The urban environment is a source and carrier of heavy metals due to industrial waste. establishment industries the emission contaminants are not real problems; big issue mixing in healthy environment. There an urgent need adopt best approach restricting at introductory level discharge keeping apart from As consequence, phytostabilization rhizofiltration most specifically used successful plant-based methods for eliminating toxins polluted regions with low impact on water bodies or soil structure. It also has advantages producing secondary waste that must be treated stabilizing qualities as compared other conventional treating methods. comprehensive study helps us establish suitable selection technique particular metal-bearing effluent based time consumption efficiency, well identify plants typically employed rhizofiltration. This paper aims compile important information about relation stabilization. described phytoremedial action plan, remedy decision tree, soil/sediment tree.

Direct Seeding in Reforestation – A Field Performance Review

REFORESTA, Journal Year: 2017, Volume and Issue: 4, P. 94 - 142

Published: Dec. 30, 2017

Direct seeding has been considered a forest restoration option for centuries. Over the past half century, use of this practice declined in developed countries as regeneration programs have advanced with production quality seedlings that can successfully establish sites. is being reconsidered potential size worldwide program grown because massive deforestation third-world nations and due to global climate change. This review examines direct from number perspectives. First, merits using are defined. Major it be done quickly, over hard reach large disturbed areas, at relatively low cost. Second, current research findings discussed. The major finding seedling establishment rates (i.e. typically around 20% seeds planted) site conditions, seed predation vegetation competition, field performance survival growth) lower than planted seedlings. Third, operational practices application reviewed. To conduct practitioners need consider seedbed receptivity, distribution rate. Fourth, new presented. Some these attempt create more effective means disperse across site, minimize or favorable microsite environment. provides synthesis what known about seeding, thereby allowing make rational decision whether apply towards their program.

Developing and supporting quality nursery facilities and staff are necessary to meet global forest and landscape restoration needs

REFORESTA, Journal Year: 2017, Volume and Issue: 4, P. 69 - 93

Published: Dec. 30, 2017

Seedlings are the foundation for many terrestrial ecosystems and a critical consideration investment implementing global forest landscape restoration programs. Global leaders have pledged to restore millions of hectares during next decade, necessitating established plants. Although natural regeneration direct seeding will likely meet portion that need, large quantities high-quality, nursery-grown seedlings also required. Insufficient plant or poor-quality plants result in unsuccessful outplanting Such failures considerable economic environmental consequences an inability goals. Nonetheless, importance nurseries is often overlooked when making large-scale commitments. Technology already exists produce high-quality variety This technology cannot be applied, however, unless adequate resources training made available by overcoming political socioeconomic barriers. In this article, we discuss important role commitments review three case studies where increased support nursery programs resulted improved success.

Precision restoration: a necessary approach to foster forest recovery in the 21st century

Restoration Ecology, Journal Year: 2021, Volume and Issue: 29(7)

Forest restoration is currently a primary objective in environmental management policies at global scale, to the extent that impressive initiatives and commitments have been launched plant billions of trees. However, resources are limited success any effort should be maximized. Thus, programs seek guarantee what planted today will become an adult tree future, simple fact that, however, usually receives little attention. Here, we advocate for need focus efforts on individual level increase establishment while reducing negative side effects by using approach term “precision forest restoration” (PFR). The PFR ensure seedlings or sowed seeds trees with appropriate landscape configuration create functional self‐regulating ecosystems impacts traditional massive reforestation actions. can take advantage ecological knowledge together technologies methodologies from scale individual‐plant more traditional, low‐tech approaches latest high‐tech ones. may expensive plants, but cost‐effective long if it allows creation resilient forests able provide multiple ecosystem services. was not feasible few years ago due high cost low precision available technologies, alternative might reformulate wide spectrum activities.

Need to Seed? Ecological, Genetic, and Evolutionary Keys to Seed-Based Wetland Restoration

Frontiers in Environmental Science, Journal Year: 2020, Volume and Issue: 8

Published: Aug. 18, 2020

As we approach the Decade of Ecosystem Restoration (2021–2030), there is renewed focus on improving wetland restoration practices to reestablish habitat and climate mitigation functions services that wetlands provide. A first step in restoring these native vegetation structure composition through strategic seed-based approaches. These approaches should be driven by ecological, genetic, evolutionary principles, along with consideration for economics, logistics, other social constraints. Effective must consider chosen species, seed sourcing, dormancy break germination requirements, enhancement technologies, potential invaders, seeding densities, long-term monitoring. Choice species reflect historical plant communities future environmental conditions, support functional goals including invasion resistance, availability Furthermore, seeds sourced ensure ample genetic diversity multifunctionality capacity while also considering broad natural dispersal many species. The decision collect wild or purchase will impact choice diversity, which can have cascading effects goals. To seedling establishment, addressed breaking treatments potentially narrow requirements some require targeted sowing timing location align safe sites. Other enhancements such as priming coatings are poorly developed their establishment unknown. Because highly prone, invaders legacies addressed. Seeding densities strike a balance between outcompeting preserving valuable resources. Invader control monitoring key revegetation restoration. Here, review scientific advances improve outcomes, provide methods recommendations help achieve desired Gaps knowledge about currently exist, however, untested certainly increase risks efforts. efforts used better understand processes related seeds, bring us one closer needed human ecological communities.
