Diagnosis:
 DANGEROUSLY VENOMOUS (a threat to life or limb): Largest native rattlesnake in Kansas. Heat-sensing pit on each side of the head between and slightly below eye and nostril; large rattle at end of a jet black tail; small scales covering most of top of the head with one large scale over each eye; a pattern of 18–33 dark bands or chevrons on the back. Head and body vary from pinkish-gray to yellowish-brown; indistinct rusty, reddish stripe often runs down the middle of the back. Belly grayish white. Young look like miniature adults.
This is a large, stout-bodied snake that can obtain lengths of five feet or more. Adults normally grow 900-1,520 mm (36-60 inches) in total length. The largest specimen from Kansas is a female (KU 1645) from Douglas County with a total length of 1,613 mm (63½ inches, including rattle) collected by Charles D. Bunker and G. I. Adams in June 1899. The maximum length throughout the range is 74½ inches (Conant and Collins, 1998). The maximum weight for a Kansas specimen is 2,386 grams (5 pounds, 4 ounces).
Distribution:
 The Timber Rattlesnake is known from the Marais des Cygnes, Kansas, and Missouri drainage basins. It enters Kansas from Oklahoma in the Cross Timbers but is conspicuously absent from the Neosho River basin.
The observation at Pittsburg, Crawford County, was reported in the Pittsburg Morning Sun (newspaper) on Wednesday 29 August 2001. The snake was discovered at 11 am basking on the pavement near the south entrance to the Bath-Naylor Funeral Home. The article also stated that this is the third time in 17 years that a rattlesnake has been found inside the Pittsburg City Limits. This record is questionable and additional reports (or preferably specimen[s]) are desired.

Natural History:
 Active by day during spring and fall in rugged terrain along heavily vegetated, rocky outcrops on partially forested hillsides; in summer, they move to open sparsely wooded meadows and hillsides. Prowls at night during hot weather. Five to 14 young per litter are born in August, September, and October. Feeds on small mammals, as well as on smaller snakes.
Timber Rattlesnakes breed in the spring or fall (July or August) and are sexually mature at 7 to 12 years of age. Males may "combat" with other males. The two snakes intertwine the posterior portion of their bodies together while they raise the anterior half into the air and try to push each other to the ground. The successful male will go on to breed with a female. The females may breed every 2 to 4 years (3 is the most common interval) and may spend their gestation period near the hibernation dens. They do not eat during this period, but they spend much of their time basking. They are ovoviviparous and give birth to about a half-dozen young inside individual membranes. The young are born in August or September and are 10 to 13 inches in length.
Occurrence Activity:
 White dates indicate there is at least a single recorded occurrence on that date. The darker blue a date is, the greater the relative number of observations for that date.
Remarks:
 First reported from Kansas by Cope (1859) based on a specimen from "Kansas" collected by Fort Riley surgeon William A. Hammond. Yarrow (1882) lists a specimen (USNM 4621) from "Kansas" collected by U.S. Arm Topographical Engineers Captain J. H. Simpson collected in 1858. This is the earliest existing specimen from Kansas.
Reportedly declining throughout portions of its former range elsewhere, this large, shy snake is generally doing well where it occurs in Kansas. While individually well-camouflaged it is difficult for populations of this large snake with prominent rattles to escape detection, and it is generally a well-known snake where it occurs. Fitch (1984) postulated that prior to settlement, Timber Rattlesnakes were not common and that with greater control of fires and the concomitant increase in forests their populations have increased. 
In rural areas the Timber Rattlesnake is abundant. Populations have probably changed little in the past 50 years. In urban areas, the greatest threat it faces is habitat conversion for development. In these areas (Wyandotte and Johnson counties specifically) populations are certainly declining.
Enough data exists to show that many populations of Timber Rattlesnakes still persist in less developed portions of Johnson and Wyandotte counties. Local extinctions and fragmentation have already occurred, and more is inevitable.
The Timber Rattlesnake was listed as a Kansas SINC species in 1993.

