Wetlands are important because they are biodiversity hotspots and support iconic wildlife. They also provide valuable “ecosystem services,” such as flood attenuation and storage, aquifer discharge and recharge, sediment stabilization and sequestration, carbon storage, water quality enhancement, and nutrient cycling. Wetlands also provide important...

Context 1
... specifically for Rocky Mountain National Park, humans have directly and indirectly affected wetlands since before the park was established and during its early operations ( Figure 9). Direct human alterations of hydrologic processes in the park include small scale features such as water supply reservoirs and drainage ditches, and, more significantly, large scale diversions that influence around 44% of the park's area. ...
Context 2
... present hydrologic indicators in the following sections. First, we present baseline data from all sites using instantaneous summer hand measured depth to water from ground surface (DTW, also referred to as groundwater or water table depth; Figure 49). Results are given across all sites (including spatially) and at the parkwide scale from our representative survey. ...

... SE = standard error, LCB and UCB = lower and upper bounds on a 95% confidence interval. Figure 90 and Figure 91 show the CDFs of groundwater specific conductance and pH (respectively) across the park. A CDF describes the 'value so far' of cumulative conductance or pH from the lowest to highest score, moving from left to right. ...

... the early 1900s several homesteaders established Holzwarth Trout Lodge and Hotel de Hardscrabble, both primitive but successful dude ranches. These were later replaced by the Never Summer Ranch ( Figure B9) and Phantom Valley Ranch, respectively, which hosted guests until the 1970s. Hunting, fishing and trapping, along with increases in human populations and subsequent species reintroductions, may have contributed to changes in animal populations that persist today ( Ziegenfuss et al. 2002). ...
