Section 133.4. Definitions

In addition to the definitions contained in section 102 of the act (relating to definitions), the following words and terms, when used in this chapter, have the following meanings, unless the context clearly indicates otherwise:

Endangered—Species in imminent danger of extinction or extirpation throughout their range in this Commonwealth if the deleterious factors affecting them continue to operate. The term includes:

(i) Species whose numbers have already been reduced to a critically low level or whose habitat has been so drastically reduced or degraded that immediate action is required to prevent their extirpation from this Commonwealth.

(ii) Species whose extreme rarity or periphery places them in potential danger of precipitous declines or sudden extirpation throughout their range in this Commonwealth.

(iii) Species that have been classified as ‘‘Pennsylvania Extirpated’’, but which are subsequently found to exist in this Commonwealth as long as the conditions listed in subparagraph (i) or (ii) are met.

(iv) Species determined to be ‘‘endangered’’ under the Endangered Species Act of 1973 (16 U.S.C.A. § § 1531—1544).

Threatened—Species that may become endangered within the foreseeable future throughout their range in this Commonwealth unless the casual factors affecting the organism are abated. The term includes:

(i) Species whose populations within this Commonwealth are decreasing or have been heavily depleted by adverse factors and while not actually endangered, are still in critical condition.

(ii) Species whose populations may be relatively abundant in this Commonwealth but are under severe threat from serious adverse factors that have been identified and documented.

(iii) Species whose populations are rare or peripheral and in possible danger of severe decline throughout their range in this Commonwealth.

(iv) Species determined to be ‘‘threatened’’ under the Endangered Species Act of 1973, that are not listed as ‘‘Pennsylvania Endangered.’’
