Things to watch

• Heavily developed. About 65% of the land within a mile is developed. Less room for forage, and more neighbors near the hives.
• Bee crops nearby that are often sprayed. Citrus: grapefruit: insecticides used on about 63% of surveyed US acres (2025); Citrus: lemons: insecticides used on about 75% of surveyed US acres (2025); Citrus: tangerines: insecticides used on about 82% of surveyed US acres (2025). Figures are from USDA's Agricultural Chemical Use Survey, matched by crop type from the crop map. The survey counts any insecticide use in the crop year (not seed treatments) and doesn't say when; ask nearby growers about spray timing.

How San Antonio Heights ranks

Percentiles among 3,000 random land points in each region, scored the same way: land in general, not beekeepers' apiaries.

About 40% of the land here is scored with national averages for its vegetation type rather than measured plant cover, so the wild-plant part of this estimate is rougher than the crop part.

An estimate from public maps (USDA crop maps 2021–2025 averaged, LANDFIRE vegetation), not a survey of the ground. Maps can't see garden plantings, understory density, other beekeepers' hives, or this year's weather. The point is the Census Bureau's published center of San Antonio Heights (34.1564, -117.6587); a yard a mile or two away can differ, so check your own spot.
