FIRE EFFECTS
SPECIES: Thamnosma montana | Mojave Desertrue 



IMMEDIATE FIRE EFFECT ON PLANT : 
Information was not available regarding the immediate effects of fire on
Mojave desertrue.  Mojave desertrue is probably top-killed or killed by
most fires.


DISCUSSION AND QUALIFICATION OF FIRE EFFECT : 
NO-ENTRY


PLANT RESPONSE TO FIRE : 
Mojave desertrue was present on a burn in the Sonoran Desert, Arizona,
within 4 years of a June fire [33].  The absolute cover value of Mojave
desertrue following controlled fires in a blackbrush community in
southwestern Utah is as follows [7]:

                                Absolute cover value (percent)  
Time elapsed since burning        mean     standard deviation 
unburned                          0.9       2.3
1 year                            0.5       0.8
2 years                             0         0           
6 years                             0         0
12 years                            0         0
17 years                            0         0  
19.5 years                       11.7       3.8  
37 years                         15.4      11.4

The 37-year-old site was dominated by shrubs and annual grasses.  Mojave
desertrue had the greatest absolute cover value of any other species on
this site [7].


DISCUSSION AND QUALIFICATION OF PLANT RESPONSE : 
NO-ENTRY


FIRE MANAGEMENT CONSIDERATIONS : 
For several decades after burning blackbrush communities, these sites
may be dominated by nonpalatable shrubs such as Mojave desertrue.
Therefore, prescribed burning is not recommended in blackbrush
communities to improve forage for livestock [33].
