“…This oscillation is obvious on a scale of small forest patches because of local sylvigenetic cycles, but when it occurs over wider areas, climatic fluctuations may also be important (Phillips & Gentry 1994). Disturbance of various kinds is commonly the chief cause of forest instability and this may involve floods, windstorms, fire, landslides, drought, and human intervention (Condit et al 1995, Laurance et al 1998, Whitmore & Burslem 1998, Gomes et al 2003, Damasceno Junior et al 2004, Werneck & Franceschinelli 2004. This poses the question of whether the imbalance found for the studied forest resulted either from climatic fluctuation or disturbance by the great flood of 1992.…”

“…Other disturbances, operating on larger scales, such as forest felling and fragmentation, fire outbreaks, hurricanes, landslides, and river floods, are also known to have a strong effect on forest dynamics and, as a result, on the composition and structure of tree communities (Whitmore & Burslem 1998). The effects of river flood disturbances to tropical forests dynamics are still poorly studied (Damasceno Junior et al 2004, Guilherme et al 2004.…”

“…Species-richer "várzea" forests develop on more stable sites, where floods are shorter or sedimentation rates lower (Junk 1990, Metzger et al 1997. Notwithstanding, infrequent but catastrophic floods can also have a considerable effect on the structure of plant communities of riverine forests (Damasceno Junior et al 2004). …”

-(Tree population and community dynamics in a Brazilian tropical semideciduous forest). The dynamics of the tree community and 30 tree populations were examined in an area of tropical semideciduous forest located on the margin of the Rio Grande, SE Brazil, based on surveys done in 1990 and 1997 in three 0.18 ha plots. The main purpose was to assess whether variations in dynamics were related to topography and the effects of a catastrophic flood in 1992. Rates of mortality and recruitment of trees and gain and loss of basal area in two topographic sites, lower (flooded) and upper (non-flooded), were obtained. Projected trajectories of mean and accelerated growth in diameter were obtained for each species. In both topographic sites, mortality rates surpassed recruitment rates, gain rates of basal area surpassed loss rates, and size distributions changed, with declining proportions of smaller trees. These overall changes were possibly related to increased underground water supply after the 1992 flood as well as to a c. 250-year-old process of primary succession on abandoned gold mines. Possible effects of the 1992 flood showed up in the higher proportions of dead trees in the flooded sites and faster growth rates in the flood-free sites. Species of different regeneration guilds showed particular trends with respect to their demographic changes and diameter growth patterns. Nevertheless, patterns of population dynamics differed between topographic sites for only two species.

Dinâmica de uma comunidade arbórea após enchente em fragmentos florestais no sul de Minas Gerais

RESUMO -Com o objetivo de avaliar o impacto de uma enchente de grandes proporções sobre os indivíduos arbóreos, foi realizada, no ano de 2007, a avaliação de uma área aluvial localizada em São Sebastião da Bela Vista, MG, onde foram amostrados cinco fragmentos aluviais e uma floresta ciliar, inventariados inicialmente em 2005. Os resultados indicaram que, após a enchente, a dinâmica no curto-prazo foi caracterizada por taxa de mortalidade superior à de recrutamento e taxa de perda maior do que a de ganho em área basal. Entretanto, a estrutura da comunidade não foi alterada, pois a frequência de indivíduos sobreviventes e de mortos nas classes diamétricas foi proporcional ao número inicial de indivíduos em cada classe. Os resultados permitiram concluir que, apesar de não terem sido observadas alterações na estrutura diamétrica, a dinâmica da comunidade arbórea refletiu o distúrbio causado pela enchente.Palavras-chave: Dinâmica florestal, Distúrbios naturais e Fragmentos florestais.

Ecological restoration has widely variable outcomes from successes to partial or complete failures, and there are diverse perspectives on the factors that influence the likelihood of success. However, not much is known about how these factors are perceived, and whether people's perceptions match realities. We surveyed 307 people involved in the restoration of native vegetation across Australia to identify their perceptions on the factors influencing the success of restoration projects. We found that weather (particularly drought and flooding) has realized impacts on the success of restoration projects, but is not perceived to be an important risk when planning new projects. This highlights the need for better recognition and management of weather risk in restoration and a potential role of seasonal forecasting. We used restoration case studies across Australia to assess the ability of seasonal forecasts provided by the Predictive Ocean Atmosphere Model for Australia, version M24 (POAMA-2) to detect unfavorable weather with sufficient skill and lead time to be useful for restoration projects. We found that rainfall and temperature variables in POAMA-2 predicted 88% of the weather issues encountered in restoration case studies apart from strong winds and cyclones. Of those restoration case studies with predictable weather issues, POAMA-2 had the forecast skill to predict the dominant or first-encountered issue in 67% of cases. We explored the challenges associated with uptake of forecast products through consultation with restoration practitioners and developed a prototype forecast product using a local case study. Integrating seasonal forecasting into decision making through (1) identifying risk management strategies during restoration planning, (2) accessing the forecast a month prior to revegetation activities, and (3) adapting decisions if extreme weather is forecasted, is expected to improve the establishment success of restoration.
