This study employs the hedonic pricing method and a rich spatial and temporal dataset from two counties in Washington, USA to determine the effect of the 2009 Nisqually Restoration project (NRP) on housing prices in adjacent communities. The NRP restored 308 hectares of wetlands via dike removal in the Billy Frank Jr. Nisqually National Wildlife Refuge (NNWR), leading to improvements in salmon and bird abundance and recreational opportunities. We find that the ecological improvements made by the NRP increased the value of homes within 0.5 mile of the refuge by $37,631; homes 0.5 to 1 mile by $10,489; and homes 1 to 1.5 miles by $31,186. Our findings are consistent with previous wetland hedonic price analyses and...

Conclusions: Four plant species have been tested in the majority of field evaluations, while plants native to the test area and perennial plants are particularly underrepresented. Native plants useful in restoration of rare ecosystems can increase natural enemy abundance and provide ecosystem services as much as widely recommended non-natives. Thresholds/Learnings: Synopsis: The intentional provision of flowering plants and plant communities in managed landscapes to enhance natural enemies is termed habitat management and is a relatively new but growing aspect of conservation biology. The focus of most habitat management research has been on understanding the role of these plant-provided resources on natural enemy...
One anticipated benefit of ecosystem restoration is water quality improvement. This study evaluated NO3-N and phosphorus in subsurface waters during prairie establishment following decades of row-crop agriculture. A prairie seeding in late 2003 became established in 2006. Wells and suction cup samplers were monitored for NO3-N and phosphorus. Nitrate-N varied with time and landscape position. Non-detectable NO3-N concentrations became modal along ephemeral drainageways in 2006, when average concentrations in uplands first became <10 mg NO3-N L−1. This decline continued and upland groundwater averaged near 2 mg NO3-N L−1 after 2007. The longer time lag in NO3-N response in uplands was attributed to greater quantities...
