Settlement Trees, Illinois Level 0, 1804-1849

DOI PLACE HOLDER

Abstract:

We provide a Level 0 record of trees in Illinois transcribed from Public Land Surveys conducted by surveyors from the General Land Office of the United States in the 1800s. Posts were set every half mile in townships that were typically 6 miles by 6 miles square. Surveyors recorded details about the one to four trees closest (but typically recorded information for the two closest trees) to the posts and included information about the tree name (taxonomic specificity ranged by surveyor), tree diameter (inches), and distance and bearing from the post. Our records include the tree information and the location of the posts from which the tree information came from. For the msb-paleon.28.0 package, these Level 0 tree data were aggregated to the 8km grid resolution Level 1 product (see msb-paleon.26 package). That product was then statistically smoothed using a statistical model that accounts for zero-inflated continuous data with smoothing based on generalized additive modeling techniques and approximate Bayesian uncertainty estimates for the Level 2 products estimating aboveground biomass (msb-paleon.23), density (msb-paleon.24), and basal area (msb-paleon.25). The data processing steps and associated code are available in the GitHub repository: https://github.com/PalEON-Project/PLS_products.

These products are used in the manuscript, Paciorek et al., 2021, The forests of the midwestern United States at Euro-American settlement: spatial and physical structure based on contemporaneous survey data. PLoS ONE 16(2):e0246473 (https://doi.org/10.1371/journal.pone.0246473).

Definition:

The township, township direction, range, range direction and primemeridian concatenated for each corner

The x –coordinates in meters for the location of the corner the tree data is associated with. These coordinates come from the NAD 1983 Great Lakes and St. Lawrence Albers (epsg:3175) projection.

The y –coordinates in meters for the location of the corner the tree data is associated with. These coordinates come from the NAD 1983 Great Lakes and St. Lawrence Albers (epsg:3175) projection.

This is the version number as the data was entered into Notre Dame's data entry system and then subsequently georeferenced. The individual corner and tree entries have been entered into Notre Dame's database starting in 2013 and go up to version 2.0, which was renamed version 1.0 when it was archived in NIS as package msb-paleon.28. Data entry for Illinois is ongoing so additional data will be added in the future until data from all townships have been entered.

Unique identification number given each entry when entered into ND’s MySQL (values range from 421460-714173)or Qualtrics (values start with "R", followed by a random alpha-numeric value, e.g., R_3iEDyGzsS632hUU) databases.

The date and time when the entry was entered or modified. When making the shapefile for GIS, this data does not convert, so many of these entries are removed here. If you need this information, Jody Peters can get it from Notre Dame's MySQL or Qualtrics database.

Initials/name of person who entered the data. Depending on the data entry system sometimes the names match the Notre Dame id system and sometimes they are the students name.

Name of surveyor from PLS notes. 99999 represents missing name

PLS volume data came from. Illinois has volume numbers (unlike Indiana which does not).

Page in the PLS notes data came from

Year of PLS survey

State (IL) the survey was conducted in. There are some corners in townships 10N11W2, 9N11W2, and 8N11W2 on the border with Indiana where notes may be from Indiana records, but are physically located within Illinois. The state listed in this column are where the corners are physically located. The state where the notes were read from are listed in the General Notes section.

The county the township is located. Hubtack is the resource Notre Dame uses to get PLS records for Illinois and since our database was set up to first record data from Illinois, this column is still labeled as Hubtack_county.

Baseline number (1-4) of the township. These were entered the same as the prime meridian values so may not actually be the true baseline numbers.

Prime meridian number (1-4) of the township

The township number

Township direction (N or S)

Range number of the township

Range direction (E or W)

One of two interior sections the surveyor was traveling between (values range from 1-36).

The other of the two interior sections the survey was traveling between

The southern (31, 32, 33, 34, 35, ,36) or eastern (1, 12, 13, 24, 25, 36) township boundary section numbers. The name is a bit misleading because these sections are on the boundaries not on the interior of the township.

The township border that was entered. Typically the data was only entered for the southern and eastern borders for each township, not the northern and western borders.

Notre Dame has a standard numbering system for the 1/4 and section corners in a township. You can find the map here: https://www.dropbox.com/s/r0x3c9bf9vci02v/PLS%20Township%20Grid%20PalEON.pdf?dl=0. The refcorner is the corner ID number from this map that the surveyors were traveling from

The direction the surveyors were traveling (E, W, N, S)

This denotes whether the surveyors were traveling over that portion of the township a second time. Y (yes) is used in cases when the surveyors have set a temporary post going one direction on a random line (typically when they travel east or west) and have come back on a true line and set the actual post and recorded trees. N (no) is used when the surveyors travel over a line only once (typically when they travel north or south).

