Fullerton Arboretum Achieves Reaccreditation at Highest Level

Share This:

In October 2017, Fullerton Arboretum received its first accreditation as a Level IV arboretum. This is the highest level awarded by ArbNet, an organization that recognizes arboreta from around the globe at various levels of development, capacity, and professionalism.

An ArbNet accreditation is good for five years, and it was recently announced that Fullerton Arboretum has been reaccredited at Level IV! It is one of three arboreta in California and one of 39 arboreta in the world to achieve this level.

The accreditation is more than just a number; it’s a mark of the hard work and dedication that has been put into this 26-acre botanical garden through the years. Miguel Macias, the Education Program Manager at Fullerton Arboretum, says “This proves how much the Fullerton Arboretum has accomplished by following industry standards, development, capacity and professionalism in the public garden world.”

Following this exciting achievement, what is next? Miguel says they are working on an additional accreditation. “We are looking forward to being accredited by the Botanical Garden Conservation International (BGCI), which is another international organization that focuses on plant conservation.”
