In the summer of 1997, the Kaibab National Forest released the Draft Environmental Impact Statement for Tusayan Growth. This report analyzed various scenarios involving the transfer of National Forest land at the boundary of the Grand Canyon National Park to a private developer, in exchange for private inholdings scattered throughout the Kaibab National Forest in northern Arizona. The resulting private development was to be called Canyon Forest Village, and would include hotels, visitor facilities, private housing, community facilities and a transportation center for tourists accessing the Grand Canyon. The proposed build out of Canyon Forest Village (CFV) was to take place from 1999 to 2010. Consequently, the Forest Service analysis used that time frame as the basis for calculating the economic impacts CFV would be expected to have on local economies in the northern Arizona region. The Draft Environmental Impact Statement (EIS) concluded that overall growth in demand for lodging in northern Arizona would be robust over those years, and that CFV would have no net negative impacts. The results of the Draft EIS were sharply contested during the public comment phase, and, in the summer of 1998, a Supplement to the Draft Environmental Impact Statement for Tusayan Growth was issued. This document used a different modeling procedure and changed its primary focus to two, smaller, CFV proposals, involving only 900 and 1,270 hotel rooms. The Supplement did conclude that there would be some negative impacts to the communities surrounding Grand Canyon. The results of the Supplemental Draft EIS were also contested during the public comment phase following its release, although a year later, in the summer of 1999, the Forest Service issued a Final EIS and adopted the CFV proposal for 1,270 rooms. One peculiarity of the Forest Service reports, throughout this process, was the failure to identify an explicit discount rate of interest in order to identify costs and benefits in terms of their present value. While EIS documentation has been required for many years, the obvious focus is on purely environmental concerns and the analyses tend to be based on scientific findings. The inclusion of a socioeconomic analysis necessitates a careful accounting of benefits and costs. While this EIS is not the first to include an explicit accounting of economic benefits and costs, it may serve as a harbinger of more reporting of this type. Unless those with an appreciation of the discounting process, especially economists and accountants, are included in these analyses, present values may be employed only on an erratic basis, making the results of such reports difficult, if not impossible, to adequately interpret. This article applies basic and commonly accepted time value of money principles to an EIS report. Although an economic analysis was provided as part of the report, the time value of money was ignored. In order to present a viable economic impact, these basic financial tenants must be employed. The authors used basic time value of money principles with reasonable discount rates. The result is that impacts could be as much as six times greater than the values given by the Forest Service, representing upwards of one hundred and fifty million dollars.

It is generally presumed that intensive survey yields reliable representations of regional archaeological variability. We evaluate this assumption with an analysis of the results of two intensive surveys of the same terrain in the Upper Basin, a heavily forested upland ecosystem located south of Grand Canyon National Park in Kaibab National Forest, northern Arizona. By comparing differences between the results of site-based surveys with those of mapping-unit-based surveys, we demonstrate that units of observation have a profound effect on how archaeological landscapes and their variability are characterized and interpreted. In addition, results of four analyses of survey data show that the archaeological resource inventories created by the application of these two different units of observation cannot be reconciled. We suggest that because some units of observation may be more appropriate for certain problems and for different kinds of surface and near-surface archaeological records, additional studies of the effects of units of observation on characterizing the archaeological content of the same terrain should become a research priority in survey archaeology. Without such studies, the identification of archaeologically sensitive areas, particularly those that necessitate active management and vigilant protection on public lands, will be underdetermined, thereby placing those heritage properties at risk.

In the southwestern United States, populations of quaking aspen (Populus tremuloides Michx.) are experiencing widespread mortality. Although environmental factors contributing to mortality have been well characterized, less is known about how genotype and particularly ploidy level affect susceptibility. We used five microsatellite markers to infer the ploidy level of 212 aspen stems in Kaibab National Forest, Arizona. Many multilocus genotypes showed three alleles at one or more loci, suggestive of frequent triploidy among our samples. Sites populated with putative triploids had higher mortality. In addition, heterozygosity was positively associated with mortality and crown dieback. Our results suggest that triploidy is a predisposing factor for aspen mortality in Kaibab National Forest.

National Historic Preservation Act

Many land managing agencies have policies that forbid the collection of artifacts during archaeological survey and, even under controlled situations, collection is determined to be an “Adverse Effect” under Section 106 compliance interpretations of the National Historic Preservation Act. The main rationale is that removal destroys the contextual information of the artifact in relation to the rest of the site. This paper argues that such “non-collecting policies” are short-sighted and do not “protect” artifacts from unauthorized removal. In these days of technology, when sub-meter GPS instruments and other tools are available to pinpoint the location of artifacts, we submit that not collecting artifacts with important information potential is deleterious to interpreting the archaeological record. This point will be made by a case study from the Coconino National Forest in northern Arizona that illustrates the excuse “if I don’t pick it up, someone else will,” is a correct assumption. Surface collections, properly documented, provide useful information that justifies their collection and curation for present-day and future research.

Abstract The costs of prescribed burning in ponderosa pine residual fuels vary widely among national forest districts in northern Arizona; costs ranged from less than $3. to over $30. per acre. Most of the variability was due to the time required for burning. Five high-cost districts averaged 114.4 person-hours to complete a medium-sized burning project whereas seven low-cost districts required an average of only 29.1 person-hours. Sensitivity testing showed that burning block size, burning crew size, fireline preparation time, and travel time can also have significant impacts on costs. Costs generally declined with increases in block size and crew size and with reductions in preparation and travel time. West. J. Appl. For. 3(4):115-119, October 1988.
