<\/p>\nOne of the best things about nature is that it\u2019s always changing.<\/p>\n
Each season brings its distinctive colors, and with that comes<\/p>\n
joy and feelings of excitement. From pinkish blossoms to yellow leaves,<\/p>\n
nature is breathtaking all-year-round.<\/p>\n
However, there are trees out there whose trunks are white,<\/p>\n
and that\u2019s not because of the seasons, but because people paint them, and now you\u2019ll learn why.<\/p>\n
One of the reasons is because the white color protects the bark from sunscald,<\/p>\n
which is basically the plant version of sunburns, a condition that causes<\/p>\n
<\/p>\n
damage to the cambium layers and leads to dehydration. The white color acts like sunblock and prevents cracking.<\/p>\n
In case the bark splits, it becomes more vulnerable to insects, fungus, and other diseases.<\/p>\n
This painting is usually done during the winter when fluctuating temperatures from chilly nights to sunny days can damage the bark.<\/p>\n
\u201cThis type of painting is typically done on thin-barked residential trees or orchards,\u201d<\/p>\n
says Christopher Evans, extension forestry and research specialist at the University<\/p>\n
of Illinois Urbana-Champaign. \u201cPainting the trunks white is said to moderate<\/p>\n
the daytime heating of the bark and lessen the chances of sunscald injury.\u201d<\/p>\n
If damaged from sudden thaws and freezes, trees, especially those bearing fruit,<\/p>\n
are left in a vulnerable state. In cases of severe injury, the damage can<\/p>\n
be fatal and by applying heavy latex paint (or a specially designed formula)<\/p>\n
to a tree trunk can help protect trees from harsh winter weather.<\/p>\n
Other reasons are that painter tree trunks are more visible, especially<\/p>\n
when they are planted near the road. This may prevent any accidents as drivers are aware there are trees out there.<\/p>\n
\u201cBasically, it marks the tree in an inconspicuous way,\u201d Ken Fisher, assistant<\/p>\n
forester for the Boulder Parks and Recreation Department, said. \u201cA lot of people don\u2019t<\/p>\n
even notice it, but it alerts our contractor that this is the tree we\u2019re talking about.<\/p>\n
We\u2019ve been using paint dots for 25 years or so now, so some trees have several paint dots on them.\u201d<\/p>\n
Forest trees also get paint to indicate which of them is hazardous or safe, or simply mark private property.<\/p>\n
\u201cIn some places, trees with nests of rare or endangered species are marked,\u201d Evans says.<\/p>\n
\u201cThat is the case with the federally endangered red-cockaded woodpecker in the Southern United States. Their tree nests are generally marked with a white paint ring.<\/p>\n
\u201cBasically, there aren\u2019t any hard and fast standardizations for the use of marking paint in forestry.<\/p>\n
\u201cThat can lead to confusion when trying to generalize the meaning of different symbols and colors.\u201d<\/p>\n
