Review of \u3ci\u3e620 Wild Plants of North America: Fully Illustrated.\u3c/i\u3e By Tom Reaume.

Beautifully and profusely illustrated with the author\u27s black-and-white drawings, the 12-year project that became this book shows his love for plants. Tom Reaume focuses on a representative selection of primarily native vascular plants of the Great Plains of Canada and the northern United States found in forests, lakes, prairies, rivers, and wetlands. The book appears to be designed as a supplement for an introductory course in plant taxonomy. This book is a useful reference for those interested in the flora of the northern Great Plains and adjacent regions. I highly recommend it for college and university libraries where botany and biological illustration classes are taught on campus. The accurate, beautiful, and profuse illustrations are worth the price of the book by themselves

Floristic Composition and Conservation Status of Fens in Iowa

Over 200 extant fens of varying condition were documented during an extensive inventory conducted in Iowa between 1986 and 1991. Approximately half of the extant fens support endangered, threatened, special concern, or other rare plant species. Approximately 25 fens are outstanding conservation prospects with intact vegetation, high species richness, and rare species. Nearly 40% of all potential fen sites have been destroyed by cultivation or damage; another 30% remain unknown due to lack of a field visit, but most appear on aerial photographs to be very small, disturbed fragments. In addition to their traditionally recognized range in northwest Iowa, fens were found to be numerous and widespread in eastern Iowa. Most (95%) of the extant fens occurred on private lands; these were variously affected by grazing (65%), cropfield edge effects (33%), potential expansion of woody plants (20% ), drainage by tile lines or ditches (10% ), excavation for ponds (2%), and mining of nearby sand and gravel deposits (2%)
