USDA Wildlife Services seeks scientific consultation specifically on Brown Tree Snake (BTS) and barrier testing, with details in the attached Performance Work Statement. Only respondents with direct experience in BTS biology, ecology, and locomotion will be acceptable because of the species’ unique climbing abilities. This is a market-research request for capability information only, not a solicitation; responses are voluntary and may help determine the acquisition method and possible small-business set-aside. Interested parties may submit capability statements including organizational details and UEI, tailored capabilities, and recent relevant past performance. The government will not reimburse costs or provide feedback/evaluations on submissions.
