✦ Bees specialist-bee host · 8 bee visitors

Specialist native bees depend on it.

Some native bees are pollen specialists (oligolectic) — they raise young only on pollen from particular plant genera. Vachellia is a recorded specialist-bee host, so losing it can mean losing the bee that relies on it.
