Plant Community Composition And Structure Monitoring For Agate Fossil Beds National Monument, 2014 Annual Report, Michael Prowatzke, Stephen K. Wilson Mar 2015

Plant Community Composition And Structure Monitoring For Agate Fossil Beds National Monument, 2014 Annual Report, Michael Prowatzke, Stephen K. Wilson

United States National Park Service: Publications

Abstract

This report presents the results of vegetation monitoring efforts in 2014 at Agate Fossil Beds National Monument (AGFO) by the Northern Great Plains Inventory and Monitoring Network (NGPN).

During the fourth full year of field work, crew members from NGPN visited six plant community monitoring plots to collect data on the vegetation at AGFO. This is part of a long-term monitoring effort that will sample six of 15 randomly located upland plots every year, so that each plot is visited for two consecutive years and then rested for three years, on a five-year rotating basis. NGPN staff captured data …

Restoration Of Bison (Bison Bison) To Agate Fossil Beds National Monument, A Feasibility Study, Daniel S. Licht Nov 2014

Restoration Of Bison (Bison Bison) To Agate Fossil Beds National Monument, A Feasibility Study, Daniel S. Licht

United States National Park Service: Publications

Executive Summary

Agate Fossil Beds National Monument is a 3,057-acre park located in western Nebraska. The unit is comprised of northern mixed-grass prairie vegetation, typical of the Northern Great Plains. Weather, fire, and grazing are generally considered to be the ecological drivers of prairie ecosystems and critical for prairie health. However, grazing has essentially been absent since the 1960s. In 2014, a Department of the Interior report explicitly listed the park as a high priority for bison restoration. This report evaluates the feasibility, management options, benefits, and challenges of restoring bison to Agate Fossil Beds National Monument.

A potential bison …


Reply To ‘Co2 Emissions From Crop Residue-Derived Biofuels’, Adam Liska, Haishun Yang, Matthew P. Pelton, Andrew E. Suyker Oct 2014

Reply To ‘Co2 Emissions From Crop Residue-Derived Biofuels’, Adam Liska, Haishun Yang, Matthew P. Pelton, Andrew E. Suyker

Adam Liska Papers

The soil organic carbon (SOC) model that we used was parameterized with data from arable land under normal farming conditions in North America, Europe, Africa and Asia, but the equation is insensitive to changes in tillage, soil texture and moisture. The model has reasonable accuracy, however, in predicting changes in SOC, residue remaining and CO2 emissions from initial SOC, carbon inputs from residue, and daily temperature; the shoot-to-root ratio used in the geospatial simulation was 0.29 (that is, root carbon is 29% of total aboveground carbon), which did not underestimate carbon input to soil (Supplementary Figure 2 in Ref. …
