Massachusetts Certified Arborist Designation (MCA): This is perhaps one of the most difficult designations to achieve within the Green Industry. Even industry veterans are prone to fail this exam, due to its extremely rigorous examination of the Arborist candidate's knowledge of all aspects of tree care. In a period of 55 years, less than 900 professionals have earned the right to use the designation of MCA after their name, which is used like other designations, i.e. RN, LPN, PhD, to indicated professional standing.


Massachusetts Certified Arborists must not only show proficiency in all aspects of tree care, but must also maintain their certification on an annual basis, obtaining 5 re-certification credits every year. A college course in Arboriculture, for example, only merits a single re-certification credit.


Thus, the name MCA is more than a title; it is a symbol of dedication and commitment to the best practices and the most recent advances in the field of arboriculture.

The Massachusetts Arborists Association (MAA) is an organization of tree care professionals, largely comprised of arborists and industry allies from Massachusetts, although there are members from other states as well. The objective of the Massachusetts Arborists Association is to further the practice of professional tree care within Massachusetts and also across the nation. Members of the Mass Arborists Association pledge to promote the best practices in arboriculture on a daily basis, upholding prefessional standards and seeking to educate customers and inform them appropriately about issues relating to tree care. With offices in the Boston area, they maintain a commitment to advancing the interests of tree services and their clients.

The Massachusetts Association of Landscape Professionals (MALP) is a non-profit trade organization that seeks to advance the Green Industry in Massachusetts. Its membership includes landscape management contractors, design/build installation contractors, lawn care professionals and other allied green industry professionals. For more than 30 years, MLP has elevated the professional standards and business success of its members through education, certification, advocacy and networking.

The Coalition for Better Landscaping (CBL) is a union of Green Industry Professionals willing to take action to fight harmful landscape practices that are damaging existing green infrastructure and that will negatively affect yet-to-built landscapes. Some areas of concern for the Coalition include tree planting and pruning practices.
