Research with ferns began in 1990 with studies on the reproductive biology of Alaska's only endangered plant species, the Aleutian shield-fern. We contributed to the recovery plan of this species by developing a protocol for tissue culture propagation should the natural populations decline. We also have conducted hardiness trials for native and introduced garden ferns and have developed a list of recommended ferns for home and commercial landscapes.
