Trait-based approaches to vegetation analyses are becoming more prevalent in studies of riparian vegetation dynamics, including responses to flow regulation, groundwater pumping, and climate change. These analyses require species trait data compiled from the literature and floras or original field measurements. Gathering such data makes trait-based research time intensive at best and impracticable in some cases. To support trait-based analysis of vegetation along the Colorado River through Grand Canyon, a data set of 20 biological traits and ecological affinities for 179 species occurring in that study area was compiled. This diverse flora shares species with many riparian areas in the western USA and includes species...

The South Atlantic Conservation Blueprint is a living spatial plan to conserve natural and cultural resources for future generations. It identifies shared conservation priorities across the South Atlantic region. The second iteration of the Blueprint, Version 2.0, was released in July 2015. It was a completely data-driven plan based on ecosystem indicator models for terrestrial, freshwater, and marine environments, as well as a connectivity analysis. Blueprint 2.0 used a 200 m spatial scale. With Version 2.0, the total number of people actively involved in developing the Blueprint grew to more than 400 individuals from over 100 organizations.

From 16 June to 30 July, 2021, a Virginia Tech team of 4-6 sampled the fish community in 30 Shenandoah Valley streams (Virginia and West Virginia, USA) as part of a larger stream-health study including other teams who surveyed geomorphology, water quality, flow, temperature, macroinvertebrates, and fish health at the same 30 streams. The fish community team also sampled three additional bonus streams (SiteID's FOLL, NAKE, and TUMB) during 19-22 August, 2021. These 33 streams had upstream drainage areas of 7 to 46 sq. km and included 4 James River tributaries (SiteID's POAG, MLRB, CEDR, PISG), one Potomac River tributary (HARL), and 28 Shenandoah River tributaries. At each stream, we sampled fish from two reaches...

High gradient streams and rivers of the Ozark Highlands were selected by the Gulf Coastal Plains and Ozarks (GCPO) Adaptation Science Management Team (ASMT) as a priority habitat system. The goal of this document discover and apply geospatial data and analysis to estimate the amount, configuration and condition of key habitat features of high gradient streams and rivers of the GCPO. The desired ecological state for priority habitat systems should characterize the least impacted condition – systems in this condition should be targets for maintenance/protection and the goal of restoration activities in degraded systems. In the GCPO Integrated Science Agenda (ISA), a general description of the desired ecological...
Small, surface-release dams are ubiquitous across the U.S. and have the potential to alter stream flow, impede sediment and nutrient transport, and fragment biotic assemblages. To mitigate these and other ecological impacts and reduce public safety hazards, dam removal has become an increasingly prevalent method of stream restoration. However, few streams have been consistently monitored before and after dam removal, and there is a need for more information regarding how dam removals affect stream ecosystems across different dam, stream, and watershed characteristics. The presented data aimed to quantify the effects of dams and dam removals on two critical water quality parameters (stream temperature and dissolved...
