Switzer Provincial Park to determine use and user characteristics and estimate the nonmarket economic value of camping. Data were collected from camping permits during the 1995 camping season. A zonal travel cost model employing count data econometrics was used to estimate nonmarket economic values associated with camping. Results showed that over 24 000 people camped in the model forest, and camping parties spent more than 16 000 nights in the model forest. Campgrounds were used primarily by Albertans. Most campers were from outside the model forest area. The campgrounds were used mostly as one-night stops or weekend and long weekend destinations. Differences were observed between campers at the provincial park and at the provincial recreation areas, suggesting the two types of camping opportunities are attracting different types of campers. The travel cost model estimated consumer surplus at about $58 per trip. The estimated benefit flow to Albertans derived from managed campgrounds in the Foothills Model Forest is $436 600 (in 1995 dollars) per annum.Tue, 22 Aug 2000http://cfs.nrcan.gc.ca/publications?lang=en_CA&page=4&id=11947http://cfs.nrcan.gc.ca/publications?lang=en_CA&page=4&id=11907Scientific, technical, and interpretive publications written by staff of the Northern Forestry Centre during 1994–96 are listed alphabetically by author.

The bibliography includes references spanning the years 1817 to 1996, inclusive. References are arranged alphabetically and consecutively numbered. Indexes for authors, subjects, hosts, and geographical distribution are included.The purpose of this bibliography is to provide easy access to published information on this group of forest insects, much of which is not readily accessible through on-line data bases.Tue, 22 Aug 2000http://cfs.nrcan.gc.ca/publications?lang=en_CA&page=4&id=11891http://cfs.nrcan.gc.ca/publications?lang=en_CA&page=4&id=11639The Forest-Fish Conference was held on May 1-4, 1996, in Calgary Alberta. The conference provided a forum for the exchange of information concerning the relationships between forest land-use activities and aquatic resources among an international assemblage of technical experts. Presentations were made on the relationships between forest harvesting activities and stream flows; road construction and sedimentation; degraded riparian area recovery and improved livestock management; stream ecosystem protection; and timber harvest and riparian buffer requirements. management solutions that improve watershed protection and minimize the impacts of forest land-use activities on aquatic environments were discussed. Fifty papers from this meeting are presented in this volume.

Although the essential details of its life cycle are well known, the development of the insect with respect to its host plant is poorly understood. Large aspen tortrix and trembling aspen bud and shoot development are described from observations at two sites in 1994. Degree-day models based on a common threshold temperature of 5 C were developed for both insect and bud and shoot development of its host. Parameter estimates for models of aspen development suggest that there is considerable variation in budbreak between sites, whereas C. conflictana exhibited less variation of this kind. Parameter estimates for C. conflictana development models were somewhat at odds with plots of the raw data for the onset of feeding. Clonal control of phenological development of aspen and microsite differences in temperature regimes are among the phenomena that must be considered if the models to predict phenological events accurately in the field are to be improved.

