“Landscape ecology emphasizes the interactions between spatial patterns and ecological processes, that is, the causes and consequences of spatial heterogeneity in a range of scales” (Turner et al. 2001). Landscape ecology provides a foundational framework for problem solving, decision making and planning in land restoration, ecological conservation and natural resources management. It covers topics related to structure, function and change, and it provides the necessary tools to select the appropriate methods to test spatial hypothesis and solve problems at multiple scales. This module is designed to introduce you to a variety of tools that measure and quantify landscape components at different scales, and to understand them in the context of their field of expertise priorities and regulations.

• Landscape metrics (e.g. spatial pattern metrics)
• Landscape fragmentation, connectivity, scale and hierarchy

• Design strategies to quantify spatial patterns, spatial structures, and species at the relevant scales.
• Select the appropriate quantitative methods to test spatial hypotheses, solve problems, inform monitoring programs, and interpret the findings in the context of conservation priorities and conservation law.
• Evaluate monitoring data to guide decision making in ecosystem management.

Successful ecological restoration and rehabilitation requires an integrated understanding of the ecological parameters of a site, together with the physical, chemical, and biotic factors that may influence desired outcomes. However, restoration objectives also need appreciation of the historical context of the site, as well as possible social considerations that may limit the desired outcomes. In short ecological restoration is frequently ‘the art of balancing the possible’. This module covers the breadth of considerations required for ecological restoration and gives you the opportunity to undertake analysis of management planning at both site and landscape scales.

• Abiotic and biotic controls on community composition.
• Practical techniques for effective habitat creation and restoration.
• Habitat management for faunal conservation.
• Effects of changes in climate and land use on conservation practices.
• Habitat case studies; for example wetland, grassland, woodland, heathland, riparian buffer strips.
• Importance of scale for reconstruction of habitats.

On successful completion of this module you should be able to:

• Discuss the principles underlying restoration ecology and ecological restoration in local, national and global contexts;
• Identify the environmental and biological controls on plant community composition and ecosystem structure;

• Relate habitat management to ecosystem function.
• At different scales, plan ecosystem creation or restoration based on the biotic and abiotic context of the area.
• Design and assess the feasibility and appropriateness of a habitat restoration scheme.

The control of water pollution and sedimentation needs to be based on the correct identification of source areas of sediment, a knowledge of the processes by which water and sediment are moved over the land surface, and an understanding of how these processes are affected by the physical environment and socio-economic factors.  Soil conservation can be achieved through within-field and catchment management by targeting erosion control measures at critical locations in the landscape, producing appropriate designs and gaining the support of interested groups and organisations for their implementation.

Human population growth and increased resource use per capita is placing unsustainable demands on the global ecosystem. This module explores sustainability using three approaches. The “Ecosystem Service” approach provides a framework for society to address key environmental issues such as food production, greenhouse gas emissions, biodiversity loss, and water use.  The “Circular Economy” approach refers to the development of “restorative” industrial systems that are grounded on the lessons of non-linear, feedback-rich ecosystems.  The third approach is to explore the nexus between renewable energy, food, and other ecosystem services using per capita energy and food consumption. This module introduces and critiques the three approaches and examines their application to resolve real-world problems and create commercial opportunities.

On successful completion of this module you should be able to:

• Critique the “ecosystem services”, “circular economy”, and “per capita energy use” approaches.

Improvement of land quality and the reclamation of degraded land are needed to ensure the sustainable delivery of ecosystem goods and services. Landscapes can be engineered to deliver these services by application of a base understanding of fundamental environmental properties and interrelationships of soil, vegetation and water. This understanding is grounded in basic soil physics, hydrology, hydraulics, geotechnics and agronomy. Land managers and engineers can design and implement appropriate land, water and vegetation management through interventions such as drainage, soil conservation, slope stabilisation and irrigation. This understanding and skills set are also the basis for management of projects involving land forming, reclamation, restoration and protection, which require selection, design, engineering and maintenance of appropriate structures.

Land planning and its "human dimension" are fundamental aspects of managing the physical and human environments.  Knowledge of and correct application of land planning methodologies and solutions is vital for sustainable management of what are often limited resources.  Management of the landscape requires evaluation of potentially many options. Constraints and opportunities are provided by the physical and human environment, and this module will highlight different methods that can be used to provide land resource planners with the data required to formulate sustainable plans. Often a range of options are possible and techniques to select optimum solutions will be covered.
