Nature artist Jane Smith has been fascinated by wildlife communities and ecosystems her whole adult life. Starting from her own garden in Argyll, she travels to ten locations in the west of Scotland - from the towering cliffs of St Kilda and the peatlands of Lewis to the Solway estuary and the urban sprawl of Glasgow - to explore the interaction of people and wildlife in a variety of diverse settings. On her journey she discovers a number of communities who are taking on the job of regenerating their own landscapes and meets a host of fascinating people whose lives are inextricably bound up with questions of sustainability, conservation and landownership. Contents Includes: Western Isles (peatlands) * North Uist (machair) * Islay (farmland) * Loch Arkaig (woodland) * Knapdale (wetland) * Dumfries and Galloway (river and estuary) * Jura (coast) * St Kilda archipelago (sea) * Glasgow (urban landscapes) *Eigg (community ownership)

The banana is the most eaten fruit in the world but its future is under threat. World expert Professor James Dale contemplates how well save the humble banana in this fascinating edition to the FUTURES Series.The bananas that we see in our supermarkets, eat for breakfast and blend into our smoothies are facing possible extinction. First cultivated thousands of years in ago in the tropics of Southeast Asia, the banana has become the most eaten fruit in the world, with the lucrative banana industry resulting in political coups, drug trafficking and even murder.While there are thousands of banana varieties, only one has become the western worlds favourite the Cavendish: our familiar curvy, yellow-skinned, soft-fleshed fruit. But our obsession with the Cavendish has come at a cost. Years of selective breeding to produce the fruit we love, and humankinds migration across the world has left the Cavendish susceptible to disease and climate change so much so that in years to come they may face extinction. How can we save the future of the banana?Professor James Dale is leading the way in banana research. Based at Queensland University of Technology in Australia, he and his team have developed the QCAV-4 banana the worlds first genetically modified banana to be approved for commercial production. In the book he presents many scenarios that could be used to save the Cavendish based on the latest research and technological developments, from gene editing, cisgenics, AI design and biofortifiction, all the while bringing to life the colourful history of the banana.Bananageddon can be prevented, he argues, if the world is ready to embrace a new future led by scientific change.

After working as a botanist and natural historian for more than 25 years, walking the countryside had almost imperceptibly turned into a disheartening endeavour for Pete Stroh. He found himself resting at viewpoints and contemplating how much better it would be if a pasture had not been drenched with herbicide, if a woodland had not been planted up with regimented lines of conifer crops, if an arable field could every so often not be ploughed right up to the bloody roots of the hedgerowSo he decided that in writing this book, he would wander within the boundaries of the parish where he lives, record weekly what he actually saw, and restrict grumblings to a minimum, to observe rather than judge. This, he writes, took a bit of getting used to but proved ultimately to be a liberating and unexpected experience.The result is this uplifting and positive book showing the surprising abundance of nature, given half a chance.

The Natural History of Selborne (1789) assembles Gilbert Whites decades of field notes into an epistolary chronicle addressed to fellow naturalists Thomas Pennant and Daines Barrington. Through lucid, quietly lyrical prose, White records the seasonal pulse of a single English parishits birds, insects, plants, soils, and weathermarrying patient empiricism with pastoral attentiveness. His long-term observations on swallow migration, the habits of earthworms, and the harvest mouse exemplify a proto-ecological method grounded in place. Situated within Enlightenment natural history, the book helped pivot the discipline toward attentive, longitudinal, local study. A country clergyman educated at Oxford, White spent most of his life in Selborne, Hampshire, ministering to his parish while tending gardens and keeping meticulous journals. His correspondence with leading savants, daily walks and weather logs, and deep familiarity with the Hanger and Common fostered a modest, exact observer whose theology of creation harmonized with Enlightenment curiosity. Readers of natural history, Romantic literature, and environmental studies will find this classic both foundational and unexpectedly contemporary: a masterclass in noticing. For anyone seeking rigorous, humane observation and the pleasures of place-based inquiry, Selborne remains an indispensable companion in an age of ecological uncertainty.Quickie Classics summarizes timeless works with precision, preserving the authors voice and keeping the prose clear, fast, and readabledistilled, never diluted.

In Pursuit of Spring (1913) follows Edward Thomass bicycle ride from London to the Quantock Hills of Somerset as winter loosens. In lucid, finely cadenced prose, he records lanes, hedgerows, inns, birdsong, weather, and place-names, blending topographical exactitude with lyrical restraint. Set within the English peripatetic tradition of Cobbett, Borrow, and Jefferies, the book also registers the modernroads, telegraph wires, the bicycle itselfwith poised ambivalence, reading the countryside as both archive and living present. Thomas (18781917), a London-born critic of Welsh parentage, had long written about the countryside while burdened by hackwork. Walking and cycling were his release; soon after this journey, friendship with Robert Frost would usher his turn to poetry. His love of maps and place-names, and his minute knowledge of birds and rural labor, shape the books inquiry into language, memory, and belonging. For readers of nature writing, travel literature, and the environmental humanities, this is a quietly bracing companion: attentive, unsentimental, and restorative. Whether cyclist, walker, or armchair traveler, you will find a luminous meditation on how to see a landscape in time, and why such seeing matters.Quickie Classics summarizes timeless works with precision, preserving the authors voice and keeping the prose clear, fast, and readabledistilled, never diluted.

In The Mountains of California, John Muir fuses lyrical reverie with scrupulous natural history to chart the Sierra Nevadas glaciers, forests, cascades, and high meadows. In late nineteenthcentury American nature writings Emersonian current, he advances a glacial account of Yosemite while recording flora, fauna, weather, and rock with exacting taxonomy. The original illustrations extend his itineraries and anchor the books vivid, field-born essays. MuirScottish-born immigrant, itinerant inventor, and later Sierra Club cofounderdrew these chapters from seasons of herding, botanizing, and snow-camping in the high country between 1869 and the early 1870s; the book appeared in 1894. An eye injury, a thousand-mile walk, and settlement in California refined his vocation for attentive wandering. Journals, lectures, and geological debate converge here, shaping a conservation ethic grounded in minute empirical seeing. This edition rewards readers of environmental history, geology, and American letters as well as hikers seeking a field companion. It offers a lucid synthesis of science and rapture, and, with its period plates, a portal into the formative imagination behind Americas national parks.Quickie Classics summarizes timeless works with precision, preserving the authors voice and keeping the prose clear, fast, and readabledistilled, never diluted.
