Monarch CCAA
MPL proudly signed the Nationwide Candidate Conservation Agreement with Assurances (CCAA) for Monarch Butterflies on Energy and Transportation Lands, a unique collaboration between academia, regulators, and industry. This agreement underscores our commitment to enhancing biodiversity and supporting monarch butterfly populations. We achieve this by improving our rights-of-way to promote the growth of milkweed and nectar resources.
