INTRODUCTIONMany organisms have complex distributions, shaped by

geology, climate, and even anthropogenic disturbances (e.g. Dale et al., 2001; Broennimann et al., 2007). Un-derstanding the distribution of species is a focus of ecol-ogy, and fundamental to biogeography. The delineation of a species’ range is an important resource that can be utilized in ecological and evolutionary studies (Gui-san and Thuiller, 2005). For example, if a species has a fragmented distribution, isolated ‘populations’ may rep-resent unique lineages or Evolutionary Significant Units (Moritz, 1994; 2002). Once a species’ distribution is known, further studies can examine why it occurs in par-ticular areas and subsequently predict their occurrence (Gonzalez et al., 2011). Understanding distributions is important in ecological modeling (e.g. Guisan and Thuill-er, 2005; Thuiller et al., 2005), and if the boundaries of a species’ range used in analyses are not completely known, conservation assessments may be misrepresent-ed (Nelson et al., 1990; Graham et al., 2004). As the effects of climate change become more evident, a more complete knowledge of species distributions can contrib-ute to a more complete understanding of how a changing environment impacts wildlife (Berry et al., 2002). Northern latitudes have only been inhabitable by rep-

ABSTRACT - Recently a comprehensive overview of reptiles and amphibians in Michigan was pub-lished. Unfortunately, the distributions of the species represented were compiled before wide-spread accessibility to technological tools providing greater access to museum and historical records as well as citizen science efforts. To update the known ranges of Michigan herpetofauna, published literature, museum collections, and photographic vouchers submitted to an online da-tabase were examined and 339 new county and island records were added, updating the maps for 48 of Michigan’s 55 known species of reptiles and amphibians. I also present the first pub-lished list of Michigan amphibians that includes two new plethodontid salamanders, the Northern Dusky Salamander (Desmognathus fuscus) and Southern Two-lined Salamander (Eurycea cirri-gera). This paper serves as an example of the wealth of information available to scientists that may have previously been unobtainable, and can be used for the distribution of herpetofauna elsewhere.

tiles and amphibians since the end of the Pleistocene glaciation, which has presumably resulted in relatively low numbers of northern herpetofauna (e.g. Holman, 2001; 2004; 2012). As global temperatures continue to increase, many ectothermic species continue to disperse, expanding their distributions northwards (e.g. Holman, 2001; 2004; 2012). It is important to document any northward range expansions to monitor this phenome-non. The four major regional landscape ecosystems in the state of Michigan (Holman, 2004; 2012) have been heavily affected by past glaciation events (e.g. Holman, 2001; 2004; 2012), thus making it ideal for the study of changing distributions.Recently a much-needed overview of Michigan’s her-

petofauna was published (Holman, 2012). While other publications singled out specific taxa (i.e. snakes, Hol-man et al. 2006; turtles, Harding and Holman 1997; am-phibians, Harding and Holman 1992) or encompassed a larger region that includes Michigan (Harding 1997), Holman (2012) has written the first comprehensive work on Michigan herpetofauna in over 80 years (Ruthven et al., 1928). Holman’s book effectively summarizes many aspects of the biology of Michigan’s reptiles and am-phibians, including a paleontological perspective as well as distribution maps for each species. However, since

Holman’s text, more sources of information have be-come available due to technological advances. Much of the data used for present distribution modeling comes from museums and natural history collections (Ponder et al., 2001; Reutter et al., 2003; Araújo and Guisan, 2006). While there is a wealth of information that can be found in museum collections on species distributions or population trends (Boundy, 2004; 2005), voucher speci-mens are typically collected by biologists. Over the past decade, technology has afforded greater access to pub-lished literature records, and collaborative efforts such as VertNet (http://www.vertnet.org) have made records from museum collections more readily available. As a result, I used many of these technical resources to up-date the current geographic distributions of Michigan’s amphibians and reptiles, ultimately expanding on Hol-man’s recent publication and demonstrating how these sources can be useful in gathering additional information to characterize species distributions.

