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...
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,...
The global biodiversity crisis affects species across all continents and taxonomic groups. Direct destruction of habitats has been a primary driver declines, though climate change associated sea level rise are expected to accelerate loss. flora low-lying, relatively isolated islands is especially threatened when high richness intersects with vulnerability rise. Florida Keys represent hotspot for cactus diversity in the eastern United States, eight recognized, three which endemic islands....
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...
Maintaining native plant diversity through fire management is challenging in the wildland-urban interface. In subtropical South Florida, fragments of fire-dependent, globally imperiled pine rockland forest are scattered throughout urban areas. To determine effects recent frequency, major soil type, and fragment size on species composition, we measured understory vascular presence cover 162 plots distributed among 16 publicly-owned preserves 1995 2003. Fragments received either 0, 1, or > 1...
Abstract Plant translocation can increase the chances of long-term survival threatened plant species; nevertheless, be costly and challenging, with unknowns in pre- post-release phases, limiting success. Methodological advances have been made pre-release phase but monitoring site management (i.e., “aftercare”) are not always applied almost neglected literature despite being frequently effective for identifying mitigating unexpected threats (e.g., interspecific competition, herbivory) to...
We developed a monitoring program to assess the health of urban fragments pine rockland, globally critically imperiled, fire-dependent plant community, in order provide feedback for adaptive land management. Our results showed negative effects fire exclusion, including low native herb and grass cover, excessive leaf litter accumulation, high densities trees most twelve preserves sampled. quantitative evidence need instituting regular prescribed fires Miami-Dade County's rockland preserves,...
Premise of the Study Community phylogenetic methods incorporate information on evolutionary relationships into studies organismal assemblages. We used a community framework to investigate and biogeographic affinities calculate signal endemism invasiveness for flora pine rocklands—a globally critically imperiled ecosystem with significant portion its distribution in South Florida, United States. Methods reconstructed 538 vascular plant taxa, which represent 92.28% rocklands. estimated using...
The widely invasive grass Rhynchelytrum repens (Willd.) C.E. Hubb. invades globally-imperiled pine rockland forests of South Florida. To examine whether its spread into and persistence in undisturbed areas pose a threat to native species, we investigated the presence R. was associated with decline diversity abundance understory plants. We showed density class strongly reduction species diversity, high (20% cover) plots having five fewer than low (0.2%) ones. When separated by functional...
Abstract Species native to ecotones are often overlooked in restoration efforts despite the increasing rarity of ecotone habitat. In fragmented, fire‐suppressed landscapes, true may no longer exist. Restoration biologists interested reintroducing species must decide whether plant them historic maintained by manual thinning or opt for discrete areas that easier maintain. We investigated these two alternatives with Lantana canescens , a rare tropical shrub between pine and hardwood forests...
Extreme south Florida has suffered recent losses of butterfly populations and even species extinctions. Information about the life histories rare butterflies their host plants is needed to recover populations. We assessed urban fragments pine rockland for potential support federally endangered Strymon acis bartrami Anaea troglodyta floridalis. sampled mapped distribution larval plant Croton linearis used GIS data fire records rank each ten preserves suitability butterflies. Our findings...
Abstract Germination studies at the community level are crucial for understanding and predicting changes in species distribution patterns, particularly endangered plant communities. We investigated effects of dry (11–25% relative humidity) freezing (–18°C) storage conditions, phylogeny life-history traits (life-form, life-span, microhabitat seed dispersal mode) on germination percentage (GP) time to reach 50% ( T 50 ) 53 native pine rocklands South Florida, USA, a globally critically...
Misidentificationof Microsorum scolopendria in South Florida.-Microsorumscolopendria (N.L.

In Big Cypress National Preserve, the federally threatened Everglades bully (Sideroxylon reclinatum subsp. austrofloridense) is sympatric with its conspecific, more widespread relative, Florida reclinatum). this area of overlap, only reliable characters to distinguish two are cryptic, micromorphological traits abaxial laminar surface. order better understand distribution taxon, we used a combination habitat suitability modeling (HSM), field surveys, and microscopy. Using models inform...
We conducted a reintroduction program for rare goatsfoot passionflower (<i>Passiflora sexflora</i> Juss. [Passifloraceae]) that was possible only through the cooperative efforts of 4 different agencies, one private homeowner, and several volunteers. The included surveying collecting wild plants, nursery propagation, to 2 locations within historic range passionflower. Reintroductions tripled known population size this species. Early results show 90% transplants have survived date, with more...
Pine rockland is a globally critically imperiled ecosystem limited to the southern tip of Florida and nearby islands. Miami’s Richmond tract contains largest American assemblage pine species. Competing interests challenge management in this fire-dependent surrounded by urban development. In 2018, Fairchild Tropical Botanic Garden Miami-Dade County updated 1994 plan, complete with best practices, new developments, current data learned experiences. An analysis indicated non-traditional areas...
The poison ivy sawfly, Arge humeralis Beauvois, was previously known to feed only on ivy, Toxicodendron radicans (L.) Kuntze. However, in 2009, larvae were discovered southern Florida feeding poisonwood, Metopium toxiferum Krug and Urban. To better characterize the host range of A. humeralis, we compared larval performance T. M. toxiferum. Adults oviposited both plant species, days pupation survival adulthood similar. With exception longer 1st 4th stadia radicans, also Most mortality...
Recent reviews of rare plant reintroduction success indicate that far fewer studies have been conducted with seeds than whole plants, and these, less 10% established or had long‐term population persistence reported. Because seed reintroductions are relatively expensive reintroductions, determining ways to increase efficacy using establish populations has conservation benefits. In laboratory trials, we examined germination an endangered legume, Dalea carthagenensis var. floridana , endemic in...
Summary The genus Tephrosia (Fabaceae), the hoary peas, contain high levels of rotenone, which has a long history human use as fish poison. We examine distribution angustissima , in South Florida to clarify patterns genetic relatedness and shed light on plant movement before European contact. Several populations with taxonomic uncertainty exist neighboring Caribbean Islands. To relationships this group, elucidate conservation status Everglades National Park Big Cypress Preserve, we used...
