Dupage County Forest Preserve District for the Hine's Emerald Dragonfly
Environmental Action Statement/ Screening Form - PDF Version
I. Project Information
A. Project name:
Safe Harbor Agreement for Hine's emerald dragonfly (Somatochlora hineana) on Lands Owned by the Forest Preserve District of DuPage County (DISTRICT)
B. Affected species:
Hine's emerald dragonfly (Somatochlora hineana)
C. Project size (in acres): Approximately 15 acres
D. Brief project description including conservation elements of the plan: The objectives of the management activities include efforts to create rivulet systems that are suitable Hines emerald dragonfly (HED) larval breeding habitat. This project will enable the partners to
experimentally manipulate flow rate, temperature, and degree of permanence; and to allow monitoring
of larval HED recruitment, survival rates, and restoration of a narrow band of habitat along each rivulet
which mimics the structure of known breeding habitat. These objectives should be accomplished in a
way that contributes to or does not compromise longer term and more extensive habitat restoration
efforts on the site.
A detailed hydrogeologic characterization study will be completed and the results used to inform the
final design of these restoration efforts. The design will also be guided by the interdisciplinary HED
working group (HEDWG) that has been established by the Illinois State Toll Highway Authority
(ISTHA). Hydrogeologic monitoring will also be conducted throughout the restoration efforts. The
details of the fmal design and monitoring program will be reviewed and approved by the SERVICE
and the DISTRICT prior to implementation.
II. Does the SHA fit the criteria as described in the SHA policy? Yes
A. Are the effects of the SHA less than significant on the rangewide population of federally listed,
proposed, or candidate species or other wildlife and their habitats covered under the SEA?
Hine's emerald dragonfly (HED): Yes. The effects on HED are less than significant or ultimately beneficial
on a rangewide basis. The efforts under this SHA would be to learn how to create or restore suitable
habitat in places that currently lack some or all of the essential elements of suitable habitat in order to
provide additional breeding sites and larval habitat. Careful monitoring will be conducted both of the
newly created habitat and nearby occupied habitat. This will enable the SERVICE to determine the
success of the new habitat creation/restoration and any potential effects on nearby habitat and
populations. In Illinois, it is currently thought that the HED population is composed of several
subpopulations that may function as a metapopulation. The monitoring for this project and ongoing
genetics and population research on the HED will enable the SERVICE to ensure that the new habitat
is not acting as a population sink.
B. Are the effects of the SHA minor or negligible on other environmental values or resources
(e.g. air quality, geology and soils, water quality and quantity, socio-economic, cultural
resources, recreation, visual resources, etc.)?
The proposed actions under this SHA will be minor or negligible on other environmental values or
resources. There are no impacts expected or conceivably possible on air quality, geology and soils,
water quality and quantity, socio-economic, cultural resources, recreation, or visual resources. There
will be very minor disturbance of soil during installation of any permanent piping systems to convey
water from the artesian well to the rivulet creation locations, and minimal emissions are expected. The
site is entirely within public lands owned by the DISTRICT who can control access during
construction. No structures shall be constructed nor will there be other changes to visual resources.
Recreational values will not be impacted by this action. The proposed reestablishment sites are on one
landowner's property, and the adjacent properties are managed by the Department of Energy (Argonne
National Laboratory) and other private commercial entities. Downstream gradient habitat is not
expected to be altered.
No socio-economic values should be impacted, and this land is entirely within Waterfall Glen Forest
Preserve and bounded by Argonne and the Des Plaines River and associated canals. This project will
in no way affect access or use of the River or canals.
C. Would the impacts of this SHA, considered together with the impacts of other past, present,
and reasonably foreseeable similarly situated projects &result, over time, in cumulative effects
to environmental values or resources which would be considered significant?
Yes, the proposed action would NOT result in significant cumulative effects to environmental values
or resources. The area is within a natural landscape managed as a natural area, and with no residential
areas immediately downstream of the project site. This project is consistent with existing land uses,
and no changes in cusrent land use or management is anticipated, either on private or Federal lands.
Therefore, no significant cumulative effects to environmental or resource values are anticipated.
III. Do any of the exceptions to categorical exclusions apply to this SHA? (From 516 DM 2.3,
Would implementation of the SHA:
A. Have significant adverse effects on public health or safety?
No. The covered species is not dangerous or known to be vectors of any human pathogens, nor would
its habitat attract other such species.
