Streams in the Catskill Mountains region of New York provide many important ecological and economic services, including recreational angling and serving as a drinking water supply to New York City. Many streams in this region were adversely affected by acid deposition during the late 20th century, impairing water quality and aquatic ecosystems. More recently, the level of acid deposition has declined while changes in climate have become more pronounced. As a result, biological and chemical data are needed to determine the current condition of stream ecosystems in the Catskill Mountains region. The U.S. Geological Survey, in cooperation with the Rondout Neversink Stream Program, surveyed fish communities and water chemistry annually between 2017 and 2019 at 23 sites in the upper Neversink River and upper Rondout Creek watersheds to compile a contemporary baseline dataset and assess potential biological recovery from reduced acidification. The resulting data indicated that brook trout (Salvelinus fontinalis) were present at every study site, although slimy sculpin (Cottus cognatus) was the most abundant species at most sites. Stream pH ranged from 4.8 to 7.0 across all sites and generally increased from upstream to downstream. Similarly, the number of species present and the ratio of brown trout (Salmo trutta) to brook trout increased at sites in each subwatershed from upstream to downstream. Introduction The Neversink River and Rondout Creek are historic trout fishing and recreational streams in the heart of the Catskill Mountains of southeastern New York. Both streams played an important role in the origins of fly fishing in the United States, and continue to be used heavily by anglers (Van Put, 2007). During the second half of the 20th century, however, the headwaters, tributaries, and some main stem reaches of both rivers were adversely affected by acid deposition. Surveys during the late 1980s and early 1990s found that some or all fish species were absent or their populations were depressed in many reaches of both river systems because of elevated acidity and concentrations of inorganic monomeric aluminum compounds (Baker and others, 1996; Baldigo and Lawrence, 2000, 2001). More recently, acid deposition and stream acidity have declined in the Catskill Mountains region (McHale and others, 2017), and climate change is an increasing threat that is affecting stream flow and temperature regimes across the northeastern United States (DupignyGiroux and others, 2018). Quantitative information on fish assemblages in the Catskill Mountains region is needed to assess the current health of stream ecosystems, evaluate potential biological recovery from decreasing acidification, and document the effects of climate change, invasive species, and other stressors on important natural resources. In 2017, the U.S. Geological Survey (USGS) and the Rondout Neversink Stream Program initiated a study to determine the current status of fish assemblages and water che

Surveys for coastal Cactus Wren ( Campylorhynchus brunneicapillus ) were done in 378 established plots in southern San Diego County in 2020, encompassing three genetic clusters (Otay, Lake Jennings, and Sweetwater/ Encanto genetic clusters). Two surveys were completed at each plot between March 1 and July 31. Cactus Wrens were detected in 131 plots (35 percent of plots). This is a slight increase over the proportion of occupied plots in 2019. One hundred and nine Cactus Wren territories were detected across all survey plots in 2020, an increase from 83 in 2019. At least 85 percent of Cactus Wren territories were occupied by pairs, and 62 fledglings were observed in 2020. There were 89 color-banded Cactus Wrens observed in 2020, 84 of which we could identify to individual. Adults of known age ranged from 1 to at least 6 years old. Adult Cactus Wrens moved on average 0.2 kilometers (km; maximum 3.8 km) from their 2019 territories to their 2020 territories. Cactus Wrens that fledged in 2019 moved on average 1.2 km (maximum 9.9 km) to their 2020 territories. No known-identity Cactus Wrens moved between genetic clusters from 2019 to 2020. Vegetation at Cactus Wren plots typically was dominated by coastal sage scrub shrubs such as California sagebrush ( Artemisia californica ), lemonadeberry ( Rhus integrifolia ), California buckwheat ( Eriogonum fasciculatum ), and broom baccharis ( Baccharis sarothroides ). Very little dead or unhealthy cactus was observed within Cactus Wren survey plots. Thirty-eight percent of plots had at least 25 percent of the cactus crowded or overtopped by vines and shrubs. Non-native annual cover was greater than 25 percent at 35 percent of plots.

Groundwater levels and surface-water flow measurements were collected from August 2016 to September 2018 to provide the Mason Conservation District and other stakeholders with basic knowledge of existing water resources in Mason County, Washington. Additionally, the data were collected with the intent of contributing to informed decision making about groundwater use, management, and conservation throughout the county and for future inclusion in a groundwater model. Data were collected and compiled for 130 sites—110 wells and 20 miscellaneous surface-water discharge sites. In spring 2016, field reconnaissance was conducted to locate suitable locations for baseflow discharge measurements to be used for estimating groundwater contribution to surface flow. In summer 2016, a field inventory of wells was conducted to acquire locational data and to assess the suitability of the wells for inclusion in a monthly groundwater-level monitoring network. Groundwater levels were measured bimonthly in the 64 wells over 2 years. Streamflow measurements were conducted two times each summer during two summers for each of the 20 surface-water sites. a numerical to
