Spent the day hiking the Sheyenne National Grasslands!
Spent a few hours just wandering over the endless aeolian (wind sculpted) dunes of the Sheyenne Grasslands, through Bur Oak Savanna clinging to dunes interspersed with upland prairie. Some of these Bur Oaks are very old despite their appearance. The well drained sandy soils that characterize the upland sites can shunt the growth of the oaks in dry years, compounded by their open exposure to repeated wind events, blizzards, fires...
The upland Oak Savanna and prairie are ecosystems of resilience and disturbance. Imagine what these oaks have seen through the decades!
