Natural Habitat Traditional Cache

I recently spend a weekend in the Deschutes National Forest in Central Oregon.  I noticed that many of the dead trees (snags) and some logs had silver tags on them.  The tags read, "Wildlife Tree, do not disturb or remove."  When I got home I read up on snags, the information below comes from  https://www.nwf.org/Garden-for-Wildlife/Cover/Trees-and-Snags .

I have passed this snag/log combo many times walking on Blue Mountain trail 3.01.  

Dead Wood Good? How Dead Trees Help Wildlife

Wildlife species use nearly every part of a dead tree in every stage of its decay for things such as:

• A Place to Live—Many animals, including birds, bats, squirrels and raccoons make nests in hollow cavities and crevices in standing deadwood.
• A Food Source—By attracting insects, mosses, lichens and fungi, deadwood becomes a gourmet restaurant for wildlife looking for a snack.
• A "Crow's Nest"—Higher branches of snags serve as excellent look-outs from which wildlife such as raptors spot potential prey.
• A Hiding Place—The nooks and crannies of deadwood are put to good use by squirrels and other wildlife looking to store food.
• A Soil Refresher—Mosses, lichens and fungi all grow on snags and aid in the return of vital nutrients to the soil through the nitrogen cycle. Decaying logs on the forest floor also act as "nurse logs" for new seedlings.
•  
• Dead trees provide vital habitat for more than 1,000 species of wildlife nationwide. They also count as cover and places for wildlife to raise young in the requirements for Certified Wildlife Habitat designation.

• Snags - The name for dead trees that are left upright to decompose naturally.

  Logs - When a snag (or part of a snag) falls on the ground, it becomes a log—also very useful for wildlife habitat.

  By some estimates, the removal of dead material from forests can mean a loss of habitat for up to one-fifth of the animals in the ecosystem.
