Tail averages 42-60 mm (1.6 to 2.3 inches). Dorsum pale gray with an indistinct mid-dorsal stripe. Tail white with an incomplete dorsal stripe. Flanks and ventrum pure white. This race differs from the other races in the following ways: albifrons - Peromyscus polionotus ammobates is paler and grayer with hind foot being significantly longer; griscobracatus - the ear of P. p. ammobates is intermediate in length between albifrons and griscobracatus, but otherwise resembles griscobracatus; leucocephatus - P. p. ammobates is generally similar in color, but averages much darker and less pure; polionotus - P. p. ammobates is paler than polionotus (01). The name Mus polionotus of Wagner (1843) was changed to Peromyscus subgriseus by Bangs in 1898 and later to Peromyscus polionotus by Osgood in 1907 (02,07,08). Osgood did not have specimens of Peromyscus polionotus from coastal areas of Florida when Taxonomy - 1 (DRAFT) - Taxonomy Species MOUSE, BEACH, ALABAMA Species Id ESIS054011 Date 14 MAR 96 he discribed the subspecies P. p. albifrons Osgood, 1909 (07). Later, Howell also recognized beach mice from the region around Choctawhatchee Bay, extreme western Florida, and ocean beaches in southeastern Alabama as P. p. albifrons, but recognized that there was a lack of specimens for defining the ranges of various races (06,09). "Prior to a detailed study by Bowen (01), involving genetics, morphology, historical geology, and habitat, only 3 subspecies were recognized in Florida. Bowen determined that variation was much more extensive than previously thought, and he described 5 new subspecies, including the Alabama beach mouse (P. p. ammobates), originally found on coastal dunes from Fort Morgan to Alabama Point, and on Ono Island, Baldwin County, Alabama" (02).

At Fort Morgan, the 1980 habitat was characterized by Uniola paniculata and Panicum amarum on the first two rows of low dunes (less than 2 meters high). A vegetated flood basin on the mainland side of these dunes supported Panicum amarum, P. repens, Andropogon maritimus, Distichlis spicata, and Serenoa repens. The woody vegetation on higher (14 m) relic dunes was predominantly Quercus myrtifolia of various ages mixed with pines further in from the coast. The Gulf Highlands and Pine Beach (Bon Secour National Wildlife Refuge) habitats were essentially alike with the exception that the Pine Beach area was the largest uninterrupted tract of habitat along the Alabama coast. In 1980, dune height ranged up to 12 meters with vegetation of Uniola paniculata and Panicum amarum. A line of isolated tertiary dunes at Pine Beach were separated by bare sand areas and were covered with communities of Andropogon maritimus, Serenoa repens, Quercus virginiana var. maritima, Q. myrtifolia, Uniola paniculata, Panicum amarum, Solidago panciflosuclosa, Paronychia sp. and Heterotheca subaxillaris (01). All of the other 1980 habitats on Fort Morgan peninsula have either been destroyed or severely altered. Suitable beach mouse habitat still exists on Gulf State Park and at Romar Beach. Meyers (06) concludes that mature dune ecosystems with large elevation differences (greater than 4 m) will contain the optimum microhabitat. The number of ghost crab burrows may be associated with optimum beach mouse habitat for use as escape cover (06). Any dune within the primary and tertiary lines should not be altered or otherwise disturbed. Differences in vegetative patterns and community structure along with differences in sand dune configuration and genesis on the Florida and Alabama coasts have produced different micro-habitat types for the extant populations of beach mice. Because of these differences, it is impossible to form valid generalizations about allopatric populations by gathering data from only one race. It is recommended that each peripheral isolate be researched individually, rather than relying on data from a single geographical area to formulate habitat site indices Habitat Associations - 1 and range wide management practices.

