National Invasive Species Council

Farmers, ranchers, scientists, State officials, and many others have urged the Federal Government to consider invasive species issues a priority and to develop a coordinated national effort to address the problem. In response, the President issued Executive Order 13112 on Invasive Species (Order) in February 1999. The Order established the National Invasive Species Council (Council), co-chaired by the Secretaries of Agriculture, Commerce, and the Interior; and includes the Secretaries of State, Treasury, Defense, and Transportation, and the Administrator of the Environmental Protection Agency. The Order directs the Council to form a non-Federal Invasive Species Advisory Committee (ISAC) to advise the …

Yellow Jackets (Vespula Spp.) Disperse Trillium (Spp.) Seeds In Eastern North America, Jennifer A. Zettler, Timonthy P. Spira, Craig R. Allen Jan 2001

Yellow Jackets (Vespula Spp.) Disperse Trillium (Spp.) Seeds In Eastern North America, Jennifer A. Zettler, Timonthy P. Spira, Craig R. Allen

Nebraska Cooperative Fish and Wildlife Research Unit: Staff Publications

Approximately 70 plant families worldwide have ant-dispersed seeds (myrmecochory). In this putative ant-plant mutualism, ants are attracted to and disperse seeds that have a lipid-rich elaiosome. We observed yellow jackets (Vespula spp.) dispersing seeds of three elaiosome-bearing species-Trillium cuneatum, T. undulatum and T catesbaei-in the Blue Ridge Mountains of North Carolina and South Carolina. Moreover, we estimated the mean distance yellow jackets dispersed seeds of T. cuneatum by placing intact fruits on index cards and recovering dispersed seeds on sheets placed on the ground surface. Of the seeds presented, 41% were recovered and the average dispersal distance …


2001 File Geodatabase Containing Photo Point Locations, Aerial Photos, And Flight Maps, City Of Tampa Department Of Sanitary Sewers Bay Study Group, Pete Reehling, Richard Mckenzie Jan 2001

2001 File Geodatabase Containing Photo Point Locations, Aerial Photos, And Flight Maps, City Of Tampa Department Of Sanitary Sewers Bay Study Group, Pete Reehling, Richard Mckenzie

Data Sets

The Bay Study Group was created by the City of Tampa in 1976 to monitor the effects of pollution abatement that occurred in Hillsborough Bay when the city’s wastewater treatment plant was upgraded from primary to advanced treatment in 1979. The Bay Study Group documented a remarkable restoration of water quality parameters and biological indicators in Hillsborough Bay from the mid 1980s until 2009, when it was disbanded. This zip Geodatabase file contains the photo point locations, aerial photos, and flight maps for the year 2001.


Burakin Focus Catchment Report, Mike Clarke Jan 2001

Burakin Focus Catchment Report, Mike Clarke

Natural resources published reports

The Burakin Focus Catchment Project was developed between farmers and Agriculture _ Western Australia. The project was designed to give farmers an understanding of the salinity processes occurring within the Catchment and suggestions on appropriate management.

Work began in the Catchment early in 1999 and was complete at the end of 2000. Intensive hydrological investigations formed the basis of the study, which was complemented by surface water control and revegetation strategies. Agronomic issues associated with sandplain soils were raised by the farmers at the initial meeting and this led to a soil survey to determine the pH status of the …


Farming Systems To Manage Salinity. Farmer Directed Research, Development And Extension. Research Results 2001, Richard Olive Jan 2001

Farming Systems To Manage Salinity. Farmer Directed Research, Development And Extension. Research Results 2001, Richard Olive

Natural resources published reports

More and more of Western Australia's agnicultural lands are becoming saline. Currently it is estimated that about 18 milliion ha of land are affected to a greater or lesser degree by salinity causing production losses estimated at about $70 million a year.

Unless ways are found to halt and reverse the salinisation of land it is estimated that another 4.4 million ha could become saline over the next 50 years.

Grain growers and the Federal Government, through the Grains Research and Development Corporation (GRDC). are investing $12 4 million in R&D across Australia to develop productive solutions to the salinity …


An Evaluation Of Environmental Disclosures Produced In Australian Local Government Annual Reports, Royston J. Tan Jan 2001

An Evaluation Of Environmental Disclosures Produced In Australian Local Government Annual Reports, Royston J. Tan

Theses : Honours

This thesis is an evaluation of the environmental disclosures published in Australian local governments' annual reports. The study is aimed in identifying disclosures of environmental information by Australian local governments and providing explanations for the variations in the quantity and quality of information disclosed. Various social responsibility theories were used in this study. The theories employed in this study were institutional factors, stakeholder theory, social and political theories. Institutional factors included issues such as local government characteristics and pressures exerted from various government and non·government organizations to implement and disclose environmental measures. A content analysis methodology was used in this …


Mine Dewatering In Arid, Saline Environments In Western Australia: The Response Of Biota Emerging From Rehydrated Sediments, Charelle Harkins Jan 2001

Mine Dewatering In Arid, Saline Environments In Western Australia: The Response Of Biota Emerging From Rehydrated Sediments, Charelle Harkins

Theses : Honours

Mine dewatering is a critical part of the mining process to prevent flooding of underground or open pits, to allow for the excavation of the available resources. Groundwater is abstracted from underground pits to the surface through extraction bores. The issue of where to discharge the excess water is a major concern. The use of natural wetlands is one option for mine water discharge. Saline lakes in arid areas are ideal receiving environments for discharge options, acting as evaporation facilities for the storage and disposal of excess mine water. Mine water discharge into ephemeral lake systems modifies the volume of …


Hydrogeological Study Of The Dongolocking Reserves, Dumbleyung, Western Australia, Ben Whitfield Jan 2001

Hydrogeological Study Of The Dongolocking Reserves, Dumbleyung, Western Australia, Ben Whitfield

Resource management technical reports

The aims of the hydrogeological study were to assess the characteristics of aquifers within the weathered zone, throughout the Dongolocking Reserves and in the surrounding farmland; provide baseline data on root zone salt store (EM38) and vertical distribution of stored salts (EM38) through the use of ground-based geophysical techniques; identify remnant bush at risk of salinisation; suggest management options to address any observed salinity problems; provide a groundwater monitoring network.


Assessing Methodologies For Identification Of Significant Impacts In The Iso 14001 Ems (Environmental Management Systems), Ann Wye-Wye Wang Jan 2001

Assessing Methodologies For Identification Of Significant Impacts In The Iso 14001 Ems (Environmental Management Systems), Ann Wye-Wye Wang

Student Works (2000-2009)

ISO 14001 is a voluntary environmental management system specification standard in the ISO 14000 series. It contains those elements that must be satisfied by an organisation seeking registration or certification to the standard. Identification of significant environmental impacts is one of the requirements as stated in clause 4.3.1 of MS ISO 14001 EMS - specification with guidance for use, and is an important step in the implementation of ISO 14001 standard. A study on the methodologies for identification of significant environmental impacts in the ISO 14001 EMS (Environmental Management Systems) was carried out. Three methods that have been developed are …
