The research was focused on visitors to the Blaník Protected Landscape Area (hereafter referred to as PLA), a well-known recreational area where data on visitors, important for PLA management, are missing. Therefore, the aim of the paper is find out: what kind of visitors comes to the study area; the type of forest trails and tourist facilities the visitors prefer. A questionnaire survey of forest visitors was used. Results show that the visitors mostly prefer maintained trails. According to forest visitors' opinion, the most convenient facility to place near the forest tourist trail is the nature trail panels. Furthermore, based on the acquired data, it was possible to create a visitor's profile which is important for respective research and other case studies in similar areas, and for managers of protected landscape areas to comply with both the visitors' needs and the needs of the protected area.

The examination lied in comparing the foliar concentrations of Ca, Mg, K, N, P, Fe, Mn, Zn and Cu with the critical values referring to conifers and the elemental percentages with regard to N of the forest with the corresponding percentages of a healthy Bulgarian fir (Abies borisii regis) stand, the closest relative of the Greek fir. It was found that the needles of the Greek fir had significantly lower concentrations from the N and P critical values. Significant differences were found for the Ca/N, Mg/N, P/N, Fe/N and Mn/N percentages. Significant correlations for the Greek fir were found between needle weight and foliar N as well as between needle weight and the percentages Ca/N and Fe/N. It is highly probable that N and P in the Greek fir are in short supply.

The logging operation was performed by chainsaw and cable skidder. Prelogging, after felling and skidding operations residual tree injuries (species, DBH and damage) were inventoried by systematic plot sampling. Two types of tree damage were observed: destroyed and injured. In this study felling operations mainly injured trees whereas skidding was the main cause of destruction. The percentage of destroyed and injured residual trees by felling operations was 1.4% and 3.4%, whereas the percentage of destroyed and injured residual trees by skid­ding operations was 5.2% and 11.1%. About 87% of destroyed trees were found in the DBH class smaller than 22.5 cm. Maple and Alder were the most damaged trees among the other trees species. Damage to the lower bole and wood damaged intensity were the most common type of injury. To reduce the stand damage, skid trails should be planned before felling and felling directions should be predetermined. In the selection cutting management, limiting logging damage to residual trees must therefore remain a major objective.

Two sites planted with Eucalyptus globulus were selected to study these harvesting systems. A time and motion study was applied to collect the data for both harvesting systems. The working cycles for each machine were recorded as well as the variables af­fecting the working productivity. Using the multiple regression method the appropriate models were developed. The results showed that the productivity of feller-buncher and processor was significantly affected by tree size. Productivity of skidders was dependent on extraction distance and load weight. Productivity for road side processing was higher than for road side chipping, which resulted in a lower unit cost. The unit cost (from stand to the mill) for road side processing and road side chipping averaged 22.68 AUD.t-1 and 21.07 AUD.t-1, respectively.

This paper presents the research results of the performance of loading with Volvo 4500 BM and timber trucking using two types of common trucks in the Nav watershed in Iran. Both trucks can carry logs shorter than 7.8 m in length. The study used a time study based on empirical data for loads collected from one procurement district in the Nav watershed. The models included the following explanatory factors: driving distance, number of logs, and load volume. The time consumption and productivity of loading and timber trucking depends on several variables such as volume and number of logs per cycle. To evaluate the current transportation system in the Nav watershed, the empirical time study was conducted. Since transportation includes several phases and since many factors affect the work performance, significant variation in the total transportation time was observed. This makes planning and cost accounting more difficult. The models developed in the study are a promising way to support route planning and optimization, and cost and profitability calculation for trucking en­trepreneurs and the forest industry. The average productivity of log transportation was 2.84 and 3.4 m3.effective h-1 for the dump truck and chassis truck, respectively. The average hauling unit cost was 18 and 15 USD.m-3 in the dump truck and chassis truck, respectively.
