Section 1075.20  Definitions

The following terms will be used throughout this Part:  

"Action" – construction, land management, or other activities that are authorized, funded, or performed in whole or in part by agencies of State and local governments and that will result in a change to the existing environmental conditions or may affect listed endangered or threatened species or their essential habitat or Natural Areas.

"Adverse Impact" – a direct or indirect alteration of the physical or biological features of the air, land or water which may affect the survival, reproduction or recovery of a listed species or that may diminish the viability of a Natural Area.

"Agency" – includes all agencies, boards and commissions which are under the jurisdiction of State or local governments.

"Agency Action Report" – a report submitted to the Department by agencies proposing an action(s) requiring consultation.  The information required to be submitted shall be sufficient to determine the presence or absence of a threatened or endangered species or Natural Area in the vicinity of the proposed action.

"Biological Opinion" – the component of the Detailed Action Report prepared by the Department, when a valid record of an occurrence for a threatened or endangered species or Natural Area exists within the vicinity of a proposed action.  This opinion will conclude whether the action will jeopardize the listed species present, destroy or adversely modify their essential habitat or adversely modify a Natural Area.

"Conservation" – utilization of all methods and procedures which are necessary to bring any endangered or threatened species to the point at which the protection provided by the Illinois Endangered Species Protection Act (Ill. Rev. Stat. 1991, ch. 8, par. 331 et seq.) [520 ILCS 10] are no longer necessary.  These methods and procedures include, but are not limited to, all activities associated with scientific resources management, such as research, census, habitat acquisition, habitat management restoration, and maintenance and propagation.

"Cumulative Effects" – direct and indirect effects of a proposed action(s) together with the identifiable effects of actions that are interrelated or interdependent with the action.  Indirect effects are those that are caused by the action but are later in time or farther in distance.  Interrelated actions are those that are a part of a larger action.  Interdependent actions are those that have independent utility apart from the action.

"Department" – means the Department of Natural Resources.

"Detailed Action Report" – a written report that is prepared by an agency when a threatened or endangered species or Natural Area has been identified within the vicinity of a proposed action.  This report shall contain sufficient information to make a judgement regarding the potential adverse impacts to a listed species or its essential habitat or a Natural Area.

"Essential Habitat" – is the physical and biological environment that is required to maintain viable populations of a listed species in order to ensure the survival and recovery of that species.

"Jeopardize" – to engage in an action which would reduce the likelihood of the survival or recovery of a listed species or would result in the destruction or adverse modification of the essential habitat of such a species or which would result in the destruction or adverse modification of a Natural Area.

"Listed Species" – is any species of plant or animal which has been listed as endangered or threatened by the Illinois Endangered Species Protection Board or the U.S. Fish and Wildlife Service.

"Natural Area" – is any area of land in public or private ownership which is registered under the Illinois Natural Areas Preservation Act [525 ILCS 30] or is identified in the Illinois Natural Areas Inventory.

"Vicinity" – the area surrounding the action, as determined by the life history requirements of the species of concern or proximity to a Natural Area.
