Jenny, Do you know anything of the history of the hemlock groves? It looks like in your first historical photo from 100 years ago, (1 of 12) that most of the hemlocks in the image are fairly young - judging from size and form. Was the area logged first and these were regrowth from timbering in the early to mid 1800's? They are cutting down some of the larger dead hemlocks as you said from the yellow marking tape (4 of 12) , are there any cut stumps from which you could get any ring counts? I am curious about the age of the hemlocks in the stand (even if they are now dead.) looking at the ITRDB I don't see any series of dates from hemlocks there in the Bronx ( http://hurricane.ncdc.noaa.gov/pls/paleo/fm_createpages.treering ).