These results are based on assessments made on 17 permanent biomonitoring plots and assessments of major forest disturbances. Brief descriptions are given of major forest disturbances in the region, including forest tent caterpillar (Malacosoma disstria Hbn.), which defoliated 411 855 ha of trembling aspen forests; lodgepole pine dwarf mistletoe (Arceuthobium americanum Nutt. ex Engelm.), which causes severe disease on 428 541 ha of pine forests; spruce budworm (Choristoneura fumiferana [Clem.]), which defoliated 760 131 ha of white spruce–balsam fir forests; and forest fires, which destroyed 492 027 ha. Current climatic data from across the region are compared to 30-year normals for a number of parameters. Details of the assessments completed on the 17 permanent biomonitoring plots in the region are also given. Generally, tree condition of jack pine, lodgepole pine, white spruce, and trembling aspen on the biomonitoring plots was good, with most trees having less than 25% crown damage. Annual mortality rates were within the range of 0.4–3.3%. The state of regeneration on the biomonitoring plots is also discussed. Descriptions of the current status of quarantine pests in Canada of concern to the forestry sector are given. Tue, 22 Aug 2000http://cfs.nrcan.gc.ca/publications?lang=en_CA&page=4&id=11633http://cfs.nrcan.gc.ca/publications?lang=en_CA&page=4&id=11586Subsistence and non-industrial forest uses are important in many northern communities. In some communities, these forest uses may provide more economic value than commercial forest activities. This study uses the replacement value method to estimate the value of some subsistence and non-industrial forest activities to two communities in the lower Liard valley, Fort Liard, and Nahanni Butte. Results show that these forest uses provide between $950 000 and $1 700 000 of income and in-kind income to valley residents. In addition, forest resources are widely shared throughout these communities. Over half the harvests of meat, fuel, berries, and other subsistence goods are given to persons outside the harvesters household. Comparison of contemporary harvest data to the historical data that exists suggests that subsistence and non-industrial forest activities are equal to or greater than historical harvests over the past thirty years. Tue, 22 Aug 2000http://cfs.nrcan.gc.ca/publications?lang=en_CA&page=4&id=11586http://cfs.nrcan.gc.ca/publications?lang=en_CA&page=4&id=11579One-hundred-year-old mixed white spruce–aspen stands were partially cut in 1953, 1954, and 1955 and scarified leaving treatments that retained 14–100% of total stand basal area. Composition of the stands based on measurements of 88 (0.081-ha) permanent sample plots before and after cutting, and in 1992, is described. Mortality assessments in 1960 showed that all levels of partial cutting resulted in acceptable residual stand losses during the early establishment period. Residual white spruce mortality, 5–7 years after logging and scarification treatments, ranged from 6–7% on non-cut controls to 23% on heaviest cut treatments. On treatments where hardwoods were not cut, hardwood mortality ranged from 2 to 3% over the same period. Development and decline of the partially cut stands are described in terms of residual trees, snags, and windfalls in 1992. Development of softwood regeneration and hardwood reproduction is also described. Basal area of 37-year-old hardwood reproduction increased with cutting intensity and ranged from 1.1 to 16.1 m2/ha, exceeding original hardwood basal area on the two heaviest cut treatments. Numbers of suckers increased from 131–420 stems/ha on treatments where hardwoods were not cut to 170–1368 stems/ha on treatments where all hardwoods were cut. White spruce regeneration was 10 times more abundant on scarified seedbeds and better beneath residual hardwoods than under hardwood reproduction that developed on hardwood-cut treatments. Both hardwood reproduction and natural white spruce regeneration increased sharply as residual white spruce was reduced to 4.4 m2/ha. Options for renewing mature mixedwood stands are discussed.Tue, 22 Aug 2000http://cfs.nrcan.gc.ca/publications?lang=en_CA&page=4&id=11579http://cfs.nrcan.gc.ca/publications?lang=en_CA&page=4&id=12149Methods for sampling, collecting, and rearing parasitoids of eggs, larvae, and pupae of the forest tent caterpillar, Malacosoma disstria Hübner, in the prairie provinces are discussed. Illustrated keys are provided for the identification of 42 Diptera and Hymenoptera species, which are parasitoids, hyperparasitoids, and scavangers associated with the forest tent caterpillar. Twenty-nine of these species are known to associate with forest tent caterpillar in this region, and another 15 occur in adjacent regions and are likely to occur there as well. A brief discussion is given of the biology, abundance, and probable role of each species identified. A glossary is included.

This study examines campers at forest recreation areas in the Rocky-Clearwater Forest of Alberta to determine total campground use and user characteristics. Camping fee envelopes were modified to provide a relatively inexpensive means of data collection. Data were collected from the 33 campgrounds that collected fees during the 1994 camping season. Data were then linked with Statistics Canada census data to obtain estimates of socioeconomic characteristics. Geographic information systems technology was used to determine and map market areas. Results showed that the campgrounds are used primarily by Albertans who live within a 1- to 2-hour drive of the forest. July received more visits than the other months. The campgrounds are used mostly as one-night stopovers or as weekend camping destinations. Cluster analysis identified two subgroups of campers, suggesting that visitors are not a homogeneous group and may have differing recreational needs and opinions of forest management. The study employed existing systems for data collection and provided accurate use data and information on user characteristics. Existing systems and data bases should be examined more critically for user information that will assist management efforts in understanding social values associated with the forest.

