The managementprooedures reco~nded are based on sound ecological<br />

,t-1rinciples as revealed by the published literature (7,,8,,9) a.nd are in actual<br />

commercial praotioe by the more progressive utilities and state Forestry<br />

Depar:t~nts (lO/ll). In the oommunities represented, three slightly different,management<br />

procedures are required to produce a,dosivable vegetation<br />

pattern.<br />

(1) Central part of rgght-of-W!\y'.t directly under! the wires. All tallgrowing<br />

trees whio might eventually grow or fall into the lines<br />

are removed. Low-growing shrubs and seattered taller shrubs are<br />

preserved, In general, shrubs tha.t eventually grow over 3 1 in<br />

height should be removed if they occur in large colonies which<br />

spread over the ground for distances of 25 t or more. A trail 8­<br />

10 1 in width, prefera.bly oomposed of grasses, should be maintained<br />

in order to permit access for inspection and repair. A similar<br />

pattern is reoommendodaround the bases of poles and towers.<br />

(2) The sides of the right-of-waX, between the outermost wires and<br />

the forest edge. TaIl-growing trees which might eventually grow<br />

or fall into the lines are removed. Therefore, along the sides<br />

all shrubs and low-growing trees are preserved to form the densest<br />

possible cover so as to resist future invasion by trees.<br />

(3) Forest e e adjacent to the right-of-w .. Here tall-growing trees<br />

are remove e ore they reach the ed.gh of the wires. This<br />

eliminates the danger of trees falling into the wires and avoids<br />

costly cutting operations 111the future.<br />

The pattern created is a V or valley-like effect in which only low<br />

vegetation persists in the center of the right-of-way with taller growth<br />

along the edges on both sides.<br />

Nature of the Vegetation<br />

'Vilhenestablished in 1953, two distinct cover types--shrubland and<br />

sprout-hardwoods--were recognized. The former, covering one-third of the<br />

line, was dominated by dense thickets of greenbrier and sawbrier (Smilax<br />

rotundifolia, §.. slauca) and sumac (~ copallina) interspersed with other<br />

shrubs and tree growth. The more commontrees included red maple (AceI'<br />

rubrum) and black cherry (Prunus serotina). Herbaceous cover was limited<br />

to occasional openings. In the sprout-hardwoods type an upland and lowland<br />

phase was recognized. In the former, various oaks--white, scarlet, red and<br />

black (Querous alba, 9.. cocoinea, 9,. rubra, 9,. velutina) along with black<br />

birch (Betula len:ta) we~e dominant, while in the wetter areas, red maple was<br />

most common. Other trees on the line included hickory (Carya sPPJ, aspen<br />

(Populus spp), gray birch (Betula .populifolia), tulip (Liriodendron tulipifera),<br />

sassafras (s,assafras albidum), wh:te ash (FlllQd.nusamericana). In<br />

some areas shrub growth was soattered; in other sections it formed continuous<br />

cover.<br />

In surveying the easement, over forty species of desirable shrubs and<br />

low-growing trees were. found. Amongthose shrubs most frequently encountel'en __<br />

- which do not grow over 3' in height and are permissible w~ver they occur .<br />

on the right-oi-way, are sweet fern (Comptonia peregrina). sheep lanrel