Lieutenant Abert left Fort Leavenworth on 27 June 1846 en route to San Diego, California.
By 8 July they had reached Turkey Creek in Marion County, where he remarked "The men killed several rattlesnakes near our camp, and one a grey snake, marked with a row of blackish spots along the back; it is said never to exceed two feet in length, and is called the grey rattlesnake."
On 11 July they had reach Cow Creek in Rice County and Abert noted "As our wagons moved along the road, the lizards (Lacerta lineatus) [Aspidoscelis sexlineata] were darting rapidly along the ruts in front of it, anxious to escape being crushed. The common land turtle (Testudo clausa) [Terrepene ornata] were also very abundant."
On 14 July they had reached Pawnee Rock (Barton County) where he wrote, "This morning Laing brought me a very large toad, (Rana musica) [currently a synonym for Anaxyrus terrestris but likely referring to A. woodhousii far exceeding any I ever before have seen."
On 15 July, and still at Pawnee Rock he wrote "To-day we saw several large white cranes with black-tipped wings; (Grus americanus) and Laing killed me some rattlesnakes, (Crotalus horridus) [not local] and several prairie snakes."
On 18 July they were moving along the Arkansas River west of Pawnee Rock and noted "The ruts of the road were full of little lizards, sunning themselves; as we approached they would dart briskly away, manifestly disinclined to play the part of devotees to Juggernaut."

Describes all snake species reported from Kansas, considering doubtful those species that the author has not encountered himself. This list contains twenty-nine valid species. Collections examined included State University (KU), State House, Washburn College (WU), Ottawa University, State Normal School (ESU), State Agricultural College (KSU), and several high schools in Kansas. Examined the material available to Mozley (1878) and determined that of the thirty-three species listed, only twenty-three species were valid currently. And that Cragin's (1880) list of thirty-two species included eight specimens on the authority of Mozley that this author could not verify in any collection.

Accounts on forty species known from the vicinity of Manhattan, Riley County, Kansas. There have been several scientific names changes since publication, which is understandable... however, some usages cannot be explained by subsequent taxonomic reappraisals(e.g.  Gastrophryne carolinensis for Gastrophryne olivacea). The writer lists Eumeces (=Plestiodon) obsoletus and E. guttulatus yet correctly reasoning that the latter is the young of the former. Within the account of Tantilla gracilis (a common form) the writer mentions that T. nigriceps was reported from Riley County by Branson (1904) but that the specimens at Kansas State were absent at the time of publication. The Prairie Rattlesnake (Crotalus viridis) was first reported from Riley County by Branson (1904) and is reported by the writer based on a specimen in the museum at Kansas State University by Professor E. A. Popenoe. The Prairie Rattlesnake is not currently native to Riley County, and closest reliable localities are 150 to the west.

Report on certain Kansas specimens housed in the collection at what is now Pittsburg State University. Included are several species of dubious status today, including Cryptobranchus alleganiensis from the Neosho and Spring rivers (the only specimens from those significant drainages ever documented), Ambystoma maculatum from just north of Pittsburg, Crawford County, Heterodon nasicus from Crawford County, Opheodrys vernalis from Crawford County, Sonora episcopa from Crawford County, Agkistrodon piscivorus from Cherokee County, Crotalus atrox from Crawford County, and Crotalus viridis from Crawford County. They report several significant range extensions including Kinosternon flavescens from Turkey Creek in southeast Cherokee County, Graptemys geographica from just north of Pittsburg, Crotaphytus collaris from near Columbus, Cherokee County, Sceloporus consobrinus from just north of Pittsburg, Phrynosoma cornutum from Cherokee and Crawford counties, Heterodon platirhinos from Cherokee and Crawford counties, Haldea striatula from Crawford County, Sistrurus tergeminus from Crawford County, and a 402 lb Macrochelys temminckii in Cherokee County from just east of Chetopa (Labette County). They allude to the potential for Anaxyrus fowleri to occur in southeast Kansas and for native populations of Crotalus atrox in south central Kansas (in part from the disclosure that John R. Breukelman [then of ESU] had obtained three specimens in Woods County Oklahoma, 3/4 of a mile south of the Kansas line). None of the specimens the paper was based on, exist today.
