Larger and older SGs are more likely to
function as the last habitats of rare taxa,
which might have disappeared elsewhere.
However, small and derelict SGs may also
th l t b ti f l Rserve as the last bastions of several Rare
and Endangered organisms with limitedand Endangered organisms with limited
distribution ranges. g

Limitations & Constraints
Failed to identify many invertebrates (e.g. caddis flies, nematodes,
mites) due to
the unavailability of taxonomic expertise
Enlisting services of taxonomists for identifying specimens of even
the common taxa like fungi and nematodes was prohibited by
Fi i l t i t Financial constraints
Collection of spcies abundance data for birds and butterflies in Collection of spcies abundance data for birds and butterflies in
most of the SGs was incomplete … owing to

Tasks for Future Concerted SG Research
• Enlist the Services of Endangered Specialists –the Taxonomists.
• Expand the research focus to encompass Poorly Understood Taxa (e.g. Lichens, Nematodes))
• Inventory Representative Fauna (e.g. Lepidoptera and Vertebrates)
• Financial Support for Taxonomic Inventory of 20/12/10
• Financial Support for Taxonomic Inventory of SG Inhabitants