The chains the section or 1/4 section corners were recorded at. Typically corners are 80.00 chains (or very close to 80) and 1/4 section corners are 40.00 chains (or very close to 40).

Labels are (¼) Section (i.e., corners set at the ½ mile, 40 chains), Section (i.e., points on the mile, 80 chains) or Township (i.e., the most NE, SE, and SW corners on the Township which are corners that could be found in adjacent townships). The township corners are labeled 100100, 700100, or 700700 on the corner map linked in the reforner description above.

The corner ID where the corner posts were set. These ID numbers come from the corner map linked in the refcorner description above.

This is the species for the first tree the surveyor recorded. The species name comes from a drop down list of options in the data entry form. DO NOT USE THIS OR THE SPECIES TO ASSESS TREE SPECIES, INSTEAD USE THE VERBATIM, LEVEL 1 OR LEVEL 3 TREE NAMES.

2 letter abbreviation used for the first tree the surveyor recorded. These typically correspond with the species codes used by David Mladenoff from the University of Wisconsin, Madison. DO NOT USE THIS OR THE SPECIES TO ASSESS TREE SPECIES, INSTEAD USE THE VERBATIM, LEVEL 1 OR LEVEL 3 TREE NAMES.

This is the tree name as written in the PLS notes for the first tree listed in the notes.

Level 1 tree names. These are the names written verbatim, unless the verbatim entries have a ditto (also written do or ", etc). For example, if the verbatim notes say “ditto" and the previous tree surveyed was a beech, then L1_tree1 will be beech.

Level 3 tree names. These are standardized tree names that convert the Level 1 names to a genera level common name. e.g., Level 1 = White Oak, Level 3 = Oak. The conversion files can be found in the GitHub repository: https://github.com/PalEON-Project/PLS_products

Diameter in inches of the first tree the surveyor recorded. NOTE: there are some trees that have very large diameters (greater than 60 in). If you have a question about the size of the tree, check the "fixed" column to see if the notes have been double checked.

First bearing direction of the first tree the surveyor recorded (N, S, E, W – typically N or S unless a tree was set on the E or W cardinal direction).

Bearing degrees of the first tree the surveyor recorded (0-90; NOTE: degrees greater than 90 were double checked by Jody - see the notes for information about these entries).

The second bearing direction of the first tree the surveyor recorded (E, W).

Although this says “chains” this is the distance in links (NOT chains) from the post to the first tree the surveyor recorded.

This is the species for the second tree the surveyor recorded. The species name comes from a drop down list of options in the data entry form. DO NOT USE THIS OR THE SPECIES TO ASSESS TREE SPECIES, INSTEAD USE THE VERBATIM, LEVEL 1 OR LEVEL 3 TREE NAMES.

When Notre Dame had used the GLO form/MySQL database to enter data, this had been the letter abbreviations regarding ecotypes. For example – G = grove, L = lake, P = prairie. When we switched to using the Qualtrics form to enter data, the ecotype names were no longer abbreviated. Although this wasn’t used extensively, there are some corners where students noted this. Corners in townships that were part of the Kankakee project are the most likely to have entries in this column with a focus on water notes. When we switched to entering data using the Qualtrics form in Fall 2017, ecotypes was used to describe corners with water/wet features.

Verbatim notes regarding the ecotype abbreviation

Another option to add more ecotype information

Attribute that characterized if corner post was set in Water or a Wet location. Water = a perpetually wet spot in a lake, creek, river, marsh, swamp, etc. Wet = a location that was noted as seasonally wet. See the generalnotes, features or ecotype columns to see why these corners were classified as water or wet.

A “Yes” entry means there was no data available for this corner (data was missing from the notes because the page was missing or the entry was just not written in. See the description in the general notes about why there was no data)

A “yes” entry means there was no tree listed at this corner either because it was water/wet or was in prairie. See the description in the generalnotes, ecotype or features to see why there was no tree.

Attribute for entering notes about non-ecological features. Examples include Post, Post in Mound, Road, House, etc. This was mainly used to note when there are no trees and surveyor sets a “post in mound”.

Verbatim description of the features

Notes about the type of timber for the past mile or 1/2 mile survyed getting to this corner. Students entered this data early in the data entry process, but stopped doing it around the summer of 2013.

Notes about the understory vegetation for the past mile or 1/2 mile surveyed gettin to this corner. Students entered this data early in the data entry process, but stopped doing it around the summer of 2013.

