laws. The impacts <strong>of</strong> logg<strong>in</strong>g on o<strong>the</strong>r functions<br />
and values <strong>of</strong> <strong>the</strong>se wetlands, such as wildlife<br />
habitat, open space, and recreation, must be carefully<br />
considered.<br />
Sociocul tural Values<br />
h d maple swamps are also valuable Lo society<br />
for <strong>the</strong>ir scenic beauty, <strong>the</strong>ir contribution to biotic<br />
diversity, and <strong>the</strong>ir use as recreation and openspace<br />
areas. This collection <strong>of</strong> wetland values has<br />
been variously referred to as socioculturd or heritage<br />
values Wier<strong>in</strong>g 1979) and aes<strong>the</strong>tic, recreational,<br />
and landscape values (Smardon 1988).<br />
The scenic or aes<strong>the</strong>tic value <strong>of</strong> red maple<br />
swamps is most obvious at <strong>the</strong> landscape level<br />
dur<strong>in</strong>g early fall when <strong>the</strong> brilliant ello ow, red, and<br />
orange foliage <strong>of</strong> <strong>the</strong> swamps provides strik<strong>in</strong>g contrast<br />
to <strong>the</strong> upland vegetation whose foliage has not<br />
yet changed from <strong>the</strong> predom<strong>in</strong>antly green shades<br />
<strong>of</strong> summer, Although red maple has <strong>the</strong> greatest<br />
visual affect becausc <strong>of</strong> its predom<strong>in</strong>ance, o<strong>the</strong>r<br />
spies such as black gun and ashes may also be<br />
strik<strong>in</strong>g. Mixed stands <strong>of</strong> hardwoods and conifers<br />
<strong>of</strong>fer a uxsique contrast <strong>in</strong> fall foliage <strong>in</strong> some<br />
swamps. Rad maple swamps border major highways<br />
throughout <strong>the</strong> Nor<strong>the</strong>ast, and each fall <strong>the</strong>se<br />
bright auturml colors are seen daily by thousands<br />
<strong>of</strong> motorist. h d maple swamps clearly are a dis<strong>the</strong>tive<br />
partz <strong>of</strong> <strong>the</strong> scenic beauty that characterizes<br />
this region.<br />
'I'he aes<strong>the</strong>tic value <strong>of</strong> red maple swamps can<br />
be appreciabd on a more subtle level as well: <strong>in</strong><br />
tbe flowers <strong>of</strong> <strong>the</strong> spicebush, which form a yellow<br />
haze <strong>in</strong> <strong>the</strong> ur~derstory <strong>of</strong> hillside seepage swamps<br />
and along upland dra<strong>in</strong>ageways <strong>in</strong> early spr<strong>in</strong>g;<br />
<strong>in</strong> <strong>the</strong> curious hoodlike <strong>in</strong>florescence and broad<br />
green leave8 <strong>of</strong> <strong>the</strong> skunk cabbage; <strong>in</strong> <strong>the</strong> lush<br />
growth <strong>of</strong> c<strong>in</strong>namon ferns <strong>in</strong>terspersed with dark<br />
psals <strong>of</strong> wator, <strong>in</strong>vok<strong>in</strong>g images <strong>of</strong> <strong>the</strong> pri~nevd<br />
forest (Fig. 2.1); <strong>in</strong> <strong>the</strong> fragrant aroma <strong>of</strong> sweet<br />
pepperbush flowers (Fig. 8.1) <strong>in</strong> late summer; or<br />
<strong>in</strong> <strong>the</strong> bright red fruits <strong>of</strong> <strong>the</strong> common w<strong>in</strong>terberry<br />
throughout fail and w<strong>in</strong>ter. These also are common<br />
sights along nor<strong>the</strong>astern roads and hik<strong>in</strong>g<br />
trails; <strong>the</strong>y are <strong>the</strong> detaiIs that create visual diversity<br />
In a predom<strong>in</strong>antly forested landscape.<br />
The public engages ih a variety <strong>of</strong> forms <strong>of</strong><br />
recreation <strong>in</strong> red maple swamps. Depend<strong>in</strong>g upon<br />
<strong>the</strong> water regime and <strong>the</strong> pro&ity <strong>of</strong> <strong>the</strong> swamps<br />
open water, hunters nay pursue watedowl,<br />
deer, ruffed Gouse, rabbits, squirPels, or even<br />
