“…Flash floods that take place due to the inability of the watershed to control surface flow are ecologically and economically a serious threat for the long term in the future. 8 Land use is a human intervention both permanently and periodically to meet the needs of life both materially and spiritually, to the land resource complex. Land use patterns of an area can provide an overview of the economic life of the region concerned and at the same time can be used as an indicator of the level of environmental pollution so that there is an interest in providing more extensive land in order to develop a growing base of economies.…”

Background: The Lake Lindu sub-watershed has experienced environmental damage, mainly as a result of various activities of the surrounding community who are less aware of the principles of environmental sustainability. This study aims to determine the effect of land use area and environmental physical conditions on sedimentation and water debit in the Lake Lindu sub-watershed.Methods: This research was carried out by implementing survey and non-experimental method at 3 rivers: Langko (P1), Wongkodono (P2), and Kati (P3). The dependent variable in this study is the area of land use (area of farm, shrub, paddy field, forest, and settlement) and the physical condition of the environment (the width of the catchment area and annual average rainfall). Then, the independent variables are sedimentation and water debit. Statistical analysis used is a multiple regression model. Results: The results of this study are that the wider shrub (X2) reduces the sedimentation (Y1) and increases the water debit (Y2). Each addition of one shrub unit will reduce the sediment by 0.208 mg/L and affect the water debit of 0.258 m3/ s-1. The regression equation is Y1=185.903 - 0.208X2-587.269X8 and Y2=6.854+0.258 X2 - 71.708 X8. As for the coefficient of the shape of the river (X8). The bigger the shape of the river, the smaller the average of the water debit. Thus, each reduction of one coefficient unit of the river shape will affect the water debit of 71,708 m3 /s-1.Conclusions: The significant predictor factors for sedimentation and river water debit are the shrubs and the coefficient of the river shape.

“…Disturbance of soils and vegetation (surface disturbance) as a result of roads, pipelines, well pads and processing facilities fragments habitat (Weller, Thomson, Morton & Aplet, 2002) and denudes vegetation, leading to soil erosion and increased stream sediment load (Entrekin et al, 2011;McBroom, Thomas & Zhang, 2012;Reid, Metikosh & Ade, 2004). An existing research gap is if and how surface disturbance affects riparian and stream habitat and, thus, fish populations (Entrekin, Austin, Evans-White & Haggard, 2018). This research begins to address this information gap by evaluating aquatic habitat conditions and fish presence and abundance across sites with varying ONG development intensities.…”

Oil and natural gas (ONG) development can affect aquatic ecosystems through water contamination, water withdrawals and disturbance of soil and vegetation (surface disturbance) from infrastructure development. Research on how these potential sources of watershed and aquatic ecosystem impairment can affect fish assemblages is limited. Fish–habitat relationships were evaluated across stream sites experiencing differing levels of ONG development. Colorado River cutthroat trout, Oncorhynchus clarkii pleuriticus (Cope), and mottled sculpin, Cottus bairdii Girard, presence and abundance were associated with habitat conditions predominantly found in the less disturbed streams, such as higher proportion of shrub cover, greater stream depths and gravel substrate. Mountain sucker, Catostomus platyrhynchus (Cope), appeared to be a habitat generalist and was able to persist in a wide range of conditions, including degraded sites. Natural resource managers can use habitat preferences of these fish species to establish the development plans that mitigate negative effects of ONG development by protecting the aquatic habitats they rely upon.

A mechanistic understanding of ecological responses to land‐use change in headwater streams

Anthropogenic activities, such as oil and natural gas development (ONGD), have significantly altered the landscape. It is often challenging to identify the mechanistic processes underlying ecological responses to land‐use change (LUC). In aquatic ecosystems, alterations to habitat and food availability and water quality associated with increased LUC are key mechanistic pathways that deserve management consideration. We used structural equation modeling to evaluate how LUC associated with ONGD could influence macroinvertebrate and fish across 40 sites in six headwater streams in the Wyoming Range of the Upper Green River Basin, Wyoming. The most important mechanistic pathway varied, but responses were frequently driven by a direct effect of LUC or related to changes in food availability and water quality. Habitat complexity was the least important mechanistic pathway in our models. Our results also highlight that responses may reflect an organism's degree of habitat or resource specialization and/or sensitivity to changes in water quality. Habitat pathways were more important for habitat specialists (e.g., Mottled Sculpin, Cottus bairdii), food pathways were more important for food specialists (e.g., Colorado River Cutthroat Trout, Oncorhynchus clarki pleuriticus; Mountain Sucker, Catostomus platyrhynchus), and sensitivity to increased salinity was important for intolerant species (e.g., O. clarki, C. bairdii, and predatory macroinvertebrates). Continued identification of the specific mechanisms underlying species’ responses to increased LUC will aid in the conservation of ecologically and economically important species.
