Regarding post-construction stream project plantings, boasting "2,300 new trees and thousands of new shrubs" along post-construction Taylor Run, of various species that collectively bear no fidelity to a known natural community let alone the habitat it is replacing, does not constitute a functional natural forest community. Moreover, plantings of “late successional” species outside their appropriate natural habitats typically result in a high mortality of the plantings. (College of William and Mary environmental science professor Doug DeBerry and others have well documented this general failure of post-construction plantings in the scientific literature.)
Clearing mature stream valley forests and replacing them with artificial plantings - both in species makeup and numbers of plants - is an obvious adverse environmental impact that negates any net increase in function or added ecosystem services (improvement) required by the terms and conditions of the Nationwide Permit 27 (NWP).
For these reasons, and others, the "2,300 new trees and thousands of new shrubs" cited for the Taylor Run project will amount to little more than a glitzy "plant dump" and is not an ecological restoration best practice. The stark reality is that anyone over the age of 35 will not see a mature canopy tree along the Taylor Run project footprint again in their lifetime, and certainly nothing like the old-age giants growing there today (estimated to be 180-220 years of age).
It is also unlikely that the stream valley's existing natural features will return - naturally or otherwise - because the living foundation of the habitat, the result of millennia of evolution and complex interactions of organisms and geologic conditions, cannot be replicated - and certainly not by a "forest-in-a-can" method. One cannot plant a forest community, such as the globally and state rare Acidic Seepage Swamp, one can only plant individual trees and other vegetation. Only nature and very long periods of time can produce diverse, ecologically functioning natural communities.
