About
Your wildlife valuation is worth protecting. Don't let paperwork be the reason you lose it.
1-D-1 Companion is built specifically for Texas landowners who manage wildlife under the 1-D-1 Open-Space Appraisal. It helps you document your management activities throughout the year, stay on track with compliance requirements, and generate a complete annual report ready for your County Appraisal District (CAD).
WHAT 1-D-1 COMPANION DOES FOR YOU
Guides you through logging all 7 TPWD-recognized wildlife management activities - with plain-language descriptions of what qualifies
Tracks your annual progress by category so you always know where you stand before the April 30 deadline
Builds your evidence library - date-stamped photos, receipts, and notes organized by activity and property
Generates a county-ready annual report formatted for your CAD - no reformatting, no guesswork
Manages multiple properties across multiple counties from a single account
Works offline in the field - log activities and capture photos without cell service, then sync when you're back in range
BUILT AROUND HOW TEXAS LANDOWNERS ACTUALLY WORK
Most landowners are not sitting at a desk - they're out managing pastures, checking feeders, and running cattle. 1-D-1 Companion is designed for the field. Log a predator trap check from your truck. Attach a photo of your water trough installation on the spot. The app saves your work and syncs it when you're back in range.
Every entry you make builds toward a complete, audit-ready record. If your CAD ever asks questions, you'll have organized, date-stamped documentation to back up every activity.
THE 7 MANAGEMENT CATEGORIES - ALL COVERED
Habitat Control - brush management, prescribed fire, food plots
Erosion Control - terraces, buffer strips, waterway stabilization
Predator Control - trapping, exclusion, removal of threat species
Supplemental Water - tanks, troughs, guzzlers
Supplemental Food - feeders, food plots, mineral stations
