Urban Restoration Ecology: Investigating environmental change, ecological function, and enrichment planting
… to human health and well-being. The field of restoration ecology has rapidly developed as a response to ameliorate the damage by investigating how to re-build ecosystems. This branch of science generally posits that replacing lost structure, i.e. re-vegetation, will re-create ecosystems, but …

An Investigation into the importance of propagule provenance in restoration ecology
There is increasing concern among restoration ecologists that using non-local propagules in revegetation schemes may influence the success of grassland restoration. This research programme investigated the importance of propagule provenance in restoration schemes. In particular the work focused on …

Untangling clumps-factors influencing seedling ecology in a semi-desert, and the implications for restoration ecology
Facilitation between plants and patch dynamics are two common ecological processes in semi-arid regions. I tested the relevance of these processes to seedling establishment of perennial species on degraded landscapes in Namaqualand, South Africa. The species were grouped into two functional guilds, …

Strategic revegetation planning in an agricultural landscape: A spatial information technology approach
… of general landscape-scale principles into restoration ecology. New and established quantitative, spatial analytical techniques are used in environmental modelling, ecological assessment and in setting geographic priorities for strategic revegetation planning in the Mt. Lofty Ranges in South …

Evaluation of Ecological Function of Urban Riparian and Stream Systems: Guiding Ecological Restoration in Austin, Texas, USA
Restoration ecology seeks to restore ecosystem function and biodiversity in natural systems impacted by human activities. Restoration of riparian areas is a common recommendation of water management plans today and often deemed necessary to maintain ecosystem sustainability. Assessment of the …

Examining sources of ecological resilience to climate change for restoration planning
Restoration ecology is a burgeoning field and ecological restoration efforts are becoming more wide-spread. However studies reveal that many restoration efforts fail to accomplish their objectives because they do not address the root cause of degradation or because there is a mismatch between the …

The Ecology of Land Managers in Riparian Restoration
<p>While previous studies in restoration ecology have focused on the efficacy of direct management actions, the driving forces on management decisions (e.g., managers' characteristics or attitudes, environmental conditions) and the indirect impacts on restoration outcomes from management decisions …

Effect of Population Sources and Species Pools on Community Phylogenetic and Functional Diversity During Restoration
… of incorporating phylogenetic approach into restoration ecology to tease out the effect of population sources and species pools on community phylogenetic diversity (Chapter 2). This study was first study to show consequences of using different seed sources on phylogenetic diversity (PD) in …

Public Ecology: Linking People, Science, and the Environment
… of these programs (e.g., conservation biology, restoration ecology, sustainable forestry, environmental toxicology, and others) produces specialized knowledge that is used to achieve specific social and environmental goals. For example, the peer-reviewed, scientific analyses published in …

Tradeoffs among ecosystem services in restored wetlands
Recently restoration ecology and land management have found new focus and direction by emphasizing the value of ecosystem services to society. Resource management decisions frequently involve choices that reflect tradeoffs among ecosystem services. Tradeoffs occur when one service changes at the …

An Ecological Assessment of Restoration Efforts Developed to Recover an Intensively Mined Appalachian Watershed
<p>Assessments of watershed-based restoration efforts are rare. Monitoring of projects pre- and post-treatment are essential for the science of stream restoration ecology to advance. We took an experimental approach, following adaptive watershed management principles, to evaluate the effectiveness …

Ecological, Social, And Educational Dimensions Of Restoration: Insights From Berenty Reserve, Madagascar
Amidst a global biodiversity crisis, ecological restoration emerges as a critical solution to mitigate the devastating effects of biodiversity loss and climate change. Focusing on Madagascar, a biodiversity hotspot facing significant forest loss, this dissertation explores various aspects of …

Determining vegetation metric robustness to environmental and methodological variables, and coefficients of conservatism for the flora of the Middle Rio Grande, New Mexico
… metrics used in monitoring of ecological restorations include measures of vegetation structure and measures of species diversity and composition. Metrics of species diversity and composition are often used as proxies for overall biological diversity of a site, but some metrics may be …

Regional Rarity: Consequences of Dispersal Limitation and Strategies for Reintroduction
… habitats has been a longstanding goal of restoration ecology, particularly with respect to differences between rare and widespread species. Numerous mechanisms have been proposed to contribute to rarity, including species traits, propagule limitation, ecological requirements, and …

Heathland Restoration after Mineral Extraction
Restoration Ecology has been developed over the last 40 years in efforts to better understand how to restore, recreate or reclaim land damaged by human activities. Lowland heath is one of the more difficult habitats to recreate due to the complicated interactions of soil chemistry and plant …

Remediation and restoration of ocean exposed cliff-top, in the context of Dounreay (Scotland) nuclear power plant decommissioning
Restoration ecology continues to become ever more relevant as legislation demands we prevent biodiversity losses. Post-industrial restoration sites pose a number of additional challenges, including balancing ecological need with logistical and financial constraints. In the North of Scotland, one …

Processes determining plant species diversity in restored tallgrass prairie
<p>A fundamental goal of restoration ecology is to restore biological diversity in degraded or fragmented environments. In practice, restorations often have lower diversity than reference communities, highlighting a need to identify theoretical and practical barriers to the restoration of native …

A framework for river restoration planning : considering conceptual and structural perspectives from case studies of the Liao River in China and the Kalgan River in Australia
Over the last decade, restoration ecology has been considered a new paradigm for dealing with many of the environmental problems of river systems. It is also recognized that management decisions have a greater chance of being successful if they are based on a thorough understanding of a concept or …

Harakeke (Phormium tenax) ecology and historical management by Maori: The changing landscape in New Zealand
… project investigates Maori knowledge of harakeke ecology and management practices prior to the early 20th century within the context of a study of relevant environmental parameters that limit its natural distribution. Ecological information referring to harakeke was analysed from interviews with …
