Increasing Seed for Restoration of Rare Annuals

Screenshot of Mike Kunz video

Michael Kunz, North Carolina Botanical Garden Populations of rare plants can fail to produce enough, or any, seed to support reintroduction efforts. This is particularly true for rapidly declining or recently extirpated species or populations. One solution to this problem is to increase the number of seeds through ex situ propagation and seed collection. Amaranthus pumilus is a federally endangered […]

Cheryl Peterson, Bok Tower Gardens Dicerandra immaculata var. immaculata (Lakela’s Mint) (Lamiaceae) is a short-lived perennial endemic to the Atlantic Coastal Ridge. It has only a three-mile historical range and few remaining populations. Population modeling predicts near complete loss of plants within eight years unless habitat is improved enough to support large enough populations to withstand stressful events such […]

Alexandra Seglias (Denver Botanic Gardens), Nicola Ripley (Betty Ford Alpine Gardens), Brittany Roberts Marshall (Betty Ford Alpine Gardens) Alpine ecosystems are particularly vulnerable to climate change. The Denver Botanic Gardens are seeking to protect rare species from these regions, banking seeds from multiple Alpine populations by maternal line. However, collecting seed from these remote areas […]

Melissa K. McCormick, Dennis F. Whigham, Rachel Rock-Blake, Hope E.A. Brooks North American Orchid Conservation Center (NAOCC) and Smithsonian Environmental Research Center (SERC) Orchids are widely threatened and endangered worldwide, but efforts to conserve and restore them has been limited by not knowing about the pollinators and fungi they need to grow and reproduce. The […]

Citizen Scientist-led Efforts to Save a Species: Safeguarding the Running Glade Clover, Trifolium calcaricum

Margi Hunter, Tennessee Naturalist Program, Cooper Breeden, Southeastern Grasslands Initiative, Austin Peay State University, Tennessee Plant Conservation Alliance The lack of funding and resources necessary to conserve many of our most imperiled species and communities is a ubiquitous problem. In the absence of traditional support, more grassroots and citizen-led efforts are essential to ensure the survival […]

How to Conduct a Plant Reintroduction with the Help of Volunteers

Seana Walsh, National Tropical Botanical Garden When conducting plant reintroductions with the help of volunteers it is useful to do a measure of advance planning. Considerations might include such items as taking into account how many volunteers are attending and making sure that there are enough tools and gloves available. It is important to be certain […]

CPC Best Reintroduction Practice Guidelines: Astragalus bibullatus Case Study

CPC Best Reintroduction Practice Guidelines: Astragalus bibullatus Case Study Matthew Albrecht, Missouri Botanical Garden (SePPCon 2016) Reintroduction is a critical component of rare species conservation with the goal of continuing evolution in a natural context. Within the southeastern U.S. 81% of recovery plans include reintroduction as a proposed conservation action, while in Hawaii almost all plant […]

Trees Will Adapt, Migrate or Die

Trees Will Adapt, Migrate or Die Barbara Crane, US Forest Service, National Forest System (SePPCon 2016) Barbara Crane, USFS, describes special considerations for trees.  Because the are long-lived, they cannot respond quickly to multiple threats from pathogens, fire, drought and climate change. Rates of historic migration of 300 to 1200 ft/yr cannot keep up with the […]

Planting in a Riparian System

Johnny Randall, North Carolina Botanical Garden This video reviews an experimental technique that refines optimal practice for planting the federally endangered harperella (Ptilimnium nodosum) along a river. After selecting a suitable site, obtaining permission, and propagating many plants, North Carolina Botanical Garden staff and volunteers planted 70 seedlings planted into replicated plots of terracell, coir, […]

The making of a Super Bloom: large-scale reintroduction of an endangered California annual

Vanessa Handley, University of California Botanical Garden University of California Botanical Garden (UCBG) has long been engaged in recovery efforts for State and Federally endangered large-flowered fiddleneck, Amsinckia grandiflora. Initially UCBG staff focused on creating a substantial seed bank for the species and, through nursery augmentation of wild-collections, generated a bank of over 100,000 seed […]

Trials and tribulations in restoring Showy Stickseed (Hackelia venusta)

Wendy Gibble, University Of Washington Botanic Gardens Hackelia venusta (showy stickseed) is a narrow endemic plant known only from one population in central Washington. It was listed as an endangered species in 2002 when the population was estimated at 600 plants spread over 40 acres. The most recent survey in 2012 documented 477 plants. Building […]

Standards for documenting and monitoring plant reintroductions

Matthew Albrecht, Missouri Botanical Garden Monitoring is a central component of reintroduction programs, but often receives less attention from practitioners than the preparation or implementation phases of a project. A well-designed monitoring program can detect changes in the environment over time, identify new threats that emerge at the reintroduction site, determine drivers of growth rates […]
