Post- Harvest Timber Stand Improvement Pea Ridge Conservation Area Comp #08

The Missouri Department of Conservation is soliciting bids for post-harvest timber stand improvement services at Pea Ridge Conservation Area, Compartment #08 in Washington County, with proposals due August 19, 2026. The contractor must hold a valid Missouri commercial pesticide applicator license before applying any chemicals on Department property and provide documentation of compliance upon request.

The scope encompasses herbicide application across five timber stands totaling approximately 58 acres: Stand 44 (11 acres), Stand 51 (9 acres), Stand 52 (12 acres), Stand 53 (11 acres), and Stand 66 (15 acres) located in Township 39N, Range 01E, Sections 19, 29, and 30. Work includes cut stump treatment and girdle (frill) treatment on specified tree species including sugar maple, red maple, elm, black gum, and Carolina buckthorn. Cut stump treatment applies to stumps of any size using spray nozzles or squirt bottles applied directly to the cambium layer year-round except during sap flow periods. Girdle treatment applies to stems 9 inches or greater in diameter using chainsaws to create cuts completely encircling the trunk, with herbicide application also restricted to non-sap flow periods. Acceptable herbicides are triclopyr ester, picloram, and 2,4-D solution; all applications require a noticeable dye additive for spot-checking. Herbicide applications must be applied within one hour of cutting and strictly adhere to product label instructions regarding solution ingredients, measurements, and flow rates. Application to non-target species or areas is prohibited.

Contractors must submit documentation of current and prior relevant experience, including client name and address, contact person details, service dates, dollar value, and service description. The Missouri Department of Conservation will conduct periodic inspections to ensure compliance with all contract standards.
