Mr. Palm is a fish biologist at the Swedish University of Agricultural sciences that has dedicated his past 14 years in the science of boulders, gravel, hydrology and brown trout. Most of his work have focused on the effects of in stream habitat restoration in streams and rivers in northern Sweden. His work has, however, also expanded in to the field of water chemistry as a limiting variable in lotic environments and fish migration. Due to the experience of two large scale restoration programs, and now starting a third one, his knowledge about the effects on early life stages of brown trout covers a wide range of aspects. When not working with fish, Mr. Palm also uses his knowledge to prevent negative effects off forestry on water quality and aquatic habitat by giving lectures to forest managers through the National Board of Forestry.
