. . dedicated to the appreciation and conservation of the Colorado native flora” Volume 30 Number 3 ANNUAL MEETING EDITION June - July 2006 2006 ANNUAL MEETING THE ARKANSAS BASIN AND BEYOND: 10,000 FEET OF FLORA September 8-10, Colorado Springs The Southeast Chapter invites CONPS members to attend the annual meeting on the campus of the University of Colorado at Colorado Springs (UCCS), September 8- 10, 2006. The theme of the meeting is the unique flora of southeastern Colorado. Those unfamiliar with the flora of this region may not realize that south- eastern Colorado has species in common with southern and east- ern states. Plant associations in this region can be considerably different from those in northern and western Colorado or as Jack Carter says "flora doesn't recognize state boundaries." The Rare Plant Technical Committee will meet on Friday; and Friday evening we will have a summary of the RPTC, a program on regional geology and a social hour. The Saturday programs are about the regional flora, concluding with a campus field trip start- ing at the meeting room door. Three field trips of limited size are scheduled for Sunday September 10. The trips choices are 1) the shortgrass prairie of the Chico Basin Ranch, 2) the foothills ecosystem of Aiken Canyon Preserve; or 3) the Pikes Peak Alpine Laboratory Ruins accessed from the Manitou and Pikes Peak Cog Railway. Reservations for Luncheon and Field Trips To reserve your place at the Saturday luncheon banquet and at the field trips please sign up and remit your check by August 22, 2006. To reserve space at the buffet luncheon Saturday September 9, pay $12 per person in advance prior to August 22. Late registrants can sign up later, but will not be able to attend the banquets. Parking Parking on campus has been arranged for free ONLY in Lots 3 and 4 for Friday Sept 8 from 8:30 am- 9:30 pm. There is no charge or permit required for Saturday Sept. 9. Park in parking lot 3 or 4 only to avoid fines. Alternatively, one can pay at the visi- tor parking garage Level 3. The Southeast Chapter is looking forward to hosting the meeting on this lovely campus and invites all interested members to attend. On the thirtieth anniversary of our organization, come and experience the vitality of our botanical community.

The RPTC is an ad-hoc group of agency and NGO botanists that has been working for years to advance rare plant efforts in the state. Your personal knowledge of Colorado field botany makes your contribution to this effort critical. The RPTC will select approximately 20 globally imperiled (G2) species known from southeastern Colorado for discussion of their current status and potential threats, as well as present highlights from last years symposium. The symposium is open to any one with an interest in the rare plants of southeastern Colorado. Contact Jill Handwerk for more information at jhand@lamar.colostate.edu or 970-491- 5857.

From 2000 to 2002, I examined the effects of the blowdown and salvage-logging disturbances on 1) tree seedling regeneration dynamics, 2) under- story vegetation composition and cover, and 3) nutrient cycling and ecosystem processes. In terms of seedling regeneration dynam- ics, results show little evidence of new seedling establishment in either blowdown or salvage-logged areas, confirming the results of prior studies in Colorado sub- alpine forests that show that advanced regeneration of previously suppressed understory seedlings is the primary mech- anism of regeneration in wind-disturbed subalpine ecosystems. Density of residual seedlings, particularly Engelmann spruce seedling density, was severely reduced in salvage-logged areas. Subsurface soil tem- peratures routinely exceeded 32 degrees C during the growing season in salvage- logged areas, and may have induced phys- iological shock in residual seedlings. Seedlings in blowdown areas showed enhanced growth rates in the period fol- lowing the 1997 blowdown but otherwise did not differ significantly in their density or composition from seedlings in control stands. Seedling growth rates since the blowdown were most closely related to the biomass of woody debris, which may indi- cate the importance of woody debris in moderating temperature and light avail- ability in a manner that favors seedling growth. These results suggest salvage-logging fol- lowing catastrophic wind disturbance dis- rupts the advanced regeneration processes that ensue following wind disturbance in subalpine forest ecosystems. If new seedling establishment remains low over time, salvage-logged areas with extremely