Combined core and corridor areas used to identify the landscape context of potential implementation opportunities in terms of enhancing functional connectivity. Data generated by The Conservation Fund as part of the Midwest Wind Energy Multi-Species Habitat Conservation Plan (MSHCP) and NiSource MSHCP green infrastructure network design processes.

Annapolis, MD: National Wildlife Federation.Executive SummaryThe impacts of climate change are already being felt in the Mid-Atlantic region. Coastal communities and habitats are threatened by sea level rise and an increasing frequency and severity of strong storms. Traditionally, gray infrastructure like seawalls and bulkheads have been used to protect coasts; however, these approaches disrupt intact ecological systems and exacerbate damage along adjacent shorelines. As a result, Natural and Nature-Based Features (NNBF) are increasingly being explored as a means of adapting to climate change while also...

This dataset describes streamflow and precipitation event statistics for four watersheds located in Clarksburg, Maryland, USA. Streamflow and precipitation events were identified from fourteen years of sub-daily (5- and 15-minute) monitoring data from October 1, 2004 through September 30, 2018. A 6-hour inter-event window was used to define discrete streamflow and precipitation events. The following streamflow metrics were calculated for each event area normalized peak streamflow, runoff yield, runoff ratio, streamflow duration, time to peak, and rise rate. Precipitation event metrics include total precipitation depth and precipitation event duration.

A rain garden and other stormwater control measures (SCM) were installed at Gary City Hall in Gary, Indiana to retain water, increase infiltration and divert stormwater from city sewers. These input data were collected from a rain gage ((USGS site 413611087201301, City Hall Weather Station at Gary, IN.) and five monitoring wells with installed pressure transducers at different locations (see site description). The Episodic Master Recession (EMR) method is applied using these data as the singular input to estimate the amount of groundwater recharge at each of the five sites during the indicated period of time.

Green infrastructure networks designed by The Conservation Fund for areas within the Mississippi River Basin. These green infrastructure networks were developed using the core-hub-corridor approach as follows. The building blocks of the network are “core areas” that contain well-functioning natural ecosystems that provide high-quality habitat for native plants and animals. By contrast, “hubs” are aggregations of core areas as well as nearby lands that contribute significantly to ecosystem services like clean water, flood control, carbon sequestration, and recreation opportunities. Finally, “corridors” are relatively linear features linking cores and hubs together, providing essential connectivity for animal, plant,...

A rain garden and other stormwater control measures (SCM) were installed at Gary City Hall in Gary, Indiana to retain water, increase infiltration and divert stormwater from city sewers. Input data were collected from a rain gage and five monitoring wells with installed pressure transducers at different locations (BFPK, CH1, CH2, CH3, GWPK; see site description). The Episodic Master Recession or EMR method (Heppner and Nimmo, 2005) is applied using these data as the singular input to estimate the amount of groundwater recharge at each of the five sites during the indicated period of time. References cited: Heppner, C.S., and Nimmo, J.R., 2005, A computer program for predicting recharge with a master recession curve:...

A rain garden and other stormwater control measures (SCM) were installed at Gary City Hall in Gary, Indiana to retain water, increase infiltration, and divert stormwater from city sewers. In order to investigate the impacts of the installed SCMs, hydrologic data were collected prior to and following the installation to estimate site water budgets (Lampe and others, 2022). The Episodic Master Recession (EMR) method was used to estimate recharge rates at five different locations for inclusion in the site water budgets (Heppner and Nimmo, 2005; Nimmo and others, 2015). Input data for the EMR software package were collected from a rain gage and five monitoring wells with installed pressure transducers at different locations...
