I don’t know if these tumbleweeds are S. ryanii or not, but in previous years I don’t recall seeing them. Now they are all over Carrizo Plain National Monument as shown below, but also (see fenceline) they can be found stacked along anything that stops them, such as fencelines. They also make the bottoms of ravines all but impossible for hiking. They block roads fully in some places with jumbles 50 feet wide and 6 feet deep. See New species of tumbleweed is just as bad as its parents.