Most items in this collection were produced prior to 1993 and pertain to the United States, Australia, and Canada. They provide information on a diverse spectrum of topics related to fire management in the wildland-urban interface ranging from building materials and hazard reduction techniques to disaster management, politics, and sociological issues. The citations have been indexed by subject, using over 50 headings, and according to three general categories: general and technical materials, newspaper articles, and public education materials.Tue, 22 Aug 2000http://cfs.nrcan.gc.ca/publications?lang=en_CA&page=4&id=11794http://cfs.nrcan.gc.ca/publications?lang=en_CA&page=4&id=11638Forest insect and disease conditions in Alberta, Saskatchewan, Manitoba, and the Northwest Territories are summarized for 1995. Ground and aerial surveys included mapping pest infestations, trapping pests using pheromone-baited traps, conducting field pest collections and identifications, measuring damage intensity, and updating of pest distributions and their hosts throughout the study area. Infestations of and defoliation by spruce budworm, forest tent caterpillar, large aspen tortrix, aspen leafroller, mountain pine beetle, spruce beetle, Douglas-fir beetle, lodgepole pine dwarf mistletoe, satin moth, gypsy moth, and Dutch elm disease are discussed and compared to 1994 levels, as are other pests specifically affecting forest nurseries. An update of surveys for acid rain symptoms in permanently established Acid Rain National Early Warning System plots is also reported. Other noteworthy insects, diseases, and tree damage agents are discussed in tabular form. Forecasts of spruce budworm, jack pine budworm, and forest tent caterpillar populations are reported for 1996.Tue, 22 Aug 2000http://cfs.nrcan.gc.ca/publications?lang=en_CA&page=4&id=11638http://cfs.nrcan.gc.ca/publications?lang=en_CA&page=4&id=11601In 1951 and 1952, 121 permanent sample plots were established at 16 locations in mixed stands of white spruce (Picea glauca [Moench] Voss) and trembling aspen (Populus tremuloides Michx.), which had undergone partial cutting that had removed the largest white spruce. These stands were re-examined in 1962 and 1993 to assess growth rates and productivity of mixed stands after partial cutting and determine whether a similar harvesting technique would ensure future harvests of white spruce. This study, based on plot data and increment core measurements of spruce sample trees, showed generally excellent diameter and volume growth response by the residual spruce. Wind damage was the main cause of mortality and averaged about 1.8% per year in terms of residual spruce volume. A multiple regression model with four independent variables fitted to the data provided reasonable predictions of spruce merchantable volume yield for similar stands. A model with two independent variables (residual spruce volume and years since logging) explained 74.1% of the variation in postlogging merchantable spruce volume yield. Highly variable mortality among deciduous trees prevented the development of practical volume prediction models for that component.Tue, 22 Aug 2000http://cfs.nrcan.gc.ca/publications?lang=en_CA&page=4&id=11601http://cfs.nrcan.gc.ca/publications?lang=en_CA&page=4&id=11587Controversy over the expansion of commercial forestry in northwest Saskatchewan has led to changes in forest management in that area. The decision-making framework in the NorSask Forest Management Licence Agreement (FMLA) area is evolving toward co-management. Local community members enjoy a growing role in forest management as local industry attempts to build an institutional structure for forest decision making that more effectively incorporates local views, values, and concerns. This paper describes the history of controversy over forest development and reviews relevant theory on social movements and collective action. A framework for evaluating the level or degree of co-management in northwest Saskatchewan is provided. This evaluation framework provides a snapshot of co-management at a given point in time. While co-management is not fully developed in the region, the trend toward greater local stakeholder participation in forest decision making appears positive.Tue, 22 Aug 2000http://cfs.nrcan.gc.ca/publications?lang=en_CA&page=4&id=11587http://cfs.nrcan.gc.ca/publications?lang=en_CA&page=4&id=22067Wed, 25 Jun 2003http://cfs.nrcan.gc.ca/publications?lang=en_CA&page=4&id=22067http://cfs.nrcan.gc.ca/publications?lang=en_CA&page=4&id=21860Mon, 09 Jun 2003http://cfs.nrcan.gc.ca/publications?lang=en_CA&page=4&id=21860http://cfs.nrcan.gc.ca/publications?lang=en_CA&page=4&id=21856Mon, 09 Jun 2003http://cfs.nrcan.gc.ca/publications?lang=en_CA&page=4&id=21856http://cfs.nrcan.gc.ca/publications?lang=en_CA&page=4&id=19037Mon, 10 Dec 2001http://cfs.nrcan.gc.ca/publications?lang=en_CA&page=4&id=19037http://cfs.nrcan.gc.ca/publications?lang=en_CA&page=4&id=19013Fri, 07 Dec 2001http://cfs.nrcan.gc.ca/publications?lang=en_CA&page=4&id=19013http://cfs.nrcan.gc.ca/publications?lang=en_CA&page=4&id=18989Thu, 06 Dec 2001http://cfs.nrcan.gc.ca/publications?lang=en_CA&page=4&id=18989http://cfs.nrcan.gc.ca/publications?lang=en_CA&page=4&id=12135The jack pine budworm symposium was held on January 24-26, 1995, in Winnipeg, Manitoba. Twenty-one papers were presented on the biology and management of jack pine budworm. Presentations were made on the geographical and historical extent of jack pine budworm outbreaks, the regional perspectives on population management, population biology, as well as the hazard and vulnerability of stands to damage by the insect. Workshops were held on population measurements and management options.

In addition, the prioritization of research needs based on their value to the user agencies, and the process of fire research at the Northern Forestry Centre, Edmonton, Alberta, were also discussed by respondents. The questionnaire was completed by 43 professionals, primarily from fire management agencies, the forest industry, academia, and selected resource management agencies. Seventy research needs were ranked for the region and for the provinces and territory according to their present importance (1–2 years) and future importance (3–5 years). In addition, 36 activities were identified by users as potential research activities.
