Senna spectabilis (DC.) Irwin & Barneby is a tropical American species collected from the forests of Southern Western Ghats. It is reported here as an addition to the flora of Tamil Nadu and Kerala. The detailed description with an illustration and photographs are provided.

This paper presents the results of a household survey designed to qualitatively evaluate the impacts of the invasive alien species Senna spectabilis on the distribution of welfare across dependent communities in the Budongo Forest Reserve (BFR) in Uganda. The BFR is the largest forest reserve in...

Framework species are indigenous tree species planted in a mixed stand to accelerate natural regeneration of forest and encourage biodiversity regeneration. In this study, the framework species method was used to make multipurpose tree gardens to provide traditional healers with woody species used...

The use of participatory research methods in evaluating tree legumes has received little attention among researchers because of the widely-held assumption that data generated in this way are qualitative and not amenable to statistical testing. Using a participatory tool called a bao game, 112...

Conservation in the tropics has focussed on protected areas (PAs) ignoring the unprotected sites. This study assessed the conservation of indigenous plants outside the PAs in Tororo District, eastern Uganda. Data were collected using participatory methods and field surveys, and questionnaires...

Senna spectabilis is a tree native to South and Central America. Thirty-five years ago, it invaded the Mahale Mountains National Park in western Tanzania where it presently covers approximately 225 ha. We quantified its occurrence relative to that of sympatric species of native trees, and compared...

Double hedgerows of two leguminous multipurpose trees Gliricidia sepium (Jacq.) Walp. and Cassia spectabilis DC. were established in highly eroded, low organic matter, acid uplands in northern Mindanao, Philippines. Alleyways were grown with upland rice Oryza sativa L. and fertilised with G. sepium ...

Efforts to overcome declining soil fertility on smallholder farms in western Kenya must be consistent with the reality of low utilization of inorganic fertilizers. Likewise, organic inputs alone cannot supply adequate nutrients. The use of two organic resources, Tithonia diversifolia (tithonia) and ...

For many soils of the tropics, inputs of organic materials are essential to sustain soil fertility and crop production. Research in the quality of organic inputs, a key factor controlling rates of decomposition and nutrient release, continues to guide selection and use of organic materials as...

The response of Zea mays and 14 native tree species to K fertilization was studied in a greenhouse experiment. The species examined included pioneer species such as Peltophorum dubium, Senna spectabilis, Senna multijuga, Stenolobium stans [Tecoma stans], Jacaranda mimosifolia, Guazuma ulmifolia and ...
