Major threats to swamps
• Altering natural hydrologic regimes
• Pollution, introduction of exotic/invasive
species
• Land use change
• Pollinator decline
• Problems in seed dispersion
• Over harvesting of resources
Objectives
• Ecological restoration of Myristica swamps in Uttara
Kannada district, central Western Ghats India.
• Characterizing the swamp fragments and micro-corridors for
species composition, resource use, develop an enrichment
protocol for each of the micro-corridor with respect to the
species, frequency and geometry of planting
• Create micro-corridors by enrichment planting through
participatory approach, creation of new swamp populations habitat recovery
• Achieve a lasting restoration of the swamps
Methods
• Identification and mapping of the fresh water
swamps
• Identify critical micro-corridors to link the
swamp fragments
• Detailed vegetation survey, listing of
obligatory species and facultative swamp
species, regeneration and demographic
studies.
• Standardizing protocol for propagation of
swamp species through participatory approach
• Decentralized community nurseries near the
swamp forests in three villages
• Active planting of degraded swamps with
obligatory, facultative and associated species was
done during period from 2010-2012
• Survival and growth rates assessed
• Re-wetting of the land through installing soil and
moisture conservation structures in the degraded
swamps
• Activities to ensure community participation
in restoration and management
• Classification of swamps based on physical
characteristics and vegetation elements to
suggest effective management plans for the
swamps
• Soil and hydrological studies
Results
• 102 swamps were identified in the district fifteen swamps in Sharavati river catchment
• Twenty in Bilgi hole
• Seventeen in Bedti
• Twenty five in Aghanashini
• Twenty three in Mukti hole
• Total depression part of swamp area
documented is about 82 hectares
Results
• 156 swamp species and associated were
documented.
• 15 species of lianas, 5 species of climbers, 24
species of shrub and 104 species of trees
occur in the swamp area.
• Frequency, geometry and spatial dispersion of
the obligatory swamp species was carefully
noted.

• Ten thousand seedlings planted
• Commercially important and RET forest
species were raised
• Survival rate - obligatory swamp species was
56 percent and facultative and associate
swamp species was 64 percent
