Invasive Species Science Update (No. 7)

Publications Posted on: December 27, 2016
Invasive Species Science Updates are designed to keep managers and other users up-to-date with recently completed and ongoing research by RMRS scientists, as well as highlight breaking news related to invasive species issues.

Investigating new threats from emerging invasive plants

Science Spotlights Posted on: October 05, 2015
Forest Service scientists and partners developed an aggressive approach to investigate the biological and habitat characteristics of sickleweed (Falcaria vulgaris), a rapidly expanding invasive plant recently introduced into the grasslands of the northern Great Plains. Documenting patterns of invasion before species becomes widespread and identifying traits that may contribute to the success of recent invaders can increase our knowledge of factors influencing invasibility.

Inferring introduction history and spread of Falcaria vulgaris Bernh. (Apiaceae) in the United States based on herbarium records

Publications Posted on: September 17, 2013
Herbarium records were studied to infer the introduction history and spread of the exotic Eurasian sickleweed (Falcaria vulgaris Bernh.) in the United States. The spread of the plant was reconstructed using the location of early collections as the possible sites of primary introduction, and the location of subsequent collections as potential pathways along which this species spread.

Sickleweed on the Fort Pierre National Grasslands: An emerging threat

Publications Posted on: September 17, 2013
We report the first detailed field survey of sickleweed (Falcaria vulgaris L.) in the United States. Sickleweed is native to Europe, the Mediterranean, Asia Minor, and Iran and was first reported in the United States in 1922. It is listed by the Nebraska Invasive Species Council as a Category II invasive plant species.

Characterization of nuclear and chloroplast microsatellite markers for Falcaria vulgaris (Apiaceae)

Publications Posted on: September 17, 2013
Falcaria vulgaris (sickleweed) is native to Eurasia and a potential invasive plant of the United States. No molecular markers have been developed so far for sickleweed. Characterization of molecular markers for this plant would allow investigation into its population structure and biogeography thereby yielding insights into risk analysis and effective management practices of the plant.

Introduction history and population genetics of Falcaria vulgaris (Apiaceae) in the United States

Publications Posted on: September 17, 2013
Falcaria vulgaris Bernh. (sickleweed), native to Eurasia, occurs disjunctly in the Midwest and the East Coast of the United States. In parts of Iowa, Nebraska and South Dakota, it is an aggressive weed potentially turning to invasive.

Biology and ecology of sickleweed (Falcaria vulgaris) in the Fort Pierre National Grassland of South Dakota

Publications Posted on: September 19, 2011
In the last two decades the exotic plant sickleweed (Falcaria vulgaris Bernh., Apiaceae) has invaded, and come to dominate, large areas of the Fort Pierre National Grassland (FPNG) in central South Dakota, USA. Currently sickleweed is estimated to infest over 3200 ha of FPNG. The purpose of this study was to examine several of the biological and ecological traits that may contribute to the invasiveness of sickleweed in FPNG.