LIFE HISTORY

FOOD HABITS: There are no published scientific data concerning the food habits of Peromyscus polionotus ammobates (Alabama beach mouse). Holliman has found evidence of Uniola paniculata and Panicum amarum being used as a food source (10). Seeds are definitely consumed; however, it is not clear to what extent roots, stems or leaves of these or other plants might also be consumed. Invertebrates are probably consumed when seeds are scarce (14). HOME RANGE/TERRITORY: There are no published scientific data concerning the home range/territory of Peromyscus polionotus ammobates (Alabama beach mouse). Research by Holliman was conducted on concentrated post storm populations that were isolated and not homogenuously distributed (10). PERIODICITY: There are no published scientific data concerning periodicity of Peromyscus polionotus ammobates (Alabama beach mouse). MIGRATION PATTERNS: Peromyscus polionotus ammobates (Alabama beach mouse) is nonmigratory. COVER/SHELTER REQUIREMENTS: Sparsely vegetated sand dunes, particularly between the primary and tertiary lines, are essential for the cover/shelter requirements of Peromyscus polionotus ammobates (Alabama beach mouse). Tunnel systems and living chambers are constructed within the root network of dune vegetation. Strong predictors of optimum beach mouse habitat seem to be site maximum elevations and differences (mature dunes 8 meters elevation with elevational differences >4 meters); high densities of mouse and ghost crab burrows for escape cover; proximity of forest to beach; sparse presence of needle-leave shrubs (approximately 1 percent); moderate number of ground plant species (average 3.5); and low cover value of sea oats (8.3 percent) (06). However, additional studies are needed to determine habitat needs more specifically and conclusively. REPRODUCTIVE SITE REQUIREMENTS: See COVER/SHELTER REQUIREMENTS. REPRODUCTIVE CHARACTERISTICS: Trapping of Peromyscus polionotus ammobates during a study in October 1982 revealed 70 percent of the adult females with evidence of reproductive activity (33 percent were pregnant and 67 percent were lactating). Only one of seven adult males had descended testes (06). More work is needed before trends can be predicted. PARENTAL CARE: There are no scientific data available relative to the parental care of Peromyscus polionotus ammobates (Alabama beach mouse). Life History - 1 (DRAFT) - Life History Species MOUSE, BEACH, ALABAMA Species Id ESIS054011 Date 14 MAR 96 POPULATION BIOLOGY: Although Meyers (06) and Holliman (05) collected some data relative to the population biology of Peromyscus polionotus ammobates (Alabama beach mouse) more data over a longer period of time is needed before a valid trend can be predicted. Holliman (05) estimated approximately 875 individuals for the estimated 134.6 ha of post-storm habitat. Plant-product consuming animals are generally limited by food. However, for P. p. ammobates, a place to live may be as important as food (11,12). Natural or introduced predators may decrease population densities when habitat conditions are less than optimal (06). Beach development can act to decrease the quality and amount of habitat; increase the number of potential predators/competitors; isolate populations reducing immigration and emigration; and subject local populations to extirpation from natural catastrophes (06). Undeveloped preserves of 50 to 200 ha of suitable habitat are needed with corridors of suitable habitat joining smaller areas to provide for repopulation following natural catastrophes (06). SPECIES INTERRELATIONSHIPS: Humphreys and Barbour (08) suggest that the House Mouse (Mus musculus) impacts Peromyscus polionotus ammobates (Alabama beach mouse) populations. Meyers (01) and Holliman (05) did not find this to be the case with P. p. ammobates. House cats and red foxes are probably the main predators of P. p. ammobates (05,06). Over-wintering savannah sparrows (Passerculus sandwichensis) may impact P. p. ammobates populations through competition for food (09). Ghost crab burrows may be important for P. p. ammobates as escape cover. The number of crab burrows seems to be an important feature of the microhabitat. The relationship seems to be commensal (i.e., benefits P. p. ammobates but does not effect the crab) (06). OTHER LIFE HISTORY DESCRIPTORS: No information available. Life History - 2

