Endangered and Threatened Wildlife and Plants; Reopening of 
Comment Period on Proposed Endangered Status for Puccinellia Parishii 
(Parish's Alkali Grass)

AGENCY: Fish and Wildlife Service, Interior.

ACTION: Proposed rule; notice of reopening of public comment period.

-----------------------------------------------------------------------

SUMMARY: The Fish and Wildlife Service provides notice that the public 
comment period is reopened for the proposal to list Puccinellia 
parishii (Parish's alkali grass) as an endangered species pursuant to 
the Endangered Species Act of 1973, as amended. This small annual grass 
occurs near desert springs, seeps, and seasonally wet areas in Apache, 
Coconino, and Yavapai counties, Arizona; San Bernardino County, 
California; and Catron, Cibola, Grant, Hidalgo, McKinley, Sandoval, and 
San Juan counties, New Mexico.

DATES: This comment period closes on August 19, 1998.

ADDRESSES: Written comments and materials should be sent to the Field 
Supervisor, New Mexico Ecological Services Field Office, U.S. Fish and 
Wildlife Service, 2105 Osuna Road, NE., Albuquerque, New Mexico 87113. 
Comments and materials received will be available for public inspection 
during normal business hours, by appointment, at the above address.

FOR FURTHER INFORMATION CONTACT: Charlie McDonald at the above address 
or telephone (505) 346-2525.

SUPPLEMENTARY INFORMATION:

Background

    Puccinellia parishii (Parish's alkali grass) was proposed for 
designation as an endangered species under the Endangered Species Act 
of 1973, as amended (Act) (16 U.S.C. 1531 et seq.) on March 28, 1994 
(59 FR 14378). A 60-day public comment period was provided on the 
proposal. All interested parties were requested to submit factual 
reports or information that might contribute to the accuracy and 
effectiveness of any final action resulting from the proposal. The U.S. 
Fish and Wildlife Service (Service) received one request for a public 
hearing, and a notice announcing the public hearing and reopening the 
comment period was published in the Federal Register on August 30, 1994 
(59 FR 44700). The public hearing was held on September 15, 1994, in 
Tuba City, Arizona.
    Following the initial and reopened comment periods and public 
hearing, the Service received additional information on the 
distribution, abundance, habitat requirements, and threats for Parish's 
alkali grass. This new information is summarized in the following 
paragraphs.
    Parish's alkali grass is now known from 29 sites as opposed to the 
10 sites reported in the proposed rule. The known sites in New Mexico 
have increased to 16 from the 1 that was reported in the proposed rule. 
The new sites for New Mexico are in Catron (1), Cibola (1), Hidalgo 
(1), McKinley (6), Sandoval (4), and San Juan (2) counties. The 1 site 
reported in the proposed rule is in Grant County. The known sites in 
Arizona have increased to 11 from the 7 that were reported in the 
proposed rule. The new sites for Arizona are in Apache (3) and Yavapai 
(1) Counties. The 7 sites reported in the proposed rule are in Coconino 
County.
    The known sites in California have decreased to 1 from the 2 that 
were reported in the proposed rule. Dr. Andrew Sanders of the 
University of California, Riverside identified the

[[Page 38804]]

plants from Edwards Air Force Base in Kern County as Puccinellia 
simplex rather than P. parishii (C. Rutherford, U.S. Fish and Wildlife 
Service, in litt. 1995). The other California site reported in the 
proposed rule is in San Bernardino County.
    Some of the newly discovered sites extend the overall range of the 
species. In particular, discoveries in northwestern New Mexico extend 
the species' range about 300 km (200 mi) eastward from previously known 
sites in Arizona, and the discovery in west-central Arizona extends the 
species' range about 240 km (150 mi) southwestward in that state. Many 
of the new sites fill gaps in the known distribution making populations 
much less disjunct from one another than previously believed.
    Some newly discovered sites for Parish's alkali grass indicate the 
species occupies a broader range of habitats than previously supposed. 
In addition to sites near desert springs and seeps, some newly 
discovered sites are in areas where the soils are subirrigated and wet 
only during the winter and spring months. These sites are generally not 
identified as springs on maps and are only noticeable because their 
greener vegetation contrasts with the surrounding brown vegetation 
during the spring months. One newly discovered site occurs at 2,240 m 
(7,350 ft) in elevation, which is 410 m (1,350 ft) higher than any of 
the sites in the proposed rule. These discoveries greatly increase the 
number of potential sites where Parish's alkali grass might be found.
    Some of the newly discovered sites indicate Parish's alkali grass 
may withstand disturbance better than previously suspected. At several 
sites, cattle have closely cropped the vegetation and severely trampled 
the area. However, Parish's alkali grass persists at the sites. In one 
instance, a highway right-of-way fence protects part of the site from 
grazing. The protected area has a dense stand of sweet clover 
(Melilotus sp.) and no Parish's alkali grass, but the grass is abundant 
in the grazed area only a few meters away. Some disturbance likely 
reduces competition and creates microsites for seedling establishment 
for Parish's alkali grass, which is a short-statured annual plant.
    No final decision has been made on whether to give Parish's alkali 
grass protection under the Act or to withdraw the listing proposal. In 
consideration of the length of time since the initial proposal and the 
new information about the species, the Service is reopening the comment 
period and seeking comments or suggestions from the public, other 
concerned governmental agencies, the scientific community, industry, or 
any other interested party concerning the proposed rule. The Service is 
seeking any other new information that may have been developed since 
the proposal was published, and that may expand the current knowledge 
of the status, distribution, or threats for Parish's alkali grass. The 
new comment period closes on August 19, 1998. Any comments should be 
sent to the Field Supervisor, New Mexico Ecological Services Field 
Office (see ADDRESSES section).
