There is growing concern as forest land outside of conservation areas is steadily decreasing. There has been a disturbing reduction in primary forests of 40 million hectares in the last decade. The total area of forest within protected areas has increased by 94 million hectares in the past two decades and now accounts for 13% of the total of forests globally.
Tree healthcare for humans
Trees are well known for providing oxygen as a result of their photosynthesis process. It is in fact the carbon dioxide (CO2) that is removed during this process therefore helping to mitigate the negative effects of burning fossil fuels ie. CO2 production. The benefits to the world of this process make the existence and importance of the Amazon rainforest especially significant.
Trees benefit cities too
Not only are trees a beautiful addition to any city, they also serve a practical purpose by absorbing pollutants. Their presence makes a city appear more vibrant and more friendly. For example, San Francisco is home to 105,000 trees. Tree planting should be kept in pace with tree mortality and tree removal. A tree management plan is essential to ensure sustainability.
Tree management for woodland
Trees should be checked for health and also for the merchantability of the trees. When areas of the woodland require thinning out it is useful to produce a product that has a commercial value. This way waste management has been prioritized and has turned a Liability into an Asset. The harvested wood/logs can be considered an asset and can be sold as fuel. Always ensure trees are removed when over-crowding is an issue to allow for tree growth of the remaining trees. The woodland is sustainable by including sufficient planting of new trees.
Maintaining the urban trees
Your arborist can advise you of local procedures and the law regarding your trees which if not properly managed can become a legal liability. Some types of trees do not take well to heavy pruning, for example the Southern Live Oak is best not located in restricted areas where heavy pruning to clear avenues may be required. It is better to grow it in a larger landscaped area where it can grow with minimal pruning. They often reach 60 to 80 feet in height with a 60 to 100 foot spread.
The branches of Live Oak tend to droop as they grow so some careful pruning will be necessary especially as this type of growth can be a problem for vehicular or pedestrian clearance beneath. Many trees are not permitted to be removed without obtaining a tree removal permit first. This is good as it provides some protection for the trees.
Other tree varieties to grow with sustainability
The beautiful red maple is a great yard tree being very tolerant and is able to grow in nearly any conditions but especially in acid to neutral soils. Plant away from paths etc as the roots can raise sidewalks if too close. A good layer of organic mulch should be placed around the roots to feed and help retain moisture.
Another commonly found tree in the US is the Loblolly Pine. When found in plantations it provides the perfect habitat for wildlife such as deer, squirrels making it a very sustainable choice. Being a faster growing tree it requires more regular pruning.
Enjoy our future with sustainability for trees
Sustainability ensures we leave the world in a good state for future generations to enjoy, whilst still meeting the needs of the current population. Keep your trees maintained moving forward and always pay attention to the type of tree and manage accordingly. This way you can enjoy the many beautiful trees around you.
