Larger animals can be voracious and undiscriminating grazers of plants. In the wild these can range from the smallest mice to the largest elephants of africa. Gardeners are extremely unlikely to come across anything nearly as large as an elephant, which can only be a blessing as they can be extremely destructive in their search for food, uprooting entire trees in order to get to their nutritious parts.
rabbits feed on a very wide range of ornamental plants, fruit, and vegetables and can easily cause sufficient damage to kill herbaceous plants, shrubs, and young trees. They can even ringbark mature trees. new plantings and soft growth in spring are most Tanacetum coccineum,

ames sowerby was an english naturalist, engraver, illustrator, and art historian. over the course of his lifetime, he singlehandedly illustrated and cataloged thousands of species of plants, animals, fungi, and minerals of Great britain and australia.sowerby enjoyed a dual career, achieving distinc- tion both as an outstanding artist and as a keen scientist. He bridged the gap between art and science, working closely with botanists to make his drawings as accurate and as scientific as possible. His main aim was always to bring the natural world to a wider audience of gardeners and nature lovers.
He was born in London and, having decided to become a painter of flowers, studied art at the royal academy. He had three sons—James De Carle sowerby, George brettingham sowerby I, and Charles edward sowerby, who all followed their father’s work and became known as the sowerby family of naturalists. His sons and grandsons continued and contributed to the enormous volumes of work he began and the sowerby name remains firmly associated with illustrations of natural history.
sowerby’s first venture into botanical illustration was with William Curtis, Director of the Chelsea Physic Garden, London, and he illustrated both Flora Londinensis and Curtis’s Botanical Magazine—the first botanical journal published in england. sowerby created as well as engraved the illustrations, seventy of which were used in the first four volumes. This and an early commission from the botanist L’Héritier de brutelle to provide the floral illustrations for his large work on the Geranium family, Geranologia, and two later works, helped lead to sowerby’s prominence in the field of botanical illustration.
A Specimen of the Botany of New Holland, written by James edward smith, was both illustrated and published by sowerby, and was the first mono- graph on the flora of australia. It was prefaced with the intention of meeting the general interest in, and propagation of, the flowering species of the new antipodean colonies, but also contained a Latin botanical description of the plant samples. sowerby’s hand-colored engravings, based upon original sketches and specimens brought to england, were both descriptive and striking in their beauty and accuracy. This use of vivid color and accessible texts was the beginning of sowerby’s over-arching intention to reach as wide as audience as possible with works of natural history.
at the age of thirty-three, sowerby began the first of several huge projects—a thirty-six-volume work on the botany of england, English Botany or Coloured Figures of British Plants, with their Essential Characters, James sowerby illustrated thousands of species
of plants and fungi. He worked with scientists to produce careful and meticulous work.

Synonyms and Places of Growth. This was published over the next twenty-four years, contained 2,592 hand-colored engravings, including numerous plants receiving their first formal publication, and became known as Sowerby’s Botany.
Unlike other flower painters of the time, whose work tended toward pleasing wealthy patrons, sowerby worked directly with scientists. His meticulous description of the subjects, drawing from specimens and research, was in direct contrast to the flower paintings of the rococo period found illuminating the books of that time. The appealing hand-colored engravings, usually sketched quickly in pencil, became highly valued by researchers into new fields of science.
His next project was on a similarly huge scale— The Mineral Conchology of Great Britain, which was a comprehensive catalog of invertebrate fossils of england. This was published over thiry-four years,
latterly by his sons James and George. He also developed a theory of color and published two landmark illustrated works on mineralogy: British Mineralogy and its supplement, Exotic Mineralogy. Having such a scientific disposition, sowerby retained as many of the specimens used in his work as possible. a comprehensive collection of his work is maintained at the natural History Museum in London. It includes his drawings and specimen collection for English Botany, approximately 5,000 items from his fossil collection, and a large collection of his personal correspondence. further work is held by the Linnean society of London.

Careful illustrations of fungi, mushrooms, and toadstools were just one of sowerby’s specialities.

recycling, particularly in the soil. other fungi may be parasitic on plants (or animals); many of these are serious diseases of cereal crops, or have a less damaging symbiotic relationship, such as those that form mycorrhizal associations (see p.56). The group of fungi known as truffles are mycorrhizal, associated with the roots of trees like beech, hazel, birch, and hornbeam.
