Challenges to the Reforestation Pipeline in the United States

Frontiers in Forests and Global Change, Год журнала: 2021, Номер 4

Опубликована: Фев. 4, 2021

Large-scale global reforestation goals have been proposed to help mitigate climate change and provide other ecosystem services. To explore potential in the United States, we used GIS analyses, surveys of nursery managers foresters, literature synthesis assess opportunities challenges associated with meeting goals. We considered a scenario where 26 million hectares (64 acres) natural agricultural lands are reforested by 2040 30 billion trees at an estimated cost $33 ($24–$53) USD. Cost per hectare will vary region, site conditions, factors. This would require increasing number tree seedlings produced each year 1.7 billion, 2.3-fold increase over current production levels. Additional investment (not included estimate) be needed expand capacity for seed collection, seedling production, workforce development, improvements pre- post-planting practices. Achieving this public support investing these activities incentives landowners.

Restoring forests: regeneration and ecosystem function for the future

Conventions and policies for biodiversity conservation climate change mitigation state the need increased protection, restoration adaptation of forests. Much degraded land may be targeted large-scale forest restoration, yet challenges include costs, a shortage regeneration material restored forests to serve as resource communities. To ensure ecosystem function future, programs must: (1) learn from past; (2) integrate ecological knowledge; (3) advance techniques systems; (4) overcome biotic abiotic disturbances (5) adapt future landscapes. Historical conditions, while site-specific, help identify processes that leave long-term legacies in current understand tree migration biology/population dynamics their relationship with change. Ecological theory around plant–plant interactions has shown importance negative (competition) positive (facilitation) which will become more relevant increasing drought due Selective animal browsing influences efforts establish species-rich forests; an integrated approach is needed simultaneously manage ungulate populations, landscape carrying capacity browse-tolerant regeneration.

Forest Landscape Restoration—What Generates Failure and Success?

Forests, Год журнала: 2020, Номер 11(9), С. 938 - 938

Research Highlights: The global Forest Landscape Restoration ambitions could be impaired by projects that ignore key principles such as the engagement of local communities in decision making and implementation, equitable benefit sharing, monitoring for adaptive management. This entails danger continued degradation, disappointed stakeholders, ultimately, project failure. Other face technical problems related to tree establishment nursery production. Background Objectives: There are high hopes regain ecosystem integrity enhance human well-being deforested degraded areas. We highlight various success factors experienced during implementation on a scale. Materials Methods: use data from online survey identify common obstacles forest restoration. Results: While majority respondents reported successful projects, others indicate drastic failed projects. Major restoration were lack stakeholder involvement mismatch between goals managers, well environmental, anthropogenic, barriers regeneration. Conclusions: When communities, their goals, needs disregarded planning cases our limited available literature, there is risk Failed discouraged funders policy-makers, lessen momentum ambitions. Adhering can promote much-needed community support, with potential overcome regeneration enable protection, management, restored forests beyond funding periods. needed gain better understanding perception towards activities. Further studies at intersection environmental factors, socioeconomic conditions, regeneration/silviculture, production needed.

Forest landscape restoration: state of play

Tree planting has been widely touted as an inexpensive way to meet multiple international environmental goals for mitigating climate change, reversing landscape degradation and restoring biodiversity restoration. The Bonn Challenge New York Declaration on Forests, motivated by widespread deforestation forest degradation, call 350 million ha 2030 relying restoration (FLR) processes. Because the 173 commitments made 63 nations, regions companies are not legally binding, expectations of what FLR means lacks consensus. frequent disconnect between top-level aspirations on-the-ground implementation results in limited data activities. Additionally, some countries have landscape-scale outside Challenge.

Major bottlenecks for the restoration of natural forests in Chile

Restoration Ecology, Год журнала: 2018, Номер 26(6), С. 1039 - 1044

Опубликована: Авг. 25, 2018

International agreements combined with the recent Chilean Forestry Policy (2015–2035) represent a challenge and an opportunity for forest landscape restoration in Chile. Nevertheless, restoring over 500,000 ha using mainly native species seems like daunting task by 2035. Here, we discuss three major bottlenecks that currently constrain efforts of ecosystems First, Chile urgently needs national strategic plan restoration, which should take into account mid‐ long‐term goals. There is also need to prioritize resource allocation efficient use, promoting creation economic subsidies consider different types ecosystems. Second, there great better nursery protocols plant production as well strengthen educational programs professional technical training, given lack high‐quality personnel nurseries. This would help increase limited supply, improving quality increasing diversity suitable restoration. Lastly, taking advantage novel eco‐technological tools innovative plantation design overcome usually deficient results establishment phase, leading higher survival rates performance species. Beyond current experiments are relatively on small spatial scale, practice become massive successful at scale. More applied research crucial impact so can achieve its next decade.

Plant quality and survival prediction tools are useful when applied in the field different agricultural sectors. The objectives of this study were to conduct a review bibliometric analysis Dickson Quality Index (DQI) as key plant indicator with respect its scientific applications. A third objective was identify main morphological physiological parameters used production research. methodology findings 289 articles analysed based on morphological, physiological, mathematical indicators research forest, medicinal, horticultural, aromatic, ornamental species. During last 10 years, number publications that have DQI parameter has increased by 150%, Brazilian researchers stand out most frequent users. Forestry is discipline where their biometric relationships often facilitate intensive production. Use increases certainty prediction, selection, productivity chain. robust tool application great potential for use preselection plants high standards among wide range
