From the 2005-06 annual:
A “buck deer” is a deer with a hardened antler protruding through the skin. A “spike buck deer” is a BUCK with no antler having a fork or branching point. ALL OTHER DEER ARE ANTLERLESS DEER.
SPECIAL ANTLER RESTRICTIONS:
• In Austin, Bastrop, Brazoria, Caldwell, Colorado, DeWitt, Fayette, Fort Bend, Goliad, Gonzales, Guadalupe, Jackson, Karnes, Lavaca, Lee, Matagorda, Victoria, Waller, Washington, Wharton, and Wilson counties, there are special regulations for buck deer. In these counties, the bag limit is two legal bucks, but only ONE may have an inside spread of 13 inches or greater. A legal buck deer is defined as having:
• a hardened antler protruding through the skin AND;
• at least one unbranched antler; OR
• an inside spread measurement between main beams of 13 inches or greater.
• To determine if a buck has an inside spread measurement of at least
13 inches, look at the distance from ear-tip to ear-tip on a buck with ears
in the alert position (see illustration).
• Definition of a point: A point is a projection that extends at least one
inch from the edge of a main beam or another tine. The tip of the main
beam is also a point.
• Does not apply on Level 2 or 3 MLDP properties.
