Stevens County Noxious Weed Control
Board This web site will help
you identify & control noxious weeds. Conventional & biological control
(BioControl) information and photographs are here. Maps & related
information are included.
Many tiny flowers are in each finger-like cluster at branch tips
Leaves look like cedar and are small and scale like on highly
branched slender stems
May have appearance of a shrub or a small tree
Bark on saplings and stems is reddish-brown
Biology and ecology
Grows as deciduous or evergreen shrubs or small trees, 5 to 20
feet tall
Both T. ramosissima and T. parviflora are used as ornamentals,
but have escaped and naturalized along streams, canals, and
reservoirs in the west
Aggressive colonizer forming single species stands in riparian
areas of arid landscapes
Secretes salt inhibiting growth of other plants
Extensive root system combined with a high evapotranspiration
rate can cause lowered ground water levels and dry up springs
and marshy areas
Control
P
revention Learn to
identify plants; know your property; beware of fill dirt and seed from
outside your areaBe careful with introduced ornamentals
Biological None known at this time
Cultural Competitive vegetative cover helps but cannot
prevent spread in susceptible sites
Mechanical Repeated digging can be effective
Chemical Several herbicides are effective at label rates
but care must be used around moist areas;
The
PNW Weed Management Handbook does not list Salt cedar for specific chemical recommendations
Where found
Ornamental plantings, usually
single plants, of both T. ramosissima and T. parviflora have been
noted here and there throughout Stevens County in residential areas.
No confirmed escapes and naturalization known at this time, but wet
sites within our more arid areas are potential locations for
infestation.
