Not really DB. Tropical savannah across Australia and Southern Africa has no large grazing animals. Termite colonies fill that niche, and we build to give them as little encouragement as possible. The original overland telegraph was built on timber poles. The lesson was quickly learned and iron posts with efficient insulators became the rage.

As a historical aside, the aboriginals learned to throw stones at the glass insulators, garnering a ready supply of very sharp and durable spear points and tools.
