It occurs in habitats of mixed scrub forest and ridges and bluffs along small waterways, preferring well drained soil. These features make Arkansas oak rare and conservation difficult. It was recently upgraded to endangered status (IUCN 3.1) and at serious risk, without legal protection in most of its range (state threatened in FL) (9, 10). Bottlebrush Buckeye, Aesculus parviflora, is endemic to Alabama, southwest Georgia, and one South Carolina County, and is of conservation concern in North America. The species is considered G3-vunerable in NatureServe, with an estimate of less than 100 occurrences. Alabama populations are vulnerable (S3), Georgia populations are vulnerable to imperiled (S2S3), while the disjunctive South Carolina population is critically imperiled (S1). Aesculus parviflora currently has no legal protection, though considered rare by the South Carolina DNR. Acorns and Buckeyes are recalcitrant and unable to be stored long-term. The best enduring option for germplasm storage – living genetic resources that are maintained for plant breeding, preservation, conservation and other research – is to collect seed or other plant material from the 3 wild representing the widest possible range of genetic diversity found in nature, and growing the trees in botanical gardens, arboretums, and nurseries. To this end the Missouri Botanical Garden, Bellefontaine Cemetery, and AU Davis Arboretum have partnered on a Tree Gene Conservation Project to survey and collect Quercus arkansana and Aesculus parviflora in ex-situ collections as per our grant proposal (1). A total of four trips were carried out, over the span of seven months. Figure 1 - Map of localities surveyed for Arkansas oak (2017). White circles represent the populations of Quercus arkansana which were located and surveyed. Black circles represent population records that were unable to be relocated, and are presumed to be extirpated. Objectives/Goals 1. Survey and document occurrences of Quercus arkansana, especially disjunct, valuable, underrepresented and at risk occurrences from a wide geographical range. 2. Survey and document occurrences of Aesculus parviflora, especially disjunct, valuable, underrepresented and at risk occurrences from a wide geographical range. 3. Record threats to populations. 4. Survey acorn and Aesculus flower occurrence, to inform fall seed collection 4 5. Collect acorns, seed, and divisions of target species and distribute to partner APGA gardens. Daily Work Logs: Work Log: AL, GA, FL Scouting/Collecting Trip-May 2017 Submitted by David Gunn Wednesday, May 24th: Jared and I worked together getting supplies ready for scouting trip. Camping: Tents, sleeping bags/pads, stove, food, storage bins, and cooler. Tools: pruners, loppers, pole saws/pruners, extension pruners, shovels, trowels, buckets. Supplies: plant press, blotters, newspaper, baggies, pots, sphagnum moss, log books, paper towels, Physan disinfectant, GPS-Garmin and Trimble, chargers, car adapter. Stored all supplies in spare office at MBG Thursday, May 25th: I picked up Jared and his gear and we drove to MBG to meet Kyle at 6a; loaded supplies into the van (on loan from Bellefontaine). Double checked supply lists and got on road by 8a. Kyle followed me to my apt to drop off my truck. We drove 560 mi to Atlanta (Kyle driving), arriving at 6p (heavy traffic) and stayed night with Kyle’s friend, Parker. Friday, May 26th: We packed the van and got on the road by 7a.; Drove to Drummond Swamp in Bartow County to scout for Alnus maritima for possible future conservation initiatives; found small population near pullout (JEC 22). Explored nearby creeks and drainages for Aesculus populations-found none present. Jared: logged data and took GPS coordinates. Kyle: took photos and DNA samples, helped with van navigation. Dave: Drove van, took herbarium vouchers, handled logistics. Drove to Red Top Mountain S.P. in Cartersville, GA to hike homestead trail to get a feel for local communities and hone local ID skills. We returned to Parker’s home for the evening. Saturday, May 27th: Loaded gear into van and on the road by 7a. We drove to Pine Valley Mountain, GA to explore reputed Aesculus parviflora population in Bethlehem Creek-found no populations present. Drove 5 to Auburn University in Alabama to meet with Patrick Thompson and toured Davis Arboretum; Drove to Montgomery County to explore Jackson Creek-found population of A. parviflora (JEC 23); Drove to Pike County to explore