A Finlândia desempenha um importante papel entre os países produtores e exportadores de madeira e seus derivados. Em consequência disto, o país também dá grande importância à pesquisa florestal. Este trabalho objetiva, em decorrência do convênio de pesquisa recentemente assinado entre a Universidade Federal do Paraná e o Instituto Finlandês de Pesquisas Florestais, fornecer ao leitor brasileiro informações de caráter geral e, especialmente, florestal sobre este país.

The objective of this research was to develop prediction equations in order to estimate the moisture content of dead forest fuel in a loblolly pine stand, through the use of standard sticks. The research material was collected between May and August from a 18 years old stand, and separated in four classes: i) neddles; ii) woody material up to 0.7 cm diameter; iii) woody material from 0.7 to 2.5 cm diameter; iv) woody material from 2.5 to 7.6 cm diameter. Three different sizes of sticks were used: one for estimatíng the moisture of needles and woody material up to 0.7 cm and the others for each remainning fuel size class. The sticks were made from brazilian pine wood. The prediction equations based on the weight of the standard sticks did not present good predictions for the moisture content of the forest fuels, under the studied conditions.

This paper deals with a preliminary analysis of the Metric Camera photography of a forest area on Mato Grosso do Sul State, Brasil. It was not possible to distinguish the diffe» rent vegetation types based only in the visual interpretation of the Stereoscopic model. The Metric Camera photography is shown to have a great potential as a data source for natural resource management. It has stereo capacity and good resolution and because of its small scale, 11800000, permits an excellent sinoptic view.

This paper deals with the acquisition of 35 mm ground stereo photographs using one camera. The usual trees in the arborization of Curitiba were photographed in two different seasons of the year. Technical and practical aspects related with the acquisition and stereo observation are discussed. The ground stereopairs has been introduced in the practical cias- ses of Forest Photo-Interpretation and DendroIogy.