METHODSI performed literature searches (Google Scholar, Web

of Knowledge) and examined museum records (HerpNet (records are now combined with VertNet), Museum of Cultural and Natural History at Central Michigan Univer-sity (MCNH), University of Michigan’s Museum of Zoology (UMMZ)) for every reptile and amphibian species known to occur in Michigan. I also reviewed maps provided by the Michigan Natural Features Inventory (MNFI). Any questionable specimens (primarily on the basis of range) were verified by collection managers. I further consult-ed the Michigan Herp Atlas Project (MHA) accessible at (www.miherpatlas.org), where citizens are encouraged to report sightings of reptiles or amphibians in Michi-gan and can submit photographic vouchers. All photo-graphic vouchers used to fill in distributional gaps were personally verified by JGP. Any photograph that was not sufficient to identify the species and all non-vouchered reports were recorded with an ‘unverified’ designation. Such records are listed Appendix 4), but not included in distribution maps. Localities were identified to county or island.I adhere to the taxonomy used by Holman with the

following exceptions: 1) I use the genera Anaxyrus and Lithobates instead of Bufo and Rana (Crother, 2012); 2) I use Acris blanchardi instead of A. crepitans blanchardi for the Blanchard’s Cricket Frog (Gamble et al., 2008); 3) I use Pantherophis vulpinus for all foxsnakes in Mich-igan (Crother et al., 2011); 4) I omit subspecific names. Ambiguous identifications were not included in the case

of Gray and Cope’s Gray Treefrogs (Hyla chrysoscelis and H. versicolor), as these species cannot be differentiated by morphological characters; 5) I do not include a cat-egory for hybrid Ambystoma salamanders. Holman in-cludes two maps: one for the Blue-spotted Salamander (A. laterale) and the other for hybrids plus A. laterale. Hybrid Ambystoma do not occur across the entire range of A. laterale, and many older records fail to distinguish between the two, so I omitted this map.

RESULTSA comprehensive review of literature and museum da-

tabases yielded 269 unreported county records (Appen-dix 1). Also compiled are a list of herpetofaunal records on Michigan islands in the Great Lakes (Appendix 2). Among the 269 unreported literature and museum re-cords, 60 are supplemented by recent (2009-present) photographic vouchers from the MHA. In addition, anoth-er 70 MHA photographic vouchers represent new county records (Appendix 3), and an additional 74 unconfirmed MHA and other reports are also listed, but not includ-ed in the maps (Appendix 4). The combination of these findings altered the distribution maps from Holman 2012 for 48 of Michigan’s 55 species of herpetofauna (Appen-dix 5), including many records from literature, voucher specimens, and citizen science reports (Figure 1). Included among the updates are two species of pletho-

dontid salamanders, the Northern Dusky Salamander (Desmognathus fuscus; MSUM, voucher HE.14494) and the Southern Two-lined Salamander (Eurycea cirrigera; UMMZ, voucher UMFS 12185, originally listed as a North-ern Two-lined Salamander, E. bislineata), that have not been previously included in published contributions of Michigan herpetofauna (Ruthven et al., 1928; Harding and Holman, 1992; Harding, 1997; Holman, 2004; Hol-man, 2012). These specimens are known only from a single locality and may represent either recent introduc-tions or relict populations. Both species likely represent well established breeding populations (Mifsud, pers. comm.), and should continue to persist in Michigan if anthropogenic disturbance is limited.

DISCUSSIONThis contribution improves the understanding of herpe-

tofaunal distributions in Michigan. The updated ranges for all Michigan herpetofauna (Appendix 5) can assist with future biodiversity assessments, ecological model-ing, and species-specific studies. The plethora of sources used to compile these data also stands as an example of the amount of previously unavailable data present in museum collections and ‘grey’ literature. While older re-cords reflect where a species has been found, many lack recent verification. Regardless, over 20% of the liter-ature and museum records included here are support-ed by MHA photographic vouchers within the past five years. Given the uneven and sporadic sampling repre-sented by these photographic vouchers (e.g. some re-gions of the Upper Peninsula (UP) and northern Lower Peninsula do not have many records submitted to MHA), I suspect many more historic records are representative of extant populations. Any record whose legitimacy may be questioned and is not backed by a voucher speci-men is included in Appendix 4. Even with the addition of recent records, gaps in many species’ range maps re-main, indicating a need for further survey work. Those who encounter Michigan herpetofauna are encouraged to access The MHA (www.miherpatlas.org) and contribute any sightings, especially through photo documentation.

