"Between 1989 and 2012, three Forest Service programs collected more than 8,300 surveys of epiphytic lichen communities, providing a baseline for tracking lichen responses to air quality, climate, and other changes on forest land in the United States. This national atlas of lichen species combines these datasets into distribution maps for more than 400 taxa and 6,000 forested locations across the country. All 115,500 lichen records presented in the maps link to voucher specimens, most of which can be accessed from herbaria. Unlike mapped herbarium records, most surveys were collected on a systematic national grid. Therefore, the absence of a species at a particular location can indicate meaningful information about its geographic distribution. Facets of the survey protocol, however, likely lead to the underrepresentation of rare, cryptic, and otherwise easily overlooked species in the dataset. Each species search lasted 2 hours, covering a nearly 1-a area in which surveyors aimed to capture all epiphytic macrolichens. Surveyors possessed various skill levels but underwent annual training, certification, and field audits by professional lichenologists. During the 23 years of data collection, many lichen names and species concepts have changed. This atlas dataset is the first to unite all records across the three parent programs by using a consistent taxonomic treatment. In some cases, maps represent "lumped" taxa or show only records from restricted timeframes. The species distribution maps, Atlas dataset, and tools for designing custom datasets are published online at https://www.fia.fs.fed.us/program-features/indicators/lichen."

A comprehensive, up-to-date review of lichens as biomonitors of air pollution (bioindication, metal and radionuclide accumulation, biomarkers), and as monitors of environmental change (including global climate change and biodiversity loss) in a wide array of terrestrial habitats. Several methods for using lichens as biomonitors are described in a special section of the book.

How do you record the wildlife in a wood? This book explains ways to record the flora and fauna found in woodland and outlines the sources you can use to find out more about the history and management of an area. Whether you have just a few hours, or a few years, there are examples that you can follow to find out more about this important habitat. Woods include some of the richest terrestrial wildlife sites in Britain, but some are under threat and many are neglected, such that they are not as rich as they might be. If we are to protect them or increase their diversity we need first to know what species they contain, how they have come to be as they are, to understand how they fit into the wider landscape. Conservation surveys are the bedrock on which subsequent protection and management action is based. There is not one method that will be right for all situations and needs, so the methods discussed range from what one can find out online, to what can be seen on a general walk round a wood, to the insights that can come from more detailed survey and monitoring approaches. Fast-evolving techniques such as eDNA surveys and the use of LiDAR are touched on.

Lichens are highly valued ecological indicators known for their sensitivity to a wide variety of environmental stressors like air quality and climate change. This report summarizes baseline results from the U.S. Department of Agriculture, Forest Service, Forest Inventory and Analysis (FIA) Lichen Community Indicator covering the first full cycle of data collection (1998-2001, 2003) for Washington, Oregon, and California. During this period, FIA conducted 972 surveys of epiphytic macrolichen communities for monitoring both spatial and long-term temporal trends in forest health. Major research findings are presented with emphasis on lichen biodiversity as well as bioindication of air quality and climate. Considerable effort is devoted to mapping geographic patterns and defining lichen indicator species suitable for estimating air quality and climate.

In the mid 1970s two events led me to get to know the Yorkshire Dales better than I had previously. Since 1964 I had been to the Malham Tarn Field Centre with groups of students, first from the University of Edinburgh and then from the University of York, and my family very much enjoyed the summer days we spent amid this magnificent hill scenery. In 1976, the British Ecological Society and the National Trust jointly worked on a survey of the biological interest of the National Trust properties of the Kent, East Anglian and Yorkshire Regions. Malham Tarn itself, and the surrounding farms, formed one of the twenty properties of the Yorkshire Region. I spent the bank holiday, that commemorated the Queen's Silver Jubilee, at Malham, looking fairly closely at the National Trust's landholding there. Miss Sarah Priest, who also looked at the National Trust properties, and I produced a report in late 1977, attempting both to describe and to evaluate the nature resources of the National Trust in Yorkshire. In the following year, 1978, the Nature Conservancy Council wanted to survey the whole of the upland area that was known as the Malhaml Arncliffe SSSI (Site of Special Scientific Interest). A contract to look at such an exciting area, considering where boundaries should go, and looking to see if there were important areas of habitat that should be brought within the SSSI, was a superb practical antidote to an office in the University.

In this comprehensive book, the critical components of the European landscape - forest, parkland, and other grazed landscapes with trees are addressed. The book considers the history of grazed treed landscapes, of large grazing herbivores in Europe, and the implications of the past in shaping our environment today and in the future. Debates on the types of anciently grazed landscapes in Europe, and what they tell us about past and present ecology, have been especially topical and controversial recently. This treatment brings the current discussions and the latest research to a much wider audience. The book breaks new ground in broadening the scope of wood-pasture and woodland research to address sites and ecologies that have previously been overlooked but which hold potential keys to understanding landscape dynamics. Eminent contributors, including Oliver Rackham and Frans Vera, present a text which addresses the importance of history in understanding the past landscape, and the relevance of historical ecology and landscape studies in providing a future vision.

Periodic comprehensive overviews of the status of the diverse organisms that make up wildlife are essential to determining trends, threats and future prospects. Just over 25 years ago, leading authorities on different kinds of wildlife came together to prepare an assessment of their status of a wide range of organisms in Great Britain and Ireland i
