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

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

Published: May 27, 2021

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.

Assessing Ecological Restoration in Arid Mining Regions: A Progressive Evaluation System

Sustainability, Journal Year: 2024, Volume and Issue: 16(6), P. 2266 - 2266

Published: March 8, 2024

The mining activities in arid regions have resulted significant ecological environmental issues, exacerbating the already challenging conditions and leading to severe ecosystem damage. Merely relying on natural recovery processes proves inadequate, thus necessitating implementation of artificial restoration measures facilitate these regions. However, it is difficult scientifically answer questions how can be effectively combined with recovery, what extent assistance define beginning ecosystems. To address this issue, study proposed a stepwise model for delineated process into three phases: “artificial reconstruction”, “auxiliary restoration”, “natural recovery”, constructed an evaluation index system process. Taking example Aksu, Xinjiang, examined effects projects research showed that adopting achieve scientific moderate restoration, better clarify goals, projects.

Soil salinization poses an important threat to terrestrial ecosystems and is expected increase as a consequence of climate change anthropogenic pressures. Conventional methods such salt-leaching or application soil amendments, nature-based solutions (NBSs) phytoremediation, have been widely adopted with contrasting results. The use cyanobacteria for improving conditions has emerged novel biotechnological tool ecosystem restoration due the unique features these organisms, e.g., ability fix carbon nitrogen promote stabilisation. Cyanobacteria distribute over wide range salt concentrations several species can adapt fluctuating salinity conditions. Their in agricultural saline remediation demonstrated, mostly laboratory studies, but there lack research regarding their natural restoration. In this article, we provide overview current knowledge on context Examples alleviating salt-stress plants soils are presented.

Transplanted sagebrush “wildlings” exhibit higher survival than greenhouse-grown tubelings yet both recruit new plants

BMC Ecology and Evolution, Journal Year: 2024, Volume and Issue: 24(1)

Published: April 22, 2024

Abstract Background Land uses such as crop production, livestock grazing, mining, and urban development have contributed to degradation of drylands worldwide. Loss big sagebrush ( Artemisia tridentata ) on disturbed across the western U.S. has prompted massive efforts re-establish this foundational species. There been growing interest in avoiding severe limitations experienced by plants at seed seedling stages instead establishing from containerized greenhouse seedlings (“tubelings”). In some settings, a potential alternative approach is transplant larger locally-collected (“wildlings”). We compared establishment mountain A. ssp. vaseyana tubelings vs. wildlings southeastern Idaho. A mix native non-native grass forb species was drill-seeded pasture previously dominated introduced forage grass, smooth brome Bromus inermis ). then established 80 m x treatment plots planted n = 12 plots, 1200 plants) plants). also seeded 12) untreated control 6) for long-term comparison. tracked project expenses order calculate costs using modified probability success. Results high (79%) tubeling low (10%) wildling mortality within first year. Three years post-planting, chance survival significantly higher than that (85% 14% respectively). Despite up-front planting wildlings, rates resulted their being < 50% cost per-surviving plant basis. Additionally, third year post-planting 34% surviving 95% showed evidence reproduction (presence / absence flowering stems), two types plantings recruited new via (3.7 2.4 plants, respectively, per tubeling/wildling). Conclusions Our results indicate with more developed root systems (wildlings) may be promising avenue increasing early restoration settings. illustrate improve outcomes “nucleating” landscape recruitment during ideal climate conditions.