low residual seedling densities may transi- tion from a spruce-fir dominated ecosys- tem to a subalpine meadow. Studies of the composition, cover and diversity of understory plants revealed that understory species cover and diversity were greater in blown down areas than in salvage-logged or control areas. At a land- scape level, the blowdown added 15 species to the assemblage found in intact spruce-fir forest, whereas salvage-logging only added two species not found in the other treatments, one of which, Spegularia rubra, is non-native. From a landscape perspective, the blowdown disturbance helps maintain understory diversity, while initially salvage logging does not con- tribute significantly to understory diversi- ty. Blowdown areas experienced an increase in cover of early successional species that thrive in disturbed areas, such as Rubus idaeus, Chamerion danielsii and Distegia involucrata, as well as late suc- cessional species such as Geranium richardsonii, Oreochrysum parryi and Thalictrum fendleri. Species growing in salvage-logged areas were primarily early successional disturbance specialists such as Chlorocrepis gracilis, Spegrularia rubra, Chamerion danielsii and shade- intolerant species such as Arnica cordifolia and Carex rossi. Community composition of each treatment area was distinct and related to a gradient in organic soil depth, which reflected the severity of understory disturbance. Nonnative species cover was less than 1% in all treatment areas, though 73% of all plots contained at least one non- native species. Nonnative cover was greater in blowdown areas than in control areas where total vegetation cover was also greater. Proportional cover of nonnative species was greater in salvage-logged areas than in other areas. Composition and diversity in blowdown areas relative to control areas stabilized in the five years following the blowdown, but vegetation cover continued to increase. Salvage logged areas exhibited a shift towards graminoid dominance, which could pre- vent or delay future conifer seedling estab- lishment. The third part of this study evaluated the effects of the wind and salvage-logging disturbance on biotic control of nutrient cycling. Inorganic nitrogen availability in the top ten cm of soil, rates of nitrogen cycling in the soil (net nitrification, net and gross nitrogen mineralization) and decom- position of leaf material did not differ between blowdown and control areas of intact forest. This suggests that tight biotic control is maintained over these ecosystem processes despite massive structural dis- ruption of the overstory in blowdown areas. In contrast, salvage-logging resulted in erosion of soil organic matter and soil compaction, which increased the carbon to nitrogen ratio of the top ten cm of soil, which is an inverse measure of soil quali- ty. Consequently, rates of nitrogen cycling (net and gross rates of nitrogen mineraliza- tion and potential nitrification rates) were significantly lower in salvage-logged areas than in blowdown areas. Leaf decomposi- tion rates in salvage-logged areas were ele- vated as a result of greater inorganic nitro- gen availability and carbon limitation from the lack of fresh leaf material in sparsely- vegetated salvage-logged areas. These results support the hypothesis that salvage- logging following wind disturbance con- verts a biologically intact system into a highly modified system, where reduced vegetation growth and abiotic factors such as soil erosion, compaction, and elevated surface temperatures are important factors driving ecosystem-level processes. Overall results of this study showed that despite massive structural disruption of the overstory, tight biotic control was main- tained over ecosystem processes in the blowdown. Recovery mechanisms includ- ed accelerated growth of understory seedlings and expansion of understory vegetation cover. Downed wood moderat- ed light and temperature conditions in a manner that favored vegetation growth. In contrast, mechanized salvage-logging resulted in elevated soil temperatures, soil Page 4 Aquilegia Vol. 30 No. 3 compaction and erosion, and reduced rates of nitrogen cycling in soil. Seedling density and understory vegetation cover were also reduced; new seedling establishment was minimal. Conditions in salvage-logged areas were similar to south-facing clearcuts where failures in natural regeneration are common, suggesting that if new seedling establishment remains low, reestablishment of forest cover in salvage-logged areas will be delayed. Thus, salvage-log- ging following