Problems have Management Practices - 1 (DRAFT) - Management Practices Species MOUSE, BEACH, ALABAMA Species Id ESIS054011 Date 14 MAR 96 been compounded by heavy recreational and other multi-use demands on the dune ecosystem (i.e., residential construction, utility right-of-ways, roads, and recreational use). Since September 12, 1979, the primary and secondary dune lines have not had a chance to fully recover due to a combination of successive damaging tropical storms and real estate development (primarily resort and residential). The storms of 1985 destroyed approximately 75 percent of the primary dunes at the Fort Morgan Peninsula. Twenty percent of the man-made primary dunes east and west of the Gulf State Park Pavillion and 50 percent of the primary dunes in front of the Gulf State Park Resort Motel were destroyed. Approximately 20 to 30 percent of the dunes west of the Gulf State Park Resort Motel were destroyed. Approximately 20 to 30 percent of the dunes west of the Gulf State Park fishing pier were destroyed by these 1985 storms (07). Human pressure for beach use on non-private lands has caused destruction and subsequent erosion of those remaining dune lines on Federal and State property. Lack of enforceable laws that would control off-road vehicles and human foot traffic to sensitive beach areas has contributed to a sub-optimum habitat. Competition by house mice and overwintering savannah sparrows may be a problem although there is no data to substantiate this (05). Predation by house cats, red fox, dogs, raccoons, skunks, weasels, and great blue herons have been documented (05,06). In the future, probably the only habitat that will remain will be at the Bon Secour National Wildlife Refuge and at the State of Alabama units. Fort Morgan and Gulf Shores Management plans for these areas are badly needed. Dune destruction and/or alterations of any type would have an immediate effect on this population. Without the proper cover and food supply these mammals would be vulnerable to predators, especially if they had to move to other areas because of fragmentation of habitat. Large tracts of habitat, such as that at Fort Morgan and Bon Secour National Wildlife Refuge should be left intact. More data is needed before the effectiveness of "corridors between populations to allow for immigration and emigration" can be determined. Sand deposited on or near beach mouse habitat from U.S. Army Corps of Engineers routine channel maintenance program may be a potential threat to beach mouse habitat. APPROVED PLAN: U.S. Fish and Wildlife Service. 1987. Choctawhatchee Beach Mouse, Perdido Key Beach Mouse, and Alabama Beach Mouse Recovery Plan. U.S. Fish and Wildlife Service, Atlanta, GA. 45 pp. Recovery actions for the Alabama beach mouse (Peromyscus polionotus ammobates) are included in the Recovery Plan for the 3 subspecies of beach mice, the Choctawhatchee, Perdido Key and Alabama beach mice. The primary recovery objectives for each of these mice are to stabilize the present populations by preventing further habitat deterioration, and to reestablish populations in areas from which they have been extirpated in order to reduce the possibility of an entire Management Practices - 2 (DRAFT) - Management Practices Species MOUSE, BEACH, ALABAMA Species Id ESIS054011 Date 14 MAR 96 subspecies being brought to extinction by a catastrophic storm. Each subspecies of beach mouse can be considered for downlisting to Threatened when there are 3 distinct, self-sustaining populations in each of the Critical Habitat areas, and a minimum of 50% of the Critical Habitat is protected and occupied by mice. Because of the extensive and permanent loss of habitat for these mice, it will probably never be possible to safely remove them entirely from the protection of the Act. The following management actions are recommended for recovery of the Alabama beach mouse: 1. Protect habitat from further human encroachment. a. Reevaluate all regulations for public use of dunes in light of beach mouse needs. Closing areas to human use, restricting night activities, and prohibiting vehicular traffic may be needed. Install additional boardwalks as needed to protect dunes from pedestrian traffic. b. Maintain predator control programs focused on feral and domestic cats and red foxes, where needed. c. Determine the effect of feral house mice on beach mice and, if warrented, eliminate house mice from beach mice habitat. d. Utilize cooperative agreements among Federal and/or State agencies to share resources and technical expertise. e. Improve suitability of habitat in areas where habitat is available (e.g., dune restoration and planting suitable vegetation). f. Use cooperative agreements, land exchange, fee title acquisition, and/or easements with private landowners to preserve habitat. Monitor activities for private lands through planning boards, rezoning applications, permit applications, etc. Encourage ordinances and restrictive agreements in sales and rental contracts requiring house cats to be confined. 2. Reestablish and/or supplement populations by transplanting wild mice and/or reintroducing captive bred mice. 3. Develop an educational program for the public. 4. Develop emergency procedures to provide protection to beach mouse habitat in case of off-shore oil spills. Ongoing recovery activities include dune restoration and beach mouse population surveys.
