MBS 30th Anniversary!
For 30 years, biologists with MBS have been combing the state, looking for remnants of native vegetation and rare plant and animal species. Check out the anniversary page for a look at our progress!
Aquatic Survey Update
MBS is known for assessing prairies and forests, but did you know we also study 'hidden forests' in lakes and rivers. MBS Plant Survey Supervisor, Hannah Texler, provided an aquatic plant team update!
