Can someone identify these Australian trees?

There's a reason why they are native to a small area along the coast. Plant them inland where the climate is dryer and hotter and they have short lives and are subject to being attacked by borers and prone to diseases. Stressed by being planted in a less than ideal environment, they lose their ability to fend off some diseases and insects. They usually do quite well when young and grow quickly. It's usually as they age you see the downside. Perhaps NZ and a few other places has the ideal climate for them to thrive. Their natural range in CA is becoming smaller.

They are grown extensively in plantations around the world for timber production, including some quite hot climates.

Trees in NZ are harvested around 20-25 years and trees are already 100ft or higher and 2-3 ft wide. Plenty of the trees have already succumbed to various conditions or weather related causes by then. They're certainly not a tree much used outside of timber production.

That makes perfect sense. Thank you for sharing.

I read somewhere, that it is a tree with one of the smallest natural ranges, yet is now one of the most widespread and planted trees in the world.

I planted around 20000 of them last winter - they grow like flippin weeds.

It's a good bet that they are P radiata, or so I was told (as they were introduced here in the 1800s).

Can you identify these shrubby light green trees in front of them (I know the photo clarity is not the best):

You need more closeup. It could be anything.
