Patterns of diversity and distribution of non-timber forest product species (NTFPs) were studied in three community forests of Dovan VDC, Palpa. Richness of total plant species and NTFP species was compared in different community forests in relation to forest size, altitude, human disturbance and other physical factors. A total of 143 vascular plant species have been documented from the study area among which 114 species were identified as potentially useful species (NTFPs). The gamma diversity of all species as well as NTFP species was high in large-sized community forest and low in smaller-sized community forest indicating area-based increase in habitat heterogeneity in maintaining overall landscape level species diversity. But species richness (alpha diversity) showed pattern related more with the level of human disturbance associated with the management practices.  Key words: Species richness; Alpha diversity; Beta diversity; Gamma diversity; Altitude; Disturbance.  Journal of Natural History MuseumVol. 24, 2009Page: 21-46

The species richness (number of vascular-plant species per unit area) of sclerophyll (heathy) plant communities is examined from south-east Queensland to south-west Western Australia. The species richness of communities of heathy open forest, heathy open scrub, dry heathland and wet heathland is consist- ently similar throughout southern Australia and decreases from dry heathland (on laterite, coastal and inland localities) to heathy open forest, heathy open scrub and wet heathland. Investigation of related microcommunities at Cooloola, Stradbroke Island, Ku-ring-gai Chase and Wilsons Promontory indicates that species richness decreases linearly as overstorey cover increases. In post-fire succession on Stradbroke Island heathy woodland and Dark Island heathland, species richness declines linearly as overstorey cover increases during the regeneration of the community. The appli- cation of limiting fertiliser to Stradbroke Island heathy woodland and Dark Island heathland increases the rate of development of overstorey cover, with a simultaneous decrease in species richness. Species richness of the understorey strata of plant communities appears to be inversely related to the rate of development of foliage projective cover in the overstorey. If an environmental or biotic factor inhibits or retards the development of overstorey cover, the understorey increases in species richness. Conversely, if any environmental or biotic factor accelerates the development of overstorey cover, the understorey species show a reduction in species richness.
