Jim Regetz, Matthew B. Jones, Rushiraj Nenuji, Jeanette Clark, Maggie Klope. 2026. vegbankr: An R API package for the VegBank data system. Version 1.0.0. VegBank. doi:10.82902/J1MW28

This package is an R client for VegBank, the vegetation plot database of the Ecological Society of America's Panel on Vegetation Classification, hosted by the National Center for Ecological Analysis and Synthesis (NCEAS). VegBank contains vegetation plot data, community types recognized by the U.S. National Vegetation Classification and others, and all ITIS/USDA plant taxa along with other taxa recorded in plot records. As a VegBank API client, the vegbankr package currently supports querying and downloading vegetation plot records and other supporting information from the VegBank database, and will soon support validating and uploading new data to the VegBank database as well.

VegBank in general, and the vegbankr package in particular, are open source, community projects. We welcome contributions in many forms, including code, data, documentation, bug reports, testing, etc. Use the VegBank discussions to discuss these contributions with us.

Installation

The vegbankr package is not yet available on CRAN, but you can install it directly from this GitHub repository using either the remotes or devtools package. First install one of those packages, and then use it to install vegbankr as follows:

# or use `devtools::` if you prefer
remotes::install_github("nceas/vegbankr")

Usage examples

To view more details about the VegBank API ... you'll have to be a little patient. It's still in development! Keep an eye on the core VegBank repo at https://github.com/NCEAS/vegbank2 for developments and announcements.

On that note, prior to its production release, the main VegBank API (https://api.vegbank.org) may or may not be available at any given time. However, until then, you should be able to explore and prototype against the development API (https://api-dev.vegbank.org). Configure vegbankr to use the development API using the following expression:

library(vegbankr)

# the package default URL is https://api.vegbank.org
vb_set_base_url("https://api-dev.vegbank.org")

How many projects are currently registered in VegBank?

vb_count_projects()

Search for "GAP" related projects, returning them sorted in descending order by observation count.

vb_get_projects(search = "GAP", sort = "-obs_count") |>
  dplyr::select(pj_code, project_name, obs_count)

Get the first 100 plot observations associated with project pj.11044 (Pennsylvania HP Delaware Water Gap), sorted by author_obs_code, then check out where they are located.

obs <- vb_get_plot_observations("pj.11044", sort = "author_obs_code",
  limit = 100)
obs |> dplyr::count(state_province)

Grab a single plot observation record based on its "ob" code.

ob.135454 <- vb_get_plot_observations("ob.135454", detail = "full",
  with_nested = TRUE)

Get the taxon (plant) observations associated with this plot observation, displaying them in order based on the plant code of the current taxon interpretation.

vb_get_taxon_observations("ob.135454") |>
  dplyr::arrange(int_curr_plant_code) |>
  print(n = 35)

Now search for community concepts with the string "_sequoiadendron_".

sequoia_communities <- vb_get_community_concepts(search = "sequoiadendron")

Determine which concept has the most plot observations, then retrieve all of those plot observations from VegBank.

sequoia_plots <- sequoia_communities |>
  dplyr::arrange(-obs_count) |>
  dplyr::slice(1) |>
  dplyr::pull(cc_code) |>
  vb_get_plot_observations()

Authentication

VegBank API write endpoints require a Bearer token. Set it once per session and all subsequent API calls include it automatically.

Step 1 — Obtain your tokens

Visit the VegBank login page and authenticate with your ORCID credentials. You will receive a JSON response containing an access_token and a refresh_token:

{
  "token": {
    "access_token": "eyJhbGciOiJSUzI1NiIsInR5cCI...",
    "refresh_token": "eyJhbGciOiJSUzI1NiIsInR5cCI..."
  }
}

For more details see the API authorization docs.

Step 2 — Set the tokens in R

You can provide individual token strings:

vb_set_token(
  access_token  = "eyJhbGciOiJSUzI1NiIsInR5cCI...",
  refresh_token = "eyJhbGciOiJSUzI1NiIsInR5cCI..."
)

Or pass the full JSON response or a named list directly:

# Named list
vb_set_token(tokens = list(
  access_token  = "eyJ...",
  refresh_token = "eyJ..."
))

# JSON string (e.g. copied from /authorize response)
vb_set_token(tokens = '{"access_token": "eyJ...", "refresh_token": "eyJ..."}')

Step 3 — Upload data

# dry_run = TRUE validates the payload without committing to the database
vb_upload_plant_concepts(plant_concepts =
  data.frame(
    user_pc_code = "PC_1",
    name = "Test concept",
    vb_rf_code = "rf.33",
    vb_status_py_code = "py.511",
    plant_concept_status = "test status",
    start_date = "2026-03-01"
  ), dry_run = TRUE)

Token lifecycle

Automatic refresh. When an API request is made and the access token has expired, vegbankr will automatically use the stored refresh token to obtain a new token pair — no manual intervention required. If the refresh token has also expired, you will be prompted to re-authenticate.

Check validity. You can inspect token status at any time:

vb_access_token_is_valid()
vb_refresh_token_is_valid()

Manual refresh. To explicitly refresh the tokens before they expire:

vb_refresh_tokens()

Clear tokens. To remove all stored tokens from the session:

vb_unset_token()

A 401 Unauthorized response means the token is missing or expired — repeat Steps 1–2 to re-authenticate.
