Phenophase Photo Guidelines
Help us illustrate phenology through images!
The USA-NPN National Coordinating Office invites you to publicly share your high quality/high resolution photos of plant and animal phenophases for education purposes via our Phenophase Photo Flickr page. You can help us build a database of photos for the 1100+ species and their phenophases, as listed in Nature’s Notebook.
These photos of plant and animal phenophases will be used in educational and training materials for our volunteer observers. If you are interested in submitting digital images of species' phenophases, please review the guidelines and directions below.
Thank you for your interest in the USA-NPN and your willingness to share your work with us!

The purpose for collecting these photos is for observers to clearly see the distinguishing characteristics of a given phenophase for a given species. Therefore accuracy in both species and phenophase is important. We ask that you please carefully review each photo you submit for accuracy of the phenophase. Because we are limited in staff time and cannot review every photo for accuracy, we must rely on you, the contributor, to properly identify the species for the photos you submit, especially since these photos may be used by others in teaching and outreach settings.
Photo Guidelines Before you Submit
Before you contact us to let us know you have photos to share, please take a minute to:
- Verify the genus and species of your plant
- Check to be sure the plant is currently available for observation on our Plant and Animal List
- Identify which Functional Group the plant is in by looking at the datasheet accessible from the species profile page. The Functional Group can be found on the upper left side of the page, as in the example below for the white oak, "Trees and Shrubs Deciduous (with pollen)".
Once you have done that, you may proceed to the steps below.
Digital image resolution is measured in pixels, the single squares you see when you zoom in on an image. Higher resolution images provide more flexibility in terms of how photos can be cropped and displayed on websites and in print to clearly illustrate the phenophases. With this in mind, our desired resolution range is 500x400 to 3000x2000 pixels, or a resolution of 300 pixels per inch (ppi) or dots per inch (dpi). If you do not have a macro lens or cannot zoom into the tiny plant parts, please submit photos at the high end of this range so that we can enlarge and crop the image.
We ask that for each photo you submit, its filename follow our standard file naming convention of “Genus_species_PreferredPhotoCredit_PhenophasePictured” (for example “Syringa_vulgaris_JosephPLilac_OpenFlowers” or “Cornus_florida_USGeologicalSurvey_Leaves”). Please find the scientific name (Genus species) of the subject of your photo in the title of its Nature’s Notebook species profile page (search the species list). Use the exact name of the phenophase from the phenophase definitions found on the species profile pages in Nature's Notebook in the title of the photo for consistency. If you plan to contribute more than one photo for a species, also add a unique identifier at the end of each filename (for example, Genus_species_JosephPLilac_OpenFlowers_01, Genus_species_JosephPLilac_OpenFlowers_02, etc.).
We are very grateful to you for sharing photos that will support our effort to visually inform our volunteer observers, and we will happily credit your work. Be prepared to specify how you would like the photo credit to read when you submit the photo (for example, "Joseph P. Lilac", "J.P. Lilac" or "U.S. Geological Survey"). If you do not wish to add a credit for your photo, please tell us it should be credited as “Anonymous”.
Please let us know if there are any copyrights or licenses attached to your photo. If you need information regarding copyrights and licensing, please visit Creative Commons.
USA-NPN can only accept photos with copyrights or licenses that allow end users to crop and resize as needed to clearly illustrate the phenophase definitions. We can accept photos with a Creative Commons Attribution license, Attribution-NonCommercial-Share Alike license, Attribution-ShareAlike license, Attribution-NonCommercial license, a Public Domain status, or an equivalent copyright or license.
We need photos of our Nature's Notebook species that are focused on a single phenophase or a photo series showing the development of a species through a phenophase. Try taking a photo of the same plant, from the same spot, a few times of year during different seasons or taking close up photos of your plant expressing different phenophases. The following examples are the type of photos we are hoping you will contribute!
Each photo shown here was submitted at 1280x960 pixels, 180 dpi, which allowed the NPN staff to process and edit the photo to focus in on the details of a phenophase. Sharp focus and good contrast help to make the details easily readable - and your photo useable. It is the details in your photos that will help inform our participants of the cues they need to be looking for while making observations on their species.
Photos of People
Please do not submit photos of people from trainings, making observations in the field, or with school groups, etc. to the USANPN Phenophase Photo page. If there is enough interest, we may consider a second Flickr account for events and people.
You are welcome, and encouraged, to share photos of your events at any time, with proper permission, on any of our social media pages: Facebook, Pinterest, Instagram, and twitter using hashtag #NaturesNotebook.
In order to share photos of people making observations, have each subject sign a media release for your organization. This is especially important when working with minors.
We have chosen to use a Flickr account for ease of use and accessibility. To contribute a series of phenophase photos to our USA-NPN Phenophases Flickr account, we ask that you FIRST send an email to our staff at email@example.com to let us know how many photos you have to contribute.
Once the USA-NPN Staff receives your email, you will receive in return, instructions on how to proceed.
Depending upon how many photos you have to share, you will then either be given a unique email address to send them to, which will post them directly to the Flickr account, OR you will be be asked to share them via Dropbox file (if you have more than 10 photos to share). You do not need to create a Flickr account to participate.
Again, please be sure to follow the guidelines for naming, crediting, and licensing described above when submitting photos. You should be prepared to follow the naming convention, apply the desired licence, and include information about the photographer so it can be credited properly when it is uploaded to the Flickr site. Otherwise we will be unable to share your photos.
If you wish to use photos that appear on the USA-NPN Phenophase Photo Flickr page, please be sure to include the photographer credit and licensing information included with the photo. You do not need to have a Yahoo! account to download the photos at full resolution. Note that when the photo downloads you may not receive the standardized name with credit when it is saved to your computer. Be sure to check that information and save it with your photo on your computer for use in print and online.
Photos used on a website or in print should be captioned with the photo credit. If this is not practical, the credit should be added to a photo acknowledgement page. Collaborators are welcome to use the photos contained within the Flickr page for educational purposes, with the credit attached and any licensing information with it.
Group leaders may consider creating a suite of phenophase photos for species being observing locally, as demonstrated here.
If you have questions, please contact us at firstname.lastname@example.org.
Thanks for your interest in phenology and photography!
