Imperial County Road S-80 5 miles east of Ocotillo at BLM Plaster City ORV area, a mustard disaster ready to happen. Photo. 5/18/2005
County Road S80 - May 2005 - Raw data.
Results of a 70 mph windshield survey (or whatever the local
speed limits were), of three exotic Mustards: Either not present;
is present along roadsides or in medians; or is outside of the
roadside to the fence line or has moved from the roadsides to
infest adjacent land.
NS = None Seen. None of the three exotic Mustards of concern were seen along roadside ditches; or if divided highway, also not seen in the roadside median, or in lands adjacent to the road.
RS = Road Sides were infested. MED = In divided highways, in medians.
DES = One or more Exotic Mustards have moved from the roadsides into the desert, agricultural areas, or other lands adjacent to the roadsides. FL = Only found along the highway cyclone-fence line, but is far enough off the roadside to pose an immediate problem for the lands adjacent to the fences. At the time of the survey, did not appear to be moving off the fence line yet.
SPECIES SURVEYED for:
BT = Brassica tournefortii or Sahara Mustard
PM = Post miles along highways, and numbers indicate the
averages found not just at each post mile, but for 1/2 mile on
either side of the post mile marker.
