Potential for Occurrence on FLMR. Red-shouldered hawks were confirmed on FLMR. It is<br />
unclear if <strong>the</strong> birds breeds on <strong>the</strong> installation or are transients. Suitable habitat is present, and<br />
surveys should continue to determine if this species breeds in <strong>the</strong> area.<br />
Recommendations. Floodplain forests on FLMR should be maintained. Floodplain pools and<br />
wetlands provide important foraging habitat for this species, and accordingly, <strong>the</strong>se features<br />
should be maintained and restored.<br />
Sou<strong>the</strong>rn flying squirrel: Glaucomys volans (Linnaeus)<br />
Past Records. The sou<strong>the</strong>rn flying squirrel is widespread in <strong>the</strong> eastern U.S., reaching <strong>the</strong><br />
western limit its range in eastern <strong>Kansas</strong>. About a dozen occurrences are known in <strong>Kansas</strong>, most<br />
<strong>of</strong> which are in <strong>the</strong> two easternmost tiers <strong>of</strong> counties (KSNHI unpublished data), including<br />
Leavenworth (Bee et al. 1981). Brumwell (1951) reported a squirrel killed by workmen while<br />
felling a tree on FLMR. Five specimens labeled “West bank Missouri River, Ft. Leavenworth”<br />
with collection dates <strong>of</strong> 1 January-14 March 1955 are deposited in <strong>the</strong> University <strong>of</strong> <strong>Kansas</strong><br />
Museum <strong>of</strong> <strong>Natural</strong> History.<br />
Available Habitat and Surveys. This small, nocturnal squirrel inhabits deciduous and mixed<br />
forests, particularly beech-maple, oak-hickory, and poplar. Mature, closed-canopy forests near<br />
water are preferred. Squirrels readily use nest boxes and abandoned bird and squirrel nests. Nest<br />
boxes were used to survey for <strong>the</strong> species in floodplain and upland forests on FLMR. Three<br />
series <strong>of</strong> nest boxes (four boxes per site) were installed on 5 December 2002 and checked in<br />
April and November 2003 (Figure 3.1). No flying squirrels were found using nest boxes. Davis<br />
(2003) trapped unsuccessfully for this species on <strong>the</strong> installation. However, one sou<strong>the</strong>rn flying<br />
squirrel was captured while netting bats near <strong>the</strong> Boy Scout Camp on 2 June 2003 (C. Davis<br />
personal comm.). Sightings in 2003 include one animal on 3 May on <strong>the</strong> River Trail by S.<br />
Seltman (personal comm.) and reports by bow hunters in <strong>the</strong> cottonwood forest north <strong>of</strong> <strong>the</strong><br />
airfield (C. Davis personal comm.).<br />
Potential for Occurrence on FLMR. Flying squirrels were found during this study, with one<br />
confirmed record in White oak-Shagbark hickory Forest and several observations in <strong>the</strong><br />
floodplain forests. Limited records indicate that <strong>the</strong> sou<strong>the</strong>rn flying squirrel is an uncommon<br />
resident in larger forest tracts on <strong>the</strong> installation.<br />
Recommendations. Mature forest stands on <strong>the</strong> installation should be maintained. Additional<br />
surveys should be carried out if more detailed information about this species’ distribution and<br />
abundance is needed.<br />
Timber rattlesnake: Crotalus horridus Linneaus<br />
Past Records. The timber rattlesnake, <strong>the</strong> largest venomous snake in <strong>Kansas</strong>, is restricted in<br />
<strong>Kansas</strong> to counties in <strong>the</strong> eastern quarter. Specimens have been collected in Leavenworth and all<br />
surrounding <strong>Kansas</strong> counties (Collins 1993). Brumwell (1951) reported <strong>the</strong> species from Corral<br />
Creek, Government Hill, and o<strong>the</strong>r locations on FLMR. The Pest Control <strong>of</strong>fice has one timber<br />