windthrow disrupts recovery mechanisms, con- verting a biologically intact ecosystem into a modified state, where a shift in ecosystem regime is possible. Following the 2002 fires in the study area, I expanded the study to evaluate the effects of prior blowdown and salvage-logging dis- turbances on post-fire regeneration dynamics. In the first year fol- lowing a wildfire in the study area, vegetation growth and seedling establishment were very low. Newly established tree seedlings were found in previously undisturbed burned areas, but not in burned blowdown or burned salvage-logged areas, possibly reflecting the lack of seed trees in these areas. Wildfire resulted in increased inorganic nitrogen availability in the top ten cm of soil, and decreased soil carbon and nitrogen concentrations, but result- ed in no difference in net nitrogen mineralization rates relative to unburned areas. There were few differences among burned areas as a result of pre-fire disturbance history. Only soil carbon con- centrations were significantly lower in burned blowdown areas than in other burned areas, possibly as a result of greater fire intensity in burned blowdown areas. Differences in vegetation cover, seedling density and soil properties between unbumed blowdown, unbumed salvage-logged and control areas of intact forest were consistent with results of previous research. This study suggests that initially, the effects of a severe fire tend to "erase" the effects of previous disturbances on soil properties and nitrogen cycling. However, with time, the effects of disturbances that occurred prior to the wildfire may become more pronounced. Review of New Plant Taxonomy Textbooks Neil Snow, Ph.D. University of Northern Colorado Our knowledge of plant relationships has changed considerably over the past two decades. This article reviews two relatively new textbooks on plant taxonomy that reflect that knowledge. Since both are organized around the Angiosperm Phytogeny Group II (APG II) classification of Orders and Families, it is a safe bet that the APG II classification will be followed for some time. The first is Systematic Botany of Flowering Plants: A New Phylogenetic Approach to Angiosperms of the Temperate and Tropical Regions by R. E. Sprichiger, V. Savolainen, M. Figeat and D. Jeanmonod (2004; Science Publishers, Inc., Enfield (NH), USA and Plymouth, UD. ISBN (hardback) 1-57808-3 15-X. See http://www.scipub.net. List Price: $85.00). This book has 414 pages in 6 chapters (History of Botanical Classification; Species and Speciation; Floras and Vegetation; From Algae to Angiosperms; Evolution and Classification of Plants with Seeds; and Selected Orders and Families). The largest part of the book is the "Descriptive Plates of Families," where numerous families are given a 2-page spread. On the left is a description of the family, including approximate number of genera, the approximate num- ber of species and its geographical range. Next is the description of the family and its placement in previous classification systems and useful plants and floral diagrams. The right page shows black and white line drawings of branches, flowers and fruits, and black and white photographs showing details of smaller structures such as stamens. Next are four Annexures (appendices), the first being a glossary and the second being a "Key to Identification of Tropical Families by Observation of Vegetative Characters." You may wonder why the authors would include 12 pages on tropical family identification with numerous line drawings. Three reasons suggest themselves to me. First, the greatest diversity of flower- ing plants occurs in the tropicals. Two, much of that plant biodi- versity is being lost at an alarming rate and time is running out to document it. Third, botanists in the tropics typically learn to iden- tify families first by their vegetative characters. The third annex- ure is the Taxonomic Index and the fourth is the List of Species Illustrated with Colour Photographs on the CD-ROM, which con- tains 300 images of species, with 3-4 photos for most families ranging from excellent to marginal quality. The last page, the "General Outline of the Taxonomic Organization of the Book, with a List of the Families Described", depicts a phlyogeny of the main lineages of angiosperms with the families treated listed at the tips of each branch. The text is compact and only slightly larg- er than a typical "Peterson" field guide. It differs from many plant taxonomy textbooks by its absence of a North American focus. I would most likely adopt this book