What is an Arborist?
An arborist is someone who, through education and training is qualified to practice arboriculture. Arboriculture is the application of standards and techniques developed to improve the condition of shade, ornamental and fruit trees. Practices include pruning, cabling, bracing, fertilization, aeration and the control of insects and diseases. The arborist is knowledgeable about the typical growth habits and preferred site location and conditions of healthy trees and is able to diagnose problems from the obvious insect infestation to the less obvious environmental stresses such as changes in soil grade or drought that may affect tree health.
An arborist license, issued by the Department of Energy and Environmental Protection, is required to practice arboriculture for hire in The State of Connecticut.

(b) There shall be in the Department of Environmental Protection a State Tree Protection Examining Board which shall consist of the plant pathologist and forester of the Connecticut Agricultural Experiment Station, who shall serve as ex-officio members, and five electors of the state, three of whom shall be public members, and two of whom shall be licensed, practicing arborists to be appointed by the Governor. Any vacancy in the appointed membership of the board shall be filled by the Governor for the unexpired portion of the term.
(c) The board shall have a seal and, in the proceeding in court, a certificate under such seal shall be bona fide evidence of any proceeding or action by or before the board stated in such certificate. A majority of members acting as a board shall constitute a quorum for the transaction of business.

Sec 2. Section 23-61b:
(a) No person shall advertise, solicit or contract to do arboriculture within this state at any time without a license issued in accordance with the provisions of this section, except that any person may improve or protect any tree on his own premises or on the property of his employer without securing such a license provided such activity does not violate the provisions of chapter 441, subsection (a) of section 23-61(a), this section or section 23-61d. Application for such license shall be made to the Commissioner of Environmental Protection and shall contain such information regarding the applicant's qualifications and proposed operations and other relevant matters as the Commissioner may require and shall be accompanied by a fee of twenty-five dollars which shall not be returnable.
(b) The Commissioner shall require the applicant to show upon examination that he possesses adequate knowledge concerning the proper methods of arboriculture and the dangers involved and the precautions to be taken in connection with these operations, together with knowledge concerning the proper use and application of pesticides and the danger involved and the precautions to be taken in connection with their application. If the applicant is other than an individual, the applicant shall designate an officer, member or technician of the organization to take the examination, which designee shall be subject to the approval of the Commissioner except that any person who uses pesticides in arboriculture shall be licensed to do arboriculture or shall be a licensed commercial applicator under chapter 441.

(d) Each licensee shall pay a license renewal fee of one hundred and fifty dollars for each renewal. All examination and license renewal fees shall be deposited as provided in section 4-32, as amended, and any expenses incurred by the Commissioner in making examinations, issuing certificates, inspecting tree work or performing any duties of the board shall be charged against appropriations of the General Fund.
(e) Each licensee shall maintain and, upon request, furnish such records concerning licensed activities as the Commissioner may require.
(f) The Commissioner may suspend for not more than ten days and, after notice and hearing as provided in any regulations established by the Commissioner, he may suspend for additional periods, or he may revoke, any license issued under this section if he finds that the licensee is no longer qualified or has violated any provision of sections 23-61a to 23-61d, inclusive, as amended by this act, or any regulation adopted thereunder.
(g) The Commissioner of Environmental Protection, in consultation with the board, shall establish standards for examining applicants and reexamining applicators with respect to the proper use and application of pesticides and agricultural methods.
