- Peat
- Generally, unconsolidated plant material primarily consisting of
undecomposed, or only slightly decomposed, organic matter accumulated
under water-soaked conditions. More specifically, a layer of organic
material containing plant residues that may show little, if any, morphological
change and that have accumulated as a result of submergence in water
or through being in a very wet environment. One of the basic building
blocks of the Canoe Country ecosystem.

(perke), and Latin perca, an ancient name for a common
spiny-finned European fish. Applied by extension to related species.
- Peregrine
- The largest, and rarest, of the Boundary Waters falcons (Falco

which has come into English as pilgrim. So named by medieval falconers
because the birds were taken, not as young from the nest, but in migration,

The vast majority of North Country plants are perennial. From
the Latin, perennis, "through;" and annus, "a year."

Center (BWCAW Entry Point 86) and makes use of some old
logging roads.
- Prairie Portage
- The Border Route portage (20 rods) between Basswood and Sucker lakes
and the site of a popular Canadian Port of Entry. This direct
access to the Quetico goes
a long way in explaining the ongoing popularity of the Moose Lake entry
point, the busiest in the BWCAW, immediately to the south.
- Precambrian
- The ancient epoch of geological time (3.5 billion to 600 million
years ago), marked in the North Country by the Early Precambrian Keewatin,
Laurentian, Knife

- Prothallium
- In the reproductive cycle of ferns, a self-sustaining, independent
plant, developing out of the growing spore. Green, heart shaped,
½" or less in diameter, and lying flat upon the ground it little
resembles a fern, when noticed at all. The Prothallium grows Antheridia

(female organs) on its underside which produce the spermatazoids and
eggs that combine and grow into what we think of as a fern. Also
known as Gametophyte.
- Pubescent
- A general term for hairiness, often used to describe the surface
of plant stems or leaves. (Hairy Solomon's Seal, Polygonatum
pubescens, for example). From the Latin, pubescere, "to
become mature."
- Pulp
- The wood fibers of trees, ground up for use in the manufacture of
paper. A common use of those North Country trees which are logged
but unsuitable, because of their size or species, for use as sawtimber.
A compelling reason to recycle paper.
