Plant Conservation In The Juan Fernandez Archipelago, Chile, Tod F. Stuessy, Ulf Swenson, Daniel J. Crawford, Gregory Anderson, Mario Silva O.

Aliso: A Journal of Systematic and Floristic Botany

Oceanic archipelagos often hold very specialized floras with high degrees of endemism. These floras are frequently highly vulnerable to disturbance by natural causes and human intervention. The Juan Fernandez Islands (Chile) in the Pacific Ocean are a small archipelago of only three islands. Since discovery in 1574 by Juan Fernandez, human activities have altered floristic composition and survival circumstances of the endemic species. In this paper we document past and present means of disturbance, both anthropogenic and natural, which have influenced the native vegetation. The most destructive past activities have been logging and .introduction of animals and plants, both deliberately …

Population Structuring And Patterns Of Morphological Variation In Californian Styrax (Styracaceae), Peter Fritsch

Aliso: A Journal of Systematic and Floristic Botany

Recent studies of genetic variation within and among populations and phylogenetic estimates have provided evidence bearing on the evolutionary history and taxonomy of Styrax in California (S. redivivus). In this paper, data from these studies are further analyzed and integrated with new data from morphology to gain insight into the nature and taxonomic significance of character variation within this species. Six morphological characters thought to be important in the delimitation of infraspecific taxa within S. redivivus were measured on 52 herbarium specimens and analyzed with Pearson correlations and multivariate methods. Five characters are significantly associated with latitude and …

G96-1311 Global Warming: What Is Known And Why Nebraska Agriculture Should Care, William E. Easterling, Cynthia Hayes

University of Nebraska-Lincoln Extension: Historical Materials

The purpose of this NebGuide is to review the facts of global warming, to point out what is sheer speculation, and to suggest why Nebraska agriculture should care about global warming.

Climatologists talk about global warming one year and the next year they talk about global cooling! Depending on the time periods involved, both views may be correct. Over the next few hundred years, the earth may undergo a general cooling trend. This trend is consistent with the regular shifts into and out of ice age conditions that have characterized the earth's climate history of the last 50,000 years. However, …

Ec96-142 Conservation Reserve Program: Crp Land Use Guide, Douglas Anderson

University of Nebraska-Lincoln Extension: Historical Materials

Conservation Reserve Program (CRP) contracts held by Nebraska producers will begin to expire in 1996.

Potential For Crop Residue To Restrict Herbicide Movement In Surface From Water Corn And Soybean Fields, William W. Witt

KWRRI Research Reports

As no-tillage and other conservation tillage practices continue to increase, it is important to have knowledge of herbicide adsorption on crop residue with regard to the potential for the herbicide to be removed from the residue and move with runoff water from the field into nearby surface waters. Previous research had compared herbicide adsorption to various residues, but it was difficult to make comparisons among these studies because the residues were from different crops or the amount of residue decomposition was different. The amount of "weathering" or "aging" of the residue at the time of herbicide treatment could alter the …

Nf95-219 Common Ground: State Conservation Reserve, William Miller

University of Nebraska-Lincoln Extension: Historical Materials

The Conservation Reserve Program (CRP) has been a popular part of the federal farm program for the past several years because it contributes to farm income, soil conservation, and wildlife habitat. Landowners have found the annual payments for enrolling land in the CRP to be a financially attractive alternative to producing crops. Higher commodity prices due to fewer crop acres has been an additional benefit to landowners. Environmentalists have been pleased with the lower soil losses from the land and the improved stream environment associated with the CRP. Wildlife advocates are strong supporters of the CRP. For example, the Wildlife …

Procedures For The Administration And Assessment Of Clearing And Protection Of Native Vegetation In Western Australia, Alexander Mcrae Holm

Soil conservation survey collection

It is Department of Agriculture policy that regulation is only used when all other approaches to address land degradation have failed. Our thrust is to encourage land holders to move towards using land within its capabilities as they continue to adopt sustainable farming systems. Underlying this approach is a self regulatory philosophy with land conservation district committees playing an important management and coordination role. Nevertheless the community expects that land degradation will be controlled and legislation is available to underpin or complement the good intentions of most land holders. The Soil and Land Conservation Act is the legislation used to …

Ec94-1772 Windbreaks In Sustainable Agricultural Systems, James R. Brandle, Teresa Boes, Vernon Quam, John Gardner

University of Nebraska-Lincoln Extension: Historical Materials

Sustainable agriculture is a system of whole-farm resource use balanced with whole-farm productivity. The overall level of productivity achieved is dependent upon the ability to coordinate and manage simultaneously the soil, water, plant, and animal resources within climatic and economic limits. Both the kind and amount of plants and animals supported by the system are important and play significant roles, both individually and collectively in maintaining a healthy farm environment. In the future, integrated systems will help reduce human impact on resources while providing sufficient supplies of high quality food and fiber.

Windbreaks provide protection for people, animals, buildings, crops, …

Floristic Composition And Conservation Status Of Fens In Iowa, John A. Pearson, Mark J. Leoschke

Journal of the Iowa Academy of Science: JIAS

Over 200 extant fens of varying condition were documented during an extensive inventory conducted in Iowa between 1986 and 1991. Approximately half of the extant fens support endangered, threatened, special concern, or other rare plant species. Approximately 25 fens are outstanding conservation prospects with intact vegetation, high species richness, and rare species. Nearly 40% of all potential fen sites have been destroyed by cultivation or damage; another 30% remain unknown due to lack of a field visit, but most appear on aerial photographs to be very small, disturbed fragments. In addition to their traditionally recognized range in northwest Iowa, fens …

Managing Nature Reserves For Cranes In China, James Harris

Proceedings of the North American Crane Workshop

During the past 15 years, China has established more than 300 nature reserves. Many of the wetland reserves have been created primarily to protect endangered cranes. This paper summarizes the status of 22 nature reserves, 13 for breeding cranes and 9 for wintering cranes. The nature reserves have often been established in areas heavily populated or intensively used for economic purposes. Many reserves have been effective in stopping hunting of cranes. Taking of eggs or young has also been greatly reduced, but general human disturbances threaten successful nesting. Reserve authorities have also taken steps to prevent destruction or degradation of …