Similar ventures in other states, provinces or countries that utilize citizen science in this fashion are likewise worthy of support. This paper should be viewed as a supplement to the

range maps presented within Holman (2012), but should not be treated as an absolute list of Michigan herpe-tofaunal distributions. The data presented serve as an example of the wealth of information that has recently been made available by technological advances in infor-mation sharing, and may prove useful in any attempts to catalogue the distributions within a region or to docu-ment extensions of known species distributions.

cords of P. vulpinus on Lake Michigan islands (Bowen et al., 2007; MHA) indicate that this specimen may represent an accurate record.6 Seefelt et al. 2013c7 Blanchard 19378 Seefelt et al. 2013a

1 This record is listed in Ruthven et al. 1912 and 1928 as an unvouchered ‘report,’ in contrast to the majority of Ruthven’s records that were supported by museum vouchers.

2 This is well north of the previously accepted range for A. blanchardi (specimen originally listed as A. gryllus), so I report this record cautiously. However, F.N. Blanchard, the namesake of this species was considered an outstanding herpetologist in his day (Holman, 2012), so this may represent a legitimate specimen from a relict population (likely no longer extant).

3 This individual is outside of the commonly accepted range for A. blanchardi, and the specimen was unavailable for confirmation, so I report this record cautiously.

4 This record is outside of the commonly accepted range for A. blanchardi. The specimen has been verified by J. Harding, however it may have been inappropriately catalogued.

5 This is outside the known range of A. fowleri. Unfortunately, the specimen is no longer available for examination. This species is morphologically similar to A. americanus, which is well documented from Beaver Island so I report this record cautiously.

6 These specimens are backed by photographic vouchers, but were not identified by call, and therefore are considered unverified.7 This report is possibly a misidentification. There is no known evidence to suggest P. maculata is found on the mainland (Harding, pers. comm.).8 These records are listed as A. jeffersonianum, but A. jeffersonianum (Unisexual hybrid complex) and A. laterale were considered the same species as

recently as the 1970’s (Harding, pers. comm.), so these records may represent either one or both species. Unisexual Ambystoma are unverified in northern Michigan.

These include literature and museum specimens that may have incorrect identification or locality data as well as records submitted by the Michigan Herp Atlas (MHA), unverified by photographic vouchers. All abbreviations follow Appendix 1.


9 Gibbs et al. may be unreliable. In their 1905 paper they include Plethodon glutinosus, Carphophis amoenus, and Thamnophis radix, in their list of Michi-gan herpetofauna. To my knowledge, none of these three species has ever been collected in Michigan. Several of Gibbs et al.’s reports are supplemented by museum specimens or photographic vouchers (Michigan Herp Atlas), and most fall within the known ranges of these species. It should be noted that Gibbs incorrectly recorded the locality data on other specimens (N. Gilmore, pers. comm.), so it is plausible to consider that some of these are also inaccurate misidentified.

10 This represents a record of ‘E. bislineata’ that has been questioned (Mittleman, 1966). Given that both the Tuscola population and populations in Indiana have been identified as E. cirrigera (Kozak et al., 2006), I include it here as a potential historical record.

11 Previously, this specimen was believed to be a cataloguing error (Casper and Anton, 2008; Harding pers. comm.), but more recent records of P. vulpinus on Lake Michigan islands (Bowen et al., 2007; MHA) indicate that this specimen may represent an accurate record.

12 This report is from Stephen Ross, and is not explicitly available through the MHA.13 T. sauritus has never been confirmed in Michigan’s Upper Peninsula (UP). These records are photos without the resolution to unequivocally determine

identity beyond the genus level.14 These likely represent introduced specimens (Harding, pers. comm.), and are disjunct from the known range of G. insculpta.15 These specimens are reported by MNFI and are well out of the known range of T. carolina. This species is otherwise absent from the whole of the UP as

well as northern Wisconsin (Harding, 1997). These reports are not accompanied by vouchers, so I report these skeptically.16 This report by F. N. Blanchard is well north of the known range of T. carolina. As stated above, Blanchard is regarded as a prominent expert in Michigan

herpetology, but due to the proximity of this record to known T. carolina populations I report this record cautiously.

These include literature and museum specimens that may have incorrect identification or locality data as well as records submitted by the Michigan Herp Atlas (MHA), unverified by photographic vouchers.

Blanchard’s Cricket Frog (Acris blanchardi)

Three new records brings the total number of counties from which A. blanchardi has been found in Michi-gan to 30. This species occurs pre-dominantly in the southern third of Michigan, but may be found in some counties adjacent to its current range where suitable habitat is present.

