会员们:
在树艺这个行业里,从业人员由主理研究、设计、监督、执行、攀爬、行政、顾问等等都有,而当中最难取得证照的,莫过於 “顾问树艺师” 这个名衔了。 要成为一个 “顾问树艺师”,并不能自封自擂,必须要加入有国际地位的组织里面,成为其专业会员,再取得其专业资格,才能成事。 世界上只有几个 “顾问树艺师”学会,每一个招收专业会员的条件都非常苛刻,而当中最大和最有历史的,要首推 “美洲顾问树艺师学会” (American Society of Consulting Arborists, ASCA, www.asca-consultants.org ) 了。
ASCA 是在 1960 年代末,由当时北美洲一群天天在提供树艺顾问服务的执业树艺师所发起的。 鑑於他们发现树艺顾问行业与其他的搞树木研究、种养和修剪,在工种和处理问题时有所不同,而作为一个“顾问树艺师”,在现场勘察、证物分析、编写报告和庭上作供的时候,所需要的专业知识和研究理论是有别於一般的树艺从业员。 所以这群人特别组织起 ASCA,亦创建了一个叫做 Registered Consulting Arborist, 简称 RCA 的专业牌照,来把“顾问树艺师”从众多的树艺从业员当中昇华出来,鹤立鸡群。
RCA 牌照有别於其他树艺牌照,可说是金字塔的顶端,高山群的峰峦,是非常难考的一种牌照。 此牌照也可能是自有树艺牌照发行以来,其中最早的一个,首发於1960年末。 与 RCA 比较, “国际树木学会” 的 “注册树艺师” 牌照是在1994年才开始发行。 而其“资深树艺师” 牌照就更晚,它的美国商标注册是在2003年。
当全世界已拥有超过 25,000 个 “注册树艺师” 和近千个 “资深树艺师” 的时候,尚在人世的 RCA , 只有大概 250 个。 从 1960 年末至 2014 年所考获 RCA 牌照的人,只有 600 个左右,也就等如是每年能够考到 RCA 的,只有 10 人左右,它是世界上公认的最困难的专业考试之一,合格率一般不到百分之十 ! 在本会会长报考 RCA 的那一年,考生一共有 56 人,当中过半都是北美洲的大学教授、博士,资深树艺师等等,当中也不乏知名人士。 但在一年後公佈考试结果时,只有四人能够考到,惊心动魄 !
RCA 是目前树艺行业里面最高的专业资格,全亚洲到今天为止,只有本会会长欧永森一人持有;全世界的 “顾问树艺师” 当中,也只是他一人是华人,太少了。
本会寄望有志在树艺行业登上极峰之士,早日起航,报名参考 RCA,再为中华民族争光 !
谨此致意!

Dear Station Members,
Consulting Arborists are authoritative experts on trees, consulting property owners, municipalities, attorneys, insurance professionals and others on tree disease, placement, preservation and dispute resolution in addition to providing consulting and expert testimony in the legal, insurance and environmental arenas. The role of the Consulting Arborist is to bring a comprehensive, objective viewpoint to the diagnosis, appraisal and evaluation of arboricultural issues.
Consulting Arborists are also known as the preeminent authorities on matters related to trees—ensuring the safety, health, and preservation, of trees in our natural surroundings. They are tree experts who advise in the most challenging situations. Their experience in the science and practice of arboriculture, along with their practical, ethical and objective role of consultant, is key to two distinct groups of people:
- Industry professionals, such as law firms, insurance companies, utilities, land developers, architects and municipalities who need:
- Reports on trees and — plants in general
- Expert testimony in court
- Evaluation of the environmental impact of land development
- Consultation on tree preservation
- Expertise for land planning
- Education about the preservation of trees
- Forensic investigation into tree issues
- Consultation on care and maintenance
- Assessment of risks and hazards
- Landowners, such as homeowners, real estate owners, developers and others who need:
- Knowledge of tree care, preservation and maintenance
- Expertise about tree and plant selection and planting
- Assessment and identification of tree risks and hazards
- Advice on tree preservation
- Appraisal of trees
- Investigation into tree disputes and negligence
- Inspection of plant material and tree issues
In CAA, we hold the Registered Consulting Arborist (RCA) to be the highest ranking in the Arborist Profession. We regard them to be the creme de la creme.
For anyone wanting to become an RCA, please refer to http://www.asca-consultants.org/pdf/d_asca_rca.pdf . We recommend our members to join & try, to build up our profession in the China Region.
best regards,
