Establishing Pastoralist Monitoring Sites In The Grasslands: A Guide For Pastoralists, Department Of Primary Industries And Regional Development May 2020

Establishing Pastoralist Monitoring Sites In The Grasslands: A Guide For Pastoralists, Department Of Primary Industries And Regional Development

All other publications

This guide is for lessees and station managers who wish to establish rangeland condition monitoring programs for their pastoral leases. The guide outlines the main principles to consider for establishing monitoring sites, and the collecting and recording data to monitor changes over time of rangeland condition within a grassland environment.

Identifying and ongoing monitoring of representative sites can be used to objectively assess the effect of livestock numbers, fire and seasonal conditions on the health of the perennial vegetation and soil. Importantly, monitoring can assist lessees demonstrate whether their current land management practices are appropriate for achieving acceptable rangeland condition.


Remote Sensing And Gis Techniques For Forage Production Assessment And Management Of Northern Chhattisgarh In India, Nur Salim Ekka, S. K. Gupta Feb 2020

Remote Sensing And Gis Techniques For Forage Production Assessment And Management Of Northern Chhattisgarh In India, Nur Salim Ekka, S. K. Gupta

International Grassland Congress Proceedings

Grasslands play a vital ecological and environmental role in global carbon balance and climate change. In the prairie provinces of Canada, grasslands occupy approximately 25 M ha of the land base and provide a valuable resource to the multi-billion dollar cattle industry. In recent years, remote sensing technology has been applied for estimating the fractional cover of arid grasslands and savannah ecosystems (Asner and Heidebrecht, 2003; Marsett et al. 2006; Guerschman et al., 2009). Grassland, a specific ecosystem, occurs naturally on all continents excluding Antarctica (White et al., 2000). Remote sensing imagery needs to be converted into tangible information which ...


Planning For The Peel Food Zone, Heather M. Percy Feb 2020

Planning For The Peel Food Zone, Heather M. Percy

All other publications

The Planning for the Peel Food Zone project is part of Phase 1 of the Transform Peel initiative.Transform Peel is intended to be a ‘disruptive’ long-term program that supports economic growth, diversification and creates jobs in the Peel region. Transform Peel recognises the importance of protecting the internationally recognised waterways and wetlands of the Peel–Harvey Estuary and aims to halve the nutrient loads entering its waterways from the surrounding catchment.

The $49.3 million Phase 1 program for Transform Peel comprises three main components: Peel Food Zone; Peel Integrated Water Initiative; Peel Business Park.

This report summarises the ...


The Impact Of Automobile Tires On The Environment From The Period Of Raw Materials To The Disposal Of Them, K. G. Karimova Mar 2019

The Impact Of Automobile Tires On The Environment From The Period Of Raw Materials To The Disposal Of Them, K. G. Karimova

Central Asian Problems of Modern Science and Education

In this article, all stages on the life cycle of automobile tires and technical ISO standards are used to assess. One of the life cycle of the use of tires, this time allocated to chemical and mechanical connections. Developing countries account the amount of tires in the press and processing methods, as well as used tires on the environment and human health impact of information.

A Student Led Investigation Of The Landscape Dynamics Of Campus Recycling, Brandon Mcbride, Cheryl L. Scott, David L. Kulhavy, I-Kuai Hung, Daniel Unger Jan 2019

A Student Led Investigation Of The Landscape Dynamics Of Campus Recycling, Brandon Mcbride, Cheryl L. Scott, David L. Kulhavy, I-Kuai Hung, Daniel Unger

Faculty Publications

Two senior undergraduate students within the environmental science division at Stephen F. Austin State University (SFASU) quantitatively diagnosed the environmental, ecological, and socioeconomic dynamics involved in plastic recycling. This study incorporated actively collecting recycled plastic bottles on campus to produce an enumerated analysis of recycling on campus; and to gain an understanding of the socioeconomics of recycling via an anonymous survey used to determine the recycling knowledgebase of natural resource students at SFASU. Undergraduate students, via their incorporation into a campus wide environmental site assessment of recycling plastic bottles, were able to apply their classroom knowledge to a real-world environmental ...

Nebraska Cooperative Fish & Wildlife Research Unit -- Staff Publications

Recreational fisheries (RF) are complex social-ecological systems that play an important role in aquatic environments while generating significant social and economic benefits around the world. The nature of RF is diverse and rapidly evolving, including the participants, their priorities and behaviors, and the related ecological impacts and social and economic benefits. RF can lead to negative ecological impacts, particularly through overexploitation of fish populations and spread of non-native species and genotypes through stocking. Hence, careful management and monitoring of RF is essential to sustain these ecologically and socioeconomically important resources. This special issue on recreational fisheries contains diverse research, syntheses ...


Effects Of Thinning And Prescribed Burning On Tree Resistance To Extreme Drought In A Sierra Nevada Mixed-Conifer Forest, California Usa, Chance C. Callahan Jan 2019

Effects Of Thinning And Prescribed Burning On Tree Resistance To Extreme Drought In A Sierra Nevada Mixed-Conifer Forest, California Usa, Chance C. Callahan

Theses and projects

Drought-induced tree mortality can drastically alter forest composition, structure, carbon dynamics, and ecosystem function. Increasingly, forest policy and management focuses on how to improve forest resistance and resilience to drought stress. This study used tree ring data at Teakettle Experimental Forest (TEF), a historically frequent fire mixed-conifer forest in the California Sierra Nevada, to quantify how prescribed fire and mechanical thinning conducted in 2001-2002 influenced stand and tree-level growth responses to the extreme California drought of 2012-2016. Overstory thinning and understory thinning significantly enhanced growth responses to treatments alone and treatments during the drought at the stand-level. In each year ...


Regulatory Obsolescence Through Technological Change In Oil And Gas Extraction, Timothy Fitzgerald Oct 2018

Regulatory Obsolescence Through Technological Change In Oil And Gas Extraction, Timothy Fitzgerald

William & Mary Environmental Law and Policy Review

Extraction of oil and gas from unconventional resources, recently enabled by technological innovations, revolutionized national and global markets. However, exploration and production still proceed under legacy regulations, mostly promulgated at the state level. The mismatch of modern production realities and historic regulatory structures creates opportunities for reducing conflicts that diminish economic value. This Article identifies regulations that originated under conventional extraction, and often enhance productivity in that setting, but create waste when applied to unconventional resources. Then, it identifies contractual solutions that have evolved as resource owners and extraction firms have adapted to new technologies. Contractual innovations help inform directions ...
