Maintaining and adding trees  to commercial sites such as office buildings, factories, warehouses and retail outlets dramatically increases the aesthetics of the curbside exposure to the buildings. It also shows a commitment to the community and environment. It has been shown that having trees around us reduces stress and calms our perception of the environment around us. This can in turn create a more positive work environment or shopping experience. A consulting arborist can help guide you on the journey to having a positive green space.

Our goal is to help you manage your green assets while supporting a healthy environment. A mature, healthy maple tree can offset as much as 4.4 tons of carbon dioxide. Which is approximately the same amount of carbon emissions of driving a compact car for one year.  Just imagine how much your property can do to offset the impacts of climate change while providing a personal oasis?

Larger commercial and estate properties are no problem for Green Bird Horticultural Ltd. With our extensive knowledge in arboriculture and horticulture, we can create a Green Asset Management Plan specifically designed for your property’s needs and your goals.

We look forward to working with you.  Tree period
