Canadian Hemlock Viburnum dentatum Chicago Luster Viburnum Table 3 Approximate costs of irrigation, pump, and winterizing equipment and installation as compared to a treatment and storage pond or a holding tank with regular pumping over the winter.
We employed an integrative approach to reconstruct the postsettlement structural and compositional development of four mature Tsuga canadensis
stands in central Massachusetts, using stand-level pollen stratigraphies, tree ring chronologies, and historical records.
The seeds and seedlings of the hemlock, Tsuga canadensis
on the TS plot and Acer rubrum on the MLBS plot were the only species, other than A.
The pollen record from Graham Lake indicates Tsuga canadensis
first increased in abundance at [approximately]7500 yr BP to become one of the forest dominants, forming mixed forest along with P.

The intensity of browsing has prevented the establishment of a 'seedling bank' of such rolerants as Acer saccharum and Tsuga canadensis
, which could dominate regeneration upon canopy destruction (Runkle 1985).
The ecological significance of Tsuga Canadensis
Three forest cover types were distinguished: (1) deciduous forest - sites at which deciduous trees comprise over 70% of the overstory basal area; (2) coniferous forest - sites at which coniferous trees, primarily Tsuga canadensis
, comprise over 70% of the overstory basal area; and (3) mixed forest - sites at which the overstory is comprised of both deciduous and coniferous species with similar basal area.
