Details of ground flora in 8 transects situated in burnt and unburnt Pinus longifolia sample plots are recorded both for June and September. Species peculiar to the burnt and unburnt transects are listed. Area under blanks is greater in the burnt transects which have comparatively less vegetation. Premma hevrbacea, amongst others, is peculiar to the burnt transects. It is the first attempt of work of this kind.- Ecological Succession in Grassland

Based ,on general observations and annual yield figures, it appears that in Nurpur (Kangra district) Themeda anathera, Cenchrus ciliaris and chrysopogon montanus are lower in the scale of succession than Dichanthium annulatum, Bothriochloa perlusa and Heteropogon contortus.- How to Increase Fodder Supplies in the Low Hills, Punjab

A number of soil profiles under the main forest communities of the Bashahr Himalayas have been studied. The climax communities are : Quercus semecarpifolia Quercus incana, Quercus ilex. Besides these, mixed oak-conifer communities and pure conifer communities occurring in the areas occupied by the above climatic climaxes have also been studied. The distribution of different layers on horizons have been shown for each forest community. The amount of loss on ignition, moisture, soil relative humidity, pH and exchangeable Ca has been studied. The mean figures of the above constituents for each forest community were determined. These show very interesting differences in different forest communities. The relationship of various constituents of humus with one another was also studied. The paper marks a definite advance in our knowledge of the casual relationship of oak-conifer communities of the Himalayas with the environment.- The Himalayan Conifers V.

Forest communities in the chir pine forest of the Punjab and Himachal Pradesh have been studied in detail. The three forest types of Mohan have been re-classified into six for the purpose of giving a correlation between the vegetation and soil features and to indicate successional trends. Brief description of these types is given and the trend of succession in these forest communities is described in some detail. The succession proceeds as follows :- (1) On sand rock substratum- Chir pine → Chir pine - Terminalia chebula with an undergrowth mainly of Carissa spinarum. ( 2) On deep alluvium- Chir pine → Mixed chir pine - broad leaved species of Terminalia, Lannea, Albi ia, Cedrela, Eugenia, Phyllanthus, etc. ( 3) On Himalayan schistose rocks- Chir pine → Quercus incana - Rhododendron arboreum - Pieris ovalifolia. ( 4) On moist ferruginous clayey substratum- Chir pine with Carissa or/and Dodonaea → mixed Chir pine broad leaved species. On account of intense biotic features the successional trends outlined above may be slightly altered. In some places intermediate seral stages may become feature of vegetation, at others degraded types may assume different composition, or structure. Soil profiles from the six types have also been studied and the data presented in tabular form.- Artificial Regeneration of Wendlandia Exserta D. C.
