration using shelterwoods.

Hakalau Forest NWR was established in 1985 under the authority of the Endangered Species Act to preserve and protect five species of endangered forest birds and their rain forest habitat. While most of the 32,730 acre refuge is closed canopy forest, over one hundred years of cattle grazing, logging and burning have convened about 5,000 acres (2,023 ha) of upper elevation forest into open woodland and pasture dominated by introduced grasses. Other portions of the refuge encompass relatively intact native forest including some of the last montane, mesic koa-'hi'a (Acacia koa-Metrosideros...

As the director of the Minnesota Tree Improvement Cooperative (MTIC) based in Cloquet, Minnesota, I would like to tell you a little about our strategy for creating improved seed, and how individual nurseries or nursery associations can interact with tree improvement programs to the benefit of both parties. MTIC is approximately 15 miles west of Duluth, at the University of Minnesota's Cloquet Forestry Center.

Aloha Kakahiaka, Buenos Dias, Guten Morgan or however you may say good morning. It's so wonderful to see so many of you, especially those that have traveled from foreign countries to be here to learn and share your experiences in the nursery area. On behalf of Mike Buck, Division of Forestry and Wildlife (DOFAW) Administrator, welcome to the Western Forest and Conservation Nursery Association meeting here in Kailua-Kona, Hawaii. My name is Carl Masaki, and I'm the forestry program manager for the Division of Forestry and Wildlife, Department of Land and Natural Resources, State of Hawaii....

Demand for hardwood tree seedlings is currently at an all time high.
