hills, which he visited in 1879, the Devarakadus of Coorg in 1868, the hill ranges of the Salem district in the Madras Presidency in 1882, the Swami Shola on the Yelagiris, the sacred grove at Pudur on the Javadis and several sacred forests on the Shevaroys. He was among the earliest in India to formally link forest protection with local peoples. He also took an interest in the forest flora of northwest and central India and of Indian trees in general. Even after retirement, Brandis continued to work on Indian forestry, and at the age of 75, he started his principal botanical work, Indian Trees, dealing with 4400 species. It was first published in 1906 and re-issued several times afterwards, the last time in 1971. He was posted at Balaghat in M.P. as a principal of forester training institute for a long time in his service period. Retirement After his retirement from the position as Inspector General of Forests in India in 1883, he returned to Bonn, but frequently visited England in the following years. From 1900 until 1906 he lived permanently in Kew in Greater London. He also supervised training of forestry students at the Royal Indian Engineering College in England for eight years (1888–1896). His interest in American affairs led him to take special care of American foresters visiting Europe, for which he received a personal letter of thanks by President Theodore Roosevelt in 1904. He was succeeded as Inspector General of Forests by Lt Col Frederick Bailey of the Royal Engineers. Shortly after returning to Bonn in late 1906, he was hospitalized and died a few months later on 28 May 1907. Broader influence Brandis was also involved in forestry education in England at Coopers' Hill. He also influenced and mentored many like Berthold Ribbentrop, W. Schlich and C.A. Schenck of Germany (while a visiting professor at the University of Giessen), and Gifford Pinchot and Henry Graves (the first and second chiefs of the USDA Forest Service) of the United States. He influenced the forestry movement in the United States by mentoring Pinchot, Graves, and others who came to study with him in Germany, and through his voluminous correspondence with many other men, such as Charles Sprague Sargent and Franklin Hough involved in establishing the U.S. national forest system. Pinchot relied heavily upon Brandis' advice for introducing professional forest management in the U.S. and on how to
