Reducing Deer Browse Damage, Natural Resources Conservation Service, 2009
Some behaviors deer exhibit that may be useful in developing a deterrent plan.
Learns to tolerate:
- bad taste or smell,
- colored strobe lights,
- sirens and loud noises;
- Jumps high (up to 12 feet with sufficient motivation) or far (up to 30 feet with sufficient motivation), but not both at same time;
- Crawls through openings as small as 7.5 inches;
- More likely to jump fences in woodlands than in open areas;
- Learns to remove bud caps and netting protecting terminal buds;
- Follows customary paths to known food sources;
- Tests for weaknesses in any and all barriers, repeatedly;
- Nibbles young stems emerging from tube protectors and chemical repellents.
Well, this tells us how deer behave. Going to be tough to come up with real deterrents.
