About the datasets:
These datasets include species lists, distribution maps, label data, and access to high-resolution specimen images for vascular plants, bryophytes, algae, lichens, and fungi for the Pacific Northwest region.
The datasets are pre-compiled as HTML files from the PNW Herbaria specimen database. This allows the datasets to be installed locally to a device (mobile phone, tablet, or desktop computer). Our goal is to allow access to the specimen data in remote locations where a network connection is not available. Although the datasets can be viewed on desktop computers they are designed for mobile phones and tablets.
We use these datasets when collecting to target new county records and notable distribution records.

Please respect the Data usage restrictions when using these datasets.
The HTML files can be installed on an Android phone or tablet, iPhone or iPad, or a desktop computer for offline viewing. Instructions for installing to phones or tablets are given below. These should work for most devices; however, due to extensive variation among phones, the instructions given here may require some modification for your particular device.
Data usage restrictions:
Dataset files © 2020 Consortium of Pacific Northwest Herbaria (managed by the University of Washington Herbarium). Ownership of the specimen data contained within is retained by the individual data providers.
These datasets are intended for personal use. They may not be redistributed, sold, or posted for download or display by any third-party entity without prior written permission from the University of Washington.
Precautions regarding the data:
Please use the data at your own discretion. You will notice problems and inconsistencies with both nomenclature and distributions. Although we go to considerable effort to clean and standardize the data, we cannot detect or fix every problem. The quality of the specimen data provided to us varies by taxonomic group. Vascular plant specimens are generally the best curated, followed by bryophytes and lichens.
- The Consortium maintains a checklist for vascular plants which is used to standardize family and scientific names. We also have checklists for bryophytes, algae, lichens, and fungi; however, the nomenclature and family classifications for these groups may not be up to date or complete.
- We intend to exclude records of cultivated specimens. However, not all cultivated specimens are marked as such.
- Some specimens are mapped incorrectly because of faulty latitude/longitude coordinates (usually obtained by using automated georefencing software). We try to detect and hide as many of these as possible, but cannot catch all.
- Precise localities and coordinates are suppressed for species of conservation concern in the public versions of the datasets. These are displayed on the map using large open squares. The squares are aligned to a fixed grid such that the actual location may fall anywhere within the square.
