Abstract
Eastern collared lizards (Crotophytus collaris collaris) were a Missouri state endangered species when this study began in 1982 due to massive local extinction on glades in the Ozarks in central North America. Translocation coupled with glade restoration was initiated in the 1980’s, including reintroductions starting in 1984 on Stegall Mountain in southern Missouri. The translocated populations underwent three distinct demographic phases: 1) an isolate phase with no net growth in population size, no colonization of nearby glades, and almost no dispersal among populations, 2) a colonizing phase of high dispersal, colonization of new glades, and population growth that started with the onset of prescribed woodland burning, and 3) a stable metapopulation phase established by 2000 on Stegall Mountain in which the number of occupied glades, total population size, and measures of genetic variation were roughly constant. The data in this dryad submission are association with a paper (2023) in Animal Conservation that used these data to infer the age of 1162 marked individuals on the basis of distinct color phases and to assign age-probabilities to 391 marked individuals first captured with adult coloration based on time-of-capture within the field season and snout-vent length, as calibrated from following 529 individuals first captured as hatchlings. Age structure differed significantly between phases. The isolate phase was characterized by an old age structure. The colonization phase had a younger age structure and much more recruitment. The stable metapopulation phase had an intermediate age structure. These dynamic age structure attributes show that species cannot be regarded as static units, and ignoring this dynamism can result in poor conservation practice. These results also validate age-structure as a monitoring device for a conservation program and a tool to identify significant shifts in the environment or management that have a conservation impact, in this case prescribed woodland burning. Other papers on these collared lizard populations also make use of these data.

Description of the data and file structure
Eastern collared lizards (Crotophytus collaris collaris) were a Missouri state endangered species when this study began in 1982 due to massive local extinction on glades in the Ozarks in central North America. Translocation coupled with glade restoration was initiated in the 1980’s, including reintroductions starting in 1984 on Stegall Mountain in southern Missouri. Under fire management, the lizards expanded to other glades on Stegall Mountain and nearby mountains. We have followed these populations with mark/recapture techniques, morphological measurements, and genetic surveys of micro-satellite loci.
Files and variables
File: Peck_Ranch_Collared_Lizard_Data.xlsx
Description: This is an Excel file giving the capture/recapture data on collared lizard populations translocated to the Peck Ranch Conservation Area between 1984 and 1989 and their subsequent fate through 2014.
Variables
-
1. Variable List in Excel File:
1. Column A gives the year of capture or recapture of a lizard
2. Column B gives the date of capture or recapture of a lizard
3. Columns C and D give the location of capture or recapture of a lizard
Column C gives the glade of capture/recapture (see the glade maps & waypoints text) Column D gives a section of the glade of capture/recapture (see the glade maps)4. Column E gives the identity number (ID#) given to a lizard upon capture through toe-clipping.
Sometimes lizards lose toes naturally, which can create ambiguities, which are noted. Because this study lasted so long and the number of available toe clips is finite, some numbers had to be re-used. When this occurred, the a second number is given after a decimal point to indicate the re-use of that number. For example,40.1 and 40.2 are two different lizards, each using the toe clip number of 40. Such re-uses are always separated by a period of many years in which the lizard with the original number has not been observed or recaptured.5. Column F gives the sex of the lizard. F=Female, M=Mal, H=Hatchling of undetermined sex.
Sometimes an initial assessment of sex of hatchlings is made and indicated by H/F or H/M. These assessments were found not be very accurate.6. Column G gives details about the capture: founder, new adult (New A), new yearling (New Y
or New J), new hatchling (New H), and recapture with previous year of capture/recapture indicated (YearR).7. Column H gives the snout-vent length in millimeters, SVL(mm).
8. Column I gives the tail length in millimeters, tail(mm).
9. Column J gives the distance in millimeters between the two knees of the hindlegs when
oriented in a straight line, Legs(mm).10. Column K gives the weight in grams, Wt.(gm).
11. Column L is for notes taken at the time of capture
2. Number of cases/rows:
Row 1 is a header row for the columns
Rows 2 through 6746 give the variable information for each capture or recapture or glade survey.
3. Missing or non-applicable entries:
Missing data is indicated by “null”. In the notes column L, “null” is used to indicate that a note was not entered.
Not-applicable is indicated by “n/a”. Some glades were subdivided into sections while others were not (see map files).
For glades that were not subdivided, "n/a" is inserted in the section column. Sometimes no captures occurred on a glade, so "n/a" is inserted for all capture related entries. To avoid recapturing the same individuals multiple times on a glade visit, the lizard's ID number was painted on its back with water-soluble paint. These marks were temporary, but were often visible for a week, unless the skin was shed. Captures were often not attempted for animals that could be sight-identified through their painted number, so "n/a" was entered for columns H and through K. Sometimes the lizard was recaptured, but not all the measurements were taken if the lizard had already been measured a short time ago.

Data was derived from the following sources:
- The Templeton laboratory at Washington University in St. Louis
The raw information in this file was written down in field notebooks by the collector at the time of capture. All these notebooks are in the procession of Alan Templeton. Alan Templeton assembled all of these data from the field notebooks into this Excel file. Typically, the field data were entered into the Excel file the evening after a day of collection. All entries were double-checked for accuracy of transcription from the field notebooks.
The maps were made by overlaying aerial photographs with extensive ground-trothing upon standard topographic maps from the USGS.
Latitude and longitude of central glade positions were taken with a handheld Garmin GPS unit and then downloaded directly from the device.
The information in the genetic data file was produced by Jennifer Neuwald, now at Colorado State University. It gives the genotypes at six microsatellite loci for the lizards captured on Thorny Mountain.
The data includes six files:
PECK RANCH COLLARED LIZARD DATA, an Excel file giving the capture/recapture data on collared lizard populations translocated to the Peck Ranch Conservation Area between 1984 and 1989 and their subsequent fate through 2014.
