Eric Rickart Field Notes 2018

Field notes for Eric A. Rickart covering collecting activities from 2018

Eric A. Rickart 2018 Utah: Washington Co., Lytle Ranch Preserve, Beaver Dam Wash 31 March | left Salt Lake late morning on Wednesday 30 March accompanying Duke Rogers for field work on the Navajo Nation in northern Arizona and southcentral Utah. Duke has collecting permits for Arizona and the Navajo Nation, and added me as a co-permittee. The primary purpose was to collect two species: Perognathus amplus for a project Jim Patton and Duke are working on involving the systematics of the P. jongimembris species group, and Peromyscus truei for Duke’s ongoing project on that species. We drove down through St. George to the Lytle Ranch, which the Bean Museum manages, so that Duke could talk with the on-site manager Heriberto and check in on one of the research groups working here. In the late afternoon, we drove off of the Lytle Ranch property to a site where Duke trapped with his Mammalogy class this past fall (1.2 km E, 10.3 km S Scarecrow Peak) where we each set lines of 40 Sherman traps in a dry wash bisected by a road south of the Preserve. This morning, my traps held 6 Dipodomys merriami, 1 Chaetodipus formosus, and 1 Neotoma lepida. We also were given a fresh P. maniculatus that Heriberto captured in one of the buildings Lytle Ranch buildings which Duke gave to me. All of these animals were killed and placed on dry ice this morning. We left Lytle Ranch late morning, reaching Flagstaff in the early afternoon. From there, we drove north on US 89 onto the Navajo Nation lands continuing up the vicinity of: P ge ee ‘Met. 2 Oe ad © s oe ‘- in an a pede ete ~4 GS —" tf ote * = ia Eric A. Rickart 2018 Arizona: Coconino County, Navajo Nation, Cameron ee The vicinity of Cameron was the first place we hoped to find P. amplus. We took AZ rte. 64 westbound to a point where we found a good side road into desert shrub habitat. This locality is south of the Little Colorado River which lies in a deep canyon at this point and is a formidable barrier. We both set 40 Sherman traps at this site (1.0 km S, 10.0 km W Cameron). After this, we drove several km further west to a point near the western boundary of tribal land in pinyon-juniper woodland at an elevation of 1925 m. We both set 40 Sherman traps in this habitat and found a good place nearby to camp for the night. 1 April Pretty cold during the night, partly cloudy with a full moon. a Our traps in the pinyon-juniper had low success, but brought 4 P. truei —| took only one, but Duke had set his traps in an area with more rocks and had Slightly better success. Our traps down near Cameron did much better — mine held 1 P. crinitus and 8 P. amplus. Duke took 6 P. amplus here. We drove back into Flagstaff to replenish dry ice then returned north driving up 89, crossing the Little Colorado at Cameron, and the past the junction with US 160 where we found a secluded spot near the junction of 89 and Navajo rte. 6134 and spent some time preparing specimens. | froze the series of P. amplus from my trap line and prepared the other two mice | had caught. In the afternoon, we drove a short distance west on rte. 6134 to a site where we each set 40 traps (5.6 km S, 7.1 km W Moenave, 1455 m). } Eric A. Rickart 2018 Nee Ee Ne Resse Arizona, Coconino County, Navajo Nation and Hopi Reservation 1 April (cont.) We drove east on US 160 to Moenkopi and then southeast on AZ rte 264 to a site where we each set 40 traps — although we assumed we were still on Navajo tribal lands, we later discovered we were on the Hopi Reservation at this site (2.4 km S, 3.2 km E Moenkopi, 1525 m) — there were no boundary markers to indicate this. Habitat at this site was much sandier and with abundant small mammal sign. We returned to the spot where we prepared specimens and set up camp for the night. Duke set a box of Shermans around near camp. 2 April Duke’s traps around camp took nothing. Our traps to the west on rte. 6134 took 1 P. amplus and 1 P. maniculatus (EAR) and 2 P. amplus and 1 Neotoma albigula (DSR). My traps SE of Moenkopi took 1 P. maniculatus and three Onychomys leucogaster, one of which (an adult male) is the largest grasshopper mouse I’ve ever trapped. Duke took Onychomys and Dipodomys ordii in his traps here. We spent some time preparing specimens (freezing others on dry ice) and then continued further north on US 89 to the area around Bitter Springs at the junction of US 89A which crosses the Colorado River at Marble Canyon: Eric A. Rickart 2018 Arizona, Coconino County, Navajo Nation, vicinities of Bitter Springs and Marble Canyon 2 April (cont.) After some exploration, we set traps at a site about 10 km N of Bitter Springs a short distance to the east of US 89A (10.7 km N, 1.9 km E Bitter Springs, 1275 m). We then drove north on US 89 (towards Page) and set traps in an area with good pinyon-juniper woodland and rock outcrops (3.9 km N, 4.0 km E Bitter Springs) where we each set 40 traps. Finally, we drove back to US 89A and north to a point near Marble Canyon (1.3 km S, 2.5 km E Marble Canyon, 1130 m) where we set our final traps (Duke 40, me 30) and camped for the night. 