VALUE AND USE
SPECIES: Baccharis halimifolia | Groundsel-Tree
WOOD PRODUCTS VALUE :
NO-ENTRY
IMPORTANCE TO LIVESTOCK AND WILDLIFE :
Grelen [12] lists groundsel-tree as a "desirable" browse species for
white-tailed deer, although it probably has little or no value for other
wildlife species and may be toxic to some [4]. Laboratory tests on mice
and chicks indicate that ingestion of more than 2 percent of an animal's
body weight in groundsel-tree foliage may be toxic. Visible symptoms of
groundsel-tree poisoning range from mild depression followed by recovery
to extreme listlessness and stupor followed by death. The toxic
compound in groundsel-bush attacks the hepatic and circulatory systems
[7].
PALATABILITY :
Groundsel-tree is unpalatable to cattle and often displaces more
palatable forage [4].
NUTRITIONAL VALUE :
NO-ENTRY
COVER VALUE :
Groundsel-tree provides emergency cover for muskrats when storm tides
sweep through southern Louisiana salt marshes [18].
VALUE FOR REHABILITATION OF DISTURBED SITES :
Groundsel-tree's tolerance of salt spray [20], and rapid colonization of
disturbed sites [21] may make it useful for disturbed site
rehabilitation in some situations. More often, it is considered a weed.
One eastern-Texas native-prairie restoration project reported that the
presence of invading groundsel-trees reduced forb diversity [13].
OTHER USES AND VALUES :
Hardiness, freedom from disease, and attractive fall foliage make
groundsel-tree an attractive ornamental. It may aggravate hay fever
symptoms for some people [4].
MANAGEMENT CONSIDERATIONS :
Baccharis species are problem weeds of rangelands, pastures, parks,
recreational areas, and floodplains. Mowing and broadleaf herbicide
treatments at 1- to 3-year intervals may provide control, although such
control methods are often not cost-effective. Phytophagous Brazilian
insects have been successfully used to control introduced Baccharis
species in Australia. Similar techniques show promise for use in the
United States [4].
