Ensuring Safety: Trees that are dead or structurally compromised can do an immense amount of damage actually. For instance, a decaying oak tree in a residential backyard might randomly shed large branches or topple over during mild storms! There’s actually been many such cases of branches falling on people, causing irreparable damage if you know what I mean. 

Post-Storm Damage Control: Natural events like hurricanes, earthquakes, tornados, etc. Can inflict severe damage on trees. In coastal regions, for example, palm trees may become partially uprooted or have broken limbs after a hurricane. Getting rid of these damaged trees stops them from falling apart piece by piece and hurting someone or damaging something in the future in future storms or collapsing unexpectedly.

Creating Space for Development: Maybe you want to renovate your backyard, or maybe you want to just move away this inconvenient tree that’s in the middle of your back yard and plant another one at the side!

Preventing Disease Spread: Believe it or not certain tree diseases, such as Dutch elm disease, can rapidly spread from one tree to another. If an elm tree in a neighborhood becomes infected, removing it promptly can prevent the disease from affecting other elms in the vicinity, preserving the local tree population.

Protecting Infrastructure: Trees growing too close to power lines or buildings can cause some pretty big issues. For instance, a large maple tree with branches entangled in electrical wires can lead to power outages or fires. Certain tree roots can actualy even come from underground and shift the tiling in your house or community!
