Conservation heating has become the main method of controlling relative humidity in historic houses of the National Trust and many other organizations. In recent years the Trust has begun to focus on its carbon footprint and ways that it can use energy more efficiently in all its activities. This article describes work the Trust is undertaking to evaluate energy use of its conservation heating systems. The research focuses on three case study properties to understand their conservation heating energyuseinterms ofthespacescontrolledandto comparetheir efficiencies with external benchmarks. The article further describes the development, testing and application of 'conservation heating degree days' as a method for estimating the energy demand of conservation heating systems from simple environmental data.

A qualitative understanding of the particles in dust and their sources helps to identify ways to reduce the accumulation of dust within historic houses. Knowing the possible sources of dust helps to suggest preventive steps. Simple low-technology methods enable rapid identification of dust deposits and require little specialist equipment. Dust samples can be collected on sticky surfaces for examination with a hand lens or microscope. The size of particles and fibres, and amount of surface coverage, can be estimated roughly using a graticule or coverage chart. An atlas of common dust components aids identification of soil dust, soot, insects, plant fragments, hair, skin, paint/plaster, clothing fibres, paper, food and mould. A mixture of fine dust is resolvable into a range of particle and fibre types. Long exposures of sticky samplers, with an estimate of the area covered by dust, indicate the rate of deposition and suggest the cleaning frequency necessary to prevent negative visitor reactions. The atlas lists suppliers and sources of information.

How do organizations navigate change and remain viable for the future while remaining true to their core purpose? The National Trust's development of its Conservation Principles in 2008 was in response to the continuing need to rearticulate its purpose and vision in a changing socio-economic climate. They take account of the principles and charters produced by national and international conservation organizations. In fact, their timing serendipitously reflected the publication of those of English Heritage. This article is by one of the authors chiefly responsible for producing the Conservation Principles, working alongside the full range of conservation professionals involved in the National Trust's work. It explains how one set of principles can encompass butterflies and books, farms and furniture, coast and country houses. It will discuss how the Trust is developing the use of these principles to help the non-conservation specialists who manage our properties take decisions that are well founded not only in improving conservation and the environment, but which also address other sustainability factors to provide finance and social benefits, in particular through the way that conservation and access need to be considered as mutually beneficial rather than in conflict.

Ecological restoration frequently involves setting fixed species or habitat targets to be achieved by prescribed restoration activities or through natural processes. Where no reference systems exist for defining outcomes or where restoration is planned on a large spatial scale, a more 'open-ended' approach to defining outcomes may be appropriate. Such approaches require changes to the definition of goals and the design of monitoring and evaluation activities. We suggest that in open-ended projects restoration goals should be framed in terms of promoting natural processes, mobile landscape mosaics and improved ecosystem services. Monitoring can then focus on the biophysical processes that underpin the development of habitat mosaics and the provision of ecosystem services, on the way habitat mosaics change through time and on species that can indicate the changing landscape attributes of connectivity and scale. Stakeholder response should be monitored since an open-ended restoration approach is unusual and can encounter institutional and societal constraints. Evaluation should focus on reporting changing restoration impacts and benefits rather than on achieving a pre-defined concept of ecological success. © 2011 Elsevier GmbH.

There is an increased appreciation of the need for horizon scanning: the identification and assessment of issues that could be serious in the future but have currently attracted little attention. However, a process is lacking to identify appropriate responses by policy makers and practitioners. We thus suggest a process and trial its applicability. Twelve environmental conservation organizations assessed each of 15 previously identified horizon scanning issues for their impact upon their organization and the urgency with which they should consider the issue. They also identified triggers that would result in changes in their scoring of the likely urgency and impact of the issues. This process enables organizations to identify priority issues, identify issues they can ignore until there are further developments, benchmark priorities across organizations and identify cross-organizational priorities that warrant further attention, so providing an agenda for collation of evidence, research and policy development. In this trial the review of responses by other organizations resulted in the upgrading of response by a substantial proportion of organizations for eight of the 15 issues examined. We suggest this approach, with the novel components of collaborative assessment and identification of triggers, could be adopted widely, both within conservation organizations and across a wider range of policy issues. © 2012 Fauna & Flora International.
