Time Lapse Video Shows Trees Give Visual Clues as They Rehydrate Each Spring

Time lapse video shows trees give visual clues as they rehydrate each spring

With the arrival of spring a few weeks ago, new buds and colors on the trees started to appear. Along with that new growth, a UBC Okanagan researcher has determined that some trees in spring also provide simple, visual clues—raised or lowered branches—to indicate that they are rehydrating or water-stressed.

New UBCO research says trees give visual clues as they rehydrate each spring

By using high-resolution sensors on a tree's stems and time-lapse photography, UBC Okanagan researchers can watch for the visual clues some trees present when water stressed. With the arrival of spring a few weeks ago, new buds and colours on the trees started to appear. Along with that new growth, a UBC Okanagan researcher has determined that some trees in spring also provide simple, visual clues--raised or lowered branches--to indicate that th…
