This special issue was proposed by the Organizing Committee of the commemorative event of the fifty years of the Graduate Program in Forestry Engineering at the Federal University of Paraná - 1972-2022. The issue contains 5 papers focusing on silviculture, management of native and planted forests,...

We assess the conditions under which forest-dependent groups in the Brazilian Amazon Rainforest may overcome inequalities in the legal access to forest resources. Through the development of contrasting case studies, we address attempts made by two community-based associations that represent those...

The tension between the large global demand for tropical timber, and ecological sustainability and local socioeconomic development in the fragile natural ecosystems of the Amazon region has challenged many generations. In this case study, carried out in an ecotone forest in the northern Brazilian...

Timber production in sustainable forest management must be carried out in periodic cycles, respecting the forest's resilience. However, logging is based on old-growth forests, and little is known about logging beyond the first cutting cycle. The study investigated the financial feasibility of the...

This study analyzed the diametric distributions before and after forest management in a rainforest area of the Amazon in the Amapá State, Brazil. It aimed to understand how the diametric distribution of the forest was recovered after 27 years of forest management between 1984 and 2011. For this...

Addressing urban forest management and governance challenges is fundamental for implementing urban forest policies. Most of the evidence on this topic comes from Global North cities, so little is known about how urban forest management and governance are experienced by urban forest actors in Global ...

There is a lack of understanding on the relationship between the authorized volume of wood harvest in Sustainable Forest Management Plans (SFMP) in the Amazon, the volumes listed in the official systems of volume control, the actual harvested volumes, and the consequences these parameters have for...

Can heavily logged Amazonian dense forests produce commercial timber for a second harvest under a 25-35-year cutting cycle? To address this question, we evaluated the forest capacity to recover the volume extracted 32 years after heavy logging (90 m³ ha^-1) in a 144-ha research area located in the...

Modeling forest growth and production is a major challenge for forest managers due to the large number of variables involved and the importance of the generated estimates for decision making in the forestry enterprise. Several statistical and artificial intelligence methods can be used to verify...

This article aimed to present a brief history of the Graduate Program in Forestry Engineering (PPGEF) of the Federal University of Paraná in this year of the fiftieth anniversary of its creation. Starting from the minutes, records and reports of the founding professors, it was possible to...
