Uses by native peoples
(Ethnobotany database)

Juniperus hosts caterpillars of 41 species
of butterflies and moths, in some areas.

Junipers are the winter host for 🍄︎⚕︎ fungal disease trellis rust (TR)  Gymnosporangium sabinae.  Adobe Acrobat Reader file

Which then transfers to nearby 🍐︎ pear  genus Pyrus as the ☀︎ summer host.  Then back again!

So in areas that may have this disease, do not plant these two hosts within 300 m (1000 ft) of each other!  (In most towns, 3 blocks, maybe.)
