Recent estimates indicate that one-fifth of botanical species worldwide are considered at risk becoming extinct in the wild. One available strategy for conserving many rare plant is reintroduction, which holds much promise especially when carefully planned by following guidelines and monitored long-term. We review Center Plant Conservation Best Reintroduction Practice Guidelines highlight important components planning reintroductions. Before attempting reintroductions practitioners should...
The fundamental goal of a rare plant translocation is to create self-sustaining populations with the evolutionary resilience persist in long term. Yet, most syntheses focus on few factors influencing short-term benchmarks success (e.g., survival and reproduction). Short-term can be misleading when trying infer future growth viability because that promote establishment may differ from those required for long-term persistence. We assembled large (n = 275) broadly representative data set...
Abstract Many countries have legislation intended to limit or offset the impact of anthropogenic disturbance and development on threatened plants. Translocations are often integral those mitigation policies. When translocation is used exclusively mitigate impacts, it termed a ‘mitigation translocation.’ However, both terminology processes vary regarding interpretation application, resulting in inconsistent standards, leading poorly planned implemented projects. These projects rarely achieve...
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...
Reintroductions are important components of conservation and recovery programs for rare plant species, but their long-term success rates poorly understood. Previous reviews reintroductions focused on short-term (e.g., ≤3 years) survival flowering founder individuals rather than benchmarks intergenerational persistence, such as seedling recruitment. However, metrics may obscure outcomes because the unique demographic properties reintroductions, including small size unstable stage structure,...
Summary 1. In deciduous forests, herb distribution patterns can shift dramatically across topographical gradients, yet it remains unclear whether associations reflect regeneration niche differences that arise during early life‐history stages. 2. We examined: (i) seedling recruitment were consistent with distributions of established populations and (ii) how environmental heterogeneity at two spatial scales influences in four shade‐adapted forest herbs ( Actaea racemosa , Hydrastis canadensis...
Despite its successes, the U.S. Endangered Species Act (ESA) has proven challenging to implement due funding limitations, workload backlog, and other problems. As threats species survival intensify as more come under threat, need for ESA similar conservation laws policies in countries function efficiently grown. Attempts by Fish Wildlife Service (USFWS) streamline decisions include multispecies recovery plans habitat plans. We address status assessment (SSA), a USFWS process inform from...
Reintroductions or translocations are an increasingly important activity to recover and conserve at-risk plant species. Yet because many not published in the scientific literature, learning from previous attempts may often require considerable time effort. The Center for Plant Conservation Reintroduction Database (CPCRD; https://saveplants.org/reintroduction-database/), a new centralized standardized repository of U.S.-based reintroductions, aims improve efficiency effectiveness accessing...
The creation of new populations in conservation reserves plays an increasingly important role reducing the extinction risk endangered plants. We experimentally introduced seedlings federally forb Astragalus bibullatus into protected limestone cedar glades central Tennessee and tested how source population, transplant season, glade site affected demographic performance transplants over 7 years. Plants derived from seed three survived at similar rates sites, but exhibited different germination...
Reintroductions of rare plants require detailed knowledge habitat requirements, species interactions, and restoration techniques. Thus, incremental experimentation over many years may be required to develop adequate techniques for successful reintroduction. To determine drivers extinction in historical reintroductions a federally endangered perennial (Astragalus bibullatus), we developed reintroduction experiment disentangle the relative importance quality, herbivores, technique on success....
Abstract Seed limitation represents a fundamental constraint to the restoration of native plant communities, and practitioners often apply seed additions overcome this barrier. However, surprisingly few studies have experimentally tested whether can increase diversity in herbaceous communities oak woodlands, which undergone large‐scale transformation due logging, altered fire regimes invasion by non‐native species. Previous suggest that structural (thinning woody biomass) process‐based...
Understanding genetic diversity and structure in a rare species is critical for prioritizing both situ ex conservation efforts. One such Physaria filiformis (Brassicaceae), threatened, winter annual plant species. The has naturally fragmented distribution, occupying three different soil types spread across four disjunct geographical locations Missouri Arkansas. goals of this study were to understand: (1) whether factors associated with fragmentation small population size (i.e., inbreeding,...
Goldenseal is an uncommon woodland herb whose rhizomes are widely harvested for their medicinal properties. populations regenerate from vegetative propagules that broken-off the primary rhizome during harvesting activities. While previous studies reported significant variability in re-growth among populations, it not entirely clear what drives differences population re-growth. One hypothesis goldenseal re-grow at greater rates when fall compared to mid-summer. Over a 4 y period, we...
The success of rare plant conservation programs depends upon understanding the ecological factors that regulate seed dormancy and germination. In this study, we characterize germination niche with respect to temperature light three imperiled perennials are endemic rock outcrops in southeastern United States: Astragalus bibullatus, Claytonia ozarkensis, Conradina verticillata. Our results show a majority seeds for each species unable germinate at habitat temperatures prevailing after...
