  abstract = {{I}ncreased frequency and intensity of anomalies in climate change ultimately affect soil health and are heightened in biodiverse areas of extreme gradients, thus effecting soil biodiversity in the {H}imalayas. {T}he current study investigates diversity of soil nematodes, in free living ({FLN}) and plant parasitic groups ({PPN}) associated with {H}imalayan vegetation and shows their relationships with soil physicochemical parameters (p{H}, moisture content, nitrogen, soil organic matter and soil organic carbon) in this previously unsurveyed region. {S}amples were taken randomly from four sub sampling sites in 20 km2 average areas of ten districts using the {S}outhy method. {N}ematode isolation was performed using the {C}obb sieving and decantation method, and modified {B}earmann's funnel technique. {C}ommunity indices of each site's vegetation were calculated and subjected to statistical analysis-{P}rincipal {C}omponent analysis ({PCA}) and {M}ultiblock {P}artial {L}east {S}quares ({MBPLS}). {MBPLS} analysis illustrated associations of organic-matter and nitrogen content with mixed-cropping and p{H} in soil with grassland, alpine-forests and shrubland; bacterivores were positively correlated with organic-matter and nitrogen content. {N}egative correlations (p{H}, moisture content, organic carbon) were seen in a minority of fungivore and {PPN} genera. {C}orrespondance {A}nalysis illustrated nematodal contributions in substrates and impacts of substrate origin on genera distribution. {D}itylenchus, {A}phelenchoides, {P}rodorylaimus, {L}aimydorus, {D}orylaimellus, and {A}phelenchus were related to grassland, shrub, herbaceous and tree soils. {R}habpanus, {D}iplogastritus, {L}eptolaimus, {T}eratorhabditus, {D}iploscapteroides were related to mixed-cropping, mono-cropping and garden-soils. {M}ixed cropping or organic practices of cultivation improve the nematode community structure and functional diversity. {M}oreover, altitude, soil nutrients, physicochemical factors and vegetation of the {H}imalayan region affect the diversity and abundance of soil nematode communities. {T}hese key areas assist our understanding of future challenges for agroecology, especially in megadiverse locations.},
