The Washington Natural Heritage Program (WNHP) feels it is important for land use planners to consider information on rare species and biologically sensitive areas when developing land use plans. Therefore, our agency provides means by which the public can access the information we maintain on rare plant species and high quality ecosystems.
The Information Request Self-Service System makes this process easier by allowing you to access a list of the townships, ranges, and sections (TRS) where Natural Heritage features are reported to occur. Step-by-step instructions for using our Self-Service System are provided below. Please read through all of the steps and then proceed to the ‘Links’ section to start your search. You might want to save this page in your favorites for quick access in the future.
NOTE: Do not print a copy of the TRS list for future use. Information on rare plants and high quality ecosystems is updated frequently. If you use a printed copy of the TRS list, you are not referring to current data.
Consult the TRS List (opens a pdf in a new window)
- For a description of the Township, Range, and Section system of land survey, click here.
- Scroll through the list to find the TRS for your project area. The list is arranged in alphanumeric order.
- You may also use the ‘Search’ tool (binoculars) to find your TRS. When using the ‘Search’ tool, make sure you use the correct format.
T_ _N R_ _E/W S_ _
* Must use two digit numbers; add a zero to the front of single digit numbers.
* Single space between township, range, and section.
- If you cannot find the TRS for your project area, continue on to step 2.
- If you have found the TRS for your project area, continue on to step 3.
TRS for your project area CANNOT be found in the TRS table
If you cannot find the TRS for your project area by scrolling through the list or by using the ‘Search’ tool, the Washington Natural Heritage Program does not have current information on rare plants or high quality ecosystems for that TRS. Please note: this does not mean that Natural Heritage features do not occur in this area. It simply means that if a Natural Heritage feature exists in this area, our agency has not received a report of its occurrence.
TRS for your project area HAS been found in the TRS table
If the TRS for your project area has been found in the TRS table, you must complete an Information Order Form. It is a ‘fill-in’ form that allows you to enter information while the form is displayed on your computer screen. You may then print the form for mailing or faxing, or you can save the form and attach it to an email.
