Abstract/Contents:"Cool season turfgrass species are well adapted to cool weather but can be damaged during winter months by a variety of different winter conditions. Currently there is no reliable method for predicting when different environmental conditions will cause damage. In Central Oregon several golf courses experience substantial localized winter kill suggesting small variation is climate can result in this problem. This project aims to identify the various micro-environmental conditions that cause localized winterkill. This trial was initiated in November 2021 and will conclude in December 2023. For this study data is collected from Black Butte Ranch in Sisters, OR, Widgi Creek Golf Club and Broken Top Golf Club in Bend, OR, and the Woodlands Golf Course in Sunriver, OR, where localized winterkill has historically occurred. Environmental conditions, CO2 and O2 flux at a 1.27 cm soil depth, as well as soil temperature (C) and soil volumetric water content at 15.24 cm, 7.62 cm, and 1.27 cm soil depths, and photosynthetically active radiation at the surface, are measured every 15 minutes. Monthly DJI Inspire II drone flights equipped with a Sentera 6x multispectral sensor with thermal are being used to assess red (670-30 nm), green (550 to 20 nm), near infrared (840-20 nm), red edge (715-10 nm), RGB (20 MP) as well as surface temperature (C). Grass genus and species population dynamics are being assessed in the spring, summer, and fall in areas that experience damage, and undamaged areas at each location. Preliminary results show increases in turf loss in areas that are shaded, and where the predominant grass is Poa annua at greens height. Exposure to extreme temperature swings as the result of no snow cover also resulted in turf loss at several sites."
