Executive Summary

The National Park Service (NPS) Natural Resource Condition Assessment (NRCA) Program administered by the NPS Water Resources Division evaluates current conditions for important natural resources and resource indicators using primarily existing information and data. NRCAs also report on trends in resource condition when possible, identify critical data gaps, and characterize a general level of confidence for study findings. This NRCA complements historic resource assessments, is multi-disciplinary in scope, employs a hierarchical indicator framework, identifies and develops reference conditions/values for comparison against current conditions, and emphasizes spatial evaluation of conditions and GIS (map) products.

Congress established the Homestead National …


Plant Community Composition And Structure Monitoring At Agate Fossil Beds National Monument, 2019 Data Report, Molly B. Davis Dec 2019

Plant Community Composition And Structure Monitoring At Agate Fossil Beds National Monument, 2019 Data Report, Molly B. Davis

United States National Park Service: Publications

Abstract

This report presents the results of vegetation monitoring efforts in 2019 at Agate Fossil Beds National Monument (AGFO) by the Northern Great Plains Inventory and Monitoring Network (NGPN) and the Northern Great Plains Fire Ecology Program (NGPFire). This was the ninth year of combined monitoring efforts.

In 2019, crew members from NGPN visited 6 long-term plant community monitoring (PCM) plots to collect data on the upland mixed-grass prairie plant communities at AGFO. This work is part of a long-term monitoring program established to better understand the condition of the vegetation community and how it changes over time. NGPN staff …

Executive Summary

The vegetation inventory project at Niobrara National Scenic River (NIOB) classified and mapped vegetation within the park administrative boundary and estimated thematic map accuracy quantitatively. The project was conducted over a four year period from the summer of 2015 to the winter of 2019. Located in north-central Nebraska, approximately 76 miles of the park is designated as a wild and scenic river. The vast majority of land within the NIOB administrative boundary is private or state-owned.

The project follows guidance provided by the National Park Service (NPS) Vegetation Mapping Inventory (VMI) Program. The overall process includes initial planning …


Vegetation Monitoring At Homestead National Monument Of America, Nebraska, 1998–2017, Sherry A. Leis Aug 2019

Vegetation Monitoring At Homestead National Monument Of America, Nebraska, 1998–2017, Sherry A. Leis

United States National Park Service: Publications

Executive Summary

The Heartland Inventory and Monitoring Network has sampled permanent monitoring sites in three vegetation community types (restored prairie, successional forest, and bur oak forest) at Homestead National Monument of America since 1998 (includes nine sample years). Network scientists record each species, aerial cover estimates of ground flora, diameter at breast height of midstory and overstory trees, and tree regeneration frequency (tree seedlings and saplings) within these permanent sites.

The park has experienced similar periods of drought and wetness through the monitoring record. Ground cover estimates indicate that prairie litter and bare ground are negatively related; prescribed fire cycles …


Plant Community Composition And Structure Monitoring At Scotts Bluff National Monument, 2018 Data Report, Isabel W. Ashton Mar 2019

Plant Community Composition And Structure Monitoring At Scotts Bluff National Monument, 2018 Data Report, Isabel W. Ashton

United States National Park Service: Publications

Abstract

This report presents the results of vegetation monitoring efforts in 2018 at Scotts Bluff National Monument (SCBL) by the Northern Great Plains Inventory and Monitoring Network (NGPN) and Fire Ecology Program (NGPFire). This was the eighth year of combined monitoring efforts.

Crew members from NGPN visited eight long-term monitoring plots to collect data on the plant communities at SCBL. This work is part of a long-term monitoring effort designed to provide a better understanding of the condition of the vegetation community and how it changes over time. NGPN staff measured species richness, herb-layer height, native and non-native species abundance, …


Plant Community Composition And Structure Monitoring At Agate Fossil Beds National Monument, 2018 Data Report, Ryan M. Manuel Feb 2019

Plant Community Composition And Structure Monitoring At Agate Fossil Beds National Monument, 2018 Data Report, Ryan M. Manuel

United States National Park Service: Publications

Abstract

This report presents the results of vegetation monitoring efforts in 2018 at Agate Fossil Beds National Monument (AGFO) by the Northern Great Plains Inventory and Monitoring Network (NGPN) and the Northern Great Plains Fire Effects Program (NGPFire). This was the eighth year of field work conducted by NGPN at AGFO.

In 2018, crew members from NGPN visited six long-term plant community monitoring (PCM) plots, four legacy plant community monitoring (LPCM) plots, and NGPFire visited one additional PCM plot to collect data on plant communities at AGFO. This collaborative effort is part of a long-term monitoring program established to better …
