A HANDBOOK FOR EUCALYPTUS PLANTERS. INTRODUCTION. The growing interest in forest planting in California makes it desirable that prospective planters be supplied with concise information regarding the demands and qualities of the genus Eucalyptus, which, owing to its rapid growth and wide adaptation to economic uses, is destined to be planted more extensively than any other tree. Reliable information on this genus is now obtainable in Bulletin No. 35 of the Forest Service, but the information contained is more general in nature than the typical, quick-action planter is willing to digest. More recently a detailed, though as yet unpublished, report on the planting of the commercial eucalypts has been made by S. J. Flintham of the Forest Service after a study conducted in coöperation with the State of California. The essentials for planters have been culled from this report and other sources and embodied in this circular to meet the great demand for specific information on the economies of Eucalyptus planting. HISTORY OF EUCALYPTUS IN CALIFORNIA. The eucalypts are exotics in California, having been introduced from Australia in the early fifties by travelers who were impressed with the splendid proportions and rapid development of the genus in its native habitat. They were first planted in the vicinity of San Francisco for ornamental purposes. Later, in the sixties, they were planted near Los Angeles. The rapid growth and complete adaptability of the exotic to its new environments instantly claimed the attention of nurserymen, who recognized its suitability for commercial planting. Between 1870 and 1875 considerable planting was done for fuel, windbreaks and shade along avenues. One of these early groves was established near Irvington in the Santa Clara Valley in 1870, and later, 1872 and 1873, the first plantation in Southern California was made by Hon. Ellwood Cooper on his ranch near Santa Barbara. The well-known Widney and Nadeau groves, set out in 1874 and 1875, were the first extensive plantations made near Los Angeles. THE TIMBER EUCALYPTS. Eucalyptus has deservedly claimed more attention than any other exotic genus, and probably more than most of those indigenous to the United States. Great energy and persistence in experimenting with |
