“…Our results of a positive effect of sampling year and restoration age confirm the prediction of the successional theory that ecosystem attributes increase progressively with age, and support observations from previous studies (e.g. Marques et al ; Bertacchi et al ). For instance, Capers et al () found that diversity of seedlings increased with age in tropical forests in Costa Rica over a 5‐year period for sites initially 5–26 years old.…”

The status of woody seedling colonization gives clues about the self‐sustainability of restored forests, a tenet of restoration success. Little is known about woody seedling colonization in restored afrotropical forests. We evaluated effects of restoration methods (active vs. passive), sampling year, restoration age, and distance from old‐growth forests on seedling colonization in restored afrotropical moist forests. Seedlings were measured in 2011 and 2014 in 71 clusters of 284 permanent sampling plots (12.6 m2 each) in actively (initially 3–16 years old) and 21 clusters of 63 plots in passively restored forests (initially 16 years old) in Kibale National Park, western Uganda. Seedlings were also measured in nearby old‐growth forests in three clusters of five plots in 2014. We determined species diversity, richness, abundance per plot, and species composition as measures of seedling colonization in restored and old‐growth forests. We found that diversity, richness, and abundance of seedlings were significantly higher in passively than actively restored forests. Diversity and richness but not abundance significantly increased between sampling years and with restoration age. Distance from old‐growth forests did not significantly affect diversity, richness, and abundance. Species composition of actively and passively restored forests was different from that of old‐growth forests after 19 years since restoration started. Our results show that passive restoration should be the preferred method for recovering afrotropical forests, and highlight the effect of continued management on biodiversity of restored forests.

“…In southern tropical Atlantic forest with mean annual precipitation over 2000 mm/yr, basal area recovery is slower (biomass estimates are not available) and takes closer to 35 or 50 yr to attain mature levels of biomass (Marques et al . , Martins et al . ).…”

“…Toward the northern limit of the Atlantic forest range, in a moist tropical secondary forest (mean annual precipitation 1687 mm/yr), regeneration rates appear rapid, with 20-yr-old forest attaining 83 percent of mature forest levels of basal area (do Nascimento et al 2014). In southern tropical Atlantic forest with mean annual precipitation over 2000 mm/yr, basal area recovery is slower (biomass estimates are not available) and takes closer to 35 or 50 yr to attain mature levels of biomass (Marques et al 2014, Martins et al 2015. In southern seasonally dry tropical Atlantic forest, regeneration is also slow and potentially arrested by shrub species (Robinson et al 2015).…”

Landscape‐scale lidar analysis of aboveground biomass distribution in secondary Brazilian Atlantic Forest

et al. 2018

Secondary forests account for more than half of tropical forests and represent a growing carbon sink, but rates of biomass accumulation vary by a factor of two or more even among plots in the same landscape. To better understand the drivers of this variability, we used airborne lidar to measure forest canopy height and estimate biomass over 4529 ha at Serra do Conduru Park in Southern Bahia, Brazil. We measured trees in 30 georeferenced field plots (0.25‐ha each) to estimate biomass using allometry. Then we estimated aboveground biomass density (ABD) across the lidar study area using a statistical model developed from our field plots. This model related the 95th percentile of the distribution of lidar return heights to ABD. We overlaid this map of ABD on a Landsat‐derived forest age map to determine rates of biomass accumulation. We found rapid initial biomass regeneration (~6 Mg/ha yr), which slowed as forests aged. We also observed high variability in both height and biomass across the landscape within forests of similar age. Nevertheless, a regression model that accounted for spatial autocorrelation and included forest age, slope, and distance to roads or open areas explained 62 and 77 percent of the landscape variation in ABD and canopy height, respectively. Thus, while there is high spatial heterogeneity in forest recovery, and the drivers of this heterogeneity warrant further investigation, we suggest that a relatively simple set of predictor variables is sufficient to explain the majority of variance in both height and ABD in this landscape.

“…O preenchimento das espécies originadas por sementes foi realizado principalmente por espécies pioneiras, com 77,7% do número de indivíduos e 72,6% das espécies, como ocorre em clareiras naturais grandes (Martins e Rodrigues, 2002;Martins et al, 2004.). Tais porcentagens mostram diferenças de predominância de grupos sucessionais indicando estágios sucessionais e comunidades diferentes, como observado por Marques et al (2014), que se substituem no processo sucessional, conforme Tabarelli e Mantovani (1999); Finegan e Delgado (2000) e Guariguata e Ostertag (2001).…”

Na Serra da Cantareira, houve o corte da foresta para a instalação de torres de transmissão de energia elétrica, formando clareiras que variaram de 120 m2 a 286 m2 , totalizando 0,2 ha. O objetivo deste trabalho foi caracterizar a estrutura do componente arbustivo-arbóreo nestas clareiras, analisando os componentes dos indivíduos originados por sementes e por brotação. Foram amostrados 1.732 indivíduos com altura superior a 1,30 m, pertencentes a 140 espécies e 44 famílias. Destes, 1.336 indivíduos (77,2%) e 83 espécies originaram-se por sementes, com Densidade de 6.680 ind./ha e Dominância de 6 m2 /ha; e 396 indivíduos (22,8%) e 78 espécies por brotação, com Densidade de 1.980 ind./ha e Dominância de 1,2 m2 /ha. Para os indivíduos originados por sementes, Croton macrobothrys, Piptocarpha macropoda, Trema micrantha, Solanum mauritianum e Sessea brasiliensis apresentaram os maiores Valores de Importância, e para aqueles originados por brotação, Cupania oblongifolia, Coffea arabica, Sessea brasiliensis, Croton foribundus e Guarea macrophylla. A similaridade forística entre os dois componentes foi baixa (15%), evidenciando a existência de dois conjuntos forísticos diferentes. Para os indivíduos que se estabeleceram por sementes predominaram espécies Pioneiras (72,6% das espécies, 77,7% dos indivíduos), diferindo dos indivíduos que se mantiveram por brotação, em que predominaram Secundárias iniciais e Umbróflas com 55,1% e 28,5% dos indivíduos e 49,4% e 22,1% das espécies, respectivamente, mostrando a substituição de espécies, famílias e grupos sucessionais predominantes em comparação com a foresta original.
