Mar-Len Environmental, Inc.

Mar-Len Environmental, Inc., doing business as Mar LEN Environmental Inc., is a woman-owned small disadvantaged business based in Westminster, Maryland, that delivers forest management, habitat restoration, and environmental stewardship services to the Department of Defense as a prime contractor exclusively under small-business set-asides and full-and-open competitions. Mar-Len operates as a Subchapter S corporation and competes across Total Small Business, 8(a) competitive, and unrestricted solicitations, with the majority of recent work flowing through small-business-set-aside vehicles.

Mar-Len's capability portfolio centers on forest resource compliance, forest resource management, hazard tree removal, wildland fuel load reduction, forest inventory and stand enhancement, riparian buffer restoration, wetland mitigation monitoring, habitat maintenance for threatened and endangered species, stormwater management, and ecological restoration at military installations. Representative prime work includes a $2.49 million firm fixed-price delivery order from Army Installation Management Command Northeast Region for BMP stormwater management at Aberdeen Proving Ground (awarded September 2022, with completion in March 2024); a $665,649 delivery order for long-term wetland mitigation site monitoring under Clean Water Act compliance (awarded May 2025, completion May 2026); a $550,000 delivery order for forest stand rehabilitation and wildfire fuel load reduction across Aberdeen and Edgewood areas (awarded September 2025, completion September 2026); and multiple smaller delivery orders for forest inventory ($126,344), hazard tree removal ($264,552 for 105 trees across three APG locations), and invasive species removal ($200,956 for 28 acres).

Customer concentration is extreme and deliberate. The Army Installation Management Command Northeast Region accounts for 190 of 197 awards (100% coverage) and $66.4 million of the $68.1 million combined potential value across all awards. Three additional awards go to Army Installation Management Command Headquarters ($1.7 million), and one each to Army Materiel Command Army Contracting Command Aberdeen Proving Ground and Army Corps of Engineers Engineering District Baltimore. This vendor effectively operates as the sole provider of forestry support services to a single customer at a single installation: Aberdeen Proving Ground, Maryland. All work is performed at or in direct support of Aberdeen Proving Ground across the Aberdeen Area, Edgewood Area, and Churchville Test Area.

Mar-Len holds a single-award indefinite delivery contract (W56ZTN21D0001) with Army Installation Management Command Northeast Region valued at $9.1 million through February 2026 (subsequently updated to a new vehicle, W91ZLK10D0003 or successor, on March 3, 2026). A newly awarded IDC (W56ZTN26DA001), issued March 3, 2026, carries a $16.8 million ceiling through August 31, 2031 and is set aside for Total Small Business. The three primary parent vehicles generate task orders under forest resource compliance and forest resource management scopes. Task order frequency ranges from 77 orders under W91ZLK10D0003 ($5.5 million combined potential value) to 68 under W56ZTN16D0003 ($10.6 million) to 37 under W56ZTN21D0001 ($10 million).

Award activity has been consistent year-over-year: three awards in 2022, ten in 2023, eleven in 2024, and eleven in 2025. Only two awards appear in 2026 year-to-date (the new IDC and its initial delivery order). Seven awards carrying $1.6 million in combined potential value reach ultimate completion within the next twenty-four months, placing modest recompete exposure in near-term windows; the newly awarded 2026 IDC de-risks longer-term continuity. Combined potential value across all 197 awards stands at $68.1 million, with $28.7 million obligated to date (42% execution rate). Work is categorized almost entirely under NAICS 541712 (Support Activities for Forestry) and PSC Natural Resources/Conservation–Forest Tree Planting, with marginal engineering-services activity.

Mar-Len operates exclusively as a prime contractor; the source reports no subcontract activity. The vendor has maintained continuous SAM.gov registration and Aberdeen Proving Ground performance since 2002, functioning as the installation's embedded environmental management partner for forest stewardship, compliance, and ecological restoration across twenty-plus years of annual task orders.
