Beyond Beautification: Trees Reduce Violence

Beyond Beautification: Trees Reduce Violence

by | Jun 25, 2026 | Blog

In neighborhoods, trees are responsible for providing shade, a place for kids to play, beautiful scenery, and the increased presence of wildlife. The benefits seem to be endless. Over time, many have tried to correlate the presence of trees in a neighborhood with an increase in crime. They would blame the lack of visibility that trees create, giving criminals a window to act. However, the opposite has proven to be true.

The presence of trees in a community has been associated with a reduction in crime and violence. One influential study that has validated this claim was conducted in Baltimore, Maryland. In collaboration with the National Forest Service, the University of Vermont compared neighborhoods throughout Baltimore based on their tree coverage. To control for external variables, the neighborhoods compared had similar levels of income, housing age, race, housing type, population density, and additional factors. By controlling these factors, the study confidently concluded that in Baltimore neighborhoods where the tree canopy was 10% higher compared to other Baltimore neighborhoods, occurrences of violent crime were 12% lower.

Trees are not the cause of lower crime, but the results of this study create an association between the amount of trees in an area and the levels of crime in that area.

So, while trees will not offer the same deterrent that a video-camera doorbell or a ‘secured by ADT’ sign provides, trees may play a role in reducing neighborhood crime while improving your physical and mental health, and many other aspects of your life.

Similarly, a 2017 study conducted in Philadelphia, PA, asked men to retrace the paths they had walked before becoming a victim of gun violence. Using map layers, researchers placed a map with tree locations on top of the victims’ paths. Controlling for the time of day, researchers found that being under tree cover resulted in lower incidences of gun violence. Again, this is an association, similar to the last study, though it is important to note that

While these associations do not prove causation, it is important to note that trees seem to produce endless benefits. Planting trees in hopes of reducing crime could result in a source of food, a place for kids to play or read a book, or a new spot to birdwatch! The positives outweigh any negatives in this situation!

At GHEP, we are dedicated to addressing the social determinants of health and human development in order to eliminate disparities in health and education, one of which is safe neighborhoods and affordable housing. By investing in trees for your neighborhood and your communities, you know that you are not only beautifying your neighborhood, but you are doing your part in making your home safe! Do not wait; free trees are available through the Family Tree Adoption Program, which can be accessed at https://globalhealthprojects.org/tree-reservation/

You Just Planted a Tree: How to Ensure it Thrives!

You Just Planted a Tree: How to Ensure it Thrives!

by | Jun 23, 2026 | Blog

Trees are often seen as very self-sufficient and low-maintenance. This is, for the most part, true; however, newly planted trees often require some care to ensure that they get properly adjusted to their new environment and grow healthily. Studies have shown that the years of a tree’s establishment, which describes the first five years of the tree’s life, are accompanied by the highest mortality rates. Following these steps will reduce the chances of mortality, ensuring that you have a healthy, happy tree!

Water your tree!

While adult trees do not need to be consistently watered, young trees need to be given a consistent supply of water. Young trees should be watered every day for 2 weeks after planting. To water your tree, use a garden hose or a pitcher to water the soil around the tree, careful to avoid wetting the trunk, as this could promote fungus growth. While daily watering is recommended, if the ground around your tree is already moist, do not water it. Following the initial daily watering for 2 weeks, water your tree 2-3 times a week, and eventually once a week.

Protect your tree from wildlife.

If you notice damage on your tree similar to the image on the left, it is likely that rabbits or squirrels are likely using your tree bark as a snack. This is extremely harmful to the young tree, as it can stop sap from properly circulating the tree and expose the trunk to fungus, sometimes resulting in the death of the tree. To prevent this, consider purchasing a mesh tree guard to keep small animals away until your tree has grown thick enough bark to defend itself.

 

Should I prune my new tree?

You do not want to prune your new tree immediately. If the tree has damaged branches or intersecting branches, feel free to prune those. However, refrain from any cosmetic pruning as you do not want to slow tree growth or root development during its formative years. The establishment years of your tree should consist of nurturing your tree and providing the water and resources it needs to grow. Once your tree begins to grow and mature, cosmetic pruning will be more appropriate.

Look out for the spotted lanternfly! The spotted lanternfly, as shown to the left, is an invasive species that has been prevalent on the east coast for the past couple of years. While the spotted lanternflies are not known for killing trees, they can cause some damage. While feeding on a tree’s sap, spotted lanternflies discharge a sugary substance onto the tree that can cause mold to grow. This is not a significant concern if there are a few lanternflies and does not warrant pesticide use, but keep an eye out for lanternflies around your tree.

As you care for your new tree, we hope you see beautiful growth and integration into your yard! If you have any questions or concerns regarding the health of your tree, please reach out to us at [email protected]
