Ecological Restoration Case Studies
Rancocas Investments Wetland Mitigation Bank
>return to case studies
GreenVest has been the primary consultant responsible for design, approval, construction, and maintenance of the Rancocas Investments Wetland Mitigation Bank (RIWMB). Owned by the principals of GreenVest, the RIWMB encompasses approximately 400 acres of forested wetlands, forested uplands, and active agricultural lands. Credits were derived from wetland & upland preservation, wetland enhancement, and wetland restoration. A total of 30 credits will ultimately be available to offset permitted wetland impacts within New Jersey's Watershed Management Area #20 including Back Creek, Crosswicks Creek, Doctors Creek, Blacks Creek, Crafts Creek, and Assiscunk Creek within portions of Burlington, Mercer, Monmouth, and Ocean Counties.
The RIWMB is located in a rapidly developing region and represents one of the largest contiguous forested areas in northwestern Burlington County. The RIWMB includes a diverse array of habitat types such as old growth sweetgum-red maple swamp forest, old growth beech groves, green ash floodplain forest, vernal ponds, early successional forest, and scrub-shrub/emergent marsh. The large contiguous forested area and old-growth stands provide critical habitat for interior dwelling and cavity nesting species. One state listed plant species and one state listed reptile species have been confirmed within the property. Extensive stands of early successional forest were enhanced through selective thinning and plugging of agricultural ditches. Over 50 acres of prior converted agricultural fields have been restored by plugging ditches and recreating microtopographic variation. Phase I credits are fully sold. Contracts are pending for the sale of the balance of all bank credits.

Seasonally wet, prior converted agricultural fields such as the field depicted in this photograph will be restored by plugging ditches and recreating microtopography.

The RIWMB contains several vernal ponds that provide important breeding habitat for declining amphibian species in the region.

The RIWMB contains several stands of old growth sweetgum-red maple forest and beech forest. The old growth forest exhibits high vertical and horizontal stratification, contains many large diameter trees, and has large amounts of standing dead and coarse woody debris. These old-growth forests provide critical habitat for interior dwelling and cavity nesting species.

The RIWMB will ultimately contain over 400 acres of contiguous forested habitat and is one of the largest unfragmented forest areas remaining in northwestern Burlington County.
