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].
