Monitoring Progress

Three restoration sites along the Lewis and Clark River are the focus for herbaceous plant species monitoring in accordance with the standardized “Protocols for Monitoring Habitat Restoration Projects in the Lower Columbia River and Estuary” (Roegner et al. 2009). These sites have been monitored for changes in plant community composition beginning in 2006 and continuing into the foreseeable future (as of 2022).

By systematically collecting measurements of herbaceous plant species, we can interpret how wetlands are adapting to changes made through adaptive management techniques and inform future decision making.

 

Chronolog Photo Stations

How can you help the park track change over time in these restoration areas? It only takes a smartphone!

There are two Chronolog stations in the park; on the Lower Slough Trail and the Netul Trail both facing towards the Colewort Creek Restoration Site. Visitors place their cellphones upright in the bracket at the station, snap a photo and then email the photo following the instructions on the sign. Once submitted, they receive a reply with a time lapse of the site made up of with other visitor photos. By submitting photos at these Chronolog sites, community scientists can assist park managers track landscape changes over time.
