The trees of Collier County, both native and non-native, are protected by the Land Development Code specifically section 4.06.05 J (1) states that Vegetation required by this Code shall only be pruned to promote healthy, uniform, natural growth of the vegetation and shall be in accordance with the current Tree, Shrub, and Other Woody Plant Maintenance - Standard Practices (ANSI A300) of the National Arborist Association. Trees shall not be severely pruned in order to permanently maintain growth at a reduced height or spread. Severely pruned trees shall be replaced by the owner. A plant's growth habit shall be considered in advance of conflicts which might arise (i.e. views, signage, overhead power lines, lighting, circulation, sidewalks, buildings, and similar conflicts). 

Prior to 1991 there were no regulations or standards for the trimming and care of trees. Due to growing concern about the many different practices and standards, a consensus was developed for an official American National Standard that would be accepted and adopted by The American National Standards Institute (ANSI).

ANSI A300 is a publication produced using these standards and serves as the basis of our Landscape maintenance and pruning sections of the Land Development Code. You may order copies of this important handbook at in order to learn more about the proper handling of trees and shrubs.

Pruning is the most common tree maintenance procedure. Although forest trees grow quite well with only nature's pruning, landscape trees require a higher level of care to maintain their safety and aesthetics. Learn more about pruning and how it should be done with an understanding of how a tree responds to each cut. Improper pruning can cause damage that will last for the life of the tree, or worse, shorten the tree's life.Please visit the websites below for information and answers to all your questions on trees, palms, plant identification and much more.

The arboriculture industry has developed a variety of progressive pruning standards in recent years, the culmination of which is the current Standard Practices for Tree, Shrub and other Woody Plant Maintenance, published by the American National Standards Institute (ANSI A300-1995). This standard, which industry experts developed by consensus, is intended to replace all previous pruning standards for woody plants.
