“…Our partners, researchers and practitioners from Latin America, will take a leading role in this work package. For instance, while we selected our exemplar IAS because of their importance in the partner countries, other species such as Pinus elliottii and P. taeda are transforming grasslands in northern Argentina and southern Brazil (Zenni and Simberloff 2013;Brandes et al 2019, Durigan et al 2007; Box 1). We will carry out workshops with foresters to explore plausible management scenarios that might be applicable for data-poor species, as well as future scenarios involving synergies between IAS.…”

Invasive Alien Species (IAS) threaten biodiversity, ecosystem functions and services, modify landscapes and impose costs to national economies. Management efforts are underway globally to reduce these impacts, but little attention has been paid to optimising the use of the scarce available resources when IAS are impossible to eradicate, and therefore population reduction and containment of their advance are the only feasible solutions. CONTAIN, a three-year multinational project involving partners from Argentina, Brazil, Chile and the UK, started in 2019. It develops and tests, via case study examples, a decision-making toolbox for managing different problematic IAS over large spatial extents. Given that vast areas are invaded, spatial prioritisation of management is necessary, often based on sparse data. In turn, these characteristics imply the need to make the best decisions possible under likely heavy uncertainty. Our decision-support toolbox will integrate the following components: (i) the relevant environmental, social, cultural, and economic impacts, including their spatial distribution; (ii) the spatio-temporal dynamics of the target IAS (focusing on dispersal and population recovery); (iii) the relationship between the abundance of the IAS and its impacts; (iv) economic methods to estimate both benefits and costs to inform the spatial prioritisation of cost-effective interventions. To ensure that our approach is relevant for different contexts in Latin America, we are working with model species having contrasting modes of dispersal, which have large environmental and/or economic impacts, and for which data already exist (invasive pines, privet, wasps, and American mink). We will also model plausible scenarios for data-poor pine and grass species, which impact local people in Argentina, Brazil and Chile. We seek the most effective strategic management actions supported by empirical data on the species’ population dynamics and dispersal that underpin reinvasion, and on intervention costs in a spatial context. Our toolbox serves to identify key uncertainties driving the systems, and especially to highlight gaps where new data would most effectively reduce uncertainty on the best course of action. The problems we are tackling are complex, and we are embedding them in a process of co-operative adaptive management, so that both researchers and managers continually improve their effectiveness by confronting different models to data. Our project is also building research capacity in Latin America by sharing knowledge/information between countries and disciplines (i.e., biological, social and economic), by training early-career researchers through research visits, through our continuous collaboration with other researchers and by training and engaging stakeholders via workshops. Finally, all these activities will establish an international network of researchers, managers and decision-makers. We expect that our lessons learned will be of use in other regions of the world where complex and inherently context-specific realities shape how societies deal with IAS.

“…Several terminologies have stemmed from the concept of dendrochronology, depending on the issues to be studied. This includes terms such as dendroclimatology for particularly for looking into past climate variability [17,18], dendroecology which is the broader science field for drawing environmental information from tree rings such as fires and insect outbreaks [19,20], dendrogeomorphology which is a subfield of dendroecology and focuses on geomorphological processes such as flooding, rock fall activities or landslides, and river related vegetation processes [21,22], and dendroarcheology which focuses on dating wooden material from archaeological sites [23,24]. Decdrochronology has also been used for studying snow avalanches, volcanoes eruptions and earthquakes [25].…”

Dendrochronology in Namibia: A Review

More than 64% of Namibia's land is occupied by the savanna ecosystems which are vulnerable to climate change and variability. These ecosystems partly consist of forest ecosystem patches which are prime sources of many livelihoods in the country. The effects of climate change are likely to drive the majority of the country's population to poverty if these resources are not sustainably managed. Therefore an understanding of forest dynamics and their responses to climate is important. Dendrochronology is a study that provides time-series data of climate change and variability, and the responses of trees to such changes. The data are used to reconstruct past events of climate and also to forecast possibilities. Dendrochronological studies have been carried out in Namibia, however, a review of such studies is lacking. This study thus aimed at closing this gap and carried out a literature review on the dendrochronological studies in Namibia. The review showed that the field of dendrochronology is relatively new and has been less applied in Namibia. There is a need for further dendrochronological studies in order to understand how the country can adapt better under the current and forecasted climate regimes. A focus on the marginal forests, encroachers and trees that are of indigenous use, is recommended. In cases of the absence of clear ring formation, which might be the case in arid to hyper arid, the use of staple isotopes is recommended.

“…Based on dendrochronological research, non-native or exotic tree species with distinct growth rings can be analyzed (Closset-Kopp et al 2011;Nuñez and Paritsis 2018;Brandes et al 2019;Nogueira et al 2019). Recent research has shown that the analysis of tree rings may also be applied to understanding growth patterns of non-native species, providing useful information on the introduction, invasiveness, and spatial-temporal distribution, although mainly in temperate environments (Closset-Kopp et al 2011;Kasson et al 2013;Nuñez and Paritsis 2018).…”

However, there are few studies with similar approaches in Brazilian tropical environments (Brandes et al 2019;Nogueira et al 2019), which mainly concentrated in the development of chronologies with native species (Callado et al 2001;Fontana et al 2018;Lisi et al 2008;Aragão et al 2019). Hence, a study of the growth trajectories of invasive species could contribute to understanding what benefits their establishment in new environments.…”

Tropical dendrochronology applied to invasive tree species in the Brazilian Atlantic Forest

et al. 2019

View full text Add to dashboard Cite

The Atlantic Forest is one of the largest and most biodiverse rainforests of South America but anthropogenic activities are drastically changing these landscapes. The invasion of alien or exotic species is one of the greatest threats to biodiversity. There are few studies of invasive species in tropical Brazilian ecosystems. This research examines growth and ecological aspects of Syzygium cumini and Clitoria fairchildiana, two invasive tree species in the Pedra Branca State Park, an Atlantic Forest remnant in southeastern Brazil. Both species were successfully dated, indicating an average age of 58 and 31 years, respectively. A positive relationship between growth and precipitation of the previous growing season suggests an ecological adaptive strategy, which could be facilitating their invasion into the environment. Cumulative growth diameter curves indicate slow and fast growth rates for S. cumini and C. fairchildiana, respectively. Growth release episodes detected in the tree rings indicate increased anthropogenic disturbances over the last 50 years.
