“…as rainout, moisture transport, and evaporation (Aron et al, 2021). The Intermountain West of the United States, often defined to include Idaho, Nevada, Utah, much of western Colorado, New Mexico, northern Arizona, western Montana, and Wyoming, is home to approximately 20 million people, supports extensive rangelands (250 million acres) and irrigated agriculture (10 million acres), and contains vast regions of wilderness and public lands (335 million acres) (Brice et al, 2020). Understanding the hydroclimate in this region is critical to sustainability efforts and requires long-term integrated research on cycling of carbon, nutrients, and water through the ecosystem.…”

The Reynolds Creek Experimental Watershed (RCEW) and Critical Zone Observatory (CZO), located south of the western Snake River Plain in the Intermountain West of the United States, is the site of over 60 years of research aimed at understanding integrated earth processes in a semi‐arid climate to aid sustainable use of environmental resources. Meteoric water lines (MWLs) are used to interpret hydrologic processes, though equilibrium and nonequilibrium processes affect the linear function and can reveal seasonal and climatological effects, necessitating the development of local meteoric water lines (LMWLs). At RCEW‐CZO, an RCEW LMWL was developed using non‐volume‐weighted, orthogonal regression with assumed error in both predictor and response variables from several years of precipitation (2015, 2017, 2019, 2020, and 2021) primarily at three different elevations (1203, 1585, and 2043 m). As most precipitation is evaporated or intercepted by vegetation in the driest months, an RCEW LMWL for groundwater recharge (RCEW LMWL‐GWR) was also developed using precipitation from the wettest months (November through April). The RCEW LMWL (δ2H = 7.41 × δ18O – 3.09) is different from the RCEW LMWL‐GWR (δ2H = 8.21 × δ18O + 9.95) and compares favorably to other LMWLs developed for the region and climate. Comparative surface, spring, and subsurface water datasets within the RCEW‐CZO are more similar to precipitation during the wettest months than dry months, illustrating that some semi‐arid hydrologic systems may most appropriately be compared to MWLs developed from precipitation only from the wettest season.

“…This abundance of remote sensing data allows grazingland managers to address a series of probing research questions related to past, present, and future landscape conditions [13,14]. The advanced very high-resolution radiometer (AVHRR) has been used in the past to estimate net primary production on grazinglands at a 1 km 2 resolution [15].…”

“…As climate change and desertification continues to be an ever-pressing concern, geospatial analyses focusing on their extent and effects upon grassland management will become increasingly important [13,110,111]. Research from the US has shown the potential for increased grazingland production in the northern Great Plains from increasing temperatures due to climate change, while the southwestern US will most likely face severe reductions in biomass production [112,113].…”

Perspectives on the Special Issue for Applications of Remote Sensing for Livestock and Grazingland Management

et al. 2022

The use of geospatial sciences and technologies for the management of grazinglands has fostered a plethora of applications related to ecology, wildlife, vegetation science, forage productivity and quality, and animal husbandry. Some of the earliest use of remote sensing dates to the proliferation of aerial photography in the 1930s. Today, remote sensing using satellite imagery, global navigation satellite systems (GNSS), and internet-connected devices and sensors allow for real- and near real-time modeling and observation of grazingland resources. In this special issue of Remote Sensing, we introduce nine original publications focusing on varying aspects of grazingland management, such as animal health and telemetry, climate change, soil moisture, herbaceous biomass, and vegetation phenology. The work in this issue spans a diverse range of scale from satellite to unmanned aerial systems imagery, as well as ground-based measurements from mounted cameras, telemetry devices, and datalogging devices. Remote sensing-based technologies continue to evolve, allowing us to address critical issues facing grazingland management such as climate change, restoration, forage abundance and quality, and animal behavior, production, and welfare.

“…The rapidly changing patterns in temperature and precipitation predicted by climate models over the next century are increasing pressure to change our approach to land use and land management [ 1 , 2 ]. It is expected that arid zones will expand [ 3 ] and levels of soil salinity will increase in certain areas [ 4 ], both of which will have significant negative impacts on agriculture and food production.…”

Few phytoremediation studies have been conducted under semi-arid conditions where plants are subjected to drought and/or salinity stress. Although the genus Salix is frequently used in phytoremediation, information regarding its tolerance of drought and salinity is limited. In the present study, Salix acmophylla Boiss. cuttings from three sites (Adom, Darom and Mea She’arim) were tested for tolerance to salinity stress by growing them hydroponically under either control or increasing NaCl concentrations corresponding to electrical conductivities of 3 and 6 dS m−1 in a 42-day greenhouse trial. Gas exchange parameters, chlorophyll fluorescence and concentration, and water-use efficiency were measured weekly and biomass was collected at the end of the trial. Root, leaf and stem productivity was significantly reduced in the Adom ecotype, suggesting that Darom and Mea She’arim are the more salt-tolerant of the three ecotypes. Net assimilation and stomatal conductance rates in salt-treated Adom were significantly reduced by the last week of the trial, coinciding with reduced intrinsic water use efficiency and chlorophyll a content and greater stomatal aperture. In contrast, early reductions in stomatal conductance and stomatal aperture in Darom and Mea She’arim stabilized, together with pigment concentrations, especially carotenoids. These results suggest that Darom and Mea She’arim are more tolerant to salt than Adom, and provide further phenotypic support to the recently published data demonstrating their genetic similarities and their usefulness in phytoremediation under saline conditions.
