“…Guazuma ulmifolia, Machaerium stipitatum, Croton floribundus, and Aloysia virgata were the species with the highest importance value. Machaerium stipitatum is considered an early secondary species [37] , whereas G. ulmifolia, C. floribundus, and A. virgata are regarded as pioneers [38] . The fact that half of the stems sampled corresponded to pioneer and early secondary species indicates that the community studied is in a successional stage.…”

Studies on composition and structure generate crucial information for characterizing plant communities and planning conservation actions. There are still substantial knowledge gaps in Brazilian protected areas, preventing design programs to mitigate biodiversity loss. This is the case of the National Forest of Ipanema (Ipanema NAFO) in São Paulo state, Brazil, where plant diversity remains uncalculated. To help fill this gap, in 1-ha of a seasonal semideciduous forest (SSF) stand on the Araçoiaba hill, the authors sampled all woody stems with dbh ≥ 5 cm in a total of 103 dead and 1,301 living plants representing 65 species, 57 genera, and 31 families. The number of species and families was lower than old-growth SSF and, together with the land-use history, which suggests the community is a secondary stand. The initial species Guazuma ulmifolia, Machaerium stipitatum, Croton floribundus, and Aloysia virgata totalized 50% of the living stems, whereas 37% of the other species summed up only 1.8%. The high abundance of these initial species and the presence of the climax species Cariniana legalis, Holocayx balansae, Myroxylon peruiferum, Zanthoxylum caribaeum and others indicate that the community is in an intermediate to advanced successional stage. Three species are considered vulnerable to extinction and 27 of least concern. Ipanema NAFO is an important conservation unit, sheltering some plants vulnerable to extinction and others locally rare. This study adds to other few studies about the flora of Ipanema NAFO, helping to estimate its biodiversity and planning conservation actions. Additionally, it is a source for defining reference values for ecological restoration in the Atlantic forest.

“…For this reason, techniques of vegetative propagation can be an alternative for the production of this and other forest species for use in the ecological restoration of degraded areas, as well as for silvicultural purposes in food production, and in the rescue and conservation of genetic resources (Ledig et al, 1992;Erikisson and Fröborg, 1996;De Oliveira et al, 2020;Viveiros et al, 2021).…”

Vegetative propagation is an alternative for the production of seedlings of native tree species such as Schinus terebinthifolia that presents a high predation rate on its seeds. In order to develop vegetative propagation technology, different concentrations of indolebutyric acid (IBA) were tested in the rooting of apical and intermediate minicuttings of Schinus terebinthifolia. The 2x4 factorial experimental design involved two types of minicuttings (apical and intermediate) and four dosages of the hormone IBA (0, 1000, 2000, and 4000 mg. L-1). The percentages of survival and rooting were evaluated. The intermediate minicuttings (37% and 35%) showed significantly greater survival than the apical cuttings (22% and 9%) respectively at 30 and 60 days, regardless of the IBA concentration. Among the rooting averages at 60 days obtained in the different concentrations of IBA, the treatment of 4000 mg. L-1 generated the highest results (9% for apical and 35% for intermediate). The vegetative propagation by minicuttings of Schinus terebinthifolia demonstrated the viability of intermediate minicuttings with high rooting associated with the highest concentration of IBA.

Bibliometric and literature synthesis on assisted natural regeneration: an evidence base for forest and landscape restoration in the tropics

Assisted Natural Regeneration (ANR) is a set of restoration strategies and interventions primarily based on natural regeneration, aimed at accelerating succession and providing multiple benefits in degraded ecosystems and landscapes. These strategies have the potential to significantly contribute to global Forest and Landscape Restoration efforts. However, ANR faces challenges due to limited recognition, support, and formal integration into relevant sectors and restoration policies, particularly in tropical regions. The dearth of evidence-based syntheses further compounds these challenges. To address this gap, a bibliometric analysis of selected scientific publications on ANR (n = 208) from 1987 to 2023 was conducted, using Web of Science and Google Scholar databases. A systematic review was undertaken, using a subset of original research articles (n = 44), to synthesize published data on interventions, contexts, costs, and benefits of ANR and to identify major knowledge gaps. Analysis of bibliometric metadata revealed an increasing annual output of ANR publications in over 80 journals, encompassing various document types and authors from over 40 countries. Despite ANR’s formal emergence in the Philippines, Brazil has taken the lead in both its research and implementation, and international collaboration in ANR research has grown. While ANR research focused mostly on ecosystem services and ecological outcomes, social aspects have been poorly studied. Diverse ANR interventions align not only with ecological restoration but also with integrated land management, biodiversity conservation, forest and landscape restoration, and forest management. The cost-effectiveness of ANR implementation, especially in restoration for carbon storage, exhibited considerable variability when compared to active tree planting, and varied with intervention types, time, land use history, and long-term costs. This synthesis provides critical insights and evidence to enhance the effective integration of ANR into restoration and reforestation programs and policies.
