Wally is known by many for his excellent programs on collecting bromeliads in Central and South America and his expertise on the species. Also, he volunteered many hours working at Marie Selby Botanical Gardens where he gave workshops, assisted Harry Luther in the greenhouses or wherever he was needed, and was an intricate part of the Sarasota Bromeliad Society.
Wally was also very highly respected by his church family as well as in his neighborhood. He was one of a kind and left a great legacy for all his family and friends.
The BSI has awarded him with the horticulture Award of Excellence and has created "The Wally Berg Award of Excellence" to be presented at future World Bromeliad Conferences to a worthy recipient.
