Horticulture could facilitate invasive plant range infilling and range expansion with climate change

BioScience, Journal Year: 2023, Volume and Issue: 73(9), P. 635 - 642

Published: Sept. 1, 2023

Abstract Invasive plants are often sold as ornamental garden plants, but how species in the same locations where they invasive? To answer this question, we assessed geography of plant sales United States relation to existing invasions and potential invasion risk with climate change. Using a data set 672 nurseries selling 89 invasive estimated distance between nursery species’ observed distributions. We also used range maps identify within current invaded ranges, well future ranges given Half were by 21 kilometers an record invasion. Under climate, horticulture could be seeding for 73 studied, facilitate climate-driven expansion 25 species. Our results illustrate risks associated horticultural introductions species, providing guidance regulatory educational interventions that reduce spread ongoing invasions.

A Quantitative Classification of the Geography of Non‐Native Flora in the United States

Global Ecology and Biogeography, Journal Year: 2025, Volume and Issue: 34(4)

Published: April 1, 2025

ABSTRACT Aim Non‐native plants have the potential to harm ecosystems. Harm is classically related their distribution and abundance, but this geographical information often unknown. Here, we assess commonness as a indicator of invasive status for non‐native flora in United States. Geographical could inform invasion risk assessments across species ecoregions. Location Conterminous Time Period Through 2022. Major Taxa Studied Plants. Methods We compiled standardised occurrence abundance data from 14 spatial datasets used categorise uncommon or common based on three dimensions commonness: area occupancy, habitat breadth local abundance. To consistency existing categorizations, compared identified with higher‐than‐expected relative residence time. calculated plant richness within States ecoregions estimated unreported rarefaction/extrapolation curves. Results This comprehensive database 1874 recorded 4,844,963 locations. Of these, 1221 were locally abundant (> 10% cover) 797,759 unique One thousand one hundred (59%) achieved at least dimension commonness, including 565 that all three.

Shifting hotspots: Climate change projected to drive contractions and expansions of invasive plant abundance habitats

Quantifying vulnerability to plant invasion across global ecosystems

Abstract The widely-referenced “tens rule” in invasion ecology suggests that 10% of established, non-native species will become invasive. However, the accuracy this estimate has been questioned, as original analysis focused on small groups plant Great Britain and Australia. Using a novel database 9,501 established 2,924 invasive plants, we provide comprehensive evaluation rates first empirical how tens rule varies across climate zones spatial scales. We found ranged from 17% at country scale to 25% continental scale. Tropical communities are often considered be resistant invasion, however our results showed significantly higher tropics especially tropical islands, suggesting unexpectedly high vulnerability these species-rich ecosystems. Our provides improved, environment-specific estimates which twice previous expectations. recommend practitioners reject for plants adjust future management practices reflect updated risk.

Breaking down barriers to consistent, climate‐smart regulation of invasive plants: A case study of US Northeast states

Ecosphere, Journal Year: 2022, Volume and Issue: 13(5)

Abstract Efforts to prevent the introduction and spread of new invasive plants are most effective when regulated species consistent across jurisdictional boundaries proactively prohibit before they arrive or in earliest stages invasion. Consistent proactive regulation is particularly important northeastern United States, which susceptible many due climate change. Unfortunately, recent analyses state plant lists show that neither nor proactive. To understand why, we focus on two steps leading six states (Connecticut, Maine, Massachusetts, New Hampshire, York, Vermont): sets evaluated how risk assessed. Our analysis confirms previous findings regulations inconsistent reactive. Of 128 by one more states, 54 were a single only 16 all states; tended be widespread region (not proactive). These outcomes largely driven different species. For example, neighboring Vermont Hampshire 92 total, but 26 overlapped. In addition, rarely absent from state. Risk assessment protocols varied considerably consistently included criteria related ecological impact, potential establish, dispersal mechanisms, life history traits. While none assessments explicitly consider change, also did not contain language would preclude regulating have yet arrived increase consistency proactivity, benefit (1) evaluating identified as high high‐risk, range‐shifting species, both compiled here, (2) considering change assessing “potential distribution” impact” target Additionally, mechanism for sharing knowledge regionally with fewer resources address threats.

Translational invasion ecology: bridging research and practice to address one of the greatest threats to biodiversity

Biological Invasions, Journal Year: 2021, Volume and Issue: 23(11), P. 3323 - 3335

Published: July 4, 2021

Abstract Effective natural resource management and policy is contingent on information generated by research. Conversely, the applicability of research depends whether it responsive to needs constraints managers makers. However, many scientific fields including invasion ecology suffer from a disconnect between practice. Despite strong socio-political imperatives, evidenced extensive funding dedicated addressing invasive species, pairing with stakeholder support effective lacking. As potential solution, we propose translational (TIE). an extension ecology, as framework increase collaboration among scientists, practitioners, makers reduce negative impacts species. TIE approach that embodies intentional inclusive process in which researchers, stakeholders, decision collaborate develop implement ecological via joint consideration ecological, sociological, economic, and/or political contexts order improve species management. ideally results improved outcomes well shared benefits researchers managers. We delineate steps our proposed describe successful examples ongoing projects US internationally. suggest practical ways begin incorporating into practices, supporting boundary-spanning organizations activities, expanding networks, sharing experiences, measuring outcomes. find there need for strengthened boundary spanning, recognition advancing approaches. climate change globalization exacerbate impacts, provides promising generate actionable while improving decisions.

Abstract With increasing impacts of climate change observed across ecosystems, there is an urgent need to consider in all future environmental policy. But existing policy and management might be slow respond this challenge, leading missed opportunities incorporate into practice. Furthermore, invasive species threats continue rise interact with change—exacerbating negative impacts. Enabling natural resource managers individuals proactive about climate-driven creates a win–win for conservation. Recommendations include expanding information sharing borders, supporting screening regulation high-risk on the horizon, incentivizing individual actions that reduce ecological In addition, risk should considered when crafting mitigation adaptation compounding stressors ecosystems. As we develop much-needed tools harm, must combined invasions change.