Eastern American Toad(Anaxyrus americanus)

The distribution of A. americanus already encompassed all 83 counties and major islands in Michigan. There was no range extension added by this publication.

Fowler’s Toad (Anaxyrus fowleri)

Five new records brings the total number of counties from which A. fowleri has been found in Michigan to 27. This species occurs predom-inantly in the western half of the Lower Peninsula (LP) of Michigan, but may be found in some counties adjacent to its current range where suitable habitat is present.

Cope’s Gray Treefrog (Hyla chrysocelis)

One new record brings the to-tal number of counties from which H. chrysoscelis has been found in Michigan to 30. This species occurs across most of the Upper Peninsula (UP) and in the southern portion of the LP of Michigan. Since is it diffi-cult to identify apart from the Gray Treefrog (H. versicolor), it may oc-cur elsewhere throughout the state.

Appendix 5. The geographic distribution for all 55 species of reptiles and amphibians found in the state of Michigan. Localities are represented at the county level, but four main islands are also included (Beaver, Bois Blanc, Drummond, and Isle Royale), following the methods of Holman (2012). Counties recorded by Holman (2012) are in green, museum vouchers (orange), literature reports (gray) and photographic vouchers (yellow) are differentiated in the maps.

Gray Treefrog (Hyla versicolor)

Three new records (all from mu-seum specimens) brings the total number of counties from which H. versicolor has been found in Michigan to 78. This species occurs statewide and is only ‘missing’ from five coun-ties (Charlevoix, Delta, Gladwin, Ma-comb, Oceana). It is difficult to iden-tify apart from Cope’s Gray Treefrog (H. chrysoscelis), but may be present in all five of these counties.

American Bullfrog (Lithobates catesbeianus)

One new record brings the to-tal number of counties from which L. catesbeianus has been found in Michigan to 72. This species occurs statewide and is only ‘missing’ from 11 counties. It is found in counties adjacent to each of these and may be present in all of these counties where suitable habitat exists.

Green Frog (Lithobates clamitans)

The distribution of L. clamitans al-ready encompassed all 83 counties in Michigan. However, literature records also place L. clamitans on Drummond and Bois Blanc Islands in Lake Huron.

Pickerel Frog (Lithobates palustris)

Three new records brings to the to-tal number of counties from which L. palustris has been found in Michigan to 69. This species occurs statewide and is only ‘missing’ from 14 coun-ties. It is found in counties adjacent to each of these and may be present in all of these counties where suitable habitat exists.

Northern Leopard Frog (Lithobates pipiens)

The distribution of L. pipiens al-ready encompassed all 83 coun-ties in Michigan. However, museum specimens also place L. pipiens on Drummond and Bois Blanc Islands in Lake Huron. The only major is-land where L. pipiens has not been found is Isle Royale in Lake Supe-rior.

Mink Frog (Lithobates septentrionalis)

The distribution of L. septentri-onalis already encompassed all 15 counties in Michigan’s UP plus Isle Royale. No new records were add-ed by this publication. There is no indication that L. septentrionalis may be present in the LP, although it might be found on some Michigan islands (e.g. Drummond Island).

Wood Frog (Lithobates sylvaticus)

With one new record (Kalkaska Co.) L. sylvaticus occupies all coun-ties in Michigan. The distribution of L. sylvaticus already encompassed 82 counties in Michigan. Lithobates sylvaticus also occurs on all major islands except Drummond Island, where it may be found where suitable habitat is present.

Spring Peeper (Pseudacris crucifer)

The distribution of P. crucifer al-ready encompassed all 83 counties in Michigan. However, a literature re-cord also places P. crucifer on Drum-mond Island in Lake Huron. This species is now known from all major Michigan islands.

Appendix 5 (continued). The geographic distribution for all 55 species of reptiles and amphibians found in the state of Michigan. Lo-calities are represented at the county level, but four main islands are also included (Beaver, Bois Blanc, Drummond, and Isle Royale), following the methods of Holman (2012). Counties recorded by Holman (2012) are in green, museum vouchers (orange), literature reports (gray) and photographic vouchers (yellow) are differentiated in the maps.

Boreal Chorus Frog (Pseudacris maculata)

This species is only known from Isle Royale in Michigan. An unconfirmed report places P. maculata in Hough-ton County on the mainland UP, but there is no evidence to support that.

