red clover flower 113867 640The Mountain Invasion Research Network (MIREN) is performing a global survey of invasive plant species distributions along mountain trails - and they need your help!

MIREN is calling on mountain scientists worldwide to join them in their study of invasive plant species this summer. Through their global trail survey, MIREN hopes to study the spread of invasive plants along mountain trails in order to understand where and how quickly these species are traveling. They also aim to understand what defines a species' current limits along mountain trails in both their native and invasive range. 

Participation is easy: All you need is a GPS or smartphone to submit your observations, and a willingness to walk mountain trails!
