Contributions to the harmonization of forest attribute estimates per unit area ...
Vibrans, Alexander Christian; Oliveira, Laio Zimermann; Lingner, Débora Vanessa; Gasper, André Luís deLarge-scale regional or national forest inventories collect field data on sample plots systematically- or randomly-distributed, fully or partially covered by forests. This scientific note addresses differences between a prediction of a forest attribute per unit area that also considers land uses other than forest, and a prediction based only on the forested area of a sample plot. The former approach yields a mo...
MonitoraSC: a new forest cover and land use map of Santa Catarina state
Vibrans, Alexander Christian; Nicoletti, Adilson Luiz; Liesenberg, Veraldo; Refosco, Julio Cesar; Kohler, Luciana Pereira de AraújoA forest cover and land use map provides fundamental information for territorial management, aiming at socioeconomic development, environmental planning and control and protection of natural resources. In this article, a new forest cover map is introduced, using synergies between field data from Santa Catarina Floristic and Forest Inventory (IFFSC) and remote sensing data. Landsat-8 OLI images (2017) were class...
ATLANTIC EPIPHYTES: a data set of vascular and non-vascular epiphyte plants and...
Ramos, Flavio Nunes; Mortara, Sara Ribeiro; Monalisa-Francisco, Nathalia; Elias, João Pedro Costa; Neto, Luiz Menini; Freitas, Leandro; Kersten, RodrigoMade available in DSpace on 2019-10-06T16:16:00Z (GMT). No. of bitstreams: 0 Previous issue date: 2019-02-01; Epiphytes are hyper-diverse and one of the frequently undervalued life forms in plant surveys and biodiversity inventories. Epiphytes of the Atlantic Forest, one of the most endangered ecosystems in the world, have high endemism and radiated recently in the Pliocene. We aimed to (1) compile an extensive...
Inventory of vegetation in early successional stage in the Atlantic rain forest...
Piazza, Gustavo Antonio; Vibrans, Alexander Christian; Oliveira, Laio Zimermann; Liesenberg, VeraldoAbstract: Different areas with vegetation in early stage of secondary succession in the Atlantic Rain Forest (Vale do Itajaí, Santa Catarina) were inventoried. The most abundant species and species diversity were evaluated for each sample plot. Structural parameters were calculated: density (N ha-1), basal area (BAha-1), diameter at breast height (DBH) and total height (Ht). In 0.96 ha of sampled area were regi...
Determining the optimal length of transects for estimating coarse woody debris
Cardoso, Denise Jeton; Vibrans, Alexander Christian; Rezende, Alba Valéria; Pareyn, Frans Germain Corneel; Freitas, Joberto VelosoThe objective of this paper was to evaluate different transect lengths for determination of coarse woody debris on the ground. The data came from 10-meter-long transects, measured during the National Forest Inventory methodology test in the Amazon, Cerrado and Caatinga, and the forest inventory in Santa Catarina State, representing Araucaria Forest and Deciduous Forest. The comparison among the coefficient of v...
Design considerations for tropical forest inventories
McRoberts, Ronald Edward; Tomppo, Erkki Olavi; Vibrans, Alexander Christian; Freitas, Joberto Veloso deForests contribute substantially to maintaining the global greenhouse gas balance, primarily because among the five economic sectors identified by the United Nations Framework Convention on Climate Change, only the forestry sector has the potential to remove greenhouse gas emissions from the atmosphere. In this context, development of national forest carbon accounting systems, particularly in countries with tro...
A cobertura florestal da Bacia do Rio Itajaí: elementos para uma análise histórica
Vibrans, Alexander ChristianTese (doutorado) - Universidade Federal de Santa Catarina, Centro de Filosofia e Ciências Humanas. Programa de Pós-Graduação em Geografia; O problema das enchentes e a ausência de informações quantitativas sobre as florestas da região motivaram este estudo sobre a dinâmica da cobertura florestal da bacia hidrográfica do Rio Itajaí em Santa Catarina. Cheias são eventos naturais e seus efeitos são fortemente infl...
The Floristic and Forest Inventory of Santa Catarina State (IFFSC): methodologi...
Vibrans, Alexander Christian; Sevgnani, Lúcia; Lingner, Débora Vanessa; de Gasper, André Luis; Sabbagh, ShamsThe purpose of this study is to contribute to the discussion on regional and national forest inventories, aiming mainly on aspects of methodos and operational. The Floristic and Forest Inventory of Santa Catarina State (IFFSC) is an initiative of the state government and it was conceived in order to attend requirements of environmental laws. A pilot inventory took place in 2005; then the methodology was fitted...