Patsaliga Creek-found A. parviflora population (JEC 24). Drove to Forever Wild Pocosin Tract- scouted for and found Q. arkansana population (JEC 25). At each site, Jared: logged data and took GPS coordinates. Kyle: took photos and DNA samples, helped with van navigation. Dave: Drove van, took herbarium vouchers, logistics, Patrick: helped with ID, scouting and additional photos. Returned to Auburn and spent night at Patrick’s home. Bethlehem Creek, Georgia Sunday, May 28th: Packed up and got on road by 6:30a, with Patrick following us in his truck, to Fort Benning, GA. Met with Brian Waldrup, Lead Forester for Land Management Branch, at 8a. We drove around the base in Brian’s truck. We first visited site of former state champion Q. arkansana (JEC 26- 27), drove to another site and walked into large A. parviflora site located in a ravine (JEC 28). Jared took data and GPS, Dave dug divisions and took herbarium vouchers, Patrick dug divisions and scouted size of population, Kyle took photos, DNA samples, and helped pack divisions. We drove to another Q. arkansana site (JEC 29-30). Jared: logged data and took GPS coordinates. Kyle: took photos and DNA samples, helped with van navigation. Dave: took herbarium vouchers, logistics. Patrick scouted surrounding area, helped with ID of associated species, took photos. Patrick departed for Auburn. Jared, Kyle, and Dave continued with Brian, scouting several areas throughout base looking for additional A. parviflora sites-found none. Parted ways with Brian and drove to Bluff Creek Park to spend night. After dinner, all three of us packed divisions in wet moss and foil, and prepped for shipping the next morning. Kyle took some video of the process. 6 Monday, May 29th: Got on road by 6a to begin driving to Williams Bluffs Nature Preserve in Early County, GA, stopping along the way to ship A. parviflora divisions that were collected yesterday back to MBG, so Justin Lee could start propagation treatment. Arrived at Williams Bluffs and drove and hiked extensively throughout preserve to scout for A. parviflora and Q. arkansana. We located one small population of Q. arkansana along forest edge of power line right-of-way (JEC 31). Jared: logged data and took GPS coordinates. Kyle: took photos and DNA samples, helped with van navigation. Dave: drove van, took herbarium vouchers, logistics. Drove to Kolomoki Mounds S.P., stopping at several roadside sites where Q. arkansana populations have been spotted in the past; found none. Our thoughts are that populations either integrated and hybridized with Q. nigra or those original IDs were incorrect. We spent the evening camping at Kolomoki Mounds S.P. Tuesday, May 30th: Awoke at 6a, packed up camp, and drove to visitor’s center to explore possible Q. arkansana population, and found small stand near pump house #5 (JEC 32). On road by 9a, driving toward Apalachicola N.F. Spent whole day driving around forest, scouting for Q. arkansana sites, following old collections notes, and found none. Consensus was that area has possibly seen a lot of lumber removal and controlled burns, and that populations once recorded, no longer exist. We drove to Camel Lake campground to spend night. Wednesday, May 31st: On road by 8a; drove to Apalachicola Bluffs and Ravines Preserve. Met with Annie Schmidt, loaded gear into her truck, and visited Sweet Water Tract-East and scouted for possible Q. arkansana populations; found none present. Drove to Sweet Water Tract-West to continue Q. 7 arkansana scouting, found none there, either. We drove back to Camel Lake campground to spend the night. Thursday, June 1st: Awoke and broke down camp, on the road by 8a. We started driving toward Fort Walton Beach, stopping along several roadside sites to scout. We arrived in Fort Walton Beach, FL around 2p. Checked into hotel room, unloaded gear and took rest of afternoon off to research next collecting sites, call contacts, etc. Friday, June 2nd: Packed up gear for the day and drove to Eglin AFB, arriving at 8a, with plans to meet Ryan Campbell. Ryan was out sick, so instead met with Jared Barton (Forestry Dept.). Loaded gear into his truck, scouted and collected samples from several Q. arkansana sites (JEC 50-53). Jared: logged data and took GPS coordinates. Kyle: took photos and DNA samples. Dave: took herbarium vouchers. We returned to Fort Walton Beach to spend evening. Saturday, June 3rd: Load gear into van, checked out and on road by 8a, driving toward Fred Gannon Rocky Bayou S.P.
