Invasive.org is a joint project between University of Georgia's Bugwood Network and the U.S. Department of Agriculture. Over 8,300 images, including over 1,000 new images of invasive/exotic/noxious plant, insect, pathogen and other species (including many weeds) and their biological control agents, taken by over 250 photographers. Most images were digitized from high-resolution 35mm slides. Multiple levels of jpeg format images are downloadable and may be copied and used for any non-profit, educational purpose with appropriate credit and copyright notice. Although most images are North American in nature, the system also contains images of organisms that are "Non-U.S. Natives", or are considered to be "U.S. Invasives."
Flat Mites of the World provides a portal to a variety of keys, images, and fact sheets to help support identification of this diverse, potentially destructive group of mites.
Data from: Data on four criteria for targeting the placement of conservation buffers in agricultural landscapes
This article describes the data used to derive the values of attributes including soil erodibility, hydrological sensitivity, wildlife habitat, and impervious surface rate, and a scheme to classify the values in multi-criteria analysis of conservation buffer placement in the Raritan River Basin in New Jersey, USA.
The 2012 USDA Plant Hardiness Zone Map (PHZM) is the standard by which gardeners and growers can determine which plants are most likely to thrive at a location. The map is based on the average annual minimum winter temperature, divided into 10-degree F zones. For the first time, the map is available as an interactive GIS-based map, for which a broadband Internet connection is recommended, and as static images for those with slower Internet access. Users may also simply type in a ZIP Code and find the hardiness zone for that area. No posters of the USDA Plant Hardiness Zone Map have been printed. But state, regional, and national images of the map can be downloaded and printed in a variety of sizes and resolutions.
This website and on-line searchable database is a collaborative effort among several individuals. The arrangement of the specimen labels in the images on this site reflect their top to bottom positioning on the pin as viewed from upper left to lower right.
