Flowering Calendar of the Macrophytes of Keibul Lamjao National Park, Loktak Lake, Manipur, India

Abstract

<div><p><em>Flowering calendar of a particular area will give the information of the period and duration of flowering among plants. The purpose of the study is to investigate the presence of the habitat of some dominant macrophytes in Keibul Lamjao National Park (a Ramsar site) which have ethnobotanical relationships with human beings (the lake dwellers in particular and tourist in general) and wild animals. Flowering calendar of six study sites viz., Keibul, Nongmaikhong, Kumbi, Khordak, Sargam and Toyaching were studied and monthly flowering calendars were taken for two year period (2010 to 2011). Flowering calendars of the macrophytes were surveyed by following standard methodologies and comparison of the stages of flowering period of 6 study sites was incorporated. Maximum number of flowering plants (44) was recorded in Sargam, Khordak (32), Kumbi (30), Nongmaikhong (29) during the period September to November. Whereas, Toyaching reached 35, Keibul recorded lowest plant numbers (14) during the period June to August. Four plant species viz., Ageratum conyzoides, Alternanthera philoxeroides, Leersia hexandra and Hedychium coronarium were found throughout the year in all the 6 sites. From the findings, it can be concluded that flowering calendar will give the information of plants which are used as fodder for the wild animals like Sangai (Rucervus eldii eldii McClelland), an endangered deer species in this globe and ethnobotanically important plants of the lake dwellers as food, medicinal plants and allergens, thereby maintaining health status of man and animals. Conservation is required by controlling the human anthropogenic harassments, thereby maintaining the luxuriant growth of the seasonal and perennial, macrophytes observed during the study of flowering calendar, so as to maintain and conserve the natural flora and fauna of the park.</em></p></div>

Ethnobotanical Plants of Phumdi, Loktak Lake, Manipur, India

“…The collected plant specimens were identified in consultation with available literature and recent publications. [6][7][8][9] For ethnobotanical information, Passport Data Form (PDF) was used, developed by Biodiversity and Conservation Lab., Ambika Prasad Research Foundation, Odisha and methodological framework was followed as per standard technique of ethnobotanical approaches of Christian and Brigitte (2004).…”

“…The matured phumdi of thickness 1.5 ft is cut with 5ft wide and joined to form a ring structure of 500 ft in diameter. [5] The ringed masses of Phumdi (Plate 1.5) are the home of many floral wealth. [6][7][8][9] The local communities use them for different purposes for which the present attempt has been made to enumerate the floral wealth available in and around Athaphum and phytochemical analysis of selected plants.…”

The diversity of aquatic insects in Assam, North-East India: A Review

“…In a preliminary examination of aquatic insect diversity and water quality at Loktak Lake, Manipur, one of the Ramsar sites, six orders and fifteen families were discovered, with the order Hemiptera having the largest number of aquatic insects. Belostomatidae and Corixidae were the most prevalent families (Devi et al, 2013).…”
