The Cornell Botanic Garden's American Globeflower (Trollius laxus) Conservation Goals are as follows: (1) Preservation of genetic resources ex-situ. (2) Maintain viable American Globeflower populations within two Cornell Botanic Garden natural areas. These seeds are propagated in greenhouses yielding a 60% germination rate, grown for an additional two years under 50% shade and then outplanted in the fall of that given year. Previous research has revealed that the American Globeflower does not perform very well if it is shaded and doesn't perform well if it receives too much light. The preferred range is between 20% to 40% of available light. Same results were obtained by CORN while re-establishing populations that intermediate levels (LUX) yield very high population density. One of the challenges is many of these sites are becoming more shaded as tree growths occur so canopy thinning may be a consideration but may prove to be unnecessary as natural thinning is inevitable due to Hemlock Woolly Adelgid and Emerald Ash Borer devastating the Hemlock and Ash Tree population. In-situ conservations efforts are ongoing within two of Cornell's natural sites - a reintroduction program was initiated in 2012 to augment the population. A total of 344 propagated plants have been successfully introduced with a 90-95% survival rate. Valuable information obtained from the successful reintroduction of the globeflower will be applied to future projects. (Dunn. 2018)

The American Globeflower is currently listed as G3.  There exists 40 populations total with nearly 50% of populations located in one watershed (Dunn. 2018)

Excessive shading is suspected as the causal factor for this population decline. (Dunn. 2018)

37 populations of T. laxus ssp. laxus are known, these range from 5 to 3000 individuals. The largest population in 1983 3000 plants (NY); this same population had 2000 plants in 1980.

Loss of suitable habitat because of wetlands being drained, filled, or flooded for residential, commercial, or agricultural use. Natural succession of wetlands to woody vegetation Changes in the watershed by humans, beavers, or other sources Logging

Jones (2001) states that there are approximately 40 known occurrences of this species, all in eastern North America. Most of these occurrences have less than 100 individuals, and almost all have less than 1000 individuals.

From 1982-1985, research was conducted to determine seed germination and growth requirements, working with Ohio genotypes. (Parsons 1984)

Dr. Donald J. Leopold received a grant to study management of Trollius laxus ssp. laxus in central New York for two years beginning in 1991, but no publication was found. (Leopold 2001) Under the theory that removal of woody species shading the Trollius population would increase flowering, a section of one population was cleared in 1999. The cleared portion did not show the expected increase in number of plants or flowering plants by 2001, but further monitoring may be necessary (Faivre 2002)

As stated by Jones (2001), research and management needs include: Searches of appropriate habitat for historic and potentially new occurrences. Strive to achieve and maintain full genetic representation in the seed bank from known and new occurrences if they are found. Protect at least one site (with the larges known population) in Connecticut. Study the biology of the species in situ, including competition interactions and pollination biology, to help guide management strategies. Determine hydrologic processes that influence the vegetation composition and structure of wetlands that support this species. Continue work to clarify the full taxonomy of this species and members of the Trollius genus in North America.
