US SWAP National List IUCN Red List Canada Species at Risk Mexico Eastern Red Bat The eastern red bat has light gray-brown fur on the upper side of its body and more whitish fur on the under side, with an orange-red face. Females are more likely to exhibit paler coloring. This species prefers to live within more remote, forested areas. Males are more likely to occur in cooler regions, with females tending to occur in warmer, lowland areas. This bat will roost amongst the foliage of deciduous or occasionally evergreen trees. In winter, this species hibernates by burrowing into leaf litter and bunch grass. Their diet consists primarily of moths but other insects such as beetles and members of Hemiptera are also featured on the menu. Females commonly have more than a single pup (baby bat), twins or triplets, but can have liters of up to five pups.

Back to Search ERROR WARNING: Auto Id or Manual Id required for recording. HOW TO RESOLVE: Enter missing required data based on the template's header rows—the third row indicates required status by field, and the second row lists data type restrictions. Ensure each record includes values for all required fields before re-uploading. In this error instance, the 'Auto Id' or 'Manual Id' field is missing for a given recording. Example: The "Auto Id" field in the stationary acoustic template only allows entry of a controlled category listed in second header row. ADDED EXPLANATION: Surveys must include key fields that answer the "where, what, when, and who" questions: either a GRTS Cell ID or latitude/longitude to locate the survey, a Site Name to describe the place, survey start and end times, and the names of surveyors. Each survey type may also require a few additional fields. If required columns are missing entirely, the upload wizard will block the file. If required columns are present but individual rows lack values, those rows will be flagged while the rest of the file can load. Use the template's informational header rows to identify which fields are required and ensure each data entry row contains values for these fields before uploading.

Back to Search ERROR WARNING: is an invalid float HOW TO RESOLVE: Use the template's second header row to view data type requirements and replace erroneous data in flagged field based on the field's listed requirements. Non-numeric entries are typically the source of this error. Example: The "Latitude" field in the stationary acoustic template accepts float data. Non-numeric entries, e.g. a string value, or numbers with incorrect characters like a comma. If the "|" pipe symbol at the start of header row gets accidentally removed, those rows will no longer be treated as headers and instead will be read in as data rows. This results in categorical or data type errors like, " is an invalid float". Simply make sure a pipe symbol "|" is included at the start of each header row and re-upload your csv to the Partner Portal. ADDED EXPLANATION: Each field in the template requires a particular data type (text, integer, decimal, date-time, or true/false) or a controlled categorical response. Values that don't match these requirements will be rejected. In a spreadsheet, adjust cell formats or use find/replace to convert values—for example, changing numbers stored as text into actual numbers, converting decimals to integers, or trimming time-zone suffixes from date-time strings. For widespread issues in non-required fields, consider omitting the column entirely and re-uploading.

Back to Search ERROR WARNING: An entry of this recording name already exists and is part of another survey event HOW TO RESOLVE: Duplicate errors occur when the system encounters repeated survey records. This error typically occurs when duplicate records occur across multiple uploads. Locate the conflicting file in the Partner Portal's Surveys tab, download it from Project Files, and compare contents with your current file. Keep the most complete version and remove overlapping rows from the other, then re-upload. If duplicates persist despite removing and re-uploading affected data, contact the NABat Technical Outreach Team. ADDED EXPLANATION: Duplicate detection logic varies by survey type. For emergence count surveys, each unique combination of Site Name, Exit Identifier (if provided), Surveyor, and Species should appear in a single row—multiple rows from the same surveyor for the same combination are flagged as duplicates, whereas rows from different surveyors are averaged to produce the final count. Roost count surveys use different logic: counts are summed within each surveyor's report for a given site, section, and species, and if multiple surveyors report, their sums are averaged—so duplicates are not flagged in the same way. Beyond survey-type logic, duplicate errors can arise from re-uploading the same data in quick succession, inadvertently uploading the same survey under different file names, accidental copy/paste duplication within a file, or leftover data from older versions of the upload logic. When identifying duplicates within a file, Excel's Conditional Formatting (Home → Styles → Conditional Formatting → Highlight Cells → Duplicate Values) can highlight repeated values in a unique identifier column. For surveys lacking a single unique field, create a new column that concatenates key fields to form a composite identifier. When comparing across uploads, note the conflicting file's name and created date in the Partner Portal, download it, and review side-by-side with your current file to determine which version is more complete or accurate. In rare cases, the database may retain artifacts of previously deleted data that trigger duplicate errors on subsequent uploads—if you suspect this scenario after repeated removal and re-upload attempts, contact the NABat technical outreach team to investigate.

