14. LARSE: Western Oregon Vegetation Mapping Project
- www.fsl.orst.edu
- Project Overview: Western Oregon Vegetation Mapping Project.
- Forest vegetation attributes should be mapped as continuous variables rather than classes, to maintain maximum flexibility for multiple end-users.
- Percent green vegetation cover (%GVC) .
- Relationships were examined between image spectral response and the following forest attributes (as measured in the reference plots): 1) Percent green vegetation cover (%GVC), 2) Percent conifer cover (%CC), 3) Conifer visible crown diameter (VCDm), and 4) Conifer age (AGEyr). ...
- This process was repeated for each remaining destination scene, and the separate pieces were then mosaicked to form a unified map layer for each of the four vegetation attributes.
- Predicted versus observed R2 and root-mean-square errors were calculated for each vegetation layer using an independent set of model validation plots. Additionally, a composite forest vegetation map was created, and a classification error matirx was generated.

- MADAGASCAR: Vegetation Mapping and Biodiversity Conservation (using Geographical Information Systems).
- Over 80% of the island has already been stripped of its native vegetation cover; the majority of this area is now very species-poor secondary grassland which is burnt annually and is subject to intense erosion. ... This unique diversity, combined with the threats to the remaining native vegetation, puts Madagascar amongst the highest conservation priority areas in the world. ...
- Our GIS studies in Madagascar are primarily aimed at analysing distribution patterns of vegetation types and plant biodiversity in Madagascar. Field work has shown that the structure and species composition of the vegetation often alters radically with changes in substrate. It is assumed, therefore, that different vegetation types, with different species compositions, occur on different rock types, and that a new, more informative map of vegetation types could be produced by subdividing the broad primary vegetation types on the basis of the rock type on which they occur. ...
- The first stage was to digitise the geology map of Madagascar (BESAIRIE, 1964), and then to simplify it into broad categories of rock types which seem to have an important effect on the vegetation they support. ...
- The remaining areas of good quality, primary vegetation were identified from the vegetation map of FARAMALALA (1988 &1995), which was derived from LANDSAT satellite imagery, and broadly maintained the vegetation zones defined by HUMBERT (1955). The primary vegetation was then classed into two major types, one evergreen (eastern and central) and the other deciduous (western and southern). ...
- A map of the ‘Remaining Primary Vegetation, classified by the Underlying Geology’ was produced by overlaying the map of ‘Remaining Primary Vegetation’ (derived from satellite imagery) on a map of ‘Simplified Geology’. This map provides new insights into the patterns of distributions of plant species, and the various types of vegetation, especially in western and southern Madagascar where the geology varies substantially. ...
- Histograms of the area remaining of each vegetation type (in km2) could then be produced, and by overlaying a map of the protected areas (COEFOR/CI, 1993), the amount of protection for each type could be demonstrated. It is immediately obvious which vegetation types are poorly represented in the current system of protected areas. ... If Reserves were set up on each category, then the system of reserves would include as wide a range of vegetation types as possible, and therefore as high a species diversity as possible. ...

- You can notice a marked deterioration in the condition of Iran in this map (a blue streak once existed indicating the healthiest vegetation, and now the entire Middle East, including Iran has gone downhill). The maps are assembled by computer based on satellite measurements and the way vegetation reflects certain wavelengths of light, with the greenest areas seeming to correspond to those places that received the most rains, based on my observations. ...
