FREQUENCY OF SAMPLING: All sites are sampled in autumn (early October to early November) and in spring (early March to early April).

All traps are checked early each morning, but after the end of the nocturnal activity period. All eight traplines are run during the same 4-day trapping period. The time of trapping in each season is set by the 14 core LTER traplines in that the seasonal burns are trapped directly before or after these traplines. The 14 core LTER traplines are trapped in the dark phase of the moon (no moon), so the amount of moonlight is variable due to cloud cover and moon phase on the seasonal fire traplines.

A battery-powered mustache clipper is used to clip a line of fur on each captured animals to indicate that that individuals has been captured in the current trapping period. The position clipped is as follows: on the lower back in a spring sampling period and upper back in an autumn sampling period. This method of marking allows an investigator to count an individual only once within a trapline during a trapping period. Further, three species of rodents (Peromyscus maniculatus, P. leucopus and Neotoma floridana) are marked with an ear tag (#1 monel fingerling tags) in each ear in addition to fur clipping to track movements of individuals among treatment units that are related to fire. Species, sex and reproductive condition of individual small mammals, trap station and any unusual features (e.g., the presence of ticks, fleas or bot fly larvae, variation in color pattern such as stars or blazes) are recorded at each capture of an individual in each trapping period. Body mass is recorded during the first capture of an individual on a trapline. Reproductive information recorded for males is the presence or absence of scrotal testes. Pregnancy is determined by palpation of the abdomen of females; no effort is made to assess the number of embryos. Presence or absence of conspicuous mammae also is recorded. Conspicuous mammae indicate that the female has been reproductively active and is nursing or has nursed offspring. Individuals are weighed to nearest 0.5 g for those weighing less than or equal to 50 g and nearest 1 g for those weighing greater than 50 g by using Pesola balances of an appropriate size.

FORM OF DATA OUTPUT: The total number of mammals captured by species by trapline forms the database CSM04. SUMMARY OF ALL CHANGES UP TO 2010 In autumn 1993, one trapline was established in four treatment units (FA, FB, WA and WB). Traplines in SpB and SuB were established earlier because the two traplines in SpB are the same permanent traplines established in autumn 1981 (west trapline is A and east trapline is B) for 004D and traplines in SuB are the same traplines established in autumn 1985 (west trapline is A and east trapline is B) for 010D. Previously, FA was a 4-year burn treatment (004E), FB (also designated initially as 004Ff) was a treatment unit that was unburned except in wet years (WC), WA was a treatment unit that was unburned for 3 consecutive years and then burned for 3 consecutive years (3U3BB) and WB was a 4-year burn treatment (004G, but note that the trapline is not the same as that established in 1981 because the Konza Prairie management removed the flags from these permanently marked stations in the interim). The treatment unit (SuB) has been burned biennially instead of annually because vegetation recovery after a July burn is not great enough to sustain a burn the following summer. In autumn 2007, we started ear-tagging deer mice in addition to the clipping of fur on 004F, SuB and WB to gain more information about how the seasonal fire treatments near the 004F (core LTER) traplines were affecting movements of this fire-positive species. Subsequently, we started ear-tagging deer mice on the remainder of the seasonal burns in spring 2008 as well as two other species, white-footed mice and eastern woodrats, to gain information about these two species relative to invasion of woody vegetation.