Create Account Plan Project Collect Data Prep/Process Data Upload Data Data QA/QC Get Data Species Codes Resource Library PLAN YOUR NABAT PROJECT Jump to... Create a new NABat project Select GRTS Cells for monitoring Field Apps for Data Collection Saving transects for mobile surveys Saving survey sites on the map Create a New NABat Project Registered users can create new projects from the My Projects tab of the NABat Partner Portal . Users are free (but not required) to divide data into separate projects spatially or by survey type, but data should never be separated into distinct projects temporally (e.g., USGS NABat 2016, USGS NABat 2017, etc.). The following provides step-by-step guidance on creating a new NABat project. 1. Log into the NABat Partner Portal . First-time users will need to create an account . 2. Once logged in, navigate to the My NABat tab from the top menu bar. 3. Click the + New Project button located at the top right of the page. 4. Follow the prompts in the Project Wizard to enter the required information to create your new project. You will be prompted to enter Project Info > Project Members & Data > Project Summary information. Carefully read the NABat Data Use and Sharing Agreement when establishing your project's data sharing elections. 5. To finalize your new project, select the Create Project button. Project details can be edited at any time by clicking the green Edit Project button in the upper-right corner of your project's Details tab. Note: If your owning organization does not appear in the drop-down menu, please fill out the New Organization Form , and a member of the Technical Outreach team will add it to the NABat Partner Portal . Please allow up to 24 hours for the request to be processed. Select GRTS Cells for Monitoring The NABat Cell Selection Tool allows users to filter, select, order (based on GRTS priority ranking), and claim cells for monitoring while also indicating to other NABat partners where monitoring efforts are already occurring. This workflow ensures monitoring efforts follow the NABat sample design and reduces redundancy in monitoring efforts. 1. Log in to the NABat Partner Portal . First-time users will need to create an account . 2. Navigate to the My NABat tab from the main menu bar and select your project of interest project. 3. Click the Cell Selection Tool button on the right of your project's Details page; a new page will load with a map. The Cell Selection Tool features a complete map of all NABat GRTS cells in the project’s sample frame, along with an evaluation table that compiles GRTS cells based on user-applied filters. 4. Use the search bar above the map to apply spatial filters and select the area of interest. Users can add geographic or jurisdictional filters (e.g., state, county, land management agency, etc.) or locate cells based on GRTS ID, geographic coordinates, or NABat sampling priority. Users can also make custom selections using the drawing tool by clicking the Draw custom spatial filter button (polygon symbol) above the map. Cells within the selected area will appear with a light blue border. Users must the APPLY FILTER button (top-right corner of map) to activate the filter. Note: Spatial filters can be combined with AND/OR logic by clicking the gear icon (top-left corner of map). Users can also select/deselect cells with a double-click and select from a variety of map layers by hovering over the button in the top right corner of the map. 5. After filtering to the desired area, move to the Evaluation Table to the right of the map and tick boxes under the Select Survey Types header to indicate the type(s) of monitoring planned. Users can make multiple selections. Ticking boxes will update the table with the cells’ current selection status for the chosen monitoring types. Note: Cells that have already been selected for survey by another project are labeled as such. Links to details and contact information for the owning project will be provided. 6. Once cells are added to the table, they can be evaluated and selected for survey. Use the arrows in the GRTS Cell ID column header to cells by priority ranking (lower GRTS number = higher priority). Users should claim cells for survey beginning with the highest priority cell (i.e. lowest GRTS Cell ID) and working down the list, claiming as many cells for survey as resources will allow and only skipping cells based on factors like accessibility, project resources, etc. It is more important to monitor cells in priority order than to monitor many cells. If cells must be skipped, select an explanation from the drop down menu (e.g., Not safe, Logistical constraints, etc.). Note: Make use of the Bulk Change button to edit many cells simultaneously. 7. When cell evaluation is complete and final selections have been made, click the Save button (above the table) to apply cell selection changes to the project. All cells selected for survey will now appear on the project homepage (below the project map) with a green circle. 8. Return to the Cell Selection Tool at the conclusion of each field season/prior to the start of a new field season to reevaluate selections and ensure resources and circumstances allow the same level of effort as the prior season. If previously monitored cells will not be monitored in the upcoming season, those cells should be released so it is clear to other NABat users that they are now available for monitoring. If resources allow for additional monitoring in the upcoming season, users should follow GRTS priority order and claim as many additional cells as resources permit. Saving and Exporting Sites for Survey Survey locations can be saved in the NABat Partner Portal and exported for use in a handheld GPS unit. To create and export points: 1. Log in to the NABat Partner Portal. First-time users will need to create an account. 2. Navigate to the My Projects tab from the main menu bar and select a project. Scroll down to the project map. 3. NABat protocols for stationary acoustic surveys call for ≤ 1 detector per grid cell quadrant. Hover over the Map Layers button in the top right corner of the map and select the NABat GRTS Cells and CONUS 5km Grid Cells layers to visualize grid cells and their quadrants. Note: The Imagery layer may also be turned on to help identify potential detector locations. 4. Once a prospective site has been identified, select the Mark a survey location button (upper-left corner of map) and click the map to create a survey location. A dialogue box will appear on the map with details about the survey point, including latitude and longitude. 5. Click the Edit button in the bottom right corner of the dialogue box. Provide a name for the new survey location and use the Survey Type drop-down menu to indicate the type of survey point (i.e., “Stationary Detector”). Users may also enter a site description or adjust latitude and longitude values. Note: To use this point when uploading metadata, the Site Name provided in the bulk upload template must be an exact match to the Name of the point. 6. Click the Save button in the bottom of the dialogue box to update site details. 7. To export location information for saved points, click the Download KML | GeoJSON button, located in the top right of the map (immediately right of the Upload KML | GeoJSON button). 8. Once location data have been downloaded, they can be imported into a handheld GPS unit and used in the field.
