Social Impact Statement Botanic gardens and arboreta have evolved significantly from their origins as oases reserved for the elite, to conservation powerhouses they are today, visited by over half a billion people annually. Now, with sophisticated facilities botanical expertise, uniquely positioned address many of challenges associated preserving plant diversity benefit planet. Globally, however, resources awareness these efforts limited. Funders, governments, corporations, global citizens...
The multiple, complex risks to plant species survival are increasing, and conservation strategies that include ex situ as well in approaches needed now more than ever. Seed banking (drying at c.15% relative humidity then storing −20 °C) is the most efficient effective method for long-term a majority of species. However, some not amenable this practice, such have been labeled exceptional. Critical limitations conventional seed include: 1) unavailability sufficient storage; 2) seeds completely...
Maintaining a living plant collection is the most common method of ex situ conservation for species that cannot be seed banked (i.e., exceptional species). Viability collections, and their value future efforts, can limited without coordinated efforts to track manage individuals across institutions. Using pedigree-focused approach, zoological community has established an inter-institutional infrastructure support long-term viability captive animal populations. We assessed ability this...
Species loss due to human activities is occurring at an unprecedented pace (Barnosky et al., 2011), and over the last few decades, botanic gardens have responded by expanding their conservation (CBD, 2010). Botanic play a particularly critical role in development of ex situ (off-site) collections threatened plant species, garden community has helped develop current best practices for reintroduction (e.g., via Center Plant Conservation; Guerrant 2004). The majority species are amenable seed...
Effectively conserving biodiversity with limited resources requires scientifically informed and efficient strategies. Guidance is particularly needed on how many living plants are necessary to conserve a threshold level of genetic diversity in ex situ collections. We investigated this question for 11 taxa across five genera. In first study analysing optimizing multiple genera, we found that the percentage extant currently conserved varies among from 40% 95%. Most well below conservation...
Quantitative assessments of endemism, evolutionary distinctiveness and extinction threat underpin global conservation prioritization for well-studied taxa, such as birds, mammals, amphibians. However, information is unavailable most the world's taxa. This case Orchidaceae, a hyperdiverse cosmopolitan family with incomplete phylogenetic information. To define priorities, we present framework based on taxonomic measures rarity number regions area occupancy. For 25,434 orchid species...
With two in five plant species facing extinction, diversity loss demands action that integrates ex situ with conservation approaches. While seed banks has been widely adopted, this technology cannot be applied to exceptional species, which require alternative We propose a new conceptual framework, resulting the creation of global working Exceptional Status List. Using semi-automated method evaluate over 23,000 plants, 775 were identified as exceptional, <3% those predicted exceptional. These...
Conservation of imperiled plant species often requires ex situ (offsite) living collections. Protocols for developing these collections most emphasize sampling depth, but little is known about the genetics such This study compares how well a single collecting protocol can capture diversity in wild populations two closely related species. We selected exemplar species, bay rush (Zamia lucayana) and sinkhole cycad decumbens), based on similarities differences that allow rigorous comparison,...
Premise of research. To safeguard threatened plant species, best-practice guidelines and genetic modeling emphasize that ex situ collections should be composed high numbers maternal lines. Threatened species often present challenges to meeting this standard due biology or logistics. An approach pools garden into a single larger metacollection may more effective at capturing diversity. This study examines the capture compares with an idealized model for sampling.Methodology. The Pseudophoenix...
Premise of research. Ex situ plant conservation can be improved through genetic analysis. One area interest is the relative value conserving smaller or larger populations and how sampling strategies for these might differ. Current practice emphasizes collecting large sample sizes from some limiting others aims capture allele diversity exceeding predetermined thresholds at species level. Evaluating well botanic garden collections different help refine guidance on efforts.Methodology. A model...
The 2020 State of the World's Plants and Fungi report revealed that two in five plant species are threatened with extinction. Despite their diverse ecosystem services myriad human uses, plants receive a fraction conservation resources directed at animal taxa. Several existing frameworks-including International Union for Conservation Nature (IUCN) Specialist Groups, American Public Gardens Association Plant Collections Network, Center National Collection Endangered Plants-have spurred action,...
Societal Impact Statement Understanding the current state of trees within United States is imperative for protecting those species, their habitats, and countless communities they support, as well ecosystem services provide. We present an updated checklist all tree species native to contiguous States, distribution, extinction risk, most common threats. Knowledge national threat “hotspots” conservation priorities facilitates efficient efforts allocation resources safeguard 11–16% US that are...
ABSTRACT Humans rely on crop wild relatives (CWRs) for sustainable agriculture and food security through augmentation of yield, disease resistance, climatic tolerance, among other important traits. Many CWRs are underrepresented in gene banks. With at least one‐third known plant species maintained botanic garden living collections, the community serves as an global ex situ network that supports conservation research around world. We sought to characterize holdings demonstrate capacity...
Under the old taxon Principes, palms were once Princes of Kingdom Plantae. First on Engler’s list, they occupy a cherished place to botanists, and remain treasured centerpieces many gardens. In turn, botanic gardens have put forward decades-long effort conserve these widely admired plants, keeping number palm species from extinction. Living collections also critical value for comparative ecological studies. this paper we highlight successful ex situ conservation programs palms, review how...
Botanic garden collections are increasingly seeking to quantify and improve the value of their for science, horticulture, conservation other uses. Quantifying a collection depends on mission institution. Many botanic gardens prioritising rare threatened species towards preventing plant extinctions. In doing so, must make decisions about which plants should remain, be replaced or added collections, how allocate staff resources care individual plants, while considering funding space limits....
