Thickening of woody vegetation has degraded numerous ecosystems globally. In forests, thickening often follows gap‐creating disturbance that removes mature trees and promotes the dense recruitment resprouts or seedlings. Restoration thinning seeks to reduce tree densities in thickened forests hasten recovery stand structure for habitat other conservation outcomes. However, as restoration involves disturbance, it may stimulate further recruitment. We investigated responses river red gum (...
Abstract Large tree decline is occurring globally with critical implications for biodiversity and carbon sequestration. Restoration thinning a potential management action to accelerate growth promote large development in forests, yet trials have been limited results mixed. We conducted large‐scale trial determine whether restoration could the of trees river red gum forests Australia that had experienced widespread woody thickening due long‐term commercial timber harvesting regulation....
Summary Uncertainty in assessments of vegetation condition that are used to inform land management and planning decisions for biodiversity conservation Australia may lead unexpected outcomes, including loss biodiversity. This study investigates observer error field estimates attributes, one component uncertainty condition. Ten observers conducted using two assessment protocols (BioMetric Habitat Hectares) on 20 sites a grassy woodland community. Observers’ varied substantially across...
To support the persistence of Australian eucalypt woodlands, conservation remnant vegetation must be augmented with ecological restoration degraded ecosystems. Certainty about effectiveness interventions is urgently required to consistently transition woodlands reference states. The aim this meta‐analysis was quantify improve plant and edaphic attributes in temperate semiarid Australia. Our structured literature search retrieved 35 studies that were suitable for analysis, which enabled...
Abstract With inadequate resources to manage the threats facing biodiversity worldwide, achieving projected management outcomes is critical for efficient resource allocation and species recovery. Despite this, conservation plans mitigate rarely articulate likelihood of success. Here we develop a general value information approach quantify impact uncertainty on 20 threatening processes affecting 976 listed communities. To our knowledge, this most comprehensive quantification impacts threat...
The meanings of vegetation condition. David Keith1 and Emma Gorrod1,2 (NSW Department Environment & Conservation, PO Box 1967, Hurstville, NSW 2220. Tel.: (02) 9585 6498; Fax: 6606; E-mail: [email protected]; 2Botany Department, University Melbourne, Parkville Vic. 3052, Australia). Key words: biodiversity conservation, conservation policy, natural resource management, uncertainty, assessment. Introduction. ‘Vegetation condition’ is a concept that has rapidly gained currency in recent land...
Abstract In many parts of the world, achieving a target 30% land managed for conservation under Kunming‐Montreal Global Biodiversity Framework will require protection with long history management production. newly protected forests, past logging practices have impacted key aspects stand structure, including hollow‐bearing trees that provide critical habitat vertebrate fauna. The impacts silvicultural on hollow density, distribution, type and longevity may necessitate targeted ameliorative...
Newly protected areas often have land-use legacies that affect their capacity to deliver conservation outcomes into the future. The management actions required achieve may be uncertain. This uncertainty resolved through experimental adaptive draws on knowledge of ecology and history ecosystem. In New South Wales, Australia, river red gum (Eucalyptus camaldulensis) floodplain forests were gazetted as National Park in 2010, including Murray Valley Park. Land-use had resulted one-third...
Abstract Evaluating the effectiveness of management actions for threatened species recovery is critical adaptive management. However, decision makers frequently lack resources and time to develop data‐driven models rigorous monitoring evaluation. Expert knowledge can be useful in such situations, but challenging translate into specific expectations about system responses. We describe a case study Saving Our Species program New South Wales, Australia, showing how an integrated process drawing...

Information on the distribution of trees with different diameters at breast height (DBH) is needed to inform management programs aimed achieving conservation objectives in high stem density forest stands. This article explored feasibility mapping DBHs using airborne LiDAR data. Experiments were conducted largest river red gum world, located southeast Australia.

Abstract Global declines in ecosystem extent and condition mean there is an increasing demand for recovery conservation plans. Conservation plans ecological communities require a management framework with measurable, time‐bound objectives. Efficient structured processes that facilitate timely comparable are essential, especially where resources constrained. We describe process to streamline the development of by combining functionally similar community sub‐types into multi‐community State...
Abstract Managers must determine which interventions best protect threatened species when the outcomes of are uncertain. Adaptive management is a dynamic optimization approach that generates optimal actions based on current knowledge while learning to improve future outcomes. Although adaptive theory well‐developed, uptake has been impeded by its complexity and tendency develop bespoke solutions with high implementation costs for problem‐specific returns. To increase threat recovery, we...
The global decline in the extent and condition of ecological communities has resulted an increasing demand for recovery conservation plans. Conservation plans require a management framework with measurable, time-bound objectives, targeted strategy, indicators that enable actions to be evaluated relation objectives. Methods allow transfer knowledge among similar systems facilitate consistent comparable are essential, especially when resources constrained. We describe process streamline...