r<strong>in</strong>g-necked pheasants (Phcrsknus ahhicus) <strong>in</strong><br />
<strong>the</strong>se habitats. <strong>Red</strong> maple swamps are frequented<br />
by birdwakhers as well, especially dur<strong>in</strong>g late<br />
spr<strong>in</strong>g when migrat<strong>in</strong>g warblers and o<strong>the</strong>r songbirds<br />
feed on <strong>in</strong>sects attracted to <strong>the</strong> flowers and<br />
break<strong>in</strong>g leaf buds <strong>of</strong> red maple trees. Canoe<strong>in</strong>g,<br />
hik<strong>in</strong>g, and photograph<strong>in</strong>g nature art, o<strong>the</strong>r forms<br />
<strong>of</strong> recreation that may be pursued <strong>in</strong> and along <strong>the</strong><br />
edges <strong>of</strong> red maple swamps. Pick<strong>in</strong>g native highbush<br />
blueberries is ano<strong>the</strong>r activity that is part <strong>of</strong><br />
<strong>the</strong> cultural heritage associated with <strong>the</strong>se forested<br />
wetlands.<br />
Biotic diversity, particularly <strong>the</strong> presence <strong>of</strong> rare,<br />
threatened, unique, or unusual plants axad animals,<br />
is itself an aspect <strong>of</strong> our natural heritage to which<br />
red maple swamps contribute. As noted previously,<br />
many species <strong>of</strong> plants and animals found <strong>in</strong> red<br />
maple swamps are classified <strong>in</strong> threatened or endangered<br />
conservation status categories by state<br />
agencies (see Appendixes B and D). Still, documentation<br />
<strong>of</strong> <strong>the</strong> flora and fauna (especially <strong>in</strong>vertebrates)<br />
<strong>in</strong> red maple swamps has been limited;<br />
more detailed surveys are needed throughout <strong>the</strong><br />
Nor<strong>the</strong>ast.<br />
Pollen preserved for thousands <strong>of</strong> years <strong>in</strong> <strong>the</strong><br />
sediments beneath red maple swamps provides<br />
tangible evidence <strong>of</strong> <strong>the</strong> changes <strong>in</strong> climate and<br />
plant communities that have occurred <strong>in</strong> <strong>the</strong><br />
Nor<strong>the</strong>ast s<strong>in</strong>ce <strong>the</strong> retreat <strong>of</strong> <strong>the</strong> glaciers<br />
(Beetham and Nier<strong>in</strong>g 1961). Thus, some red maple<br />
swamps may have considerable value for research<br />
and education.<br />
In highly urbanized areas <strong>of</strong> <strong>the</strong> Nor<strong>the</strong>ast, red<br />
maple swamps also provide a natural, low-cost<br />
form <strong>of</strong> open space. Frequently, <strong>the</strong> term open<br />
space is limited to aes<strong>the</strong>tics and recreational<br />
value, but <strong>in</strong> many cases its chief value may be <strong>in</strong><br />
reduc<strong>in</strong>g <strong>the</strong> visual and psychological impacts <strong>of</strong><br />
urbanization on humans m d <strong>the</strong>ir quality <strong>of</strong> life.<br />
Public parks, athletic fields, agricultural land,<br />
and o<strong>the</strong>r undeveloped uplands also provide open<br />
space, but wetlands are particularly well suited to<br />
this purpose for several reasons: (1) <strong>the</strong>y perform<br />
a variety <strong>of</strong> o<strong>the</strong>r functions, such as flood storage<br />
and water quality improvement, that are highly<br />
valued by society; (2) <strong>the</strong>y are unsuitable for most<br />
o<strong>the</strong>r land uses because <strong>of</strong> <strong>the</strong>ir wetness; and (3)<br />
<strong>the</strong>y are frequently distributed <strong>in</strong> a l<strong>in</strong>ear pattern,<br />
paraiieiir~g watercourses, which maximizes human<br />
contact with undeveloped parts <strong>of</strong> <strong>the</strong> landscape.<br />
<strong>Red</strong> maple swamps are especially effective<br />
open-space areas (Fig. 8.2); <strong>the</strong> trees and shrubs<br />
provide a tall, visual screen between developed<br />
areas and help to reduce noise emanat<strong>in</strong>g from
