Annual report 2006-07Kerala Forest Research InstituteListed Categories and many of them are knownonly by their type collections made a centuryago. Two new tree species discovered duringthe study and named as Humboldtia sanjappaeand Stereospermum colais var. shendurunii are alsoincluded. Dichotomous parallel keys based ongenerative and vegetative characters are providedin the manual for the identification offamilies, genera, species and infraspecific taxa.The correct botanical name with author(s) nameand citation are provided with basionym andsynonym(s), if any. References to monographs/revisions and floristic studies in Kerala are cited.Local name(s) are also given, if known. Description,habitats (vegetation-wise), geographicaldistribution and district-wise occurrence inKerala are provided along with flowering andfruiting periods.

KFRI Research Report No. 283(Mathew, G., Sharma, J.K. and Easa, P.S., 2006).Biodiversity of selected landscapes at fivedifferent locations was studied with the activeparticipation of college teachers and students.In Cheruvathur Grama Panchayath, the studywas carried out in different habitats such asIndian Flapshell Turtlelateritic plateau, sacred groves, rice fields andhuman settlements. A total of 295 species ofplants belonging to 239 genera under 82 familieswere recorded. With regard to the fauna, sevenfamilies of butterflies, four families of anurans,six families of reptiles, 30 families of birds and13 families of mammals were found representedin the study area. In all locations, thenatural vegetation supported rich biodiversity.Settlements and paddy fields were relativelypoor in biodiversity probably due to pesticideand chemical fertilizer usage.In the case of Muthur Grama Panchayath, 45species of plants comprising trees, herbs andshrubs were recorded which included variousornamental and medicinal plants. With regardto fauna, the anurans such as Jerdon’s bull frogand Marten’s bush frog; the reptiles such asbuffer-striped keelback and common ptyas andthe birds such as black headed oriole, purplerumbed sunbird and purple sunbird werecharacteristic to this area. Several species ofspiders, 24 species of butterflies, six speciesof amphibians, five species of reptiles and 30species of birds have been recorded.In Paliyamangalam, Ayilamudichi Hills(Nemmara), four species of fungi, crustoselichens growing on rocks and tree trunks,bryophytes, pteridophytes, monocots andPathi Kavu Sacred Grove Karur Panchayat, Kottayam14

The faunal elements included severalspecies of rare butterflies including Phalantaphalanta and Castalius rosimon, exotic mollusks(Achatina fullica) and Vaginulus sp., birds such asMalabar grey hornbill and wagtails, andmammals such as sambar deer, spotted deerand wildcat. Of the various ecosystems, themoist deciduous forests contained maximumnumber of species.Biodiversity characterization at landscapelevel using satellite remote sensing (DBT-DOS project) Phase-II study.

The study was undertaken jointly with theDepartment of Space and is part of a majorinitiative taken up by the Department ofBiotechnology under its Network Programmefor Bioprospecting, which commenced in 1997.The programme is a true implementation of‘gene to ecosystem’ concept in biodiversityconservation and prospecting. This project is apioneering effort to create geospatial databaseon vegetation cover types, disturbance regimesand biological richness. The spatial data havebeen linked to the species database and fielddata from different strata of vegetation. Detailedsampling was performed in comparativelyundisturbed forests of Goodrikal Reserve inRanni Forest Division, with an ecologicalinsight to understand the forest dynamics. Theinformation system evolved in the present studythrough multicriteria analysis in GIS facilitatesrapid assessment of biodiversity and itsmonitoring (loss and/or gain), assessment ofnature of habitats and disturbance regimes,evolving species-habitat relationship, mappingbiological richness and gap analysis, andprioritizing conservation and bioprospecting.A very detailed land cover map of the areawas prepared using aerial photographs andsatellite imageries. The density sliced version ofthe cover map was also generated using digitalmapping techniques and is the basis of thesampling site selection. The vegetation data weregathered and analyzed for 25 selected localitiesrepresenting the different forest types and15
