This could be a very useful site for studying plant ecology and climatic trends. The data are based on available records from the IPCC Data Distributon Centre at the University of East Anglia. This site is by Andrew Gillen. These include forest clearing and reforestation in New England, natural fire and timber harvest in the Greater Yellowstone ecosystem, vegetative change in the arid Southwest, a continental perspective on the spread of exotic species, among other topics. This work provides perspective on large-scale ecological change and is quite thorough in its coverage of the pilot projects.
Detailled information is then available by species.
A wide assortment of techniques are presented at the site. Although some are outdated, much remains usable. This could be useful in beginning classes because this describes the same technology used to prepare most slides used in botany labs. This provides valuable access to archival holdings. This is an encyclopedic site on plant-associated fungi or mycorrhizas, specializing on but not restricted to, Australian plants.