Western Chorus Frog (Pseudacris triseriata)

With one new record (Branch Co.) the distribution of P. triseriata en-compassed 77 counties in Michigan. This species occurs statewide and is only ‘missing’ from 6 counties. It is found in counties adjacent to each of these and may be present in all of these counties where suitable habitat exists.


Blue-spotted Salamander (Ambystoma laterale)

Ten new records brings the total number of counties from which A. laterale has been found in Michigan to 67. This species occurs statewide and is only ‘missing’ from 16 coun-ties. It is found in counties adjacent to each of these and may be pres-ent in all of these counties where suitable habitat exists.

Spotted Salamander (Ambystoma maculatum)

Thirteen new records brings the total number of counties from which A. maculatum has been found in Michigan to 59. This species occurs statewide and is only ‘missing’ from 24 counties. It is found in counties adjacent to most of these and may be present in all of these counties where suitable habitat exists.

Marbled Salamander (Ambystoma opacum)

This species was only known from three counties in southwest Michi-gan and had not been recorded in the state since 1989 (Holman 2012). However, a participant of the Mich-igan Herp Atlas discovered an A. opacum in Monroe County in south-eastern Michigan in 2015.

Small-mouthed Salamander (Ambystoma texanum)

This species is only known from five counties in southeast Michigan. This publication does not expand the range of A. texanum in Michigan, but it may occur in adjacent counties where suitable habitat is present.

Eastern Tiger Salamander (Ambystoma tigrinum)

Seven new records brings the total number of counties from which A. ti-grinum has been found in Michigan to 21. This species has been found in one county (Alger) in the UP and oc-cupies a patchy distribution through-out portions of the LP. It may occur in adjacent counties where suitable habitat is present.

Northern Dusky Salamander (Desmognathus fuscus)

This species is new to the herpeto-fauna of Michigan and is only known from a single site in one county (Tuscola). While there is some un-certainty as to whether D. fuscus is introduced or represents a relict pop-ulation in Michigan, there appears to a sustainable population (Mifsud, pers. comm.).

Southern Two-lined Salamander (Eurycea cirrigera)

This species is new to the herpeto-fauna of Michigan and is known from a single site in one county (Tuscola). It is uncertain whether E. cirrigera is introduced or represents a relict pop-ulation in Michigan, However, there is a sustainable population (Mifsud, pers. comm.). Initially, identified as the Northern Two-lined Salamander, E. bislineata, genetic work suggest-ed the population was in fact E. cirri-gera (Soderberg 2009).

Four-toed Salamander (Hemidactylium scutatum)

Fourteen new records brings the total number of counties from which H. scutatum has been found in Michigan to 50. This species occu-pies a patchy distribution statewide and is ‘missing’ from 33 counties. It is found in counties adjacent to each of these and may be present in all of these counties where suitable habitat exists.

Mudpuppy (Necturus maculosus)

Six new records brings the total number of counties from which N. maculosus has been found in Michi-gan to 66. This species is only ‘miss-ing’ from 17 counties. It is found in counties adjacent to each of these and may be present in all counties. It is found on some islands in the Great Lakes, but has not been recorded from Beaver or Bois Blanc Islands.

Eastern Newt (Notophthalmus viridescens)

Four new records brings the total number of counties from which N. vir-idescens has been found in Michigan to 66. This species occurs statewide and is only ‘missing’ from 17 coun-ties. It is found in counties adjacent to each of these and may be present in all of these counties where suitable habitat exists.

20. 22. 24.



Eastern Red-backed Salamander(Plethodon cinereus)

With three new county records plus Drummond Island (all listed in the text of Holman 2012), P. cinereus has been recorded in every county and major island in the state of Michigan.

Western Lesser Siren (Siren intermedia)

This species is only known from two counties in southwest Michigan and has not been recorded in the state since 1961 (Holman 2012). This pub-lication does not expand the range of S. intermedia in Michigan, and it is unknown if it still occurs in the state.

Five-lined Skink (Plestiodon fasciatus)

Eight new records brings the total number of counties from which P. fasciatus has been found in Michi-gan to 44. This species occupies a patchy distribution statewide and is ‘missing’ from 39 counties. It is found in counties adjacent to most of these and may be present in all of these counties where suitable habi-tat exists, at least in the LP. In the UP, P. fasciatus has only been found in the central counties.