Drop down list of general landnote features. The surveyors often provided a general description of the land for the preceding half mile (notes are included with the tree information for the 1/4 section corner at 40 chains) or mile (notes are included with the tree information for the section corner at 80 chains). Notes often included information about the potential for cultivation or natural resources. NOTE: this description is for the land for the last half to one mile, so it does not necessarily pertain to the land specifically at the post. For example, there could be water features in the 1/2 mile surveyed, but that doesn't mean the post is set in water.

Verbatim land notes. This is used when the notes are more detailed or complicated or cannot be summarized with the options provided in the dropdown menu in Notre Dame's data entry system.

Attribute for general notes notes about this corner.

If data enterer was unsure of one of the aspects in this entry ID they could request that the person that did a double check on the data look over this entry.

Methods and protocols used in the collection of this data package

Description:

The PLS Surveys were conducted from 1804-1849 in Illinois. These records were acquired from Hubtack Document Resources (https://new.hubtack.com/).

The PLS data from the records were transcribed by 43 individuals at Notre Dame from June 2013 to November 2022.

Individuals from Notre Dame who entered the data are: Gabrielle Acampora, Kate Augustine, Kim Bauer, Amanda Buerger, Garret Blad, Caitlin Broderick, Briget Bruns, Will Chronister, Jaclyn Cooney, Margaret Corcoran, Mariel Cuellar, Jill Deines, Matthew Donahue, Isaac Evans, Nicole Fantozzi, Benjamin Foster, Quercus Hamlin, Annie (Ye Na) Han, Alec Helmke, Da Som Kim, Marissa Kivi, Hannah Legatzke, Anna Levesque, Claire Mattison, Kyle McAvoy, Emily Mears, Nicole Micelotta, Emily Miller, Michelle Mueller, Alex Muench, Erin Nguyen, Rebecca O'Neil, Luke Onken, Jody Peters, Annie Pappas,Sam Pecoraro, Kaitlin Powers, Grace Saalman, Ian Shuman, Michael Spoltore, Will Tintor, Zoe Volonec, Christina Wiech.

The notes were originally entered into Notre Dame's online GLO form (http://www3.nd.edu/~paleolab/GLO/) connected to a MySQL database. This online form was disabled in Summer 2017 and data entry was moved to a form connected to a Qualtrics project. After data for each township were entered, the individual who entered the data, double checked for any discrepancies in tree names, diameters, bearing degrees or links distance, and the number of corners expected were entered. A separate individual then did a second check of the data looking again for any discrepancies or unexpected entries that needed double checking. Contact Jody Peters (peters.63@nd.edu) to see protocols for these data checks. Data in the MySQL or Qualtrics database were then exported to a csv, double checked and used to georeference the corners to the x,y coordinates for each corner from a GIS shapefile. For version 1.8 and later (see the version column in the dataset) the georeferencing and quality control checks were done using the Georef_R.R and PLS Summary Code.R code found in this GitHub repository: https://github.com/PalEON-Project/IN_ILTownshipChecker

For versions 1.7 and lower (see the version column in the dataset), the following is the set of quality control checks conducted.These checks were transferred to the Georef_R.R code checks.

The PLS Summary Code.R had additional checks added after it was run on version 1.8-1 so was run again for version 1.8-2 and corrections were made.

Data Processing Steps for version 1.5-1, 1.6, and 1.7

1. Added GIS pointX and pointY using the entryID and UniqueID for the corners.

2. Left in Understory notes. [Note these are no longer being entered in versions 1.8 and above) 3. Added column for the TRP (township, range, primemeridian concatenated)

4. Added column for the version number

5. We had added the waterwet column after the v1.5 data was entered, so went back and checked all No tree/No data in each township grouping to entries to make sure they were labeled correctly and labeled if they were Water or Wet.

6. Removed preceding spaces. Make new column (i.e., verbatim_b, verbatim2_b, etc). Sort by verbatim, then use formula =trim(cell#). Don’t use this formula for the 88888s and 99999s. Just copy those over. Copy full column, then paste special. Then delete old verbatim column and rename verbatim_b as verbatim.

7. Sort by verbatim, then copy verbatim to L1_tree1 column, then sort by verbatim2 (and 3 and 4) then create L1_tree2 (and 3 and 4) by doing an if statement that changes “dittos”s (“, Do, etc) to the tree in the L1_tree1 column for that corner.

8. L3_tree1, tree2, tree3 and tree4: convert Trees 1, 2, 3, and 4 into Level 3 tree names

9. Put No Tree and No Data and Water in the L1_tree1 column (But not in the other 3 tree columns. Put in NAs in for the other 3 columns in step 12).

