Forest restoration in Brazil has gained relevance in the country’s environmental agenda, due to the need for forest recovery of large liabilities of existing forests and participation in several international vegetation restoration agreements. However, forest restoration management faces challenges, it being necessary to create a database of species-level performances to increase the success of these projects. The objective was to evaluate the survival and growth of five Atlantic Forest native species (Anadenanthera macrocarpa; Ceiba speciosa; Cytharexyllum myrianthum; Hymenaea courbaril; and Peltophorum dubium) in plastic bags (1177 cm3) and tubes (180 cm3). Ninety seedlings (18 of each species) were planted per container. Plant performance in the field consisted of evaluating the increase in the diameter and height of seedlings of the native forest species. Diameter at soil level (DSL) and plant height (H) were measured at 42 months after transplanting, and the monthly periodic increments (MPI) of the DSL and H were calculated. Plant survival (SV) of seedlings was affected by the type of container, registering the highest SV rates in those planted in plastic bags. Cytharexyllum myrianthum and H. courbaril presented high SV rates in tubes. The growth rate of the species at 42 months differed according to the containers tested. Cytharexyllum myrianthum presented the lowest SV rates (16.7–27.8%), regardless of the container used in this experiment. Ceiba speciosa was sensitive to the reduction in size of the container, showing low SV in tubes (27%) compared with plastic bags (61%); i.e., this species did not tolerate conditions with root growth restriction. Anadenathera macrocarpa and H. courbaril showed no differences in SV, regardless of the container used. The results assist the production of native species of the Atlantic Forest, reinforcing the need to understand performances in the field at the species level.

ABSTRACT The objective of this study was to evaluate organic substrates in the production of canafistula (Peltophorum dubium) (Spreng.) Taub, cutieira (Joannesiaprinceps Vell.), jatoba (Hymenaea courbaril L.) and rubber tree (Hevea brasiliensis M. Arg.) seedlings, native trees with potential use in forest restoration programs. The design was completely randomized with 10 substrate formulations with 4 repetitions of 3 plants for the four species. The evaluated substrates consisted of soil, bovine manure (BM), poultry manure (PM), chemical fertilizer (CF) and sand, in different proportions. The experiment was concluded at the end of 180 days for canafistula, cutieira and rubber and 210 days for jatoba. At the end of these periods, the root (RDM), shoot (SDM) and total (TDM) the dry matters of the seedlings were determined. Quantification of AMF spores and normalization between samples through SPORES/RDM correction were also performed. The Scott-Knott test at 5% probability was applied. Regarding biomass production, only canafistula had significant difference among the tested substrates. In relation to sporulation, the highest values were observed in cutieira and rubber tree in substrate containing PM. The substrates composed of 40 or 50% soil + 20% sand + 30% or 40 PM for canafistula; 50% soil + 20% sand + 30% PM for cutieira; and for jatoba and rubber tree 60% soil + 20% sand + 20% PM, enabled the best results in terms of biomass production in seedlings and AMF sporulation.

A diversidade total de espécies florestais da Mata Atlântica produzidas nos viveiros do Estado do Rio de Janeiro é baixa, assim como a diversidade média, já que mais da metade dos viveiros trabalha com uma listagem de 50 ou menos espécies, número insuficiente considerando a diversidade de espécies florestais presentes nas diferentes formações vegetais do estado.Palavras-chave: Mudas florestais; restauração florestal; Mata Atlântica. AbstractAssessment of diversity of native species produced in forest nurseries of Rio de Janeiro State. The objective of this paper was to evaluate the diversity of native species produced by nurseries in the State of Rio de Janeiro. The diagnostic and survey were conducted during the months of February, March and April of the year 2010, the research included all nurseries that produced seedlings of Atlantic Forest species. The fieldwork consisted of visits to the 70 surveyed nurseries, in which a list of the species produced in the nursery was requested and the seedling production manager was interviewed, filling in a questionnaire covering various topics related to seedlings production. We observed 277 forest species native from the Atlantic Forest produced in the nurseries. In average, the nurseries produce 56 different native species. The total diversity of native species produced in the State of Rio de Janeiro is low, as well as the mean diversity, since more than half of the nurseries work with a list of 50 or fewer species, what is insufficient considering the diversity of forest species that occur in the different vegetation types of the state.Keywords: Forest seedlings; forest restoration; Atlantic Forest.

