VALUE AND USE
SPECIES: Ambrosia deltoidea | Triangle Bursage 



WOOD PRODUCTS VALUE : 
NO-ENTRY


IMPORTANCE TO LIVESTOCK AND WILDLIFE : 
According to Stubbendieck and others [28], triangle bursage is
worthless as forage for livestock.


PALATABILITY : 
Triangle bursage is unpalatable [31].  McAuliffe and others [43] report that
it is highly unpalatable to mammalian herbivores.


NUTRITIONAL VALUE : 
NO-ENTRY


COVER VALUE : 
NO-ENTRY


VALUE FOR REHABILITATION OF DISTURBED SITES : 
Triangle bursage may stabilize critical areas such as surface-mined
lands in arid regions.  It can be established by direct seeding or with
containerized plants [30].


OTHER USES AND VALUES : 
The paloverde/triangle bursage community is an aesthetically attractive
plant community, and it is often preserved as a form of landscaping when
urban development occurs [20].


MANAGEMENT CONSIDERATIONS : 
Domestic grazing has caused a decrease in grasses and subsequent lack of
fuel for burning in the Sonoran Desert.  As a result, bursage (Ambrosia
spp.) has increased in the Sonoran Desert [2].  During a 30-year period
of protection from grazing, triangle bursage decreased while perennial
grasses and palatable shrubs increased [1].  Hessing and Johnson [11]
found that removing woody plants, including triangle bursage,
contributed to greater herb growth.

Because of its dense, low-lying canopy, triangle bursage may protect the
seedlings of other species from herbivory.  McAuliffe [17] found that
rabbits consumed a greater proportion of seedlings in the open than
under triangle bursage.

Triangle bursage is the principal nurse plant for saguaro at Organ Pipe
National Monument.  Its shade reduces maximum soil surface temperatures,
and it also provides a microhabitat with elevated soil nitrogen levels
[9].
