“…This means that even when invasive species are removed, their effects on the ecosystem persist, which has important practical implications for ecosystem restoration and management [ 47 ]. Second, nitrogen deposition is essential in regulating plant invasions’ legacy effects [ 48 ]. Nitrogen deposition can alter soil nitrogen availability, affecting plant invasions’ legacy effects, suggesting that global nitrogen deposition may further exacerbate the legacy effects of invasive species.…”

The legacy effects of invasive plant species can hinder the recovery of native communities, especially under nitrogen deposition conditions, where invasive species show growth advantages and trigger secondary invasions in controlled areas. Therefore, it is crucial to thoroughly investigate the effects of nitrogen deposition on the legacy effects of plant invasions and their mechanisms. The hypotheses of this study are as follows: (1) Nitrogen deposition amplifies the legacy effects of plant invasion. This phenomenon was investigated by analysing four potential mechanisms covering community system structure, nitrogen metabolism, geochemical cycles, and microbial mechanisms. The results suggest that microorganisms drive plant–soil feedback processes, even regulating or limiting other factors. (2) The impact of nitrogen deposition on the legacy effects of plant invasions may be intensified primarily through enhanced nitrogen metabolism via microbial anaerobes bacteria. Essential insights into invasion ecology and ecological management have been provided by analysing how nitrogen-fixing bacteria improve nitrogen metabolism and establish sustainable methods for controlling invasive plant species. This in-depth study contributes to our better understanding of the lasting effects of plant invasions on ecosystems and provides valuable guidance for future ecological management.

While the impacts of invasive plants are commonly researched and described within the context of agriculture and restoration ecology, they receive less attention within the specific context of forestry. Forestry operations are both vulnerable to and could exacerbate the spread of invasive plants through all aspects of silviculture, all of which can lead to reduced profitability and negative impacts to the sustainability and resiliency of the ecosystems they operate within. The purpose of this review article was to synthesize the current academic and gray literature pertaining to invasive plants and forestry to inform prevention and management approaches and identify gaps in the research. We incorporated a case study from interviews with major forestry company professionals in British Columbia, Canada managing invasive species within their operations to provide critical and often overlooked perspectives and experiences. Our review provides key insights into the risks invasive plants pose to forest community and tree health, operations, economic value, and ecosystem health and identifies the need for research specific to the impacts of invasive plants and their management strategies within the context of forestry operations.

Plants can produce and release allelochemicals to interfere with the establishment and growth of conspecific and interspecific plants. Such allelopathy is an important mediator among plant species in natural and managed ecosystems. This review focuses on allelopathy and allelochemicals in grasslands and forests. Allelopathy drives plant invasion, exacerbates grassland degradation and contributes to natural forest regeneration. Furthermore, autotoxicity (intraspecific allelopathy) frequently occurs in pastures and tree plantations. Various specialized metabolites, including phenolics, terpenoids and nitrogen-containing compounds from herbaceous and woody species are responsible for allelopathy in grasslands and forests. Terpenoids with a diversity of metabolites are qualitative allelochemicals occurring in annual grasslands, while phenolics with a few specialized metabolites are quantitative allelochemicals occurring in perennial forests. Importantly, allelochemicals mediate below-ground ecological interactions and plant–soil feedback, subsequently affecting the biodiversity, productivity and sustainability of grasslands and forests. Interestingly, allelopathic plants can discriminate the identity of neighbors via signaling chemicals, adjusting the production of allelochemicals. Therefore, allelochemicals and signaling chemicals synergistically interact to regulate interspecific and intraspecific interactions in grasslands and forests. Allelopathy and allelochemicals in grasslands and forests have provided fascinating insights into plant–plant interactions and their consequences for biodiversity, productivity and sustainability, contributing to our understanding of terrestrial ecosystems and global changes.
