Abstract Tropical dry forests are the most threatened tropical terrestrial ecosystem. However, few studies have been conducted on natural regeneration necessary to restore these forests. We reviewed ecology of as a tool disturbed lands. Dry characterized by relatively high number tree species with small, dry, wind‐dispersed seeds. Over small scales, seeds better able colonize degraded areas than vertebrate‐dispersed plants. Small and those low water content less susceptible desiccation,...
Abstract With the increasing need to restore former agricultural lands worldwide and in tropics, particular, it is critical explore different models for how these a cost‐effective manner which best simulates natural forest recovery provides human livelihoods. We propose that agro‐successional restoration, we define as incorporating range of agroecology agroforestry techniques transition phase early could be used more widely overcome socioeconomic ecological obstacles restoring lands. Over...
Large-scale restoration programmes in the tropics require large volumes of high quality, genetically diverse and locally adapted seeds from a number species. However, scarcity native is critical restriction to achieve targets. In this paper, we analyse three successful community-based networks that supply seedlings for Brazilian Amazon Cerrado projects. addition, propose directions promote local participation, legal, technical commercialisation issues up-scaling market with quality social...
Abstract Many degraded ecosystems need active restoration to conserve biodiversity and re‐establish ecosystem function, both highlighted targets of the UN Decade on Ecosystem Restoration proposed EU Nature law. Soil translocation, where plant propagules their associated soil biota are co‐introduced, has increasingly been as a powerful technique for terrestrial ecosystems. However, synthesis effectiveness this method across is lacking. To address how translocation affects success, we...
Topsoil translocation has been used for vegetation restoration throughout the world, but it poorly tested within savannas. This study describes Brazilian savanna (cerrado) regeneration first 3 years following topsoil translocation. The was stripped from 2.5 ha of and spread on 1 an abandoned laterite quarry in Federal District, Brazil. We assessed structure species composition 18 circular plots (3.14/m 2 ) after 5 15 months 30 37 months. In last floristic survey, coverage herbs estimated...
SUMMARY The new Brazilian Forest Code obliges farmers to restore degraded lands on conservation set-asides required all rural properties, known as Permanent Preservation Areas and Legal Reserves. While can do so through agroforestry systems (AFS) improve their livelihoods offset the costs of restoration, these areas must also maintain basic ecological functions. How this be done in practice, however, stills need regulated at state level, but there are few scientific studies Brazil benefits...
Abandonment of agricultural lands promotes the global expansion secondary forests, which are critical for preserving biodiversity and ecosystem functions services. Such roles largely depend, however, on two essential successional attributes, trajectory recovery rate, expected to depend landscape-scale forest cover in nonlinear ways. Using a multi-scale approach large vegetation dataset (843 plots, 3511 tree species) from 22 chronosequences distributed across Neotropics, we show that...
Direct seeding is a promising technique for ecological restoration, but it has been poorly studied in neotropical savannas. Different types of plant cover (no cover, crops, or green manure) and fertilization (unfertilized, synthetic fertilizer, poultry litter) were used to verify if survival growth different tree species after direct could be enhanced by the use any combination these techniques. Seedling emergence, establishment, followed 2 years six savanna sown an agricultural field...
Abstract Aims To address whether seed and seedling functional traits have a significant effect on germination rates survival in direct‐seeding restoration efforts. We tested the hypotheses that: (1) burial only favours emergence of round seeds; (2) straw mulching improves soil moisture prevents invasive grass Urochloa decumbens , promoting establishment native tree seedlings. Location Experimental field, Central Brazil. Savanna, recently dominated by exotic pasture. Methods evaluated effects...
Avoiding, reducing or reversing land degradation will require increased restoration investments, carefully targeted and implemented to maximize environmental, economic social benefits. Our objective was develop a multi-criteria framework assess effectiveness of responses for enhanced use planning by evaluating both direct biophysical socio-economic indirect effects various strategies. The is demonstrated degraded forestland using comprehensive literature review case study in Nepal. results...
Tropical forest canopies are the biosphere's most concentrated atmospheric interface for carbon, water and energy1,2. However, in Earth System Models, diverse heterogeneous tropical biome is represented as a largely uniform ecosystem with either singular or small number of fixed canopy ecophysiological properties3. This situation arises, part, from lack understanding about how why functional properties vary geographically4. Here, by combining field-collected data more than 1,800 vegetation...
Seed dispersal, predation, desiccation and seedling survival are strong bottlenecks that impede tropical forest recovery on abandoned agricultural lands (reviewed in Holl 2002). The ability to resprout after disturbances overcomes these barriers, as those individuals bypass the seed stage have more vigorous shoots than seedlings (Bond & Midgley 2001, Kammesheidt 1999, Kennard et al. Resprouting is a particularly important mechanism dry forests Vieira Scariot 2006). There number of...
Abstract Aims Indicators that can provide information during the early stages of restoration are very useful for predicting outcomes. We posed following questions: Can savanna outcomes be affected by initial functional‐group composition? Are there functional groups that, when established early, prevent colonization invasive grasses, trigger a successful trajectory, and used as indicators success? Location Brazilian (cerrado) in Central Brazil (14°07′2.54″ S, 47°38′30.36″ W). Methods 110...
Defining the reference system for restoration projects in regions characterized by complex vegetation mosaics is challenging. Here we use Cerrado region of Brazil as an example importance clearly defining multiple natural and anthropogenically altered states grassland‐savanna‐forest mosaics. We define three main, types–grassland, savanna, scleromorphic ( cerradão ) forest–to (1) distinguish between original degraded (2) set appropriate targets guide restoration. contend that differences...

Here we show how community-based organizations have co-developed strategies landscape restoration from bottom-up. We draw on interconnections over two decades networks Brazil emerging...
