Diffuse Knapweed Biocontrol Photo Monitoring

In 2001, a photographic monitoring study was designed to evaluate the effectiveness of Larinus minutus biocontrol releases on diffuse knapweed infestations at the Rocky Flats Site.  The map below shows the location for each release site at Rocky Flats.  By clicking on any of the biocontrol release locations on the map, you can see the photographs of the diffuse knapweed infestations at that location.  Clicking on any photo will enlarge that photo.  Comparisons of the time-series photographs show visually how effective the biocontrol insects have been at reducing the overall diffuse knapweed populations at these locations.
