Environmental correlates of the conservation value of boreal headwater streams and their riparian forests

Headwater streams and their riparian forests are considered as biodiversity hotspots and key habitats for the conservation of aquatic and terrestrial biota [1, 2]. However, most previous research has focused on single organism groups and studies providing a more comprehensive assessment of the conservation status of both stream and riparian fauna and flora do not exist. We used data ranging from near-pristine to strongly modified boreal headwater streams and their riparian forests to assess which in situ and larger scale environmental factors are the best determinants of the overall conservation value of sites. We then evaluated validity of the selected variables in predicting the conservat…