Conservation And Management

Subject to overexploitation in past centuries, the Atlantic Forest is now strictly protected, including a ban on timber harvesting. However, this strict protection is a very controversial issue. It resulted in a lack of willingness of landholders to conserve and possibly even expand native forest areas. The lack of knowledge on impacts of potential timber-harvesting causes conflicts between conservation and management of the remnant Atlantic Forest. We believe that sustainable forest management, with reduced harvesting impact, has the potential to generate income for the landowners while sustaining important ecological services of the forest. Therefore, we assessed the harvesting impact of a conventional harvesting method (CM) and compared it to an alternative harvesting method (AM) in three different stands. We measured damage intensities of all remnant trees directly after harvesting and two years after harvesting. Tree damages were recorded in three different tree zones (crown, bole and leaning) and rated in three different intensity classes (minor, moderate and severe). Furthermore, we assessed the recovery and mortality rates of each damaged tree two years after harvesting. Improved AM harvesting reduced the impacts on trees with multiple damages, in particular to crown and bole damages combined. There is a strong relationship between steep terrains and crown damage. High mortality rates were related to stands with a high density of smaller trees and also to trees with leaning damage. Moreover, completely recovered trees were related to trees with light bole damage.

The regularization of rural properties in the molds of the New Forest Code depends on the silvicultural study of the native species of the Brazilian biomes. The objective of this study was to evaluate the initial growth of five native tree species of the Atlantic Forest, with a view to their use in forest restoration projects. The following species were produced in the nursery, planted in the field, and evaluated for performance: Araucaria angustifolia, Mimosa scabrella, Trichilia claussenii, Schizolobium parahyba, and Cordia trichotoma. These species were distributed in two different areas, based on the randomized block experimental design. In experiment 1, the species A. angustifolia, M. scabrella, and C. trichotoma were distributed in three randomized blocks, each composed of 11 plants of each species. In experiment 2, the species A. angustifolia, M. scabrella, T. claussenii, and S. parahyba were distributed in three randomized blocks, each one composed of five plants of each species. In general, S. parahyba and M. scabrella showed faster development than the other species and, in this regard, are promising candidates for forest areas constitution or reconstitution in which there is interest in obtaining economic returns in less time. Araucaria angustifolia and T. claussenii showed relatively low development, whereas C. trichotoma showed intermediate development in relation to the other species studied. Despite their differences in performance, all species proved to be suitable for use in reforestation, mainly in the region where the study was developed.

Understanding the behavior of the emergence of native forest seeds is essential to achieve greater successes in forest recovery. Therefore, this study aimed to evaluate the emergence of native forest species (Cassia grandis L.F., Cecropia pachystachya Trec., Enterolobium contortisiliquum (Vell.) Morong, Guazuma ulmifolia Lam., and Libidibia ferrea var. leiostachya (Benth.) L.P.Queiroz.) in riparian areas of the Piauitinga River, in the municipality of Lagarto (state of Sergipe, Brazil). The experiment was carried out in a randomized block design (DBC) with four blocks in triple scheme (4 x 2 x 6): four forest species emerged (Cassia grandis, Enterolobium contortisiliquum, Guazuma ulmifolia, Libidibia ferrea var. leiostachya), with and without treatment to overcome dormancy, evaluated every fortnight for 90 days (6 periods). It was verified by the statistical analysis that the four species that had emergencies interacted in the two treatments used throughout the six evaluation periods. The species, in both treatments, presented a large number of seeds emerged in the first weeks after sowing, reducing over time. The species studied have a characteristic pattern of emergence over time, considering both seeds with and without treatment to overcome dormancy.

