Personal Enrichment: 

The Dendrological Society affords members the opportunity to go on outings into the veld under the leadership of knowledgeable dendrologists and to spend time with other people sharing the same interest in nature. These outings are mainly focussed on indigenous species but knowledge can also be gained about trees and the plant kingdom in general. Snippets of information can be gained from all people participating in the outing, although many may not yet have an extensive knowledge of the topics at hand. Tips are also given to practice or promote tree identification as a hobby.

Members gain satisfaction from their participation in and promotion of tree knowledge and conservation issues. People get to know their environment and opportunities are created to come into contact with many tourist attractions. Personal enrichment is gained by accumulating knowledge and by making contact with the wonders of nature. By being so close to nature an added benefit is spiritual enrichment.

Members are also given the opportunity on a tertiary level to attend courses and to qualify in primary dendrology.

Financial Benefits: 

Members enjoy discounts on some publications at selected book shops and course fees.

Conservation of Trees: 

The Society acts as a mouthpiece on behalf of members (and trees) in communications with authorities regarding the promotion of tree issues and the conservation of tree species.

Social Occasions: 

Outings are social events bringing together people within a particular area. Friendships are formed with people throughout the country. People sharing the same interests are able to enjoy pleasant company and have meaningful conversations.
