Splinter ,
I havent heard of this happening but I really would'nt be suprised if it did . There really has'nt been a good or for that fact a decent market for hemlock in NH for the past 5 years atleast . We use to ship it to a mill in Canada mainly just good sized butt logs and the rest would go as pulp , other than that it would all go thru our chipper and sent to the Shiller Station for power .
With they way the market is these days Hemlock is now basically a biomass fuel , for the most part fell and chip it all , Im sure this isnt what you want to hear but for the past 3 yrs or so this is almost all we do with hemlock woodlots , if the lot has other timber on it which most do , IE: Pine , Mixed hardwood we would go in and thin the stand of all the hemlock.Lets light back onto the forest floor and promotes regen.
