Understanding the vulnerability of tree species to anthropogenic threats is important for the efficient planning of restoration and conservation efforts. We quantified and compared the effects of future climate change and four current threats (fire, habitat conversion, overgrazing, and overexploitation) on the 50 most common tree species of the tro...

Forest restoration projects involving active planting should prioritize species that are useful to local communities, while also considering species' threat status and resistance to local stress factors, but scientific knowledge on these criteria is scarce, especially in understudied tropical ecosystems. We hypothesized that local ecological knowle...

At the start of the UN Decade of Ecosystem Restoration (2021 – 2030), the restoration of degraded ecosystems is more than ever a global priority. Tree planting will make up a large share of the ambitious restoration commitments made by countries around the world, but careful planning is needed to select species and seed sources that are suitably ad...
Article
Remote sensing-based approaches are important for evaluating ecosystem degradation and the efficient planning of ecosystem restoration efforts. However, the large majority of remote sensing-based degradation assessments are trend-based, implying that they can only detect degradation that occurred after medium or high-resolution satellite imagery be...
Article
Tree-based forest landscape restoration interventions require knowledge on the suitability and origin of seed sources and planting material. A common recommendation is to select locally sourced material based on the assumption that it is well adapted to local environmental conditions and to avoid introduction of maladapted genes. However, faced wit...

Modern food systems push agriculture to focus on a small number of commercial crops, while there is a very large diversity of untapped edible plants that could be used to address food security and nutrition. Poor and monotonous diets are closely linked to the complex burden of multiple forms of malnutrition and dietary risk. In some contexts, such...

Governments are updating national strategies to meet global goals on biodiversity, climate change and food systems proposed in the Convention on Biological Diversity post-2020 framework and agreed at the United Nation’s Climate Change Conference (COP26) and Food Systems Summit (UNFSS). This represents a unique and crucial opportunity to integrate a...

Question: Anthropogenic disturbances severely affect dryland forests worldwide, but their effects on woody species population structure and long-term persistence remain poorly understood. Location: The research was conducted in Desa'a, a dry Afromontane forest in northern Ethiopia, Tigray region. Aims: Woody species diversity, extinction debt, rec...

Climate change and other anthropogenic threats are increasingly imperilling the diverse biomes of Central Africa, which are globally important for biodiversity, carbon storage and people's livelihoods. The objectives of this paper were to: (i) map the vulnerability of 100 socio-ecologically important priority tree species in Central Africa to clima...
Article
Understanding the impact of multiple anthropogenic threats on tree species is urgently needed for estimating population decline and enabling coordinated and efficient conservation actions. We applied a spatially explicit framework to assess the vulnerability of three highly valuable Asian rosewood species (Dalbergia cochinchinensis, D. cultrata, D....
Article
Pongamia (Millettia pinnata) has recently gained attention as a novel biofuel feedstock. However, yield levels and dynamics of this largely undomesticated species remain poorly understood. This study addresses the critical lack of scientific evidence by collecting primary seed and oil yield data from 81 pongamia trees across a range of cultivation...

Tree diversity in Asia's tropical and subtropical forests is central to nature-based solutions. Species vulnerability to multiple threats, which affects the provision of ecosystem services, is poorly understood. We conducted a region-wide, spatially explicit vulnerability assessment (including overexploitation, fire, overgrazing, habitat conversion...

Achieving multi-million-hectare commitments from countries around the world to restore degraded lands in resilient and sustainable ways requires, among other things, huge volumes of tree planting material. Seed systems encompassing all forest reproductive material (e.g., seeds, cuttings, stakes, and wildings), are key to ensuring that sufficient pl...

Aim Cacao (Theobroma cacao L.) is expected to be vulnerable to climate change. The objectives of this study were to (a) assess the future impact of climate change on cacao in Peru and (b) identify areas where climate change‐tolerant genotypes are potentially present. Location Peru. Methods Drawing on 19,700 to and1,200 presence points of cultivat...

Natural regeneration of trees may provide a cost‐effective way to restore degraded tropical dry forests, but the factors predominantly affecting natural regeneration success are poorly understood. We performed a multifactor analysis of natural regeneration in an Afromontane forest in Northern Ethiopia. Inventory plots of 400 m2, each with a nested...

The tropical dry forests of NW Peru are heavily shaped by the El Niño Southern Oscillation (ENSO), where especially El Niño brings rain to arid to semi-arid areas. However, the resulting effects on biodiversity patterns remain largely unknown as well as the effect of environmental variables on the floristic composition under varying rainfall patter...

Vanilla, an expensive but popular spice used in many industries, faces problems related to its supply. Some of these problems are due to the fact that vanilla cultivation is based on clonal material of a single species (Vanilla planifolia) and is dominated by just a few countries located outside the native growing areas of aromatic vanilla species,...

Capacity Development in the Tree Seed Supply Systems
Project
This project aims to offer site-specific data and recommendations to improve cacao cultivation in Latin America, responding to multiple threats such as climate change and heavy metal accumulation, and making better use of the existing diversity of cacao genetic resources and associated biodiversity. Overall, we plan to share all our research results through the online platform www.cacaodiversity.org. The platform will be expanding both geographically and thematically in the near future.

At the dawn of the UN Decade of Restoration, tree-based restoration of degraded areas has become a global priority. An important, but often overlooked, aspect of ensuring the long-term success of restoration projects relates to the selection of appropriate species and seed sources, at least for active restoration activities that involve tree planting. As a minimum condition, the selected planting material should (i) correspond to the restoration objectives, (ii) be well adapted to survive and thrive under the degraded site conditions, and (iii) have sufficient genetic diversity to ensure the potential to adapt to changing conditions in the future. Here we present a scalable map-based online tool available at www.diversityforrestoration.org, which is intended to assist restoration practitioners with the identification of appropriate tree species and seed sources. Originally developed for the tropical dry forests of Colombia, the tool has now been outscaled to the tropical dry forests of northwestern Peru and southern Ecuador, and further outscaling to Burkina Faso and Cameroon is underway. Decision making combines information on (i) suitability modeling under current and future climate conditions; (ii) restoration objectives, including agroforestry and commercial uses; (iii) locally prevailing stress conditions; (iv) functional trait diversity of tree species; and (v) the genetic quality of seed sources. Acknowledging that restoration has different, audience-specific meanings and interpretations, our tool is intended to support the decision making of anyone interested in planting trees for whichever purpose.
