“…The rapid development of stump sprouts was more obvious in the early stage after logging, which was confirmed by other studies on other oaks (Lockhart and Chambers, 2007;Xue et al, 2013;Rong et al, 2013). Stump sprouting is a process that consumes energy and resources, as reflected by the sharp decline in starch content in the root system of the stump after sprouting (Bowen and Pate, 1993;Bell and Ojeda, 1999), and decrease in carbohydrate and nutrients in the stump and root system with increasing harvesting age (Lockhart and Chambers, 2007). Midgley (1996) proposed a trade-off between sprouting and height growth for stump sprouts; the production of new sprouts may influence the height increment of old sprouts.…”

Aim of study: Quercus variabilis (Chinese cork oak) reproduces asexually and sexually. This study aimed to determine the status and growth of asexual and sexual recruits of Q. variabilis in different forest recovery stages.Area of study: Three selective logged stands and one unlogged stand in Q. variabilis forest, Shaanxi Province, China. Material and methods:Origin, number, basal diameter, height and size structure of Q. variabilis shoots (height ≤200 cm) were investigated in the plots of 5, 10, and 20-years post-logging stands and unlogged stand. Effects of recovery stage on the density and growth of the three original recruits (stump sprouts, stem base sprouts and true seedlings) were analysis by One-way ANOVA.Main results: Sprouts dominated logged stands, whereas true seedlings dominated unlogged stand, stem base sprouts only existed in 20-years post-logging and unlogged stands. Stump sprout density and sprout number per stump both declined with extended post-logging time. True seedlings density increased from 7 to 20 shoots/100 m 2 as the postlogging time extended, and peaked in unlogged stand (94 shoots/100 m 2 ). An ongoing size structure was observed in true seedlings in all stands. Stump sprouts were taller and greater than true seedlings.Research highlights: Stump sprouts contributed more to Q. variabilis forest recovery in the early stage after disturbance. The contribution of true seedlings was limited in the same stage, but they were beneficial for population long-term development. Stem base sprouts were most likely to be a survival strategy rather than a reproductive strategy.

“…In order to support respiratory demands and initiate sprouting, such plants shall have sufficient carbohydrates and nutrients stored in their underground organs (Bowen & Pate 1993). Moreira et al (2012) while studying factors driving intraspecific variability in sprouting, found that resources stored by the plant pre-disturbance can boost its initial ability to sprout and the sprouting vigor and, consequently, its initial post-disturbance ability to acquire new resources.…”

-(The role of root buds in the regeneration of Casearia sylvestris Swartz (Salicaceae) in the Cerrado, São Carlos, São Paulo State, Brazil). The present work describes the fire effects on the population structure of Casearia sylvestris Swartz (Salicaceae). Diameter and height structure as well as spatial distribution patterns of the root sprouts were analyzed pre-and post-fire. The morphology and anatomy of the underground system were also analyzed in order to investigate the nature and origin of sprouts from this system. In this study, a 10-ha of Cerrado area was sampled from February to November 2006; in August, a fire burned roughly 80% of the study area, allowing us to compare the data collected pre-and post-fire. Our findings show that the underground systems consisted of specialized roots and buds originated close to the vascular cambium. The spatial distribution of the root sprouts became clustered pre-and post-fire and most of the root sprouts were concentrated in the first size class, indicating that the sprouts from roots play an important role in the recovery of this species in burnt areas. Keywords: Cerrado, natural fires, sprouting, vegetative reproduction RESUMO -(A função de raízes gemíferas na regeneração de Casearia sylvestris Swartz (Salicaceae) no Cerrado, São Carlos, SP, Brasil). Este artigo descreve os efeitos de incêndio na estrutura populacional de Casearia sylvestris Swartz (Salicaceae). Foram analisados a estrutura de diâmetro e altura e o padrão de distribuição espacial antes e após o fogo. Além disso, foi realizada a caracterização morfológica e anatômica do sistema subterrâneo para determinar a natureza e origem dos brotos oriundos desse sistema. Neste estudo foram amostrados 10 ha de fevereiro a novembro de 2006, em agosto, um incêndio queimou cerca de 80% da área de estudo, permitindo a comparação de dados coletados antes e após este evento. Foram verificados que os sistemas subterrâneos gemíferos são de natureza radicular e que os brotos se originam próximo ao câmbio vascular. A distribuição espacial dos brotos de raiz tornou-se agregada após o incêndio e houve maior concentração de brotos de raiz na primeira classe de tamanho indicando que esses brotos são responsáveis pela recomposição dessa espécie em áreas queimadas.

“…The reason for the more rapid recovery response of this species in comparison with the resprouter E. australis was not clear, and did not conform to that recorded in burned heathland of similar characteristics (Calvo et al, 1998). On comparing two congeneric species from Western Australia, much higher initial growth was found in the seeder species than in the resprouter one, but only when recruiting from seeds; the older resprouter plants had a faster initial recover presumably because of their greater root reserves (Hansen et al, 1991;Bowen and Pate, 1993). On the other hand, Conard et al (1995) found that seeded grass competed with the spontaneous herbaceous species, but not with the chaparral shrubs in Southern California.…”

Effects of sowing native herbaceous species on the post-fire recovery in a heathland

Erica australis heathlands in León province (NW Spain) have high resilience to disturbances and their post-fire recovery is very fast. The risk of soil erosion is high in the first few months after fire. The aim of this study is to investigate the effects on post-fire succession of sowing grass (Agrostis capillaris and Festuca rubra) and legume (Lotus corniculatus) seeds in a heathland burned by a summer wildfire, and to determine the most suitable native herbaceous species combination for protecting the soil in the first few phases of recovery. Fifteen permanent 4 m 2 plots are established in the burned area; four treatments and a control (unsown) are applied, each with three replicates. Three similar unburned plots are also considered (unburned control). Total cover is significantly higher in the sown plots in relation to the control in the first few months after sowing, but there are no differences after 18 months. Lotus corniculatus appears only in the first year and has no effect on the total cover. F. rubra appears earlier than Agrostis capillaris, but decreases significantly in cover after 18 months. Shrub species have the highest cover in the control plots and the lowest in the Agrostis plots. The correspondence analysis shows that the trend for vegetation in all plots reaches similar species composition by the time of final sampling. The last sampling of sown plots shows greater similarity to the control plots than the sampling of these plots within the first year. The fast initial growth of F. rubra, together with its decrease and subsequent low cover from the second year, make it more preferable than Agrostis capillaris for purposes of soil protection. However, additional research, both species-and site-specific, is necessary, as different responses due to different post-fire conditions and pre-fire species composition can have important implications on community dynamics.
