Vascular Plants of the Intermountain Region (U.S.A.)

美国西部山间地区的维管束植物区系图解正在准备中，必要时提供描述、完整的同义词和注释。《山间植物志》是一本六卷本的丛书，讲述了由犹他州、几乎整个内华达州、南爱达荷州、俄勒冈州东南部以及怀俄明州、加利福尼亚州和亚利桑那州的一小部分组成的自然植物区系。已经完成了五卷。最后一卷已经开始，将在拟议的三年内完成。准备《植物志》需要对野外和标本馆中的植物进行广泛的研究，还需要进行彻底的书目调查。除了其固有的科学价值外，《山间植物志》在编制与该区域可能的采矿或其他工业发展有关的环境影响声明方面具有极其重要的作用，也是关于受威胁和濒危物种的信息来源。为林务局、土地管理局、鱼类和野生动物管理局以及国家公园管理局工作的土地管理人员也发现，山间植物是不可或缺的。

An illustrated vascular flora of the Intermountain Region of western United State is being prepared with descriptions, full synonymy, and commentary as necessary. The Intermountain Flora is a six-volume series treating the natural floristic region consisting of Utah, nearly all of Nevada, Southern Idaho, Southeastern Oregon, and small parts of Wyoming, California, and Arizona. Five volumes have been completed. The final volume has been begun and will be completed in the proposed three years. Preparation of the Flora entails extensive study of the plants in the field as well as in the herbarium, and also requires a thorough bibliographic inquiry. Aside from its intrinsic scientific interest, Intermountain Flora is of fundamental importance in the preparation of environmental impact statements in connection with possible mining or other industrial development in the region, and is a source of information on threatened and endangered species. Land managers working for the Forest Service, Bureau of Land Management, Fish and Wildlife Service, and National Park Service also find Intermountain Flora indispensable.
