Cal. 78 PM 28.5 Imperial County west of dunes--"It's coming!"

Cal. 78 PM 60 Imperial County, mustard in ditch just wanting to colonize BLM land and Chocolate Mountains.

Results of a 70 mph windshield survey (or whatever the local speed limits were), of Sahara Mustard (Brassica tournefortii): 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 = No Sahara Mustard was 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 with Sahara Mustard. MED = In divided highways, in medians.

DES = Sahara Mustard has 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.

(Landmarks and other notes on other exotics or native plants will be in parentheses)

Survey 5/17/2005, notebook 193, pages 41-45.