Six-lined Racerunner (Aspidoscelis sexlineatus)

This species only known from a single site in one county (Tuscola). While there is some uncertainty as to whether A. sexlineatus is intro-duced or represents a relict popu-lation in Michigan, there appears to a sustainable population. This pub-lication does not expand the range of A. sexlineatus.

Kirtland’s Snake (Clonophis kirtlandi)

This species is only known from eight counties in southern Michigan. This publication does not expand the range of C. kirtlandi in Michigan. It may occur in adjacent counties where suitable habitat is present.

North American Racer (Coluber constrictor)

Seven new records brings the total number of counties from which C. constrictor has been found in Mich-igan to 45. This species is found in one county in the UP (Menominee) and throughout the southern and western portions of the LP. It may oc-cur in adjacent counties where suit-able habitat is present.

25. 27. 29.

26. 28. 30.



Ring-necked Snake (Diadophis punctatus)

Three new records (all literature) brings to the total number of counties from which D. punctatus has been found in Michigan to 48. This species is found throughout the western and northern LP, and UP (Menominee) with a fragmented distribution in the southern LP. It may occur in adjacent counties where suitable habitat is present.

Eastern Hog-nosed Snake(Heterodon platirhinos)

Ten new records brings the total number of counties from which H. platirhinos has been found in Mich-igan to 53. This species occupies a fragmented distribution throughout the LP, and is also found in one coun-ty in the UP (Menominee). It may oc-cur in adjacent counties where suit-able habitat is present.

Eastern Milksnake(Lampropeltis triangulum)

Six new records brings the total number of counties from which L. triangulum has been found in Mich-igan to 64. This species is found throughout the LP, and two counties in the UP (Mackinac and Marquette). It is ‘missing’ from only six coun-ties in the LP, and has been found in counties adjacent to all of these. It may be found throughout the LP where suitable habitat is present.

Plain-bellied Watersnake (Nerodia erythrogaster)

Two new records brings the total number of counties from which N. erythrogaster has been found in Michigan to nine. This species occurs in the southern portion of the LP of Michigan. This species is protect-ed in Michigan and is not common, but may occur in adjacent counties where suitable habitat is present.

Northern Watersnake(Nerodia sipedon)

Five new records brings the total number of counties from which N. sipedon has been found in Michigan to 76. This species is found through-out the LP, only absent from three counties (Bay, Sanilac, Tuscola), and is also found throughout the UP ex-cept in a cluster of five counties in the western portion It may occur in adjacent counties where suitable habitat is present.

Smooth Greensnake(Opheodrys vernalis)

Nine new records brings the total number of counties from which O. vernalis has been found in Michigan to 58. This species is found through-out the UP and northern LP with a scattered distribution in the southern LP. It may occur in adjacent counties where suitable habitat is present.

Gray Ratsnake(Pantherophis spiloides)

Two new records (both photo vouch-ers) brings the total number of coun-ties from which P. spiloides has been found in Michigan to 25. This species is found the southern LP, although one new record is in Montmorency County, far north of its known dis-tribution. It may occur in adjacent counties in southern Michigan where suitable habitat is present.

Eastern Foxsnake(Pantherophis vulpinus)

One new record (photo voucher) brings the total number of counties from which P. vulpinus has been found in Michigan to 21. This species is found in western/central UP and southeastern LP. It may occur in adja-cent counties in southern Michigan where suitable habitat is present. Previously, P. vulpinus in Michigan has been considered as two species, but recent work (Crother et al., 2011) suggested that all Michigan foxsnake populations belong to P. vulpinus.

Queen Snake(Regina septemvittata)

Two new records (museum spec-imens) brings the total number of counties from which R. septemvitta-ta has been found in Michigan to 18. This species occupies a fragmented distribution in the LP and may occur in adjacent counties where suitable habitat is present.

Eastern Massasauga(Sistrurus catenatus)

Five new records brings the total number of counties from which S. catenatus has been found in Mich-igan to 53. This species occupies a fragmented distribution in the LP and may occur in adjacent counties where suitable habitat is present. S. cate-natus is listed as endangered in the State of Michigan. Any observations should be reported to the Michigan Department of Natural Resources.

Dekay’s Brownsnake (Storeria dekayi)

Seven new records brings the total number of counties from which S. dekayi has been found in Michigan to 66. This species occupies a fragment-ed distribution in the UP and is found in most counties in the LP. Storeria dekayi may occur in all counties in the LP where suitable habitat is pres-ent.

