1. Vegetation Classification and Information Standards
- www.fgdc.gov
- Vegetation Classification and Information Standards.
- OBJECTIVES: The overall objective of the Vegetation and Information Standards is to support the use of a consistent national vegetation classification system (NVCS) to produce uniform statistics in vegetation resources from vegetation cover data at the national level. ... Adoption of the Vegetation Classification and Information Standards in subsequent development and application of vegetation mapping schemes will facilitate the compilation of regional and national summaries. In turn, the consistent collection of such information will eventually support the detailed, quantitative, geo-referenced basis for vegetation cover modeling, mapping, and analysis at the field level.
- Fosters accuracy, consistency, and clarity in the structure, labeling, definition and application of a systematic vegetation taxonomy for the United States. ...
- Establishes a national set of standards for classifying existing vegetation cover and its associated information for the United States and its Trust Territories that will be used by Federal agencies to develop and report national statistics. This standard includes guiding principles, definitions of important terminology, and the National Vegetation Classification System (NVCS).
- Develops federal minimum metadata requirements to ensure consistent reporting on the status of our Nation's vegetation resources. Both the classification system and the metadata requirements may be used nationally to link local level vegetation inventory and map efforts.

2. ISEAM - KAZAKHSTAN - VEGETATION MONITORING
- gafweb.gaf.de
- VEGETATION MONITORING.
- In Kazakhstan there is considerable interest in the national monitoring of vegetation as animal husbandry has traditionally been the focus for rural livelihoods and economic activity. As the greater part of the country is totally arid, studies of changes in the nature and composition of the vegetation cover have now also become increasingly important for assessing the current status and monitoring the progression of desertification processes.
- Vegetation monitoring studies, using daily acquired, low resolution NOAA meteorological satellite imagery (AVHRR) over the whole country, are thus being implemented on the ISEAM project through the development of an information system adapted for local conditions. ...
- An important component of the analyses is the measurement of NDVI (normalized difference vegetation index) values which provide an indication of vegetation biomass, vigour and status. When studied on a daily basis or in chosen time period composites for the whole country, as well as in more detail for selected areas, significant trends and developments can be determined of interest to all those concerned with vegetation resources and related climatic influences. ... Significant changes can furthermore be analysed by reference to detailed investigations and classifications of vegetation, agriculture / land use and associated phenomena on higher resolution satellite imagery which can be correlated with the lower resolution AVHRR data. ...
- After undertaking in this area a wide range of multidisciplinary investigations, including extensive field work, a series of desertification maps have been produced to FAO specifications showing significant vegetation and other changes which have taken place over time, the current status and a future prediction of desertification processes. Digital forest and vegetation cover maps and associated databases have also been produced for Akmola Oblast and an extensive area of North East Kazakhstan which is of principal interest with regards to forestry and the incidence of fire damage. Spatial and statistical analyses of NDVI data are additionally being undertaken to investigate seasonal and national variations in vegetation cover and status. On the basis of these studies it is anticipated that a predictive capability can be established with respect to vegetation, climate and, for specific arable grain crops, yield assessment. ...

- Key to the vegetation classification system used in the atlas.
- The maps presented here are drawn from the coastlines of regional/continental maps in the Phillips World Atlas (Phillips, London 1986), with vegetation boundaries based on the range of sources cited in the literature survey. ... New Zealand is not presented in my maps because no commercially available atlas maps included it in sufficient detail on the same sheet as Australia/New Guinea, but the text description alone should suffice to give the reader an adequate impression of the past distribution of vegetation.
- Where the vegetation for a particular time slice is thought to have been generally very similar to that during another time slice, the maps are in effect combined. This should not be taken to imply that the vegetation everywhere in the region was absolutely identical to that which exists at the present, just that the known differences were so minor that they would scarcely be detectable on a map at this scale.
- The numbers of vegetation types on these maps correspond to the vegetation key. Where possible, abbreviated mnemonic codes for each vegetation type are also shown, to make the process of map interpretation somewhat easier.
- By 8,000 years ago - in the early Holocene - dense and woody vegetation had made a dramatic comeback. ...
