2018 National Meeting

CPC National Meeting at BRIT

This year CPC’s national meeting traveled to the Lone Star State, to the campus of the Botanical Research Institute of Texas (BRIT). BRIT is home to the ninth largest herbarium in the country, housed in a LEED Platinum certified building with almost 1.5 million specimens. BRIT scientists document the diversity of plant life and conduct research around the world in order to fulfill their mission “to conserve our natural heritage by deepening our knowledge of the plant world and achieving public understanding of the value plants bring to life.” BRIT shares its grounds and education programing with the Fort Worth Botanic Garden, the oldest botanic garden in Texas.

This annual three-day conference brought together the leaders in plant conservation at the CPC Participating Institutions to share and learn cutting-edge science and technology used to save rare and endangered flora.

The meeting was opened with a warm welcome from BRIT President and Executive Director, Dr. Ed Schneider.

Chairman of the Center for Plant Conservation Board, Peter Raven shared his opening remarks.

CPC President and CEO John Clark gave the “State of the CPC” address.

BRIT conservation research botanist Kim Taylor elaborated on the conservation programs at BRIT.

Invited speaker Christina Walters of the USDA-ARS National Laboratory for Genetic Resources Preservation, gave an excellent talk on the cutting-edge science of seed storage, noting the many challenges and opportunities that we have in efforts to end plant extinction. Her engaging and animated presentation provided for many in-depth discussions throughout the meeting.

Participants were asked to present a 5-minute “lightning talk” about a challenge they face in plant conservation at their institutions and how they overcame that challenge. From Hawai’i to the Southeast, and in between, the CPC Participating Institutions demonstrate the expertise, commitment, and tenacity to tackle some of major hurdles in order to Save Plants.

Here is a sampling a just a few:

“E Mau ana Ka Ōhi‘a — Perpetuating ‘Ōhi‘a”

Seana Walsh and Dustin Wolkis

There are new fungal pathogens that are threatening the Ōhi‘a (Metrosideros spp.) tree in Hawai’i. Rapid Ōhi‘a Death (ROD), caused by two taxa of Ceratocyctis, is killing large stands of Ōhi‘a forests on the island of Hawai’i. Preparations need to be made in case ROD spreads across the state. This involves collecting seeds, banking, and reciprocating of all Metrosideros taxa on all the islands for resistance testing and to possibly use for reintroduction at a later date. Because there were no established seed zones, “geographical areas where seed from an originating zone can be transferred to help ensure material is ecologically appropriate for the local environment,” provisional seed zones had to be created for the island of Kaua’i. This was done by the staff of NTBG and the Hawai’i Department of Land and Natural Resources, Division of Forestry and Wildlife. Currently, work is underway to collect between 6 and 20 million seeds from over 1,000 trees.

“Using a zoo model to conserve genetic diversity of critically endangered species ex situ”

Jordan Wood, Jeremie Fant, Andrea Kramer, and Kay Havens

“Genetics becomes important whenever populations become small (<100). This includes loss of genetic diversity from drift, increased expression of deleterious genes due to inbreeding, and limiting local adaptation. Since many species of plants are able to be seed banked, it is possible to maintain numbers well above these critical genetic thresholds. However, for exceptional species, which can only be maintained as living plants, or for critically endangered species where remaining individuals are already below these numbers, the need to consider the remaining genetic diversity becomes critical. Importantly, the management focus shifts from saving a population to preserving each genetically unique individual. When you have such small numbers, it is critical to know how each individual contributes to the overall genetic diversity remaining.” The Chicago Botanic Garden is working with the National Tropical Botanic Gardens in Hawai’i on a species management and breeding plan for Ālula (Brighamia insignis). The goal is to support the restoration of Ālula to the wild. This process includes working with scientists at the Chicago Zoological Society. These scientists have management software that uses “genetics and demography information to maintain the long-term health of their captive animals over the long term.” The software will be modified to work with not only preserving plants, but to “create resilient populations that can be used in reintroductions.”

“What’s new for Torreya taxifolia, North America’s rarest conifer?”

Emily Coffey, PhD, Ron Determann, Rebecca Byrd, and Carrie Radcliffe

One of the rarest conifers in the world is the Florida Torreya (Torreya taxifolia). It is endemic to northwest Florida and extreme southwest Georgia. A catastrophic decline in this species occurred in the mid-20th century as reproductive-age trees were killed by an until-recently-unknown disease, Fusarium torrayae. The species has not recovered and is now less than 0.22 percent of the original population. These remaining trees continue to be endangered by changes in hydrology, deer browsing, continued loss of reproduction capability, and fungal disease. Atlanta Botanical Garden has set up an in situ and ex situ seed experiment as part of the recovery effort for this rare tree.

Star Award

Ed Schneider

BRIT Executive Director

Each year the Center for Plant Conservation (CPC) presents the Star Award to honor those who demonstrate the concern, cooperation, and personal investment to conserve our imperiled native plants. This year the CPC’s Star Award was presented to Ed Schneider for hisdetermined efforts in advocating for plants and in leading three exceptional institutions towards ever-greater conservation outcomes” which “have helped save some of the nation’s rarest plant species from extinction.” For 30 years, Schneider has helped to save many of the endangered plant species on the CPC list and has been instrumental, in the words of CPC President John Clark, in “increase[ing] CPC’s capacity to care for these plants by bringing three participating institutions into the network.”

Following the award ceremony, the attendees were treated to a lively keynote address by Barney L. Lipscomb, the Dorothea Leonhardt Chair of Texas Botany and a prominent Texas botanist, on the history of botanical discovery in Texas. Barney highlighted the wealth of information available due to “collectors and collections over the last 197 years.” Lipscomb noted, however, that even though collections may be “leading the way to advances in plant science and conservation,” there is a current decline in collecting plants. The importance of these collections is in the wealth of information they provide—collections are “good for science and good for conservation in the 21st century.”

On Friday, May 4, the meeting continued at BRIT with more discussion about CPC Best Practice Guidelines and presentations by conservation officers and network partners. Following the day’s sessions, the group toured the Fort Worth Botanic Gardens and enjoyed lively conversations and dinner at the Gardens Restaurant.

Saturday Field Trip

Saturday began early as the group headed west to Eagle Mountain Park. The park sits at the heart of the Fort Worth Prairie Ecoregion, a region of thin limestone soils supporting vast expanses of open prairie and a wide array of regional endemic species. The thin, rocky soils of the region are not conducive to farming but are ideal for cattle grazing, giving rise to the unique cow-town culture of Fort Worth. The prairies today are highly threatened due to urban expansion of the Dallas-Fort Worth metropolitan area. Participants toured a remnant prairie, explored rare habitats, and experienced the breathtaking wildflower displays for which Texas is known.

As we bade farewell to the Lone Star State, we look forward to next year’s national meeting to continue working together on saving plants.
