Urban Wild Edibles Database

Get a field guide specific to your region—not a generic national book. Cross-reference with online databases like iNaturalist or your state university extension. Spend 30 minutes learning the 3 deadliest plants in your area first. You need to recognize poison hemlock, pokeweed berries, and whatever's locally dangerous before you start looking for food.

Pick a neighborhood zone (your local park, a 5-block radius, an undeveloped lot) and walk it slowly. Look for common edibles: dandelions, plantain, chickweed, clover, purslane. When you find a candidate plant, photograph it from multiple angles—whole plant, close-up of leaves, stem structure, underside of leaves, any flowers or seeds.

Use PlantNet or Picture This for initial ID, but verify with physical field guides. Check at least 3 identifying characteristics. For each plant you confirm as edible, note: exact location (GPS coordinates), date, growth stage, surrounding environment, proximity to roads or treated areas. Mark contamination zones—anything within 50 feet of busy roads, treated lawns, or dog-walking hotspots.

Create database entries in your chosen system (digital spreadsheet, Notion, or specialized foraging apps). Include: common name, scientific name, location coordinates, photos, harvest season, edible parts, look-alike warnings, contamination assessment, quantity assessment (one plant vs. large patch), and your personal harvest dates. Add tasting notes when you try something—'lemony', 'bitter', 'mucilaginous' matter for future reference.

Return to logged plants weekly during growing season. Document changes—when flowers appear, when seeds set, when leaves get tough. Wood sorrel in April tastes completely different than August. Your database should track these patterns. After 4-6 weeks, you'll have seasonal data that makes you a better forager than someone with just a field guide.

Expand your database by adding 2-3 new species monthly. Focus on positive ID before tasting anything. Join a local foraging group's plant walk (search Meetup or Facebook) to verify your identifications with experienced foragers. Update contamination notes if you see lawn treatment flags or new construction.
