Summary

UW_Olallie_photo_metadata & image files: These are the raw timelapse photographs. The date/time stamp is inaccurate for the camera deployed in the open (at the SNOTEL) due to a programming error. This timestamp is one day early (i.e., subtract 1 day from the timestamp when using these data). Also available is metadata for two timelapse cameras and their associated snow depth poles (two visible in each camera's field of view) deployed at Olallie Meadows SNOTEL during water year 2015. One camera was deployed in the open area that is the Olallie Meadows SNOTEL station (the snow pillow is in the field of view). The other camera was deployed in the adjacent forest, approximately 60 m to the southeast of the SNOTEL. UW_Ollalie_snow_camera: [...]

Purpose

Climate change is projected to cause earlier snowmelt, with potentially serious consequences for terrestrial and aquatic ecosystems and for municipal and agricultural water supplies. However, if forests can be managed to retain snow longer, some of these environmental and financial impacts may be mitigated. Recent results from our research team demonstrate that in areas with relatively warm winters, strategically-cut forest gaps could offset climatic warming by increasing snow retention on the landscape and delaying runoff. However, in areas with colder winters, the opposite is true, as snow lasts longer under the forest canopy. We will map these climate-forest-snow interactions across the Pacific Northwest, predicting how forest change is likely to affect snow duration in different locations and testing those predictions against careful observations from our field sites and a network of citizen scientists. Working with regional forest and water managers, we will identify strategies for applying these findings to decision-making, linking climate-forest-snow interactions to ecohydrologic conditions important to management. Results from this project will help managers to act strategically to maximize snow retention (protecting forests in some areas while opening gaps in others), providing more water later in the season for hydropower, agriculture, and fish flows.
