GIS AND CONSERVATION
Conservation
biologists have come to recognize the importance of GIS in their domain.
Geographic Information Systems (GIS) has become a most effective tool in the field of
landscape ecology. With the
increase in available landscape data from satellite imagery and public agencies
(like NRSC), GIS has established a niche in the field of biodiversity conservation for spatial analyses. Some important topics where the tool finds application are below:
Gap Analysis
An area where
GIS found early application is gap analysis. Gap Analysis is the process of mapping out
sensitive species habitats and overlaying the protected and undisturbed areas
of habitat. This allows conservation biologists to visualize areas of sensitive
species that are currently unprotected.
GIS and Corridor Mapping
Over the recent years,
GIS has found great use in mapping of corridors. These corridors when
identified are restored for the effective migration of different terrestrial
species. Corridors connect habitats cut off due to anthropogenic factors (like
agriculture, construction of roads etc.). Corridor restoration is important for
species having large home range in order to reduce human-wildlife conflict.
Land cover- Land use Mapping
Another key area where
GIS is gaining wide application is the mapping of land use-land cover changes. Due
to various human induced factors landscape structure has been constantly
changing for the worse so far as wildlife conservation is concerned. The
availability of satellite images for a landscape enables one to monitor the
spatio-temporal changes and thus future projection is made. Bassed on these
future projections, steps are taken by decision makers.

ReplyDeleteits good.really hard to click that image,landscape fragmentation is very visible in that image
Delete@ Suchithra: Actually I took this pic. from an aircraft minutes b4 landing.Was fortunate enough that it was not cloudy.
DeleteGIS is helping more in landscape ecology...... nice
ReplyDeletegood one ..............dr
ReplyDeletenice topic
ReplyDeleteproper description and picture speaks more
ReplyDeleteGIS is indeed needed and essentail for decision making in every field

ReplyDeleteif one of the analysis maps were included it could've been really gr8..but its still good :)
