Planning a Structural and Sustainable Walking Park: Fast-Growing Tree Species
When designing a walking park, particularly one with a set area of 17 meters by 400 meters, the choice of tree species can significantly impact both the aesthetics and the sustainability of the space. Fast-growing tree species, especially conifers, are preferred due to their rapid establishment and visual impact. This article explores several suitable species, including Arborvitae and Lombardy poplar, and provides practical guidelines for their planting and spacing.
The Role of Fast-Growing Conifers
Conifers are among the fastest-growing tree species, offering rapid visual results that can enhance a walking park both quickly and sustainably. One popular choice is the Leyland Cypress, known for its extremely fast growth rate, although it typically only reaches 40 feet (12 meters) in height. However, as the article notes, newer and older species are increasingly being chosen for their unique characteristics and environmental benefits.
Green Giant Arborvitae Trees: A General Rule of Thumb
Planting Green Giant Arborvitae trees at a distance of 6-8 feet apart can provide the best performance in terms of growth and coverage. This spacing ensures that the trees have enough room to grow while also providing a lush, well-defined privacy screen. The rule of thumb is particularly useful for those engaged in DIY gardening or managing small to medium-sized parks.
Other Fast-Growing Broadleaf Species
Besides conifers, broadleaf species can also be an excellent choice for fast growth and structural integrity. Here are a few suggestions:
Lombardy Poplar
Lombardy poplar is a quick-growing deciduous tree that can add an impressive visual impact to any walking park. Its straight, slender trunks and fast growth make it ideal for creating an imposing, linear feature that guides visitors through the park. Lombardy poplar is also effective in forming a protective screen for slower-growing trees.
Paulownia tomentosa
Paulownia tomentosa, often called empress tree, is another rapid-growing broadleaf species that can significantly transform a park's landscape. It can be an excellent choice for areas with good soil conditions. However, it is important to note that its fast growth rate might require more frequent pruning to maintain a desired shape.
Populus nigra (-black poplar or Lombardy poplar)
This species is often referred to as the black poplar due to its dark heartwood and is known for its impressive height and fast growth. It is a versatile tree that can be used in a variety of settings within a walking park.
London Plane Tree (Platanus x acerifolia)
The London plane tree is a robust and fast-growing deciduous tree that can tolerate a wide range of soil conditions. It is an ideal choice for areas with either good or poor soil. Its unique, mottled bark adds an aesthetic appeal to the park, and its rapid growth can help in shaping the park's structural framework.
Italian Cypress (Cupressus sempervirens)
For those seeking a more conifer-like fast-growing tree, the Italian Cypress is an excellent choice. It has a medium to fast growth rate and can thrive in both good and poor soil conditions. This tree's tall, narrow form makes it suitable for creating vertical accents and boundaries within the walking park.
Additional Benefits of Fast-Growing Tree Species
Planting fast-growing tree species can have additional benefits beyond aesthetics and structural integrity. For instance:
Emission Reduction
Fast-growing trees, like the Paulownia, are known for their ability to consume large amounts of CO2. This makes them valuable in the fight against climate change and air pollution. Incorporating such species into a walking park can contribute to a greener and more sustainable environment.
Building Wood
The wood from some fast-growing species, like certain paulownias, is strong and durable, making it suitable for various building applications. Harvesting this wood can provide additional value to the park and its maintenance practices.
By choosing the right fast-growing tree species, park planners and managers can ensure that their walking park not only looks impressive but also supports sustainability and environmental health.
