Rangeland Monitoring: Analysis, Interpretation, And Evaluation, United States Bureau Of Land Management
All U.S. Government Documents (Utah Regional Depository)
The collection of monitoring data results in quantitative and qualitative information obtained from measurements or estimates of the natural resources. These data are most valuable when their meaning is defined and presented in understandable terms to the resource manager. This is the analysis, interpretation, and evaluation process. The result is the documentation of conclusions on the progress of management to accomplish specific management objectives. Such conclusions are used for management and planning purposes, and in particular, for determining managment actions and establishing new or revised management objectives.

Canyonlands National Park And Orange Cliffs Unit Of Glen Canyon National Recreation Area Environmental Assessment For Backcountry Management Plan, National Park Service
All U.S. Government Documents (Utah Regional Depository)
Whether on foot, bicycle, horseback, or in vehicles, most visitors come to Canyonlands National Park (Canyonlands) to experience solitude or to "get away from people." Yet visitation to Canyonlands has risen exponentially over the past five years (Figures 1 and 2). Visitation is expected to continue to rise. As a function of this increase in number of visitors, adverse impacts to Canyonlands' resources have increased and the visitors' ability to find solitude has decreased. Since the mandate of the National Park Service (NPS) is to balance visitor access to the parks with preservation and protection of natural and cultural resources, …

United States Department of Commerce: Staff Publications
Zebra mussels, Dreissena polymorpha, were collected monthly from April/May to November in 1990 and 1991 from two sites in Lake St. Clair. The sites were characterized by relatively high and low mussel densities. The following variables were measured: ash-free dry weight (AFDW) per unit shell length (SL), lipid content and classes, carbon content, and nitrogen content. Mussels from the high-density site had a lower AFDW:SL relationship, lower lipid content, and a lower C:N ratio than mussels from the low-density site. Seasonal trends in these variables were consistent between sites and years. AFDW:SL, lipid, and carbon content were highest in …

Honey Production In Western Australia, Rob Manning
Honey Production In Western Australia, Rob Manning
Journal of the Department of Agriculture, Western Australia, Series 4
the first ever survey of the potential production and value of apiary products from the south-west of Western Australia has shown beekeepers are collecting only 10 per cent of the potential honey crop.
The biggeest losses in honey production are caused by the enviroment, such as protracted drought, and extreme temperatures, heavy rain and cyclones during flowering. Fire, apiary sites leased but not used, and logging of forests also reduce the availability of apiary sites for honey production.

Controlling Wind Erosion In Field Pea Stubbles, Jeff Russell
Journal of the Department of Agriculture, Western Australia, Series 4
The area sown to field peas in Western Australia's eastern wheatbelt has increased from 4000 ha in 1985 to about 35, 000 ha in 1992.
While field peas can be grown on soil types not suited to lupins, their stubble is highly fragile and prone to wind erosion, even at low grazing pressure. This is one reason why some farmers are hesitant to grow field peas.
Haroest losses of field peas can also be high; levels of JOO to 200 kg/ha of seed on the ground are not uncommon. For this reason farmers believe the stubbles should be grazed.

Albany Harbours Sampling Program - Experiences, Myths And The Need For Standards, David Weaver
Albany Harbours Sampling Program - Experiences, Myths And The Need For Standards, David Weaver
Conference papers and presentations
Making accurate and precise estimations of pollutant loadings is becoming more important as our waterways suffer from increased inputs of pollutants and as statutory requirements to meet target loads are established. The most studied pollutant in waterways in WA is phosphorus (P) since it is reported to be the stimulus for algal growth. Many reports publish nutrient load data without any discussion of potential errors in sampling, chemical analysis or load calculations, or any discussion of the assumptions made and conclusions drawn from those calculations. The result can be the adoption of incorrect sampling, analytical and calculation procedures, leading ultimately …

The Potential Environmental Consequences Of Utilizing Sewage Sludge As Fertilizer On Agricultural Lands: A Case Study Of The Region Of Waterloo (Ontario), Benjamin C. Mohabir
Theses and Dissertations (Comprehensive)
With the advent of increased volumes of liquid sewage sludge being produced in the world annually, means of disposal and recycling have become a serious issue. The disposal of sludge onto agricultural lands has raised concern regarding its environmental implications. The concern stems from the presence of toxic substances often found in sludge which can be harmful to the environment. The sludge utilization programme in the Regional Municipality of Waterloo has shortcomings in the areas of site evaluation and monitoring, and setting an application agenda tied in with a weather forecasting system. These shortcomings combined with the physical characteristics of …
Criteria For Predicting Zebra Mussel Invasions In The Mid-Atlantic Region, Patrick Baker, Shirley Baker, Roger Mann
Criteria For Predicting Zebra Mussel Invasions In The Mid-Atlantic Region, Patrick Baker, Shirley Baker, Roger Mann
Reports
What is the probability that zebra mussels will invade specific bodies of water within a given state? If they do invade, will they become economic and ecological pests as they have in portions of the Great Lakes? These and similar questions are addressed, with the expectation that management strategies can be developed to delay, mitigate, or possibly even prevent zebra mussel invasions, in some areas.
