Book excerpt: Biodiversity, during the past few years, has become a 'buzz' word, as if this were a brand new concept. The word appears in the news, on television, in advertising, in grant proposals, particularly for tropical studies because it is in the tropics that the terrifyingly rapid extinction of plant and animal species and their ecosystems are threatening the earth's ecology. Hundreds of species are being exterminated before they become known to science. The natural history repositories themselves, especially those housing the primary collections of a region or major political unit, have much to answer for in this crisis for not articulating their importance and value to research. It has been our aim at the University of Colorado Museum to provide catalogues and regional taxonomic handbooks in order to develop a literate public and to increase the value of the collections to amateur and professional students of the flora and fauna.

Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Flora of Colorado The author has tried to verify the records referring to Colorado plants given in these publications. Some of these records have been proven erroneous. In some cases the specimens were wrongly determined, in others the stations at which they were collcted are not within the present boundaries of the state of Colorado. Of course, all such species have been excluded from this catalogue. The author has also excluded a few more, which he thought should be included in the same category, although he has not been able to prove them erroneously referred to the flora of Colorado, as for instance Californian, Mexican, or Alleghanian species, accredited to Colorado but not to the intervening states. He has also been forced by circumstances to exclude a score or so species recently described from Colorado, but wholly unknown to the author. Not being able to include them in his keys and being uncertain whether the descriptions really characterize new and valid species or merely represent redescriptions of old ones, he thought it best to leave them out until more information could be had.

Book excerpt: Excerpt from Flora of Colorado It was not the original intention of the Experiment Station to prepare and publish a work on the Flora of Colorado. The conditions of the State, the character of the flora, which is so different from that of the east, forced the necessity of collections and the study of local flora by the botanists of the Agricultural College and Experiment Station from the very first. The economic study of Colorado plants, especially the search for those which might be adapted to arid conditions, increased this necessity. Opportunity was furnished by collections of grasses and forest products for the Worlds Fair, and occasion was always taken when trips were made for any purpose, to obtain additional specimens. In the course of time the collection became so extensive that unless put in form for publication the time and expense involved would be lost, and the work which had been done would be of little service to us, and of none to the public in general. Some systematic collection was done by Professor James Cassidy, Professor of Botany (1881-1889), in the intervals of his many duties, up to the time of his death in 1889. His successor, Professor C. S. Crandall, gave much time to the work, especially after the establishment of the experimental grass station in cooperation with the U. S. Department of Agriculture. This afforded occasion and opportunity for trips in search of promising species of native grasses. Subsequent collections, especially of forest products and grasses for the World's Fair in 1893, gave rise to further collecting trips to various parts of the State. Enthusiastic aid was given by Mr. J. H. Cowan, an energetic and promising student, who became Professor of Horticulture and Botany upon the resignation of Professor Crandall, but whose promising career was terminated by death before he had entered upon the active duties of the position. By this time the collection was of considerable size, had been increased by exchanges, and represented much time and expense. A great many calls came for information, and it was at first thought to publish only a list of the plants which were represented in our own collection.
