A Model Of Coppice Biomass Recovery For Mallee-Form Eucalypts, Kim Brooksbank, Adrian Goodwin Mr Jul 2021

A Model Of Coppice Biomass Recovery For Mallee-Form Eucalypts, Kim Brooksbank, Adrian Goodwin Mr

Journal articles

Planting mallee-form eucalypts amongst crops has the potential to remedy environmental degradation caused by land clearing in low rainfall regions, whilst also providing income through carbon-sequestration or periodic coppicing. Management options can be supported by models of biomass and coppice recovery, and this paper presents the first empirical coppice growth model for mallee eucalypts.

Uncoppiced and coppiced belt-planted Eucalyptus polybractea, E. loxophleba and E. kochii were harvested and roots excavated to provide estimates of shoot and root biomass for analysis and model development. Allometric models of shoot biomass were appropriate for both uncoppiced and coppiced trees, but models of …


Salinity Risk Mapping For Assessing Carbon Farming Initiative Proposals: Decision Support And Data Requirements, Paul Raper, Peter Gardiner Apr 2014

Salinity Risk Mapping For Assessing Carbon Farming Initiative Proposals: Decision Support And Data Requirements, Paul Raper, Peter Gardiner

Resource management technical reports

The Clean Energy Legislation passed by the Australian Parliament on 8 November 2011 links the carbon price to the Carbon Farming Initiative (CFI). Under the Carbon Credits (Carbon Farming Initiative) Act 2011 (the Act), proponents need to consider regional natural resource management (NRM) plans to ensure that tree plantings for carbon bio-sequestration maximise environmental benefits and avoid unintended adverse effects on biodiversity, water and agricultural production systems.

Fire Management Guidelines For Southern Shrubland And Pilbara Pastoral Rangelands : Best Management Practice Guidelines, Department Of Agriculture And Food, Western Australia Apr 2006

Fire Management Guidelines For Southern Shrubland And Pilbara Pastoral Rangelands : Best Management Practice Guidelines, Department Of Agriculture And Food, Western Australia

Land resources best practice series

Fire is integral to many ecosystems in Western Australian rangelands. Controlled fire can reduce the risk of wild fire, benefit pasture productivity and contribute positively to biodiversity values. Uncontrolled fire is a threat to safety and the business viability of pastoral enterprises and threatens rangeland biodiversity and productivity.This document deals with property-scale management of pastoral leases. Many fire regime issues are more regional in character. These include community safety and health, the impact on regional economies, the societal and cultural values of landscape and the effects on tourism. Ecologically the high productivity, diversity and palatability of recently burnt vegetation is …


The Grazing Of Cattle In The Southern Pastoral Areas Of Western Australia, Department Of Agriculture And Food, Western Australia Apr 2006

The Grazing Of Cattle In The Southern Pastoral Areas Of Western Australia, Department Of Agriculture And Food, Western Australia

Land resources best practice series

The Land Administration Act 1997 requires a pastoralist to manage and work the land within a pastoral lease to its best advantage and use methods of best pastoral and environmental management practice to achieve sustainable land use. The Pastoral Lands Board will use these best management practices as a guideline.

Fire Management Guidelines For Kimberley Pastoral Rangelands : Best Management Practice Guidelines, Department Of Agriculture And Food, Western Australia Apr 2006

Fire Management Guidelines For Kimberley Pastoral Rangelands : Best Management Practice Guidelines, Department Of Agriculture And Food, Western Australia

Land resources best practice series

Kimberley pastoralists operate in a highly fire-prone environment. Uncontrolled fires pose significant economic, safety, and environmental risks to pastoral enterprises. In contrast, the controlled use of fire can benefit land management, animal production and biodiversity conservation. For any given country type, the interactions of fire, grazing and weather have complex effects on both land condition and animal production. Although general guidelines on the use of fire are valuable, based as they are on a combination of experience and available research findings, they should best be regarded as providing a starting point. At the property level, an adaptive approach that incorporates …

The Physical And Hydrological Characteristics Of A South Coast Sandplain Site : East Howick Site Survey, Robert Anthony Sudmeyer Jan 1998

The Physical And Hydrological Characteristics Of A South Coast Sandplain Site : East Howick Site Survey, Robert Anthony Sudmeyer

Resource management technical reports

This Technical Report documents the physical and hydrological characteristics of a farmland site on the Esperance Sandplain. The site was located on 'Belalie Farm East' 110 km east of the town of Esperance in the locality of Howick (AMG 488900, 6277500) The site was typical of the sandplain landsystem which covers 35% (0.72 million ha) of the Esperance Agricultural Region. The farm was cleared over a number of years beginning in the 1970's and an extensive network of windbreaks established.

Remnant Vegetation And Natural Resources Of The Blackwood River Catchment An Atlas, Shaun B. Grein

Agriculture reports

The Blackwood River is one of the longest rivers in the South-West of Western Australia, stretching 300 km from Moordjarrup to August. The catchment covers more than 28,000 square kilometres (2.8 million ha) from the Shire of Kent to the Shire of Augusta-Margaret River. It incorporates 17 shires, more than 30,000 people, 18 Land Conservation District Committees (LCDCs) and 143 sub-catchment groups. Shires within the Blackwood Catchment cover 4.12 million hectares, over half of the total area of the shires that fall within the catchment boundary.


Parrot Damage To Bluegum Tree Crops : A Review Of The Problem And Possible Solutions, P Ritson Nov 1995

Parrot Damage To Bluegum Tree Crops : A Review Of The Problem And Possible Solutions, P Ritson

Resource management technical reports

Damage to Bluegum (Eucalyptus globulus) tree crops by the Twenty-eight Parrot (Barnardius zonarius) is emerging problem which could threaten the viability of the infant Bluegum industry in south-western Australia. The parrots strip bark from the lead shoot of the Bluegums causing the shoots to break off. Consequently lateral shoots develop resulting in deformed (bent or multi-stem) trees unsuited to harvest and utilisation.Indications that the reason Twenty-eight Parrots strip bark from Bluegum is to obta behaviour' and hence the damage may also develop in areas where it is absent or uncommon now. Currently the zone of worst damage includes around 20% …
