Call-for-Data Species Observations

The 4-County CWMA “Call-for-Data” project is a region-wide monitoring effort to gather more information on suspect weeds, as well as monitor for occurrence or spread and inform risk assessments for these species.

Our “Call-for-Data” species list includes “newly establishing or expanding invasive or naturalized weed species within the 4-County CWMA region.” These species are non-native, uncommon, and have a high likelihood of being invasive in the CWMA region (i.e., known to be invasive nearby or in similar climates). Some of our Call-for-Data species may have already been nominated for ODA or WSDA noxious weed status, are on a monitor list, or are under consideration for nomination. Information collected here may be used to justify future inclusion on a state noxious weed list.

The purposes of this project is to:

  1. Provide information on distribution, abundance, or biology for a species that may or may not be common but is likely under-reported.
  2. Increase the chance of finding the first record (or verify existence and identification) of a species of great concern that is not yet known from the area, 
  3. Encourage reporting by fostering a regional data sharing network.
  4. Provide information to support a species-specific control effort.

Data collection is carried out through partnerships between 4-County CWMA partners and stakeholders as well as by community/citizen scientists. Please scroll down for our various reporting options!

2020 Call-for-Data Species List :

We encourage and accept data on all invasive and naturalizing species. However, to ensure a coordinated monitoring effort, we highlight approximately 4-5 species each year. Please share our 2020 Call-for-Data outreach flyer!

Current distributions for these species are shown in the below 2020 Call-for-Data Species Distribution Map (courtesy of Lindsey Wise).


Data reporting methods:

We encourage participants to adopt our 4-County CWMA invasive plant observation data standards for your contributions. You can submit your weed observations on a number of different online and mobile platforms, as described below.

Data sharing apps

  • iMapInvasives Oregon
  • iNaturalist
  • EDDMapS
    • Within Washington State, please send reports to EDDMapS. They also have a mobile app!
    • This platform accepts individual observations and bulk uploads.
  • Oregon Invasive Species Hotline
  • WeedMapper
    • If you’d like to learn more about ODA’s WeedMapper, check out this handy quick start guide.
    • WeedMapper reports automatically get integrated into the iMapInvasives Oregon dataset.

Please also consider reviewing Oregon Department of Agriculture’s current watch list and submitting supporting information about infestations to inform formal noxious weed risk assessments. Also, consider nominating species for noxious weed status.

For new county records of these species, please consider vouchering populations to support taxonomic, mapping, and floristic analysis based on voucher data rather than observation data. We recommend submitting vouchers to each of the following herbariums: Portland State University Herbarium (HPSU), Oregon State University Herbarium (OSC), and the University of Washington Herbarium (WTU). Vouchering instructions for each institution are available (HPSU, OSC, WTU).

    • Balfour’s balsam (Impatiens balfourii)
    • ventenata grass (Ventenata dubia)
      • Removed from 2018 list, in consideration of this species’ reputation as a well-established invasive and its status as a Washington state-listed noxious weed. However, its distribution in the 4-County CWMA region is still poorly documented.
  • 2016 Call-for-Data Species list
    • drooping sedge (Carex pendula)
    • greater celandine (Chelidonium majus)
    • wild basil (Clinopodium vulgare)
    • Balfour’s balsam (Impatiens balfourii)
    • Impatiens bicolor
      • Removed from 2017 list, in consideration of this species’ very limited local distribution. Also, the focus for this project has shifted away from documenting extremely rare weeds.
    • ventenata grass (Ventenata dubia)
    • Evergreen bugloss (Pentaglottis sempervirens)
      • Removed from 2017 list, due to adequate levels of documentation achieved. Species should still be considered for future risk assessments, based on trends seen in the collected data.
