Terrain and Vegetation of Imnavait Creek, AK: Toposequence Study

Entry ID: ARCSS111

[ Update this Record ]

Summary

Abstract: This data report is a summary of environmental, soil, and vegetation information collected from 23 study plots at the Department of Energy R4D research site, located near Imnavait Creek in northern Alaska. Data include site factors, soil classification, description, and physical and chemical properties, and plant species cover. Study plots characterize two typical hillslopes of the Imnavait Creek Watershed. An assessment for photointerpreting vegetation signatures based on data findings is provided. Data are distributed in PDF file format.

Description: Data from this study were classified using Braun-Blanquet sorted table analysis, and were incorporated in creating a map using integrated geobotanical mapping procedures in a Geographic Information System (GIS). The vegetation classification is presented in a final sorted table, and major terrain units, vegetation, and surface forms are described. Also included is a summary of comparable vegetation types from other relevant studies and an areal analysis of the geobotanical maps of the study area. The study area is the Department of Energy R4D research site and is located near Imnavait Creek, AK
