Hello,
I was wondering if you could id these particular trees. While I live in
Uruguay, those trees are emphatically not native to our country.

They were a windbreak in our ranch home, and I remember fondly playing in their shadow when I was a child - 40 years ago.

The house was neglected, and the trees are falling down one by one.
I'd really like to replace them, but do not know exactly which species
they are. I think they are cypresses, but not an expert.

The last picture, with my backpack against the trunk gives a rough
ide of their overall size. These photos were taken in our early autumn
(southern hemisphere), zone 9.

Can I save seeds from them? Are there any particular guides for their care?