A produção de mudas de jatobá (Hymenaea courbaril L.) é essencial para a conservação e restituição ao seu habitat natural. Entretanto a produção de mudas de espécie nativa ainda é pouco estudada. Portanto, o objetivo deste estudo foi avaliar o efeito de diferentes níveis de poda e doses de hidrogel no crescimento inicial de jatobá sob sombreamento. Mudas de jatobá com 90 dias de idade foram usadas no experimento. O delineamento experimental foi o esquema fatorial composto de três níveis de poda radicial (0,0; 25,0 e 50,0%) e cinco doses de hidrogel (0,0; 2,0; 4,0; 6,0 e 8,0 g L-1 de substrato) totalizando 15 tratamentos. Aos 105 dias após o transplantio em casa de vegetação, foram avaliados os parâmetros morfométricos e índices de crescimento. As mudas submetidas à poda radicial de 25,0% apresentaram maior crescimento após transplantio para sacos plásticos. O hidrogel também mostrou efeito positivo nas variáveis morfométricas avaliadas. Efeitos combinados do nível de poda radicial a 25,0% e doses de hidrogel na faixa de 3,0 a 4,0 g L-1 exerceram efeitos positivos no crescimento das variáveis morfométricas. Essas técnicas isoladas ou combinadas podem ser aplicadas por viveiristas para prolongar o tempo de manutenção de mudas de jatobá.Palavras-chave: Polímero hidroabsorvente; déficit hídrico; sistema radicial; Hymenaea courbaril L. EFFECT OF ROOT PRUNING AND HYDROGEL ON GROWTH OF JATOBA SEEDLINGS ABSTRACT:The production of jatoba (Hymenaea courbaril L.) seedlings is essential for the conservation and restitution of their natural habitat. However, the production of seedlings of native species is still little studied. Therefore, the objective of this study was to evaluate the effect of different levels of pruning and hydrogel doses on the initial growth of jatoba under shading. We used jatoba seedlings with 90 days of age in a factorial scheme consisting of three levels of root pruning (0.0, 25.0, and 50.0%) and five hydrogel doses (0.0, 2.0, 4.0, 6.0 and 8.0 g L-1 substrate) totalizing 15 treatments. At 105 days after transplanting in the greenhouse, morphometric parameters and growth rates were evaluated. Seedlings submitted to root pruning of 25.0% showed greater growth after transplanting to plastic bags. The hydrogel also showed a positive effect on the morphometric variables evaluated. The combined effects of 25.0% of root pruning level and doses of hydrogel in the range of 3.0 to 4.0 g L-1 exerted positive effects on the growth of morphometric variables. These isolated or combined techniques can be employed in a nursery to prolong the maintenance time of jatoba seedlings.Keywords: Hydroabsorbent polymer; water deficit; root system; Hymenaea courbaril L.

Priority Areas

The collapse of a mining dam with 62 million cubic meters of mud in the Rio Doce basin resulted in the destruction of whole communities and large areas of Atlantic Forest. As forest restoration activities are among the most costly conservation strategies, prioritization of restoration efforts is crucial. In the present article, we mapped priority areas for forest recovery in a portion of the Rio Doce Basin (DO1) using a GIS-based (geographic information system) multicriteria decision analysis (MCDA) employing the weighted linear combination (WLC) method. Five factors with different weights were taken into consideration according to their level of importance: distance from the drainage network, distance from the native vegetation patches, slope, soil class and precipitation. A map of priority areas was produced where 1.73% of the area was classified as very high priority for forest recovery, while 5.18% of the area was classified as high priority, 57.88% as medium priority, 1.34% as low priority and 0.00% as very low priority. The highest weights were both for the distance from the drainage network and the distance from native vegetation, revealing that areas of permanent preservation and those closer to forest fragments are priority areas for forest recovery. MCDA is a flexible and easy-to-implement method generating maps with suitable solutions for forest recovery. The approach taken can be replicated in regions that require support for decision making in environmental planning, such as the Pantanal biome, which is under considerable pressure from deforestation for the expansion of pastures.

This study characterized the risk-return relationship of sawn wood of different native forest species of the Amazonian area. Specifically, it was determined the risk-return relationship of Ipê, Jatobá, Maçaranduba, Angelim Pedra, Angelim Vermelho and Cumaru boards, in 2003-2007 period. The Geometric Growth Rate of prices of the m³ of boards of each species was admitted as return estimative and the variation coefficient as indicative of risk; the estimated values were plotted in dispersion graphics allowing graphic analysis. It was noticed that their prices float, relatively, in the same way and that Jatobá stands out in attractiveness terms, considering the whole period while the other species presented a coherent relationship among themselves i.e., higher returns associated with high risks. Angelim Vermelho and Maçaranduba stood out for the attractiveness, in an annual perspective.
