Indian forests are covered with teak plantations, low in biodiversity and seasonally ravaged by forest fires. The first foresters in India were highly influenced by forest management in Germany and many forest officers in India were trained in the German school of thought brought into India by Dietrich Brandis (1824–1907)-the father of tropical forestry. Numerous officers including James Sykes Gamble (1847–1925), Alexander Gibson and Hugh Francis Cleghorn in the Indian Forest service added information on the flora of India. Several amateurs also worked alongside from other civil services and they were assisted by professional botanists such as Joseph Dalton Hooker (1817–1911), John Gerard Koenig (1728–1785), Robert Wight (1796–1872), Nathaniel Wallich (1786–1854) and William Roxburgh (1751–1815), the Father of Indian Botany. Another area of interest was the introduction of plants of economic importance to India. Many of these introductions were tried in botanical gardens at Sibpur, Poona, Madras and Saharanpur. The Chinese monopoly on tea was ended when tea was introduced in Darjeeling and Sri Lanka through the work of Robert Fortune (1812–1880). The botanical garden at Sibpur in Calcutta was started in 1787 by Col. Robert Kyd (1746–1793). Sir George King (1840–1904) who was in charge of the garden from 1871 was instrumental in the creation of a herbarium at the garden and founded the Botanical Survey of India in 1890. Later botanical workers include the paleobotanist Birbal Sahni (1891–1949). Some of the other prominent names associated with botany and forests of India include William Carey (1761–1834), Sir Henry Collett (1836–1901), Ethelbert Blatter (1877—1934), T. F. Bourdillon, Sir Harry Champion and his brother F. W. Champion (1893–1970), A. A. Dunbar-Brander (Conservator of Forests in the Central Provinces), Sir Walter Elliot (1803–1887), Henry Thomas Colebrooke (1765–1837), Charles McCann (1899–1980), Hugh Falconer( 1808–1865), Philip Furley Fyson (1877–1947), Lt. Col. Heber Drury, William Griffith (1810–1845), Sir David Prain (1857–1944), J. F. Duthie, P. D. Stracey, Richard Strachey (1817–1908), Thomas Thomson (1817–1878), J. E. Winterbottom, W. Moorcroft and J.F. Royle (1799–1858). Naturalists associated with the Bombay Natural History Society like W. S. Millard (1864–1952) helped popularise the study of trees with books such as Some Beautiful Indian Trees (coauthored with Ethelbert Blatter). Similar attempts were made by civil servants like Alexander Kyd Nairne in his Flowering plants of Western India (1894). Several herbaria were created during this time and one of the largest and still surviving ones is the Blatter Herbarium. Hunter-naturalists Hunting was