10. Put in NAs in L1_trees, L3_trees, diameter, degrees, chainstrees for Tree 2, 3, 4 with No Trees and for Tree 1,2,3,4 with No Trees, No Data, and Water.

11. Remove “Null” entries which will mainly be found in ecotype notes through the fixed column 12. Create Pivot Table in new worksheet with Summary of a. TRP counts b. L3 then L1 trees (nested) with counts of L1 trees for all 4 trees (to make sure the L1 trees are in the correct L3 tree categories) (make sure all L1 trees are in the correct L3 category) c. Diameter counts for all 4 trees (make sure there aren’t any weird diameters – check diameters 60 or greater) d. Degrees counts for all 4 trees (make sure no degrees >90 or if so include a note) e. Chainstrees counts for all 4 trees (look for any weird tree distances) f. Check that all the pivot table counts are the same for diameter, degrees, chainstrees g. Get counts of x and y coordinates. Make sure there is the same number of unique coordinates as there are TRPs. Then make sure the counts for the TRPs, x and y coordinates match up.

13. NOTE: There are 2 pairs of corners (4 individual corners) where the tree information is identical in each pair of corners. The notes for these corners were double checked and it was not a data transcription error on our part, this was how the notes were written from the PLS records. We are leaving these corners in the dataset as of now since we assume that one of the corners did have the trees recorded, we just aren't sure which corner it is. However, we removed these entries used for the biomass statistical analyses msb-paleon.26 package as described in the GitHub repository: https://github.com/PalEON-Project/PLS_products.

Here is the list of the 4 corners by listed by TRP and entry_id for corners that have identical tree information:

23N5W3 648480

23N5W3 648496

5N2E4 884

5N2E4 820

In the data labeled 2.1 in the version column there are 7,351 entries from 77 townships that were originally entered by Marlin Bowles at The Morton Arboretum. Bowles used a different data entry system than used by the McLachlan lab at the University of Notre Dame. Three individuals from Notre Dame, Jody Peters, Ian Shuman, and Annie Pappas checked the data from Marlin against the PLS notes and made updates where needed and formatted the data to match the current dataset.

Records that have NA values for all entries in the following columns are from the Marlin database. The columns include: page, sectiona, sectionb, interiorsection, interiordir, refcorner, traveldir, secondpass, and chains.

The 77 townships are:

42N6E3, 42N8E3, 45N12E3, 46N12E3, 45N10E3, 45N11E3, 44N11E3, 44N12E3, 43N10E3, 43N12E3, 43N13E3, 45N9E3, 46N9E3, 46N5E3, 41N6E3, 41N7E3, 41N8E3, 41N9E3, 42N13E3,

Abstract:

PalEON (the PaleoEcological Observatory Network) is an interdisciplinary team of paleoecologists, ecological statisticians, and ecosystem modelers. Our goal is to reconstruct forest composition, fire regime, and climate in forests across the northeastern US and Alaska over the past 2000 years and then use this to drive and validate terrestrial ecosystem models. We will develop a coherent spatiotemporal inference framework to quantify trends and extreme events in paleoecological and paleoclimatic time series. Variables such as forest composition, fire regime, and moisture balance will be inferred from corresponding paleoecological proxies, with rigorous estimates of uncertainty.

These datasets will be applied to improve terrestrial ecosystem models in two contexts. First, we are developing specific data products, such as high- resolution settlement-era forest composition maps from witness tree and General Land Office data, that can be used to drive ecosystem models. PalEON will develop formal data assimilation tools that will allow the models we use to forecast on centennial scales to be informed by decadal- to centennial-scale data. Second, are developing data products for the purpose of model validation (e.g. fire-frequency reconstructions from sedimentary charcoal data). These long-term validation datasets will help us assess the ability of these models to capture past dynamics correctly, and will help us understand why their future projections are so divergent.

Description:

The McLachlan lab at the University of Notre Dame is continually entering PLS data for Illinois. When data have been entered, georeferenced, and quality checked for a group of new townships (typically in the range of ~50-150 townships) or when a new analysis is conducted or data processing step is updated, a new version is created (see the version number in the data table). As new analyses are conducted or as questions come up about specific data entries, those entries will be checked in the notes and updated as needed in the data table with subsequent versions.

The original set of data listed through version 2.0 on the data table was archived in EDI as the msb-paleon.28.0 package. Data for an additional 36 townships were added for the msb-paleon.27.1 package.

The McLachlan lab will continue to enter data and update the msb-paleon.28 package as data are processed. This will take place as time is available to process the data to make these updates.
