Soil disturbance spreads noxious weeds
County's Weed Department (yes, there really is a "Weed Department")
weighed in on Christo's "Over the River" project. Spokesman
Larry Walker explains how construction, foot and vehicle traffic, and
other soil disturbances
spread weeds that are harmful to invaded environments.

SALIDA, COLORADO 81201
|"Our main concern is the spread and increase of noxious weeds along
the river corridor caused by river bank disturbances, heavy equipment
and increased traffic along
the roads and river banks."
Chaffee County Weed Department has been asked to give an opinion on
the Over the River Project on the Arkansas River. Our main concern is the
spread and increase of noxious weeds along the river corridor caused
river bank disturbances, heavy equipment and increased traffic along
roads and river banks. Noxious weeds increase rapidly when soil and
native vegetation is disturbed. The department has concerns that this
project will adversely affect the river ecosystem by spreading noxious
weeds along the corridor.
There is also a new invader along the Fremont/Chaffee county line that
causes great concern. Brassica elongata, or Elongated Mustard has be
identified in the Wellsville area in the last 3 years. In that period
has spread to infest over 100 acres and has jumped to the south side
the river and is moving along the highway. This species is acting as
perennial plant producing seed on stalks that break loose each year and
tumble dispersing seed as it rolls with the wind. The rosette remains
over winters to produce new seed the following year.
|"the Chaffee County Weed Department has justified
concerns that the 'Over the River' project will cause environmental
damage... costing the Counties,
BLM and CDOT thousands of dollars to control."
growing in extremely rugged terrain where it is
very difficult to reach to do control work. Fremont and Chaffee county
weed departments are very
concerned that this project could spread
Elongated mustard up and down
river corridor costing the Counties,
BLM and CDOT thousands of dollars
control. Due to the extreme terrain
that the plant can occupy it may
totally escape into surrounding areas
such as private and USFS lands.
Due to these problems the Chaffee County Weed Department has justified
concerns that the Over the River project will cause environmental
and significant weed management cost increases for all land managers