when teaching plant taxonomy in a tropical field course. The other new text is Plant Systematics by Michael G. Simpson (2006; Elsevier Academic Press. ISBM (hardback) 0-12-644460- 9. List price: $69.95). The book is 590 pages with dimensions of a college textbook. The text is divided into four units. Unit 1 "Systematics" (2 chapters) provides an overview of plant system- atics and phylogenetic systematics. The latter is lengthy, but I highly recommend it to those who want a better understanding of that topic. Unit 2 "Evolution and Diversity of Plants" (6 chapters) covers the classification and descriptions of all the major lineages of plants and many of their families. This section is lavishly illus- trated with good to excellent color photos. In fact, it is hard to imagine a better-illustrated volume. Unit 3 "Systematic Evidence and Descriptive Terminology" (6 chapters) covers aspects of plant morphology, anatomy, embryology, palynology, reproductive biology and molecular systematics. These topics are covered with care and the rich color layouts are evocative of the excellent stan- dard set by the many editions of Biology of Plants by Raven, Evert and Eichhorn. Unit 4 "Resources in Plant Systematics" has chap- ters on plant identification, nomenclature, collecting and docu- mentation, herbaria and data information systems, and three appendices (plant descriptions, botanical illustrations, and plant systematics journals). A glossary of terms and index completes the text. In my view Simpson has established the new standard by which plant taxonomy textbooks will be modeled, and I predict this book will be widely adopted at the tertiary level. In summary, both texts follow the APG II classification, have their individual strengths, and likely will be used for different roles. Vol. 30 No. 3 Aquilegia Society Announcements Page 5 Book Review The Enchanted Mesa; an Introduction to Its Natural History by Url Lanham Defined by the author as the tableland and canyons between Bluebell Canyon and South Boulder Creek, the Enchanted Mesa is part of Boulder's open space along the Flatirons. Illustrated by the author's daughter, Margy Lanham, The Enchanted Mesa was written by Url Lanham in 1974. This charming book is intended for the casual reader and contains no index or bibliography. The main portion of the book deals with the vegetation of the area, although the geology and wildlife are also discussed. Entries for each plant are brief, but Lanham's observations provide enjoyable reading. For example, "Evening primrose {Oenothera strigosa). A tall, bushy plant, two or three feet high, with the yellow flow- ers rather small for an Oenothera. Pollinated by a strange, small bee that flies in early dawn, furnished with special pollen brush- es to handle the large pollen grains that come in strings, and with large ocelli (the "simple" eyes) for use in the dim light." (p.79) Each plant description is accompanied by a line drawing. Url Lanham, who passed away in 1999, was Professor Emeritus at the University of Colorado in Boulder. He was the author of many scholarly papers as well as numerous books including The Bone Hunters and The Sapphire Plant. A number of copies of The Enchanted Mesa, an out-of-print hard cover book, have been obtained by the Colorado Native Plant Society and are available for purchase from the Sales Committee. - Jan Loechell Turner Society Awards The Board of Directors of the Colorado Native Plant Society desires to honor contributions to Colorado botany and the Society with the following types of awards.

Pediocactus simpsonii is a common outer foothills plant, but this observation might mark its upper limit and pose an interesting problem. In 1994 or 1995 we found a veritable carpet of these on top of the Bald Mountain that lies west of Sugarloaf Mountain between the two arms of the Switzerland Trail. The new Boulder County trail map gives the altitude at 9,147 feet. This spring we thought it would be fun to visit the cactus display again, but on the summit we found only one live ball cactus and one dead or nearly invisible one. There wasn't a trace of the dense growth we had found before. On the south-facing meadow (8,100 feet) we have found the ball cactus flowering regularly for 14 years. Has anyone an explanation for the sudden crash of a stand like that on Bald Mountain? Does anyone know about the normal longevity of these plants? Is this stand an altitude record? There is so much we don't know about the life history of some of our most common plants. Contact Dr. William A. Weber, at weberw@buffmail.