Red-bellied Snake(Storeria occipitomaculata)

Sixteen new records brings the to-tal number of counties from which S. occipitomaculata has been found in Michigan to 66 plus all major islands. This species is found throughout the UP and most counties in the LP. Storeria occipitomaculata may occur in all counties in the LP where suit-able habitat is present, although it is notably absent in the southernmost tier of counties.

Butler’s Gartersnake(Thamnophis butleri)

Four new records brings the total number of counties from which T. butleri has been found in Michigan to 28. This species is found only in the eastern and central portions of the LP. Thamnophis butleri may occur in adjacent counties where suitable habitat is present.

Northern Ribbonsnake(Thamnophis sauritus)

Eight new records brings the total number of counties from which T. sauritus has been found in Michigan to 60. This species is found through-out the LP in all but eight counties where it may be found where suit-able habitat is present. Thamnophis sauritus is also known from all major islands in Michigan, but is unverified from the UP.

Eastern Gartersnake(Thamnophis sirtalis)

Three new records (from the text of Holman 2012) brings the total number of counties from which T. sirtalis has been found in Michigan to 83. The range of this species en-compasses every county and major island in Michigan.

Spiny Softshell(Apalone spinifera)

Eleven new records brings the to-tal number of counties from which A. spinifera has been found in Mich-igan to 34. This species is found consistently in the southern LP and occupies a fragmented distribution in the central portion of the state. Apalone spinifera may be present in additional counties where suitable habitat is present.

Eastern Snapping Turtle(Chelydra serpentina)

Twelve new records brings the to-tal number of counties from which C. serpentina has been found in Mich-igan to 83 as predicted by Holman (2012). The range of this species en-compasses every county and in ad-dition to some islands of the Beaver Archipelago in Lake Michigan.

Painted Turtle(Chrysemys picta)

Nine new records brings the total number of counties from which C. picta has been found in Michigan to 83 as predicted by Holman (2012). The range of this species encompass-es every county and major island in Michigan with the exception of Bois Blanc Island in Lake Huron.

43. 45. 47.

44. 46. 48.



Spotted Turtle(Clemmys guttata)

Four new records brings the total number of counties from which C. guttata has been found in Michigan to 42. This species is found consistent-ly in the southern LP and occupies a fragmented distribution in the central portion of the state. Clemmys gutta-ta may be present in additional coun-ties where suitable habitat is present, but is protected in the state of Michi-gan and may prove difficult to find at additional localities.

Blanding’s Turtle(Emydoidea blandingii)

Five new records brings the total number of counties from which E. blandingii has been found in Michigan to 73. This species is found consis-tently in the LP and central UP. Em-ydoidea blandingii may be present in additional counties where suitable habitat is present, but is protected in the state of Michigan and may prove difficult to find at additional localities.

Northern Map Turtle(Graptemys geographica)

Seventeen new records brings the total number of counties from which G. geographica has been found in Michigan to 52. The new records move the range in the LP farther north than previously recorded. This species is found consistently in the LP and two counties in central UP. Graptemys geographica may be present in additional counties where suitable habitat is present.

Wood Turtle(Glyptemys insculpta)

Three new records brings the total number of counties from which G. ins-culpta has been found in Michigan to 48. This species is found consistently in the UP and northern LP, but it ab-sent from the southern portions of the state. G. insculpta may be present in additional counties where suitable habitat is present, but is protected in the state of Michigan and may prove difficult to find at additional localities.

Eastern Musk Turtle(Sternotherus odoratus)

Four new records brings the total number of counties from which S. odoratus has been found in Michigan to 31. This species is found predom-inantly in the southern LP, but has been recorded in a few northern LP populations and may be present in additional counties where suitable habitat is present.

Eastern Box Turtle(Terrapene carolina)

Four new records brings the total number of counties from which T. carolina has been found in Michigan to 38. This species is found predom-inantly in the southern and western counties in the LP. Terrapene carolina may be present in additional counties where suitable habitat is present, but is protected in the state of Michigan and may prove difficult to find at ad-ditional localities.

49. 51. 53.

50. 52. 54.



Pond Slider(Trachemys scripta)

Five new records (all photo-vouch-ers) brings the total number of coun-ties from which T. scripta has been found in Michigan to 11 BA). This species is found predominantly in the southeastern Michigan, but is nonna-tive to the state, and may continue to spread northward as it has proved to be a successful invasive species in other areas (Thomas et al. 2010).
