- The rate at which new information about stream resources is being created has accelerated with the recent development of spatial stream-network models (SSNMs), the growing availability of stream databases, and ongoing advances in geospatial science and computational efficiency. To further enhance information development, the National Stream Internet (NSI) project was developed as a means of providing a consistent, flexible analytical infrastructure that can be applied with many types of stream data anywhere in the country. A key part of that infrastructure is the NSI network, a digital GIS...AuthorsDavid E. Nagel, Erin Peterson, Daniel J.

- The height of woody plants is a defining characteristic of forest and shrubland ecosystems because height responds to climate, soil and disturbance history. Orbiting LiDAR instruments, Ice, Cloud and land Elevation Satellite-2 (ICESat-2) and Global Ecosystem Dynamics Investigation LiDAR (GEDI), can provide near-global datasets of plant height at plot-level resolution. We evaluate canopy height measurements from ICESat-2 and GEDI with high resolution airborne LiDAR in six study sites in different biomes from dryland shrub to tall forests, with mean canopy height across sites of 0.5-40 m....AuthorsQiuyan Yu, Michael G.

- Increasing wildfire frequency and severity in high‐elevation seasonal snow zones presents a considerable water resource management challenge across the western United States (U.S.). Wildfires can affect snowpack accumulation and melt patterns, altering the quantity and timing of runoff. While prior research has shown that wildfire generally increases snow melt rates and advances snow disappearance dates, uncertainties remain regarding variations across complex terrain and the energy balance between burned and unburned areas. Utilizing paired in situ data sources within the 2020 Cameron...AuthorsWyatt Reis, Daniel McGrath, Kelly J. Elder, Stephanie Kampf, David ReySourceWater Resources Research. 60: e2023WR036539.Year2024
- Droughts are often long-lasting phenomena, without a distinct start or end and with impacts cascading across sectors and systems, creating long-term legacies. Nevertheless, our current perceptions and management of droughts and their impacts are often event-based, which can limit the effective assessment of drought risks and reduction of drought impacts. Here, we advocate for changing this perspective and viewing drought as a hydrological-ecological-social continuum. We take a systems theory perspective and focus on how “memory” causes feedback and interactions between parts of the...AuthorsAnne F.

- Changes in the volume, rate, and timing of the snowmelt water pulse have profound implications for seasonal soil moisture, evapotranspiration (ET), groundwater recharge, and downstream water availability, especially in the context of climate change. Here, we present an empirical analysis of water available for runoff using five eddy covariance towers located in continental montane forests across a regional gradient of snow depth, precipitation seasonality, and aridity. We specifically investigated how energy-water asynchrony (i.e., snowmelt timing relative to atmospheric demand), surface...AuthorsRyan William Webb, John F.

- iFLOW is a free, open source, and python based framework and graphical user interface to visualize and analyze temperature time series, and extract one dimensional thermal velocity, vT, and bulk effective thermal diffusivity, ke. Information of thermal properties of the sediment water mixture (bulk) and water allows quantifying the one dimensional Darcian flux, q, and seepage velocity, v, from vT. Available software packages were developed to quantify q and ke only based on a specific mathematical model or focused on specific data processing or parameter estimation techniques, and all...AuthorsA.

- There is a pressing need for global monitoring of snow water equivalent (SWE) at high spatiotemporal resolution, and L-band (1-2 GHz) interferometric synthetic aperture radar (InSAR) holds promise. However, the technique has not seen extensive evaluation in forests. We evaluated this technique across varying forest canopy conditions using eight InSAR pairs collected at the Fraser Experimental Forest, Colorado, USA by NASA UAVSAR during the 10 week NASA SnowEx 2021 Campaign. Compared with in situ measurements, we found root mean squared errors (RMSEs) of 14-17 mm for SWE changes in forest...AuthorsR. Bonnell, Kelly J. Elder, D. McGrath, H. P. Marshall, B. Starr, N.

- This special issue of Rangeland Ecology and Management is dedicated to applying the Sagebrush Conservation Design (SCD) to improve conservation outcomes across the sagebrush biome in the face of pervasive ecosystem threats. This special issue provides new science and real-world examples of how we can implement the SCD to save a biome. The SCD is a tool to identify intact sagebrush areas and address the largest threats to the ecosystem. The SCD focuses on first protecting intact and functioning sage- brush ecosystems, called Core Sagebrush Areas, then works outward toward more degraded...AuthorsK. E. Doherty, J. Maestas, T.

- Rangelands are a type of land cover dominated by grasses, grass-like plants, broadleaf herbaceous plants (forbs), shrubs, and isolated trees, usually in which large herbivores evolved as part of the ecosystem. In many rangelands, the large herbivores were replaced by livestock, and thus livestock grazing represents a major land use for production of food and fiber. Sustainability is maintained by species diversity (Kouba et al., 2024; Retallack et al., 2023; Hooper et al., 2005; Tilman et al., 2006, 2012; Zaveleta et al., 2010; Reich et al., 2012) and reduction of biodiversity is expected...AuthorsE.

- While there are many definitions of rangeland, the central theme of all these is that it is land on which the dominating vegetation is mainly grasses, grass-like plants, forbs, shrubs and isolated trees (De Cauwer et al., 2024; Arogoundade et al., 2023; Feizizadeh et al., 2023; Sharifi and Felegari, 2023; McCord and Pilliod, 2022; Matongera et al., 2021; Zhou et al., 2020; Hadian et al., 2019; Al-bukhari et al., 2018; Eddy et al., 2017; Gökalp et al., 2017). Rangelands include shrublands, natural grasslands, woodlands, savannahs, tundra and many desert regions. A distinguishing factor of...AuthorsLalit Kumar, Priyakant Sinha, Jesslyn F. Brown, R.
