Very well, but unlike deciduous stuff they have to be done in Spring to Autumn because doing them in Winter there is a chance of death. The lignotuber of some species would lend itself to better coppice. Pollarding sawlogs on ladders is relatively common in agricultural settings like Syntropic and others.
If you are cutting them as small as possible, I’d assume the tree would go backwards in health. You need lots of leaf between cuts to keep the health up. These trees were planted at the same time, a percentage got the second cut, some were on their first and the main pictured one was pushing a little too big.
I’m no worldwide expert but I have done a lot of pollards and if I’m cutting for biomass, I don’t let them exceed 40mm, and will cut annually if they reach 20-40mm within that year. If the majority of shoots are below 20mm, then 2 or 3 years. Juvenile trees often need annual cuts before setting in into 2-3 year cycles. Mulberry is an exception, on wet years they need annual cuts before bud burst.
The Oak pollards of old for shipbuilding, would have had very large cuts on long cycles. I think they cycle mosaic coupes because you need sun to hit the shoots or they die. I think with our humid Summers, too big is a risk for a lot of species but Eucalyptus with their resistant timber could go reasonably big (evidenced by old tree loppings all over).
