Ecological solutions company Resource Environmental Solutions LLC received an investment from KKR investment firm. Financial terms were not disclosed, the company said June 27.

RES provides commercial solutions that help clients manage risk from operations in environmentally sensitive areas. RES’ environmental conservation and restoration activities include permitting restored wetlands, streams and species habitats to preserve land, enhance water quality and protect wildlife.

Since the company’s founding in 2007, several hundred companies including those in the oil and gas, petrochemicals and mining industries have worked with RES on their largest, most complex development projects. During that time, RES restored and conserved 155 miles of streams and more than 40,000 acres of wetlands in environmentally sensitive habitats.

New York-based KKR is making the investment from its eleventh Americas Private Equity investment fund.
