DEPARTMENT OF THE INTERIOR

50 CFR Part 17

RIN 1018–AE87

Endangered and Threatened Wildlife

and Plants; Reopening of Comment

Period on Proposed Threatened Status

for the Plant Gaura neomexicana ssp.

coloradensis

AGENCY: Fish and Wildlife Service,

Interior.

ACTION: Proposed rule; notice of

reopening of comment period.

SUMMARY: We, the Fish and Wildlife

Service (Service), pursuant to the

Endangered Species Act of 1973, as

amended (Act), reopen the comment

period on the proposal to list the plant

Gaura neomexicana ssp. coloradensis

(Colorado butterfly plant) as a

threatened species. The comment period

is extended to accommodate the public

notice requirement of the Act and to

consider any new scientific information.

In addition, reopening of the comment

period will allow further opportunity

for all interested parties to submit

comments on the proposal, which was

published on March 24, 1998 (63 FR

14060). We are seeking comments or

suggestions from the public, other

concerned governmental agencies, the

scientific community, industry, or any

other interested parties concerning the

proposed rule. Comments already

submitted on the proposed rule need

not be resubmitted as they will be fully

considered in the final determination.

DATES: The reopened comment period

closes June 16, 2000.

ADDRESSES: Copies of the proposed rule

are available on the World Wide Web at

<mountain-prairie.fws.gov/endspp/

plants/>. You may also request copies

from, and submit comments and

materials concerning this proposed rule

to, the Field Supervisor, U.S. Fish and

Wildlife Service, 4000 Airport Parkway,

Cheyenne, Wyoming 82001. Comments

and materials received will be available

for public inspection, by appointment,

during normal business hours at the

above address.

FOR FURTHER INFORMATION CONTACT:

Mike Long, Field Supervisor, Wyoming

Field Office (see ADDRESSES section),

telephone 307/772–2374; facsimile 307/

772–2358.

SUPPLEMENTARY INFORMATION:

Background

On March 24, 1998, we published a

rule proposing threatened status for

Gaura neomexicana ssp. coloradensis in

the Federal Register (63 FR 14060). The

original comment period closed on May

26, 1998. Section 4(b)(5)(D) of the Act

(16 U.S.C. 1531 et seq.) requires us to

‘‘publish a summary of the proposed

regulation in a newspaper of general

circulation in each area of the United

States in which the species is believed

to occur.’’ Due to an oversight, we failed

to complete this requirement. To correct

the oversight, we are reopening the

comment period for this proposal to list

G.n. ssp. coloradensis and publishing

the required notices. The comment

period now closes on June 16, 2000.

Written comments should be submitted

to the Service (see ADDRESSES section).

Gaura neomexicana ssp. coloradensis

is a short-lived, perennial herb endemic

to moist soils in mesic or wet meadows

of floodplain areas in southeastern

Wyoming, northcentral Colorado, and

extreme western Nebraska. This early to

mid-seral stage species occurs primarily

in habitats created and maintained by

streams active within their floodplains,

with vegetation that is relatively open

and not overly dense or overgrown. The

disturbance of riparian areas that

contain native grasses by agricultural

conversion, water diversions,

channelization, and urban development

threaten G.n. ssp. coloradensis by

Federal Register / Vol. 65, No. 96 / Wednesday, May 17, 2000 / Proposed Rules 31299

changing habitat significantly enough to

preclude survival of viable populations.

Comments from the public regarding

the accuracy of this proposed rule are

sought, especially regarding:

(1) Biological, commercial trade, or

other relevant data concerning any

threat (or lack thereof) to this species;

(2) The location of any additional

populations of this species and the

reasons why any habitat should or

should not be determined to be critical

habitat pursuant to section 4 of the Act;

(3) Additional information concerning

the range, distribution, and population

size or trend of this species;

(4) Current or planned activities in the

subject area and their possible impacts

on this species;

(5) Biological or physical elements

that best describe Gaura neomexicana

ssp. coloradensis habitat that could be

essential for the conservation of the

species;

(6) Information regarding genetic

differences and similarities within and

between populations of Gaura

neomexicana ssp. coloradensis;

(7) Possible alternative noxious weed

control, grazing, farming, and water

management practices that will reduce

or eliminate impacts to Gaura

neomexicana ssp. coloradensis; and

(8) Other management strategies that

will conserve the species throughout its

range.

Comments previously submitted

during the first comment period need

not be resubmitted, as they will be fully

considered in the final determination.

Author. The primary author of this

document is Mary Jennings of the

Wyoming Field Office (see ADDRESSES

section).

Authority: The authority for this action is

the Endangered Species Act of 1973 (16

U.S.C. 1531 et seq.).
