I would say nutrition isnt so much a factor...Most of our wmas are similar to each other...palmetto flats,piney woods,oaks,bayheads n river bottoms...and all of em have big bucks...The reason we dont see em often is that mature bucks on pressured public land are very smart...over time they learn to avoid hunters...prime example the 9 point I shot this past season I tracked off a mile and a half rubline thru palmettos n bayheads...I blanketed the area with cameras for a month...NO big buck pics but could see large buck tracks crossin the game trails all in there...I hunted these game trails a couple times but no big buck...I noticed a small bayhead a couple hundred yards southwest that was purty thick...decided to check it out n it was scraped n rubbed up...knew i found the core...next mornin slipped in n dropped that buck...long story short...these pressured mature bucks can reside in very small thick areas during daylight hours...This is the reason we dont see many big bucks...they are out smartin us lol
