DeckH, our property Owners Assoc voted 1 1/2 years ago to remove the cattle from the ranch due to over grazing issues. Many PO are applying for the Wildlife Valuation. You get a 2 year rest before you either have to return the cattle, or submit a wildlife management plan.
My wife and I decided to just pay the taxes since it is based on the appraised value, which is about 1/2 of what we pay for the land.
Scatterbrain, you can find and download the forms at the Texas Parks and Wildlife web site. Basically there are 7 areas of wildlife management, and you select 3 of those that you will practice. Complete the forms clearly documenting what you are doing (supplemental feeding, clearing of cedar, houses for bats, or song bird etc..., maintain excellent records that show what you did, money you spent, ect.. Each year you collect the records and turn them in, with the approved plan lasting 3 years.
Each county has folks that read these applications and either approve or disapprove them. Many are disapproved because the forms turned in by the land owner is incomplete, not clearly worded to explain what is being done. Some ag agents that read these can be picky. If you choose supplemental feeding, it can be costly. It isn't just running a corn feeder, and some applications will be rejected for that reason. A co-worker who is feeding spends more on protein and corn than he would if he just paid the full taxes. It all depends on your particular property and the areas of management you choose.
The Pks & Wildlife Dept has biologists that will survey your property and offer assistance, but it is up to the land owner to complete and submit the forms for approval.
AEA, welcome to the forum.
