This study attempts to analyze the professional situation of those technicians who have graduated from Colegio Florestal, a technical high school in the state of Parana in the South of Brazil. The data was gathered through mailed questionaires filled out by 73% of these technicians. The first research objective was to establish the percentages of those who work as forest technicians and those who do not. Secondly it was verified as to whether any differences might be attributed to the professions of the respondents fathers.
As far as the graduate students who work in the forestry sector are concerned a number of variables have been analyzed. They include the geographic distribuition, the types of enterprises where they work and the activities they perform. The wage and salary structure and the position the ocupay in the organization structure of the enterprise or instution was also analyzed. Finally, the level of job satisfation of the forest technicians was studied. Certain recomendations concerning forest education and policy are presented at the end of the paper.

This study intends to evaluate the damages caused to a Pinus taeda stand by forest fires ocurred on September 9, 10 an 11, 1981. The stand was located in Palmeira county, State of Paraná, Brazil, and the ages of the trees ranged from 8 to 10 years. Four levels of fire intensity were visually defined: I) Surface burning, without lethal crown scorch; II) Surface burning, with partial lethal crown scorch; Ill) Partial consumption of the crowns by the flames, and IV) Total consumption of the crowns by the flames. The estimated fire behavior parameters were flame height, Byram's fire intensity, and lethal scorch height. The average fire intensities were 44.3 kcal/ m-s for level I; 293.0 kcal/m-s for level II; 1,680.6 kcal/m-s for level lll; and 12,345.6 kcal/m-s for level IV. Average lethal scorch height were 1.4 and 9.7 m for Ievels l and II respectively, surpassing the trees height for levels lll and lV. In the areas where fire intensity reached levels lII and IV all the trees were killed by the fire. On level ll damage was partial and the trees recovered well. On level I fire intensity was too low to cause any kind of damage to the trees.

The urban forestry minimize the effects of the microclimatic instability and also the atmosoheric, hidric, and visual pollution wich affect the urban life quality. Resulting thus, the necessity of better planning and maintenance of urban threes. In this study, an inventory of street trees was carried out within an error limit of 15% and the 95% probability level, with the main purpouse of,analise the existent relation between the ne- cessity of trees care and the characteristics of arborization planning. The diversity of species and the physical and sanitary conditions of street trees were studied as influent factors in the urban fores- try management. To conclude, it is possible to minimize the maintenance costs and improve the urban plantings through: il) adequate seletion of species; (2) using the adequate form and size to the disponible space; (3) improvement of the plant quality and; (4) improvement of the today adopted tree care.

This research was carried out in the county of Rio Branco do Sul, State of Paraná, with the objective of identifying the most efficient forest fire danger index for the region. Meteorological data were collected from the ”Fazenda Brejal“ station, located at Trombini Forestry Company. Data of forest fire occurences were collected in Rio Branco do Sul and neighboring counties of Almirante Tamandaré and Colombo, from May 1979 to December 1982. The compared forest fire danger indexes were Angstron, Nesterov, Telicyn, and Monte Alegre formulas. During the observa- tion period 31 forest fires were recorded, 11 in Rio Branco do Sul, 3 in Almirante Tamandaré, and 17 in Colombo. Considering only the data from Rio Branco do Sul, the Monte Alegre formu- la was the most efficient, with a much better performance than the other indexes. Including the data from the other counties, MA formula was still the first choice, but its performance was not much better than the Teiicyn index. The Angstron formula was the most inefficient index, indicating forest fire danger only in 4 out of 31 days of fire occurence.
