Forestry Benefits

Protects against deer, elk and moose damage.

Forests in America

With unprecedented challenges from major threats such as drought and wildfire, successful regeneration is key to sustaining, healthy and resilient forests of the future. In many parts of North America, increased populations of deer resulting from favorable habitat and reduced predation that is associated with human development, are having a severe impact on regenerating forests.

In many parts of North America, an overabundance of deer (>50 animals per acre), are severely limiting the natural regeneration of the forest understory. Drastic measures are being used to ensure successful regeneration, such as organized mass hunts, or obstructive fencing.

TRICO® PRO is an alternative for deterring browsing by deer, elk and moose.

Tom Fetzer, Fetzer’s Tree Farm. New York State

Nursery Trees
