US SWAP National List IUCN Red List Canada Species at Risk Mexico California Leaf-nosed Bat The California leaf-nosed bat has gray to dark brown pelage, with often-paler ventral fur. The California leaf-nosed bat prefers hunting sans echolocation, using its sizeable ears and eyes to detect its prey outright. This bat mostly eats large insects and is one of the few bat species to eat caterpillars; it may supplement its insect diet with cacti fruit. This desert species can be found in scrub habitat of the Mojave and Sonoran Deserts. It is not well-suited to long flight and does not migrate nor hibernate. Mothers rear one pup per year. The California leaf-nosed bat roosts in rocky areas, caves, and mines and can survive to 20-30 years of age in the wild.

Back to Search ERROR WARNING: Audio Recording Time not within Start and End Times HOW TO RESOLVE: A survey window conflict occurs when a record's timestamp ('Audio Recording Time') falls outside the reported 'Survey Start Time' and 'Survey End Time'. For acoustic datasets, address errors based on the number of records affected. A few error rows can be removed or resolved through manual adjustments to the Audio Recording Time. If many records are affected, check for consistent time offsets or other systematic shifts, then resolve by batch-shifting times for uniform offsets, removing pre/post-survey recordings that fall outside the actual survey period, or extending the survey window to include legitimately captured records. ADDED EXPLANATION: To troubleshoot survey window conflicts, first check if timestamps align with known survey date(s) and times. If they do, detector misconfiguration is unlikely. If they differ, look for uniform shifts (e.g., in minutes, hours, or dates) that may have been caused by incorrect detector presets; these can be corrected by adjusting values in a spreadsheet or coding tool. Many applications let you add or subtract date/time values arithmetically. Note that detector datetime formats that include a "T" between date and time, or that include a time zone at the end (e.g., "-07.00") can make it difficult to arithmetically adjust timestamps in programs like Excel. If so, If so, use {Find/Replace} tools to swap the “T” for a space, and replace the time zone portion (e.g., “-07:00”) with a blank value, then re-format the column as a standard date/time. Records captured between detector recording-ON and survey start, or survey end and detector recording-OFF should be removed. Errored records resulting from inaccurate survey start/end times can be resolved by extending the listed survey start/end times to accommodate documented recording times.

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.
