The relative influence of geographic and environmental factors on rare plant translocation outcomes

Journal of Applied Ecology, Journal Year: 2025, Volume and Issue: unknown

Published: Jan. 22, 2025

Abstract Conservation translocations are an established method for reducing the extinction risk of plant species through intentional movement within or outside indigenous range. Unsuitable environmental conditions at translocation recipient sites and a lack understanding species–environment relationships often identified as critical barriers to success. However, previous syntheses have drawn these inferences from analyses qualitative feedback rather than quantitative data. In this study, we use data set 235 conducted in US understand influences geographic factors on three metrics success: population persistence, next‐generation recruitment maturity. We random forest models quantify relative importance that characterize dissimilarity between source locations, position species' ranges niche derived ranges. also compare variables with more conventional predictors (e.g. founder size). Our results indicate can be insightful predicting outcomes. The climate suitability sites, estimated using distribution models, was strongest predictor whether persisted, populations situated suitable climates displaying greater persistence. Next‐generation maturity were best predicted by metrics; biotically limiting environments, including tropical regions soils high nutrient retention, well broadest precipitation niches, least likely attain benchmarks. Synthesis applications . study is one first important role spatial climatic rare provide novel perspective outcomes demonstrate opportunities improve success not only adhering practice guidelines but integrating modelling approaches into planning management processes.

Abstract Conservation translocations are a well‐known conservation tool used to reverse the effects of local population extinctions and restore ecosystems. Compared with mammals birds, plants underrepresented in translocation programs, little is known about potential taxonomic phylogenetic biases plant efforts. We aimed assess how translocated species may contribute diversity (PD) among European countries. Focusing on angiosperms across 4 countries well‐documented flora comprehensive sampling species, we determined whether were related status binomial generalized linear mixed models threat as binary response variable. Then, evaluated relative national floras based PD evolutionary distinctiveness (ED). To evaluate ED, constructed null deviation observed values from those expected under scenario which randomly sampled pool each country. Although most lacked assessment, mainly targeted high extinction risk at national, European, global scales. orders higher representativeness also tended have native probability being varied significantly order, suggesting significant bias. Based considering all countries, mean ED than by chance These results suggest that although programs implemented independently relevant conserving continental scales restoring evolutionarily distinct when these succeed. argue indicators should be incorporated into planning target species’ trajectories PD.

This study aimed to identify the key environmental factors influencing survival and growth of endangered plant Lychnis kiusiana Makino through translocation experiments across different sites (sites A, B, C; A = shady, B partial C sunny). The analysis revealed strong correlations between with such as soil moisture, electroconductivity, coverage, light. Utilizing a multimodel inference approach, which accounts for complex interactions among variables, found that coverage electroconductivity were most significant predictors survival, while moisture was primary factor affecting growth. Coverage played crucial role in early by regulating microclimate, providing shading effects, aiding retention.

Athrotaxis cupressoides is an endemic conifer restricted to montane areas of Tasmania. It slow‐growing and vulnerable the increasing wildfire activity associated with climate change. We explored novel idea that disused gravel pits could serve as artificial fire refugia for transplanted populations. compared survival, growth, response fertilizer nursery‐grown A. transplants in these refugia, which had mineral soils, burnt unburnt sites wilderness areas, organic soils. Survival over 16‐month trial increased initial transplant height was slightly higher (97%) than (89%). Height growth unfertilized plants slow, especially pits. However, boosted most strongly pits, rates similar those fertilized sites. Our results show it feasible reintroduce into populations eliminated by wildfire. They also demonstrate capacity reclaim creating new localized this iconic species. Thus, denuded can be re‐imagined help maintain other long‐lived but fire‐sensitive wild.

Abstract The Endangered Species Act aims to recover imperiled species the point of delisting; however, few plant have been delisted due recovery. Critical many species' recovery criteria are introductions, yet long‐term success introductions is highly variable and their use in delisting decisions relatively untested. In this study, we examined dynamics eight introduced populations recently Chrysopsis floridana (Florida Golden Aster), a fire‐dependent perennial endemic Florida scrub habitats. We analyzed 6 years demographic data (2017–2022) 10 prescribed fire records assess population trends, management effects, vital rates related recruitment, survival, reproduction. Our results show that densities with regular increased, while unburned generally declined. Prescribed increased seedling recruitment survival rates. estimated fire‐return interval approximately 5 needed for persistence, shorter than 10‐year used decision. findings suggest post‐delisting monitoring should prioritize ensure populations. work highlights need more robust, specific criteria, particularly regarding role monitoring, post‐introduction habitat management. These insights can inform future plans improve process plants under Act.

Balancing Risk and Resilience: Which Plant Traits Should Inform Managed Relocation Species Selection?

Global Change Biology, Journal Year: 2025, Volume and Issue: 31(3)

Published: March 1, 2025

Managed relocation is a critical tool for promoting ecological resilience in the face of climate change, and approach has been proposed restoration plant communities. Given that species poses some risk to recipient ecosystem, traits associated with invasiveness have as means assessing selecting candidate managed relocation. However, could also be relevant successful (and, turn, relocation)-particularly those linked establishment viable populations. Here, we review studies invasion ecology paired functional, ecological, biogeographic stages or ask which should used inform selection. We find substantial overlap between during population establishment, but divergence spread impacts, suggesting selection only focus on promote long-distance impact. Instead, few existing protocols utilize establishment. unintended harm from orders magnitude smaller than non-native introduction, focusing assessments likely exclude most able establish populations, causing failure rates recommend candidates invasive impacts are not necessary restoration. threats posed by balanced assessment does severely limit will best support adaptation strategy.