B. Have adverse effects on such unique geographic characteristics as historic or cultural
resources, park, recreation or refuge lands, wilderness areas, wild or scenic rivers, sole or
principal drinking water aquifers, prime farmlands, wetlands, floodplains, or ecologically
significant or critical areas, including those listed on the Department's National Register of
No. There is minimal construction to install water pipes and flow controls. No structures would be
affected or constructed. There is no other ground breaking, or any other destiuctive activity associated
with this action.
C. Have highly controversial environmental effects?
No. The covered DISTRICT property is surrounded on the north by Federal lands managed by DOE.
The remaining areas not within Waterfall Glen Forest Preserve are private but would not be affected by
the proposed action. Moreover, habitat restoration actions such as these are within the normal
practices and mission of the DISTRICT on all of its properties.
D. Have highly uncertain and potentially significant environmental effects or involve unique or
unknown environmental risks?
No. This habitat restorationlcreation effort uses combinations of standard restoration techniques that
involve only localized manipulation of hydrology and vegetation to create habitat the mimics nearby
E. Establish a precedent for future action or represent a decision in principle about future
actions with potentially significant environmental effects?
No. Similar agreements are being drafted under the SHA policy, but each agreement is negotiated with
the applicant and is individualized based upon the participants and the resource values included.
F. Be directly related to other actions with individually insignificant but cumulatively significant
No. While this action is similar to a planned Federal action, neither action is likely to be significant in
either individual or cumulative effects.
G. Have adverse effects on properties listed or eligible for listing on the National Register of
No. The FWS is unaware of any sites within the Agreement's covered area listed or eligible for listing
on the National Register of Historic Places. It is unlikely that any action under this Agreement would
alter any such property to make it ineligible or harm an existing listed property.
H. Have adverse effects on listed or proposed species, or have adverse effects on designated
Critical Habitat for these species?
No. After reviewing the current status of the HED, the environmental baseline for the action area, the
effects of proposed enhancement of survival permit issuance, and the cumulative effects, it is the
SERVICE'S biological opinion that the action, as proposed, is not likely to jeopardize the continued
existence of HED.
This no jeopardy finding is supported by the following:
The SHA will result in a net conservation benefit for HED, as required by the SERVICE'S Safe Harbor
Policy. Habitat improvements will likely contribute to HED recovery long after the expiration of the
SHA. Without the SHA, the enrolled lands at Waterfall Glen Forest Preserve would not likely support
suitable habitat for HED in the foreseeable future.
Critical Habitat was designated for the HED in September 2007. This included portions of Waterfall
Glen Forest Preserve that generally exhibited the primary constituent elements. The "fish farm parcel"
is not designated as critical habitat since it does not contain any of the constituent elements and does
not provide any suitable babitat. Thus, any changes to the fish farm parcel will not affect critical
habitat directly. The immediately adjoining lands described above in the enrolled project lands is
within a unit of designated critical habitat, due to its proximity to the Emerald Fen area that does
provide suitable HED breeding habitat. The specific area within the enrolled lands however, does not
currently exhibit any suitable breeding habitat and lacks the primary constituent elements for HED
habitat. The area will be managed and manipulated to create andlor restore suitable HED habitat, by
establishing suitable hydrologic regimes, rivulet structure, and native vegetation. While these changes
will affect an area designated as critical habitat, it will not adversely affect critical habitat. It is intended to provide beneficial changes and provide increased area of suitable habitat containing all
primary constituent elements.

I. Have adverse effects on wetlands, floodplains or be considered a water development project
thus requiring compliance with either Executive Order 11988 (Floodplain Management),
Executive Order 11990 (Protection of Wetlands), or the Fish and Wildlife Coordination Act?
No impacts to wetlands or floodplains are anticipated. Additional wetland habitat may be created by
J. Threaten to violate a Federal, State, local, or tribal law or requirement imposed for the
protection of the environment?
No. All actions have been and will continue to be coordinated with appropriate state and local
IV. ENVIRONMENTAL ACTION STATEMENT
Based on the analysis above, the Safe Harbor Agseement for Hine's emerald dragonfly (Somatochlora
hineana) on Lands Owned by Forest Preserve District of DuPage Countv (DISTRICT). within the
Waterfall Glen Forest Presel-ve meets the qualifications for a SHA whose implementation represents a
class of actions which do not individually or cumulatively have a significant effect on the human
environment. Therefore, this action is categorically excluded from further NEPA documentation as
provided by 5 16 DM 2, Appendix 1 and 51 6 DM 6, Appendix 1.
