Stop number three is still fairly dry, but the vegetation has changed
significantly as you have moved into an area with a few scattered
pinyons and junipers but also with a large amount of shrubs and
grasses. The shrubs at this stop include sagebrush, mountain-mahogany,
and Wood’s rose, but most of the vegetation is either Gambel
oak or serviceberry. Gambel oak is one of the only three oaks native
to Utah, and the only one that grows in this area.
Gambel
oak, also known as scrub oak, is the multi-stemmed tree with
dark green, lobed leaves. It typically doesn’t reach more
than 10 feet high. As you walk or drive around, try and find the
two growth forms for Gambel oak. The thick, dense shrub form limits
access to the young leaves and acorns as food for wildlife and livestock.
The larger tree form allows grass to grow beneath while providing
both food and shelter to deer, elk and other animals. Gambel oak
is also unusual amongst oaks in that it will sprout new shoots quickly
when the tree is either grazed heavily or burned; because of this
characteristic, it is often the first tree in these areas to come
back after a fire.
Serviceberry
is another shrub-like tree with small rounded leaves that is quite
common in the area. In the northwest corner of the intersection
at this stop you will find a thick stand of serviceberry. The entire
plant is considered an important forage species for wildlife, including
the small apple-like fruits that appear on the shrub in the summer.
