Habitat Suitability Index

Evaluates (pond) habitat quality 10 suitability indices, all of which are factors known to affect great crested newts Combined index, between 0 and 1 –0 indicates unsuitable habitat –1 optimal habitat Ponds with higher index more likely to support great crested newts

Data collection & calculation of HSI 10 factors are scored for the pond Convert to SI scores ranging from (Do not give any SI score a value of 0) The 10 scores are then multiplied together The tenth root of this number is then calculated The calculated habitat suitability index should be between 1 and close to 0 H S I = (SI1 x SI2 x SI3 x SI4 x SI5 x SI6 x SI7x SI8 x SI9 x SI10) ^(1/10)

Categorisation of HSI scores HSIPond suitability <0.5Poor Below average Average Good >0.8Excellent

Geographic Location (SI-1)

Geographic location (SI-1)

Pond Area (SI-2)

Pond Permanence (SI-3)

Water Quality (SI-4) Water catchment/source Plenty of inverts Submerged vegetation Don’t confuse water clarity with quality

Water Quality CategorySICriteria Good1.0Abundant & diverse communities Netting = diverse inverts including mayfly larvae & water shrimps Moderate0.67Moderate invert diversity Poor0.33Low invert diversity (e.g.species such as midge and mosquito larvae), few submerged plants Bad0.01Clearly polluted, only pollution tolerant species (rat-tailed maggots), no submerged plants

Shading (SI-5) Estimate the % of perimeter shaded (usually by trees) Include trees that cast a shade to at least 1m from shore Does not include emergent vegetation Make estimate in May- end of Sept

Shading (SI-5) Heavily shaded ponds less likely to support great crested newt

Waterfowl (SI-6) Impacts waterfowl have on ponds and newts: Remove aquatic vegetation Pollute water Stir up sediments Some waterfowl actively hunt adult newts and larvae

Fish (SI 7)

CategorySICriteria Absent1 Possible0.67Possible Minor0.33Minor (Crucian Carp & sticklebacks) Major0.01Major (other species or carp/sticklebacks in dense populations)

Pond Count (density) (SI-8) Higher pond densities – more likely to support great crested newt

Terrestrial Habitat (SI-9) Good terrestrial habitat offers- cover, foraging opportunities Habitat includes meadow, rough grassland, hedges, scrub, woodland and gardens

CategorySICriteria Good1Extensive area of habitat offering good areas for foraging and shelter. > 75% of available area Moderate0.67Habitat offers opportunities for foraging and shelter % of available area Poor0.33Habitat offers little opportunity for foraging and shelter < 25% of area None0.01No suitable habitat around the pond
