The Elm Bark Beetles Get habitat from the elm tree, and in return The elm tree is protected by the beetles. Their symbiotic relationship is Mutualism. Both the Elm tree and the beetle benefits from this relationship
They used a bark canoe.
the birch bark makes the canoe sturdier :)
The elm tree bark is falling off due to a disease called Dutch elm disease, which is caused by a fungus that infects the tree and weakens its bark, leading to it falling off.
They adopted the Indian's swift, graceful bark canoe for water travel. They used bark from trees to make a canoe for water travel. They adopted the Indian's swift, graceful bark canoe for water travel. They used bark from trees to make a canoe for water travel.
Years ago, before the Europeans arrived, the Natives of north America that lived beside the rivers and lakes, developed a canoe whose skin was the bark of the birch tree. Birch bark can be stripped from the tree in such a way as to make long wide unbroken lengths of bark that can be laid onto the frame of a wooden canoe. Birch bark is water proof (as is all bark) and is also light enough to make carrying the canoe an easier task than the old idea of hollowing out a log.
The number of birch bark trees needed for one birch bark canoe typically ranges from 1 to 3 trees, depending on the size of the canoe and the specific design. A standard canoe may require about 10 to 15 large sheets of birch bark, which can be harvested from a single tree without killing it. Careful harvesting techniques ensure that the tree can continue to thrive and produce bark in the future.

yes
yes! they used it to make canoes

Dutch Elm disease is a tree disease that is spread by beetles. It is caused by a fungus carried by elm bark beetles, which feed on the bark of elm trees, introducing the disease into the tree's vascular system.
