Trees are Food Sources for Wildlife

Trees are crucial for the survival of many animals. Certain insects and mammals can only eat one specific type of tree, i.e. wildlife is better adapted to feed on native tree species than non-native ones, making them a vital source of food for local ecosystems. Therefore, it should be taken into consideration when planting trees and arboretums that they do not exclusively include exotic species, to avoid damaging the local ecosystem.

Leaves, acorns, berries, and nuts are all important parts of the tree, eaten by various types of animal.

Tree bark is a natural component of a beaver's diet. When vegetation is limited, particularly in the winter, deer and rabbits may eat tree bark out of necessity in these harsher conditions.

Tree roots share sugars with fungi through mycorrhizal networks, which then support insects and soil organisms that feed birds and mammals!

Did you know that tree sap is a food source? It provides sugars and nutrients for insects, birds, and mammals like squirrels.

Rotting trees are more nutritious than living ones – decaying wood has higher protein levels due to fungi and microbes, making it a richer food source for insects and woodpeckers!

Dead trees are still "food" for fungi and insects, which then become food for birds, bats, and small mammals, contributing to a circular ecosystem.

Trees act as a "pantry" for some animals – squirrels and jays store nuts inside trees, helping them to survive through the winter.

Trees often produce huge amounts of seeds at once (masting) to overwhelm animals, ensuring that some seeds survive. Additionally, mild toxins in leaves or seeds discourage over-eating, ensuring animals don’t destroy the tree’s food supply entirely. An amazing example of the "intelligence" of trees!

Acorns and nuts (especially from Beeches) fall directly beneath the tree, but are carried by Jays to other areas.
