“…King and Buck (2018) A recurring topic for many ODP were two leading factors affecting forest stand dynamics: historical land-use and drought. Land-use changes over time due to population movements of Native Americans and settlement by Euro-Americans showed a gradual effect on forest ecosystems and disturbance patterns as both groups cleared forests for agriculture, grazing, and logging, and changed fire regimes (Taylor 1965;Clark 2003;Allen and Palmer 2011;and Stambaugh et al 2013b). More recent effects due to urbanization include fire exclusion, J. virginiana encroachment, and introduction of non-native plant species (King and Cheek 2015;Hoff et al 2018;King and Buck 2018).…”

Dendrochronology, the study of tree-rings to help understand events of the past, is a growing body of research that has become well-established in scientific literature within the last century. Oklahoma is a distinct resource to dendrochronology as it exists at the eastern deciduous forests and western prairies/grasslands transition. The extent of dendrochronological research conducted in Oklahoma has not yet been determined. A literature review was performed to catalogue and quantify dendrochronological research for Oklahoma. Thirty-seven written works were identified ranging through years 1923 to 2018. Nine research topics were developed to aid publication synthesis, with climate reconstruction, fire history, and stand dynamics being the most frequently encountered topics. Reviewed publications indicated that humans and climate, specifically drought, largely impacted Oklahoma forests historically, and remain a current threat. Results provide a detailed resource of dendrochronological applications within Oklahoma that spans the past century. Presented literature can be referenced for future Oklahoma dendrochronology studies, with presented knowledge also benefiting studies of similar forest types elsewhere.

“…The Stand Dynamics research topic contained the highest number of ODP with the most diverse main study species: P. echinata (Taylor 1965;Cerny et al 2016), J. virginiana (Edmondson 2006), Quercus (Therrell and Stahle 1998;Clark 2003;Clark and Hallgren 2003;Clark and Hallgren 2004;Clark et al 2005;King and Cheek 2015), and F. pennsylvanica (King and Buck 2018). Numerous forest types/locations were assessed: upland Quercus-Pinus stand (Taylor 1965), Shortleaf Canyon (Cerny et al 2016), upland Cross Timbers (Therrell and Stahle 1998;Clark 2003;Clark and Hallgren 2003;Clark and Hallgren 2004;Clark et al 2005;Edmondson 2006), an urban forest (King and Cheek 2015), and a lakeside bottomland hardwood forest (King and Buck 2018). Many factors leading to forest composition changes were evaluated in the Stand Dynamics research topic.…”

“…Stand Dynamics ODP's methodologies and results were distinct from all other ODP. Taylor (1965) was the first analysis of P. echinata in Oklahoma at its western range and Cerny et al (2016) documented its range expansion. Therrell and Stahle (1998) developed a GIS model that identified soil type to help predict ancient Cross Timbers forest tract locations: a new utilization of dendrochronology.…”

“…Some tree species were investigated less frequently as main species within the ODP: Fraxinus pennsylvanica Marshall (King and Buck 2018), Pinus echinata Mill. (Taylor 1965, Stambaugh et al 2013a, Cerny et al 2016 and Prunus angustifolia Marshall (Dunkin et al 2008). Juniperus virginiana L. was the third most examined species and the main study species for six ODP (Butler and Walsh 1988;Engle and Kulbeth 1992;Edmondson 2006;Dunford et al 2007;Hammer 2012;Bode 2015; Figures 2 and 3).…”

This issue of the Oklahoma Native Plant Record contains two dendrochronology reports, a phenological study of Oklahoma Asteraceae, and a study of the effect of cold stratification on germination of seeds of a native plant. These studies provide evidence of how land-use changes and abiotic factors affect Oklahoma plant communities and native species as well as provide insight into how future changes could impact our native flora.Chad King from the University of Central Oklahoma investigated the growth patterns and ages of trees at Martin Park Nature Center in north Oklahoma City. He reports that some trees in this park are approaching a century in age. Through the analysis of tree-rings, he was able to determine when trees of various species became established, and document variation in annual growth over time, indicating periods of growth suppression and growth release that might be due to land-use practices after the park was established in 1963.John Unterschuetz and Abigail Moore from the University of Oklahoma, and Jennifer Messick from the University of Central Oklahoma investigated the flowering phases of herbarium specimens of four native Asteraceae (sunflower family) species that had been collected since the early 1900s. Their goal was to determine if there was evidence of shifts in flowering times related to changing climatic conditions.Carmen Esqueda and Chad King of the University of Central Oklahoma provide a literature review of dendrochronological research conducted solely within the state of Oklahoma, beginning almost 100 years ago. Common research topics included age-diameter/growth rate, stand dynamics, climate, fire history, and some combinations of these topics. Post oak, blackjack oak, and eastern redcedar were the most frequently studied species. The authors identify understudied species and research topics that might stimulate additional dendrochronological research in the state.Samantha Coplen from the University of Central Oklahoma investigated the effect of cold stratification on germination of seeds of the pitcher sage, Salvia azurea var. grandiflora. Studies such as this, by documenting the germination probability of seeds exposed to different lengths of cold stratification, can give insight into whether climate change could reduce germination probability in the future. This issue's Critic's Choice essay was written by Paul Buck for the Fall 1998 Gaillardia. It describes his attempts to verbalize what I suspect we all experience when we take time to reflect on the immense beauty of Oklahoma landscapes. He encourages us to extend our observations past dusk to experience the transition in sights, sounds, and scents from daylight to dark.Please consider publishing your work in the Oklahoma Native Plant Record. It is listed in the Directory of Open Access Journals, is abstracted by the Centre for Agricultural Bioscience International, and can be accessed by researchers around the world.
