Baseline Water Quality Monitoring to support restoration efforts in the Cache Slough Complex, 2013-2021.
The Cache Slough Complex is an ecologically significant area, with many restoration efforts of various kinds set to take place within its boundaries. These efforts which are tied to regulations set forth by the Biological Opinion, will have unknown impacts to in‐stream water quality. For this reason, the Department of Water Resources’ Water Quality Assessment (WQA) unit developed a monitoring program to establish baseline water quality measurements to help understand the environmental impact of these restoration projects and ensure pre‐restoration water quality data is available to compare against post-restoration water quality. To do so, data was collected at various sites that represent all major inputs and outflows within the Cache Slough Complex from September 2013 to December 2021.
A case study of the effects of wetland restoration on the hydrology, species diversity, species composition and floristic quality of restored wetlands within a Central Florida ranchland, 2003 - ongoing.
In the USA the United States Department of Agriculture (USDA) Natural Resource Conservation Service (NRCS) has restored millions of acres of wetlands through its Wetland Reserve Easement (WRE) programs. However few quantitative studies have explored whether WREs have enhanced wetland hydrology and wetland plant communities. Additionally USDA Compatible Use Permits for cattle grazing and other management practices are sometimes issued for WREs but little is known about potential benefits/detriments of such practice on the success of wetland restoration. In this study we tested if hydrological restoration of previously drained species poor pastures increased water depth and hydroperiod. Restoration involved plugging key ditches adding water control structures and a berm. We also tested if hydrological restoration increased plant diversity (alpha and beta) floristic quality (using coefficient of conservatism) and increased the cover of wetland species (using species wetland status). Finally we tested if cattle grazing had an effect on the success of restoration by comparing grazed plots to fenced plots. We studied two conservation easements (a total of 748 acres) located on semi-native pastures in central Florida USA. We monitored vegetation using permanent transects stratified by vegetation type before (2004-2005) and after (2012) the restoration (2008). We assessed wetland hydroperiod using groundwater wells set up in 2003 and located within and outside the boundaries of these two easements.
Landscape Corridors Promote Long Distance Seed Dispersal by Birds During Winter but Not During Summer at an Experimentally Fragmented Restoration Site
In fragmented landscapes, plant population persistence and community diversity can hinge upon plants dispersing seeds long distances between isolated patches of habitat. Landscape corridors, which connect otherwise isolated patches, have been shown to increase seed dispersal by birds moving between patch fragments. However, because bird behaviors change seasonally, the strength of this "corridor effect" may also change. We assessed the utility of corridors for promoting seed dispersal by birds during both summer and winter in a well-replicated corridor experiment conducted in early successional longleaf pine (Pinus palustris) savannah habitat at the Savannah River Site in South Carolina, USA. We used a single species of bird-dispersed fruiting plant, American black nightshade (Solanum americanum), and controlled the timing and number of fruits available to birds during summer and winter. Corridors increased long-distance seed dispersal during winter but not during summer, indicating that the effectiveness of corridors for promoting long-distance seed dispersal can depend upon plant reproductive timing and seasonal differences in bird movement. A better understanding of the seasonality of plant-animal interactions will permit better predictions about whether and how corridors provide connectivity for plants.
Long Term Research in Environmental Biology (LTREB): California vernal pool plant community ecology and restoration, 2000-2017
This data set includes annual vegetation data and selected water depth data collected during the period 2000-2017 from vernal pool basins that were constructed in 1999 as part of a large-scale vernal pool mitigation effort at Travis Air Force Base, California. The constructed pools covered an area of about 15 Ha and were located adjacent to a complex of naturally-occurring pools, which were used as reference sites for comparison. Five plant species were intentionally seeded into the pools according to five seeding treatment protocols to assess the influence of order of colonization, frequency of colonization, and dispersal limitation on vernal pool plant community assembly. Because water depth was known to influence plant species distributions, water depth was recorded weekly during the winter wet season in selected years for each constructed and reference pool at the site. Seed plots were 50 cm x 50 cm and were permanently marked and used for repeated sampling of vegetation from 2000-2017. For each plant species that occurred in the plots, the frequency of occurrence was recorded as the number of squares out of a 100-cell grid laid over the plot in which that plant species appeared. For the five species that were planted into the plots, the frequency was recorded, as above, but in addition the number of individuals of that species in the plot was also recorded.
Seeing the light: nitrate spiraling and hydrogeomorphic characteristics of restored and unrestored streams in the Baltimore, MD region.
