The Arnold Arboretum of Harvard University has launched a 10-year initiative to expand and refine our collections of living plants–The Campaign for the Living Collections. This cross-institutional effort focused on plant exploration, collection, and production aims to enhance the Arboretum’s resources for research and conservation. Arnold Arboretum Manager of Horticulture Andrew Gapinski and Director of Operations Stephen Schneider just returned from an 11-day expedition through the Republic of Georgia. Below, read Andrew’s report from the field.
I write this post over the Black Sea as I travel on a return flight from Batumi, Republic of Georgia to Istanbul, Turkey and then onward to Boston. While building a collegial relationship with our Georgian partners, we collected seed, herbarium vouchers, and associated collections data, as well as compiled notes on species occurrence for future plant collecting trips. This expedition provided follow-up to a scouting and partnership building trip Steve participated in earlier this year. Throughout our journey we were joined by colleagues from the National Botanical Garden of Georgia (NBGG) in the central city of Tbilisi and the Batumi Botanical Garden (BBG) located on the Black Sea. I leave Georgia with immense gratitude and deep respect for the Georgian people, their history, and culture, and a fascination with the richness of the region’s flora, geology, and remarkable natural beauty.
Our trip started on September 27 with a late night flight (11:30pm) out of Boston Logan International direct to Istanbul. Following a five-hour layover, we boarded our flight to Tbilisi, Georgia’s capital and largest city (1.5 million people, elevation: 380-770 m), arriving early on the morning of September 29. We were greeted at the airport by Grigoli (“Gigo”) Otari Deisadze, a field botanist with the NBGG and our travel companion, who would accompany us for the duration of our expedition. As he drove us to the hotel (around 1:00am), we made quick plans with Gigo to meet again later that morning to head to the heart of the city to walk about, finalize plans for the coming weeks, and meet and visit with staff at NBGG.
Gigo dropped us off curbside along the Mtkvari (or Kura) River, to explore the cobblestone streets of Tbilisi on our own, grab a quick coffee and khachapuri (a pizza-like Georgian staple of bread and cheese), and handle final preparations (e.g., currency exchange). Tbilisi is located in Georgia’s central valley that runs west to east between the Greater Caucasus Mountains along the country’s northern border and the Lesser Caucasus to the south. The humid continental climate in this east/central section of the country offers hot humid summers and moderate to cold winters (similar to that of warmer parts of Massachusetts down to New Jersey, extending west below the Great Lakes to Nebraska and Kansas). Faces, foods, and flora captured our senses and signs of Tbilisi’s 1,500+ years of history were beaming around every corner—from active archeological digs unearthing stone foundations and clay wine vessels to the Georgian, Russian, and Persian architecture illustrating stories of past occupation. A giant monument on the nearby Sololaki Hill called Kartlis Deda (The Mother of Georgia) watches over the city wielding a sword in one hand while offering a bowl of wine in the other—a symbol both of their long history of struggles and resilience and the welcoming nature of the Georgian people for those who come as friends.
Saguramo Range, September 30 – October 1, 2016Gigo, Tolcha, Steve, and I headed out early Thursday September 30 to collect in the outskirts of the city of Mtskheta—one of Georgia’s oldest cities and first capital—northwest of Tbilisi 20km (12 mi). We planned to focus our efforts on the roadsides leading to the Shiomgvime Monastery (The Church of St. John the Baptist), which by the end of the sixth century was the largest monastic community in Georgia (around 2000 monks). We found ourselves in a scrubby plant community—clearly, heavily cut for lumber and fire wood and grazed over the centuries. Paliurus spina-christi (Jerusalem thorn), Rhamnus pallasii (black tangras), Ligustrum vulgare (common privet), Fraxinus excelsior (European ash), Quercus iberica (Georgian oak), Carpinus orientalis (Oriental hornbeam), Jasminum fruticans (wild jasmine), and several species of juniper (Juniperus sp.) were abundant in these areas.
After making several collections between 550-650 meters, we headed back into town for lunch and a visit to Svetitskhoveli Catherdral, an UNESCO World Heritage Site dating (in its present form) to 1029 and Georgia’s second largest church. Afterward we headed northwest to the Tbilisi National Park (aka Sagurmo Reserve), Georgia’s oldest National Park, established in 1973. We traveled along the winding gravel road leading to the Zedazeni Monastery near the summit of Mt. Saguramos (1385 m). This dense forest was dominated by Fagus orientalis (Oriental beech), Carpinus caucasicus (hornbeam), and Quercus iberica (Georgian oak). We made collections of several species including Tilia cordata (littleleaf linden), Fagus orientalis (Oriental beech), and Ilex colchica (Black Sea holly). The next day we continued our work northeast of Tbilisi in the province of Kakheti in the Gombori Range—several additional collections were made including Mespilus germanica (common medlar), Crataegus pentagyna (smallflower black hawthorn), and Euonymus latifolius (broadleaf Euonymus). On the drive back to Tbilisi, we stopped in to the Ujarma, an important fortress town of the Early Middle Ages, which sits atop a hill overlooking the Lori River Valley. We headed west the following morning.
