The Gifted Tree plants a lot of trees in memory. In fact, since we started doing so in Ireland in 2013, we have planted over 150,000 trees in United States National Forests and in projects around the world. Most people think that we plant trees to help reforest areas after devastating forest fires. And we do so, especially in planting projects out west and in Florida. But a number of planting projects’ goals are to help improve water quality in areas in the vicinity of the planting projects as well as further down stream.
Before zeroing in on how planting trees can improve water quality, it is important to understand nature’s water flow. When it rains or snow melts, water runoff is created. The water moves over the surface of the land and is absorbed into the ground or continues on its natural course into streams, rivers, lakes, and other water tributaries. Runoff can occur on natural surfaces like soil, grass, or forest floors, as well as on impermeable surfaces like roads, rooftops, and sidewalks. Runoff can carry pollutants such as chemicals, sediments, and debris into nearby water bodies, which has a profound impact on water quality. Managing water runoff is important in urban planning, agriculture, and environmental protection to prevent issues like flooding, soil erosion, and contamination of water sources.
The planting of trees in the right location can help manage the runoff of this water, acting as a natural filter. Over time, tree loss has harmed water sources by not filtering the pollutants and sentiments that can flow into water sources after rain and snow melt. Trees can help absorb this runoff and thus play a crucial role in the water flow ecosystem.
How Do Trees Help Manage Water Runoff?
1. Canopy Interception
Trees intercept rainfall with their leaves and branches, slowing down the rate at which water reaches the ground. This reduces the volume of runoff and allows more time for water to infiltrate the soil rather than flowing directly into storm drains or water bodies.
2. Root Absorption and Infiltration
Tree roots absorb water from the soil, helping to reduce the amount of water that becomes runoff. Roots also help improve soil structure, creating channels for water to infiltrate deeper into the ground. This enhances groundwater recharge and decreases surface runoff.
3. Soil Stabilization
Tree roots bind the soil together, reducing erosion caused by runoff. By stabilizing the soil, trees prevent sediments from being washed away into nearby water bodies, which helps maintain water quality and reduce sedimentation in rivers and lakes.
4. Evapotranspiration
Trees release water back into the atmosphere through a process called evapotranspiration. This helps reduce the overall amount of water that becomes runoff, contributing to a balanced water cycle.
5. Shading and Cooling
Trees provide shade, reducing soil temperature and evaporation rates. Cooler soil temperatures and reduced evaporation mean more water is available to infiltrate the ground, decreasing runoff.
6. Reducing Impermeable Surface Impact
In urban areas, trees planted along streets and in parks can help reduce the impact of impermeable surfaces (like concrete and asphalt) by absorbing water and preventing excess runoff from these hard surfaces.
By managing water runoff, trees help mitigate flooding, reduce pollution in waterways, and promote healthier ecosystems.
The Gifted Tree’s Water Improvement Projects
The Gifted Tree has a number of planting projects around the country whose stated goal is to help stabilize soil around streams and thus help improve water quality. Several of these projects are listed below:
Oregon
This planting project is along the Willamette River Valley south of Portland. Our memorial and celebration trees filter excess sediment, nutrients and toxins before they enter this vital water source. The trees also provide shade for streams, making them healthy environments for fish, such as Oregon’s rainbow trout, steelhead and Chinook salmon.
Pennsylvania
This The Gift Tree planting project is along the Susquehanna River, Pennsylvania and it exists to protect the Chesapeake Bay watershed. The collective goal of the planting project is to buffer the approximately 6,250 miles of Pennsylvania streams within the watershed, the main one being the Susquehanna River which delivers half of the freshwater entering the Bay. As a result, drinking water sources are cleansed and native water habitat is improved which makes the fish and other wildlife in the area very happy.
Maryland
This Gifted Tree planting project is along the Chesapeake Bay watershed in Garrett, Allegany, and Washington Counties, Maryland. The overall goal of the project is similar to our other water improvement projects: through the planting of trees, improve the water quality of the stream water flowing into the Chesapeake Bay.
These are three examples of The Gifted Tree’s planting project whose main goal in planting memorial trees and celebration trees is to improve water quality for millions of people who reside in their watershed districts. Tree root systems play an amazing filtering role in the soil and these new plantings will help reduce the levels of nitrogen, phosphorous, and sediment that exist in the Chesapeake Bay, Willamette River, and other water sources. These are problems that affect many natural areas in the face of intensive agricultural practices and increasing human development. The reforestation effort will also aid in erosion control, flood mitigation and storm water management, and help promote population rebounds of vulnerable and threatened wildlife. Be sure to contact us with any questions you might have. Or better yet, plant memorial trees or celebration trees to show a loved one or a friend that you care, as well as to start helping improve water quality today.
