VALUE AND USE
SPECIES: Philadelphus lewisii | Lewis' Mockorange 



WOOD PRODUCTS VALUE : 
NO-ENTRY


IMPORTANCE TO LIVESTOCK AND WILDLIFE : 
Lewis' mockorange is of minor importance as a forage species for
livestock [43].  Sampson [36] considered it poor to useless browse for
cattle and horses.  However, Shaw [37] reports that in riparian areas in
eastern Oregon, Lewis' mockorange is heavily browsed in areas accessible
to cattle.

Lewis' mockorange is a moderately important winter forage species for
deer and elk in the northern Rocky Mountains.  In southern British
Columbia, Lewis' mockorange is of moderate importance as a winter forage
species for white-tailed deer and Rocky Mountain elk, and of low
importance to other wild ungulates [4].  In Montana, a 1957 study based
on rumen samples showed that Lewis' mockorange constituted 2 percent of
mule deer diets in the winter and a trace in the summer [47].  In
northern Idaho, use by white-tailed deer was moderate, although a few
individual plants were browsed heavily [42].  Lewis' mockorange seeds
are eaten by quail and squirrels [46].


PALATABILITY : 
Although generally considered of low palatability, Lewis' mockorange is
browsed heavily at times [21,37,42,43].  New sprouts of Lewis'
mockorange are very palatable [1,21,36].  See FIRE MANAGEMENT for
discussion of Lewis' mockorange palatability following fire.


NUTRITIONAL VALUE : 
NO-ENTRY


COVER VALUE : 
Lewis' mockorange occurs in dense shrub habitats which probably provide
good cover for wildlife.  In north-central Washington, Lewis' mockorange
occurs in a riparian cover type which is preferred in both summer and
winter by mule deer for thermal and security cover [6].


VALUE FOR REHABILITATION OF DISTURBED SITES : 
NO-ENTRY


OTHER USES AND VALUES : 
Native Americans used the strong, hard branches of Lewis' mockorange for
bows, arrows, combs, tobacco pipes, cradles, and netting shuttles
[17,34].  Lewis' mockorange is cultivated as an ornamental, but
Philadelphus coronarius, a European species, is the most commonly grown
mockorange in the Northwest [39].  Lewis' mockorange is the Idaho state
flower [17]; it is illegal to collect Lewis' mockorange in Idaho for
export or sale [30].


MANAGEMENT CONSIDERATIONS : 
Lewis' mockorange is very sensitive to herbicide sprays [2,31].  Effects
of herbicides on Lewis' mockorange are described [27].
