laboratory by a public or private college or university, or (3) to protect federally listed endangered species under a federal permit or for conservation or
restitution projects under certain federal and state statutes. The land must also be used for agriculture to the degree of intensity generally accepted in the

You must complete this application in full and le it with the chief appraiser before May 1 of the year you are applying for agricultural appraisal. To be