3 April A partly cloudy, fairly mild night. In the 30 traps | set near camp, | caught 3 Peromyscus crinitus and 3 Chaetodipus intermedius. Those | set 10 km N of Bitter Springs took 1 P. amplus and 1 C. intermedius, and my line at the pinyon/juniper locality took 2 P. truei, 1 D. ordii, and 1 Neotoma Sp. (a very young animal — potentially devia, stephensi, or albibula). Duke took 1 P. truei at this last site; his traps at the other localities caught other animals. Captive animals were retained alive for preparation later in the day. We then drove up towards Page and took AZ rte. 98 southeast for several miles until the intersection of Navajo rte. 16 which we followed up to Navajo Mountain for our final night of trapping. @) Eric A. Rickart 2018 Utah: San Juan County, Navajo Nation, eastern flank of Navajo Mountain 3 April (cont.) We arrived at Navajo Mountain around mid-day, and fairly quickly found a good site in pinyon-juniper woodland slightly above 1800 m elevation. We spent a few hours preparing some specimens from the morning’s catch and placed other animals on dry ice. We then each set 80 Sherman traps (two lines each). | set one line in an area of pinyon, juniper and sage with sandy soil, and another in rocky habitat along the rim of a small canyon below our campsite. 4 April Clear and cold overnight. My 80 traps produced 1 P. crinitus, 1 P. maniculatus, 2 P. truei, and 2 large, long-tailed Peromyscus (likely P. boylii). Duke's traps caught the same assortment. We placed these on dry ice, packed up and left for our roundabout return to Salt Lake — back down into Arizona, up to Mexican Hat, Bluff (where we had lunch) Blanding, Monticello, Moab, then I-70 across to I-15 and home, arriving in Salt Lake around dusk. Frozen specimens from this trip were prepared over the next several days. Utah, Uintah County, Pelican Lake 17 April ee | left Salt Lake City yesterday morning along with Shannen Robson, Megan Mizuta, Emily Szalay, and Josh . We drove to Vernal arriving at 11:30 AM Eric A. Rickart 2018 and after eating Lunch went to the Vernal Fieldhouse of Natural History to A meet Steve Sroka, see their new facility, and consult with him and his staff regarding their collections in general and testing for arsenic preservatives in old vertebrate specimens. Midafternoon, we drove down to Pelican Lake where we intended to look for 13-lined ground squirrels — | captured one there nearly 40 years ago. Much of the open space in the Uinta Basin has been heavily impacted from development of oil over the past decades. We had a difficult time finding access to the western end of the lake where the BLM campground we were seeking is located. After more than an hour we eventually found the place and set up camp which was difficult given strong winds associated with an approaching cold front. We managed to set 64 traps (40 Shermans, 24 Victors) in the general area where | caught a ground squirrel long ago, finishing shortly before dusk. Although windy, temperatures were mild. While setting traps, Josh had picked up a very weathered skull of a prairie dog (Cynomys leucurus) — although these are common in general vicinity — particularly a bit further south on the Ouray NWR, I’ve seen only very old burrows in the general vicinity of Pelican Lake. We had strong winds all night under variable cloud cover. Quite cold at dawn, although well above freezing, still very windy with heavy overcast. Collectively, our traps took 21 animals — 10 Dipodomys ordii, 10 Peromysc us maniculatus, and 1 Reithrodontomys. The Victor traps were much more a Oat VO Sgt EAL LED : + 5 oe fi 4 BETO 3 . c ~ « - LEDS BRO : TEASE HBL — NA - MEE Eric A.

Weather conditions improved, with sunshine and diminished winds, so we left our traps in hopes of catching some ground squirrels. Around 11 AM clouds rolled in again and we decided to leave. So it is still a mystery as to whether /ctidomys still occurs at this place. We packed up and left here before noon, arriving in Salt Lake around 2 PM. All captures from this trip were frozen for later processing at the museum. rae 7 ‘ io « .< ~ > a / Me > r : a eet , =s p 2 ee ae a a os ‘ Bee eam a ‘ : @ Fert Ry tack 201 -——FT CGN 2 112. nen pec - teen * ——~ 6F° ot 2 : Scale Sie$e SRE aa ae isp Tene ala aera Ae ee aes Sager ue nt a E : ' a.
