The grass family, known as Poaceae, is probably the most important plant family on earth. Grasses were the first food plants to be cultivated by man. Grass crops, such as maize, wheat, rice and sugarcane are still our most important food source to farm animals and the large herds of grazing animals in the wild. The identification of grasses becomes important during land management as the various grass species differ in their grazing value and other ecological functions. Furthermore, weedy grasses react differently to different herbicides and therefore need to be correctly identified. This title, Guide to grasses of southern Africa, is the most comprehensive colour identification guide to the common grasses of southern Africa and includes, among others, the following features: descriptions and illustrations of the 320 most important grasses in southern Africa, an easy-to-use grass identification key, more than 1 000 excellent photographs in full colour, thirteen short, fully illustrated introductory chapters with general information on grasses, common names of grasses in indigenous languages, icons that enable the reader to obtain certain information at a glance.
Faced with climate changes, pest pressure on plants is increasing
and new pest complexes are appearing, for which plant protection
solutions are not yet available. The reduction of anthropic
pressure on agroecosystems requires a reduction in the use of
chemical inputs and the promotion of biocontrol approaches. In this
book, we present new advances on plant disease management that are
emerging from research outputs. The ability of biocontrol products
to directly (e.g. production of antimicrobial peptides or quorum
quenching activities by microorganisms, use of plant or
agro-industrial by-products as biopesticides, etc.) or indirectly
(e.g. via the increase of plant defense or plant growth pathways)
protect plants against pathogens and pests is also considered. We
also address new strategies like the development of phage-based
biocontrol products and those that consider the plant as a
holobiont and plant microbiota as targets of biocontrol treatments.
The important question of the current regulatory process needed to
launch plant production products on the market is also addressed,
such as methods to evaluate their environmental impact.
'Roger Phillips has written the best mushroom book I know.' - Hugh
Fearnley-Whittingstall, author of River Cottage Veg Every Day! The
culmination of over thirty years' work, Roger Phillips's
authoritative and superbly illustrated reference work is packed
with information and original photographs. The essential
illustrated mycological encyclopedia, this book is also clear, user
friendly and will appeal to a wide range of readers. Unsurpassed in
both illustrative and descriptive detail, Mushrooms contains over
1,250 photographs, often showing the specimens in various stages of
growth, and includes all the latest botanical and common names as
well as current ecological information on endangered species.
Having sold more than 750,000 copies in Europe of his previous
title on mushrooms, Roger Phillips's Mushrooms once again sets the
benchmark. Quite simply, nobody with an interest in the subject can
afford to be without this book.
Plants provide the food, shelter, medicines, and biomass that
underlie sustainable life. One of the earliest and often overlooked
uses of plants is the production of smoke, dating to the time of
early hominid species. Plant-derived smoke has had an enormous
socio-economic impact throughout human history, being burned for
medicinal and recreational purposes, magico-religious ceremonies,
pest control, food preservation, and flavoring, perfumes, and
incense. In ten illustrated chapters, this global compendium
documents and describes approximately 2,000 global uses for over
1,400 plant species. The Uses and Abuses of Plant-Derived Smoke is
accessibly written and provides a wealth of information not only on
human uses, but also on conservation issues and the role of smoke,
fire, and heat in promoting seed germination in biodiversity hot
spots. Divided into nine main categories of use, the compendium
lists plant-derived smoke's the medicinal, historical, ceremonial,
ritual and recreational uses. Plant use in the production of
incense and to preserve and flavor foods and beverages is also
included. Each entry includes full binomial names and family, an
identification of the person who named the plant, as well as
numerous references to and other scholarly texts. Of particular
interest will be plants such as Tobacco (Nicotiana tabaccum),
Boswellia spp (frankincense), and Datura stramonium (smoked as a
treatment for asthma all over the world), all of which are
described in great detail. In addition, this is one of the first
ethnobotanical books to include a section on plant conservation. It
addresses issues of over-harvest and invasiveness, the two primary
conservation concerns with human-exploited species.
This book offers 10 'recipes' for Woodland adventures, each
structured around a story which is designed to capture the
imagination of 2-6 year olds. Each recipe provides parents and
carers with a list of the kit required (generally, simple household
objects) and a set of step by step instructions. A strong addition
to the successful Frances Lincoln creative parenting list, this
book focuses on activities for younger children, and connects with
the fast-growing Forest School movement.
Back in print just in time for spring! Originally published in
1948, this is the germinal text on nearly 250 species of spring
wildflowers found in West Virginia. Common or English names and
scientific or Latin names are given for each species. The
descriptions are in two sections: The first description includes
the meaning of the name of the flower, uses, habitats, and ranges
in West Virginia. Secondly, the plant itself is described in deep
detail to help in identification. Each description is accompanied
by a facing page detailed line drawing. This book is a must have
for those interested in the beauty and science of West Virginia's
spring flora.
Ireland, the Emerald Isle, is famous for its checkerboard landscape
of green fields and hedgerows. Its coast showcases sandy beaches,
mudflats and saltmarshes, Atlantic Rainforests, rocky shores and
cliffs, all home to a staggering variety of wildlife. Ireland's
coastal waters are among the best in Europe to see whales and
dolphins and other rare marine animals. The Crossbill Guide Ireland
is the authoritative wildlife and nature travel guidebook to that
island and includes both the Republic of Ireland and Northern
Ireland. The book provides insights into how this varied landscape
came into being with a description of its flora and fauna. The book
combines this background with carefully selected hiking and driving
routes that cover the best places to discover Ireland's wildlife
and ecosystems. If you want to explore Ireland's wild side, this is
the book you need.
Botanists and seed collectors Rod and Rachel Saunders set out on what seemed to some to be an impossible mission – to find and photograph, in full bloom, all gladioli species found in South Africa and to collect and share their observations in a field guide. They had found all but one species before their untimely deaths at the hands of kidnappers in a forest in KwaZulu-Natal.
In the wake of this tragic event, friends and colleagues collaborated to keep the Saunders’ dream alive. This book is the result their collective efforts.
Gladioli are showy bulbous plants that fall within the Iris family, and the bulk of species are endemic to South Africa. Comprehensive and lavishly illustrated with more than 1,300 photographs, this guide covers the 166 Gladiolus species known to occur in the region.
The book is divided into seven taxonomic sections, according to the species’ distinguishing features. Each species is presented on a double-page spread, with a full plate of color photographs, including close-ups of diagnostic features, different color forms and habitats. Botanical descriptions cover identification (corm, cataphyll, spike, bracts, anthers, pollen, capsules, seeds, and scent), distribution, pollination, conservation status, and notes on ecology and the authors’ personal observations in the field. Distribution maps and flowering periods are given for each species, and tables highlight differences between similar-looking gladioli.
There are almost 300 recognized species, widely distributed across Africa, Europe and the Middle East, with more than half of the species found in southern Africa, making this book useful to botanists world-wide, as well as to horticulturist, propagators, students, gardeners and anyone with an interest in natural history.
