In Canada, Lemmon's Holly Fern, Polystichum lemmonii, is restricted to the Baldy Mountain area on the eastern side of the Okanagan River valley in south-central British Columbia. This population represents the northern limits of the species which ranges south through northern Idaho, Washington and Oregon to northern California. In British Columbia, P. lemmonii is associated with ultramafic rocky ridges within a montane forest at an elevation of 1900 m. The population in the Baldy Mountain area is relatively small, unprotected and potentially imperilled by mining exploration, forest road construction or wildfires.

Forest Road Construction

Abstract A computer program has been developed to aid forest engineers in the cost estimation of forest road construction activities. This new tool, called ACCEL, uses Visual Basic for Applications within Microsoft Excel to compute the costs of construction components using interactive sheets, automated tasks, and advanced computer routines. The user is guided through road construction components and prompted for cost data, earthwork quantities, survey information, and the conditions of the construction environment to estimate total construction cost. Road design elements and site characteristics are variables used to optimize earthwork allocation, improving on using the mass diagram method. The program also estimates clearing and grubbing areas, rock surfacing volumes, and culvert lengths. ACCEL was validated by comparing the results to those of RoadEng (by Softree), ensuring that formulas were input correctly and showing close agreement in results. This program was created in a recognizable format, i.e., Microsoft Excel, and builds on basic quantity and cost estimation techniques. ACCEL is intended to improve the decisionmaking process for experienced forestry practitioners in forest road construction regardless of region, company, or agency affiliation by accepting their inputs and performing the calculations for different route alternative or varying design specifications.

The basic condition of forest management development is the accessibility of the forest. A design of the forest road network in relation to all-society functions of forests has been made in the catchment of the Vilčok stream. The catchment is situated in Protected Landscape Area Beskydy. The method Quantification and quantitative evaluation of functions of forests as a basis for their evaluation (Vyskot et al. 2003) was used for the design. This method can be applied to road planning. It can serve as another component in the decision-making process of the planning of forest road construction.

Основной целью работы является оптимизация использования машин для земляных работ в строительстве лесных дорог по критерию минимума приведенных расходов, путем оптимального распределения комплектов машин по объектам строительства при условии возможности аренды какихлибо дополнительных машин. Создана экономикоматематическая модель расчета эффективной структуры парка машин с точки зрения системы производственной эксплуатации, которая складывается из эффектов всех специализированных комплектов машин и эффекта от передачи машин парка в аренду. Учет возможности передачи или получения техники в аренду позволяет улучшить техникоэкономические показатели эксплуатации парка машин. Результаты работы могут быть востребованы лесозаготовительными и дорожностроительными предприятиями в период проектирования производства земляных работ, обновления машинных парков, а также при выборе наилучшего варианта использования имеющегося парка, прогнозирования продолжительности и стоимости ведения механизированных работ. The main purpose of this work is to optimize the earthmoving machinery utilization in the forest road construction, by minimize the operating cost. That goal may achieve by the optimal distribution of the machine combination in the construction sites, with the ability of renting additional machines. Economical mathematical model has been developed for calculating the effective structure of the machine group to achieve the required productivity. The possibility of hire and rent machines allows the manager to improve the technical economic decision for the machines operation. By using the developed model it can gives good results to having better decisions for planning and designing the earth working operations in the road construction companies, renovation of the machine parks, as well as the choosing the best option for using the existing machine combination, predicting the duration and predicting the cost of the whole work.