The continually increasing global population residing in urban landscapes impacts numerous ecosystem functions and services provided by urban streams. Urban stream restoration is often employed to offset these impacts and conserve or enhance the various functions and services these streams provide. Despite the assumption that ‘if you build it, [the function] will come’, current understanding of the effects of urban stream restoration on stream ecosystem functions are based on short term studies which may not capture variation in restoration effectiveness over time. We quantified the impact of stream restoration on nutrient and energy dynamics of urban streams by studying 10 urban stream reaches (five restored, five unrestored) in the Baltimore, Maryland, USA, region over a two-year period. We measured gross primary production (GPP) and ecosystem respiration (ER) at the whole-stream scale continuously throughout the study and nitrate (NO3-N) spiraling rates seasonally (spring, summer, autumn) across all reaches. There was no significant restoration effect on NO3-N spiraling across reaches. However, there was a significant canopy cover effect on NO3-N spiraling, and directly comparing paired sets of unrestored-restored reaches showed that restoration does affect NO3-N spiraling after accounting for other environmental variation. Furthermore, there was a change in GPP:ER seasonality, with restored and open-canopied reaches exhibiting higher GPP:ER during summer. The restoration effect, though, appears contingent upon altered canopy cover, which is likely to be a temporary effect of restoration and is a driver of multiple ecosystem services, e.g., habitat, riparian nutrient processing. Our results suggest that decision-making about stream restoration, including evaluations of nutrient benefits, clearly needs to consider spatial and temporal dynamics of canopy cover and tradeoffs among multiple ecosystem services.

Assessing the use of bison for savanna restoration at Cedar Creek Ecosystem Science Reserve: Oak sapling growth
Oak savanna is the most threatened ecosystem in Minnesota and fire, alone, is not restoring and preserving it. Our savanna restoration research started more than a half century ago in what had once been native savanna at Cedar Creek. It has shown that burning about 4 to 7 times per decade eliminates shrubs and non-savanna tree species and restores prairie grassland species. However, our 50 years of research is also showing that these frequent and intense fires are preventing oaks from regenerating. Bison are now known to be a keystone species for restoring and preserving grasslands, but their roles in savanna ecosystems remain unknown. In grasslands, bison preferentially graze the dominant warm season grasses that would otherwise outcompete wildflowers, thereby promoting plant coexistence and enhancing plant diversity. Here we propose to test whether bison grazing might promote the growth and survivorship of oak seedlings in burned savannas by reducing grass fuel for fires and by knocking back dominant grass competitors. We will maintain the existing fire frequencies and the design of the long-term burning experiment, while adding bison grazing as an additional factor in part of several burn units on the southeast side of the property. Bison will graze during the summer and early fall seasons. Grazing exclosures will be established, and oak seedlings will be planted, to test effects of bison grazing on early oak growth and survivorship. The outcomes we plan to achieve are to: (1) discover better restoration and preservation practices for savanna ecosystems; (2) determine how these practices impact savanna biodiversity; and (3) educate Minnesotans about the ecological heritage of their state, including the roles that bison, fire and biodiversity play in the functioning of savannas and other Minnesota ecosystems. We will achieve these goals and outcomes by: (1) restoring bison grazing to 200 acres of oak savanna; (2) experimentally testing whether bison grazing promot
Gunnison's Prairie Dog Restoration Experiment (GPDREx): Small Mammal Mark-Recapture Population Assessment within Grasslands at the Sevilleta National Widlife Refuge, New Mexico (2013-2014)
Prairie dogs (Cynomys spp.) are burrowing rodents considered to be ecosystem engineers and keystone species of the central grasslands of North America. Yet, prairie dog populations have declined by an estimated 98% throughout their historic range. This dramatic decline has resulted in the widespread loss of their important ecological role throughout this grassland system. The 92,060 ha Sevilleta NWR in central New Mexico includes more than 54,000 ha of native grassland. Gunnison’s prairie dogs (C. gunnisoni) were reported to occupy ~15,000 ha of what is now the SNWR during the 1960’s, prior to their systematic eradication. In 2010, we collaborated with local agencies and conservation organizations to restore the functional role of prairie dogs to the grassland system. Gunnison’s prairie dogs were reintroduced to a site that was occupied by prairie dogs 40 years ago.  This work is part of a larger, long-term study where we are studying the ecological effects of prairie dogs as they re-colonize the grassland ecosystem. With this project, we would like to further investigate the impact that Gunnison’s prairie dogs have on the landscape. Gunnison’s prairie dog monitoring data has been collected from the beginning of the reintroduction project, but little information has been collected on how grassland species respond to the sudden presence of prairie dogs on the refuge. This project will help determine if the prairie dog reintroduction has had positive impacts on the grassland ecosystem. Prairie dogs benefit grasslands in many ways, but their role as ecosystem engineers directly impacts other species by creating new habitat that would not be present without prairie dogs. We have documented physical landscape changes, but we have not specifically documented benefits to other grassland species. This work will help determine if the reintroduced prairie dog populations on Sevilleta NWR are now acting as a keystone species in a grassland ecosystem by monitor
