Current Vegetation Survey (part of national vegetation mapping program)

Long term vegetation sampling for monitoring and current conditions. Permanent one hectare plots are installed every 1.7 miles in a grid pattern, to be remeasured in an 8-10 year cycle. Above ground vegetation is tallied, numbered, and referenced, where available; shrubs, herbs, forbs species and crown cover are estimated on five 1/20th acre subplots. Down woody debris is tallied using five 51.1’ line transects. Objective is condition database and remeasurability. Locations will also be used to tally lichens, wildlife, etc. on other studies.

Forested plant association classification

This work, which includes sample sites on the Mount St. Helens National Volcanic Monument, extends across forested areas of the entire Gifford Pinchot National Forest.

Riparian/wetland classification for wetlands

The wetland sampling within the Mount St. Helens National Volcanic Monument is part of a larger study on the Gifford Pinchot National Forest. Information gathered will be used to classify riparian/wetland sites into identifiable ecological units that can be used to understand their environmental characteristics and prescribe appropriate management schemes. Study areas in the Monument are Coldwater Lake, Toutle River debris avalanche, and Goat Marsh Research Natural Area. Sample plots were selected to represent different community types (based on species composition and vegetation structure). Wetlands at Coldwater Lake and Toutle River debris avalanche were created as a result of the May 1980 eruption of Mount St. Helens, and thus can provide unique insight into the development of wetlands and plant succession.

Riparian/wetland classification for streamsides

The riparian sampling in the Mount St. Helens vicinity is part of a larger study that extends across the Gifford Pinchot National Forest. Streams sampled on the Mount St. Helens Ranger District are Kalama River, East Fork Fossil Creek, and Pin Creek. The purpose of gathering streamside plot data in this project is to produce a classification of streamside vegetative/geomorphic features. The sampling design is such that plant communities are juxtaposed on their geomorphic surfaces and then related to the stream channel itself. Because this project is being carried out in coordination with a separate Forest Riparian Inventory, we will later be able to relate our riparian information to the aquatic data being  collected by the fisheries/hydrology programs.
